Hello,

I have made this to train myself

local gcdMS, gcdMSControl, cooldownMS, spellName, spellName, spellID, itemName, ItemLink, gcdText
 
_G["GameTooltip"]:HookScript("onShow",function(this)
 
    gcdMS, cooldownMS, spellName, spellName, spellID, itemName, ItemLink = nil
    spellName, spellID = this:GetSpell()
    itemName, ItemLink = this:GetItem()
 
    if spellID ~= nil then
 
       cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
       print("ID:"..gcdMS)
 
    elseif itemName ~= nil then
 
       spellName, spellID = GetItemSpell(ItemLink)
       cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
       print("spell from item link:"..gcdMS)
 
    else
 
       spellName = _G[this:GetName().."TextLeft"..1]:GetText()
       _,_,_,_,_,_,spellID = GetSpellInfo(spellName)
       cooldownMS, gcdMS = GetSpellBaseCooldown(spellID)
       print("spell with no ID:"..gcdMS)
 
    end
 
    gcdMS = round(gcdMS / 1000,2)
    gcdText = ""
    gcdText = "GCD "..gcdMS.."sec"
    -- I add the text to the current tooltip
    this:AddLine(gcdText,1,1,1)
end)

So I got this `AddLine` method. And when I'm in the game and I mouse over a spell, it shows the text but only for less than a second.

I tried to make it so it's in the `onUpdate` method, but it does the same

_G["GameTooltip"]:HookScript("onUpdate",function(this)
    gcdMS = round(gcdMS / 1000,2)
    gcdText = ""
    gcdText = "GCD "..gcdMS.."sec"
    this:AddLine(gcdText,1,1,1)
end)

Thank you
