Chat Commands lua simple help?

[jacobcooper18]

hook.Add( "OnPlayerChat", "pointrange", function( ply, text, team )

    if (string.sub(text, 1, 11) == "/pointrange") then
	    ply:PrintMessage( HUD_PRINTTALK, "1st Point:" )
		return true
	end
	
end)

I have been coding for a while now, and everytime I try too make something new with something involving ply or player meta data it says: attempt to concatenate a userdata value!
I used too always make commands, and use them too printmessage? but wtf, its not working anymore?

Like WTF, is facepunch removing lua code? because I want too type /pointrange and get sent a message telling me: 1st point:

Are you running it client side?

OnPlayerChat is a client hook. Won't work on the server.

Just do this. To hell with string.sub()

if txt == "/pointrange" then
         //do shit
end

Can you show me that, inside of a hook so I know what im doing..

[Nick78111]

You can put it in lua/autorun/client on your server and it should work.

[jacobcooper18]

hook.Add( "OnPlayerChat", "pointrange", function( ply, text, team )

    if (string.sub(text, 1, 4) == "/ptr") then
	    PrintMessage( HUD_PRINTTALK, "1st Point:" .. ply:NearestPoint( GetClosestPoint[1] ) )
		return true
	end
	
end)

[ERROR] lua/autorun/client/debug.lua:141: attempt to concatenate a userdata value

I just tested

hook.Add( "OnPlayerChat", "pointrange", function( ply, text, team )

    if text == "/pointrange" then
	    ply:PrintMessage( HUD_PRINTTALK, "1st Point:" )
		return true
	end
	
end)

and it works with no errors...

[Thane17]

hook.Add("OnPlayerChat", "PointRange", function (ply, txt, team)
     if txt = "/pointrange" then 
          ply:PrintMessage(HUD_PRINTTALK, "1st Point:" .. ply:NearestPoint(GetClosestPoint[1])) return true

     end
end)

untested so idk. And are you sure that the error has to do with the snippet you gave us?

ninja'd

Just read the error and it has to do with

ply:NearestPoint(GetClosestPoint[1]))

You're trying to put userdata into a string.. Doesn't work.
