Ok, just to show how awesome and simple libgdx box2d and box2d lights are check this out. I just started learning box2d yesterday and have come up with this. I’m really enjoying learning this library and I hope others will realize how great it is!
Use WASD to move and scroll to enlarge or decrease light.
