I really dont know where to put this post so i decided to put it here, what i want is to be able to jump crawlers, but i dont know if its something to do with scripting modding or what, maybe its not possible but id like to be able to jump crawlers in my maps, like in bo2 for example

A quick google search gave me this link: http://www.thetechgame.com/Archives/t=4009889/call-of-duty-world-at-war-big-dvar-list.html
It's a list of dvars and jumpheight is one, so you could change that value just enough to get over a crawler and be fine.

what do you mean by jump crawlers? do u mean the crawlers from moon and kino or do u mean crawlers that have their legs blown off and jump to get around?

He means jump OVER crawlers

thats easy, just remove or shorten the crawler's clip raw\phys_collmaps\MODELNAME

But in phys collmaps there are just body spawns I mean, legs, arms etc that end in the floor when you kill a zombie

All AIs share the same hardcoded player collision cylinder, so I guess that's not possible.
But you can try setting on the crawler self.pushplayer = false;
