Having issue with C_MountJournal.GetMountFromItem in a simple addon

Guides UI and Macro

I made a very simple addon (almost as simple as “hello world”) that uses C_MountJournal.GetMountFromItem().

When I load the game, it either prints out the correct value of 2261 or the call doesn’t work and it prints out nil.
It doesn’t matter if I load the game or use /reload - it’s about 50/50 for a 2261 result or a nil result. Therefore, the issue isn’t directly related to initial game loading.

ahw.lua:

print(C_MountJournal.GetMountFromItem(228760))

If this call is not reliable 100% of the time, then I can’t use it for what I have planned.

Items need to be retrieved from the server and cached before you can get information from them. Try:

local item = Item:CreateFromItemID(228760)
item:ContinueOnItemLoad(function()
	print("Mount ID:", C_MountJournal.GetMountFromItem(228760))
end)

Thanks - that worked!

Since the argument to ContinueOnItemLoad() is a lambda function, is there a way I could pass the item ID (228760) to the function?
Eventually I’ll want the item ID to be a variable, so it won’t be hardcoded.

Would something like this be correct-ish?

local itemID = 228760
local item = Item:CreateFromItemID(itemID)
item:ContinueOnItemLoad(function(itemID)
	print("Mount ID:", C_MountJournal.GetMountFromItem(itemID))
end)

Depending on need, you could do something like:

local itemID
local function PrintMountID()
	print("Mount ID:", C_MountJournal.GetMountFromItem(itemID))
end

local function DoSomethingWithMount(itemid, action)
	itemID = itemid
	local item = Item:CreateFromItemID(itemID)
	item:ContinueOnItemLoad(action)
end

DoSomethingWithMount(228760, PrintMountID)
