Description:
CROSS REFERENCE TO RELATED APPLICATION 
     The disclosure of Japanese Patent Application No. 2018-088784, filed May 2, 2018, is incorporated herein by reference. 
     FIELD 
     The technology disclosed herein relates to storage media storing information processing programs, information processing apparatuses, information processing systems, and information processing methods. More specifically, the technology disclosed herein relates to, for example, a storage medium storing an information processing program, information processing apparatus, information processing system, and information processing method that execute a process using a player object. 
     BACKGROUND AND SUMMARY 
     There is a game system in which a user acquires a game item and uses the game item in a game. In this game system, each time the cumulative number of game coins acquired in a race reaches a predetermined value, the user can acquire a part (machine part) that can be used in the race. 
     However, in the above game system, there is room for improvement of a motivation for acquiring a consideration (e.g., game coins) that can be used in a game or items (e.g., paid items and virtual currency) that can be acquired by payment. 
     With this in mind, it is an object of the non-limiting example embodiment to provide a storage medium storing an information processing program, information processing apparatus, information processing system, and information processing method that can enhance a motivation for acquiring a consideration or paid items usable in a game. 
     To achieve the above, this non-limiting example embodiment has the following features, for example. It should be understood that the scope of the present technology is defined only by the appended claims. To the extent of any inconsistency or conflict in disclosure between the description and the claims appended hereto, the claims shall prevail. 
     A non-limiting example non-transitory computer-readable storage medium having stored therein an information processing program to be executed by a computer included in an apparatus that executes a game including at least a first game scene and a second game scene, the program causing the computer to execute: in the first game scene, giving a first game object to a user in exchange for a reduction in in-game currency possessed by the user; and in the second game scene, based on a type of the first game object, controlling a player object disposed in a virtual space; based on the player object&#39;s reaching a specific position in the virtual space, first giving a second game object to the user; based on the user&#39;s instruction, second giving the second game object to the user in exchange for a reduction in the in-game currency; and based on use of the second object, applying to the player object an advantageous effect based on a type of the second game object, and the first game object is allowed to be continually used in a plurality of the second game scenes, and the second game object is not allowed to be continually used in a plurality of the second game scene. 
     The second giving may further include applying an additional effect to the player object. 
     In the second game scene, a racing game may be performed, and the additional effect may be to accelerate the player object in the racing game. 
     An upper limit may be set to the number of times the second game object is given by the second giving. 
     The upper limit may be once. 
     In each of the first giving and the second giving, a time lag may be set between the time that a condition for giving the second game object is satisfied and the time that the second game object is actually given, and the time lag set in the second giving may be shorter than the time lag set in the first giving. 
     Based on determination that the second game object given using the first giving has not entirely been consumed, execution of the second giving may be limited. 
     The program may cause the computer to further execute: in the second game scene, controlling an action of the player object according to an input to a region disposed at a middle or lower portion of a touch display; and displaying a button on an upper portion of the touch display, and obtaining a touch operation performed on the button as the user&#39;s instruction in the second giving. 
     In the displaying the button, based on determination that the second game object given by the first giving has not entirely been consumed, the button may not be displayed on the touch display. 
     In the second game scene, a racing game may be performed, and the second game object may be an offensive item that is fired from the player object in the racing game or an acceleration item that is used to accelerate the player object in the racing game. 
     In the second game scene, a racing game may be performed, the first game object may be a vehicle object that is used by the player object in the racing game, and a speed of the vehicle object in the racing game may be changed, depending on performance of the vehicle object. 
     In the second giving, the second game object may be probabilistically given to the user. 
     In the first giving, based on the player object&#39;s passing by or through an item box in the virtual space, the second game object may be given to the user. 
     In addition, the non-limiting example embodiment may be implemented in the form of an information processing apparatus, an information processing system, and an information processing method. 
     Another non-limiting example non-transitory computer-readable storage medium having stored therein an information processing program to be executed by a computer included in an apparatus that executes a game including at least a first game scene and a second game scene, the program causing the computer to function as a first effect setting unit and a second effect setting unit. In the first game scene, the first effect setting unit changes a first parameter, and sets a first effect that is effective in a plurality of the second game scenes. In the second game scene, the second effect setting unit sets a second effect that is effective in the single second game scene, based on determination that a first occurrence condition that a position of a player object disposed in a virtual space and a specific position has a first positional relationship, is satisfied. In the second game scene, the second effect setting unit changes the first parameter or a second parameter set based on a change in the first parameter, and sets the second effect, based on determination that a second occurrence condition that a user has performed an instruction, is satisfied. 
     Accordingly, the first parameter that can be used in the game can be used to obtain the first effect that is effective in a plurality of game scenes. In addition, the second effect that is effective in a single game scene under the satisfied first occurrence condition can also be obtained using the first parameter or the second parameter set based on a change in the first parameter. Therefore, a motivation for acquiring the first parameter can be enhanced. 
     The second effect setting unit may change a type of the second effect according to a first rule, under the satisfied first occurrence condition or second occurrence condition. 
     Accordingly, the type of the second effect is changed according to the first rule. Therefore, amusingness is provided as to what second effect is obtained. As a result, a motivation for acquiring the first parameter can be further enhanced. 
     Under the satisfied second occurrence condition, the second effect setting unit may set, as the second effect, a more advantageous effect compared to under the satisfied first occurrence condition. 
     Accordingly, the second effect is more beneficial. Therefore, a motivation for acquiring the first parameter can be further enhanced. 
     The second effect setting unit may set an upper limit to the number of times the second occurrence condition is satisfied. 
     Accordingly, a level of fairness can be maintained between players participating in the game. 
     In the second effect setting unit, a period of time between the time that the second occurrence condition is satisfied and the time that the second effect is set may be shorter than a period of time between the time that the first occurrence condition is satisfied and the time that the second effect is set. 
     Accordingly, the second effect obtained by changing the first parameter or the second parameter can be obtained relatively early. Therefore, a motivation for acquiring the first parameter can be further enhanced. 
     The second effect setting unit may limit the process of setting the second effect based on the second occurrence condition, based on determination that the second effect based on the first occurrence condition is continued. 
     Accordingly, double occurrence of the second effect is prevented, and therefore, the first parameter or the second parameter can be prevented from being uselessly changed. 
     The first parameter may indicate the amount of in-game currency possessed by the user. In this case, the first effect setting unit and the second effect setting unit may change the first parameter by changing the amount of in-game currency possessed by the user. 
     Accordingly, a motivation for acquiring in-game currency can be enhanced. 
     The first parameter may indicate the amount of in-game currency possessed by the user. In this case, the second parameter may indicate the number of game items purchased using in-game currency or the amount of another type of in-game currency that the above type of in-game currency has been exchanged for and is possessed by the user. 
     Accordingly, a motivation for acquiring in-game currency can be enhanced. 
     The non-limiting example embodiment may be implemented in the form of an information processing apparatus, an information processing system, and an information processing method. 
     According to the non-limiting example embodiment, the first parameter that can be used in the game can be used to obtain the first effect that is effective in a plurality of game scenes. In addition, the second effect that is effective in a single game scene under the satisfied first occurrence condition can also be obtained using the first parameter or the second parameter set based on a change in the first parameter. Therefore, a motivation for acquiring the first parameter can be enhanced. 
     These and other objects, features, aspects and advantages of the present exemplary embodiment will become more apparent from the following detailed description of the present exemplary embodiment when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF NON-LIMITING EXAMPLE EMBODIMENTS 
     An information processing system according to a non-limiting example embodiment will be described with reference to  FIG. 1 . As shown in  FIG. 1 , an information processing system  1  that is a non-limiting example of the information processing system of the non-limiting example embodiment, includes information processing apparatuses  3  and a server  200 , which are connected together through a network  100 . Although  FIG. 1  shows a plurality of information processing apparatuses  3 , the information processing system  1  may include only a single information processing apparatus  3 . 
     The information processing apparatuses  3  are configured to be able to connect to the network  100  through wireless or wired communication. The information processing apparatuses  3  and the server  200  constitute a client-server system. For example, the information processing apparatuses  3  can execute a predetermined application (e.g., a game application, etc.). The information processing apparatuses  3  can connect to and communicate with the server  200  through the network  100  by executing the above predetermined application. For example, the information processing apparatuses  3  can execute an information processing program that is stored in a replaceable storage medium, such as a memory card or an optical disc, or is received from another apparatus. The information processing apparatuses  3  may be a typical personal computer, stationary game machine, mobile telephone, handheld game console, personal digital assistant (PDA), etc. 
     Next, the information processing apparatus  3  will be described with reference to  FIG. 2 .  FIG. 2  is a block diagram showing a non-limiting example configuration of the information processing apparatus  3 . In  FIG. 2 , the information processing apparatus  3  includes a control unit  31 , a storage unit  32 , a program storage unit  33 , an input unit  34 , a display unit  35 , and a communication unit  36 . It should be noted that the information processing apparatus  3  may include one or more devices including an information processing device including at least the control unit  31 , and other devices. 
     The control unit  31  is an information processing means (computer) for executing various information processes, such as a CPU. For example, the control unit  31  has a function of executing the above application to perform information processes such as a game process described below, and data transmission and reception processes through the server  200 . This function is performed by the control unit  31  (e.g., a CPU) executing predetermined programs. 
     The storage unit  32  stores various items of data that are used when the control unit  31  executes the above information processes. The storage unit  32  is, for example, a memory that can be accessed by the control unit  31  (e.g., a CPU). 
     The program storage unit  33  stores programs. The program storage unit  33  may be any storage device (storage medium) that can be accessed by the control unit  31 . For example, the program storage unit  33  may be a storage device that is provided in the information processing device including the control unit  31 , or a storage medium that is removably attached to the information processing device including the control unit  31 . The program storage unit  33  may be a storage device (e.g., a server, etc.) that is connected to the control unit  31  through a network. The control unit  31  (CPU) may read all or a portion of a game program into the storage unit  32  and execute the read program with appropriate timing. 
     The input unit  34  is an input device that can be operated by a user. The input unit  34  may be any suitable input device. As a non-limiting example, the input unit  34  may be a touch panel provided on a screen of the display unit  35 . For example, the touch panel may be of any type. The touch panel may be either of a type that allows a multi-touch input (e.g., a capacitive type) or of a type that allows a single-touch input (e.g., a resistive type). 
     The display unit  35  displays an image according to an instruction from the control unit  31 . It should be noted that when the information processing apparatus  3  is a stationary game apparatus or a personal computer, the display unit  35  may be separated from the information processing apparatus  3 . 
     The communication unit  36 , which is a predetermined communication module, exchanges data with another apparatus (e.g., the server  200 ) or another information processing apparatus  3  through the network  100 . 
     Next, the server  200  will be described with reference to  FIG. 3 .  FIG. 3  is a block diagram showing a non-limiting example configuration of the server  200 . 
     The server  200  has a communication unit  201 , a control unit  202 , and a storage unit  203 . The communication unit  201  communicates with the information processing apparatuses  3 , etc., through the network  100  by exchanging communication packets. As a non-limiting example, the control unit  202  performs a process of managing the progression of a game performed along with the information processing apparatus  3 , a process of managing in-game currency (e.g., coins), game items, and game objects (e.g., pieces of equipment used in a game), etc., that are purchased by the user, a process of managing the probability of winning a slot lottery, and a process of managing information about payment or charging. The control unit  202  also establishes a communication link to the information processing apparatuses  3 , etc., through the communication unit  201 , and performs data transmission control and routing on the network  100 . When a game is performed along with a plurality of information processing apparatuses  3 , the control unit  202  manages a pairing or grouping of information processing apparatuses  3  that perform the game, and data communication between those information processing apparatuses  3 . The storage unit  203  stores programs that are executed by the control unit  202 , various items of data used for the above processes, various items of data used for communication with the information processing apparatuses  3 , etc. When the system employs a predetermined log-in process for data exchange performed through the network  100 , the server  200  may perform an authentication process to determine whether or not a user who tries to log in is an authorized user. The server  200  may be a single server machine or may include a plurality of server machines. 
     Next, before describing specific processes performed by the information processing apparatus  3  and the server  200 , a non-limiting example movement process and firing process performed in the information processing system  1  will be outlined with reference to  FIGS. 4-9 . In the non-limiting example movement and firing processes, the information processing system  1  is used to operate a movement direction of a player object PO (movable object) and firing of an item I (another object). Note that  FIG. 4  is a diagram showing a non-limiting example game image displayed on the display unit  35  of the information processing apparatus  3 .  FIG. 5  is a diagram showing a non-limiting example game image displayed on the display unit  35  of the information processing apparatus  3 .  FIG. 6  is a diagram showing a non-limiting example in which the movement direction of the player object PO is controlled with reference to a display screen.  FIG. 7  is a diagram showing a non-limiting example in which an action of an item I that is fired is controlled with reference to the display screen.  FIG. 8  is a diagram for describing non-limiting example determination regions for determining an operation of firing an item I with reference to the display screen.  FIG. 9  is a diagram for describing non-limiting example determination regions for determining an operation of firing an item I with reference to the player object PO. Although, in the description that follows, a game is used as a non-limiting example application executed in the information processing apparatus  3 , other applications may be executed in the information processing apparatus  3 . 
     The display unit  35  of the information processing apparatus  3  displays a game image corresponding to a game played in the information processing apparatus  3 . As a non-limiting example of such a game image,  FIG. 4  shows a scene in which the player object PO performs a racing game. For example, in the game, the player object PO sits on a cart and drives the cart on a course provided in a virtual world. On the course, an opponent object(s) EO sits on and drives another cart. These objects compete to be first to reach a goal provided on the course. A virtual camera for generating a game image is disposed behind the player object PO traveling on the course. Note that when the player object PO deviates from the travel direction of the course due to spinning, drifting, etc., the virtual camera may be still disposed at a position where the player object PO is seen from behind the player object PO (i.e., the virtual camera is aimed toward the player object PO), or may be disposed at a position where the player object PO is seen from behind along the travel direction of the course (i.e., the virtual camera is aimed in the travel direction of the course). 
     As shown in  FIG. 4 , the movement direction of the player object PO can be controlled by performing an operation of touching the touch panel (input unit  34 ) provided on the screen of the display unit  35 . As a non-limiting example, the player object PO is controlled to automatically travel forward along the course, and the leftward/rightward movement direction of the player object PO is controlled by the user&#39;s operation (e.g., a steering operation). Specifically, when a touch operation of swiping rightward is performed with reference to the position where the touch panel was first touched (initial touch position), the movement direction of the player object PO is changed to a rightward direction. When a touch operation of swiping leftward is performed with reference to an initial touch position, the movement direction of the player object PO is changed to a leftward direction. For example, in  FIG. 4 , the display unit  35  displays a reference image R showing an initial touch position on the touch panel, and a touch position image T showing a current touch position. Because the touch position image T is located to the right of the reference image R, the movement direction of the player object PO is changed to a rightward direction (direction “a” in  FIG. 4 ). Note that the player object PO may not be controlled to automatically travel forward along the course, and may be caused to travel according to the user&#39;s acceleration operation. The player object PO may also be controlled to be automatically steered to turn left and right along the course. For example, when the course curves to the right, the movement direction of the player object PO may be changed to a rightward direction to some extent even without the user&#39;s steering operation, and in this case, when the user performs a rightward steering operation, the movement direction of the player object PO may be changed to a rightward direction to a further extent. 
     In addition, an item I possessed by the player object PO can be fired by performing a touch operation. For example, the display unit  35  is provided with a plurality of possession frames HF each showing an item I possessed by the player object PO. In the non-limiting example possession frames HF of  FIG. 4 , three items I 1 , I 2 , and I 3  can be possessed by the respective possession frames. One of the items I in the possession frames HF possessed by the player object PO is displayed, as a ready-to-use item IP, at a ready-to-use position behind the cart of the player object PO. For example, the ready-to-use item IP is one of the items I in the possession frames HF that was acquired earliest. In the non-limiting example of  FIG. 4 , the item I 1  (a bunch of bananas) displayed in the leftmost possession frame HF is displayed as the ready-to-use item IP at the ready-to-use position. Note that the possession frames HF may be disposed in the virtual space or may overlay the display screen. 
