Get itemAppearanceModID from item link?

[sezz]

Does anyone know get/parse the itemAppearanceModID from an item link?

GetInventoryItemID returns it for equipped items, but I need to get it from a link. (wowprogramming doesn't list it, only found it because @p3lim posted about it here)

Some sample links (yes they are Legion links, but itemAppearanceModID already exists in WoD):

Heroic gloves:
|cffa335ee|Hitem:124154::130219::::::103:63:4:5:2:564:566:531:::|h[Gloves of the Arcanic Conclave]|h|r
itemAppearanceModID: 1

Crated bracers, 6x upgraded:
|cffa335ee|Hitem:114814::::::::103:63:4:13:3:618:537:80:531:::|h[Hexweave Bracers of the Peerless]|h|r
itemAppearanceModID: 8

Don't think you can.

Can someone please move this thread to the Legion forum?

I need it for PlayerHasTransmog:

C_TransmogCollection.PlayerHasTransmog(itemID[, itemAppearanceModID])

Edit:

I didn't really raid in WoD, but from my tests with my limited items available I got:

0: Normal
1: Heroc
3: Mythic
8: Crafted item with 6 upgrades

for i=1,18 do print(select(2,GetInventoryItemID("player", i)), GetInventoryItemLink("player", i)); end

Will copy some materials later to the Beta realm to test id with all upgrade stages...

What are you going to do with it? How are you going to use it? You could plausibly "reverse engineer" the wardrobe data to get what you want. I seem to recall itemAppearanceMod being rather unreliable. Inconsistent across different items, but I'm not entirely sure.

Blizzards adds TRANSMOGRIFY_TOOLTIP_APPEARANCE_UNKNOWN only to item tooltips when the player can equip it. When playing on a mage for example there's no indicator if the appearance is already known on plate/mail/leather items - PlayerHasTransmog works accountwide and for all items.

I also use it for selling known transmog boe items, mailing unknown items and things like that.

True, but caching all availble appearances (~3300 only for items available to my shaman) seems like overkill to me for the simple stuff I'm trying to do And I don't see a way to get ALL items, it's just mail on a shaman for armor.

Ah, that's neat.

After some brief testing I may have been mistaken about appearance ID being unreliable. I might have been thinking of when I wanted to map them to bonus IDs, which are different for each expansion or something. Mythic Siege of Orgrimmar bonus ID is different than Warlords of Draenor mythic. Would be great if we could get these appearance IDs confirmed.

[Lombra]

The same IDs seem to be used for Siege of Orgrimmar items. Crafted WoD items starts at 6. Stage 3 through 6 looks the same, so it makes sense that stage 6 is ID 8.

Edit: Ok here's a less-than-ideal thing that might do. :P You can create a dummy dressup frame, try on an item and then do model:GetSlotTransmogSources(slot)! This gives you the wardrobe source ID for that particular item. (plus a second return value 0 for the few items I tried) You can then use that with C_TransmogCollection.GetAppearanceInfoBySource.

Interesting, I tried that and found out that Blizzard adds TRANSMOGRIFY_TOOLTIP_APPEARANCE_UNKNOWN to item tooltips even if they don't have a usable appearance (appearanceIsUsable = false, tested it with crafted 715+ itemlevel crafted cloth armor), but C_TransmogCollection.GetAppearanceInfoBySource still returns nil for cloth on my demon hunter and shaman.

I created a thread on the beta forums, maybe Blizzard listens. If not, we can still parse the item link and hope they never change the IDs for heroic/mythic/crafted upgrades

That is unfortunate. What about C_TransmogCollection.GetAppearanceSourceInfo? That returns some stuff. The fifth return value is a boolean unknown to me. Can't find any reference to it, but it looks like it could be "isOwned". The very small sample size of three of my items tested with this pointed towards it being so.

Also, I'm stupid. Since you do need to map the bonus IDs to appearance mod IDs, it will be unreliable/inconsistent, after all. :P

I'm in need of this, as well. I would much prefer not having to involve the annoying bonus IDs.

