DefNet. User counter

Hello there! I want to ask a relatively simple question: how do I find out how many people are currently connected to a local server in DefNet? And also how to send some s-to-c messages without a c-to-s message before that?

You can add a new function to the server to return the length of the client table:

britzl/defnet/blob/master/defnet/tcp_server.lua#L66

    
      
          	assert(port, "You must provide a port")
          	assert(on_data, "You must provide an on_data function")
          
          
	log("Creating TCP server")
          	
          	local server = {}
          
          
	local co = nil
          	local server_socket = nil
          
          
	local clients = {}
          	local queues = {}
          
          
	local function remove_client(connection_to_remove)
          		for i,connection in pairs(clients) do
          			if connection == connection_to_remove then
          				table.remove(clients, i)
          				queues[connection_to_remove] = nil
          				if on_client_disconnected then
          					local client_ip, client_port = connection:getpeername()
          					on_client_disconnected(client_ip, client_port, connection)