     In  FIG. 5 , when a touch operation of swiping the touch panel upward is performed, then if the ready-to-use item IP disposed at the ready-to-use position of the player object PO is fireable, the item IP is fired as a projectile item IM toward the front of the player object PO. Note that the ready-to-use item IP and the projectile item IM are typically the same object, and alternatively may be different objects. Some types of ready-to-use items IP (e.g., a banana item) disposed at the ready-to-use position may be fired as the projectile item IM toward the back of the player object PO when a touch operation of swiping the touch panel downward is performed. Note that if the direction in which the ready-to-use item IP disposed at the ready-to-use position of the player object PO is fired is fixed, the item IP may be fired as the projectile item IM in the fixed firing direction no matter whether a touch operation of swiping the touch panel is performed upward or downward. Some types of ready-to-use items IP disposed at the ready-to-use position may not be fired from the player object PO and may be used by the player object PO itself. In this case, when a touch operation of swiping the touch panel upward is performed, the ready-to-use item IP disposed at the ready-to-use position of the player object PO is used by the player object PO. 
     When the player object PO fires the projectile item IM, an effect that is advantageous to the progression of a race performed by the player object PO can be obtained, depending on the type of the projectile item IM. For example, when the projectile item IM indicating a carapace collides with the opponent object EO, the collision may decelerate or stop, i.e., obstruct, the traveling of the opponent object EO, and may cause damage to the opponent object EO, depending on the extent of the collision. When the projectile item IM indicating a bunch of bananas collides with the opponent object EO, the projectile item IM may affect the opponent object EO such that the opponent object EO slips on a road, so that the traveling of the opponent object EO is decelerated or stopped. 
     Alternatively, the use of the ready-to-use item IP may temporarily increase the ability of the player object PO itself for a predetermined period of time. For example, when the ready-to-use item IP indicating a mushroom is used, the speed of the player object PO is increased for a predetermined period of time. Note that the use of the ready-to-use item IP may provide an effect of increasing the size of the player object PO itself for a predetermined period of time or an effect of increasing in-game coins possessed by the player object PO. 
     When an item I has been used, the item I is not currently possessed by the player object PO, and therefore, the ready-to-use item IP displayed at the ready-to-use position is erased, and the item I in the possession frame HF corresponding to the ready-to-use item IP is also erased (in the non-limiting example of  FIG. 5 , the item I 1  displayed in the leftmost possession frame HF). As a result, the possession frame HF that has displayed the item I that was fired as the projectile item IM is changed to an empty frame E in which no item I is displayed. 
     As described above, in the non-limiting example movement and firing processes performed in the information processing system  1 , the movement direction of the player object PO is changed when an input of swiping the touch panel is performed leftward or rightward, and the firing operation of the item I is controlled when an input of swiping the touch panel is performed upward or downward. A non-limiting example in which the direction of a swiping input is determined will now be described with reference to  FIGS. 6 and 7 . 
     In  FIG. 6 , the leftward/rightward movement direction of the player object PO is set according to the leftward/rightward component in the display screen of an input of swiping the touch panel. Specifically, in a touch operation on the touch panel, a reference coordinate point R 0  where the touch panel is first touched, and a current touch position coordinate point T of a swipe operation performed following the initial touch, are set based on the display screen coordinate system of the display unit  35 . For example, as shown in  FIG. 6 , in the display screen of the display unit  35 , defined is a display screen coordinate system in which the X-axis (the rightward direction is the positive direction of the X-axis) is a first axis that extends in the leftward/rightward direction of the display screen, and the Y-axis (the upward direction is the positive direction of the Y-axis) is a second axis which extends in the upward/downward direction of the display screen and is orthogonal to the first axis. In this case, the reference coordinate point is set as R 0 (X 0 , Y 0 ), and the current touch position coordinate point T is set as T(Xt, Yt). In this case, the leftward/rightward component (X-axis-direction component) in the display screen of a swipe input is calculated by Xt−X 0 , and the upward/downward component (Y-axis-direction component) in the display screen of the swipe input is calculated by Yt−Y 0 . In the non-limiting example embodiment, if the X-axis-direction component Xt−X 0  has a positive value, the movement direction of the player object PO is changed to a rightward direction by a steering wheel angle corresponding to the absolute value of Xt−X 0 . If the X-axis-direction component Xt−X 0  has a negative value, the movement direction of the player object PO is changed to a leftward direction by a steering wheel angle corresponding to the absolute value of Xt−X 0 . Thereafter, when the touch is released from the touch panel, the reference coordinate point R 0  and the current touch position coordinate point T are initialized, and the movement direction of the player object PO is changed such that the steering wheel angle is returned to the straight-ahead position by a predetermined change amount. 
     Note that the steering wheel angle corresponding to the absolute value of Xt−X 0  may be changed, depending on the position of the player object PO on the course. For example, when the player object PO is traveling at a center of the course, the steering wheel angle set according to the user&#39;s operation may be relatively increased, and when the player object PO is traveling at an end of the course, the steering wheel angle set according to the user&#39;s operation may be relatively decreased. The cart being driven by the player object PO may slip, i.e., drift, depending on the steering wheel angle set according to the user&#39;s operation, the course conditions, the performance of the cart, etc. In this case, the movement direction of the cart of the player object PO is not consistent with the steering wheel angle, and as a result, the movement direction of the player object PO may not completely be consistent with the magnitude of the leftward/rightward component of an input of swiping the touch panel. 
     In  FIG. 7 , an action of an item I that is fired is controlled according to the upward/downward component in the display screen of an input of swiping the touch panel. Specifically, in a touch operation on the touch panel, a reference coordinate point Rm where the touch panel is first touched (the same position as that of the reference coordinate point R 0  when the touch panel is first touched), and a current touch position coordinate point T of a swipe operation performed following the initial touch, are set based on the display screen coordinate system of the display unit  35 . For example, as shown in  FIG. 7 , as in  FIG. 6 , in the display screen of the display unit  35 , defined is a display screen coordinate system in which the X-axis (the rightward direction is the positive direction of the X-axis) is a first axis that extends in the leftward/rightward direction of the display screen, and the Y-axis (the upward direction is the positive direction of the Y-axis) is a second axis that extends in the upward/downward direction of the display screen and is orthogonal to the first axis. In this case, the reference coordinate Rm is set as Rm(Xm, Ym), and the current touch position coordinate point T is set as T(Xt, Yt). Thereafter, a vector FD from the reference coordinate point Rm to the current touch position coordinate point T is calculated, and based on the direction of the vector FD, it is determined whether the direction of the input of swiping the touch panel is upward or downward. 
     In the process of determining the upward/downward component in the display screen of an input of swiping the touch panel, a positional relationship between the reference coordinate point Rm and the current touch position coordinate point T is maintained to satisfy a predetermined condition. If the condition fails to be satisfied, the reference coordinate point Rm is moved so as to satisfy the condition. For example, the length of a path of touch positions (touch input path) formed between the reference coordinate point Rm and the current touch position coordinate point T is greater than a threshold L, the reference coordinate point Rm is moved on the touch input path toward the current touch position coordinate point T (a direction “b” in  FIG. 7 ) such that the length becomes smaller than or equal to the threshold L. Note that the reference coordinate point Rm that is moved on the touch input path toward the current touch position coordinate point T such that the length becomes smaller than or equal to the threshold L, may be moved until the length becomes equal to the threshold L, at a predetermined rate corresponding to the time it takes for the length to become smaller than or equal to the threshold L. Alternatively, the reference coordinate point Rm may be moved such that the length instantaneously becomes smaller than or equal to the threshold L. In the process of moving the reference coordinate point Rm toward the current touch position coordinate point T, touch position coordinate points T that were recorded in the past and are the threshold L or greater away from the current touch position coordinate point T may be successively erased based on the predetermined rate, and the touch position coordinate point T that becomes most previous due to the erasing process may be set as the reference coordinate point Rm. Thus, by causing the reference coordinate point Rm to move along the touch input path, the positional relationship between the reference coordinate point Rm and the current touch position coordinate point T is maintained such that the touch input path length therebetween is smaller than or equal to L, and the vector FD from the moved reference coordinate point Rm to the current touch position coordinate point T is calculated. Note that while a touch input is being performed, the reference coordinate point Rm may be moved on the touch input path such that the reference coordinate point Rm invariably approaches the current touch position coordinate point T even when the length of the touch input path between the reference coordinate point Rm and the current touch position coordinate point T is smaller than the threshold L. 
     If the length of the vector FD is greater than or equal to a predetermined length and the direction of the vector FD is within a determination region, it is determined that an input of swiping the touch panel in the upward or downward direction of the display screen has been performed, and the ready-to-use item IP is fired as the projectile item IM in a direction based on the determination. For example, as shown in  FIG. 8 , a predetermined angle range around the positive direction of the Y-axis as a center thereof is set as a forward-direction determination region UA, and a predetermined angle range around the negative direction of the Y-axis as a center thereof is set as a backward-direction determination region LA. If the length of the vector FD is greater than or equal to the predetermined length and the direction of the vector FD is within the forward-direction determination region UA, the ready-to-use item IP is fired as the projectile item IM toward the front of the player object PO (e.g., directly toward the front of the player object PO). In the case where the ready-to-use item IP is fireable toward the back of the player object PO, if the length of the vector FD is greater than or equal to the predetermined length and the direction of the vector FD is within the backward-direction determination region LA, the ready-to-use item IP is fired as the projectile item IM toward the back of the player object PO (e.g., directly toward the back of the player object PO). 
     Note that the angle range of the backward-direction determination region LA may be set greater than the angle range of the forward-direction determination region UA. Typically, the downward swipe input using a touch panel is more difficult than the upward swipe input. This is particularly significant when a touch operation is performed using the thumb of a hand holding the information processing apparatus  3 . Therefore, if the condition for determining the relatively difficult swipe input is relatively relaxed, operability can be improved. In addition, the predetermined length for determining the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T may be a threshold that is changed, depending on the direction in which the length is determined. In order to relax the condition for determining the relatively difficult swipe input for the above reason, the length of the touch input path required for determination of whether or not a swipe input is within the backward-direction determination region LA may be smaller than the length of the touch input path required for determination of whether or not a swipe input is within the forward-direction determination region UA. While, in the above process, the reference coordinate point Rm is assumed to move along the touch input path, the movement of the reference coordinate point Rm is not limited to this. For example, the reference coordinate point Rm may be moved on a straight line connecting between the reference coordinate point Rm and the current touch position coordinate point T toward the current touch position coordinate point T such that the linear distance therebetween becomes smaller than or equal to a threshold L. Alternatively, the reference coordinate point Rm may be fixed to the same position as that of the reference coordinate point R 0 , i.e., an initial touch position. 
     The length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T, which is used in the input determination, may be replaced with other parameters. As a first non-limiting example, the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T may be replaced with the linear distance between the reference coordinate point Rm and the current touch position coordinate point T. As a second example, the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T may be replaced with the length of the Y-axis component of the vector FD. As a third example, the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T may be replaced with the length of the vector FD. 
     The process of determining the upward/downward component in the display screen of an input of swiping the touch panel may be performed without the use of the reference coordinate point Rm. As a first non-limiting example, when the change rate of a touch position in swiping to the current touch position coordinate point T (e.g., the length between the previously detected touch position coordinate point T to the currently detected touch position coordinate point T, or the length of a touch input path immediately previously detected for a predetermined period of time) is greater than or equal to a reference value, then if the direction of the swipe input whose change rate has been detected is within the forward-direction determination region UA or the backward-direction determination region LA, it may be determined that the input of swiping the touch panel has been performed in the upward direction or the downward direction of the display screen. As a second example, when the change rate of a touch position in swiping to the current touch position coordinate point T is greater than or equal to the reference value, then if the length of the Y-axis-direction component of the swipe input whose change rate has been detected is greater than or equal to the predetermined length, it may be determined that the input of swiping the touch panel has been performed in the upward direction or the downward direction of the display screen. 
     The predetermined length that is a reference value for determining the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T may be changed, depending on the user&#39;s swipe input. For example, if the magnitude of the leftward/rightward component Xt−X 0  of the swipe input is greater than or equal to a predetermined threshold, the predetermined length that is the reference value may be changed. As a non-limiting example, when the magnitude of the leftward/rightward component Xt−X 0  of the swipe input is greater than or equal to the predetermined threshold, then if the predetermined length that is the reference value is increased, the player object PO&#39;s operation of greatly turning the steering wheel to the left or right, or the player object PO&#39;s operation of performing so-called drifting, i.e., an operation of performing a swipe input having a great change amount, can be prevented from being determined to be an operation of firing an item forward or backward, which is not actually intended by the user. As another non-limiting example, when the magnitude of the leftward/rightward component Xt−X 0  of a swipe input is greater than or equal to the predetermined threshold, then if the predetermined length that is the reference value is decreased, an operation of firing an item I can be performed during the player object PO&#39;s operation of greatly turning the steering wheel to the left or right, or the player object PO&#39;s operation of performing so-called drifting, without a significant influence of the firing operation on the leftward/rightward movement direction. 
     In the above non-limiting example embodiment, if the conditions that the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T is greater than or equal to a predetermined length, and the direction of the vector FD is within a determination region, are satisfied, the projectile item IM is fired directly toward the front or back of the player object PO. This can avoid the situation that if only the upward/downward component of a swipe input is used in the determination, it may be determined that the user instructs to fire even when the user intends to and actually performs a leftward/rightward swipe input, because the swipe input contains an upward/downward component. By setting the above conditions, an input can be correctly determined. In addition, by limiting the firing direction to the direct forward direction or direct backward direction of the player object PO, an input error from that direction can be accommodated, and therefore, the difficulty of the operation can be taken into consideration. However, in the case where such an effect is not desired, the direction in which the projectile item IM is fired may deviate from the direct forward direction or direct backward direction of the player object PO. For example, if the direction of the vector FD is within the forward-direction determination region UA, the projectile item IM may be fired in a direction deviating from the direct forward direction of the player object PO by an angle difference between the positive direction of the Y-axis and the direction of the vector FD. Also, if the direction of the vector FD is within the backward-direction determination region LA, the projectile item IM may be fired in a direction deviating from the direct backward direction of the player object PO by an angle difference between the negative direction of the Y-axis and the direction of the vector FD. 
     The direction in which the projectile item IM is fired may be varied, depending on the type of the player object PO or a piece of equipment used by the player object PO (e.g., a cart driven by the player object PO). 
     In the process of determining an input of swiping the touch panel, the touch input direction is determined with reference to the coordinate axes (X- and Y-axes) defined in the display screen of the display unit  35 . Alternatively, the touch input direction may be determined with reference to other coordinate axes. For example, as shown in  FIG. 9 , the touch input direction may be determined with reference to coordinate axes defined in the player object PO. 
     In  FIG. 9 , the player object PO is displayed, facing rightward in the display screen of the display unit  35 . A player object coordinate system is defined in which the x-axis (the rightward direction of the player object PO is the positive direction of the x-axis) is a first axis that is the leftward/rightward direction of the player object PO, and the y-axis (the forward direction of the player object PO is the positive direction of the y-axis) is a second axis that is the forward/backward direction of the player object PO and is orthogonal to the first axis. Even in the case where such a coordinate system is used, the reference coordinate point R 0  for determining the leftward/rightward direction of a swipe operation is set as R 0 (x 0 , y 0 ), and the current touch position coordinate point T is set as T(xt, yt). As a result, the magnitude of the leftward/rightward component (x-axis-direction component) of a swipe input with reference to the player object PO can be calculated by xt−x 0 , and the magnitude of the forward/backward direction component (y-axis-direction component) of a swipe input with reference to the player object PO can be calculated by yt−y 0 . If the x-axis-direction component xt−x 0  has a positive value, the movement direction of the player object PO is changed to a rightward direction by a steering wheel angle corresponding to the absolute value of xt−x 0 . If the x-axis-direction component xt−x 0  has a negative value, the movement direction of the player object PO is changed to a leftward direction by a steering wheel angle corresponding to the absolute value of xt−x 0 . When a touch is released from the touch panel, the reference coordinate point R 0  and the current touch position coordinate point T are initialized, and the movement direction of the player object PO is changed such that the steering wheel angle is returned to the straight-ahead position by a predetermined change amount. 
