You gyz were pretty close
Okay, you can do this two ways. First is to group the chopper to the player and then the actions in the action menu will appear.
The second is a bit harder. First make a chopper and name it soar_loons1. Then make the player have a waypoint where you want the pick up to be. In the
On Activation:
line of the waypoint copy the line out of the BAS readme. You should now have something like this:
On Activation: CHOPPER exec "\bas_soar\fx\aipickup.sqs"
The last part in quotes doesn't matter. If its different I typed it wrong. What you do need to change is the CHOPPER part. Type in
soar_loons1
. Then play the mission and when you reach tat waypoint the chopper will come for you.
