Help with Name Colors

Hello,

What I want to do is in the chat bubbles have the units name color match their reaction to me.

Ive tried for the past 2 hours with everything I try it pops up a error.

Here is the code I'm currently using:
Code:
local function UpdateFrame(frame, guid, name)
	if not frame.text then SkinFrame(frame) end
	frame.inUse = true
	
	if settings.showSender then
		local class
		if guid ~= nil and guid ~= "" then
			_, class, _, _, _, _ = GetPlayerInfoByGUID(guid)
		end
		
		if name then
			local color = RAID_CLASS_COLORS[class] or {  r = 1, g = 1, b = 1 }
			frame.sender:SetText(("|cFF%2x%2x%2x%s|r"):format(color.r * 255, color.g * 255, color.b * 255, name))
			if frame.text:GetWidth() < frame.sender:GetWidth() then
				frame.text:SetWidth(frame.sender:GetWidth())
			end
		end
	end
end
But every thing the is a NPC or my Followers show up white text. I would like the to use my custom colors like this that is my Tooltip addon.

Tooltip Custom Colors:
Code:
CUSTOM_FACTION_BAR_COLORS = {
    [1] = {r = 1, g = 0, b = 0},
    [2] = {r = 1, g = 0, b = 0},
    [3] = {r = 1, g = 1, b = 0},
    [4] = {r = 1, g = 1, b = 0},
    [5] = {r = 0, g = 1, b = 0},
    [6] = {r = 0, g = 1, b = 0},
    [7] = {r = 0, g = 1, b = 0},
    [8] = {r = 0, g = 1, b = 0},
}

function GameTooltip_UnitColor(unit)

    local r, g, b

    if (UnitIsDead(unit) or UnitIsGhost(unit) or UnitIsTapDenied(unit)) then
        r = 0.5
        g = 0.5
        b = 0.5
    elseif (UnitIsPlayer(unit)) then
        if (UnitIsFriend(unit, 'player')) then
            local _, class = UnitClass(unit)
            if ( class ) then
                r = RAID_CLASS_COLORS[class].r
                g = RAID_CLASS_COLORS[class].g
                b = RAID_CLASS_COLORS[class].b
            else
                r = 0.60
                g = 0.60
                b = 0.60
            end
        elseif (not UnitIsFriend(unit, 'player')) then
            r = 1
            g = 0
            b = 0
        end
    elseif (UnitPlayerControlled(unit)) then
        if (UnitCanAttack(unit, 'player')) then
            if (not UnitCanAttack('player', unit)) then
                r = 157/255
                g = 197/255
                b = 255/255
            else
                r = 1
                g = 0
                b = 0
            end
        elseif (UnitCanAttack('player', unit)) then
            r = 1
            g = 1
            b = 0
        elseif (UnitIsPVP(unit)) then
            r = 0
            g = 1
            b = 0
        else
            r = 157/255
            g = 197/255
            b = 255/255
        end
    else
        local reaction = UnitReaction(unit, 'player')

        if (reaction) then
            r = CUSTOM_FACTION_BAR_COLORS[reaction].r
            g = CUSTOM_FACTION_BAR_COLORS[reaction].g
            b = CUSTOM_FACTION_BAR_COLORS[reaction].b
        else
            r = 157/255
            g = 197/255
            b = 255/255
        end
    end

    return r, g, b
end
Ive tried addin the tolltip colors to the chat buble lua and the did this line:

Code:
local color = RAID_CLASS_COLORS[class] or {  r = GameTooltip_UnitColor(unit).r, g = GameTooltip_UnitColor(unit).g, b = GameTooltip_UnitColor(unit).b }
but it give me an error thet there is no unit.

I'm not the greatest at coding but I most of the time can fumble my way threw.

Any help would be great.
Thanks
Coke

You need a UnitID to be able to get reaction colors. I'm guessing since you're using GUID that this is coming from a chat event, which can come from things without valid UnitIDs.

Thanks for the reply.

Here is the whole code I'm trying to use. As I said before I'm not a great code writer.

