spawning with integer

[Doran05]

Hi,

every x second map is spawning wagon. This wagon will move to some region and destroy itself.

now i want spawn 1 ghoul, every y second, for each wagon that reach region.

Can somebody help me and explain me how to do that?
thx

• Untitled Trigger 079
  • Events
    • Time - Every 1.00 seconds of game time
  • Conditions
  • Actions
    • Custom script: set bj_wantDestroyGroup = true
    • Unit Group - Pick every unit in (Units in region matching (((Unit-type of (Matching unit)) Equal to Wagon) and (((Matching unit) is alive) Equal to True))) and do (Actions)
      • Loop - Actions
        • Set point = (Position of (Picked unit))
        • Unit - Create 1 Ghoul for SomePlayer at point facing Default building facing degrees
        • Custom script: call RemoveLocation(udg_point)
        • Custom script: set udg_point = null

So null = RemoveLocation ?

So null = RemoveLocation ?

It will leak a bit if not nulled.

What I meant was, is there no need for the RemoveLocation(whichLocation) ?

Oh no, you must absolutely remove the location before nulling.
Nulling doesn't remove the stored value, so it will leak if you either don't remove the location, or if you remove it after nulling.

Also, Maker: most people don't null globals :/

I know, and they will leak :/

This is what DSG has to say about this topic:

If the global is constantly having its value changed, then nulling is a waste of time.

I'm not knowledgeable enough about the underlying mechanics to verify any of this, but his post does seem to make sense.

            call RemoveLocation(l)
            set k = k + 1
            set i = i - 1
            //set l = null
        endloop
    endfunction

    function Trig_Untitled_Trigger_001_Actions takes nothing returns nothing
        if udg_i == 0 then
            set udg_i = 1
            call BJDebugMsg("start")
            call TimerStart(udg_tmr, 0.01, true, function looping)
        else
            set udg_i = 0
            call BJDebugMsg("stop")
            call BJDebugMsg(I2S(k))
            call PauseTimer(udg_tmr)
        endif
    endfunction

    //===========================================================================
    function InitTrig_Untitled_Trigger_001_Copy takes nothing returns nothing
        local unit u
        set gg_trg_Untitled_Trigger_001_Copy = CreateTrigger(  )
        set u = CreateUnit(Player(15), 'hfoo', 0, 0, 0)
        call UnitApplyTimedLife(u, 1, 0.01)
        call TriggerRegisterPlayerEventEndCinematic( gg_trg_Untitled_Trigger_001_Copy, Player(0) )
        call TriggerAddAction( gg_trg_Untitled_Trigger_001_Copy, function Trig_Untitled_Trigger_001_Actions )
        set u = null
    endfunction
endlibrary

If the l = null is commented out, the memory usage of War3.exe grows constantly. If it is not commented out, the memory usage will not grow at all. It applies to globals also.
