Help with Custom Addon

[matthewyanek]

I am working on transferring some simple functions I use in wow into a custom add-on using LUA. Im trying to make a custom button that shows my hearthstone. When I click the button it casts my hearthstone, but where the issue is, is that I'm trying to have an overlay that shows the cooldown of my hearthstone. The button works fine, but the cooldown starts on entering world, and not on the cooldown of the item. Any help would help tremendously.

Here is the code that I am using for the button, and what I've come up with for the cool down using what I've found online:

local Hearth = CreateFrame("Button", "Hearth", UIParent, "SecureActionButtonTemplate")
Hearth:SetWidth(25)
Hearth:SetHeight(25)
Hearth:SetPoint("BOTTOMLEFT", UIParent, "BOTTOMLEFT", 3, 3)
Hearth:SetFrameStrata("HIGH")
Hearth:SetFrameLevel(1)
Hearth:RegisterEvent("UNIT_SPELLCAST_SUCCEEDED")
Hearth:SetNormalTexture("Interface\\ICONS\\ACHIEVEMENT_GUILDPERK_HASTYHEARTH")
Hearth:SetAttribute("type", "item")
Hearth:SetAttribute("item", "The Innkeeper's Daughter")
Hearth:RegisterForClicks("AnyUp")
Hearth:SetScript("OnEvent", function()
if IsUsableItem("The Innkeeper's Daughter")
then Hearth:Show() else Hearth:Hide()
end
end)
local HearthCD = CreateFrame("Cooldown", "HearthCD", Hearth)
local start, duration, enabled = GetSpellCooldown("The Innkeeper's Daughter")
HearthCD:SetAllPoints(Hearth)
HearthCD:SetCooldown(GetTime(), "900", 1)

UNIT_SPELLCAST_SUCCEEDED fires when anyone around you casts a spell, so we need to narrowing down what you want your function to react to specifically
, also your cooldown timer will start ticking when you enter the world as it is outside of the function

my coding is a bit rusty, so hopefully this might work:

local Hearth = CreateFrame("Button", "Hearth", UIParent, "SecureActionButtonTemplate")
Hearth:SetWidth(25)
Hearth:SetHeight(25)
Hearth:SetPoint("BOTTOMLEFT", UIParent, "BOTTOMLEFT", 3, 3)
Hearth:SetFrameStrata("HIGH")
Hearth:SetFrameLevel(1)
Hearth:SetNormalTexture("Interface\\ICONS\\ACHIEVEMENT_GUILDPERK_HASTYHEARTH")
Hearth:SetAttribute("type", "item")
Hearth:SetAttribute("item", "The Innkeeper's Daughter")
Hearth:RegisterForClicks("AnyUp")

if IsUsableItem("The Innkeeper's Daughter")
then Hearth:Show() else Hearth:Hide()
end

local HearthCD = CreateFrame("Cooldown", "HearthCD", Hearth)
HearthCD:SetAllPoints(Hearth)

Hearth:RegisterEvent("UNIT_SPELLCAST_SUCCEEDED")

local function eventhandler(self, event, unit,spellname)
    if (unit == "player") and (spellname == "Hearthstone") then
        HearthCD:SetCooldown(GetTime(), 900, 1)
    end
end

Hearth:SetScript("OnEvent", eventhandler);

I'm not sure if UNIT_SPELLCAST_SUCCEEDED actually works for the Hearthstone - generally, if you're interested in cooldown specific information, registering for an actual cooldown event such as BAG_UPDATE_COOLDOWN is the best way to go.

HearthCD:SetScript("OnEvent",function(self)
    local start,duration,enable=GetItemCooldown(64488)
    if enable then
        self:SetCooldown(start,duration)
    end
end)
HearthCD:RegisterEvent("BAG_UPDATE_COOLDOWN")
