Can I store actionFunc ?

[Sooda]

I know that Condition ( function RandomFunction) can be stored to boolexpr but can we store functions also ( TriggerAddAction(randomTrig, function RandomActionFunction) ? It () was first example what poped to my head. It isn' t connected with my older thread where I asked how to destroy trigger (I hope so.).

Yea, it's easy. The function TriggerAddAction() returns the created triggeraction, so we can easily assign it to a triggeraction variable or store it with game cache systems:

function...
     local trigger trig ...
     local triggeraction tact ...

     call TriggerRegisterUnitEvet(trig, ...)
     set tact = TriggerAddAction(trig, ...)

     call SetHandleHandle(trig,"tact",tact)
     //You could also do choose not to set the variable, and do this instead:
     call SetHandleHandle(trig,"tact",TriggerAddAction(trig, ...))

     set trig = null
     set tact = null
endfunction

You can also assign the function that you add to the trigger to a variable. It's called code, and looks like this:

function...
     local trigger trig ...
     local triggeraction tact ...
[B]     local code actions = function SomeFunction[/B]

     call TriggerRegisterUnitEvet(trig,...)
     set tact = TriggerAddAction(trig,[B]actions)[/B]

     set trig = null
     set tact = null
     set actions = null
endfunction

You can't store codes with a game cache system though, because code isn't a handle.

Dosn' t actions need to be destroyed ? Isn' there function like DestroyBoolExpr but instead DestroyactionFunc ? Or actions can be just nulled.

EDIT: I found TriggerRemoveAction and TriggerRemoveCondition, are they some how needed ?

 

[Tom Jones]

Yes, you should remove triggeractions and/or triggerconditions before destroying the trigger.

I think when I create trigger and add actions after that I remove action what would happen ? I don' t want to destroy trigger I just want to know is action functions leaking ? Wierd question... I know.

After you removed the actions, the trigger wont excute them upon triggering.
