How to send a string from the server to a specific client?

[CoopaTroopa]

Thanks to code_gs I have the !timeleft command sorted, but I don't yet have the answer for any other form of message from the server to the player (e.g. gamemode messages being sent as a notification instead of a chat message).

To clarify, what I'm looking to do is have a function which can be used to put a string in chat (ex: player just killed you!), which can then be sent to a specific player and then to have the client show that as a notification ala the undo notification. So far I have this, and I see no reason as to why it isn't working. Come on facepunch, make me feel real sad about my skill (or lack of) in lua.

Clientside:

net.Receive("Notification", function( len,ply )
	notification.AddLegacy( str, NOTIFY_GENERIC, 1 )
	surface.PlaySound( "buttons/button15.wav" )
end )

Serverside:

function Notify( str )
	net.Start( "Notification" )
	net.WriteString( string "str" )
	net.Send( Entity(1) )
end

function msg.Send( ply, str )

	ply:Notify(str)

end

Your code doesn't really make any sense. Firstly, there's no need to create special global functions for this sort of thing -- you can just embed the code in the primary function. You also should be using hooks instead of overriding GAMEMODE functions. Also, if you are supporting three different command strings, you can just use a table lookup for comparrisons. Lastly, using an OnPlayerChat hook will prevent any networking from having to be done since it's all clientside.

Try this:

local timeleft = {
	["timeleft"] = true,
	["!timeleft"] = true,
	["/timeleft"] = true
}

hook.Add( "OnPlayerChat", "CoopaTroopa-Notification", function( ply, text )
	if ( timeleft[text:lower()] ) then
		-- Only print if the local client said it, but always block it
		if ( ply == LocalPlayer() ) then
			notification.AddLegacy( string.ToMinutesSeconds(GetTimeLeft()).." left of current round, "..GetRoundsLeft().." remaining rounds.", NOTIFY_GENERIC, 1 )
			surface.PlaySound( "buttons/button15.wav" )
		end
		
		return ""
	end
end )

To be honest, I was originally planning to have it so I could send other strings, as a form of replacement for the server putting stuff into chat, which is part of the reason it looks so incredibly poor.

That being said, thanks a lot, that makes a lot more sense than what i was doing

Sorry, but I'm going to bump instead of starting another thread. Should be alright, according to the rules.

why are you bumping it if someone already gave you an answer?

I would've said the same thing by the way - it's much simpler and doesn't send unnecessary net messages

They've given a solution to an issue, but they haven't answered the question. I'm still glad he answered, but I still don't know how to make a server send a specific string to a specific player.

I think your original code would work but it needs a few changes:

// CLIENTSIDE
// This code works with both serverside examples
net.Receive( 'Notification', function( len, ply )
	local str = net.ReadString()
	notification.AddLegacy( str, NOTIFY_GENERIC, 1 )
	surface.PlaySound( "buttons/button15.wav" )
end )

// SERVERSIDE
util.AddNetworkString( 'Notification' )

local msg = {}

msg.Send = function( ply, str )
	net.Start( 'Notification' )
	net.WriteString( str )
	net.Send( ply )
end

// USAGE EXAMPLE:
// local ply = Entity(1)
// msg.Send( ply, "TEST STRING" )

But please use the way that other guy posted before, it's much simpler and doesn't do pointless networking

And if you want to add the 'Notify' function (or any other function) to the player metatable you have to use [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/Global/FindMetaTable]FindMetaTable[/url], e.g.

// SERVERSIDE
util.AddNetworkString( 'Notification' )

local meta = FindMetaTable( "Player" )

function meta:Notify( str )
	net.Start( 'Notification' )
	net.WriteString( str )
	net.Send( self )
end

// USAGE EXAMPLE:
// local ply = Entity(1)
// ply:Notify( "TEST STRING" )

But there's no reason to make it so unnecessarily complicated when you can just use one hook
