Making holes in meshes (eg see-through windows or doors in walls)

Yes, I figured all that code might slow it down. I’m back down to 30 FPS as it is, so I’ll need to optimize somewhere.

I was going to add NPCs, but the animation is tricky. It requires sprite sheets, and because I am in a full 3D scene (not a side scroller), I probably need a few animations going in different directions. I can use a shader to flip x-wise, which helps. But it’s a whole new level of stuff, so I haven’t tackled it yet.

I’m going to post my 3D library with some scenes on my blog in a day or so.

Thanks for all your help, and especially for showing me shaders aren’t as scary as I had thought. I am determined to master them, now. :-?
