Chat Bubble help

[cokedrivers]

Hello,

I have found a code I'm trying to get to my liking and need some assistance.

Below is the current code i'm using I have everything set how I would like it except the Senders name, I can get the "player" names to be class color but I cannot seem to get the NPC's name to change to the reaction they have against me (ie Friendly hated and so on).

Current Code:

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',
}
 
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
        else
            region:Hide()
        end
    end
 
    frame.text:SetFontObject('SystemFont_Small')
    frame.text:SetJustifyH('LEFT')
 
    frame:ClearAllPoints()
    frame:SetPoint('TOPLEFT', frame.text, -7, 25)
    frame:SetPoint('BOTTOMRIGHT', frame.text, 7, -7)
    frame:SetBackdrop({
        bgFile = 'Interface\\Tooltips\\UI-Tooltip-Background',
        edgeFile = 'Interface\\Tooltips\\UI-Tooltip-Border',
        tileSize = 16,
        edgeSize = 12,
        insets = {left=3, right=3, top=3, bottom=3},
    })
    frame:SetBackdropColor(0, 0, 0, 1)
    local _, class = UnitClass("player")
    local color = RAID_CLASS_COLORS[class] or { r = 0.5, g = 0.5, b = 0.5 }
    frame:SetBackdropBorderColor(color.r * 255, color.g * 255, color.b * 255)
 
    frame.sender = frame:CreateFontString(nil, 'OVERLAY', 'NumberFont_Outline_Med')
    frame.sender:SetPoint('BOTTOMLEFT', frame.text, 'TOPLEFT', 0, 4)
    frame.sender:SetJustifyH('LEFT')
 
    frame:HookScript('OnHide', function()
        frame.inUse = false
    end)
end
 
local function UpdateFrame(frame, guid, name)
    if (not frame.text) then
        SkinFrame(frame)
    end
    frame.inUse = true
 
    local class
    if (guid ~= nil and guid ~= '') then
        _, class, _, _, _, _ = GetPlayerInfoByGUID(guid)
    end
    
    if (name) then
        local color = RAID_CLASS_COLORS[class] or { r = 0.75, g = 0.75, b = 0.75 }
        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
 
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 ChatBubbleFrame = CreateFrame('Frame')
for event, cvar in pairs(events) do
    ChatBubbleFrame:RegisterEvent(event)
end
 
ChatBubbleFrame:SetScript('OnEvent', function(self, event, msg, sender, _, _, _, _, _, _, _, _, _, guid)
    if (GetCVarBool(events[event])) then
        ChatBubbleFrame.elapsed = 0
        ChatBubbleFrame:SetScript('OnUpdate', function(self, elapsed)
            self.elapsed = self.elapsed + elapsed
            local frame = FindFrame(msg)
            if (frame or self.elapsed > 0.3) then
                ChatBubbleFrame:SetScript('OnUpdate', nil)
                if (frame) then
                    UpdateFrame(frame, guid, sender)
                end
            end
        end)
    end
end)

I have tried:

local reaction = UnitReaction(unit, 'player')
 
        if (reaction) then
            r = FACTION_BAR_COLORS[reaction].r
            g = FACTION_BAR_COLORS[reaction].g
            b = FACTION_BAR_COLORS[reaction].b
        else

But I keep getting an error that says unit is nil.

Any help on this would be great.

Thanks Coke
