Hello,

I have a problem with my tiny addon I made. I get error while its event get triggered by multiple tooltip at once.
eg. when you put your mouse on inventory items while switch it and it show other options

This is my event handler so far:

TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Item, GetItemGCDInfos)

The error is:

attempt to call method 'GetItem' (a nil value)

it is refering at the function I use to get spell gcd from items. It works for the "main" tooltip, but throw the error for the other ones



And this is my whole code for the sake of this post:

local gcdMS, gcdMSControl, cooldownMS, displayedName, spellID, ItemName, ItemLink, gcdText
 
local function MSround(num, numDecimalPlaces)
  local mult = 10^(numDecimalPlaces or 0)
  return math.floor(num * mult + 0.5) / mult
end
 
local function SetNewLineWithGCD(tt,gcdMS)
        gcdMS = MSround(gcdMS / 1000,2)
        gcdText = ""
        gcdText = "GCD "..gcdMS.."sec"
        tt:AddLine(" ",1,1,1)
        tt:AddLine(gcdText,0,1,0)
end
 
local function GetSpellGCDInfos(tt)
    gcdMS, cooldownMS, spellID = nil
    
    _, spellID = tt:GetSpell()
    if spellID ~= nil then
        cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
    end
 
    if gcdMS ~= nil then
        SetNewLineWithGCD(tt,gcdMS)
    end
end
 
local function GetItemGCDInfos(tt)
    gcdMS, cooldownMS, spellID, ItemLink = nil
    
    _, ItemLink = tt:GetItem()
    _, spellID = GetItemSpell(ItemLink)
    
    if spellID ~= nil then
        cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
    end
    
    if gcdMS ~= nil then
        SetNewLineWithGCD(tt,gcdMS)
    end
end
 
local function GetMacroGCDInfos(tt)
    gcdMS, cooldownMS, displayedName, spellID, itemName, ItemLink = nil
    
    displayedName = _G[tt:GetName().."TextLeft"..1]:GetText()
    _,_,_,_,_,_,spellID = GetSpellInfo(displayedName)
    
    if spellID ~= nil then
        cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
    else
        _,ItemLink = GetItemInfo(displayedName)
        _, spellID = GetItemSpell(ItemLink)
        if spellID ~= nil then
            cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
        end
    end
    
    if gcdMS ~= nil then
        SetNewLineWithGCD(tt,gcdMS)
    end
end
 
TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Spell, GetSpellGCDInfos)
TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Item, GetItemGCDInfos)
TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Macro, GetMacroGCDInfos)
