Question

我是Java Swing的新手，我一直致力于创建一个Connect 4 Game，它通过带有gameRoom的服务器支持多人游戏。我已经解决了这个特殊的问题将近2天，并且在解决它时遇到了一些问题，例如停止使用Thread.sleep并彻底测试Game对象是否正确地传入和传出服务器。

我设计的方式是通过模型的make move命令提交每个动作。为了刷新GUI，服务器将新的Game对象发送回模型并标记控制器属性＆quot; setRepaint＆＃39;是的。然后，计时器定期检查此属性是否为true并调用repaintGrid（）方法。

经过几个小时的努力才能让它发挥作用，我无法让游戏面板重新粉刷。

可能会有所帮助的一些要点：

如果我退出应用程序并使用已经移动的Game对象重新启动它，则会绘制面板。问题在于重绘方法。
模型是静态的，每次调用Connect4App.model.getGameFromServer（）时都会更新Game属性。不确定这是否会导致问题，但如果我打印正在重新绘制为红色/蓝色的面板，我可以验证服务器在每次迭代时是否成功更新了游戏对象。

框架层次结构如下：guiMain是gamePanel的容器，它有一个gridlayout，每个都由一个GridPanel面板填充。 Grid面板基本上是Connect4 Game标记的插槽，那些是我尝试在repaintGrid方法中更新的插槽

import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JPanel;
import javax.swing.Timer;

public class GameController {

MouseAdapter me;
private JPanel gamePanel;
private boolean setRepaint = false;

/**
 * Constructor for the Game Controller. Takes in a view and a model
 * 
 * @param view
 * @param model
 */
public GameController() {
    setupGridPanels();
    setupMouseAdapter();
    Connect4App.frame.setContentPane(Connect4App.guiMain);
    Connect4App.frame.setTitle("Game View");
    goIntoTimer();

}

/**
 * Repaint Boolean used by timer. Set to true by external program
 */
public void setRepaint() {
    this.setRepaint = true;
}

/**
 * Swing Timer which checks if it needs to repaint every 8 seconds and if
 * so, calls repaintGrid
 */
private void goIntoTimer() {
    Timer timer = new Timer(50, new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            Connect4App.model.getGameFromServer();

            if (setRepaint == true) {
                repaintGrid();
                setRepaint = false;
            }

        }
    });
    timer.setRepeats(true);
    timer.setDelay(8000);
    timer.start();

}

/**
 * Sets up the Initial Game Panels in the Connect4App.guiMain panel
 */
private void setupGridPanels() {
    this.gamePanel = new JPanel();
    this.gamePanel.removeAll();

    // setting up the layout for, the game board.
    this.gamePanel.setLayout(new GridLayout(0, Connect4App.model.getGame().getGrid()[0].length));

    int numberOfRows = Connect4App.model.getGame().getGrid().length;
    int numberOfColumns = Connect4App.model.getGame().getGrid()[0].length;

    for (int r = 0; r < numberOfRows; r++) {
        for (int c = 0; c < numberOfColumns; c++) {
            Connect4App.guiMain.setCircleArc(r, c, new GridPanel(r, c));
            this.gamePanel.add(Connect4App.guiMain.getCircleArcs()[r][c]);
        }
    }
    Connect4App.guiMain.add(this.gamePanel);
}

/**
 * Sets up the mouse pressed event handleres for every panel
 */
private void setupMouseAdapter() {
    MouseAdapter mc = new MouseAdapter() {

        @Override
        public void mousePressed(MouseEvent mc) {

            GridPanel cell = (GridPanel) mc.getSource();

            // this is the column that should go in the MakeMove message
            int column = cell.getColumn();
            int row = cell.getRow();

            if (Connect4App.model.getGame().getGrid()[row][column].getState() == 0) {
                System.out.println("attempting to make move");
                Connect4App.model.makeMove(column);
            }
        }
    };

    for (int r = 0; r < Connect4App.model.getGame().getGrid().length; r++) {
        for (int c = 0; c < Connect4App.model.getGame().getGrid()[0].length; c++) {
            Connect4App.guiMain.getCircleArcs()[r][c].addMouseListener(mc);
        }
    }
}

void repaintGrid() {

    // --> This is supposed to be working
    System.out.println("repainting");

    for (int r = 0; r < Connect4App.model.getGame().getGrid().length; r++) {
        for (int c = 0; c < Connect4App.model.getGame().getGrid()[0].length; c++) {
            Connect4App.guiMain.getCircleArcs()[r][c].validate();
            Connect4App.guiMain.getCircleArcs()[r][c].repaint();
        }
    }
}
}

任何帮助将不胜感激:-D

事实证明，我在向对象输出流（游戏状态）发送同一对象时遇到问题而没有重置流，因此这导致客户端不会一直接收更新。上面的重新绘制代码正在运行。关闭线程，再次感谢。
