[General] Remove Special Effect from Unit Group

[Warseeker]

Hey, how can I remove a special effects from a group of units? I tried to do this but it doesn't work :

• Trigger
  • Events
  • Conditions
  • Actions
    • Unit Group - Pick every unit in (Units in (Playable map area) owned by Player 1 (Red)) and do (Actions)
      • Loop - Actions
        • Special Effect - Create a special effect attached to the overhead of (Picked unit) using Abilities\Spells\Other\TalkToMe\TalkToMe.mdl
        • Set SpecialEffect = (Last created special effect)
        • Wait 3.00 seconds
        • Special Effect - Destroy SpecialEffect

Can someone explain me what's wrong with this trigger?

Waits make both unit and player groups crash, that is, anything below "wait" action won't be executed for each enumerated unit/player. You'll need some kind of "MUI" trigger that handles those special effects for destroying them later.

That action is a loop and you are overwriting the "SpecialEffect" up until the last unit checked in playable map area owned by red group, need to index it so you can read the right value back after 3 seconds. Could try with hashtables or custom unit value or an array.

Would be quite easy in JASS, much more bothersome in GUI
Far from impossible though, use a timer instead.
Then use either a hashtable to attach the effect to the timer.

Functions called by the for group action cannot call TriggerSleepAction. Trying to do so causes a thread crash. Same goes with trying to call TriggerSleepAction inside conditions, or timer callbacks.

I see. Thanks guys for the suggestions.

It's more complicated then just wait trigger.
