Casters Classcolor.

Hey fellow Wowiers!

Im currently tracking buffs and debuffs on my raidframes, i would like to try and have my bufficons border colored by the class it is cast from, if that makes sense.

Currently the part of the code looks like this were i color the border..

Lua Code:

local buffcolor = { r = 1.0, g = 1.0, b = 0 }
local updateBuff = function(icon, texture, count, dtype, duration, expires, buff)
local color = buffcolor
icon.border:SetBackdropBorderColor(color.r, color.g, color.b,1)

Tried a couple things but getting errors and my lua knowledge is very limited..have a feeling i need to get this to work with the color function somehow?

Lua Code:

local _, class = UnitClass(unit)
local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]

Im probably really off here and it makes me feel really dumb :P.. so if anyone could point me in the right direction i'd be thankful!

EDIT: If you need more code to be able to help out let me know! thank you.

You want sth like this.

Lua Code:

--functions
 
  local postUpdateDebuff = function(element, unit, button, index, offset)
 
    local name, rank, icon, count, dispelType, duration, expires, caster, isStealable, shouldConsolidate, spellID, canApplyAura, isBossDebuff, value1, value2, value3 = UnitAura(unit, index, "HARMFUL")
    if not name then return end
    local _, class = UnitClass(caster)
    if not class then return end  
    local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]
    if not color then return end
    --print(color)
    button.border:SetBackdropBorderColor(color.r, color.g, color.b,1)
 
  end
 
  local postUpdateBuff = function(element, unit, button, index, offset)
 
    local name, rank, icon, count, dispelType, duration, expires, caster, isStealable, shouldConsolidate, spellID, canApplyAura, isBossDebuff, value1, value2, value3 = UnitAura(unit, index, "HELPFUL")
    if not name then return end
    local _, class = UnitClass(caster)
    if not class then return end  
    local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]
    if not color then return end
    --print(color)
    button.border:SetBackdropBorderColor(color.r, color.g, color.b,1)
 
  end  
 
  local postUpdateAura = function(element, unit, button, index, offset)
 
    local name, rank, icon, count, dispelType, duration, expires, caster, isStealable, shouldConsolidate, spellID, canApplyAura, isBossDebuff, value1, value2, value3 = UnitAura(unit, index)
    if not name then return end
    local _, class = UnitClass(caster)
    if not class then return end  
    local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]
    if not color then return end
    --print(color)
    button.border:SetBackdropBorderColor(color.r, color.g, color.b,1)
 
  end  
 
  --post update aura icon 
 
  --self.Buffs.PostUpdateIcon = postUpdateBuff
  --self.Debuffs.PostUpdateIcon = postUpdateDebuff
  self.Auras.PostUpdateIcon = postUpdateAura

Which function you need to call depends on how you created your aura icons. If you used self.Buffs you use postUdateBuff ... etc.

Regarding UnitAura check: http://wowprogramming.com/docs/api/UnitAura
For the oUF documentation on auras read: https://github.com/haste/oUF/wiki/element---auras

I'm currently not sure. It may actually be possible to work with CreateAura instead of PostUpdateIcon because you can extract the unit from element:GetParent().unit.

That would look like this for Auras:

Lua Code:

--function
  local createIcon = function(element, index)
 
    local unit = element:GetParent().unit
    if not unit then return end
    local name, rank, icon, count, dispelType, duration, expires, caster, isStealable, shouldConsolidate, spellID, canApplyAura, isBossDebuff, value1, value2, value3 = UnitAura(unit, index)
    if not name then return end
    local _, class = UnitClass(caster)
    if not class then return end  
    local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]
    if not color then return end
    --print(color)
    button.border:SetBackdropBorderColor(color.r, color.g, color.b,1)
 
  end  
 
  self.Auras.CreateIcon = createIcon

The benefit is that CreateIcon is only used once. But I'm not sure if it is sufficient (means if it is called each time a new aura is created, even if an aura existed already for the same index)

Thanks for the elaborate answer Zork, i really appreciate it!

I'll play around with it and see if i can get it working! :)

If it's of any help to easier get this working in my current code, i use oUF_Mlight's way to track auras.. which is based of oUF_Freebgrid.

Thanks again! :)

You have to use PostUpdate as CreateIcon won't update the border color.

You could use the same code as proposed by Zork for Buffs/Debuffs/Auras like that:

Code:

local postUpdateAura = function(element, unit, button, index, offset)

 

    local name, _, _, _, _, _, _, caster = UnitAura(unit, index, button.filter)

    if not name then return end

    local _, class = UnitClass(caster)

    if not class then return end  

    local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]

    if not color then return end

    --print(color)

    button.border:SetBackdropBorderColor(color.r, color.g, color.b,1)

 

end

The other possibility is to use CustomFilter, because your icon.border is not icon.overlay. CustomFilter gets the results from UnitAura passed as local arguments, so you don't need to call it one more time in PostUpdate.

