Simple enough question, is there any reasonable built-in CRPL function that tells you whether a terrain cell is occupied by a unit? I want to know for the purposes of placing objects that can't overlap existing towers/collectors etc...
If there's not a function built in, is there any simpler method for doing this than parsing all units, checking their type, populating a 2d array and manually checking your point against all the others? I'm down to do that if necessary, but I thought I'd ask first since it's going to be time consuming and probably not too efficient on the ol' CPU.
