Patent ID: 7674167

Claim:
A computer readable storage medium storing a traveling time calculation program which causes a computer to execute a process for calculating a traveling time, by using a unit time based on which a game screen is updated, required by a movable object to travel from a first position to a second position in a game space, wherein the traveling time calculation program causes the computer to function as: position determination programmed logic circuitry which determines a position of the movable object using a velocity vector with every update of the game screen; virtual position setting programmed logic circuitry which sets a virtual position between positions immediately before and after the movable object passes through the second position, and shifts the virtual position using an infinitesimal unit vector obtained by dividing a velocity vector, at the position immediately before the movable object passes through the second position, into predetermined numbers; and traveling time calculation programmed logic circuitry which calculates a traveling time from the first position to a position immediately before or after the virtual position crosses the second position.
