一、软件运行所需要的软硬件环境

本系统是以Windows系统为操作平台，用Java编程语言来实现本系统所需功能的。本机器的配置如下：

处理器：CORE i7

主频：1.2Hz以上

内存：4G以上

硬盘：HHD 50G

编程语言：Java

开发环境：windows7

开发软件：Eclipse Mars

二、游戏流程

1.用户打开游戏，进入开始菜单。

2.用户点击开始游戏按钮，进入游戏界面；

3.用户通过触屏方式控制玩家飞机上下左右移动，躲避与子弹相撞；

4.游戏失败后，显示本次游戏得分，用的秒数和水平；

5.退出游戏

三、主要代码

1、准备代码设置窗口使用双缓冲使飞机不闪烁

Constant设置窗口大小

package com.ahut.准备代码;

publicclass Constant {

publicstaticfinalint GAME_WIDTH = 350;

publicstaticfinalint GAME_HEIGHT = 600;

}

package com.ahut.准备代码;

import java.awt.Image;

import java.awt.image.BufferedImage;

import java.io.IOException;

import https://www.360docs.net/doc/019300947.html,.URL;

public class GameUtil {

private GameUtil () {}

public static Image getImage(String path) {

BufferedImage bi = null;

try {

URL u = GameUtil.class.getClassLoader().getResource(path);

bi = javax.imageio.ImageIO.read(u);

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return bi;

}

}

package com.ahut.准备代码;

import java.awt.Frame;

import java.awt.Graphics;

import java.awt.Image;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

public class MyFrame extends Frame{

public void lauchFrame() {

setSize(Constant.GAME_WIDTH, Constant.GAME_HEIGHT);

setLocation(100, 100);

setVisible(true);

new PaintThread().start();

addWindowListener(new WindowAdapter() {

@Override

public void windowClosing(WindowEvent e) {

System.exit(0);

}

});

}

private Image offScreenImage = null;

public void update(Graphics g) {

if (offScreenImage == null)

offScreenImage = this.createImage(Constant.GAME_WIDTH, Constant.GAME_HEIGHT);

Graphics gOff = offScreenImage.getGraphics();

paint(gOff);

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

}

class PaintThread extends Thread {

public void run() {

while (true) {

repaint();

try {

Thread.sleep(40);

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}

}

}

主代码

飞机：

package com.ahut.plane;

import java.awt.Graphics;

import java.awt.event.KeyEvent;

import com.ahut.准备代码.GameUtil;

public class Plane extends GameObject {

private boolean left, up, right, down;

private boolean live = true;

public void draw(Graphics g) {

if (live) {

g.drawImage(img, (int)x, (int)y, null);

move();

}

}

public void addDirection(KeyEvent e) {

switch (e.getKeyCode()) {

case KeyEvent.VK_LEFT: //左

left = true; break;

case KeyEvent.VK_UP: //上

up = true; break;

case KeyEvent.VK_RIGHT: //右

right = true; break;

case KeyEvent.VK_DOWN: //下

down = true; break;

default: break;

}

}

public void minusDirection(KeyEvent e) {

switch (e.getKeyCode()) {

case KeyEvent.VK_LEFT: //左

left = false; break;

case KeyEvent.VK_UP: //上

up = false; break;

case KeyEvent.VK_RIGHT: //右

right = false; break;

case KeyEvent.VK_DOWN: //下

down = false; break;

default: break;

}

}

public void move() {

if (left) {

x -= speed;

}

if (right) {

x += speed;

}

if (up) {

y -= speed;

}

if (down) {

y += speed;

}

}

public Plane(String imgpath, double x, double y) { this.img = GameUtil.getImage(imgpath);

this.width = img.getWidth(null);

this.height = img.getHeight(null);

this.x = x;

this.y = y;

}

public Plane() {}

public void setLive(boolean live) {

this.live = live;

}

public boolean isLive() {

return live;

}

}

子弹：

package com.ahut.plane;

import java.awt.Color;

import java.awt.Graphics;

import java.awt.Rectangle;

import com.ahut.准备代码.Constant;

public class Bullet extends GameObject {

double degree;

public Bullet() {

degree = Math.random() * Math.PI * 2;

x = Constant.GAME_WIDTH / 2;

y = Constant.GAME_HEIGHT / 2;

width = 10;

height = 10;

}

public Rectangle getRect() {

return new Rectangle((int)x, (int)y, width, height);

}

public void draw(Graphics g) {

Color oldColor = g.getColor();

g.setColor(Color.yellow);

g.fillOval((int)x, (int)y, width, height);

x += speed * Math.cos(degree);

y += speed * Math.sin(degree);

if (y > Constant.GAME_HEIGHT - height || y < 30) {

degree = -degree;

}

if (x < 0 || x > Constant.GAME_WIDTH - width) {

degree = Math.PI - degree;

}

g.setColor(oldColor);

}

}

游戏对象：

package com.ahut.plane;

import java.awt.Image;

import java.awt.Rectangle;

public class GameObject {

Image img;

double x,y;

int speed=5;

int width,height;

public Rectangle getRect() {

return new Rectangle((int)x, (int)y, width, height);

}

public GameObject(Image img, double x, double y, int speed, int width,

int height) {

super();

this.img = img;

this.x = x;

this.y = y;

this.speed = speed;

this.width = width;

this.height = height;

}

public GameObject() {}

}

四、游戏实现截图

五、实验总结

JAVA和EclipsexMars是一款非常好的面向对象开发语言和平台，通过这一段时间的JAVA 程序开发，我感觉到尽管的是不同的语言和平台，开发程序一样需要动脑和努力，每一款软件或者游戏都不是一朝一夕能制作出的，都需要大量的构思和编程，学习好软件工程这门课对日后的编程很有用，最后还有繁琐的调试检查运行时的错误，通过这次接触JAVA我今后会更努力的学习它。
