Java做一个好玩的打飞机小游戏

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

for(int i=0;i<shells.length;i++){

shells[i].draw(g);

//飞机和炮弹的碰撞检测！！！

boolean peng = shells[i].getRect().intersects(plane.getRect());

if(peng){

plane.live = false;

if(bao ==null){

bao = new Explode(plane.x, plane.y);

endTime = new Date();

period = (int)((endTime.getTime()-startTime.getTime())/1000);

}

bao.draw(g);

}

//计时功能，给出提示

if(!plane.live){

g.setColor(Color.red);

Font f = new Font(“宋体”, Font.BOLD, 50);

g.setFont(f);

g.drawString(“时间：”+period+“秒”, (int)plane.x, (int)plane.y);

}

}

g.setColor©;

}

//帮助我们反复的重画窗口！

class PaintThread extends Thread {

//@Override

public void run() {

while(true){

repaint(); //重画

try {

Thread.sleep(40); //1s=1000ms

} catch (InterruptedException e) {

e.printStackTrace();

}

}

}

}

//定义键盘监听的内部类

class KeyMonitor extends KeyAdapter {

//@Override

public void keyPressed(KeyEvent e) {

plane.addDirection(e);

}

//@Override

public void keyReleased(KeyEvent e) {

plane.minusDirection(e);

}

}

/**

• 初始化窗口

*/

public void launchFrame(){

this.setTitle(“飞机大战”);

this.setVisible(true);

this.setSize(Constant.GAME_WIDTH , Constant.GAME_HEIGHT);

this.setLocation(300, 300);

this.addWindowListener(new WindowAdapter() {

//@Override

public void windowClosing(WindowEvent e) {

System.exit(0);

}

});

new PaintThread().start(); //启动重画窗口的线程

addKeyListener(new KeyMonitor()); //给窗口增加键盘的监听

//初始化50个炮弹

for(int i=0;i<shells.length;i++){
