Two lua files. Neither work.

[Charrax]

So I have two files. colours.lua (the u is on purpose) and roundsong.lua

Both use the hooks but neither work.

Colours is in autorun. Roundsong is in autorun/server.

RoundSong

resource.AddFile("sound/ttt/tators.wav")
resource.AddFile("sound/ttt/roundstart.mp3")

local function PlayMusic(wintype)
   if wintype == WIN_INNOCENT then
      BroadcastLua('surface.PlaySound("ttt/thump01e.mp3")')
   else
      BroadcastLua('surface.PlaySound("ttt/tators.wav")')
   end
end
hook.Add("TTTEndRound", "PlayMusic", PlayMusic)

local function PlayStartMusic()
if GetRoundState() == ROUND_BEGIN then
	BroadcastLua('surface.PlaySound("ttt/roundstart.mp3")')
end
hook.Add("TTTBeginRound", "PlayStartMusic", PlayStartMusic)

Colours

if SERVER then
   AddCSLuaFile("colours.lua")
else

   function OwnerColors(ply)
	if ply:SteamID() == "STEAM_0:0:9310913" then -- Charrax
		return Color( 5, 181, 225 )
	end
end
 
hook.Add( "TTTScoreboardColorForPlayer ", "OwnerColors", ColorName )

end

[Mr. Gash]

if SERVER then
   AddCSLuaFile("colours.lua")
else
   function OwnerColors(ply)
		if ply:SteamID() == "STEAM_0:0:9310913" then -- Charrax
			return Color( 5, 181, 225 )
		end
	end
 	hook.Add( "TTTScoreboardColorForPlayer", "OwnerColors", OwnerColors )
end

As for the music, are you getting any errors? (And you don't need to check the round state in the TTTBeginHook, it won't be getting called at any other time.) Try putting the sound files in somewhere other than /ttt/.

Nvm working :D

I removed the "if GetRoundState() == ROUND_BEGIN then"
