How do you differ if a box hits another from above or right if one box hits the other at it's corner? Like this: |=====| |=====| |=====| |=====| |=====| |=====|

Thank you, but I don't know, when I will continue working on it, or if I will do it at all. The idea of an editor is very nice, but sharing levels on this website could become very hard to program because you have such less space.

@ JetlLennit: Thanks @ shrucis1: You don't need them to be dragable. Just make three buttons. First click for selecting, second click for placing.
