[Spell] What is the point of "Turn off" and "Turn on" within the same trigger?

[Ugabunda]

Hi guys,

I see sometimes triggers that use "Turn off" and "Turn on" within the same trigger in sequence. What is the reason behind this?

• Example spell
  • Events
    • Unit - A unit Is issued an order targeting an object
    • Unit - A unit Is issued an order targeting a point
    • Unit - A unit Is issued an order with no target
  • Conditions
    • ((Triggering unit) has buff Berserker's Call Target) Equal to True
  • Actions
    • Trigger - Turn off (This trigger)
    • Unit - Order (Triggering unit) to Attack BerserkerCall_Caster[BerserkerCall_Index]
    • Trigger - Turn on (This trigger)

Thanks!

This needs to be done to prevent infinite loops.
Giving order through trigger will make this same trigger react to given order, unless it's turned off for this instant moment.

Same could be said about damage event triggers, where you deal extra damage (the same trigger will react to this again, so it needs to be turned off for a moment).

Thanks for the explanation - makes sense!

Other case is if you use "Wait" in the trigger and you don't wanna make the trigger runs 2 times at the same time.
