如何添加更多以不同速度移动的图像

Question

我试图使一个程序，将工作和功能像简单的赛马，但我不能设置不同的速度。就我所见，当计时器取不同的值时，例如：我有两张照片，一张有40个计时器，另一张有80个计时器，它们以相同的速度移动，但一张有80个计时器的照片会变短，或者更少的时钟，而这张有40个计时器的照片会变得更平滑。

public class AnimatedThing {

   public AnimatedThing() {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                }

                JFrame frame = new JFrame("Trke");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setPreferredSize(new Dimension(400, 600));
                frame.setLayout(new BorderLayout());
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);

                frame.setLayout(new GridLayout(4, 1));
                frame.setBackground(Color.white);

                enemyRed enemyPink = new enemyPink(); // sub-panel 1
                frame.add(enemyPink);
                frame.setLocationRelativeTo(null);
            }
        });
    }
     public class enemyPink extends JPanel {

        private BufferedImage enemyPink;
        public enemyPink() {
            try {
                enemyPink = ImageIO.read(new File("C:\\Users\\SMRTNIK\\Documents\\NetBeansProjects\\Sistem elektronske biblioteke - SEB\\images\\enemy - pink.png"));
                Timer timer2 = new Timer(20, new ActionListener() {

                    @Override
                    public void actionPerformed(ActionEvent e) {
                        xPos += direction;
                        if (xPos + enemyPink.getWidth() > getWidth()) {
                        } else {
                            repaint();
                        }
                    }

                });
                timer2.setRepeats(true);
                timer2.setCoalesce(true);
                timer2.start();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }

        @Override
        public Dimension getPreferredSize() {
            return enemyPink == null ? super.getPreferredSize() : new Dimension(enemyPink.getWidth() * 4, enemyPink.getHeight());
        }

        @Override
        protected void paintComponent(Graphics g) {
            super.paintComponent(g);
            g.drawImage(enemyPink, xPos, 0, this);
        }

    }

最好先阅读一下标准文档，然后看看如何做到这一点的教程。代码很混乱，我解不出来。我将发布一个链接:https://youtu.be/kmgo00avvew
