TriggerRegisterVariableEvent

How does that function work exactly? Judging by the parameters, I would say it doesn't take local parameters. But it can take struct members, right? What would the string for that be then?

JASS:

struct Data
    
    public real blah
    
    // struct is created somewhere
    
    method lulz takes nothing returns nothing
        local trigger t = CreateTrigger()
        
        call TriggerRegisterVariableEvent(t, "?", EQUAL, 0)
        
        // some other stuff here
        
        set t = null
    endmethod
endstruct

I have a feeling that this isn't possible :P

Troll-Brain	It works only with not array real variables, so it would work for a static member. Anyway this even is kinda useless since it only works for reals and not integers.

Silvenon	Yeah, but I am using reals. Plus, I don't know any other way to check when a variable reaches a certain value without checking periodically.

Just use an if/then just after you set it ?
It would me more efficient anyway.

Silvenon	I don't get it. So you're suggesting the periodical check then? When should I use if/then/else? EDIT: OK, I got it, this is solved. Thanks for the help :D

DioD	every time given real variable changed engine checks its new value. if its new value hit some limitop event will fire. limitop event for equal kinda buggy and will never fire actually. notequal limitop have same odd behavior. this events will cause many problems, soo it much more better to check values on your own when you set them.

Silvenon	Oh, thanks. I didn't know EQUAL is buggy... It's a good thing I don't use limitops much, and when I do, I mostly use "greater/lesser than or equal to".

grim001	Any time you use limitops it could easily be replaced with manual checks... I wouldn't trust TriggerRegisterVariableEvent, it has way too many problems.

Just use trigger execution for "dynamic" variable events.

An example

JASS:

function Func takes nothing returns nothing
    //...
    loop
        exitwhen i > 11
        if Something_value[i] > interchangable then  
            call TriggerExecute(Something_theTrigger)
            return
        endif
        set i = i + 1
    endloop
    //...
endfunction

scope Something initializer Init
    globals
        public trigger theTrigger
        public real value
    endglobals
    
    private function Actions takes nothing returns nothing
        //Do things
    endfunction
    
    private function Init takes nothing returns nothing
        set theTrigger = CreateTrigger()
        call TriggerAddAction( theTrigger, function Actions )
    endfunction
endscope
