How to use JLayered Pane to display an image on to

问题:

We are working on a pacman game and we want to add a picture of pacman on top of the background. If someone could provide some example code of implementing the Jlayered Pane that would be great.

Here is some of the code we attempted to write. When we try to run it, nothing displays:

  JLayeredPane pacman = new JLayeredPane();  

  pacman.setPreferredSize(new Dimension(576, 655));





  ImageIcon sprite = new ImageIcon("C:\\\\Users\\\\16ayoubc\\\\Desktop\\\\Pacman-moving.gif");  
  ImageIcon background = new ImageIcon("C:\\\\Users\\\\16ayoubc\\\\Desktop\\\\background.png");  

  JLabel pacmansprite = new JLabel(sprite);
  JLabel background1 = new JLabel(background);

  background1.setVisible(true);
  pacman.setLocation(255, 255);
  pacman.setVisible(true);
  pacman.setOpaque(true);

  pacman.add(background1, new Integer(0));

I think that you should just add a canvas to the JLayeredPane, and than paint the image using java2D (found in java.awt.Graphics, and java.awt.Graphics2D. More info on this is available.). than, try using the Graphics2D method drawImage(BufferedImage img, int x, int y, int width, int hight);. This may be complicated, but it might work better.

I hope this works!
