vJASS: Dynamic triggers -> How to get triggering Trigger?

10-06-2009, 10:13 PM

Okay guys, simple problem: I create some triggers during run time and within the trigger actions/conditions I would like to get the triggering trigger.
In fact my trigger actions/conditions are itself public static struct methods - which leads to the problem that GetTriggeringTrigger gives the wrong trigger...

Question: How do I get the _real_ triggering trigger, the one that was created by my code?

Zerzax	Would setting the trigger to a global work? Then in that specific action you could know which global to reference.

XieLong	As far as I see a global trigger is no alternative cause at compilation time it isn't known how many triggers will be created and used...

peq	Just make sure you do not use the function/method above its declaration and it should not compile to a TriggerEvaluate call if I remember it right. Why do you need Dynamic Triggers at all?

Could you post a snippet of the code, so I know what you mean? I can't really tell where you are trying to reference the trigger from.

JASS:

struct s_name
    
    static method onSpellEffectFilter takes nothing returns boolean
        local trigger t = GetTriggeringTrigger()    //* This is how you reference it, it works in both the conditions & actions functions
        set t = null
        
        return true
    endmethod
    
    static method onSpellEffect takes nothing returns nothing
        local trigger t = GetTriggeringTrigger()
        set t = null
    endmethod
    
    static method onInit takes nothing returns nothing
        local trigger t = CreateTrigger()
        
        call TriggerRegisterPlayerUnitEvent(t, Player(0), EVENT_PLAYER_UNIT_SPELL_EFFECT, null)
        call TriggerAddCondition(t, Filter(function s_name.onSpellEffectFilter))
        call TriggerAddAction(t, function s_name.onSpellEffect)
    endmethod
    
endstruct

Thanks a lot that was the problem ^_^

TheKid	What difference does it make if its TriggerEvaluate or not? You would still be able to reference GetTriggeringTrigger().

Bobo_The_Kodo	@xombie If vJass adds a triggerEvaluate in the middle (should throw compile error imo), it will return the dummy trigger that triggerEvaluate was called on, that the supposed trigger