This is what I've found in the UI source:

local categoryID, appearanceVisualID, canEnchant, texture, isCollected, itemLink, appearanceLink, unknownNumber = C_TransmogCollection.GetAppearanceSourceInfo(appearanceSourceID);

It seems to work well when inspecting other players or with items on the AH

This is the code I used for testing, will do some tests later on other characters when I'm back:

-- Lua API
local strfind, strmatch, tonumber, select = string.find, string.match, tonumber, select;
 
-- WoW API/Constants
local IsDressableItem, GetItemInfo = IsDressableItem, GetItemInfo;
local TRANSMOGRIFY_TOOLTIP_APPEARANCE_UNKNOWN, TRANSMOGRIFY_TOOLTIP_APPEARANCE_KNOWN = TRANSMOGRIFY_TOOLTIP_APPEARANCE_UNKNOWN, TRANSMOGRIFY_TOOLTIP_APPEARANCE_KNOWN;
 
-- Text
local tooltipAppearanceUnusable = "You can't collect this appearance";
local tooltipSuffix = " (*)"; -- Makes it easier to tell if Blizzard added the text or we did...
 
-----------------------------------------------------------------------------
-- Hidden DressUpModel
-- TODO: Use C_TransmogCollection.PlayerHasTransmog(itemID[, itemAppearanceModID]) when Blizzard finally decides to give us access to itemAppearanceModID for all items.
-----------------------------------------------------------------------------
 
local model = CreateFrame("DressUpModel");
local lastItem, lastResult;
 
-- I'm not sure if invisible frames impact game performance, resizing it just in case...
-- Can't :Hide() the frame, because it doesn't seem to "equip" items when hidden.
model:SetSize(1, 1);
 
local PlayerHasTransmog = function(item)
    if (not model.isPlayer) then
        model:SetUnit("player");
        model:Undress();
        model.isPlayer = true;
    end
 
    if (lastItem and lastItem == item) then
        -- Tooltip update, reuse last results
        return lastResult;
    end
 
    local isCollected = false;
 
    model:TryOn(item);
 
    -- TODO: Get correct slot using GetItemInfo
    for i = 1, 18 do
        local appearanceSourceID = model:GetSlotTransmogSources(i);
        if (appearanceSourceID and appearanceSourceID > 0) then
            isCollected = select(5, C_TransmogCollection.GetAppearanceSourceInfo(appearanceSourceID)) or false;
            break;
        end
    end 
 
    model:Undress();
 
    -- Cache results, TODO: Update it on transmog event, if there is one?

        end
        return;
    end
 
    local equipSlot = select(9, GetItemInfo(itemLink));
    if (equipSlot == "INVTYPE_NECK" or equipSlot == "INVTYPE_FINGER" or equipSlot == "INVTYPE_TRINKET") then return; end
 
    if (PlayerHasTransmog(itemLink)) then
        self:AddLine(TRANSMOGRIFY_TOOLTIP_APPEARANCE_KNOWN..tooltipSuffix, 170/255, 255/255, 126/255);
    else

Old bonus IDs are known I think, but I'd rather have a solution that doesn's need updating everytime they decide to add new ones.

[Lombra]

Ah, must've missed that. Awesome!

Seems like a useful addon if it does what I think. I'm always uncertain of what it means when there's no info in the tooltip...

[Aadä]

Since last year, does Blizzard now allows us to get itemAppearanceModID number or not ?
I don't see how figuring out itemAppearanceModID for staged items without testing inputs manually which is not ideal at all
I know the number starts at 0, but I'm not even sure what's the limit, 8 ? 12 ?

[Lombra]

Yes. You can now retrieve the modifier ID using C_TransmogCollection.GetItemInfo.

[Aadä]

thanks.
though /dump C_TransmogCollection.GetItemInfo("shift clicked item") doesn't seem to return anything looking like the researched number. it should probably be a number lower than 10

also I can't seem to understand the behaviour of some items, especially the different versions of gear found in wod dungeons, like [Legguards of Burning Focus] from Mythic (id 109809 for every items called like that), if you go into the dungeon journal and link it in the script, it'll show empty result, only for the mythic versions

like, if you have the mythic version and you type /dump C_TransmogCollection.PlayerHasTransmog(109809,0) it'll show true, replace 0 by anything between 1 and 10, it'll always show false

how is that possible ? how does the game successfully prints missingTransmogSourceInItemTooltips with a different value for each version ?

does that mean PlayerHasTransmog is not the only function a collector will need to check ?
or maybe PlayerHasTransmog use a combination of item id+item version+another number to determine if a given item is a unique wardrobe entry

I suppose they didn't planned to get a transmog system when making wod judging by the mess : P
