Filter on nameplates debuffs.

Hello there !

I'm a long time user of the Blizzard nameplates and i know this can be done by just getting Plater or whatever.

I'm currently working on a small addon who will allow me to show all my debuffs over the ennemy nameplates. Today, with the help of Tomcat (twitch.tv/TomCat), he explained me a lot about it and deep dived for me in the nameplates features.

Right now, the code is looking like this :

Lua Code:

local function UpdateBuffs(self, unit, filter, showAll)
    if (not showAll) then
        self:UpdateBuffs(unit, filter, true)
    end
end
 
local updateFrame = CreateFrame("FRAME")
 
local tracker = { }
 
local minDelay = 1.0
local totalElapsed = 0
 
local function OnUpdate(self, elapsed)
    totalElapsed = totalElapsed + elapsed
    if (totalElapsed > minDelay) then
        totalElapsed = 0
        for i = 1, 20 do
            if (not tracker[i]) then
                local nameplate = _G["NamePlate" .. i]
                if (nameplate and nameplate.UnitFrame and nameplate.UnitFrame.BuffFrame) then
                    tracker[i] = true
                    hooksecurefunc(nameplate.UnitFrame.BuffFrame, "UpdateBuffs", UpdateBuffs)
                end
            end
        end
    end
end
 
updateFrame:SetScript("OnUpdate", OnUpdate)

What is does : showing all the debuffs over the nameplates, including your friends warrior debuffs for example.

What i want in the final : showing all my debuffs and only mine, and if it includes also my pet mortal wounds, better but i guess, harder to do.

For this problem, i found many ask how to do that, some solutions who seems to not work nowadays like :

https://www.mmo-champion.com/threads...-BuffContainer

Here are 2 solutions, the first one isnt working and my understanding in lua is not enough to fix it on my own. And the second one who is a whitelisting but removing everything else and also, doesn't work with some things like Sinful Revelation.

The goal is to show like a concussive shots like a debuff over the nameplates. This will help many PvPer who dont wanna jump in a full nameplates addon.

If you have any suggestions, any time to help me, i will be super grateful.

I don't see a way to do it without taint but this didn't throw any errors the little I tested at a training dummy:

Lua Code:

local GetNamePlateForUnit = C_NamePlate.GetNamePlateForUnit
local OriginalUpdateBuffs = NameplateBuffContainerMixin.UpdateBuffs
 
local alteredNamePlates = { }
 
local function ShouldShowBuff(frame, name, caster)
    return name -- already filtered
end
 
local function UpdateBuffs(self, unit, filter, showAll)
    OriginalUpdateBuffs(self, unit, "HARMFUL|PLAYER")
end
 
local frame = CreateFrame("Frame")
 
frame:SetScript("OnEvent", function(self, event, unit)
    local nameplate = GetNamePlateForUnit(unit)
    if nameplate and not alteredNamePlates[nameplate] then
        alteredNamePlates[nameplate] = true
        local buffFrame = nameplate.UnitFrame.BuffFrame
        buffFrame.ShouldShowBuff = ShouldShowBuff
        buffFrame.UpdateBuffs = UpdateBuffs
    end
end)
 
frame:RegisterEvent("NAME_PLATE_UNIT_ADDED")

I'm a little bit scared of what the addon will eat as memory. Will try this out this evening.

Thank you so much for providing assistance !

you can hooksecurefunc "UpdateBuffs" but it will update the buffs two times; your solution is better I guess. Not sure you need to hook "ShouldShowBuff".

Less resource consumption would be probably no addon.

I use this. It hides all debuffs and just shows the debuffs you add into the whitelist.

Lua Code:

--Filter Buffs and Debuffs on Nameplates (including Personal Resource Display)
 
local whitelist = {
    --Priest Debuffs
    ["Shadow Word: Pain"] = "player",
    ["Mind Soothe"] = "all",
}
 
--This function is for name filtering
local function newShouldShowBuff(_,name,caster)
    return name and caster and (whitelist[name] == caster or whitelist[name] == "all")
end
 
local function Mixin(baseFrame)
    baseFrame.UnitFrame.BuffFrame.ShouldShowBuff = newShouldShowBuff
end
 
local f = CreateFrame("Frame")
    f:RegisterEvent("NAME_PLATE_UNIT_ADDED")
    f:SetScript("OnEvent", function(_,_,unitId)
    
    Mixin(C_NamePlate.GetNamePlateForUnit(unitId))
end)
 
for _,baseFrame in pairs(C_NamePlate.GetNamePlates()) do
    Mixin(baseFrame)
end
