Hmm, I think I have tried this yesterday, I'm not sure, but the Self block isn't dockable into the other block, maybe I need to get it into an attribute before. I'll test this tonight, I'm at work.
Thanks dude !
If It's not good, I think I'll cheat and get the width of the block, the only problem is to make blocks with differents sizes (for now it's not important, but after this I'll make blocks with same size but with differents properties, like snow, ice, etc.)
It's a little complicate :
Scene generates blocs
Blocs generates trees
Blocs generates monsters
trees generate grass
etc.
I want this game is totaly random.
