A course coordinate system processor (252) has a general automobile control unit (257), a movement decision unit (258), and a position decision unit (259). The general automobile control unit controls the running of a plurality of general automobiles on a straight road in a course coordinate system. The movement decision unit determines whether or not another automobile exists in front of an automobile which is under consideration for a movement decision. The position decision unit determines the positional relation between a player's automobile and general automobiles in the course coordinate system, and also determines general automobiles that are positioned in a predetermined visible range of the player's automobile. Positional coordinate data of the player's automobile have been transformed from a world coordinate system into the course coordinate system by a course coordinate system transformation unit (253). |
