How to make a trigger occur once

[Darkduke219 oRzac]

So I made a trigger where the event starts when a unit enters a region, then all the stuff happens which is fine.

However, this trigger repeats itself for every unit that enters the region thus multiplying all the effects, I have added Turn off this trigger at the end but it is still occurring.

So I kept trying and got it to work, but simply making the condition if a destructible is alive, because in my cinematic the destructible dies and spawns units, was wondering if their was a simpler way to do this.

Seems like it could be two issues:
1) there are wait steps, thus the trigger is still on while it runs (move the turn off step to the first line)
2) something in the code is breaking and the turn off function is not being called (Lua or JASS map? Lua would not print errors by default)

Try putting "Turn off this trigger" as the very first action, that won't prevent a first execution but should disable any further
