[JASS] Can you do any of this? (in standard JASS)

- Remove a triggeraction ?
- Call a local triggeraction ?

I want to call certain functions dynamically (without manually calling functions). And use of triggeractions are my best bet on how to achieve this.
Yeah, you're shaking your head at me, but I'll continue anyway.

I have an unfinished function that does nothing at the moment and goes like this:

function ReadString takes triggeraction ReadAction returns nothing
endfunction

I wanted it to "call ReadAction", which I tried, even though I felt certain that it wouldn't work
(And I felt stupid while trying, and I still do)

So, do you think I am a helpable person? If so, please enlighten me.

I was a bit confused about your request, did you mean something like this?

function RunFunc takes code c returns nothing
    local trigger t = CreateTrigger()
    call TriggerAddAction(t, c)
    call TriggerExecute(t)
endfunction

In vJass it could be optimized to use a global trigger.

Okay, well I think locals are all I need for this fortunately. It's just important to me that I don't have a ton of triggers, so as long as the trigger is temporary, it's good.
I don't know if local means that it's temporary because I'm very new in the world of JASS.

What kind of handle is "code"? Can you explain it for a GUI-user?


I am using a loop that checks substrings from a string used to store a multitude of data as an alternative to using an array. The loop is supposed to do some action based on external factors and the signs it finds in the string during the loop. So, let's say we have 3 different actions. Examples: 1: (create MyItem(IntegerB) for (hero); 2: (create unit of (MyUnitType[IntegerB]) at TempLoc; 3: Set Current life of (hero) to R2I(IntegerB)

The variable actions are defined before the loop starts. Now this is all theoretical, but I want to find a way to actually do this. But I think that maybe it could be done by creating and removing triggers (or using local triggers). So, I will experiment with that if no better sollution comes up. Thanks.

So that is what you wanted? To run a function dynamically?
Anyways, create a trigger variable via the variable editor and change the code to this;

function RunFunc takes code c returns nothing
    call TriggerClearActions(udg_YOUR_TRIGGER_VAR)
    call TriggerAddAction(udg_YOUR_TRIGGER_VAR, c)
    call TriggerExecute(udg_YOUR_TRIGGER_VAR)
endfunction

And a code variable is not a handle, it's a function. So you would use this like

call RunFunc(function FuncName)

I see! I get it, thanks.
