Another definition for sprite

The term sprite predates XNA itself, and it can be used to refer to any method of displaying a bitmap over an existing background. In Asteroid Belt Assault, we will expand our use of the term sprite to include a class that stores both the bitmap image associated with the sprite, information about its current location on the screen, animation frames, and the code necessary to update and draw the object.

Building the Sprite class

The Sprite class will be used as the basis for all of the objects drawn in Asteroid Belt Assault. It will support collision detection and frame-based animation.
