need help when is possible

How can I create a plane in the air, something like a security area? For example, if an enemy plane comes within a radius of 500 meters, start the media player: "Watch enemy plane at 6 o'clock" ....
somehow I can not connect to my plane with the translator complex.
It should be a trigger that always moves with the plane.
Thanks in advance for suggestions.

If I understand you correctly, you need to use the proximity trigger and not the Complex Trigger to do this. Object link the proximity trigger to the plane that you want to measure proximity to, and then set the advanced properties of the proximity trigger to the coalition of the enemy plane, then target link the proximity trigger to the thing you want to activate (subtitle, media player, etc). I have noticed that the proximity trigger doesnt seem to work when object linked to spawned objects, so the vehicle/plane must be present at the start of the mission in order for this to work.
