Uniquely Identifying Items

Hey all,

I'm making an addon for Classic and need a way to uniquely identify soul shards Warlocks create in their bags. I've read through the API and couldn't really find anything. The best solution I came up with was using the bag number and slot number to map to corresponding soul shards.

This approach however ran into its own issue. I would like to use the tooltip widget to hover over a soul shard and display information unique to that specific soul shard. The problem is the tooltip functions provide no way of getting the bag index/slot index of the item you're hovering over.

I could get this information if the user selects (locks) a soul shard from the inventory, but that's not the solution I'm looking for.

Thanks!

If the GameTooltip is showing for an item then the mouse is still over that item so you can use GetMouseFocus:

Code:

local focus = GetMouseFocus()

if not (focus:GetName() or ""):match("ContainerFrame%d+Item%d+") then return end

local bagID, slotID = focus:GetParent():GetID(), focus:GetID()

-- Do something with bagID, slotID

Sounds like a fun personal project I made a while ago that tracks who's soul a shard is created from.
It even shows the origin of the shard used to create healthstones, soulstones, and even summoned demons.
It also works on generic item tooltips, meaning ActionButton tooltips work.

classic has the item api retail uses, at least according to the code extract. Here's what I use in a retail weakaura to track and loot openable looted items:

Lua Code:

if event=="BAG_UPDATE_DELAYED" then
    if not aura_env.combat and not InCombatLockdown() then
        for b=BACKPACK_CONTAINER,NUM_BAG_SLOTS do
            for s=1,GetContainerNumSlots(b) do
                if GetContainerItemID(b,s)==45724 then
                    aura_env[(Item:CreateFromBagAndSlot(b,s):GetItemGUID())]=1
                    UseContainerItem(b,s)
                end
            end
        end
    end
elseif event=="LOOT_OPENED" then
    for i=GetNumLootItems(),1,-1 do
        if aura_env[(GetLootSourceInfo(i))] then
            LootSlot(i)
        end
    end
end

The bag update event opens the specific openable I'm tracking while saving that bag's GUID, then the loot opened event checks the loot source and if it's a guid I saved, autoloot it all.

That does sound like fun. It would be cool if you modified the tooltip to say "Fred's soulstone" or had random emotes saying "Let me go". :)

This is pretty much what it does. :D

Would you be willing to share it? I play a warlock and this would add so much to the class play.

Sure. It's just prototype code atm. I'll get it uploaded once I get it into a more polished state.
