The shadows were plain images (apparently somewhat transparent white splotches) that had destination out or something, but I couldn't get them to play nice with my own events, since they came from an old template I've built on top. I ditched it for that reason but I want to find a better method to work with the Lamp item.
I've got enemies mostly figured out, for just the basics. Animations, AI states (switch between states, based on a timer, and either choose random states, or choose dependant on criteria, such as walk, idle, alerted, shooting, etc), pathfinding to the player, and both player and enemy-side damage/knockback.
