Okay, so I found out that these lines spawn the bleeding particle effect... I think.
(fn_damagehandler.sqf)
if(!_isHit) then {
//Create Wound
_unit setVariable["hit_"+_wound,true,true];
PVDZ_hlt_Bleed = [_unit,_wound,_damage];
publicVariable "PVDZ_hlt_Bleed"; // draw blood stream on character, on all gameclients
[_unit,_wound,_hit] spawn fnc_usec_damageBleed; // draw blood stream on character, locally
Now I only need to figure out how I can reuse this code into the dzai damage handler.
