Item exists in inventory or bank best practice

Argusus · 06/22/15, 08:34 AM

Hello, I was wondering if there is a best practice or efficient way to check the existence of an item in someone's bank or in their inventory bag. I haven't done this before. I would have the item link for the item I'm looking for, I'm just not sure how to check for existence.

I can't tell "best practice" but any function will do same thing in background. Will reach to bag, bank etc and search item in your conditions...

Code:

local bagId = BAG_BACKPACK
-- check: http://wiki.esoui.com/Constant_Values#BAG_BACKPACK
local bagSlots = GetBagSize(bagId) -1
for slotIndex = 0, bagSlots do
    local itemType = GetItemType(bagId, slotIndex)
    local link = GetItemLink(bagId, slotId)
    local itemID = select(4,ZO_LinkHandler_ParseLink(link))
    if itemID == xxxx and itemType == blabla then
    -- code goes here
    end
end

Sorry for bad English, but basically any function will do this in background like i said.

Regards

Please avoid

Lua Code:

local bagSlots = GetBagSize(bagId) -1
for slotIndex = 0, bagSlots do
    local itemType = GetItemType(bagId, slotIndex)

to itarate bags.

Use :

Lua Code:

local bagCache = SHARED_INVENTORY:GenerateFullSlotData(nil, BAG_BACKPACK)
for slotId, data in pairs(bagCache) do

instead.

1st, the first snipped don't really work work Guild Bank.
2nd, sometimes , it don't work neither in bag. (even it's more rare).

And most of all, please consider that slotIndex is data.slotIndex and not in the key.