     In the player object coordinate system, the reference coordinate point Rm for determining the forward/backward direction of a swipe operation with reference to the player object PO is set as Rm(xm, xm). A vector FD from the reference coordinate point Rm to the current touch position coordinate point T is calculated, and based on the direction of the vector FD, it is determined whether the input of swiping the touch panel corresponds to the forward direction or the backward direction of the player object PO. If the length of a touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T is greater than a threshold L, the reference coordinate point Rm is moved along the touch input path toward the current touch position coordinate point T such that the length becomes smaller than or equal to the threshold L. If the length of the vector FD is greater than or equal to a predetermined length, and the direction of the vector FD is within a determination region, it is determined that the input of swiping the touch panel has been performed in the forward direction or backward direction of the player object PO, and the ready-to-use item IP is fired as the projectile item IM in the direction based on the determination. 
     For example, in the player object coordinate system, determination regions shown in  FIG. 9  are used. For example, in the player object coordinate system, a predetermined angle range around the positive direction of the y-axis that is the forward direction of the player object PO, as a center thereof, is set as a forward-direction determination region UAp, and a predetermined angle range around the negative direction of the y-axis that is the backward direction of the player object PO, as a center thereof, is set as a backward-direction determination region LAp. If the length of the vector FD is greater than or equal to a predetermined length and the direction of the vector FD is within the forward-direction determination region UAp, the ready-to-use item IP is fired as the projectile item IM toward the front of the player object PO (e.g., in the direct forward direction of the player object PO). If the ready-to-use item IP is fireable toward the back of the player object PO, the length of the vector FD is greater than or equal to a predetermined length, and the direction of the vector FD is within the backward-direction determination region LAp, the ready-to-use item IP is fired as the projectile item IM toward the back of the player object PO (e.g., in the direct backward direction of the player object PO). Note that the direct forward direction of the player object PO may be either the direction in which the front of the player object PO faces or the direct upward screen direction of the display screen (i.e., the direction in which the virtual camera and the player object PO are connected together). 
     Note that when the player object PO is turned and displayed, the forward-direction determination region UAp and the backward-direction determination region Lap set for the player object coordinate system are turned by an angle corresponding to the turn of the player object PO displayed, and are set for the display screen. In this case, the ranges of the forward-direction determination region UAp and the backward-direction determination region Lap may be increased or decreased when these regions are turned and set for the display screen. 
     Thus, in the player object coordinate system, when the orientation of the player object PO displayed in the display screen is changed, the coordinate axes (x- and y-axes) for determining a swipe direction are changed. Therefore, in the case where the player object coordinate system is used, the user who performs a touch operation on the touch panel can perform a swipe operation having high reality with reference to the orientation of the player object PO, resulting in an intuitive touch operation with reference to the direction of the player object PO being displayed. Note that the orientation of the player object PO which is a reference in the player object coordinate system, may be either the orientation of the cart driven by the player object PO or the orientation of the player object PO driving the cart. When the player object PO is driving the cart, the player object PO and the cart may have different orientations. The forward-direction determination region UAp and the backward-direction determination region Lap may be set with reference to any of these orientations. Meanwhile, the coordinate axes (X- and Y-axes) defined in the display screen of the display unit  35  remain fixed to the display screen even when the direction of the player object PO displayed in the display screen is changed. Therefore, in the case where the coordinate axes defined in the display screen are used, the user who performs a touch operation on the touch panel can perform a swipe operation using the fixed coordinate axes, and therefore, can perform a touch operation using a simple operation method that is fixed irrespective of the direction of the player object PO. In the case where the coordinate axes defined in the display screen are used, the coordinate axes for determining a touch operation are fixed, and therefore, the load of a process for the determination can be reduced. 
     Note that in the process of determining the touch input direction, different coordinate axes may be used for different touch input directions to be determined. As a non-limiting example, the magnitude of the leftward/rightward component of an input of swiping the touch panel may be detected and determined using the display screen coordinate system of the display unit  35 , and the upward/downward direction (the forward/backward direction of the player object PO) of an input of swiping the touch panel may be detected using the player object coordinate system. As another non-limiting example, the magnitude of the leftward/rightward component of an input of swiping the touch panel may be detected and determined using the player object coordinate system, the upward/downward direction of an input of swiping the touch panel may be detected using the display screen coordinate system of the display unit  35 . Even in such a case where the touch input direction is determined using different coordinate systems in parallel, the touch input direction can be similarly determined by setting the reference coordinate points R 0  and Rm and the current touch position coordinate point T in the respective coordinate systems. 
     While, in the above description, the operation determination using the display screen coordinate system and the operation determination using the player object coordinate system are used, the user may be allowed to select one of the coordinate systems for each object to be operated. Because both of the coordinate systems have respective advantages as described above, if the user is allowed to select depending on their preference, operability can be further improved. 
     Concerning the use of an item, an item I in a possession frame HF or the ready-to-use item IP at the ready-to-use position, which is displayed on the display screen, may be used by performing a touch operation (e.g., tap operation) on that item displayed on the touch panel. Specifically, the ready-to-use item IP is used at the timing that that item on the touch panel is first touched or at the timing that a touch is released from that item on the touch panel after being first touched thereon. In this case, if the item operated by such a touch operation is a type of object that is fireable from the player object PO, the direction in which the item is to be fired may be set to a default direction. Note that even when an item I in a possession frame HF or the ready-to-use item IP at the ready-to-use position, which is displayed on the display screen, is used by performing a touch operation on that item on the touch panel, the direction in which that item is fired may be changed, depending on the direction of a swipe operation (drag operation) (e.g., the upward direction or downward direction of the display screen). 
     The sizes of the determination regions for determining the input direction (the forward-direction determination region UA, the backward-direction determination region LA, the forward-direction determination region UAp, and the backward-direction determination region LAp) may be changed, depending on the action of the player object PO. For example, when the player object PO performs an action of facing in a direction different from the direction of the steering wheel angle (e.g., a drifting action, a spinning action, etc.), the sizes of the determination regions may be changed and reduced. When the player object PO performs an action of facing in a direction different from the direction of the steering wheel angle, the direction input by the user may fall within a determination region despite the operating user&#39;s intention. Therefore, by reducing the determination regions according to the action of the player object PO, the operation determination can be less likely to be contrary to the user&#39;s intention. 
     In the above description, the movement direction of the player object PO is controlled based on the magnitude of the leftward/rightward component of an input of swiping the touch panel. As long as at least the magnitude of the leftward/rightward component is used, other operations and other direction components may additionally be used. As a non-limiting example, only if a predetermined operation (e.g., an operation of pressing down a predetermined operation button, or a touch operation on a predetermined operation button image) is being performed, the movement direction of the player object PO may be controlled based on the magnitude of the leftward/rightward component of an input of swiping the touch panel. As another non-limiting example, the movement direction of the player object PO may be controlled based on the magnitudes of the leftward/rightward component and upward/downward component of an input of swiping the touch panel. In this case, the leftward/rightward movement direction of the player object PO is controlled based on the upward/downward component and leftward/rightward component of a swipe input. As a non-limiting example, a rightward steering amount may be set to 2 if the leftward/rightward component and upward/downward component of a swipe input are +1.73 and +1.00, respectively. 
     The action of an item I is controlled based on the upward/downward component of an input of swiping the touch panel. As long as at least the upward/downward component is used, other operations and other direction components may additionally be used. As a non-limiting example, only if a predetermined operation (e.g., an operation of pressing down a predetermined operation button, or a touch operation on a predetermined operation button image) is being performed, the action of an item I may be controlled based on the magnitude of the upward/downward component of an input of swiping the touch panel. As another non-limiting example, the action of an item I may be controlled based on the upward/downward component and leftward/rightward component of an input of swiping the touch panel. In this case, the firing of an item I may be controlled based on the upward/downward component of a swipe input, and the direction of the item I fired may be controlled based on the leftward/rightward component of the swipe input. 
     While, in the above description, the movement direction of the player object PO is controlled based on the magnitude of the leftward/rightward component of an input of swiping the touch panel, other elements may be controlled. For example, in the case where a game image as viewed from the player object PO (i.e., a subjective view) is displayed, the movement direction of a virtual camera for generating the game image may be controlled based on the magnitude of the leftward/rightward component of an input of swiping the touch panel. In addition, although the action of an item I is controlled based on the upward/downward component of an input of swiping the touch panel, other elements may be controlled. For example, actions such as an action of firing a beam, an action of changing pieces of equipment, an action of changing targets, and an action of changing viewing fields or viewing directions, may be controlled based on the upward/downward component of an input of swiping the touch panel. 
     In the above non-limiting example embodiment, if the conditions that the length of the vector FD is greater than or equal to a predetermined length and the direction of the vector FD is within a determination region, the ready-to-use item IP is fired as the projectile item IM in a direction based on the determination. Alternatively, the ready-to-use item IP may be fired as the projectile item IM with other timing. For example, if the conditions that the length of the vector FD is greater than or equal to a predetermined length and the direction of the vector FD is within a determination region are satisfied, then when a touch is released from the touch panel, the ready-to-use item IP may be fired as the projectile item IM in a direction based on the determination. 
     While, in the non-limiting example embodiment, the position (ready-to-use position) where an item I is fired as the projectile item IM is set to a rear portion of the cart driven by the player object PO, an item I may be fired at other positions. As a non-limiting example, the projectile item IM may be fired from other portions of the cart driven by the player object PO, such as a front portion of the cart driven by the player object PO, or from near the cart. As another non-limiting example, the ready-to-use position may be set at a firing position provided at an upper or lower end of the display screen or outside the course, and the projectile item IM may be fired from such a position away from the cart driven by the player object PO. 
     The speed at which the fired projectile item IM moves may be set according to the type of the projectile item IM, or may be changed according to the user&#39;s input. For example, the speed at which the fired projectile item IM moves may be changed according to the speed of a swipe input for firing the projectile item IM (the speed at which a touch position is moved during the swipe input). 
     In the above description, if the length of the vector FD is greater than or equal to a predetermined length and the direction of the vector FD is within a determination region, it is determined that a swipe input has been performed on the touch panel in the upward direction or downward direction of the display device, and the ready-to-use item IP is fired as the projectile item IM in a direction based on the determination. Alternatively, the direction of a swipe input may be determined using the touch input path. For example, if the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T is greater than or equal to a predetermined length, and the direction of the vector FD is within a determination region, it may be determined that a swipe input has been performed on the touch panel in the upward direction or downward direction of the display device. 
     Here, in the case where the direction of a swipe input is determined using the difference between a touch position coordinate point T a predetermined time before and a current touch position coordinate point T, the determination of the swipe input direction is not completed until the predetermined time has passed since the initial touch. As a non-limiting example, in the case where the determination of the swipe input direction is performed using a condition that the difference between the touch position coordinate point T of a touch performed 0.5 sec before and the current touch position coordinate point T is greater than or equal to a predetermined value, the swipe input determination may not be performed for 0.5 sec even when great swiping is performed immediately after the initial touch. This may reduce responsiveness for firing an item, which may feel unnatural to the user. Meanwhile, in the case where the swipe input direction is determined using the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T, when great swiping is performed immediately after the initial touch, the swipe input direction is immediately determined, and therefore, responsiveness for firing an item is improved, so that the user does not feel unnatural. 
     Note that as described above, when the length of the touch input path is greater than the threshold L, more previous records are deleted from the records of touch position coordinate points T at a predetermined rate until the length of the touch input path is smaller than the threshold L, and after the deletion, the most previous touch position coordinate point T is set as the reference coordinate point Rm. Thus, when the length of the touch input path is greater than the threshold L, the process of resetting a more recent touch position coordinate point T of the records of touch position coordinate points T as a new reference coordinate point Rm is repeatedly performed until the length of the touch input path is smaller than or equal to the threshold L. The resultant touch input path and reference coordinate point Rm are used to perform the above determination of the swipe input direction. In the case where the process of resetting a more recent touch position coordinate point T of the records of touch position coordinate points T as a new reference coordinate point Rm is thus performed, it is desirable that the “predetermined length” in the above condition that the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T is greater than or equal to a predetermined length, which is a determination condition for determining that a swipe input has been performed, should be set smaller than the threshold L. 
     Alternatively, the reference coordinate point Rm may be reset based on a period of time for which a touch input is being performed. For example, only a portion of the records of touch position coordinate points T stored as the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T that corresponds to a predetermined number of times of processing (e.g., five records of touch position coordinate points T corresponding to five frames) may be stored, and the swipe input direction may be determined using the portion of the records. As a non-limiting example, a value obtained by comparing a touch position coordinate point T that is the most previous of the records and the current touch position coordinate point T that is the most recent record may be used as the touch input path. In this case, the touch position coordinate point T that is the most previous record serves as the reference coordinate point Rm. Thus, when the length of a touch input time for which a touch operation is continued to generate a touch input path is greater than a predetermined time (e.g., five frames), the process of resetting a newer touch position coordinate point T of the records of touch position coordinate points T as a new reference coordinate point Rm is repeatedly performed so that the time it takes to generate the touch input path becomes smaller than or equal to the predetermined period of time, and the resultant touch input path and reference coordinate point Rm are used to perform the above determination of the swipe input direction. Note that if the records are not many enough for the predetermined number of times of processing, a value obtained by comparing a touch position coordinate point T that is the most previous record and the current touch position coordinate point T that is the most recent record may be used as the touch input path. Note that these features of resetting of the reference coordinate point Rm based on the period of time for which a touch input is being performed can be applied, as appropriate, to either the process using the “vector FD” or the process using the “touch input path.” 
     The predetermined length that is a threshold for determining the length of the vector FD or the length of the touch input path may be set differently between the determination of an upward swipe operation and the determination of a downward swipe operation. As a non-limiting example, the predetermined length set for the determination of a downward swipe operation may be smaller than the predetermined length set for the determination of an upward swipe operation so that a downward swipe operation that is relatively difficult can be more easily determined. 
     The predetermined length that is a threshold for determining the length of the vector FD or the length of the touch input path may be changed, depending on a period of time that has passed since the initial touch. As a non-limiting example, if the period of time for which a touch operation is continued is less than 0.2 sec, that period of time may be 0.25 times as long as the threshold that is set when the period of time is longer than or equal to 0.2 sec. As a result, when a swipe operation is performed immediately after the initial touch, the swipe operation can be easily determined. 
     The predetermined length that is a threshold for determining the length of the vector FD or the length of the touch input path may be set differently between the determination of a swipe operation in one direction and the subsequent determination of a swipe operation in the other direction. As a non-limiting example, when a touch operation is continued even after it is determined that a swipe operation has been performed in one of the upward direction and the downward direction, the predetermined length for determining a swipe operation in the other of the upward direction and the downward direction may be increased by a factor of 1.5. As a result, even in the case where the user tends to move their finger performing a touch operation backward to return the finger to the original touch position after performing a swipe operation in one direction, the determination of a swipe operation performed despite the user&#39;s intention can be prevented. Note that when the predetermined length that is a threshold for determining the length of the vector FD or the length of the touch input path is changed and increased, the threshold L for maintaining the length of the touch input path formed between the reference coordinate point Rm and the current touch position coordinate point T may also be changed and increased (e.g., the threshold L may be increased by a factor of 1.5). 
     Next, a first item lottery process example performed in the information processing system  1  will be outlined with reference to  FIGS. 10-14 . In the first item lottery process example, if items I (game objects) possessed by the player object PO satisfy a predetermined combinational condition, an effect relatively advantageous to progression of a game is given to the player object PO. Note that  FIG. 10  is a diagram showing a non-limiting example game image displayed on the display unit  35  of the information processing apparatus  3 .  FIG. 11  is a diagram showing a non-limiting example game image displayed on the display unit  35  of the information processing apparatus  3 .  FIG. 12  is a diagram showing a non-limiting example state transition of items I possessed in the possession frames HF.  FIG. 13  is a diagram showing another non-limiting example state transition of items I possessed in the possession frames HF.  FIG. 14  is a diagram showing a non-limiting example lottery table. 
