Why doesn't this piece of code work?

Hello, I have this code in my addon:

Code:

RegisterForEvent(EVENT_LOOT_RECEIVED, XL.OnItemLooted)  



                

function XL.OnItemLooted (numID, lootedBy, itemName, quantity, itemSound, lootType, self)



        bFound = false



        d (itemName)



        if (string.find(itemName, "Needle") ~= nil) then bFound  = true

        end



        -- Do something here

end

The above never detects the presence of the "Needle" string in the itemName. Why? The code seems correct.

1) I verified that the IF works by pre-injecting my own strings into itemName.

2) The d(itemName) displays correctly formed item link in chat.

How do I convert the itemName link to searchable string?
Thanks!

How exactly does itemName look like if the event callback function is triggered? What is in the variable? And what is shown if you post it to the chat using d(itemName)?

The event callback function parameters seem to be correct.
EVENT_LOOT_RECEIVED (integer eventCode, string receivedBy, string itemName, number quantity, number itemSound, number lootType, boolean self, boolean isPickpocketLoot, string questItemIcon, number itemId)

Is it a unicode issue?

No, it's the item's itemLink then, and not only the name of the item.
To get the item's name from that link use the function here:

Code:

* GetItemLinkName(*string* _itemLink_)

** _Returns:_ *string* _itemName_

Use it like this then:

btw: Is it correct that your variable "bFound" is a global one?
If you use global variables please create one global array for your addon's namespace like this

Code:

myAddonName = {}

and add your addon's variables to it then. Otherwise you might get in trouble if any other addon uses "bFound" too!

Code:

myAddonName.bFound = false

Lua Code:

RegisterForEvent(EVENT_LOOT_RECEIVED, XL.OnItemLooted)  
 
        
function XL.OnItemLooted (numID, lootedBy, itemLinkStr, quantity, itemSound, lootType, self)
 
    myAddonName.bFound = false
 
        d (itemLinkStr)
        local itemName = GetItemLinkName(itemLinkStr)
 
    if itemName ~= nil and (string.find(itemName, "Needle") ~= nil) then myAddonName.bFound  = true
    end
 
    -- Do something here
end

Thanks that function solved the problem.

As for the globals, I did use the "local" keyword but I removed it to make the code shorter here.
