前言
随着经济的发展和社会节奏的加快，人们所面对的压力越来越大，总想寻求一种方式来释放自己的压力。而我国科技水平在高速发展，计算机已经广泛应用于人们的日常生活中。因此，现在越来越多的人想借着计算机来达到释放自己压力，给自己充电的目的。而电脑游戏尤其是休闲小游戏正好可以起到这种效果。因此，休闲小游戏一直深受人们的喜欢。
6人学生小团队用一周时间根据实训发布任务设计拓展一个潜艇大战的小游戏。该小游戏可以在游戏中选择自己喜欢的模式：“单人”“双人”以及难易程度，还可以查看游戏规则及说明，最终以分数为目标完成该游戏。
提示：以下是本篇文章正文内容，下面案例可供参考
一、任务概述
1.1目标
通过游戏程序增加编程兴趣，提高编程水平。随着编程水平的提高，力争设计出人们喜欢的休闲小游戏，给人们带来愉悦的心灵享受。给那些长期因学习工作压力比较大的人们提高一种释放压力的途径，使得他们更有激情工作同时实现他们的人生价值。

二、游戏规则
本系统主要是完成潜艇大战游戏的基本操作。用户可以自己练习和娱乐。本系统需要满足以下几点要求:
（1）利用方向键来改变军舰的运行方向（P2玩家根据WASD来控制战舰）;
（2）按空格（S）发射导弹，击中敌人得分，P1，P2玩家分别计分，分数高者获胜；
（3）根据游戏设置难度（有两个选择“易”、“难”）；
（4）主页的模式选择（有单人双人两种模式）；
（5）游戏过程中，每个玩家3枚导弹，每使用一枚导弹自动恢复；
（6）玩家可根据菜单进行开始、暂停和退出的选择；