Thanks for the info guys!

What confuses me the most is the structure i have i guess...

I can get this to work with my buffs/debuffs that i use for all my UF's but raidframes because i use a different structure there with spellID's and stuff.

Now i have a file called auras (this is debuffs on my raidframes) and a file called auras2 (these are buffs on my raidframes).

I spawn them in my core layout with

Lua Code:

local auras = CreateFrame("Frame", nil, self.Health)
auras:SetSize(22,22)
auras:SetPoint("CENTER", self.Health,0,6)
auras.size = 21
self.freebAuras = auras
self.freebAuras.PostUpdateIcon = postUpdateAura

Most of the confusion is if i add the postupdate function in my core or in my aura files?

I tried both, im not getting any errors, but the frames are just not being colored(white).

Thanks for being awesome.

I only overflew the code for oUF_Mlight. What you linked in your post is apparently some custom aura element for tank buffs. There is another one for raid debuffs I suppose and the standard oUF auras element in core.lua. I suppose you don't need to change the first two and only want the alter the behavior of the default aura element.

In that case you'll want to change PostUpdateIcon like that:

Code:

local PostUpdateIcon = function(icons, unit, icon, index, offset)

        local name, _, _, _, _, duration, expirationTime, caster, _, _, SpellID = UnitAura(unit, index, icon.filter)



        if icon.isPlayer or UnitIsFriend("player", unit) or not icon.isDebuff or oUF_MlightDB.AuraFilterwhitelist[tostring(SpellID)] then

                icon.icon:SetDesaturated(false)

                if duration and duration > 0 then

                        icon.remaining:Show()

                else

                        icon.remaining:Hide()

                end

                icon.count:Show()

                

                local _, class = UnitClass(caster)

                if class then

                        local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]

                        if color then

                                icon.bd:SetBackdropBorderColor(color.r, color.g, color.b,1)

                        end

                end

        else

                icon.icon:SetDesaturated(true) -- grey other's debuff casted on enemy.

                icon.overlay:Hide()

                icon.remaining:Hide()

                icon.count:Hide()

        end



        if duration then

                icon.bd:Show() -- if the aura is not a gap icon show it"s bd

        end



        icon.expires = expirationTime

        icon:SetScript("OnUpdate", CreateAuraTimer)

end

I haven't tested this and I don't know if it plays well with all the conditions for desaturation and hiding the backdrop.

It doesn't matter where the actual function is defined, as long as postUpdateAura is a valid reference to the function when this line of code executes:

Code:

self.freebAuras.PostUpdateIcon = postUpdateAura

Based on your description of the problem, it sounds like postUpdateAura is nil when that line runs, so you're not actually setting a PostUpdateIcon member on the element.

Thanks, im getting somewhere thanks to all your great help! :)

It is kind of working now but i am unfortunately getting errors when trying lfr, haven't had time
to test it more... but i've had a full lfr with no error aswell.

Mostly i can say that when entering Gara'jals spiritrealm i always got errors.

This is how i added it

Lua Code:

local show = CustomFilter(auras, unit, icon, name, rank, texture, count, dtype, duration, expires, caster, spellID)
        if(show) and icon.buff then
        local _, class = UnitClass(caster)
        if class then
            local color = (CUSTOM_CLASS_COLORS or RAID_CLASS_COLORS)[class]
            if color then
                icon.border:SetBackdropBorderColor(color.r, color.g, color.b,1)
            end
        end

The error is pointing at

Lua Code:

local _, class = UnitClass(caster)

and also this part in oUF\events.lua

Lua Code:

eventFrame:SetScript('OnEvent', function(_, event, arg1, ...)
        local listeners = registry[event]
        if arg1 and not sharedUnitEvents[event] then
            local frames = framesForUnit[arg1]
            if frames then
                for frame in next, frames do
                    if listeners[frame] and frame:IsVisible() then
                        frame[event](frame, event, arg1, ...)
                    end
                end
            end
        else
            for frame in next, listeners do
                if frame:IsVisible() then
                    frame[event](frame, event, arg1, ...)
                end
            end
        end
    end)

Any hints on what the cause might be, because that error doesn't tell me that much im afraid :(

What is the actual error message?

oh, how how can i forget to mention that im sorry :o

Lua Code:

Locals: Message: Interface\AddOns\oUF_NIN\elements\auras2.lua:155: Usage: UnitClass("unit")
Time: 11/22/12 09:43:14
Count: 4
Stack: [C]: ?
[C]: in function `UnitClass'
Interface\AddOns\oUF_NIN\elements\auras2.lua:155: in function `func'
Interface\AddOns\oUF\events.lua:113: in function `?'
Interface\AddOns\oUF\events.lua:69: in function <Interface\AddOns\oUF\events.lua:62>

caster can be nil if the aura wasn't applied by a unit, or if the unit that applied it does not currently have a valid unit token. Just add a check to make sure caster is non-nil before proceeding with the class lookup.
