Adding a gcd spark to a castbar

[Pyrates]

Hey there!

I'm trying to add a gcd spark to my castbar. Up to now, I've been using ouf_gcd by hungtar, but he discontinued support, and it stopped working (I guess because of the ouf update). Can anyone tell me how to do that now?

Have you tried to look at how he did it and tried to adept it right into your layout?

There are two problem with that: First it adds a separate bar, which I'm trying to avoid now (I want that spark inside the usual cast bar). Second, I don't really understand how. oUF_gcd adds a new element, and I can use elements (well, some), but I don't know how to make an element work in my layout that does not work because it's not compatible with the new ouf (that's what I assume... there are actually no lua errors).

Doesn't mean I'd not try to, if that's the only way (I kinda assumed that ouf itself brings something to have a gcd spark). oUF_gcd is simple enough for me to basically understand what's going on, but I have no idea how to diagnose the problem, since there is no lua error...

Just did a quick search for "GCD" and it revealed 3 GCD plugins for oUF. Maybe take a look at this one.

Yeah I know about that, but it's the base for hungar's gcd plugin, so I guess it suffers the same problem (it's much older, too). I'll give it a shot though

I've made my own gcd element for my personal layout, it's not very complicated to understand, it may help you so here is the code for the element:

local parent, ns = ...
local oUF = ns.oUF

local GetTime, GetSpellCooldown = GetTime, _G.GetSpellCooldown

local _, class = UnitClass('player')
local spellName
if class == 'DEATHKNIGHT' then
	spellName = GetSpellInfo(45902)
elseif class == 'DRUID' then
	spellName = GetSpellInfo(5176)
elseif class == 'HUNTER' then
	spellName = GetSpellInfo(3044)
elseif class == 'MAGE' then
	spellName = GetSpellInfo(133)
elseif class == 'PALADIN' then
	spellName = GetSpellInfo(20271)
elseif class == 'PRIEST' then
	spellName = GetSpellInfo(2061)
elseif class == 'ROGUE' then
	spellName = GetSpellInfo(1752)
elseif class == 'SHAMAN' then
	spellName = GetSpellInfo(331)
elseif class == 'WARLOCK' then
	spellName = GetSpellInfo(348)
elseif class == 'WARRIOR' then
	spellName = GetSpellInfo(772)
end

local function OnUpdate(self, elapsed)
	self.currentTime = self.currentTime + elapsed
	if self.currentTime >= self.endTime then
		self:Hide()
	end
	self.Spark:SetPoint('CENTER', self, 'LEFT', (self.currentTime - self.startTime) * self:GetWidth() / self.duration, 0)
end

local function Update(self, event)
	local gcd = self.TomGCD
	local start, duration, enable = GetSpellCooldown(spellName)
	if enable == 1 and start and duration > 0 and duration <= 1.5 then
		gcd.startTime = start
		gcd.currentTime = GetTime()
		gcd.duration = duration
		gcd.endTime = start + duration
		gcd:Show()
	else
		gcd:Hide()
	end
end

local ForceUpdate = function(element)
	return Update(element.__owner, 'ForceUpdate')
end

local function Enable(self, unit)
	local gcd = self.TomGCD
	if gcd then
		gcd.__owner = self
		gcd.ForceUpdate = ForceUpdate
		self:RegisterEvent('SPELL_UPDATE_COOLDOWN', Update)
		gcd:SetScript('OnUpdate', OnUpdate)
		gcd:Hide()
	end
end

local function Disable(self, unit)
	local gcd = self.TomGCD
	if gcd then
		self:UnregisterEvent('SPELL_UPDATE_COOLDOWN', Update)
		gcd:SetScript('OnUpdate', nil)
		gcd:Hide()
	end
end

oUF:AddElement('TomGCD', Update, Enable, Disable)

here is how I spawn it in my layout :

local function spawnGCDBar(self, width, height, ...)
	local gcd = CreateFrame('Frame', nil, UIParent)
	gcd:SetSize(width, height)
	gcd:SetBackdrop(backdrop)
	gcd:SetBackdropColor(0.25, 0.25, 0.25)

	local spark = gcd:CreateTexture(nil, 'OVERLAY')
	spark:SetTexture([[Interface\CastingBar\UI-CastingBar-Spark]])
	spark:SetBlendMode('ADD')
	spark:SetSize(20, height*2.2)
	gcd.Spark = spark

	gcd:SetPoint(...)
	return gcd
end

it should not be very complicated to adapt it to your needs

Thanks for all your help Turns out I'm simply stupid and ouf_gcd is still working. Sorry for that...
