Patent ID: 8043158

Claim:
A game device comprising: an image display device that displays a game image of a game, the game having a player character being a character operated by a player or being a moving body that the character is on that moves in a virtual three-dimensional space based on operation by the player; an input device for a player's input of an operation signal to operate the player character; and a control section that causes the player character to move to avoid an obstacle object for a fixed period of time, based on the operation signal, wherein the control section performs a behavior prediction calculation for the player character and the obstacle object in the virtual three-dimensional space based on a relative speed and distance between the player character and the obstacle object as well as their respective sizes; and judges, based on a result of the behavior prediction calculation, whether or not contact between the player character and the obstacle object can be avoided by the movement to avoid the obstacle object for the fixed period of time; and wherein when the control section judges that the contact cannot be avoided even with the movement to avoid the obstacle object for the fixed period time, the control section judges whether or not the contact between the player character and the obstacle object can be avoided by accelerating the obstacle obiect to a fixed speed in the virtual three-dimensional space; and wherein when the control section judges that the contact can be avoided by accelerating the obstacle to the fixed speed, the control section accelerates the obstacle to that fixed speed, performs a behavior calculation to cause the obstacle object to move in the virtual three-dimensional space at the accelerated moving speed, and displays an image of the obstacle object moving at the calculated moving speed on the image display device.