     As in  FIGS. 4 and 5 , in  FIG. 10 , a game image corresponding to a game played in the information processing apparatus  3  is displayed on the display unit  35  of the information processing apparatus  3 . As a non-limiting example,  FIG. 10  shows a scene that the player object PO performs a racing game. For example, in the game, the player object PO is sitting on and driving a cart on a course provided in a virtual world, and can acquire a new item I by passing by or through an item box IB placed on the course and thereby opening the item box IB. Note that the player object PO can acquire a new item I only if there is a possession frame HF that is an empty frame E. 
     When the player object PO passes by or through an item box IB and thereby opens the item box IB, a lottery event for acquiring a new item I is performed. For example, a lottery event display (hereinafter referred to a rotation lottery display) that a plurality of types of items I are shuffled and successively displayed in a possession frame HF that is an empty frame E in a drum-spin or flip fashion, and thereafter, any one of the items I is displayed in a stationary state in the possession frame HF, showing that the item I displayed in a stationary state in the possession frame HF is finally acquired in the lottery. For example,  FIG. 10  shows a non-limiting example in which in response to the player object PO passing by or through an item box IB, rotating display items IR indicating that a plurality of types of items I are successively displayed and a lottery is being performed are displayed, i.e., the rotation lottery display is being performed, in all the possession frames HF (three frames). Note that the lottery for acquiring an item I is not performed for a possession frame HF in which an item I is already displayed. Specifically, when a possession frame HF that is an empty frame E and a possession frame HF that is displaying an item I coexist, the lottery is performed only for the empty frame E. When there is no possession frame HF that is an empty frame E, the lottery is not performed, and therefore, in this situation, the player object PO cannot acquire a new item I by a lottery. Note that even when the player object PO has not yet reached a position where an item box IB is placed, a lottery event for acquiring a new item I may be performed if the specific position where the item box IB is placed and the position of the player object PO have a predetermined positional relationship. For example, when the player object PO reaches within a predetermined distance of an item box IB, passes above or below an item box IB, or passes through a ring-shaped item box IB, a lottery event for acquiring a new item I may be performed. Note that an item box IB may be placed at a specific position on the course, or may appear on the course at any suitable position as time passes. 
     Item I that are displayed in a stationary state in possession frames HF are finally acquired by the player object PO through a lottery. After the acquisition, the items I can be used by the player object PO one by one in a predetermined order (e.g., the order in which the items I have been acquired). By using an item I, the player object PO can obtain an effect advantageous to progression of a race. 
     As shown in  FIG. 11 , in the non-limiting example embodiment, if the same items I are finally displayed in all the possession frames HF in a lottery, the user wins a so-called “fever state” and can obtain an effect more advantageous to progression of a race performed by the player object PO. As a non-limiting example, when the player object PO is in the “fever state,” an item that has caused the “fever state” can be continuously used for a predetermined fever period of time. Note that as can be seen from the description below, a unique object ID is set for each item I, and whether or not the “fever state” has been established is determined using objects ID set in the possession frames HF. Note that the fever period may be varied, depending on equipment or the like used by the player object PO. 
     For example, in the non-limiting example of  FIG. 11 , the item I 1  that is a carapace is displayed in a stationary state in the leftmost possession frame HF, the item I 2  that is a carapace is displayed in a stationary state in the middle possession frame HF, and the item I 3  that is a carapace is displayed in a stationary state in the rightmost possession frame HF, i.e., the same carapace item I is finally displayed in all the possession frames HF in a lottery. In this case, the “fever state” caused by carapace items is continued for a predetermined period of time, and an advantageous effect obtained by using a carapace item is given to the player object PO only during the predetermined fever period. For example, in the “fever state” caused by carapace items, a plurality of carapace items IF are disposed around the player object PO, indicating the “fever state” caused by carapace items to the user. When the user is performing a certain touch operation on the touch panel, a projectile carapace item IM is continually fired toward the front of the player object PO at predetermined intervals. Thus, while a single projectile carapace item IM can be fired from the player object PO when a carapace item I is used in a normal state, multiple projectile carapace items IM can be continually fired from the player object PO in the “fever state” caused by carapace items. In the “fever state,” a projectile carapace item IM is continually fired at predetermined intervals without performing a swipe operation for firing the item. Therefore, an item can be repeatedly used while controlling the movement direction of the player object PO by a touch operation. Furthermore, while an item I can be used once for each possession frame HF in the normal state, i.e., the same number of items I as the possession frames HF (e.g., three) can be used, an indefinite number of items (i.e., greater than or equal to the number of possession frames HF, e.g., four or more) can be continually used without being limited to the number of possession frames HF during the fever period in which the “fever state” caused by the same three items I is continued. Therefore, the fever state is more advantageous to the user than in the normal state. 
     Note that in the “fever state,” the direction of the projectile item IM fired from the player object PO may be fixed to a predetermined direction (e.g., the direct forward direction of the player object PO), or may be fired in a random direction around the player object PO each time. When, in the “fever state,” the vector FD satisfying the condition for firing the projectile item IM (i.e., the length of the vector FD is greater than or equal to a predetermined length and the direction of the vector FD is within the forward-direction determination region UA or the backward-direction determination region LA) is set, the projectile item IM may be fired based on the direction of the vector FD each time. 
     In the “fever state,” the number of items IF that are disposed and displayed around the player object PO may be reduced as time passes during the fever period. This allows the user of the information processing apparatus  3  to know the remaining time of the fever period from the number of displayed items IF. Note that an image for notifying the user of the remaining time of the fever period by reducing the number of displayed items IF may not be of a plurality of items IF disposed around the player object PO. For example, the number of items I displayed in the possession frames HF may be reduced as time passes during the fever period. 
     Next, a non-limiting example progression of a game in which a new item I is acquired through a lottery (the states of possession frames HF transition) will be described with reference to  FIGS. 12 and 13 . 
     In  FIG. 12 , in a state A in which the possession frames HF are in an initial state, all the possession frames HF are an empty frame E. In the state A, when the player object PO passes by or through an item box IB and thereby opens the item box IB, an item lottery is performed for all the possession frames HF. As a result, a state B occurs in which the rotation lottery display of a rotating display item IR is performed in each possession frame HF. Note that in the state B, the probability of winning the “fever state” is controlled, which is described below. 
     When the item lottery is won to get the “fever state” in the state B, a state C occurs in which the same item I is finally displayed in a stationary state in all the possession frames HF. For example, in the state C, a carapace item I 1  is displayed in a stationary state in the leftmost possession frame HF, a carapace item I 2  is displayed in a stationary state in the middle possession frame HF, and a carapace item I 3  is displayed in a stationary state in the rightmost possession frame HF. Thus, in the state C, it is shown that as a result of the item lottery in the state B, the user has won the “fever state” caused by carapace items in which the same carapace item I is finally displayed in all the possession frames HF. As a result, the player object PO performs a race in the “fever state” caused by carapace items. 
     When a predetermined fever period has passed since the occurrence of the “fever state” caused by carapace items, a state D occurs in which the “fever state” of the player object PO ends, and all the possession frames HF are an empty frame E. Thus, all the possession frames HF are an empty frame E, and therefore, an item lottery can be performed again for all the possession frames HF. 
     In the state D, when the player object PO passes by or through another item box IB and thereby opens the item box IB, an item lottery is performed again for all the possession frames HF. As a result, a state E occurs in which the rotation lottery display of a rotating display item IR is performed for all the possession frames HF. 
     When the item lottery is lost in the state E, a state F occurs in which at least one different item I is finally displayed in a stationary state in all the possession frames HF. For example, in the state F, the same carapace items I 1  and I 3  are displayed in a stationary state in the leftmost and rightmost possession frames HF, and a different item I 2  (banana) is displayed in a stationary state in the middle possession frame HF. Thus, in the state F, it is shown that the item lottery in the state E is lost. The items I 1 -I 3  displayed in the possession frames HF in the state F can be individually used by the player object PO. 
     In  FIG. 13 , when the item I 1  displayed in the leftmost possession frame HF in the state F has been used, a state G occurs in which the leftmost possession frame HF is an empty frame E. Thus, when at least one possession frame HF is an empty frame E, an item lottery can be performed for the empty frame E. 
     In the state G, when the player object PO passes by or through another item box IB and thereby opens the item box IB, an item lottery is performed for the empty frame E that is the leftmost possession frame HF. As a result, a state H occurs in which the rotation lottery display of a rotating display item IR is performed only for the empty frame E that is the leftmost possession frame HF. However, in the state H, the different items I 2  and I 3  are already finally displayed in the middle possession frame HF and the rightmost possession frame HF, and therefore, the item lottery is lost even when any item I is finally displayed in the empty frame E that is the leftmost possession frame HF, so that a state I occurs in which an item I 1  is displayed in a stationary state in the leftmost possession frame HF. As a non-limiting example, the items I displayed in the possession frames HF can be used in a first-in, first-out (FIFO) method. Specifically, in the state I, the item I 1  has most recently been acquired of the items I 1 -I 3  displayed in the possession frames HF, and therefore, the item I 1  is the last to be used when the player object PO uses the items I 1 -I 3 . Note that the order in which the items I displayed in the possession frames HF are used is not limited to the FIFO (first-in, first out) method. For example, an item I to be used may be selected by the user performing an operation of selecting that item displayed in a possession frame HF (e.g., an operation of touching that item I on the touch panel). 
     When the item I 2  displayed in the middle possession frame HF and the item I 3  displayed in the rightmost possession frame HF in the state I have been used, a state J occurs in which the middle and rightmost possession frames HF are an empty frame E. Thus, the two possession frames HF are an empty frame E, and therefore, an item lottery can be performed for the two empty frames E. 
     In the state J, when the player object PO passes by or through another item box IB and thereby opens the item box IB, an item lottery is performed for the empty frames E that are the middle and rightmost possession frames HF. As a result, a state K occurs in which the rotation lottery display of a rotating display item IR is performed for the empty frames E that are the middle and rightmost possession frames HF. Here, although the item I 1  is already finally displayed in the leftmost possession frame HF in the state J, the “fever state” can be won if the same type of item I as the item I 1  is finally displayed in the empty frames E that are the middle and rightmost possession frames HF. 
     When the item lottery in the state K is won to get the “fever state,” a state L occurs in which the same type of item I as the item I 1  is finally displayed in a stationary state in the middle and rightmost possession frames HF. For example, in the state L, the item I 1  that is a mushroom is displayed in a stationary state in the leftmost possession frame HF, the item I 2  that is a mushroom is displayed in a stationary state in the middle possession frame HF, and the item I 3  that is a mushroom is displayed in a stationary state in the rightmost possession frame HF. Thus, in the state L, it is shown that as a result of the item lottery in the state K, the “fever state” caused by mushroom items in which the same mushroom item I is finally displayed in all the possession frames HF is won. As a result, the player object PO performs a race in the “fever state” caused by mushroom items. 
     Thus, in the first item lottery process example performed in the information processing system  1 , at least one is selected from items I included in a plurality of possession frames and is used, and therefore, an in-game effect can be obtained based on the type of the selected item I, and a possession frame in which that item I is displayed is changed to an empty frame E after the occurrence of the in-game effect. In addition, when the condition that all items I included in the plurality of possession frames are the same item is satisfied in an item lottery, the above in-game effect can provide a more advantageous in-game effect. 
     Next, a non-limiting example lottery table that sets probabilities of winning the “fever state” will be described with reference to  FIG. 14 . 
     In  FIG. 14 , the lottery table describes, the probability of winning the “fever state” is described for each combination of the number of possession frames HF that are an empty frame E and the type of an item I that causes the “fever state.” In the lottery table, the total probability of winning that is the sum of the probabilities of the items I, is also described. 
     For example, in the lottery table of  FIG. 14 , in an item lottery in which all the possession frames HF are an empty frame E and are in a rotation lottery state (all-frame rotation), the probability of winning using a carapace item is set to 10%, the probability of winning using a banana item is set to 10%, and the probability of winning using a mushroom item is set to 10%. In the lottery table, in an item lottery in which a carapace item I is finally displayed in one or two possession frames HF, and the remaining possession frames HF are an empty frame E (i.e., a possession frame HF that is an empty frame E and a possession frame HF in which a carapace item I is finally displayed coexists) and are in a rotation lottery state (non-all-frame rotation), the probability of winning using a carapace item is set to 10%, and the probability of winning using each of banana and mushroom items is set to 0%. Also, in the lottery table, in an item lottery in which a banana item I is finally displayed in one or two possession frames HF, and the remaining possession frames HF are an empty frame E (i.e., a possession frame HF that is an empty frame E and a possession frame HF in which a banana item I is finally displayed coexists) and are in a rotation lottery state (non-all-frame rotation), the probability of winning using a banana item is set to 10%, and the probability of winning using each of carapace and mushroom items is set to 0%. Also, in the lottery table, in an item lottery in which a mushroom item I is finally displayed in one or two possession frames HF, and the remaining possession frames HF are an empty frame E (i.e., a possession frame HF that is an empty frame E and a possession frame HF in which a mushroom item I is finally displayed coexists) and are in a rotation lottery state (non-all-frame rotation), the probability of winning using a mushroom item is set to 10%, and the probability of winning using each of carapace and banana items is set to 0%. 
     In the lottery table, the probability of winning using any item in all-frame rotation is set to 30%, and the probability of winning using any item in non-all-frame rotation is set to 10%. Thus, in the case where the lottery table is used, the probability of winning the “fever state” is highest when an item lottery is performed in which all the possession frames HF are an empty frame E. This is because the probability of winning an item lottery in any state is the same for all items. Therefore, by the use of such a lottery table, the strategy of leaving an item I that is desired by the user finally displayed in a possession frame HF and thereby increasing the winning probability using that item I can be prevented. 
     Note that the lottery table may be managed by the server  200 , and when a game is started in the information processing apparatus  3 , the lottery table may be transmitted from the server  200  to the information processing apparatus  3 . In this case, the server  200  may transmit a different lottery table, depending on the timing of gameplay, the level of the user of the information processing apparatus  3 , etc. The server  200  may set a different lottery table to be used, depending on the situation of a game. For example, the server  200  may set a different lottery table, depending on the number of laps in a race, the standing in a race, the type of a course or a race, the type of the player object PO, etc. As a non-limiting example, in the lottery table, the probability of winning the “fever state” may be set higher as a race is closer to the end or as the number of laps finished increases. As another non-limiting example, a different lottery table may be set, depending on equipment used in a race by the player object PO. For example, when the player object PO uses a special piece of equipment, the probability of winning the “fever state” may be set higher in a lottery table. 
     When the “fever state” is won, the effect of an item I causing the win as well as another effect may be given to the player object PO. As a non-limiting example, when the “fever state” caused by carapace items is won, the effect of continually firing a projectile carapace item IM as well as the effect of increasing or decreasing the traveling speed of the player object PO may be given to the player object PO during the fever period. As another non-limiting example, when the “fever state” caused by carapace items is won, the effect of continually firing a projectile carapace item IM as well as the defensive effect of keeping the player object PO traveling without an influence even when being attacked by the opponent object EO or colliding with other objects, may be given to the player object PO during the fever period. As a non-limiting example, even when a projectile carapace item IM fired by the player object PO is returned to the player object PO itself, the player object PO repels or avoids the projectile carapace item IM so that the traveling of the player object PO is not affected, and therefore, in the “fever state,” the user can fire a projectile carapace item IM without caring an influence on the player object PO itself. 
     A special item (e.g., a “lucky  7 ” item) may be set which provides the effects of a plurality of types of items I. For example, in the above item lottery, when the special item is finally displayed in all the possession frames HF and the “fever state” caused by the special items is won, the effect of successively giving the effects of a plurality of items appearing in the game is given to the player object PO during the fever period. Meanwhile, when the item lottery is lost with the special item existing in at least one possession frame HF, the special item is removed from that possession frame HF without getting the effect of the special item that would be obtained when used alone, and the possession frame HF is changed to an empty frame E. 
     In the non-limiting example embodiment, the player object PO can acquire a new item I only if there is a possession frame HF that is an empty frame E. Alternatively, even when there is no possession frame HF that is an empty frame E, a new item I may be able to be acquired. In this case, even when there is no possession frame HF that is an empty frame E, an item lottery can be performed, and the possession frames HF in which an item I is being displayed are put into the rotation lottery state. When an empty frame E and a frame in which an item I is being displayed coexist among the possession frames HF, not only the empty frame E but also the possession frame HF in which an item I is being displayed may be put into the rotation lottery state in an item lottery. When a possession frame HF in which an item I is being displayed is put into the rotation lottery state and an item lottery is performed, the possession frame HF may not be changed to an empty frame E after the item I is used. 
