Cheers F2K, but that wasn't quite what I was looking for.
Basically, I have a squad scattered around Chernarus, and I want the player to go and meet up with all of them one by one. I would like the final guy's location to be randomised (which works) and have a join and lead waypoint placed over him (not visible on the map, but visible as one of those orange arrows on the HUD). How would I go about making the waypoint appear after other waypoints have been completed, making it invisible on the map, and adding a description to it?
Thanks for all your help.
