Patent ID: 8226478

Claim:
A game machine for displaying a game screen image showing a picture obtained by viewing, from a predetermined viewpoint, a virtual three dimensional space where an operation target player object which moves according to an operation carried out by a game player and a plurality of teammate player objects belonging to the same team as a team to which the operation target player object belongs are placed, to thereby provide a sport game to be played by the team to which the operation target player object belongs and an opponent team, comprising: a position announcing sound data storage unit that stores position announcing sound data in association with a combination of a first condition concerning a relative position of the teammate player object relative to a position and a reference direction of the operation target player object and a second condition for whether or not the teammate player object is displayed on the game screen; a position announcement target selection unit that selects a position announcement target teammate player object from among the plurality of teammate player objects; a first determination unit that determines whether the relative position of the teammate player object selected by the position announcement target selection unit, relative to the position and reference direction of the operation target player object, satisfies the first condition associated with the position announcing sound data; a second determination unit that determines whether the teammate player object selected by the position announcement target selection unit satisfies the second condition associated with the position announcing sound data; and a position announcing sound output control unit that outputs a sound based on the position announcing sound data in the case where the combination of the first condition and the second condition associated with the position announcing sound data is determined by the first determination unit and the second determination unit as satisfying the first condition and the second condition, respectively, wherein the output of the sound data is restricted based on a coalition parameter indicative of a successful passing of a ball object between the operation target player object and the teammate object.
