Need help with RP names.

[BolONYz]

Hey guys, I need help with rp names for my gamemode. I want an rp name system like DarkRP, where you can change the name and it'll be over your head so people can see. I have the names hovering over heads but it shows only their steam username. I've tried alot of things, none seem to work but I am a beginner. Help would be much appreciated

I've made a menu to change their rp name. Here's the code that changes their name.

		local DermaButton = vgui.Create( "DButton" )
			DermaButton:SetParent( f ) // Set parent to our "DermaPanel"
			DermaButton:SetText( "Submit!" )
			DermaButton:SetPos( 25, 300 )
			DermaButton:SetSize( 150, 50 )
			DermaButton.DoClick = function ()
			
				local NameString = GetGlobalString( "BN" .. LocalPlayer():SteamID() .. "" )
				
				SetGlobalString( "BN" .. LocalPlayer():SteamID() .. "" , DermaText:GetValue() )
				
				print( "You changed your name to " .. GetGlobalString( "BN" .. LocalPlayer():SteamID() .. "" ) )
				
			end

And the code that show their rp names over their heads.

function HoveringNames()

	for _, target in pairs(player.GetAll()) do
		if target:Alive() and target != LocalPlayer() then
		
			local targetPos = target:GetPos() + Vector(0,0,84)
			local targetDistance = math.floor((LocalPlayer():GetPos():Distance( targetPos ))/40)
			local targetScreenpos = targetPos:ToScreen()
			
			if targetDistance < 7 then
			draw.SimpleText(target:Nick(), "Trebuchet18", tonumber(targetScreenpos.x), tonumber(targetScreenpos.y), Color(200,25,25,200), TEXT_ALIGN_CENTER)
			end 
			
		end
	end
end
hook.Add("HUDPaint", "HoveringNames", HoveringNames)

1. You are using ply:Nick() in the draw hook, which obviously returns their steamusername, so you want to access the GlobalString you created there.

draw.SimpleText(GetGlobalString("BN" .. target:SteamID(), target:Nick()), "Trebuchet18", tonumber(targetScreenpos.x), tonumber(targetScreenpos.y), Color(200,25,25,200), TEXT_ALIGN_CENTER)

2. If SetGlobalString is being run on the client, it only changes the variable for that client. In order to make it work you should use a net message to the server and change it there.

Clientside code:

local DermaButton = vgui.Create( "DButton" )
			DermaButton:SetParent( f ) // Set parent to our "DermaPanel"
			DermaButton:SetText( "Submit!" )
			DermaButton:SetPos( 25, 300 )
			DermaButton:SetSize( 150, 50 )
			DermaButton.DoClick = function ()
				local NameString = GetGlobalString( "BN" .. LocalPlayer():SteamID() .. "" )
				net.Start("change_rp_name")
				net.WriteString(DermaText:GetValue())
				net.SendToServer()
				print( "You changed your name to " .. DermaText:GetValue() .. "" ) )
			end

Serverside code:

...
util.AddNetworkedString("change_rp_name")
net.Receive("change_rp_name", function(len, ply)
SetGlobalString( "BN" .. ply:SteamID(), net.ReadString() )
end)
...

Please note:
That code is extremely bad but it will work, you can start from there and put some checks in place on the serverside. If you are planning on using a database to store the rp name don't forget to escape the string.
Also please don't use SetGlobalString, if really necessary you might want to use [URL="http://wiki.garrysmod.com/page/Entity/SetNetworkedString"]ply:SetNetworkedString(key, str)[/URL] or [URL="http://wiki.garrysmod.com/page/Entity/SetDTString"]ply:SetDTString(index, str)[/URL]
