Know Which Timer Expires Through A Conditional Comparison?

05-04-2007, 01:23 PM

i'm trying to figure out a way to do a timer compare. i have a timer with an array size of 10 and i am going to make a camera pan per each individual timer array expiring.

i really dont want to have 10 triggers that watch for each timer. is it possible to use conditions to see which trigger is the trigger that expires.

i was thinking of doing this: "for each integer a from 1 to 10".. then do an if then else with something like "if VarTimer(integer a) = Expiring timer.. then do"

but i can't seem to find something like this. the only thing i can find that references the "expiring timer" is if i did a "Real" comparison .. but i'm not looking for a real value.. i just want a timer comparison.. if timer is equal to timer.

is there no way to do this?

Vexorian	This is one of those reasons not to use GUI.

Earth-Fury	In JASS, you can get the exipred timer with the function GetExpiredTimer(). There is probobly an equivilent of this in GUI. (unless it only works in a TimerStart callback. in which case, learn JASS)

Brash	couldn't i just throw in a custom script? this way i dont have to make the whole thing jass.

Toink	You can't do it in GUI. In JASS, attach an integer(unique of course) to each timer. That way you can tell timers apart by reading the attached integer and checking whether it is integer X.

Anitarf	You could do it with a custom script as well. A timer comparison would look something like this: if GetExpiredTimer() == udg_yourTimerArray[GetForLoopIndexA()] then and endif, you would put this at the start and at the end of your loop actions. But it's really simpler to use JASS and atachable vars.

Toink	Oh that would work too XD You should get the hang with JASS, you can compare alot of stuff you can't in GUI and gives you a whole lot more..

i dont know what you mean by attaching an integer. how do you attach such a variable to another?

to Vexorian, Anitarf, and Earth-Fury:

although i'm not really familiar with jass I did try a convert trig to script and modified an existing condition check somewhat and came up with this and it let me save. whoo:

JASS:

function Trig_Pancam_Func001Func001C takes nothing returns boolean
    if ( not ( GetExpiredTimer() == udg_PanCamTimer[GetForLoopIndexA()] ) ) then
        return false
    endif
    return true
endfunction

function Trig_Pancam_Actions takes nothing returns nothing
    set bj_forLoopAIndex = 1
    set bj_forLoopAIndexEnd = 10
    loop
        exitwhen bj_forLoopAIndex > bj_forLoopAIndexEnd
        if ( Trig_Pancam_Func001Func001C() ) then
            call PanCameraToTimedLocForPlayer( GetOwningPlayer(udg_UnitVar[GetForLoopIndexA()]), udg_centerpoint, 1.50 )
        else
            call DoNothing(  )
        endif
        set bj_forLoopAIndex = bj_forLoopAIndex + 1
    endloop
endfunction

//===========================================================================
function InitTrig_Pancam takes nothing returns nothing
    set gg_trg_Pancam = CreateTrigger(  )
    call TriggerAddAction( gg_trg_Pancam, function Trig_Pancam_Actions )
endfunction

btw, this has no event cuz i'm using this trigger to add an event:

Trigger:

NonlocalCamTimer

Events

Map initialization

Conditions

Actions

For each (Integer A) from 1 to 10, do (Actions)

Loop - Actions

Trigger - Add to PanCam <gen> the event (Time - PanCamTimer[(Integer A)] expires)

Do not use the

JASS:

call DoNothing()

It is a waste and not needed. Instead do this..

JASS:

    loop
        exitwhen bj_forLoopAIndex > bj_forLoopAIndexEnd
        if ( Trig_Pancam_Func001Func001C() ) then
            call PanCameraToTimedLocForPlayer( GetOwningPlayer(udg_UnitVar[GetForLoopIndexA()]), udg_centerpoint, 1.50 )
        endif
        set bj_forLoopAIndex = bj_forLoopAIndex + 1
    endloop

If you have no actions for else then remove the else from the if-then-else structure. So it is actually just a if-then structure.

okay thx. wouldn't have known that.

what about the alternative way you mentioned with attaching an integer? how do you do this? is that like a custom value attached to a unit? can it be done in gui?

The alternative way is.. slower. It uses gamecache.

As for attachable vars, they are attached using handle vars, which are functions that can 'attach' a variable to another variable. It does that by using gamecache and stores it. If you want to be able to get that attached variable you call the handle vars functions and it returns that variable.

It was made to be able to use locals in more than one function.

JASS:

function MyOtherFunction takes nothing returns nothing
local timer t = GetExpiredTimer()
local unit u = GetAttachedUnit(t, "u")//Calls a function to get the unit 'called' "u" which is attached to the timer t)
endfunction

function MyFunction takes nothing returns nothing
local unit u = GetTriggerUnit()
local timer t = CreateTimer()
    call AttachObject(t, "u", u)//Calls a function which attaches the variable u to the variable t with the 'name' of "u".
    call TimerStart(t, 0.01, false, function MyOtherFunction)
    set u=  null
endfunction

Just a demonstration, but Anitarf's suggestion is a whole lot easier and faster..

wyrmlord	You need to get a feel for JASS before doing things like this. I would suggest taking a look at the various tutorials around the site for JASS.

05-04-2007, 03:54 PM	#13
Toink	That means "take a look at me and darkwulv's tutorials"

05-05-2007, 11:29 AM	#14
Anitarf	Actualy, no, I would say that means "look at Vexorian's Introduction to JASS".
