My fault, I'll go into greater detail. I have an object placed within eden, named aavc7a1 under variable name (the literal name of the car) for simplicity. Then I have a trigger with the condition of the script i.e "{_x in aavc7a1} count (playableUnits) == {alive _x} count (playableUnits);" the trigger is set to operate on the server only, and has the activation, mapa = true; which connects to an objective.
edit:
I want the server to check for any players within the vehicle. Meaning the second a single player enters the vehicle the condition of the trigger is met
