动画椭圆形朝着Java中的另一个椭圆形移动

Question

我正在创建一个Java游戏，其中有一个球（球员）和其他球应该到达这个球员（敌人等）。玩家可以使用箭头键移动来逃脱这些敌人。我计算了数学，以便在玩家移动后找到敌人的新X和Y位置，但我无法找到一种方法来平滑地动画这些动作。我尝试使用线程，但它没有正常工作，所以我删除了一些代码。还有一种方法可以在游戏开始时在新位置和/或不同时间创建新敌人，但我无法让计时器工作。这是迄今为止该程序的代码。

import java.awt.Canvas;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.image.BufferStrategy;
import java.awt.event.*;
import javax.swing.*;

public class game implements Runnable {

    JFrame frame;
    int myX = 400;
    int myY = 400;

    //x and y of second oval
    int X2 = 200;
    int Y2 = 200;


    Canvas canvas;
    BufferStrategy bufferStrategy;
    boolean running = true;

    public game() {
        frame = new JFrame("Basic Game");
        JPanel panel = (JPanel) frame.getContentPane();
        panel.setPreferredSize(new Dimension(500, 500));
        panel.setLayout(null);
        canvas = new Canvas();
        canvas.setBounds(0, 0, 500, 500);
        canvas.setIgnoreRepaint(true);
        panel.add(canvas);
        canvas.addKeyListener(new KeyAdapter() {
            @Override
            public void keyPressed(KeyEvent evt) {
                moveIt(evt);
            }
        });
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setResizable(false);
        frame.setVisible(true);
        canvas.createBufferStrategy(2);
        bufferStrategy = canvas.getBufferStrategy();
        canvas.requestFocus();
    }
    public void run() {
        while (running = true) {
            Paint();
            try {
                Thread.sleep(25);
            } catch (InterruptedException e) {
            }
        }
    }
    public static void main(String[] args) {
        game ex = new game();
        new Thread(ex).start();
    }
    public void Paint() {
        Graphics2D g = (Graphics2D) bufferStrategy.getDrawGraphics();
        g.clearRect(0, 0, 500, 500);
        Paint(g);
        bufferStrategy.show();

    }

    protected void Paint(Graphics2D g) {
        //paints the two ovals
        g.fillOval(myX, myY, 30, 30);
        g.fillOval(X2,Y2, 30, 30);
    }

    public void moveIt(KeyEvent evt) {
     switch (evt.getKeyCode()) {
    //calculates positions for second oval
            case KeyEvent.VK_DOWN:
                myY += 10;
                X2 = (int) ((X2 + myX) * 0.5);
                Y2 = (int) ((Y2 + myY) * 0.5);
                break;
            case KeyEvent.VK_UP:
                myY -= 10;
                X2 = (int) ((X2 + myX) * 0.5);
                Y2 = (int) ((Y2 + myY) * 0.5);
                break;
            case KeyEvent.VK_LEFT:
                myX -= 10;
                X2 = (int) ((X2 + myX) * 0.5);
                Y2 = (int) ((Y2 + myY) * 0.5);
                break;
            case KeyEvent.VK_RIGHT:
                myX += 10;
                X2 = (int) ((X2 + myX) * 0.5);
                Y2 = (int) ((Y2 + myY) * 0.5);

                break;
        } 
    }
}

我将非常感谢能够通过球和动画的动画获得任何帮助。
