Trigger when an item is placed in my inventory

[Eommus]

Hi,

Is there an event that is triggered when an item is placed in my inventory? The source can be anything, e.g.:

- looting a mob
- opening a chest or box
- opening mail
- trading with another player
- buying from a vendor
- crafting
- quest reward
...

simply any action that may place an item in your inventory.

If there isn't one single event to handle all these, which other events shall I need to register, in addition to LOOT_OPENED?

Basically, I want my addon function to trigger when my character gets a new item from external sources (excluding moving an item from one bag to another, from my personal bank, reagent storage or guild bank).

Thanks for any ideas.

I think Xloot already does this, have notif window like in GW2

You could check the chat-message-lock for loot-events and handle them in your weakaura

There are different events that fire depending on the situation.

There's one event that fires for looting a corpse. There might be 2-3 different events that fire if you craft something depending on what it is. A proc that generates an item on the side might be a different event. Completing a world quest kinda has its own ecosystem and might have its own event.

you have to use /eventtrace to hunt them down.

/eventtrace will pull up the event window in-game. shows you what events are firing.

/eventtrace stop
/eventtrace start

those will let you cut out the noise because sometimes there are a lot of events firing.

The BAG_UPDATE Event that fire when you put anything or move anything in your bag

The BAG_UPDATE Event that fire when you put anything or move anything in your bag

Thanks for the note, this might be what I can use. As usual, I seek the simplest method that would do the job. So, if there's one single event that will do the job, that will be enough.

http://wowprogramming.com/docs/events/BAG_UPDATE page says BAG_UPDATE event needs to be registered after PLAYER_ENTERING_WORLD, to prevent excessive processing at each UI load/reload. Is this how it is done?

local f = CreateFrame("Frame")
f:RegisterEvent("PLAYER_ENTERING_WORLD")
f:RegisterEvent("BAG_UPDATE")

local function My_Function()
	...
end

f:SetScript("OnEvent", My_Function)

Also, BAG_UPDATE requires a bag id, how do I find the bag ids for my inventory bags (5 of them) and how do I use that ids in my code? Unfortunately, I couldn't find any sample code explaining that.

If it would help, here is my current code, which is supposed to log (in a savedvariable lua file) the id of every item I obtain in the game from any source I listed in the OP.

LootLog = {}

local f = CreateFrame("Frame")
f:RegisterEvent("LOOT_OPENED")

local function Log_Loot()
	local n = GetNumLootItems()
	for i = 1, n do
		local item = GetLootSlotLink(i)
		local itemId = select(2, strsplit(":", itemLink, 3))
		
		table.insert(LootLog, itemId)
	end
end

f:SetScript("OnEvent", Log_Loot)

It works fine for "loot" type of item acquisition, I just want it to work for any type of item acquisition.

You would use

for bag = 0, NUM_BAG_SLOTS do                for slot = 1, GetContainerNumSlots(bag) do
          -- do stuff

You can see how its used (sort of) in the APUse WA's (https://wago.io/UseArtifactPowerIcon or https://wago.io/UseArtifactPower)

Thank you, I modified my code as:

LootLog = {}

local f = CreateFrame("Frame")
f:RegisterEvent("BAG_UPDATE")

local function Log_Loot()
	for bag = 0, NUM_BAG_SLOTS do
		for slot = 1, GetContainerNumSlots(bag) do
			local item = GetContainerItemLink(bag, slot)
			local itemName = select(1, GetItemInfo(item))
			
			table.insert(LootLog, itemName)
		end
	end
end

f:SetScript("OnEvent", Log_Loot)

I don't know if I am doing the loop correctly but it creates the same entry 183 times. Say, I acquired 1 item, it logs that item for 183 times. Then if I acquire another item, it logs those two items 183 times. I have backpack (16) plus 4 x 30 bags, 136 slots in total.

I ended up with the following code, which is more efficient than BAG_UPDATE and works just as I wanted (also, it does not create duplicate entries):

LootLog = {}
 
local f = CreateFrame("Frame")
f:RegisterEvent("CHAT_MSG_LOOT")
 
function Log_Loot(self, event, message, _, _, _, player, _, _, _, _, _, _, ...)
    if player == "Eommus" then
        local itemId = message:match("item:(%d+):")
        LootLog[itemId] = {}
    end
end
 
f:SetScript('OnEvent', Log_Loot)
