I want to create a game [1 Player vs PC] with streams.
We have 10 * 10 two colors in our board:
when a player clicks on BLUE Circles, their color turns gray.
on the other hand, the PC should turn all the RED Rectangles into gray.
A WINNER is one who Cleans all his own forms earlier.
The code for the player works fine, but, My problem is to implement the PC-side of the game, as I read in this article , I have to use SwingWorker to implement Threading in the GUI. This is my first time using SwingWorkers, and I don’t know how this should work correctly.
Here are my codes:
Main class
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(); } }); }
}
Form element class
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; }
}
Class ShapesPanel
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()); }
}
