Getting item position in bags

How would I get the item position of an item in my bags, I need to check the cooldown of an item that will have it's position changed regularly

iirc, you'll need to scan through each bag slot until you find the item you're looking for.

Does this help at all?

Yea, I looked at everything I could find through google but I'm not sure how I would scan through the bags yet

Lua Code:

-- Hearthstone
local itemID = 6948
 
for i = 0, NUM_BAG_SLOTS do
    for z = 1, GetContainerNumSlots(i) do
        if GetContainerItemID(i, z) == itemID then
            local _, duration = GetContainerItemCooldown(i, z)
            if duration == 0 then
                print ("Item is ready!")
            else
                print ("Cooldown is "..duration)
            end
            break
        end
    end
end

The code iterates over every container slot in every bag until it finds a match to the defined item ID. Once matched, the cooldown for the item is polled. If the cooldown returns 0, the item is off of cooldown; else the cooldown value is printed.

You'll need to adapt it to your needs; and I doubt the duration will return in a favorable format, likely seconds. You'll need to format it to hh:mm:ss etc.

Edit: I am not sure how to break out of nested loops in Lua, the code may be able to be optimized a bit if someone sheds some light on that aspect.

You're better off using itemlinks and a function to get the position, links are more accurate.

Lua Code:

local function GetBagPosition(itemLink)
    for bag = 0, NUM_BAG_SLOTS do
        for slot = 1, GetContainerNumSlots(bag) do
            if(GetContainerItemLink(bag, slot) == itemLink) then
                return bag, slot
            end
        end
    end
end
 
-- Get bag position of the Hearthstone
local _, itemLink = GetItemInfo(6948)
local bag, slot = GetBagPosition(itemLink)

Thanks for the replies guys but I just literally found out that GetItemCooldown does exactly what I need =) Your code snippets are a lot of help aswell though!

What you'd have to end up doing is set a variable in the inner loop for a conditional in the outer loop to check for and break out if needed. The following example has the dual purpose of getting the position and breaking out of both loops when it's found.

Lua Code:

--  Example of an item link
local _,link=GetItemInfo(6948);
 
local bag,slot;--   These are nil to start with
for i=0,NUM_BAG_SLOTS do
    for j=1,GetContainerNumSlots(i) do
        if GetContainerItemLink(i,j)==link then
            bag,slot=i,j;-- Set vars
            break;--    Breaks out of inner loop
        end
    end
 
--  Break out of outer loop if vars have been set by inner loop
    if bag and slot then break; end
end

Oh, that's easy enough. Thanks for the insight SDPhantom!
