[JASS] TriggerUnRegisterEvent

emperor_d3st · Jun 8, 2008

Hi, I was making dynamic triggers today and when I was adding all kind of TriggerRegisterEvents with unit variables as parameter I was wondering what happens to them once the registered unit is removed from the game.
Do these lines stay there in the memory until the end of game or do they get released when the unit is removed?
If they stay there, should I remove them using event type variables?

Yeah, afaik those lines stay there, there is no reason why they should be erased. How were you planning to remove those events? Why would you want to remove those events anyways? I didn't quite get that part.

Well, first because they eat up the memory (leak) or do they not?
Second, I don't want units to always fire the trigger.

Then destroy the trigger when the unit it pertains to is destroyed?

Yes, but let's say I have, I don't know, 70 units registered to a trigger with some event. This means I have to destroy the trigger and readd the units OR create 1 trigger / unit from the begining. The third solution is to have 1 trigger but add an additional condition, like, when I don't want the unit to fire the trigger I add the unit a dummy ability or change its custom unit value or something like that.

Thanks for the help again.

Yes, but let's say I have, I don't know, 70 units registered to a trigger with some event.

Then let's say you, I don't know, recode your approach to the system >>

This is the whole reason GUI systems of this sort are discouraged in the first place.

OR create 1 trigger / unit from the begining.

Exactly.

No and thats why someone needs a handle attachment system for making Any Unit Takes Damage
otherwise that someone just would unregister that unit from the global trigger

Crap, I read you're post like 5 times and I still don't get it. But I have a theory on what you said and this would be the answer: you can't unregister a unit from a trigger and you can't remove the event unless you destroy the actual trigger.

Okay, it's clear now. Thanks.

To avoid any misunderstanding, I was referring to Need_O2's post.
