.Map :: MoHAA Mapping

Does anybody know how to make players fly back into walls or whatever when they get shot. I seen it on another server but have no idea where to find it.

Hi all, i just got my first mohaa server a couple months ago and want to add some boxes and such but i dont understand how to get my coord comand to work. I bring up console and type coord but nothing is happening what am i missing? any ideas?
