一、系统需求、主要功能称述

1.系统需求

用户可在主界面进行注册、登录、查看排行榜;登录成功后,可选择ShootGame(飞机大战游戏)或CarGame(道路狂飙游戏)。

2.主要功能

  1. 竞技排行榜:用户查看排行榜实现与他人争榜竞技。
  2. 用户注册与登录:用户可以根据既定规则注册与登录专属账号,体验专属的游戏记录。
  3. ShootGame:随增加增加生成敌机与小蜜蜂数量、给定时器设置进度、飞行物的生成/入场/走步/射击方法/碰撞方法、游戏结束、绘制游戏状态(开始/进行/暂停/结束)、绘制飞行物(小蜜蜂/小敌机/Boss机/英雄机)、绘制分数(Score/MaxScore/Life/Energy)、绘制背景
  4. 用户注册与登录:用户可以根据既定规则注册与登录专属账号,体验专属的游戏记录。
  5. 项目打包:将项目打包成可执行文件,实现项目移植,摆脱jdk,IJ等环境约束。
  6. 云端存储:用户信息存储于云服务器端,不额外占用用户内存,杜绝直接的信息修改,实现所有用户信息同步。

二、系统体系结构、设计方案(类图)

1.系统体系结构

- GUI设计逻辑

- ShootGame 设计逻辑

2. 设计方案(类图)

2.1 package Flyings:
该包以Flying的飞行类为父类,分Shoot,Collision接口,Flying中定义飞行物的固有特性,以及飞行物的共有方法,Hero,Boss,Bee,Enemy,Bullet为Flying的子类,继承Flying中的变量和方法,提高了代码的复用性,也提高了代码的鲁棒性。

2.2 package User:
User包中包含User类与存放配置文件位置的Info接口,User类主要包含用户与后端数据库连接、登录、注册和保存等方法。

2.3 Run类:
包含项目主界面,用户登录注册和游戏入口的图形界面。

三、系统实现技术、编码说明

1.系统实现技术

1.1 JDBC连接数据库:实现账号密码验证、注册,和用户信息的检索、插入、更新、删除等操作,统一对数据进行管理,保证了数据的安全性和完整性。
1.2 exe文件封装:把代码实现成软件,摆脱增强jdk等开发环境,了项目传播以及用户使用的可能性,降低了用户的使用成本。增强了项目的安全性,预防了因为失误而导致的代码上的缺失或错误,也防止了用户在游戏中进行不正当的竞争行为。
1.3 GUI图形界面设计:利用GUI构建鼠标键盘的监听(AWT)、登入界面、主界面、游戏界面、提示界面等,实现可视化的界面。
1.4继承、封装、多肽以及接口等都可以在代码中体现。

四、 设计性能参数

1. 数据管理能力要求

用户账号:不可使用空格,无字数限制且支持汉英文;
用户密码:6-11位字符,无特殊符号限制;

2. 准确性

为每个用户设定一个索引值,通过索引值来对用户信息进行精确修改,实现端到端数据连接。

3. 灵活性

可实现多个用户同时在线,用户与用户之间互不干扰。

4. 流畅性

采用写回策略,设置了写缓冲器,减少了访问主存的次数,即更新缓存时只有在需要将缓存里面的脏数据交换出去的时候再把数据同步到主内存里,在缓存经常会命中的情况下,性能更好,更流畅。

5. 鲁棒性(robust)

在异常和危险情况下系统生存的关键。本项目具有异常处理功能,能够捕获并响应意外情况以保证程序能稳妥地结束,计算机不会崩溃。

6. 时间特性

本项目通过定时器设置进度,可以指定想要delay(开始执行的等待时间)时间,在实现时Timer类可以调度任务,TimerTask则是通过在run()方法里实现具体任务。Timer实例可以调度多任务,它是线程安全的。当Timer的构造器被调用时,它创建一个线程,这个线程可以用来调度任务。

五、 运行结果与分析

1.项目打包

六、总结与项目自评

1.项目完成质量

按计划完成原定飞机大战项目功能目标,实现英雄机射击,加血,减血清屏等功能,并且拥有BOSS,小蜜蜂奖励机制。利用数据库存放用户数据,可以联机实现不同用户端共享数据,并且达到较好的用户体验。同时利用飞机大战定时器,碰撞,随机等机制,实现小汽车碰撞小游戏。

2.项目完成进度

按照原定计划按时完成项目,并在完成原定的飞机大战计 划上制作了一个汽车游戏。

3.项目存在问题

3.1其他用户只有与主机连接同一局域网时才可正常登入账号。
3.2游戏方式单一,用户粘性不强。
3.3缺乏多感官的游戏体验。

4.项目改进方向

4.1实现“全网通”,在用户连接不同网络时也可以正常登入账号。
4.2开发多种玩法,比如关卡模式、联机模式等。
4.3实现声音特效的嵌入。
4.4实现用户间的交流平台(聊天室)。
4.5添加更多的游戏项目。

六、 其他(项目细节)

1.游戏难度随时间增加,5%的概率生成小蜜蜂
