I spent the last few hours building an automatic server. It makes having shared objects between Client/Server very simple. It also uses reflection to detect changed variables and then sends the updates to everyone else that is connected.

It has some holes as of now, but I thought it was a very interesting idea.
It’s not very secure so I wouldn’t recommend using it for a real server. But if you need to test a server/client quickly, this can easily facilitate that.

All Objects that are to be shared between the server/clients extend the SharedObject class. Then you call the init class and then you no longer have to worry about sending updates of the variables to the server/clients. It’s done automatically for you.


public class Player extends SharedObject {

	private static final long serialVersionUID = 1L;

	public int Health = 20;
	public int Stamina = 10;
	public int Level = 1;

	public Player(String name) {
		this.identity = name;
		this.registerKeys("Health", "Stamina", "Level");
	}

}



public class MyGame implements Runnable {

	private ConnectionToServer server;

	private Player player;

	public MyGame() {
		try {
			System.out.println("Attempting to connect to server.");
			Socket socket = new Socket("localhost", 2240);
			server = new ConnectionToServer(socket);
			System.out.println("Connected to server.");

			String name = JOptionPane.showInputDialog("What's your name?");
			player = new Player(name);
			player.init(server);
		} catch(Exception e) {
			System.out.println("Failed to connect to server.");
		}
	}
}

After calling the registerKeys on Field names, and calling the init(PacketCommunicator) function on a shared object, it’s all taken care of for you.

To get it running, just import it into eclipse, and then run 2 applications: 1) MyAutoServer 2) MyGame

Comments would be much appreciated! :slight_smile:
