Anyone care to explain timer usage...?

[Lyerae]

Well, everyone keeps saying to use a timer system (in a bunch of different threads scattered everywhere), so I went and found one that I liked (TimerUtils Blue, in this case. Looked like the easiest to learn (KT2 is confusing...) ), but I have no idea how to use it.
Now, the documentation says to do: [ljass]local timer t = NewTimer()[/ljass], which creates a timer, but after that. I'm stuck (other than ReleaseTimer(), which I know how to use (it destroys a timer)).

So, how to I use this brand-new, shiny timer?
How to I implement it into a trigger, how do I set it, how do I make it useful, etc...

Thanks for any help.

KT2?! Confusing?! It has exactly two functions. One of them takes three arguments, the other takes none. What's so confusing?

 

[Lyerae]

I have no idea, really. It just confuses me...
Oh, and HOLY CRAP THAT WAS PROBABLY THE QUICKEST REPLY EVER.
Seriously. That was fast.

 

[Azlier]

function Callback takes nothing returns boolean
    local integer Data = KT_GetData() //Get attached data. If you don't want it, just call KT_GetData().
    //Do stuff.
    if something then
        //Returning true makes the system stop calling the callback.
        return true
    endif
    //Returning false tells the system to call the function when the timer expires again.
    return false
endfunction

function Omg takes nothing returns nothing
    call KT_Add(function Callback, data, period)
endfunction

 

[Lyerae]

Yep. Still confusing.

Remember, I'm no JASS master...

 

[Azlier]

It's less complicated than TU blue. It's not a tough concept. Read over it a few times.

You can ignore data attaching right now. Just make sure to call KT_GetData exactly once in the callback, whatever you do.

 

[Lyerae]

What is the callback?

 

[Azlier]

The callback is the function that is fired after the timer expires.

 

[Lyerae]

Uh-huh... And what's that mean?

 

[Azlier]

It means that...
[lJASS]KT_Add(function Callback, 0, 10/*This is the period.*/)[/lJASS]

It means that Callback (a function) will be fired every ten seconds until the function returns true.

Just like how your unit death trigger fires the condition when a unit dies.

The callback must have KT_GetData called exactly once.

 

[Lyerae]

Okay, that makes sense.
Thanks for explaining.

Geez that's useful...
JASS has no way to replicate easily this process? (awkward english in an attempt not to "split the infinite")

I assume once the function returns true, it stops using processing power and no longer contributes to lag (in-game/computer lag)?

 

[Azlier]

If you give KT a period of 5, it will fire that function every 5 seconds until it returns true. After which, it stops calling the function.

Not sure if your intention was to answer my question...but my question still remains...

Do you know?

>I assume once the function returns true, it stops using processing power and no longer contributes to lag (in-game/computer lag)?
That is correct.

Think of it kind of like this.

Let's say you have a function which takes an integer and then returns whether or not it should terminate, or be called again the same amount of time later.

Like imagine if you could have a timer that used a function that took an integer, an integer which you defined when you started the timer!

That's KT2.

Except instead of literally taking an integer, the integer is obtained by calling [LJASS]KT_GetData()[/LJASS].

Return true is like pause & destroy timer.
Return false is like do nothing.

Hope that helps.

 

[ZakkWylde-]

So it could be recreated in JASS then?

 

[Azlier]

What do you mean? Vanilla Jass? Well, yeah. With lots and lots of globals. And work.

 

[Lyerae]

function Callback takes nothing returns boolean
    local integer Data = KT_GetData()
    local boolean b = false
    call BJDebugMsg("Just a test, to see if I'm actually doing this right...")
    if b == true then
        return true
    endif
    return false
endfunction

function Stuff takes nothing returns nothing
    call KT_Add(function Callback, 0, 1)
endfunction
function myFunct takes nothing returns nothing
    local trigger t = CreateTrigger( )
    call TriggerAddAction(t, function Stuff)
endfunction

Am I doing it right?

 

[Azlier]

I suppose so.

Remember, if you don't actually need the data, just call KT_GetData().

 

[Lyerae]

Okay, cool.

Alright... Just tested.... And it did nothing...
Yeah, it hates me.
