if I get the point then you want the truck to move to a waypoint after a trigger is... well... triggered
you need two triggers andtwo waypoints to do it.
the first waypoint is close or at the trucks starting position.
the second one is where you want him to go after the condition is set true.
okay suppose the first trigger is set to go off when west present.
so have activation"WEST", "PRESENT"
condition: THIS
on activation: movetruck=true
then have a second trigger with condition movetruck.
synchronize this trigger with the trucks FIRST waypoint.
the truck will hold at his first waypoint, waiting for the condition to be set true.
when it is, he will move along to the second.
synching a trigger to a WP only works for the NEXT waypoint.
at least that's what I think, I always use it like this and it works for me, hope it does the job for you aswell