     In the above non-limiting example embodiment, the “fever state” is won if all possession frames HF have the same item I. Alternatively, the condition under which the “fever state” is won using items I may be other combinational conditions. As a non-limiting example, in the case where there are four possession frames HF, the “fever state” is won if at least three of the possession frames HF have the same item I. As another non-limiting example, the “fever state” may be won if three possession frames HF have a specific combination of items I (e.g., mushroom-carapace-banana). 
     After the “fever state” is won, the player object PO may be put into the “fever state” immediately or a predetermined period of time after the user is notified of the win. Alternatively, after the “fever state” is won, the player object PO may be put into the “fever state” in response to the user&#39;s predetermined operation. 
     The probability of winning the “fever state” and the types of items I that are displayed in a stationary state in possession frames HF may be controlled according to a rule that is different from the control performed based on the lottery table. For example, the probability of winning the “fever state” and the types of items I that are displayed in a stationary state in possession frames HF may be controlled randomly or based on the timing at which an item box IB is opened, or such that items I are displayed in a stationary state in possession frames HF in a predetermined order. 
     Next, a second item lottery process example that is performed in the information processing system  1  will be outlined with reference to  FIGS. 15-18 . In the second item lottery process example, an item lottery can be performed without opening an item box IB provided in a race if a predetermined condition is satisfied. Note that  FIG. 15  is a diagram showing a non-limiting example game image displayed on the display unit  35  of the information processing apparatus  3 .  FIG. 16  is a diagram showing a non-limiting example game image displayed on the display unit  35  of the information processing apparatus  3 .  FIG. 17  is a diagram showing a non-limiting example state transition of items I possessed in possession frames HF and an item lottery icon AB.  FIG. 18  is a diagram showing a non-limiting example game image displayed on the display unit  35  of the information processing apparatus  3 . 
     As in  FIGS. 4 and 5 , in  FIG. 15 , the display unit  35  of the information processing apparatus  3  displays a game image corresponding to a game played in the information processing apparatus  3 . As a non-limiting example,  FIG. 15  shows a scene in which the player object PO performs a racing game. For example, in the game, the player object PO is sitting on and driving a cart on a course provided in a virtual world. If a predetermined condition is satisfied when the player object PO is traveling, an item lottery icon AB appears instead of the possession frames HF. 
     The item lottery icon AB functions as an operation instruction button that is selected and executed by the user&#39;s touch operation. Currency amount information M that indicates the amount of virtual currency that is consumed when the item lottery icon AB is selected and executed is provided near the item lottery icon AB. In the non-limiting example of  FIG. 15 , the currency amount information M indicates that when the item lottery icon AB is used, a piece of star-shaped virtual currency that can be acquired by the user by payment is consumed. Note that the item lottery icon AB and the currency amount information M appear if all the possession frames HF are an empty frame E, and do not appear if the number of times of use exceeds a limit (e.g., once a race) due to consumption or if the user does not have enough virtual currency to use the item lottery icon AB. For example, when the item lottery icon AB is used by a touch operation (e.g., a tap operation) on the item lottery icon AB displayed on the touch panel, an item lottery event for acquiring a new item I is started. Note that the state in which the item lottery icon AB does not appear may be such that the item lottery icon AB is not displayed on the display screen, or such that the item lottery icon AB may be displayed grayed-out or translucent. Even in a state in which the item lottery icon AB is not allowed to be selected, the item lottery icon AB may be displayed on the display screen. In this case, even when the user performs an operation of selecting the item lottery icon AB, the item lottery icon AB provokes no response. 
     As shown in  FIG. 16 , when the item lottery icon AB is used, the possession frames HF appear instead of the item lottery icon AB and the currency amount information M. As in the first item lottery process example, a rotating display item IR indicating the rotation lottery display state is displayed in all the possession frames HF, and thereafter, any item I is displayed in a stationary state in each frame, indicating that the items I have finally been displayed in a stationary state and acquired in a lottery. 
     Even in an item lottery triggered by using the item lottery icon AB, items I that are displayed in a stationary state in possession frames HF are finally acquired by the player object PO through the lottery, and after the acquisition, the player object PO can use the acquired items one by one in a predetermined order using the above operation method. The player object PO can obtain an advantageous effect to progression of the game using the items I. 
     Even in an item lottery triggered by using the item lottery icon AB, when the same item I is finally displayed in all the possession frames HF through the lottery, the “fever state” is won and the player object PO can obtain a more advantageous effect to progression of a race. As in the first item lottery process example, when the player object PO wins the “fever state,” an item causing the “fever state” can be continually used only during a predetermined fever period. 
     Thus, in an item lottery triggered by using the item lottery icon AB, a new item I can be acquired or the “fever state” can be won, as in an item lottery triggered by opening an item box IB provided on the course. Therefore, the user can start a new item lottery whenever the item lottery icon AB appears, in addition to the situation where an item box IB is placed on the course. Note that an item lottery triggered by using the item lottery icon AB and an item lottery triggered by opening an item box IB may include more elements different therebetween. 
     As a first non-limiting example, a period of time for which an item lottery triggered by using the item lottery icon AB is performed (a rotation lottery event of an item I is performed) may be set shorter than a period of time for which an item lottery triggered by opening an item box IB is performed. As a result, when the item lottery icon AB is used, the time it takes for the player object PO to obtain an effect provided by acquiring a new item I or winning the “fever state” can be reduced, and as a result, the player object PO can obtain an advantageous effect earlier. 
     As a second example, the probability of winning an item lottery triggered by using the item lottery icon AB to get the “fever state” may be set higher than the probability of winning an item lottery triggered by opening an item box IB to get the “fever state.” As a result, when the item lottery icon AB is used, the probability that the player object PO obtains an effect provided by the “fever state” is increased, and therefore, the possibility that the player object PO can obtain an advantageous effect is increased. Note that the magnitude of an increase in the probability of winning the “fever state” may be changed, depending on the amount of virtual currency consumed when the item lottery icon AB is selected and executed. As a non-limiting example, as the amount of virtual currency consumed when the item lottery icon AB is selected and executed increases, the probability may be increased. In this case, as the number of times of selection and execution of the item lottery icon AB in a race increases, the amount of virtual currency consumed by the execution may be increased, and the probability may be increased with an increase in the consumed virtual currency amount. Compared to when an item lottery triggered by opening an item box IB is won to get the “fever state,” the probability of winning using an item having a higher effect may be increased when an item lottery triggered by using the item lottery icon AB is won to get the “fever state.” 
     Next, a non-limiting example progression of a game in which a lottery for a new item I is triggered by using the item lottery icon AB will be described with reference to  FIG. 17 . 
     In  FIG. 17 , in a state M that is a non-limiting example state of the possession frames HF, all items I displayed in the possession frames HF are different, i.e., a loss state. When all the items I 1 -I 3  displayed in the possession frames HF in the state M have been used, a state N occurs in which all the possession frames HF are an empty frame E. If all the possession frames HF are an empty frame E, one of conditions for causing the item lottery icon AB is satisfied. 
     In the state N, if the number of times of selection and execution of the item lottery icon AB has not reached a limit, and the user possesses virtual currency that is consumed when the execution is performed, a state O occurs in which the item lottery icon AB and the currency amount information M appear instead of the possession frames HF. In this case, when a touch operation is performed on the item lottery icon AB displayed on the touch panel, control proceeds to the process of selecting and executing the item lottery icon AB, and an item lottery is performed for all the possession frames HF. As a result, a state P occurs in which the rotation lottery display of a rotating display item IR is performed for all the possession frames HF. 
     When the item lottery in the state P is won to get the “fever state,” a state Q occurs in which the same item I is displayed in a stationary state in all the possession frames HF. For example, in the state Q, a mushroom item I 1  is displayed in a stationary state in the leftmost possession frame HF, a mushroom item I 2  is displayed in a stationary state in the middle possession frame HF, and a mushroom item I 3  is displayed in a stationary state in the rightmost possession frame HF. Thus, as a result of the item lottery in the state P, it is shown in the state Q that the same mushroom item I is finally displayed in all the possession frames HF, and therefore, the “fever state” caused by mushroom items is won. As a result, the player object PO can perform a race in the “fever state” caused by mushroom items. 
     When a predetermined fever period has passed since the occurrence of the “fever state” caused by mushroom items, the “fever state” of the player object PO ends, and a state R occurs in which all the possession frames HF are an empty frame E. When all the possession frames HF are thus an empty frame E, an item lottery can be performed for all the possession frames HF again. Note that in the state R in which all the possession frames HF are an empty frame E, if the number of times of selection and execution of the item lottery icon AB has not yet reached a limit, and the user possesses virtual currency that can be consumed in the execution, the state that the item lottery icon AB and the currency amount information M appear instead of the possession frames HF may occur. If the above conditions are not satisfied, the item lottery icon AB does not appear again in the race. 
     Next, a non-limiting example of virtual currency consumed by selection and execution of the item lottery icon AB will be described. For example, in the non-limiting example embodiment, star-shaped virtual currency can be purchased by the user using real currency, i.e., payment. For example, when the user has performed a process of purchasing star-shaped virtual currency by paying real currency using the information processing apparatus  3 , information about payment for the purchase is transmitted to the server  200 , and a predetermined authentication process is performed before the payment is settled between the server  200  and the user. When the information processing apparatus  3  is notified of the settlement for the purchase of the star-shaped virtual currency by the server  200 , the information processing apparatus  3  adds the purchased star-shaped virtual currency to the user&#39;s possession. Note that star-shaped virtual currency managed in the user&#39;s possession may be usable in other games. As used herein, the term “purchase” refers to a situation in which virtual currency can be acquired by paying real currency. Specifically, when a user has to pay to use software for a game, or a user has to play a game itself, or a user has to play to use a predetermined action in a game, etc., then if the user acquires virtual currency by paying real currency, it can be considered that the user acquires virtual currency by purchase. Needless to say, when software for performing a game is free, or playing a game itself is free, or a predetermined action in a game is free, etc., then if a user acquires virtual currency by paying real currency, it can be considered that the user acquires virtual currency by purchase. The above purchase using real currency may be settled by a means previously purchased by a user, or delayed payment. For example, virtual currency may be purchased using a prepaid card previously purchased by a user, or a credit card, which a user uses to pay later. 
     Star-shaped virtual currency purchased by payment as described above can be exchanged for various things in the game. For example, in a purchase scene which can be viewed before the start of the racing game or after the end of the racing game, i.e., a game scene different from those appearing during a race, pieces of equipment used in a race, in-game coins, etc., can be purchased using star-shaped virtual currency. For example, as shown in  FIG. 18 , in a purchase screen displayed in the purchase scene, displayed are purchase buttons B 1  that can be used to purchase in-game coins using star-shaped virtual currency, purchase buttons B 2  that can be used to purchase a piece of equipment for use in a race using in-game coins, and a purchase button B 3  that can be used to purchase star-shaped virtual currency by payment. Note that a first game scene is a scene in which game contents can be obtained or enhanced, and the obtained and/or enhanced game contents can be used in a second game scene. After game contents can be obtained or enhanced in the first game scene, a transition to the second game scene can occur, and after the second game scene, a transition back to the first game scene can occur. 
     Specifically, the purchase buttons B 1  include a button for exchanging 10 pieces of star-shaped virtual currency for 100 in-game coins, a button for exchanging 100 pieces of star-shaped virtual currency for 1200 in-game coins, and a button for exchanging 1000 pieces of star-shaped virtual currency for 15000 in-game coins. Here, in-game coins function as a parameter that can be acquired as a consideration for an achievement in the racing game, or can be acquired by acquiring a predetermined item in the racing game. Typically, in-game coins can be acquired and used in the racing game. In-game coins can also be purchased with (or exchanged for) virtual currency possessed by the user by selecting and executing a purchase button B 1  desired by the user in the purchase screen. 
     The purchase buttons B 2  include a button for purchasing first equipment that can be used in the race by consuming 1000 in-game coins, a button for purchasing second equipment that can be used in the race by consuming 200 in-game coins, a button for purchasing third equipment that can be used in the race by consuming 500 in-game coins, and a button for purchasing fourth equipment that can be used in the race by consuming 100 in-game coins. Here, a piece of equipment that can be used in the race is such that when the player object PO participates in the race using the equipment, a specific ability of the equipment is given to the player object PO, and the player object PO can acquire an in-game effect advantageous to progression of the race using the equipment. As a non-limiting example, by the use of a piece of equipment, the player object PO can acquire a specific ability of the equipment such as increasing the traveling speed or acceleration, improving steering properties, increasing places where traveling is allowed, or enhancing defensive power. The player object PO can continue to use purchased equipment in a plurality of races, and therefore, as long as the equipment is effective, the equipment functions as an item that gives a continual in-game effect to the player object PO. Meanwhile, even if the possession of an item I can be carried over to another race, the in-game effect caused by the use of the item I or the in-game effect caused by the “fever state” is limited to a partial period of time in a race in which the effect occurs, and is not continued into another race, and therefore, equipment can be said to be an item that gives a temporary in-game effect to the player object PO. 
     As can be seen from the purchase buttons B 1  and B 2 , after exchanging star-shaped virtual currency for in-game coins, the user can purchase equipment using the in-game coins. Therefore, the user can purchase equipment using star-shaped virtual currency through in-game coins. Although, in the above purchase screen example, star-shaped virtual currency needs to be once exchanged for in-game coins in order to purchase equipment, equipment may be purchased directly using star-shaped virtual currency without exchanging for in-game coins. In some games in which star-shaped virtual currency is not set, in-game coins may be purchasable directly by payment. In this case, in such games, star-shaped virtual currency does not exist, and only in-game coins exist, and therefore, equipment may be purchasable by the use of in-game coins, and a predetermined number of (e.g., 1000) of in-game coins may be consumed when the item lottery icon AB is used. In the case where only in-game coins exist, the in-game coins may not necessarily be purchasable directly by payment. 
     In the above example game, when the item lottery icon AB is selected and executed, star-shaped virtual currency is consumed. Alternatively, in-game coins that can be exchanged for star-shaped virtual currency in the purchase screen may be consumed upon the execution. Thus, even in the case where in-game coins are consumed when the item lottery icon AB is selected and executed, after star-shaped virtual currency is once exchanged for in-game coins, the item lottery icon AB can be executed using the in-game coins. Therefore, it can be said that star-shaped virtual currency can be used to execute the item lottery icon AB. 
     In the purchase screen, an “item lottery icon AB execution right” that allows the item lottery icon AB to be selected and executed may be purchasable by the use of star-shaped virtual currency or in-game coins exchangeable for star-shaped virtual currency. For example, if the user has purchased and possesses the “item lottery icon AB execution right,” then when the item lottery icon AB appears, the user can select and execute the item lottery icon AB by using and consuming the “item lottery icon AB execution right.” Thus, even in the case where the “item lottery icon AB execution right” is consumed when the item lottery icon AB is selected and executed, after star-shaped virtual currency or in-game coins are once exchanged for the “item lottery icon AB execution right,” the item lottery icon AB can be executed using the “item lottery icon AB execution right.” Therefore, it can be said that star-shaped virtual currency can be used to execute the item lottery icon AB. 
     Thus, in the second item lottery process example performed in the information processing system  1 , in a purchase scene in which in-game coins, equipment, etc., can be purchased, when equipment is purchased using star-shaped virtual currency or in-game coins changed from the virtual currency, the amount of possessed virtual currency is reduced, and the player object PO can obtain an effect of the equipment that continues to be effective in a plurality of races. When the player object PO comes into contact with an item box IB disposed on the course in a race, the player object PO can obtain a temporary effect that is effective in that race by the use of an item I. Furthermore, when the item lottery icon AB is selected and executed in a race, the amount of possessed virtual currency is consumed and reduced by the execution, and the player object PO can obtain the above temporary effect that is effective in that race by the use of an item I or a temporary effect of winning the “fever state”. Therefore, star-shaped virtual currency and in-game coins function as items that give various effects to the player object PO, and therefore, the user can be more motivated to acquire star-shaped virtual currency or in-game coins. 