Code:
------------------------------------------------------------------------
--	 Chat Bubbles
------------------------------------------------------------------------

local settings = {
	fontSender = {"Fonts\\FRIZQT__.TTF", 12},
	showSender = true,
}

-- Events & corresponding cVars
local events = {
	CHAT_MSG_SAY = "chatBubbles", CHAT_MSG_YELL = "chatBubbles",
	CHAT_MSG_PARTY = "chatBubblesParty", CHAT_MSG_PARTY_LEADER = "chatBubblesParty",
	CHAT_MSG_MONSTER_SAY = "chatBubbles", CHAT_MSG_MONSTER_YELL = "chatBubbles", CHAT_MSG_MONSTER_PARTY = "chatBubblesParty",
}

-- WorldFrame frames are always uiScaled it seems
local function FixedScale(len)
	return GetScreenHeight() * len / 768
end

local function RotateCoordPair(x, y, ox, oy, a, asp)
	y = y / asp
	oy = oy / asp
	return ox + (x - ox) * math.cos(a) - (y - oy) * math.sin(a),
		(oy + (y - oy) * math.cos(a) + (x - ox) * math.sin(a)) * asp
end

-- Clip + rotate texture
local function SetRotatedTexCoords(tex, left, right, top, bottom, width, height, angle, originx, originy)
	local ratio, angle, originx, originy = width / height, math.rad(angle), originx or 0.5, originy or 1
	local LRx, LRy = RotateCoordPair(left, top, originx, originy, angle, ratio)
	local LLx, LLy = RotateCoordPair(left, bottom, originx, originy, angle, ratio)
	local ULx, ULy = RotateCoordPair(right, top, originx, originy, angle, ratio)
	local URx, URy = RotateCoordPair(right, bottom, originx, originy, angle, ratio)
	tex:SetTexCoord(LRx, LRy, LLx, LLy, ULx, ULy, URx, URy)
end

-- Skin a new frame
local function SkinFrame(frame)
	for i = 1, select("#", frame:GetRegions()) do
		local region = select(i, frame:GetRegions())
		if region:GetObjectType() == "FontString" then
			frame.text = region
		end
	end
	
	-- Chat text
    frame.text:SetFontObject('SystemFont_Small')
    frame.text:SetJustifyH('LEFT')
	
	-- Sender text
	if settings.showSender then
		frame.sender = frame:CreateFontString(nil, 'OVERLAY', 'NumberFont_Outline_Med')
		frame.sender:SetPoint('BOTTOMLEFT', frame.text, 'TOPLEFT', 0, 4)
		frame.sender:SetJustifyH('LEFT')
	end
	
	-- Border
	frame:ClearAllPoints()
	frame:SetPoint("TOPLEFT", frame.text, -7, settings.showSender and 10 + FixedScale(settings.fontSender[2]) or 7)
	frame:SetPoint("BOTTOMRIGHT", frame.text, 7, -7)
    frame:SetBackdrop({
        bgFile = 'Interface\\Tooltips\\UI-Tooltip-Background',
        edgeFile = 'Interface\\Tooltips\\UI-Tooltip-Border',
		tile = true,
        tileSize = 16,
        edgeSize = 12,
        insets = {left=3, right=3, top=3, bottom=3},
    })
    frame:SetBackdropColor(0, 0, 0, 1)
	
	
	-- Hide Chat Bubble Tail
	local bottom, tail
	for i = 1, select("#", frame:GetRegions()) do
		local region = select(i, frame:GetRegions())
		if region:GetObjectType() == "Texture" then
			if ({region:GetPoint()})[1] == "BOTTOMLEFT" and region:GetPoint(2) then
				bottom = region
			elseif region:GetTexture() == "Interface\\Tooltips\\ChatBubble-Tail" then
				tail = region
			end
		end
	end
	
	tail:ClearAllPoints()
	tail:Hide()
	
	frame:HookScript("OnHide", function() frame.inUse = false end)
end

-- Update a frame
local function UpdateFrame(frame, guid, name)
	if not frame.text then SkinFrame(frame) end
	frame.inUse = true
	
