Java - 如何使用SwingWorker创建多线程游戏

Question

我想用Threads创建一个[1 Player vs PC]游戏.

我们的主板上有10*10两种颜色的形状,如下所示:

当玩家点击蓝色圆圈时,他们的颜色变成灰色.

在另一侧PC应该将所有RED矩形变为灰色.

WINNER是谁先清除他/她自己的形状.

播放器的代码工作正常但是,我的问题在于实现游戏的PC端,正如我在本文中所读到的,我应该使用SwingWorker在GUI中实现线程.这是我第一次使用SwingWorkers,我不知道它应该如何正常工作.

这是我的代码:

主类

public class BubblePopGame {

public static final Color DEFAULT_COLOR1 = Color.BLUE;
public static final Color DEFAULT_COLOR2 = Color.RED;

public BubblePopGame() {
    List<ShapeItem> shapes = new ArrayList<ShapeItem>();

    int Total = 10;
    for (int i = 1; i <= Total; i++) {
        for (int j = 1; j <= Total; j++) {
            if ((i + j) % 2 == 0) {

                shapes.add(new ShapeItem(new Ellipse2D.Double(i * 25, j * 25, 20, 20),
                        DEFAULT_COLOR1));
            } else {
                shapes.add(new ShapeItem(new Rectangle2D.Double(i * 25, j * 25, 20, 20),
                        DEFAULT_COLOR2));
            }
        }
    }

    JFrame frame = new JFrame("Bubble Pop Quest!!");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    ShapesPanel panel = new ShapesPanel(shapes);
    frame.add(panel);
    frame.setLocationByPlatform(true);
    frame.pack();
    frame.setVisible(true);
}

public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            new BubblePopGame();
        }
    });
}

}

形状项类

public class ShapeItem {

private Shape shape;
private Color color;

public ShapeItem(Shape shape, Color color) {
    super();
    this.shape = shape;
    this.color = color;
}

public Shape getShape() {
    return shape;
}

public void setShape(Shape shape) {
    this.shape = shape;
}

public Color getColor() {
    return color;
}

public void setColor(Color color) {
    this.color = color;
}

}

ShapesPanel类

public class ShapesPanel extends JPanel {

private List<ShapeItem> shapes;
private Random rand = new Random();
private SwingWorker<Boolean, Integer> worker;

public ShapesPanel(List<ShapeItem> shapesList) {
    this.shapes = shapesList;
    worker = new SwingWorker<Boolean, Integer>() {            

        @Override
        protected Boolean doInBackground() throws Exception {
            while (true) {
                Thread.sleep(200);
                int dim = rand.nextInt(300);
                publish(dim);                
                return true;
           }
        }

        @Override
        protected void done() {
            Boolean Status;
            try {                    
                Status = get();
                System.out.println(Status);
                super.done();                    //To change body of generated methods, choose Tools | Templates.
            } catch (InterruptedException ex) {
                Logger.getLogger(ShapesPanel.class.getName()).log(Level.SEVERE, null, ex);
            } catch (ExecutionException ex) {
                Logger.getLogger(ShapesPanel.class.getName()).log(Level.SEVERE, null, ex);
            }
        }

        @Override
        protected void process(List<Integer> chunks) {
            int mostRecentValue = chunks.get(chunks.size()-1);
            System.out.println(mostRecentValue);
                Color color2 = Color.LIGHT_GRAY;
                ShapeItem tmpShape = shapes.get(mostRecentValue);
                if(tmpShape.getColor()==Color.RED){
                    tmpShape.setColor(color2);
                }
                repaint();                
       }

    };
    worker.execute ();

    addMouseListener(new MouseAdapter() {
        @Override
        public void mouseClicked(MouseEvent e) {
            Color color1 = Color.LIGHT_GRAY;
            for (ShapeItem item : shapes) {
                if (item.getColor() == Color.BLUE) {
                    if (item.getShape().contains(e.getPoint())) {
                        item.setColor(color1);
                    }
                }
            }
            repaint();
        }
    });
}

@Override
protected void paintComponent(Graphics g) {
    super.paintComponent(g);

    Graphics2D g2 = (Graphics2D) g.create();

    for (ShapeItem item : shapes) {
        g2.setColor(item.getColor());
        g2.fill(item.getShape());
    }

    g2.dispose();
}

@Override
public Dimension getPreferredSize() {
    return new Dimension(300, 300);
}

private Color getRandomColor() {
    return new Color(rand.nextFloat(), rand.nextFloat(),
            rand.nextFloat());
}

}

如果我正确理解你的代码，你正在制作一个游戏，人类玩家必须尽可能快地点击他的所有形状，而电脑也随机点击形状。第一个清除所有形状的人获胜。

如果这是正确的，您可能需要调整您SwingWorker的

• 循环直到游戏结束。return目前，由于该语句，您的循环在第一次到达循环末尾时退出
• 由于您没有对 的布尔返回值执行任何操作SwingWorker，因此您不妨让它返回 void
• 无需调用get该done方法。当该方法被调用时，该方法SwingWorker就完成了。您似乎只对中间结果感兴趣
• 在该process方法中，您可能想要循环所有值。请注意，该process方法不会在您每次执行操作时调用publish。process当 EDT（事件调度线程）可用时，您发布的值将被分组并批量传递给方法