     Note that in the above non-limiting example embodiment, only when all the possession frames HF are an empty frame E, the item lottery icon AB appears. Alternatively, the item lottery icon AB may appear even when none of the possession frames HF is an empty frame E or when a portion of the possession frames HF are an empty frame E. In this case, even when none of the possession frames HF is an empty frame E or when a portion of the possession frames HF are an empty frame E, an item lottery can be triggered by selecting the item lottery icon AB, and a possession frame HF in which an item I is being displayed is also put into the rotation lottery state. When an item lottery is performed by selecting the item lottery icon AB in a situation that an empty frame E and a frame in which an item I is being displayed coexist among the possession frames HF, the empty frame E as well as the possession frame HF in which an item I is being displayed may be put into the rotation lottery state. 
     In the above description, when the player object PO comes into contact with an item box IB disposed on the course in a race, the player object PO can obtain a temporary effect that is effective in that race by the use of an item I. Alternatively, the temporary effect may be obtained without such a contact with an item box IB. For example, instead of a lottery event for a new item I that is triggered when the player object PO comes into contact with an item box IB, a lottery event for a new item I may be automatically performed at predetermined intervals. In this case, by selecting the item lottery icon AB, a new item I may be allowed to be acquired through a lottery even during the predetermined interval. 
     The probability of winning the “fever state” in the case of selection of the item lottery icon AB and the type of an item I that is displayed in a stationary state in a possession frame HF may be controlled according to a rule different from that for the control performed based on the lottery table. For example, the probability of winning the “fever state” in the case of selection of the item lottery icon AB and the type of an item I that is displayed in a stationary state in a possession frame HF may be controlled randomly or based on the timing of selection of the item lottery icon AB, or such that items I are displayed in a stationary state in possession frames HF in a predetermined order. 
     The number of possession frames HF may be changed, depending on the type of the player object PO. As a non-limiting example, the number of possession frames HF may be changed, depending on a relationship between the player object PO and a course on which the player object PO travels. Three possession frames HF may be displayed for a course having a good relationship with the player object PO, and one possession frame HF may be displayed for a course having a bad relationship with the player object PO. When a gameplay is performed using a course for which a single possession frame HF is displayed, the player object PO can simultaneously have a smaller number of items I, and the “fever state” caused by all the possession frames HF having the same item I does not occur, and therefore, the user is in a disadvantageous condition. Note that even in the case where a course has a bad relationship and a single possession frame HF is displayed, three possession frames HF may appear and a lottery event may be performed for new items I when the item lottery icon AB is selected. In the case where the number of displayed possession frames HF is thus changed, depending on the relationship between the player object PO and a course, the user is motivated to select the type of a player object PO to be used. 
     Next, processes performed in the information processing apparatus  3  will be described in detail. Firstly, main data used in processes performed in the information processing apparatus  3  will be described with reference to  FIG. 19 . Note that  FIG. 19  is a diagram showing non-limiting example main data and programs stored in the storage unit  32  of the information processing apparatus  3 . 
     As shown in  FIG. 19 , the storage unit  32  stores, in a data storage region, operation data Da, transmission data Db, reception data Dc, user possession data Dd, lottery table data De, current touch input coordinate data Df, touch path coordinate data Dg, first reference coordinate data Dh, second reference coordinate data Di, leftward/rightward component data Dj, steering wheel angle data Dk, input length data Dm, input vector data Dn, determination region data Dp, firing direction data Dq, possession frame data Dr, first lottery flag data Ds, second lottery flag data Dt, winning flag data Du, lottery number-of-times data Dv, player object action data Dw, opponent object action data Dx, item position data Dy, and image data Dz, etc. Note that the storage unit  32  stores, in addition to data contained in the information of  FIG. 19 , data, etc., data required in the process such as data used in an executed application. The storage unit  32  also stores, in a program storage region, various programs Pa including a communication program and an information processing program (game program). 
     The operation data Da indicates operation information about the user&#39;s operation on the information processing apparatus  3 . For example, operation data indicating an operation performed on the input unit  34  including the touch panel is acquired at time intervals that are a unit process time (e.g., 1/60 sec) of the information processing apparatus  3 , and the operation data Da is updated with the acquired operation data. 
     The transmission data Db is stored as data to be transmitted to the server  200 . The reception data Dc has been received from the server  200 . 
     The user possession data Dd indicates virtual currency, in-game coins, equipment, characters, items, an experience point, a play level, a user ID, etc., which are possessed by the user and the player object PO operated by the user, and are managed by the server  200 , are received from the server  200 , and are set before the start of the game. 
     The lottery table data De indicates the probability of winning the “fever state” for each type of item I, which is set based on the number of empty frames E, timing, the state of the player object PO, etc. For example, the lottery table data De is managed by the server  200 , is received from the server  200  and is set before the start of the game. 
     The current touch input coordinate data Df indicates the current touch position coordinate point T of a touch operation at a current time on the input unit  34  (touch panel). The touch path coordinate data Dg indicates the records (touch path coordinates) of touch input coordinate points from the time when the touch panel is first touched to the current time. The first reference coordinate data Dh indicates a touch input coordinate point where the touch panel is first touched, and indicates a reference coordinate point (the reference coordinate point R 0 ) that is used to calculate the leftward/rightward component of a swipe input. The second reference coordinate data Di indicates a touch input coordinate point that moves on a touch path in a manner that satisfies a predetermined condition, and indicates a reference coordinate point (the reference coordinate point Rm) that is used to calculate the upward/downward component of a swipe input. 
     The leftward/rightward component data Dj indicates the leftward/rightward component of a swipe input performed by the user. The steering wheel angle data Dk indicates a steering wheel angle of the player object PO that is calculated based on the leftward/rightward component of a swipe input. 
     The input length data Dm indicates the length of a path of touch positions input by the user. The input vector data Dn indicates a vector FD from the reference coordinate point Rm toward the current touch position coordinate point T. 
     The determination region data Dp indicates the determination regions UA and LA for determining the upward or downward direction of a swipe input. The firing direction data Dq indicates the direction of a projectile item IM fired by the player object PO. 
     The possession frame data Dr indicates the object ID of an item I disposed in each possession frame HF. When a possession frame HF is an empty frame E, data indicating an empty frame E is set for that possession frame HF. 
     The first lottery flag data Ds indicates a first lottery flag that is set on for a period of time that an item lottery triggered by the player object PO opening an item box IB is being performed. The second lottery flag data Dt indicates a second lottery flag that is set on for a period of time that an item lottery triggered by the user selecting and executing the item lottery icon AB is being performed. The winning flag data Du indicates a winning flag that is set on for a period of time that the “fever state” is being continued. The lottery number-of-times data Dv indicates the number of item lotteries that have been performed by selecting and executing the item lottery icon AB. 
     The player object action data Dw indicates an action of the player object PO, and includes the position, speed, orientation, number of laps, standing, etc., of the player object PO in a race. The opponent object action data Dx indicates an action of the opponent object EO, and includes the position, speed, orientation, number of laps, standing, etc., of the opponent object EO in a race. The item position data Dy indicates the position of an icon I (the ready-to-use item IP) disposed at the ready-to-use position and the position of a fired icon I (the projectile item IM). 
     The image data Dz is data for displaying a game image (e.g., an image of the player object PO, an image of the opponent object EO, an image of an item I, an image of a possession frame HF, an image of the item lottery icon AB, an image of another virtual object, a field image of a course, etc., a background image, etc.) on the display unit  35  of the information processing apparatus  3  in the game. 
     Next, processes performed in the information processing apparatus  3  will be described in detail with reference to  FIGS. 20-24 . Note that  FIG. 20  is a flowchart showing a non-limiting example process executed in the information processing apparatus  3 .  FIG. 21  is a subroutine showing a detailed example of an operation determination process in step S 106  of  FIG. 20 .  FIG. 22  is a subroutine showing a detailed example of a first item lottery process in step S 107  of  FIG. 20 .  FIG. 23  is a subroutine showing a detailed example of a second item lottery process in step S 108  of  FIG. 20 .  FIG. 24  is a subroutine showing a detailed example of a purchase process in step S 116  of  FIG. 20 . Here, of the processes of the information processing system  1  in the flowcharts of  FIGS. 20-24 , game processes involved in an operation on the player object PO, an item lottery, and a purchase process that is performed on an occasion other than a race, will be mainly described as a non-limiting example, and other processes that are not directly involved with these processes will not be described in detail. In  FIGS. 20-24 , each step executed by the control unit  31  is abbreviated to “S.” 
     In the non-limiting example embodiment, steps shown in  FIGS. 20-24  are performed by the control unit  31  (CPU) executing a communication program or game program stored in the program storage unit  33 . Note that the processes of  FIGS. 20-24  are started with any appropriate timing. At this time, all or a portion of the communication program or game program is read from the storage unit  32  with appropriate timing, and is executed by the control unit  31 . Thus, the processes of  FIGS. 20-24  are started. Note that the communication program and the game program are assumed to be previously stored in the program storage unit  33 . In another non-limiting example embodiment, the communication program and the game program may be obtained from a storage medium removably attached to the information processing apparatus  3 , and stored in the storage unit  32 , or may be obtained from another apparatus through a network, such as the Internet, and stored in the storage unit  32 . 
     The steps of the flowcharts of  FIGS. 20-24  are merely illustrative, and if a similar result is obtained, the order in which the steps are performed may be changed, and another step may be executed in addition to or instead of each step. Although, in the non-limiting example embodiment, it is assumed that each step of the flowcharts is executed by the control unit  31 , all or a portion of the steps of the flowcharts may be executed by a processor other than the CPU of the control unit  31  or a dedicated circuit. 
     In  FIG. 20 , the control unit  31  performs a communication process (step S 101 ), and proceeds to the next step. For example, the control unit  31  transmits transmission data (e.g., data for user authentication (e.g., data indicating the user&#39;s ID)) stored in the transmission data Db to the server  200  through the network  100 . The control unit  31  receives data from the server  200  through the network  100 , and updates the reception data Dc using the received data. As a non-limiting example, when a game is played along with another information processing apparatus  3  or in only the information processing apparatus  3  itself, the control unit  31  exchanges data for playing the game with the server  200 , as appropriate, in step S 101 . 
     Next, the control unit  31  sets initial settings (step S 102 ), and proceeds to the next step. For example, the control unit  31  initially sets parameters for use in the subsequent steps. The control unit  31  also initially sets the user possession data Dd based on contents such as a virtual object and an item that are currently possessed by the player object PO. For example, in step S 101 , the control unit  31  receives, from the server  200 , data possessed by the user, data related to the player object PO operated by the user (e.g., data related to virtual currency, in-game coins, equipment, characters, items, an experience point, a play level, etc.), data for progression of a racing game described below (e.g., lottery table data), etc. Thereafter, the control unit  31  initially sets the user possession data Dd and the lottery table data De based on the data received from the server  200  and the data stored in the information processing apparatus  3 . In steps S 101  and S 102 , the amounts of virtual currency and in-game coins possessed by the user, a lottery table for performing an item lottery, etc., are initially set. 
     Next, the control unit  31  acquires operation data from the input unit  34  and updates the operation data Da (step S 103 ), and proceeds to the next step. 
     Next, the control unit  31  determines whether or not to start a racing game (step S 104 ). For example, if the user has performed an operation of starting a racing game or a predetermined start condition for starting the racing game is satisfied, the result of the determination by the control unit  31  of step S 104  is positive. If the control unit  31  determines to start a racing game, the control unit  31  proceeds to step S 105 . Otherwise, i.e., if the control unit  31  determines not to start a racing game, the control unit  31  proceeds to step S 115 . 
     In step S 105 , the control unit  31  obtains operation data from the input unit  34  and updates the operation data Da, and proceeds to the next step. 
     Next, the control unit  31  performs an operation determination process (step S 106 ), and proceeds to step S 107 . The operation determination process performed in step S 106  will now be described with reference to  FIG. 21 . 
     In  FIG. 21 , the control unit  31  updates a current touch position coordinate point based on the most recent operation data obtained in step S 105  (step S 121 ), and proceeds to the next step. For example, the control unit  31  defines, in the display screen of the display unit  35 , a display screen coordinate system in which an X-axis extending in the leftward/rightward direction of the display screen (the rightward direction is the positive direction of the X-axis) and a Y-axis extending in the upward/downward direction of the display screen (the upward direction is the positive direction of the Y-axis) are set. The control unit  31  obtains, from the most recent operation data obtained in step S 105 , a touch input coordinate point of the display screen coordinate system at which a touch operation is being performed on the touch panel of the information processing apparatus  3 , as a current touch input coordinate point T, and updates the current touch input coordinate data Df using the current touch input coordinate point T. Note that if the most recent operation data obtained in step S 105  does not contain a touch input coordinate point at which a touch operation is being performed on the touch panel, the control unit  31  determines that the user has released a touch from the touch panel, and updates the current touch input coordinate data Df using data indicating the release of a touch. 
     Next, the control unit  31  adds the current touch input coordinate point T updated in step S 121  to touch path coordinate points (step S 122 ), and proceeds to the next step. For example, the control unit  31  adds the current touch input coordinate point T updated in step S 121  to touch path coordinate points indicated by the touch path coordinate data Dg, and updates the touch path coordinate data Dg using the touch path coordinate points after the addition. Note that if the current touch input coordinate data Df indicates that a touch has been released, the control unit  31  does not update the touch path coordinate data Dg, and proceeds to the next step. 
     Next, the control unit  31  determines whether or not the touch panel of the information processing apparatus  3  has been changed to a no-touch state to an initial-touch state (step S 123 ). Thereafter, if the touch panel has been changed from the no-touch state to the initial-touch state, the control unit  31  proceeds to step S 124 . Otherwise, i.e., if the touch panel has not been changed from the no-touch state to the initial-touch state (e.g., the touch panel is not touched or a touch operation is continued after an initial touch), the control unit  31  proceeds to step S 125 . 
     In step S 124 , the control unit  31  sets a first reference coordinate point and a second reference coordinate point, and proceeds to step S 125 . For example, the control unit  31  obtains the current touch input coordinate point T updated in step S 121  by referring to the current touch input coordinate data Df, and sets the current touch input coordinate point T as a first reference coordinate point R 0  and a second reference coordinate point Rm of the display screen coordinate system. Thereafter, the control unit  31  updates the first reference coordinate point data Dh using the set first reference coordinate point R 0 , and updates the second reference coordinate point data Di using the set second reference coordinate point Rm. 
     In step S 125 , the control unit  31  calculates the leftward/rightward component of an input of swiping the touch panel, and proceeds to the next step. For example, the control unit  31  obtains the reference coordinate point R 0 (X 0 , Y 0 ) and the current touch position coordinate point T(Xt, Yt) in the display screen coordinate system by referring to the first reference coordinate point data Dh and the current touch input coordinate data Df. Thereafter, the control unit  31  calculates Xt−X 0  as the magnitude of the leftward/rightward component (X-axis-direction component) of the swipe input in the display screen, and updates the leftward/rightward component data Dj using the calculated Xt−X 0 . 
     Next, the control unit  31  calculates a steering wheel angle of the player object PO (step S 126 ), and proceeds to the next step. For example, if the leftward/rightward component Xt−X 0  calculated in step S 125  has a positive value, the control unit  31  calculates a rightward steering wheel angle corresponding to the absolute value of Xt−X 0 , and updates the steering wheel angle data Dk using the steering wheel angle. If the leftward/rightward component Xt−X 0  calculated in step S 125  has a negative value, the control unit  31  calculates a leftward steering wheel angle corresponding to the absolute value of Xt−X 0 , and updates the steering wheel angle data Dk using the steering wheel angle. Note that when a touch is released from the touch panel, the control unit  31  changes and returns the steering wheel angle to the straight-ahead position at a predetermined rate, and updates the steering wheel angle data Dk. 
     Next, the control unit  31  calculates an input length between the second reference coordinate point Rm and the current touch input coordinate point T (step S 127 ), and proceeds to the next step. For example, the control unit  31  calculates an input length along the touch input path between the second reference coordinate point Rm and the current touch position coordinate point T by referring to the current touch input coordinate data Df, the touch path coordinate data Dg, and the second reference coordinate point data Di, and updates the input length data Dm using the input length. 
