前言

超级玛丽这款游戏是很多人童年经典的回忆，是一种简单的大众的游戏，自从计算机实现以来，深受广大电脑玩家的喜爱。并且随着社会的快速发展，人们的生活节奏越来越快，人们对于童年的美好已经不愿意仅仅停留在回忆阶段。
《超级玛丽升级版》游戏是用java语言实现，采用了swing技术进行了界面化处理，设计思路用了面向对象思想。

主要设计

功能主要设计

本系统主要是完成超级玛丽游戏的基本操作。本系统需要满足以下几点要求：
(1) 在开始界面按空格键进入游戏。
(2) 利用方向键来控制马里奥的运动。
(3) 碰撞检测：
A.马里奥在运动的过程中如果碰到障碍物则停止运动,在移动到悬崖上方是会掉下去，并失去一条生命。
B.对于有些敌人，如果马里奥跳到敌人头顶上，则敌人消失，否则马里奥失去一条生命。
(4)马里奥顶到金币会增加分数，当马里奥失去3条生命时游戏结束。

界面主要设计

选取和谐Q版的图片，使画面色彩和谐自然。

固定游戏界面大小与初始显示位置。

游戏采用900600像素显示，对于马里奥和障碍物选用6060像素
的正方图片，对于较大的障碍物分割成多个60*60的小正方形。

大悬崖场景：

场景借鉴了魂斗罗

为了提升游戏的可玩性，加了一个隐藏的过关要点

总结

通过此次的《超级玛丽升级版》游戏实现，让我对JAVA的相关知识有了进一步的了解，对java这门语言也有了比以前更深刻的认识。

java的一些基本语法，比如数据类型、运算符、程序流程控制和数组等，理解更加透彻。java最核心的核心就是面向对象思想，对于这一个概念，终于悟到了一些。
