Simple question

Flame_Phoenix	Hi guys, I have a global item array. The problem here is that I need to pass it as an argument to another function. Is there a way I can do it ?

the-thingy	You want to pass the whole array? You could take the topmost used array index as a parameter, and loop through all items from 0 to parameter i.e. JASS: function LoopThroughArray takes integer topIndex returns nothing local integer i = 0 loop exitwhen i > topIndex call DoSomethingWithArray (variable[i]) set i = i + 1 endloop endfunction

JASS:

type ItemArr extends item array[500]

globals
    ItemArray anArray
endglobals

function bar takes ItemArr IA returns nothing
    call ShowItem( IA[2], false )
endfunction

function foo takes nothing returns nothing
    set anArray = ItemArr.create()
    call bar( anArray )
endfunction

Flame_Phoenix	Oh, I can't use vJASS btw .... And I need to pass the array, or at least an identifier of it. My main problem is that I have 3 item arrays and I have code to manage them. However, the code doesn't know which array to change, and it must know. Is there a way to define an identifier for a global array that can be used as a parameter ? Like if I receive parameter A I know I must change array A =S

Gwypaas	make the function take an extra integer and then make the function use ifs to compare the integer and then use the right global array. like JASS: function SomeFunction takes integer n returns nothing if n == 1 then call DoSomeThingWithArrayA() elseif n == 2 then call DoSomethingWithArrayB() ...... endfunction

the-thingy

So, you want to handle one of X arrays within the same function?

JASS:

function HandleItemArrayOne takes integer topIndex returns nothing
  local integer i = 0
  loop
  exitwhen i > topIndex
    call DoSomethingWithArray (variableOne[i])
    set i = i + 1
  endloop
endfunction
//And something identical for the other ones you need
//Or, see next JASS box

function HandleArray takes integer id, integer topIndex returns nothing
//Pretty much what Gwy did, except with a bit more excess above
  if id == 1 then
    call HandleItemArrayOne (topIndex)
  elseif id == 2 then
    call HandleItemArrayTwo (topIndex)
  elseif id == 3 then
    call HandleItemArrayThree (topIndex)
  endif
endfunction

Alternatively

JASS:

function HandleArray takes integer id, integer topIndex returns nothing
  local item array items
  local integer i = topIndex
  loop
  exitwhen i == 0
    if id == 0 then
      set items[i] = variableOne[i]
    elseif id == 1 then
      set items[i] = variableTwo[i]
    elseif id == 2 then
      set items[i] = variableThree[i]
    endif
    call DoSomethingWithItem (items[i])

    set items[i] = null
    set i = i - 1
  endloop
endfunction

If I'm understanding you correctly

Then, when removing items from the array (so that you're only looping through in-use values)

JASS:

set variableOne[thisItemsIndex] = items[Top]
set Top = Top - 1

Anitarf	Try simulating a 2D array? Like, use one array variable for all of them, and then have indexes from 0 to 999 for array A, 1000 to 1999 for array B etc.

Quite useless if we keep in mind functions can't receive arrays as parameters.

Anyway, I found a solution, thx guys !

dead_or_alivex	Order it to cast the spell that the custom spell is based off.

Second thread hi-jack, and on the same question as before: http://www.wc3campaigns.net/showthread.php?t=103074

please learn to read the forums before you ask for help, and for the love of god, don't steal other people's threads.

you would pass an integer and it would provide you with the starting point in the master array

JASS:

integer array Items
// 0-999 is array 0
// 1000-1999 is array 1
// 2000-2999 is array 2
// etc..

function DoSomethingWithArray takes integer arrayNumber, integer slot returns nothing
    set slot = slot*1000 // 0 will start at 0, 1 will start at 1000, etc..
    set Items[slot+arrayNumer] = someVal
endfunction

function Test takes nothing returns nothing
    call DoSomethingWithArray(0, 50) // array 0, slot 50
    call DoSomethingWithArray(3, 250) // array 3, slot 250
    call DoSomethingWithArray(4, 1222) // array 5, slot 222
    // careful when doing stuff outside of the size of the smaller arrays.
endfunction
