对于一个学校计算机项目，我决定用 Java 制作一个吃豆人风格的游戏（和另外两个人）。我们都没有太多经验，所以到目前为止，我们基本上一直在自学。我们已经取得了相当大的进步，但在这一点上我们似乎已经停滞不前。
当胖子碾过糖果时，我们怎样才能让糖果消失呢？我们已经尝试使用重绘，但我们似乎无法让事情正常工作。
（我还有其他需要帮助的事情，但它们的问题不同）
谢谢您的帮助！
到目前为止，这是我们的代码：
迷宫类：
package Fatman;
import javax.swing.*;
public class Maze {
public static void main(String[] args){
new Maze();
}
public Maze(){
JFrame f = new JFrame();
f.setTitle("Fatman!");
f.add(new Board());
f.setSize(816, 838);
f.setLocationRelativeTo(null);
f.setVisible(true);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
