Abstract
A video game including a player operated device for controlling the velocity and direction of movement of a game object. The game player may generate a pulse train having a pulse repetition rate proportional to the desired velocity of the game object. A numerical value of the pulse rate as a function of a clock signal is established, and the numerical value is utilized to change the address of the game object in a video memory so that in successive frames of a video display the game object moves across the display screen.
