dchan200,
That was it. I think what happened is I watched a tutorial for triggers on youtube, but the trigger was for something else. I assumed it carried over to what I was doing, obviously not. Thank you for the reply.
To start off I am new to mission editing. My problem is trying to make markers only appear once the trigger has been activated. I have set up the trigger as simply as possible by making it an area that BLUFOR has to enter. The marker name is "aircraft" with the alpha slider at 0% . Next is the trigger Type is "Guarded by OPFOR" Activation BLUFOR and Activation Type Present. The conditions box just says "this" and the On Activation box has "aircraft" setMarkerAlpha 1. I have gone through just adding a semicolon on the end and nothing. I tried using the empty map marker and using setMarkerType to change into a visible marker. Nothing works when I play as the BLUFOR soldier and walk into the trigger area. Also I did not change the default values for timer settings on the trigger. I imagine there is something very basic I am not understanding or missing. Any help would be appreciated.
