Custom Graphics Engine
FAQ

Skin2code.txt shows, to me, the routine for drawing the entire screen. I don't understand how skin2code works if there is only one cell in the viewport that is of skin2, and the rest are of skin0. 
Answer

When you specify a ceiling, floor, middle, and WALL graphic ID, this grants the user one graphic ID associated with a single picture which you call a wall. But in the game itself, there are many wall graphics from many angles. Was this intended on being a sole-picture variable or perhaps the start of some 'array' where you add offsets to fetch pictures? I suppose since all it is is a number, it is what you make of it from using the WallGrapicID call.
