Hi!
I already have a game with a few levels and I wonder how difficult it will be to implement this lighting system into my game? Is it based on adding a controller object and light sources and some special layer?
Hello!
It's very easy; Yes, you create a manager/controller for the lighting system and add the lights to the room, using layers/depth or via code. You can check out this quick start tutorial:
