There are three examples in this .gmk: one that shows how to draw a sprite, tiled, across the entire room, one showing how to draw an array, and one showing how to create, then draw the created array.
Code is pretty well commented.
If you see any flaws, please point them out!
If you have any trouble, PM me and I'll try to get to you with that.
Suggestions for another example? Leave a post here.
