我试图在ContentPane中的JPanel上绘制BufferedImage

Question

所以我试图在JPanel上设置动画（连续绘制不同的png图像文件）但是如果我运行这个JPanel，则只有白屏。 我试图在JPanel上绘制BufferedImage

public void run() {
    try {
        while (true) {
            if (GAME_STATE) {
                ..................
            }       
            getContentPane().repaint();
            getContentPane().revalidate();

            Thread.sleep(GAME_SPEED);
        }
    } catch (Exception e) {
    }
}

这是run方法，它调用repaint（）和revalidate（）

public class Panel_Game extends JPanel {

    private static final long serialVersionUID = 1L;

    Panel_Game() {
        // set a preferred size for the custom panel.
        this.setPreferredSize(new Dimension(f_width, f_height + 100));
        this.setVisible(true);
        this.setLayout(null);
        this.setDoubleBuffered(true);
        this.setFocusable(true);
        this.requestFocus(true);
    }

    @Override
    public void paint(Graphics g) {
        buffImage = createImage(f_width, f_height + 100);
        buffg = buffImage.getGraphics();
        getContentPane().revalidate();

        super.paintComponent(g);

        Draw_Background();
        Draw_Player();
        Draw_Weapon();
        Draw_Enemy();
        Draw_EnemyWeapon();
        Draw_Item();
        .............
        g.drawImage(buffImage, 0, 0, this);
    }
}

这是我尝试在

上绘制图像的类

public void Game_InterFace() { 
    JLabel Label_Menu_Board = new JLabel();
    JLabel Label_AP_Board = new JLabel();
    JLabel Label_Save_Board = new JLabel();
    JLabel Label_Load_Board = new JLabel();

    Panel_Game panel_Game = new Panel_Game();
    panel_Game.addKeyListener(this);
    .............................................
            .............................................           
    panel_Game.add(btn_Menu);
    panel_Game.add(btn_AP);
    panel_Game.add(label_Status);

    getContentPane().add(panel_Game);
    getContentPane().repaint();
}

.......

public Game_main() {
    start();

    setLocation(0, 0);
    setUndecorated(true);
    setSize(f_width, f_height);
    setResizable(false);
    setVisible(true);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    Container contentPane = getContentPane();
    contentPane.setLayout(null);

    Game_Home();
}
