Tag for aura tracking with timer

Dawn · 10-25-12, 05:31 AM

I'm trying to create a tag that tracks a buff with a timer. With an Output something like "I: 29s". (Inquisition: 29seconds left)

I'm using code like this to track a buff. But how do I add a timer to it?

Code:

oUF.Tags.Methods["ProtoPWS"] = function(u) 
	if UnitAura(u, GetSpellInfo(17) or "Power Word: Shield") then return "|cffFFD800S|r" end end
oUF.Tags.Events["ProtoPWS"] = "UNIT_AURA"

I do not want to filter auras or something, should really be a tag.

I'm a little out of this stuff so bare with me, please.

I suppose it is something like this:

Code:

oUF.Tags.Methods['ITime'] = function(u) 
	local name, _,_,_,_,_, expirationTime, _ = UnitAura(u, GetSpellInfo(84963) or "Inquisition") 
    local spellTimer = GetTime()-expirationTime
	local expire = -1*(GetTime()-expirationTime)
	local timeleft = format("%.0f", expire)
	if expire > 0.5 then
		local spellTimer = "|cffffff00"..timeleft.."|r"
		return spellTimer
	end
end
oUF.Tags.Events['ITime'] = "UNIT_AURA"

but I always get an error on expirationTime:

Code:

Message: Interface\AddOns\oUF_Proto\Proto_Tags.lua:221: attempt to perform arithmetic on local 'expirationTime' (a nil value)

This seems to work error free, but it updates only every few seconds ... like 30 ... 23 ... 11 ... 7 ...

Code:

oUF.Tags.Methods['ITime'] = function(u) 
local name, _,_,_,_,_, expirationTime, _ = UnitAura(u, GetSpellInfo(84963) or "Inquisition") 
	if UnitAura(u, GetSpellInfo(84963) or "Inquisition") then		
		local spellTimer = GetTime()-expirationTime
		local expire = -1*(GetTime()-expirationTime)
		local timeleft = format("%.0f", expire)
		if expire > 0.5 then
			local spellTimer = "|cffffff00"..timeleft.."|r"
			return spellTimer
		end
	end	
end
oUF.Tags.Events['ITime'] = "UNIT_AURA"

No matter what I tried, it somehow won't update every second ... :P

Note: The "unit" I'm using this tag on is 'player', but contains no healthbar. Which means the font string is created on self, not self.Health. I suppose frequent updates don't work this way, which might be the reason for the slow update of my timer?

The tags run on their own update system. With your current code it will only update when UNIT_AURA fires. You need to set 'frequentUpdates' to true (or a threshold number) to make the tag pull updates.

Ok, that's what I was thinking, but I kinda forgot how to use 'frequentUpdates' and couldn't find how to use it, except for the obvious 'hp.frequentUpdates = true'.

tried stuff like ...
self.frequentUpdates = true (self = said player frame)
self.cpCount.frequentUpdates = true ( self.cpCount = the fontstring holding the tag)

same with values = 0.2, 0.1 ...

No effect. Maybe it's not the problem how to use it, but the code being crap.

Again sorry for being obviously confused, but it's been over a year of absence.

E: Since I'm already on it ... 'oUF.UnitlessTagEvents.UPDATE_FACTION = true' doesn't seem to work anymore, does 'oUF.Tags.SharedEvents.UPDATE_FACTION = true' work instead? Or how is this unitless tag update stuff handled, atm?

Here's an example of a tag i use for timers that i got from quse...

Eternal Flame timer.

Lua Code:

oUF.Tags.Methods['EF'] = function(u)
    local name, _,_,_,_,_, expirationTime, fromwho = UnitAura(u, GetSpellInfo(114163))
    if(fromwho == "player") then
        local spellTimer = (expirationTime-GetTime())
        local TimeLeft =  numberize(spellTimer)
        if spellTimer > 0 then
            return "|cffFFAB00"..TimeLeft.."|r"
        end
    end
end
oUF.Tags.Events['EF'] = "UNIT_AURA"

I use indicator strings.

Lua Code:

local update = .25

Lua Code:

auraStatusBR = self.Health:CreateFontString(nil, "OVERLAY")
            auraStatusBR:ClearAllPoints()
            auraStatusBR:SetPoint("BOTTOMRIGHT", 0, 7)
            auraStatusBR:SetFont(Media.font, 14, "OUTLINE")
            auraStatusBR.frequentUpdates = update
            self:Tag(auraStatusBR, oUF.Indicators["BR"])

Hope that's of any help

This helped me figuring out where to place that damn frequentupdate, thanks a lot.

Couldn't test it on my pala, yet. Servers still f***ed up, but worked with rejuvenation on a twink.

Works like a charm

Holy Power and Inquisition timer (timer turns red at <= 6sec).
