I fixed the sound and ace interaction for dedicated servers...
first the sound, just put a trigger under the metal barrel and rename the metal barrel to bomb1
ACTIVATION: ANYPLAYER
ACTIVATION TYPE: PRESENT
REPEATABLE: UNCHECK
SERVERONLY: UNCHECK
IN CONDITION: call{player in thisList}
ON ACTIVATION:
if (!isDedicated) then {[] spawn { while { alive bomb1 && bomb1 getVariable ["a3f_bomb_active", true] } do
{
playSound "beep_strobe"; sleep 2;
}};};
now the ace interaction:
on line 4 of the bomb.sqf file change to if(isDedicated) exitWith {};
