1.项目整体构造

2.主类代码展示

public class MyGameFrame extends Frame {

Image planeImg = GameUtil.getImage(“images/plane.png”);

Image bg = GameUtil.getImage(“images/bg.jpg”);

Plane plane = new Plane(planeImg,250,250);

Shell[] shells = new Shell[50];

Explode bao ;

Date startTime = new Date();

Date endTime;

int period; //游戏持续的时间

//@Override

public void paint(Graphics g) { //自动被调用。 g相当于一只画笔

Color c = g.getColor();

g.drawImage(bg, 0, 0, null);

plane.drawSelf(g); //画飞机

//画出所有的炮弹
