Abstract: A character-group battle method, recording medium and game device for realistically expressing a group battle through a series of operations are provided. It is determined whether or not there is an enemy horse soldier belonging to an enemy army inside the enemy-search area that has been preset as the range of view of the object horse soldier (S406), and when it is determined that there is an enemy horse soldier (S410, 416, 428), then it is determined whether or not that enemy horse soldier is capable of engaging in battle with the object horse soldier, and when it is determined that battle is possible, then that enemy horse soldier is identified as an enemy that the object horse soldier must do battle (S440), so the object horse soldier approaches the enemy horse soldier until the enemy horse soldier is inside the battle area of the object horse soldier.

Abstract: 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 308 to 312), 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 314, 316).
