A controller is provided with a joy stick for designating a direction for a traveling body to run in, and transmits a radio signal such as an infrared ray in a target direction (alpha), in which the joy stick is brought down. The traveling body receives the radio signal to acquire the target direction (alpha) and to detect the direction for the radio signal to come in, and determines a relative direction (beta) of the traveling body with reference to the coming direction of the radio signal. Direction changing means is driven to align the directions (alpha and beta) with each other so that the traveling body may travel automatically in the target direction. As the player merely brings down the joy stick in the direction for the traveling body to run, therefore, the traveling body runs in the direction so that the control is drastically simplified. |
