A non-transitory computer-readable medium stores an image generation program to perform a method. The method includes determining, in a scene including a timing of a hit of an attack in a battle between characters in a game space, the timing of the hit, and a predetermined portion of a predetermined character and an opponent portion of an opponent character in the battle where the hit will occur, from the predetermined character, the opponent character, and animation data that causes at least the opponent character to perform an action of the battle; calculating a vector from the predetermined portion to the opponent portion at the hit timing; and generating an image of the scene by moving a position of the opponent portion in each frame included in the scene by using the vector such that the opponent portion hits the predetermined portion at the hit timing.

Non-transitory computer-readable medium, device, and method for image generation

The present invention is to provide a method for moving grouped characters whose interaction can be expressed realistically. When an acceleration for moving a character away from anther character when the another character exists within a short distance region of the character, an acceleration for matching the character with speed and direction of another character moving as so to follow a leader when the another character exists within a middle distance region, and an acceleration for moving the character away from another character when the another character exists within a long distance region are calculated (steps to ), and a position of the character on a three-dimensional virtual space is calculated on the basis of summed acceleration obtained by sing the calculated accelerations for each of components x, y, z on the three-dimensional virtual (steps ). Since each character can move while changing its speed and direction according to motion of other characters, motion of each character can be expressed realistically.
