That doesn't work either.
I am using the Hellenic Huey's. Since they don't come with co-pilots for the co-pilot seat I have a pilot grouped to the Huey with
npc1 moveInCargo heli1
in the co-pilots init field. In addition there are a small group of soldiers with the lead called group1, and in his init field
{_x moveInCargo Heli1} forEach Units group1
.
Once the Huey has the player on board it will move to a WP beside Corazol, it has
s1 in heli1
in its Condition field (and a time of 5 seconds before it 'activates', the next waypoint is a transport unload one at an invisible H at Obregan. Then the Huey has a getout WP at Corazol Airport.
EDIT
Assuming the first waypoint is attached to the helicopter: the helicopter takes off and hovers above the waypoint, right?
One solution is to add "this flyInHeight 0" to the chopper's init field and "heli1 flyInHeight 150" to the first waypoint's activation field.
What do you mean by attached? The WP is the Hueys.
The second part just makes the Huey start its engine and not move.