	if settings.showSender then
		local class
		if guid ~= nil and guid ~= "" then
			_, class, _, _, _, _ = GetPlayerInfoByGUID(guid)
		end
		
		if name then
			local color = RAID_CLASS_COLORS[class] or {  r = 157/255, g = 197/255, b = 255/255 }
			frame.sender:SetText(("|cFF%2x%2x%2x%s|r"):format(color.r * 255, color.g * 255, color.b * 255, name))
			if frame.text:GetWidth() < frame.sender:GetWidth() then
				frame.text:SetWidth(frame.sender:GetWidth())
			end
		end
	end
end

-- Find chat bubble with given message
local function FindFrame(msg)
	for i = 1, WorldFrame:GetNumChildren() do
		local frame = select(i, WorldFrame:GetChildren())
		if not frame:GetName() and not frame.inUse then
			for i = 1, select("#", frame:GetRegions()) do
				local region = select(i, frame:GetRegions())
				if region:GetObjectType() == "FontString" and region:GetText() == msg then
					return frame
				end
			end

		end
	end
end

local f = CreateFrame("Frame")
for event, cvar in pairs(events) do f:RegisterEvent(event) end

f:SetScript("OnEvent", function(self, event, msg, sender, _, _, _, _, _, _, _, _, _, guid)
	if GetCVarBool(events[event]) then
		f.elapsed = 0
		f:SetScript("OnUpdate", function(self, elapsed)
			self.elapsed = self.elapsed + elapsed
			local frame = FindFrame(msg)
			if frame or self.elapsed > 0.3 then
				f:SetScript("OnUpdate", nil)
				if frame then UpdateFrame(frame, guid, sender) end
			end
		end)
	end
end)
Thanks again for any help with this.

Ok so I was able to get the chat bubble to be skinned the way I like it but unfortunately I was not able to get the sender working.

Also it is diabled in raids and instances so no error pops up when in them,

Code:
Code:
------------------------------------------------------------------------
--	 Skin the Chat Bubbles
------------------------------------------------------------------------
local select, pairs = select, pairs
local format = string.format
local CreateFrame = CreateFrame
local C_ChatBubbles_GetAllChatBubbles = C_ChatBubbles.GetAllChatBubbles

local function StyleBubble(frame)
	for i=1, frame:GetNumRegions() do
		local region = select(i, frame:GetRegions())
		if region:GetObjectType() == "Texture" then
			region:SetTexture(nil)
		elseif region:GetObjectType() == "FontString" then
			frame.text = region
		end
	end
	
	frame.text:SetFontObject('SystemFont_Small')
	frame.text:SetJustifyH('LEFT')

	frame:ClearAllPoints()
	frame:SetPoint('TOPLEFT', frame.text, -7, 7)
	frame:SetPoint('BOTTOMRIGHT', frame.text, 7, -7)
	frame:SetBackdrop({
		bgFile = 'Interface\\Tooltips\\UI-Tooltip-Background',
		edgeFile = 'Interface\\Tooltips\\UI-Tooltip-Border',
		tile = true,
		tileSize = 16,
		edgeSize = 12,
		insets = {left=3, right=3, top=3, bottom=3},
	})
	frame:SetBackdropColor(0, 0, 0, 1)
	
	local r, g, b = frame.text:GetTextColor()
	frame:SetBackdropBorderColor(r, g, b, .8)
			
	frame.isSkinned = true
end

local frame = CreateFrame('Frame')
frame.lastupdate = -2 -- wait 2 seconds before hooking frames
local numChildren = 0
frame:SetScript('OnUpdate', function(self, elapsed, guid, name)
	self.lastupdate = self.lastupdate + elapsed
	if (self.lastupdate < .1) then return end
	self.lastupdate = 0	
	
	for _, chatBubble in pairs(C_ChatBubbles_GetAllChatBubbles()) do
		if not chatBubble.isSkinned then				
			StyleBubble(chatBubble)
		end
	end
end)
Hope this helps someone.
