i need help making this trigger fire 1 time when a unit enters the location. not everytime a unit enters the location...

    Events
        Unit - Any Unit Enters ProtossWaterWall
    Local Variables
    Conditions
    Actions
        General - While (Conditions) are true, do (Actions)
            Conditions
                (Owner of (Triggering unit)) == 1
            Actions
                Unit - Create 4 Void Ray for player 11 at (Center of Player1) using default facing (No Options)
                General - Wait 30.0 Game Time seconds

Right now if i send 3units to ProtossWaterWall (location) it will spawn (4x3) 12void rays, i only want it to spawn 4 total. any ideas?

@tdhsst: Go add an action that turns the trigger off.

@SoulFilcher:

but if i turn the trigger off then in 30seconds (wait time) it will not fire again...

OR can i add an action to turn trigger off then wait 30seconds action then an action turn trigger on???? lol

@tdhsst: Go Yeah, you can try something like that.

@SoulFilcher:

            Actions
                Unit - Create 4 Void Ray for player 11 at (Center of Player1) using default facing (No Options)
                Trigger - Turn (Current trigger) Off
                General - Wait 30.0 Game Time seconds
                Trigger - Turn (Current trigger) On

it does spawn 1 time but when i enter the area again with in 30seconds i get an error code.. not to mention HUGE lag... dont know why though~

@tdhsst: Go

I wonder if it's because you create units in the area that is defined in the Events of your Trigger? This would explain the lag. Try to switch your 'Create'-Trigger with your 'Trigger - Turn (Current trigger) Off'-Trigger.
