DancingOctopus,

Good suggestions. With regard to calculations, I have already considered options and have decided to use a simple system of "light" sprites that listen for a player's proximity. When the player is in range, the light map nearest the angle between the light and the player is applied using the appropriate percent. The lightmaps use eight-directional lighting, so all angles greater than zero and less than ninety snap to forty-five.

I was very impressed by the UnitZero example, but it's alot more than I had in mind. It's beautiful, beautiful overkill.

I hope to have something to show by next week. Better start scribbling.
