I am trying to make a trigger to do the following:

player 1 or player 2 moves a unit into a specific region ( Ive already placed the region)

Once the unit has moved into the region, hostile players spawn (ambush)

I have set the Event as "Any unit enter region" but it seems to count all doodads in the region as units. and when the game spawns I have like 300 ambushers already spawned.

I need a way to specify "Player 1" and "Player 2" moving into the region.

Thanks in advance for any help you guys might have.

Not sure if its the most efficient way to do it but this sounds like what your looking for

Example Trigger
    Events
        Unit - Any Unit Enters Example Region
    Local Variables
    Conditions
        Or
            Conditions
                (Owner of (Triggering unit)) == 1
                (Owner of (Triggering unit)) == 2
    Actions
        ------- Whatever acctions you need to spawn your ambush go here

If you want the ambush to only fire once make it so that the trigger is turned off at the end of the actions

Hope that helps
