[JASS] TriggerRemoveAction question

[deathismyfriend]

i want to know how to remove an action from the trigger
trg_BKC is the trigger

    call TriggerRemoveAction( trg_BKC, triggeraction whichAction )

this is the action i want to remove if someone could tell me how to do this thx

    call TriggerAddAction( trg_BKC, function Actions )

 

[Doomlord]

call TriggerRemoveAction (trg_BKC, TriggerAddAction( trg_BKC, function Actions))

TriggerAddAction returns a triggeraction handle.

That is just an example on how to remove the triggeraction.

In reality, you will often destroy the triggeraction only after the function has finished.

Like this:

function blah1 takes nothing returns nothing
    // blah blah blah
    // Function completed. Remove triggeraction

    call TriggerRemoveAction(tga_BKC, <your triggeraction handle>)
endfunction

function blah takes nothing returns nothing
    // blah blah blah
    call TriggerAddAction (trg_BKC, function Actions)
endfunction

Here you have example code:

function aaa takes nothing returns nothing
    call BJDebugMsg("function aaa is running!")
endfunction

function InitTrig_bla takes nothing returns nothing
    local trigger t = CreateTrigger()
    local triggeraction ta = TriggerAddAction(t, function aaa)

    //make the trigger run
    call TriggerExecute(t)

    //remove the action
    call TriggerRemoveAction(ta)

    //run the trigger again
    call TriggerExecute(t)

    //destroy the trigger(prevent leaks)
    call DestroyTrigger(t)
    set t = null
    set ta = null
endfunction

this should make print function aaa running only once, if it does it twice, it is most likely blizzards fault for not making TriggerRemoveAction working

Ya I couldn't get triggerrmoveaction to actually remove the action I have it originally call the function once and remove it but it didn't want to work so I just made it another way thank you tho ill give rep later
