[JASS] Event Filter

[Garfield1337]

native TriggerRegisterPlayerUnitEvent takes trigger whichTrigger, player whichPlayer, playerunitevent whichPlayerUnitEvent, boolexpr filter returns event

Is it possible to retrieve casted spell in this event's filter?
I wanted to use it's filter for both conditions and actions but since for getting triggering unit from event i need to use filter unit (GetFilterUnit() returns triggering unit in event) is it possible to get spell? I couldn't find anything like GetFilterAbility()

GetSpellAbilityId()

That returns the spell's ID ('A000').

Tried it already,but it doesn't work with Event filter (returns 0). Works only for condition..
Well i guess i'll just use conditions then

 

[Sevion]

Well, you can set it to a global in the conditions and use it in the actions.

 

[Garfield1337]

I know how there's an easy workaround,but i just thought of using event's filter,not a condition.

 

[Sevion]

Oh, I misunderstood. In the filter, AFAIK, there's no reference to the ability.

I highly recommend to don't use these filter at all, it's obvious that Blizzard didn't finished them, only few response events work in them and they don't act like inside conditions.
But there is a nice trick with the "enter region event" filter, which AutoIndex is using and probably all other newer unit indexers.

Yes, the Enter-Region filter does everything you need it for in most cases. However, for one-time events or for data attachment, a set of Conditions are needed in order to retrieve GetTriggeringTrigger() or GetTriggeringRegion().

Conditions are required for all spells. If your aim is to reduce handle count, you may be interested in Jesus4Lyf's GTrigger or SpellEffectEvent.
