As you can see I've decided to keep the autofringing. I just like it too much. And yes, the bottom of the house has green on it.
Of course, I think it was all for naught[sad]. I REALLY want the game to be a mouse-controlled RPG similar to Baldur's Gate. If I do it like that, then I'll have to make the buildings into entities instead of tiles. Another problem with that is I have to learn A*, which I should do anyway. So, I'm back to pondering, but I have to hurry up and figure this crap out.
Edit: Actually, I don't HAVE to make the buildings into entities, but I could get fancier that way.
Anyway, bedtime for me.
