Task generating

[Galm99]

Hi guys,

 

I'm creating a mission where a flight of aircraft fly to a given location and receive a tasking from that point via triggers all of the tasks are replayable, so far I have six possible tasks that can be spawned for that flight.....however I am looking for a way that I can stop the same tasking being generated back to back to ensure the pilot gets different tasks once they fly back to the spawning area.

 

Can anyone help as I'm not sure of the best way to achieve this?

 

Many thanks in advance.
