用java制作小游戏：小恐龙跑酷

插入链接与图片

运行图片:（第一次做游戏，画风比较丑哈！最左边的就是主角小恐龙了，中间的是障碍物仙人掌，右边的小狗也是障碍物，右上角的是分数条）

以下是Java工程中的每一个类的代码：

MainFrame.java类：

	Container c = getContentPane();
	c.add(p);
	
	addKeyListener(p);
}

public static void main(String[] args) {
	MainFrame frame = new MainFrame();
	frame.setBounds(500, 235, 1020, 780);//设置窗体的大小和位置
	frame.setVisible(true);
}

public void restart() {
	Container c=getContentPane();
