maybe possible by playing the lying animation of the character...
Try this:
;Artificial Intelligence Script
desc = appear as dead
;Triggers
:state=0:animate=[62 or 65],state=1
:state=1:setframe=[39 or 79],suspend
;End of Script
I'm trying it out myself, maybe these are the wrong animations.
Hope it works
EDIT: The script doesn't work and I can't really find the problem...
