Hello,
If you want to use the planes as your reinforcement then you could also do the following:
place the pilot on the tarmac
place the plane as Empty/Air/PlaneName
Give the pilot a Move trigger, close to the plane, followed by a Getin Wp
(on the plane) and then the waypoints where he should go to do his attack etc.
Now place a trigger, Activated by (P.e. Radio alpha), Type switch, And synchronize it with the first (move) waypoint.
(To synchronize (F5) draw the line from the trigger to the waypoint)
Now I have only done this with one plane but you can also synch the same trigger with the WP's on other pilots/planes you want to be in the first guys group and then give the other guys a JOIN waypoint to the first guy after their getin waypoints.
(correct me if I am wrong, anyone)
I have made you an example mission for one plane, However it is on the bigger airfield in the west, and I think the Northern airfield is not suited for AI planes as there is only one airfield that is coded to be used by AI on each Island. I tried that one before but the planes just turned left or right at the start and they drove straight off into the sea.
Anyway I hope this helps,
