Item slot detection

[Gerional]

Hi guys.
I'm making item bank spell which will give you item from n slot when you'll use it.
But i need to make trigger that will replace item in the same slot if inventory is full.
There is any way to detect in which slot was item-target of spell? Becouse i didn't find any solution.
Thx

Blizzard didn't provide a direct function which returns the inventory slot of an item. Though, you can find that out by looping through a unit inventory and checking if a specific item is in slot X.

// Returns the inventory slot for a specific item
function GetItemSlotPosition takes unit whichUnit, item whichItem returns integer
    local integer slot = -1
    local item itm = null
    local integer i = 0
    loop
        exitwhen i == bj_MAX_INVENTORY
        set itm = UnitItemInSlot(whichUnit, i)
        if itm == whichItem then
            set slot = i
            exitwhen true
        endif
        set i = i + 1
    endloop
    set itm = null
    return slot
endfunction

Now that function will do the job. However, in JASS inventory slots range from 0 to 5 whereas in GUI it's from 1 to 6. If you are using GUI only, then I suggest you add +1 to the return line.
return slot
->
return slot+1

Example:

• Events
  • Unit - A unit Starts the effect of an ability
• Conditions
  • (Ability being cast) Equal to Whatever
• Actions
  • Set WhichUnit = (Triggering unit)
  • Set TargetItem = (Target item of ability being cast)
  • Custom script: set udg_ItemSlot = GetItemSlotPosition(udg_WhichUnit, udg_TargetItem)
  • -------- Keep in mind the function above "GetItemSlotPos" ranges from 1 to 6 --------
  • Game - Display to (All players) the text: (Slot: + (String(ItemSlot)))
