## Source Code

    //=============================================================================
    // RandomTrigger
    // Uses a random value to select from a dynamic array of Events when triggered.
    // by SuperApe -- Sept 2005
    //=============================================================================
    class RandomTrigger extends Triggers
            placeable;

    var()        array<name>       EventList;

    event Trigger( Actor Other, Pawn EventInstigator )
    {
            Event = EventList[ FRand() * EventList.length ];
            TriggerEvent( Event, Other, EventInstigator );
    }

    //defaultproperties
    //{
    //     Texture=Texture'Engine.S_Trigger'
    //}

## Notes

If this actor is compiled inside the Unreal Editor, edit the default property Display -> Texture manually as indicated in the comment at the bottom of the code using the `"editdefault class=RandomTrigger"` Unreal Editor console command. If you are Compiling with UCC, simply un-comment the defaultProperties block.
