===2D sprites and pseudocode===
In 2D computer animation, moving objects are often referred to as "[[sprite (computer graphics)|sprites]]." A sprite is an image that has a location associated with it. The location of the sprite is changed slightly, between each displayed frame, to make the sprite appear to move.{{sfn|Masson|1999|p=123}} The following [[pseudocode]] makes a sprite move from left to right:

 '''var''' ''int'' x := 0, y := screenHeight / 2;
 '''while''' x < screenWidth
 drawBackground()
 drawSpriteAtXY (x, y) ''// draw on top of the background''
 x := x + 5 ''// move to the right''
