  • Patent number: 6045446
    Abstract: An object-throwing video game system displays at least an image of a throwing body and an image of an object to be visually hurled from the throwing body in a game space. The object may be a hammer, a shot, or a discus, and the throwing body may be a contestant who hurls the hammer, the shot, or the discus. The image of the throwing body is controlled to visually move in preparation for visually hurling the image of the object in the game space in response to manual operation of a controller, and the image of the object is controlled to be visually hurled from the image of the throwing body in the game space in response to manual operation of the controller. An image of an object-throwing guide is also displayed in the game space to indicate a throwing direction in which to hurl the image of the object from the image of the throwing body and which progressively varies depending on the movement of the image of the throwing body for visually hurling the image of the object.
