Chat with Color

[-Red-]

Hey I was wondering how they did "/advert" in DarkRP...right now I have this:
[lua]
hook.Add( "PlayerSay", "RPcommands", function( ply, text, team )
if ( string.sub( text, 1, 7 ) == "/advert" ) then
return "[Advertisement] " .. string.sub( text, 8 )
end
[/lua]
and I was wondering how I could make this text gold...do I use the Net Library or do I use ply:sendlua?

I have already tried the networking approach...any examples of it in use....?

I did exactly that yet it did not work with string.sub...was wondering if there was another way besides that...

There isn't, and you did something wrong.
What was your code?

Where is the variable "text" defined in that code? I don't see the chat hook anywhere.

[JacobsReturn]

Is

if ( string.sub( text, 1, 7 ) == "/advert" ) then 
		return ply:PlayerMsg(Color(0,255,0), "[Advertisement]" .. string.sub( text, 8 ) )
end

wrapped in a playersay hook?
else text is not being defined...

[JasonMan]

Where's your hook?

Ninja'd :v:

It was there just did not include it...forgot an ending:P

Well the hook will never supply a nil value as an argument, so you're doing something wrong. Can you send the code in full?

[charozoid]

Here's a more efficient function to send colored text to the client:

util.AddNetworkString("chat")
function ColorMessage(...) -- ColorMessage(Color(255, 0, 0), "This is a test")
	arg = {...}
	net.Start("chat")
	net.WriteUInt(#arg, 16) --Send the number of arguments
	for _, v in pairs(arg) do
		if type(v) == "string" then --If the arg is text send a string
			net.WriteString(v)
		elseif type(v) == "table" then --If the arg is a table(color value), send RGB value(Not sending alpha)
			net.WriteUInt(v.r, 8)
			net.WriteUInt(v.g, 8)
			net.WriteUInt(v.b, 8)
		end
	end
	net.Broadcast()
end
--Clientside
net.Receive("chat", function() 
	local argc = net.ReadUInt(16) --Number of arguments
	local args = {}
		
	for i = 1, argc/2, 1 do --For every 2 arguments insert a color value and string into the chat table
		local col = Color(net.ReadUInt(8), net.ReadUInt(8), net.ReadUInt(8), 255)
		table.insert(args, col)
		table.insert(args, net.ReadString())
	end

	chat.AddText( unpack(args) )
	chat.PlaySound()
end)
