对于学校的计算机项目，我决定用Java创建一个吃豆人风格的游戏（和另外两个人一起）。我们都没有太多的经验，所以我们基本上都在自我教育。我们取得了相当大的进步，但我们现在似乎已经停滞不前了。
当Fatman跑过来时，我们怎么能让糖果消失？我们尝试过使用重绘，但似乎无法使事情正常运行。
（我还有其他需要帮助的事情，但他们有不同的问题）
感谢您的帮助！
到目前为止，这是我们的代码：
迷宫课程：
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);
}
}

有什么想法吗？

然而。你可以做什么，将糖果位置设置在屏幕外（例如：candy.x = -100;）
虽然说你的游戏循环在哪里？
public void startGame（）{
} public void stopGame（）{
} public void update（）{//强制图形和用户输入更新 游戏状态}
还考虑去www.java-gaming.org他们有很棒的教程来帮助你。

Player.move()中没有任何东西在吃点。您必须更新变量Map.Map[]的值以跟踪它应该表示的内容。否则，这段代码只是空单词/符号，它们一次只能从程序员那里做一条指令，但不会使用编程语言的强大功能让计算机根据它遇到的条件工作。
