Btw it can be custom easily with the jasshelper.

function main() -> InitBlizzard() ->InitMapRects()

function InitMapRects takes nothing returns nothing
set bj_mapInitialPlayableArea = Rect(GetCameraBoundMinX()-GetCameraMargin(CAMERA_MARGIN_LEFT), GetCameraBoundMinY()-GetCameraMargin(CAMERA_MARGIN_BOTTOM), GetCameraBoundMaxX()+GetCameraMargin(CAMERA_MARGIN_RIGHT), GetCameraBoundMaxY()+GetCameraMargin(CAMERA_MARGIN_TOP))
set bj_mapInitialCameraBounds = GetCurrentCameraBoundsMapRectBJ()
endfunction

For the smallest map possible, 32*32 :

So calculate yourself how many iterations your loop will do, it's pretty huge...

"Irritated" NOT MY CALCULATION "End"

What ?

This is a small dummy recycling system i made (took 10 min),its just a simple stack of units and very easy to use. any suggestions or idéa's are welcome :)

Dummy Recycling

library DummyRecycling initializer Init

globals
    private constant real WAIT_TIME = 1. //time to wait before "removing" a dummy
    private constant integer Dummy_id = 'hfoo' //dummy rawcode
    private constant integer ARRAY_SIZE = 20 //Max Number of Dummy's (u dont need so many)
    private unit array Dummys [ARRAY_SIZE]
    private integer Total = 0
    private integer Index = 0
endglobals

function CreateDummy takes player P, real x,real y returns unit
    if Total < ARRAY_SIZE then // if the stack isnt full we create or move a unit
        if Index >= Total then //if there no free units we create more
            set Dummys[Index] = CreateUnit(P,Dummy_id,x,y,0.)
            call UnitRemoveAbility(Dummys[Index],'Amov')
            set Total = Total + 1
            set Index = Index + 1
        else //else we move one
            call SetUnitX(Dummys[Index],x)
call SetUnitY(Dummys[Index],y)
            call SetUnitOwner(Dummys[Index],P,false)
            set Index = Index + 1
        endif
        return Dummys[Index-1]
    debug else
debug call BJDebugMsg("To many dummy's, increase the ARRAY_SIZE")
    endif

    return null
endfunction

function CreateDummyLoc takes player P, location loc returns nothing
    call CreateDummy(P,GetLocationX(loc),GetLocationY(loc))
    call RemoveLocation(loc)
    set loc = null
endfunction

function ReleaseDummy takes unit u returns nothing //this just change the owner of the dummy (maybe we should move them some where?)
    if GetUnitTypeId(u) == Dummy_id then
            call TriggerSleepAction(WAIT_TIME) //maybe use a timer instead?
            call SetUnitOwner(u,Player(15),false)
            set Index = Index - 1
        debug else
        debug call BJDebugMsg("function RemoveDummy: Unit given is not a Dummy Unit")
    endif
endfunction

private function Init takes nothing returns nothing
    set Dummys[Index] = CreateUnit(Player(15),Dummy_id,0.,0.,0.)
    call UnitRemoveAbility(Dummys[Index],'Amov')
    set Total = Total + 1
endfunction

endlibrary

e.g of usage

set Temp = CreateDummy(GetOwningPlayer(GetTriggerUnit(),0.,0.)
//dummy stuff
call ReleaseDummy(Temp)

well im in a rush so can't write more (ill get back later)

I don't really get why one would need a dummy recycling system, if you think about it, you only ever need the amount of units to be used when they are used, holding more just uses space, like a leak.

Unless it takes more memory to create unit than it does to run all of those functions to store an already created one, I really don't know, but I feel like the memory usage is from the presence of the unit, not its coming into usage.

EDIT - Something I just thought up, used for calling code without using TriggerEvaluate(), while avoiding constantly destroying the triggers you use

library CallCode
globals
    private trigger T = CreateTrigger()
    private conditionfunc C
    private boolean B
endglobals
function CallCode takes code c returns boolean
    set C = TriggerAddCondition(T, Condition(c))
    set B = TriggerEvaluate(T)
    call TriggerRemoveCondition(C)
    return B
endfunction
endlibrary

Ciebron · 08-22-2008, 03:15 PM

i can see no use for the function

ShaDowPoWeR · 08-23-2008, 04:44 AM

here is a little function, probably leaked because i am a noob but works ingame perfectly, removes a unit in a period of time like native UnitApplyTimedLife... this function's proper way to use is after death of an unit to clean it faster for example whenever death animation ends of an special effect dummie unit so you don't have to use buggy waits. (pause game doesn't affect waits)

Requieres handle vars

function RemoveUnitTimer takes nothing returns nothing
local timer T = GetExpiredTimer()
local unit U = GetHandleUnit(T, "u")
local real duration = GetHandleReal(T, "dur")
if duration > 0.05 then
call SetHandleReal(T,"dur", duration-0.05)
else
call RemoveUnit(U)
call FlushHandleLocals(T)
endif
endfunction
function AddRemoveUnitTimer takes unit U, real duration returns nothing
local timer T = CreateTimer()
call SetHandleReal(T,"dur", duration)
call SetHandleHandle(T,"u", U)
call TimerStart(T,0.05,true, function RemoveUnitTimer)
set T = null
endfunction

If you create a locusted unit at (x, y), the unit will consider pathing (as if it didn't have locust) (EDIT: at the moment of its creation). This can be avoided by moving the unit with SetUnitX/Y right after.

Herman · 08-25-2008, 06:43 PM

Oh, that sounds really good

Like, if you had a projectile that had locust, and then sent it on its path without using the X/Y, the locust would move all f*cked up when it got to a cliff or something, but if you first use the X/Y, then it will do it cleanly?

(I don't have war3 isntalled on this comp, but I would very very much appreciate somebody checking that for me)

I tried to create a unit with locust at the position of a normal unit, but the locusted unit appeared on the side of it, not 'inside' it like it would if I had moved it there with SetUnitX/Y.

(forgot to mention in my earlier post that I was only talking about the moment of creation)

Herman · 08-26-2008, 05:29 PM

But, if you use SetUnitX/Y, it will get 'inside it' ?

Yep.

I improved upon my old timer. Hopefully you like this one.

Herman · 10-20-2008, 12:38 PM

Errr, when would you need to check just one integer variable?

I think as a concept this is ok, but as code to be used, this isn't too useful as a debugging tool unless you could specify the array being checked, converting it to a textmacro may be helpful

Herman · 10-21-2008, 11:35 PM

If its buggy shit why would you post it?
