Countdown Timers for Events

[Demonfaze]

How exactly do you use Countdown Timers for Events? I can't seem to get it working properly.

Here is my code

tmr_ROUNDTIMER = global timer variable
tmr_ROUNDTIMERDIALOG = global timer dialog variable

Trigger 1: Setting up the timer

set tmr_ROUNDTIMER = CreateTimer()
        call StartTimerBJ(tmr_ROUNDTIMER, false, 5 )
        call CreateTimerDialogBJ( tmr_ROUNDTIMER, "Prep Time" )
        set tmr_ROUNDTIMERDIALOG = GetLastCreatedTimerDialogBJ()

Trigger 2: Event from the timer

function Trig_Start_Round_Trigger_Actions takes nothing returns nothing

    call showMessage(5, "Timer Expired")

endfunction

//===========================================================================
function InitTrig_Start_Round_Trigger takes nothing returns nothing
    set gg_trg_Start_Round_Trigger = CreateTrigger(  )
    call TriggerRegisterTimerExpireEventBJ( gg_trg_Start_Round_Trigger, tmr_ROUNDTIMER )
    call TriggerAddAction( gg_trg_Start_Round_Trigger, function Trig_Start_Round_Trigger_Actions )
endfunction

The timer displays, so I know the first block of code works. The second trigger, however, doesn't appear to fire off.

Thanks in advance.

I'm not sure, but I think it is because you create tmr_Roundtimer after the trigger has been registered, so the event is tied to <No timer>.

Hint: You can replace any function that has BJ in it with a faster function.

That sounds possible. Do you know how I can fix this?

Thanks in advance.

should't it have then the prefix udg_ if it's global?

and also this event is created on the initialization so you have to make sure it is set before the event is being set

Sorry, I forgot to mention I'm using Newgen WE.

Splendid! Then Declare your timer in a globals block

globals
timer tmp_Whatevertimername = CreateTimer()
endglobals

then start your timer elsewhere.

EDIT: I fail.

 

[Demonfaze]

That's exactly what I had.

globals
timer tmr_ROUNDTIMER = CreateTimer()
endglobals

Using events with timers = pointless in Jass.
Jass offers you a thing called callback for this purpose. Consider the following code:

function foo takes nothing returns nothing
    call BJDebugMsg("test")
endfunction

function bar takes nothing returns nothing
    local timer t = CreateTimer()
    call TimerStart(t, 5., false, [B]function foo[/B])
endfunction

The message "test" will display 5 seconds after running bar. Also know that the timer has to be destroyed which I didn't do in the code above to keep it simple.
And avoid BJs in Jass. They're a very bad thing.

I'd like to use a timer though, so I can have the timer window displayed in-game.

You are using a timer in my code, but you aren't using a trigger.
You can just add call CreateTimerDialogBJ( t, "Prep Time" ) right below TimerStart and it will work fine.
It's a better idea to use natives for this purpose though, but either one works fine.

Well actually the only reason you would need them would be to make multiple triggers to use a single timer, like with a movement system or something of the sort.
