ABSTRACT:
Apparatus for displaying a sprite on a screen comprises sprite attribute tables each including coordinates indicating a display position of a sprite, a pattern code defining the sprite in regard to pattern data, and control data defining a display mode of the sprite. A sprite generator is addressed in accordance with the pattern code to supply the pattern data of a sprite to a pattern data buffer. The sprite is displayed in accordance with the coordinates thereof on the screen. Therefore, the sprite is moved on the screen only by changing the coordinates of a corresponding sprite attribute table.
