《JAVA程序开发课程设计》项目设计项目名称：TankWar 软件专业：软件工程班级：13软工1班姓名：毛晨光学号：1322120124一、需求分析：基本功能：1.玩家控制的坦克能够四处移动并且打击敌方坦克；2.敌方坦克能够随机四处移动并且打击玩家控制的坦克；3.玩家控制的坦克拥有血量，而敌方坦克没有；4.坦克受到攻击时血条会缩短；5.敌方坦克被消灭完之后，提示游戏胜利；6.用户方坦克被消灭后提示游戏结束；特色功能：1.坦克具有图片，不单单只是个圈圈。

2.增加了血包功能，地图上会随机出现一个血包，我方坦克开过会增加血量。

二、系统设计：1.TankMap类：实现游戏界面地图的初始化。

2.PainTread类：绘制和重绘功能。

3.DirectionHandler:监听用户的键盘输入。

4.Tank类：实现坦克的初始化，绘制，移动，发射等功能。

5.EnemyTank：实现敌方坦克的初始化，绘制，移动，发射等功能。

6.Shell类：实现炮弹的初始化，绘制，移动，攻击功能。

7.Explor类：实现爆炸的初始化。

绘制功能，爆炸效果由绘制半径从小到大再到小的圆实现。

8.Direction类：包含枚举。

9.Blood类：用于实现血包的功能。

三、功能实现。

一．绘制地图功能：public class TankMap extends Frame{//定义地图的尺寸。

public static final int MAPWIDTH=800;public static final int MAPHEIGHT=600;//我方坦克Tank t=null;//定义随机出现的血包Random r=new Random();Image bufferImage=null;public static java.util.List<Shell>shells=new

20, 60);gbuffer.fillRect(65,55,t.getLife(),5);gbuffer.setColor(c);paint(gbuffer);g.drawImage(bufferImage, 0, 0, null);}//内部类，主要通过调用repaint方法，实现绘图功能class PaintThread implements Runnable{@Overridepublic
