Many folks are using Kalle’s box2dlights library. As the name implies, it’s a box2d based 2D lighting system, that’s very simple to integrate into your game. We now build nightlies for it on the build server. I highly suggest using those from now on. You can find them at http://libgdx.badlogicgames.com/box2dlights/ Works with all backends, including the GWT backend thanks to siondream providing a few minor fixes.
