Abstract: A game where in a plan view, the view point and the view direction are set so that both of the player character and the boss character are included within a horizontal visual field and that the virtual camera observes the boss character from behind the player character. In the elevation view, the view point and the view direction of the virtual camera are set so that they are moved into below the player character when the boss character enters over the horizontal line in the area of vertical visual field angle. Therefore, the operation of fighting against the boss character is simplified without different feeling from the fighting against the trivial characters, with securing the dynamics and interest as a game.
