    Drag drop game

    Right, I'm new. Hello! This might help someone. It's an example of drag and drop, collision detection and physics (a drag puzzle game). I sketched it pretty quickly, and I'm sorry it's not commented. Bit messy but you should be able to grab the helpful bits. I had a nightmare putting this together to be honest, but on the 5th evening this is the result, so I'm pleased. I'll update it soon to make things clearer.
