在java中读取和写入连接（套接字）

我正在做一个2d多人游戏。我使用套接字制作了一些简单的应用程序，例如聊天室。现在我正试图将它应用到我的游戏中，但没有取得多大成功。也许我不理解循环或者读写不正确？如果调用read函数，读卡器是否等待数据？ 我想做的是：两个玩家可以看到对方的位置（并在那里画一个黑色正方形）。我得到的：另一个玩家在屏幕上随机跳跃。（但至少已创建连接） 我试着这样做： 客户端（不是整个代码，只是不确定的部分和连接）：

服务器：

public class ServerBase {
    ServerSocket serverSocket;
    ArrayList clients;  //for the client writers
    private int id = 1;

    class ClientHandler implements Runnable {   //Every client gets a thread
        private Socket soc;
        private DataInputStream reader;
        private DataOutputStream writer;
        private int x;
        private int y;
        private int id;

        public ClientHandler(Socket s, DataOutputStream wr) {
            soc = s;
            writer = wr;
            try {
                reader = new DataInputStream(soc.getInputStream());
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        public void run() {
            try {
                while(true) {   //Maybe this is wrong too, I'm jut unsure of this
                    id = reader.readInt();  //get the id (first thing that player sends)
                    x = reader.readInt();  //same with x and y
                    y = reader.readInt();
                    sendEveryone(id, x, y);  //send everyone the player datas
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        public void sendEveryone(int a, int b, int c) {
            Iterator it = clients.iterator();
            while(it.hasNext()){
                try {
                    DataOutputStream writer = (DataOutputStream) it.next();
                    writer.writeInt(a);
                    writer.writeInt(b);
                    writer.writeInt(c);
                    writer.flush();
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            }
        }
    }

    public void init() {
        clients = new ArrayList();

        try {
            serverSocket = new ServerSocket(5099);

            while(true) {
                Socket clientSocket = serverSocket.accept();  //wait for a client
                System.out.println("got one");
                DataOutputStream clientWriter = new DataOutputStream(clientSocket.getOutputStream());
                clients.add(clientWriter);  
                clientWriter.writeInt(id);
                id++;

                Thread t = new Thread(new ClientHandler(clientSocket, clientWriter));  //make the thread for the client
                t.start();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        new ServerBase().init();
    }
}

有人能解释一下我应该怎么做？还有没有一种更有效的方式来发送数据（在一块中？）。怎么做？

看看我在生产中使用的

java.util.rmi

，它与套接字完全纠结在一起。在

中，（true）

是否每次都创建一个t线程？它只存在于while范围内？如果调用read函数，读卡器是否等待数据？对阅读积木。不，它基本上永远存在。每个客户都有一条线索。@Elliott Frisch很有用，谢谢。
