我想创建一个[1个玩家对电脑]的游戏,并使用线程。
我们在棋盘上有一个10*10的两种颜色形状,如下所示:
当玩家点击蓝色圆圈时,它们的颜色变成灰色。
在另一侧,PC应该将所有红色矩形都变成灰色。
赢家是谁先把自己的形状全部清除掉。
玩家的代码很好用,但是,实现电脑端的游戏时出现了问题。正如我在这篇文章中所读到的那样,在GUI中实现线程应该使用SwingWorker。这是我第一次使用SwingWorkers,不知道如何才能正常工作。
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();
}
});
}
}
形状项目类
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());
}
}
