   Loop tree?
  Am working on a game with a looping background made from different blocks. The blocks can't be randomly chose since some fit together and some don't, but I do want it to be random as much as possible. So I made a tree with node that loop back to parent nodes at some point. So I can call a random child from the current node and it will always fit with the current. I was wondering if there was a name for this pattern or people just call this a tree (after all, it is...)   
  "Cyclic graph" perhaps.   ;Quote:Original post by leiavoia"Cyclic graph" perhaps.That's what it sounds like to me.   ;  I'll read on it, thanks!
