ADDSPRITE

Description

This command adds a Sprite to a GRAPHICBOX or a Graphics Window, assigning to it a name, and one bitmap name or a list of several bitmaps names.

The bitmap must be loaded first with the LOADBMP command, or created at runtime.

A sprite bitmap must include a mask above and a sprite below, like this:

To delete a Sprite, read REMOVESPRITE.

The Background and Sprites will not show up until a DRAWSPRITES command is issued.
