Delete or move them out of the map? err, sorry im not gonna answer to your question but..
..im wondering why you want to cut off such a nice feature from OFP lol
(dead body's on the ground make much atmosphere lol).
For your script... why you ask if this works? try it yourself!! lol
and if i remember right, OFP has already an automated feature witch deletes "surplus dead body's" in MP.
hum i wasnt very helpfull to ya wasnt i? lolz
