This example gets the joined client's name and sends him a welcome message including his name. 

-- we register greetPlayer as a handler for the event

end
addEventHandler("onPlayerJoin", root, onPlayerJoin)

function onPlayerChat(playerMessage, messageType)
	local normalMessage = messageType == 0

	if not normalMessage then
		return false -- If it's not normal type message, cancel code execution
	end

	local playerName = getPlayerName(source) -- Get player name
	local playerColors = chatColors[source] -- Get player stored colors
	local colorR, colorG, colorB = playerColors[1], playerColors[2], playerColors[3] -- Store them into different variables

	outputChatBox(playerName..": #E0D0B0"..playerMessage, root, colorR, colorG, colorB, true) -- Output our message
	cancelEvent()
end
addEventHandler("onPlayerChat", root, onPlayerChat)
