Hey brother comrades it worked. Thanks Bored_onion, planck, THobosn, triggerhappy and The Architect, ok, time for me to get useful for a change . put this statement in the "On Activation" field of any of its waypointS:
Heliname setFuel 1
assuing the name of the helicopter is Heliname, so it will refuel eveytime it reaches that waypoint.
I wish i could spend time learning scripting hardcore. its just that there are so many other things for me to learn right now(work related , Java, Visual Basic etc.) That why sometimes I wish I had bedges's or macguba's brain.
