Then problem with this is that you may select any place over the map to be evacuated to, so I dont see any clear criteria to define the final egress direction and I just placed it 3Km N of the last evacuation pos:
mando_airsupportdlg.sqf
_targetpos = [_targetPos select 0, (_targetPos select 1)+3000, 100];
_wp = _group addWaypoint [_targetpos, 0];
[_group, 6] setWaypointStatements ["true", "deleteVehicle (vehicle this);deleteVehicle this"];
[_group, 6] setWaypointTimeout [0, 0, 0];
[_group, 6] showWaypoint "NEVER";
[_group, 6] setWaypointSpeed "FULL";
[_group, 6] setWaypointType "MOVE";
If you have any suggestion about this ...
