Day 5

I fixed the wall snag, and increased the position resolution by a factor of 16 to slow things down. I'm happy with the physics now.

Next, I added more mobs to play with. I gave them AI that wanders around randomly, and after watching the physics show, I had them follow the player until they get bored. To spice things up, I added some test walls, and implemented line-of-sight. (My Bresenham's implementation really came in handy!) Now mobs forget about you if they can't see you. I can't remember the last time I had AI this complex.