     Next, the control unit  31  determines whether or not the input length calculated in step S 127  is greater than a predetermined threshold L (step S 128 ). If the input length is greater than the predetermined threshold L, the control unit  31  proceeds to step S 129 . Otherwise, i.e., if the input length is smaller than or equal to the predetermined threshold L, the control unit  31  proceeds to step S 130 . 
     In step S 129 , the control unit  31  moves the second reference coordinate point Rm such that the input length becomes smaller than or equal to the threshold L, and proceeds to step S 130 . For example, in order to reduce the input length calculated in step S 127  at a predetermined rate to a length smaller than or equal to the threshold L, the control unit  31  sequentially deletes records of touch position coordinate points T that are beyond the threshold L based on the predetermined rate, and after the deletion process, sets the position of the most previous touch position coordinate point T as the second reference coordinate point Rm. As a result, the control unit  31  moves the second reference coordinate point Rm along the touch input path in the direction of the current touch position coordinate point T, and updates the second reference coordinate point data Di using the moved second reference coordinate point Rm. 
     In step S 130 , the control unit  31  calculates the input vector FD, and proceeds to the next step. For example, the control unit  31  calculates the input vector FD from the second reference coordinate point Rm to the current touch position coordinate point T in the display screen coordinate system by referring to the current touch input coordinate data Df and the second reference coordinate point data Di, and updates the input vector data Dn using the input vector FD. 
     Next, the control unit  31  determines whether or not the length of the input vector FD is greater than or equal to a predetermined length and the direction of the input vector FD is within a predetermined determination region (step S 131 ). If the length of the input vector FD is greater than or equal to the predetermined length and the direction of the input vector FD is within the determination region, the control unit  31  proceeds to step S 132 . Otherwise, i.e., if the control unit  31  determines that the length of the input vector FD is not greater than or equal to the predetermined length or the direction of the input vector FD is not within the determination region, the control unit  31  deletes the firing direction indicated by the firing direction data Dq, and proceeds to step S 133 . For example, the control unit  31  obtains the forward-direction determination region UA that is a predetermined angle range around the positive direction of the Y-axis as a center thereof, and the backward-direction determination region LA that is a predetermined angle range around the negative direction of the Y-axis as a center thereof, by referring to the determination region data Dp. If the length of the input vector FD calculated in step S 130  is greater than or equal to the predetermined length, and the direction of the input vector FD is within the forward-direction determination region UA or the backward-direction determination region LA, the result of the determination by the control unit  31  in step S 131  is positive. 
     In step S 132 , the control unit  31  sets the firing direction, and proceeds to step S 133 . For example, if the direction of the input vector FD calculated in step S 130  is within the forward-direction determination region UA, the control unit  31  sets the direct forward direction of the player object PO as the firing direction, and updates the firing direction data Dq using the firing direction. If the direction of the input vector FD calculated in step S 130  is within the backward-direction determination region LA, the control unit  31  sets the direct backward direction of the player object PO as the firing direction, and updates the firing direction data Dq using the firing direction. Note that the control unit  31  may set, as the firing direction, a direction that deviates from the direct forward direction or direct backward direction of the player object PO by the difference in angle between the Y-axis direction and the direction of the input vector FD. 
     In step S 133 , the control unit  31  determines whether or not the touch operation performed on the touch panel of the information processing apparatus  3  has been changed to the no-touch state. If the touch operation performed on the touch panel has been changed to the no-touch state, the control unit  31  proceeds to step S 134 . Otherwise, i.e., if the touch operation performed on the touch panel has not been changed to the no-touch state (e.g., a touch operation is not being continued after a touch is released, the touch panel is first touched, and a touch operation is being continued after the touch panel is first touched), the control unit  31  ends the process of the subroutine. 
     In step S 134 , the control unit  31  deletes the first reference coordinate point R 0 , the second reference coordinate point Rm, and the touch path coordinate points, and ends the process of the subroutine. For example, the control unit  31  deletes the first reference coordinate point R 0  indicated by the first reference coordinate point data Dh, the second reference coordinate point Rm indicated by the second reference coordinate point data Di, and the touch path coordinate points indicated by the touch path coordinate data Dg. 
     Referring back to  FIG. 20 , after the operation determination process in step S 106 , the control unit  31  performs the first item lottery process (step S 107 ), and proceeds to step S 108 . The first item lottery process performed in step S 107  will now be described with reference to  FIG. 22 . 
     In  FIG. 22 , the control unit  31  determines whether or not the possession frames HF include an empty frame E (step S 141 ). For example, the control unit  31  obtains an object ID set for each possession frame HF by referring to the possession frame data Dr, and if there is data indicating that at least one of the possession frames HF is an empty frame E, the result of the determination by the control unit  31  in step S 141  is positive. If the possession frames HF include an empty frame E, the control unit  31  proceeds to step S 142 . Otherwise, i.e., if the possession frames HF include no empty frame E, that is, the object ID of an item I is set in all the possession frames HF, the control unit  31  proceeds to step S 145 . 
     In step S 142 , the control unit  31  determines whether or not the player object PO has passed by or through an item box IB disposed on the course and thereby opened the item box IB. For example, if the control unit  31  determines that the player object PO&#39;s action of passing by or through an item box IB is set, by referring to the player object action data Dw, etc., the result of the determination by the control unit  31  in step S 142  is positive. If the player object PO has opened an item box IB, the control unit  31  proceeds to step S 143 . Otherwise, i.e., if the player object PO has not opened an item box IB, the control unit  31  proceeds to step S 145 . 
     In step S 143 , the control unit  31  starts an item lottery event process, and proceeds to the next step. For example, the control unit  31  starts an item lottery event process in which an item lottery event is displayed on the display unit  35 . In the item lottery event, the rotation lottery display of a plurality of types of items I in a possession frame(s) HF that is an empty frame E is performed, and thereafter, any one of the items I is displayed in a stationary state in the possession frame HF. The control unit  31  also starts measuring a first lottery event elapsed time upon the start of the item lottery event process. 
     Next, the control unit  31  sets the first lottery flag on (step S 144 ), and proceeds to step S 145 . For example, the control unit  31  sets the first lottery flag indicated by the first lottery flag data Ds on, and updates the first lottery flag data Ds. 
     In step S 145 , the control unit  31  determines whether or not the first lottery flag is on. For example, the control unit  31  performs the determination of step S 145  by referring the first lottery flag indicated by the first lottery flag data Ds. If the first lottery flag is on, the control unit  31  proceeds to step S 146 . Otherwise, i.e., if the first lottery flag is off, the control unit  31  proceeds to step S 151 . 
     In step S 146 , the control unit  31  determines whether or not a first elapsed time has been reached. For example, the control unit  31  determines whether or not the first lottery event elapsed time that has been measured since step S 143  has reached a predetermined first lottery time. If the first lottery time has been reached, the control unit  31  proceeds to step S 147 . Otherwise, i.e., if the first lottery time has not been reached, the control unit  31  proceeds to step S 151 . 
     In step S 147 , the control unit  31  sets the first lottery flag off, and proceeds to the next step. For example, the control unit  31  set the first lottery flag indicated by the first lottery flag data Ds off, and updates the first lottery flag data Ds. 
     Next, the control unit  31  performs an item lottery result determination (step S 148 ), and proceeds to the next step. For example, the control unit  31  determines whether or not the “fever state” is won, based on a lottery table indicted by the lottery table data De. For example, the control unit  31  extracts a lottery table that is to be used for the item lottery result determination, from the lottery table data De, based on the number of empty frames E, the number of laps in a race, a standing in the race, a course, the type of the race, the type of the player object PO, etc. Thereafter, based on a winning probability described in the extracted lottery table, the control unit  31  determines whether or not the “fever state” is won in the item lottery result determination of step S 148 , and what item I is used to win the “fever state” (i.e., an item I common to all the possession frames HF). If the lottery is lost in the item lottery result determination of step S 148 , the control unit  31  determines an item I that is displayed in a stationary state in each possession frame HF. 
     In the non-limiting example embodiment, the item lottery result determination is performed after the first lottery time has passed. Alternatively, the item lottery result determination may be performed at other timings such as at the start of or during counting of the first lottery event elapsed time, if the timing is before notification of the item lottery result. 
     Next, the control unit  31  determines whether or not the item lottery result determination of step S 148  indicates the win of the lottery (step S 149 ). If the item lottery result determination of step S 148  indicates the win of the lottery, the control unit  31  proceeds to step S 150 . Otherwise, i.e., if the item lottery result determination of step S 148  indicates the loss of the lottery, the control unit  31  proceeds to step S 156 . 
     In step S 150 , the control unit  31  performs an item lottery result notification process for indicating the win of the lottery, transitions to the fever state, and proceeds to step S 151 . For example, the control unit  31  performs an item lottery result notification process in which the item I determined in step S 148  is displayed in a stationary state in all the possession frames HF, and an item lottery result notification event for notifying the user of the win of the “fever state” is displayed on the display unit  35 . Thereafter, the control unit  31  sets the winning flag on, updates the winning flag data Du, starts measuring a fever elapsed time, and sets the object ID of the item I that is displayed in a stationary state in all the possession frames HF in the possession frame data Dr. The control unit  31  sets the action of the player object PO to an action performed in the fever state caused by the item I displayed in a stationary state, and updates the player object action data Dw. 
     Otherwise, i.e., if the item lottery result determination indicates the loss of the lottery, the control unit  31  performs an item lottery result notification process for indicating the loss of the lottery in step S 156 , and thereafter, proceeds to step S 151 . For example, the control unit  31  performs an item lottery result notification process that displays an item lottery result notification event on the display unit  35 . In the item lottery result notification event, the user is notified of the item I that is displayed in a stationary state in a possession frame HF that was an empty frame E and the loss of the lottery. The control unit  31  also sets the object ID of the item I that is displayed in a stationary state in the possession frame HF in the possession frame data Dr. 
     In step S 151 , the control unit  31  determines whether or not the winning flag is on. For example, the control unit  31  performs the determination of step S 151  by referring to the winning flag indicated by the winning flag data Du. If the winning flag is on, the control unit  31  proceeds to step S 152 . Otherwise, i.e., if the winning flag is off, the control unit  31  proceeds to step S 157 . 
     In step S 152 , the control unit  31  determines whether or not there is a touch input has been performed on the touch panel of the information processing apparatus  3 . For example, if a current touch input coordinate point T has been set in the current touch input coordinate data Df, the result of the determination by the control unit  31  in step S 152  is positive. If a touch input has been performed on the touch panel, the control unit  31  proceeds to step S 153 . Otherwise, i.e., if a touch input has not been performed on the touch panel, the control unit  31  proceeds to step S 154 . 
     In step S 153 , the control unit  31  performs an item use process, and proceeds to step S 154 . For example, the control unit  31  performs a process of continually using an item that has caused the “fever state” which is allowed only during the fever period. As a non-limiting example, when the “fever state” is caused by carapace items, the control unit  31  performs the item use process in which a plurality of carapace items IF are disposed around the player object PO, and a projectile carapace item IM is continually fired toward the front of the player object PO at predetermined intervals according to the user&#39;s touch operation, and updates the player object action data Dw and the item position data Dy, etc. 
     In step S 154 , the control unit  31  determines whether or not the fever period has been reached. For example, the control unit  31  determines whether or not the fever elapsed time that has been measured since step S 150  and step S 183  described below has reached the predetermined fever period. If the fever period has been reached, the control unit  31  proceeds to step S 155 . Otherwise, i.e., if the fever period has not been reached, the control unit  31  ends the process of the subroutine. 
     In step S 155 , the control unit  31  performs a process of removing the fever state, and ends the process of the subroutine. For example, the control unit  31  sets an empty frame E in all the possession frames HF in the possession frame data Dr, sets the winning flag off, and updates the winning flag data Du. The control unit  31  sets the action of the player object PO to an action in the normal state, and updates the player object action data Dw. 
     Otherwise, i.e., if the control unit  31  determines, in step S 151 , that the winning flag is off, the control unit  31  determines whether or not the item firing direction has been set (step S 157 ). For example, if the firing direction has been set in the firing direction data Dq, the result of the determination by the control unit  31  in step S 157  is positive. If the firing direction has been set, the control unit  31  proceeds to step S 158 . Otherwise, i.e., if the firing direction has not been set, the control unit  31  ends the process of the subroutine. 
     In step S 158 , the control unit  31  determines whether or not an item I is possessed in a possession frame HF. For example, if an object ID has been set for an item in at least one possession frame HF in the possession frame data Dr, the result of the determination by the control unit  31  in step S 158  is positive. If an item I is possessed in a possession frame HF, the control unit  31  proceeds to step S 159 . Otherwise, i.e., if no item I is possessed in any possession frame HF, the control unit  31  ends the process of the subroutine. 
     In step S 159 , the control unit  31  performs the item use process, and ends the process of the subroutine. For example, the control unit  31  selects an item I that is to be used from items I displayed in possession frames HF in a first-in, first out (FIFO) method. If the selected item I is allowed to be fired in the firing direction set in the firing direction data Dq, the control unit  31  performs the item use process in which the item I is fired as the projectile item IM singly from near the player object PO, and is moved, and updates the player object action data Dw and the item position data Dy, etc. If the selected item I is a type of item that is used by the player object PO itself, the control unit  31  performs the item use process in which the item is used by the player object PO itself, so that the effect of the item I is obtained, and updates the player object action data Dw, etc. After the use of the item I, the control unit  31  also changes the possession frame HF in which the item I was displayed, into an empty frame E, and updates the possession frame data Dr using the changed state of the possession frame HF. 
     Note that in step S 159 , after the use of the item I, the control unit  31  may delete the firing direction indicated by the firing direction data Dq and the second reference coordinate point Rm indicated by the second reference coordinate point data Di, or may maintain them unchanged. In the former case, in order to use the item I again, it is necessary to first touch the touch panel again and perform a drag operation into a direction in which the item I is to be used. In the latter case, at the time that the item I is made available, the item I is immediately used based on the maintained firing direction and second reference coordinate point Rm. 
     In the case where the ready-to-use item IP is allowed to be used when a touch operation (tap operation) is performed on the ready-to-use item IP disposed at the ready-to-use position, the result of the determination in step S 157  is positive not only if the firing direction has been set but also if a touch operation has been performed. In step S 159 , the item use process is performed in which the ready-to-use item IP on which a touch operation has been performed is used by the player object PO itself or the ready-to-use item IP is fired as the projectile item IM in a default direction. 
     Referring back to  FIG. 20 , after the first item lottery process in step S 107 , the control unit  31  performs the second item lottery process (step S 108 ), and proceeds to step S 109 . The second item lottery process performed in step S 108  will now be described with reference to  FIG. 23 . 
     In  FIG. 23 , the control unit  31  determines whether or not all the possession frames HF are an empty frame E (step S 171 ). For example, if the control unit  31  determines that there is data indicating that all the possession frames HF are an empty frame E, by referring to the possession frame data Dr, the result of the determination by the control unit  31  in step S 171  is positive. If all the possession frames HF are an empty frame E, the control unit  31  proceeds to step S 172 . Otherwise, i.e., if the object ID of an item I has been set in at least one possession frame HF or the rotation lottery display is being performed in at least one possession frame HF, then when the item lottery icon AB is being displayed, the control unit  31  removes the item lottery icon AB from the display screen, and proceeds to step S 174 . 
     In step S 172 , the control unit  31  determines whether or not a condition under which the item lottery icon AB appears is satisfied. For example, if the number of times of a lottery has not yet reached the limit of the number of times of selection and execution of the item lottery icon AB that is indicated by the lottery number-of-times data Dv, and the amount of possessed virtual currency indicated by the user possession data Dd is greater than or equal to the amount of virtual currency that is to be consumed by the execution, the control unit  31  determines that the condition is satisfied. If the condition under which the item lottery icon AB appears is satisfied, the control unit  31  proceeds to step S 173 . Otherwise, i.e., if the condition under which the item lottery icon AB appears is not satisfied, the control unit  31  proceeds to step S 174 . 
