Hi,

I am working with the net libraries in processing and I am wondering if there is anyway of having a server communicate a message directly to one connected client instead of broadcasting to all connected clients via the write() function.

This is the code for my server:

Code:

import processing.net.*;

////  VARIABLES  ////

//  CREATE SERVER  //
Server server;

String incomingMessage = "";

////  SETUP  ////

void setup ()  {
  size(400, 200);
  
  //  INITALIZE PUBLIC VARIABLES  //
  
  //  SERVER  //
  server = new Server(this, 6262);
}

////  DRAW  ////

void draw ()  {
  background(255);
  
  check4Client();
}

////  FUNCTIONS  ////
  
  void serverEvent (Server server, Client client)  {
     incomingMessage = "A new client has connected: " + client.ip();
  }
  
  void check4Client ()  {
    //  set client
    Client client = server.available();
    //  Check if null
    if (client != null)  {
	//  Recieve message
	incomingMessage = client.readStringUntil('*');
	println("Client says: " + incomingMessage);
	server.write(incomingMessage);
    }
  }
//End of Sketch 

The server reads the string from a specified client:

  Client client = server.available();

but when The server sends a response I use the Write function which sends a return string to all clients.  This is annoying for many reasons.  clients receive strings of irrelevant information which slows down their sketch and strings can contain sensitive information.

Any help would be appreciated.

Thanks in advance

It's not a bug; it's a feature.
