這篇文章給大家分享的是有關Java如何實現接月餅小游戲的內容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。
設計游戲界面，用swing實現
設計背景
設計得分物體-月餅，碰到加一分
設計障礙物-月亮，碰到會死亡
監聽鼠標的左右鍵，用來控制籃子左右移動
設計積分系統
將resource文件夾設為resource（Project Manage中可以設置），因為要用里面的圖片
游戲開始界面：
public class Start {
public static void main(String[] args) throws URISyntaxException {
new EatGame();
}
}public class EatGame extends JFrame implements ActionListener, MouseListener
{
private final int WIDTH = 400;
private final int HEIGHT = 800;
private int score;
private int ticks;
private boolean gameOver = false;
private GameControl control;
private List<Moon> moons;
private List<Cake> cakes;
private Timer timer;
private ChangeE changeE;
/**

*/
public EatGame() throws URISyntaxException {
