(ExtremelyNeedHelp) Please help to Turn TCP server in to UDP (really short code)

[Lionlev]

Hi, I've made a little mistake on making the server for my game, I've made a TCP instead of UDP...
But UDP code is quite different and not sure how to start a thread class when client connects..
So here is the code:

import java.io.IOException;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
public class Connector 
{
	public static ArrayList<Socket> ConnectionArray = new ArrayList<Socket>();
	public static ArrayList<String> CurrentUsers = new ArrayList<String>();
	public static int ConnectionTimeOut = 5000;
	public static PrintWriter OUT;
	public static void main(String[] args) throws IOException
	{
		try
		{
			
			final int PORT = 2807;
			ServerSocket SERVER = new ServerSocket(PORT);
			System.out.println("Server launched.");
			while(true)
			{
				Socket SOCK = SERVER.accept();
				ConnectionArray.add(SOCK);
				OUT =  new PrintWriter(SOCK.getOutputStream());
				OUT.println("Connected to the server. \n");
				OUT.flush();
				System.out.println("Someone connected.");
				
				ChatServer CHAT = new ChatServer(SOCK);
				Thread X = new Thread(CHAT);
				X.start();
			}
		}
		catch(Exception X) {System.out.print(X);}
	}
}

When posting a topic to multiple forums one should indicate which other forums one has posted to so that readers will not waste time answering a query that has been answered in another forum.

Sorry. Please ignore me ! I thought I had seen the same post on another forum but, since I can't find it any more and the link I posted came back here, it seems I was mistaken.

lol it's ok
Good luck! By the way, you got any experience on "Datapackets" in java?

I use TCP rather than UDP so probably can't help. There are many books on Java network programming that you can download; just Google for "Java UDP network programming". OK, you probably won't get the code handed to you on a plate but you will learn much more by researching and coding it yourself.

Yeah but just a problem is that I've made a rpg side scroller and the TCP server and it works, I can see the clients, clients can see my char but when everyone are walking so much slower than the usual speed because clients getting each movement and the client even didn't process some yet, the coordinates are still collecting there and collecting.. Probably UPD client will get only the latest coordinates but lol the problem is that I have no idea how to start a new thread from it
Like Socket SOCK = server.accept(); so I can use the SOCK to start the thread, I can't seem to find something like Socket in the Datapacket..
