IMAGE GENERATION SYSTEM AND PROGRAM

An image generation system and program for implementing motion representation with variety while using a motion play technique based on motion data. The present invention performs a first motion correction in which a head or gun of an enemy character is turned toward a player (or player's character or virtual camera) and a second motion correction in which the skeleton shape of the enemy character is slightly changed when the enemy character is hit by a shot. In the second motion correction, the skeleton shape is slightly changed by using a restoring force for returning the skeleton shape to its original form and hit information (hitting force and direction) while gradually reducing the amount of slight change of the skeleton shape as time passes. The position and rotation angle of the base (or body coordinate system) of the enemy character are fixed to those specified by the motion data. Flags to be used for individually enabling or disabling motion corrections are respectively set to the enemy characters.
