Here's an excerpt from Matt Greer's site ( http://www.mattgreer.org/post/4dynamicLightingShadows )
[quote:y2h0a32f] I have to admit I am cheating a little bit, as I am setting my lightColor to a dark grey, and not sending out light but actually darkness. This is because lighting the pixels up makes them looked washed out. There are ways to resolve this, but for now I’m cheating a smidge.
Does anyone here know how to fiddle with the code to actually send out lights as well as darks?
Edit: Or perhaps only lights instead of darks?
