I\'m currently using an animation engine I designed that takes objects of type Drawable and adds them to a List. Drawable is an interface that has one method:

I think it would be more appropriate to override paintComponent(Graphics g) and regularly call the repaint method on the JPanel or whatever you're drawing on with a Timer. Your problems may be due to to you trying to draw and then Swing doing it's own draw.

public class Main {
public static void main(String[] args) {
    JFrame frame = new JFrame();
    JPanel panel = new JPanel() {
        public void paintComponent(Graphics g) {
            //draw here
        }
    };
    panel.setPreferredSize(800, 600);
    frame.add(panel);
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true)

    new Timer(16, new ActionListener() {
        public void actionPerformed(ActionEvent event) {
            panel.repaint();
        }
    }).start();
}
}
