My workaround for this:
If u are leader, make 2 separate groups. One is u. The other is 'secondgroup' or somethin.
Make the 'on activation' of secondgroup's 'get out' waypoint say
(units secondgroup) join (group player)
den, u get ejected automatically on landing, and dey all jump out then join u.
another way wif just one group is to put "readytojump = true" in the chopper's land waypoint, then put a trigger which says
condition:
readytojump && ((getpos heliname select 2) < 5)
onactivation:
(units playergroup) action ["EJECT", heliname]
then they *all* exit at the same time as soon as da heli is low enuf so no-one gets hurt. Use land "get out" instead of land "land" - makes a good 'hot drop' landing.
Cheers,