     In step S 173 , the control unit  31  sets settings for causing the item lottery icon AB to appear on the display unit  35 , and proceeds to step S 174 . For example, the control unit  31  sets the currency amount information M indicating the amount of virtual currency required to select the item lottery icon AB, and sets settings for displaying the item lottery icon AB on the display unit  35 . 
     In step S 174 , the control unit  31  determines whether or not an operation of selecting and executing the item lottery icon AB has been performed. For example, if a touch operation (tap operation) has been performed on the item lottery icon AB displayed on the display unit  35 , the control unit  31  determines that an operation of selecting and executing the item lottery icon AB has been performed. If an operation of selecting and executing the item lottery icon AB has been performed, the control unit  31  proceeds to step S 175 . Otherwise, i.e., if an operation of selecting and executing the item lottery icon AB has not been performed, the control unit  31  proceeds to step S 178 . 
     In step S 175 , the control unit  31  performs a process of consuming virtual currency in response to selection and execution of the item lottery icon AB, and proceeds to the next step. For example, the control unit  31  subtracts the amount of virtual currency consumed by selection and execution of the item lottery icon AB from the amount of virtual currency possessed by the user that is indicated by the user possession data Dd, and updates the user possession data Dd using the virtual currency amount obtained by the subtraction. 
     Next, the control unit  31  starts the item lottery event process (step S 176 ), and proceeds to the next step. For example, the control unit  31  starts the item lottery event process in which an item lottery event is displayed on the display unit  35 . In the item lottery event, the rotation lottery display of a plurality of types of items I is performed in all the possession frames HF that are an empty frame E, and thereafter, any one of the items I is displayed in a stationary state in each possession frame HF. The control unit  31  also starts measuring the second lottery event elapsed time upon the start of the item lottery event process. 
     Next, the control unit  31  sets the second lottery flag on (step S 177 ), and proceeds to step S 178 . For example, the control unit  31  sets the second lottery flag indicated by the second lottery flag data Dt on, and updates the second lottery flag data Dt. 
     In step S 178 , the control unit  31  determines whether or not the second lottery flag is on. For example, the control unit  31  performs the determination of step S 178  by referring to the second lottery flag indicated by the second lottery flag data Dt. If the second lottery flag is on, the control unit  31  proceeds to step S 179 . Otherwise, i.e., if the second lottery flag is off, the control unit  31  ends the process of the subroutine. 
     In step S 179 , the control unit  31  determines whether or not the second elapsed time has been reached. For example, the control unit  31  determines whether or not the second lottery event elapsed time that has been measured since step S 176  has reached a predetermined second lottery time. If the second lottery time has been reached, the control unit  31  proceeds to step S 180 . Otherwise, i.e., if the second lottery time has not been reached, the control unit  31  ends the process of the subroutine. Note that the control unit  31  sets the second elapsed time shorter than the first elapsed time. 
     In step S 180 , the control unit  31  sets the second lottery flag off, and proceeds to the next step. For example, the control unit  31  sets the second lottery flag indicated by the second lottery flag data Dt off, and updates the second lottery flag data Dt. 
     Next, the control unit  31  performs the item lottery result determination (step S 181 ), and proceeds to the next step. For example, the control unit  31  determines whether or not the “fever state” is won, based on a lottery table indicated by the lottery table data De. For example, the control unit  31  extracts a lottery table that is to be used for the item lottery result determination, from the lottery table data De, based on the number of empty frames E, the number of laps in a race, a standing in the race, a course, the type of the race, the type of the player object PO, etc. When an item lottery triggered by selection and execution of the item lottery icon AB is performed, a different lottery table may be extracted, depending on the number of times of an item lottery performed in the same race or the amount of consumed virtual currency, or a lottery table based on which a lottery is won with a higher probability than that of an item lottery caused by opening of an item box IB may be extracted. Thereafter, based on the winning probability described in the extracted lottery table, the control unit  31  determines whether or not the “fever state” is won in the item lottery result determination of step S 181 , and determines an item I that provides a win (i.e., an item I common to all the possession frames HF). 
     In the non-limiting example embodiment, the item lottery result determination is performed after the second lottery time has passed. Alternatively, the item lottery result determination may be performed at other timings such as at the start of or during counting of the second lottery event elapsed time, if the timing is before notification of the item lottery result. 
     Next, the control unit  31  determines whether or not the item lottery result determination of step S 181  indicates the win of the lottery (step S 182 ). If the item lottery result determination of step S 181  indicates the win of the lottery, the control unit  31  proceeds to step S 183 . Otherwise, i.e., if the item lottery result determination of step S 181  indicates the loss of the lottery, the control unit  31  proceeds to step S 184 . 
     In step S 183 , the control unit  31  performs an item lottery result notification process for indicating the win of the lottery, transitions to the fever state, and ends the process of the subroutine. For example, the control unit  31  performs an item lottery result notification process in which the item I determined in step S 181  is displayed in a stationary state in all the possession frames HF, and an item lottery result notification event for notifying the user of the win of the “fever state” is displayed on the display unit  35 . Thereafter, the control unit  31  sets the winning flag on, updates the winning flag data Du, starts measuring a fever elapsed time, and sets the object ID of the item I that is displayed in a stationary state in all the possession frames HF in the possession frame data Dr. The control unit  31  also sets the action of the player object PO to an action performed in the fever state caused by the item I displayed in a stationary state, and updates the player object action data Dw. 
     Otherwise, i.e., if the item lottery result determination indicates the loss of the lottery, the control unit  31  performs an item lottery result notification process for indicating the loss of the lottery in step S 184 , and thereafter, ends the process of the subroutine. For example, the control unit  31  performs an item lottery result notification process that displays an item lottery result notification event on the display unit  35 . In the item lottery result notification event, the user is notified of the item I that is displayed in a stationary state in a possession frame HF that was an empty frame E and the loss of the lottery. The control unit  31  also sets the object ID of the item I that is displayed in a stationary state in the possession frame HF in the possession frame data Dr. 
     Referring back to  FIG. 20 , after the second item lottery process in step S 108 , the control unit  31  performs a process of setting an action of the player object PO (step S 109 ), and proceeds to the next step. For example, the control unit  31  sets the position and orientation of the player object PO, taking into account a steering wheel angle indicated by the steering wheel angle data Dk, an influence from another virtual object, etc., and determines the action, position, orientation, etc., of the player object PO, taking into account the state of the player object PO set in the player object action data Dw, and updates the player object action data Dw. 
     Next, the control unit  31  performs a process of setting an action of the opponent object EO (step S 110 ), and proceeds to the next step. As a non-limiting example, in the case where the action of the opponent object EO is controlled by the control unit  31 , the control unit  31  causes the opponent object EO to perform an action according to a predetermined algorithm, and updates opponent object data Dx based on the action. As another non-limiting example, in the case where the action of the opponent object EO is controlled by another user, the control unit  31  causes the opponent object EO to perform an action based on the other user&#39;s operation in a manner similar to that of the player object PO, and updates the opponent object data Dx based on the action. 
     Next, the control unit  31  performs a process of setting an action of an item (step S 111 ), and proceeds to the next step. For example, the control unit  31  performs a process of moving the projectile item IM that has been set for use and fired from the player object PO by the above process, based on the firing direction data Dq, and updates the item position data Dy based on the position and orientation after the movement of the projectile item IM. 
     Next, the control unit  31  performs a display control process of generating and displaying a display image on the display unit  35  (step S 112 ), and proceeds to the next step. For example, the control unit  31  generates a display image corresponding to the result of a process in each step, based on the player object action data Dw, the opponent object data Dx, and the item position data Dy, etc., and displaying the display image on the display unit  35 . 
     Next, the control unit  31  determines whether or not to end the race (step S 113 ). A condition under which a race is ended is, for example, that a condition for ending the race is satisfied, that an operation for ending a race has been performed by the user, etc. If the control unit  31  continues the race, the control unit  31  returns to and repeats step S 105 . If the control unit  31  ends the race, the control unit  31  proceeds to step S 114 . 
     In step S 114 , the control unit  31  performs a communication process, and proceeds to the next step. For example, the control unit  31  transmits transmission data (e.g., data indicating results of game processes such as the increase or decrease in the amounts of virtual currency and in-game coins, and the result of a race) stored in the transmission data Db to the server  200  through the network  100 . The control unit  31  also receives data from the server  200  through the network  100 , and updates the reception data Dc using the received data. 
     Next, the control unit  31  determines whether or not to perform a purchase process (step S 115 ). For example, if the operation data obtained in step S 103  indicates that the user is going to perform purchase, or if a condition for performing purchase is satisfied, the result of the determination by the control unit  31  in step S 115  is positive. If the control unit  31  determines to perform the purchase process, the control unit  31  proceeds to step S 116 . Otherwise, i.e., if the control unit  31  determines not to perform the purchase process, the control unit  31  proceeds to step S 117 . 
     In step S 116 , the control unit  31  performs the purchase process, and proceeds to step S 117 . The purchase process performed in step S 116  will now be described with reference to  FIG. 24 . 
     In  FIG. 24 , the control unit  31  performs a communication process (step S 190 ), and proceeds to the next step. For example, the control unit  31  transmits transmission data (e.g., data for user authentication (e.g., data indicating a user ID)) stored in the transmission data Db to the server  200 . The control unit  31  also receives data (e.g., data required for the purchase process, that is managed by the server  200 , such as equipment purchasable at the current time, exchange rates, and the amounts of virtual currency and in-game coins possessed by the user) from the server  200  through the network  100 , and updates the reception data Dc using the received data. 
     Next, the control unit  31  obtains operation data from the input unit  34 , updates the operation data Da (step S 191 ), and proceeds to the next step. 
     Next, the control unit  31  performs a purchase process (step S 192 ), and proceeds to the next step. For example, the control unit  31  displays a screen (see  FIG. 18 ) for allowing the user to select equipment, in-game coins, virtual currency, etc., to be purchased, based on the reception data received in step S 190 , and prompts the user to perform selection. If the operation data obtained in step S 191  indicates the user&#39;s operation of determining to perform purchase, the control unit  31  puts the equipment, in-game coins, virtual currency, etc., selected by the user into the user&#39;s possession, performs a process of reducing the consideration thereof from the user&#39;s possession, and updates the user possession data Dd. 
     Next, the control unit  31  determines whether or not to end the purchase process (step S 193 ). For example, if the operation data obtained in step S 191  indicates that the user is going to end the purchase process, or if a condition for ending the purchase process is satisfied, the result of the determination by the control unit  31  in step S 193  is positive. If the control unit  31  ends the purchase process, the control unit  31  proceeds to step S 194 . Otherwise, i.e., if the control unit  31  continues the purchase process, the control unit  31  proceeds to step S 191 . 
     In step S 194 , the control unit  31  performs a communication process, and ends the process of the subroutine. For example, the control unit  31  transmits transmission data (e.g., data indicating what has been purchased in the purchase process of step S 193 ) stored on the transmission data Db to the server  200  through the network  100 . The control unit  31  also receives data from the server  200  through the network  100 , and updates the reception data Dc using the received data. 
     Referring back to  FIG. 20 , in step S 117 , the control unit  31  determines whether or not to end the game process. A condition under which the game process is ended is, for example, that a condition for ending the game process is satisfied, that an operation for ending the game process has been performed by the user, etc. If the control unit  31  continues the game process, the control unit  31  returns to and repeats step S 102 . If the control unit  31  ends the game process, the control unit  31  ends the process of the flowchart. 
     Thus, in the information processing system  1  that performs the above game process, the single input unit  34  (touch panel) can be used to perform the operation of controlling the movement direction of the player object PO, and control the action of a virtual object (an item I) different from the player object PO, and therefore, a variety of processes involved with the user&#39;s operations can be performed. In addition, in the information processing system  1  that performs the above game process, a new in-game effect (the win of the “fever state”) is caused by a combination of game items possessed in the possession frames HF, and therefore, the amusingness of dealing with game items possessed by the user can be enhanced. Furthermore, in the information processing system  1  that performs the above game process, the item lottery triggered by selection and execution of the item lottery icon AB can be performed using an item (e.g., virtual currency, in-game coins, etc.) that can be acquired by consideration or payment used in a game, and therefore, the user&#39;s motivation to acquire the consideration or item can be enhanced. 
     Note that the above game process using the information processing system  1  include the communication process between the information processing apparatus  3  and the server  200 . Alternatively, the information processing apparatus  3  may perform the game process alone without connecting to the server  200 . In particular, a racing game in which the user operates the player object PO can be executed without through the server  200 , and therefore, can be carried out by an internal process of the information processing apparatus  3 . In addition, even in a racing game in which a plurality of information processing apparatuses  3  participate, the game process may be carried out by communication between the information processing apparatuses  3  or between the information processing apparatuses  3  and other apparatuses without through the server  200 . A portion of the process of performing a racing game according to the user&#39;s operation of the player object PO may be executed by the server  200 . As a result, processes in a plurality of information processing apparatuses  3  can be managed by the server  200  in a centralized fashion. 
     In the foregoing, the information process and the communication process are performed in the information processing apparatus  3 . Alternatively, at least a portion of the steps in the processes may be performed in another apparatus. For example, steps in the processes may be executed in cooperation with the server  200  or another apparatus (e.g., another server, another game apparatus, or another mobile terminal) that can communicate with the information processing apparatus  3 . Thus, processes similar to the above processes can be performed by the server  200  or another apparatus performing a portion of the steps of the processes. The above processes may be executed by a single processor or a plurality of cooperating processors included in an information processing system including at least one information processing apparatus. In the above non-limiting example embodiment, the processes shown in the flowcharts are performed by the control unit  31  of the information processing apparatus  3  executing a predetermined program. Alternatively, all or a portion of the above processes may be performed by a dedicated circuit included in the information processing apparatus  3 . 
     Here, according to the above non-limiting variation, this non-limiting example embodiment can be implanted in a so-called cloud computing system form or distributed wide-area and local-area network system forms. For example, in a distributed local-area network system, the above processes can be executed by cooperation between a stationary information processing apparatus (stationary game apparatus) and a mobile information processing apparatus (handheld game apparatus). Note that, in these system forms, each of the above steps may be performed by any suitable one of the apparatuses, and this non-limiting example embodiment may be implemented by assigning the steps to the apparatuses in any suitable manner. 
     The order of steps, setting values, conditions for determination, etc., used in the above information process are merely for illustrative purposes, and other order of steps, setting values, conditions for determination, etc., may be used to implement this non-limiting example embodiment. 
     The above information processing program may be supplied to the information processing apparatus  3  not only through an external storage medium, such as an external memory, but also through a wired or wireless communication line. The program may be previously stored in a non-volatile storage device in the information processing apparatus  3 . Examples of an information storage medium storing the program may include non-volatile memories, and in addition, CD-ROMs, DVDs, optical disk-shaped storage media similar thereto, and flexible disks, hard disks, magneto-optical disks, magnetic tapes, etc. The information storage medium storing the program may be a volatile memory storing the program. Such a storage medium may be said as a storage medium that can be read by a computer, etc. For example, the above various functions can be provided by causing a computer, etc., to read and execute programs from these storage media. 
     While several non-limiting example systems, methods, devices, and apparatuses have been described above in detail, the foregoing description is in all aspects illustrative and not restrictive. It should be understood that numerous other modifications and variations can be devised without departing from the spirit and scope of the appended claims. It is, therefore, intended that the scope of the present technology is limited only by the appended claims and equivalents thereof. It should be understood that those skilled in the art could carry out the literal and equivalent scope of the appended claims based on the description of this non-limiting example embodiment and common technical knowledge. It should be understood throughout the present specification that expression of a singular form includes the concept of their plurality unless otherwise mentioned. Specifically, articles or adjectives for a singular form (e.g., “a,” “an,” “the,” etc., in English) include the concept of their plurality unless otherwise mentioned. It should also be understood that the terms as used herein have definitions typically used in the art unless otherwise mentioned. Thus, unless otherwise defined, all scientific and technical terms have the same meanings as those generally used by those skilled in the art to which this non-limiting example embodiment pertain. If there is any inconsistency or conflict, the present specification (including the definitions) shall prevail. 
     As described above, the non-limiting example embodiment is useful for, for example, information processing programs, information processing apparatuses, information processing systems, and information processing methods, etc., for the purpose of enhancing a motivation for acquiring a consideration and paid items that can be used in a game.
