Question

如何从服务器向客户端发送对象（“播放器”）的坐标？

服务器：

package it.unical.igpe.online;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class Server {
    static ServerSocket serverSocket;
    static DataOutputStream dos;
    static DataInputStream dis;
    private static boolean accepted;

    public static void initializeServer() {
        try {
            serverSocket = new ServerSocket(7777);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void listenForServerRequest() {
        Socket socket = null;
        try {
            socket = serverSocket.accept();
            dos = new DataOutputStream(socket.getOutputStream());
            dis = new DataInputStream(socket.getInputStream());
            accepted = true;
            System.out.println("CLIENT HAS REQUESTED TO JOIN, AND WE HAVE ACCEPTED");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

连接方法：

private boolean connect() {
    try {
        socket = new Socket(ip, port);
        dos = new DataOutputStream(socket.getOutputStream());
        dis = new DataInputStream(socket.getInputStream());
        accepted = true;
    } catch (IOException e) {
        System.out.println("Unable to connect to the address: " + ip + ":" + port + " | Starting a server");
        return false;
    }
    System.out.println("Successfully connected to the server.");
    clientConnected = true;
    return true;
}

运行：

@Override
public void run() {
    if(!accepted) {
        Server.listenForServerRequest();
    }
    gameManager.startGame();
    while(!gameManager.gameOver()) {
        this.requestFocusInWindow();
        try {
            Thread.sleep(40);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        if

        gameManager.update();
        handleActions();
        this.repaint();
    }
}

我想在run方法中发送播放器（World.getPlayer1().getX() ecc..）的坐标，并更新世界的每个动作。因此，客户端和服务器可以看到另一个玩家的位置。我应该将DataInputStream和DataOutputStream与writeInt（）和readInt（）一起使用吗？

在服务器和客户端（Java）之间发送坐标
