基于J2ME的小球快跑游戏摘要：手机是人们日常生活中所用的非常频繁的通信工具。随着JAVA技术的不断更新提高，J2ME技术的出现，使得手机游戏越来越成为我们关注的焦点。J2ME技术目前最流行的就是在制作手机游戏方面，JAVA手机的出现使得这一技术更有它的用武之地，发挥着他灵活、轻便、快捷的作用。J2ME平台被是最杰出的手机游戏手机游戏平台，它一些非常重要的特征对开发者都有很大益处。因为J2ME应用在不同设备上都是便携式的，他们常常可以在网络上下载和执行。本设计通过DriftBall和GameView等类进行小球快跑游戏设计，最后编程实现了全过程。关键词：J2MEDriftBallGameView目录设计内容及过程……………4（1）游戏策划………………… 4（2）设计背景………………..4（3）游戏框架设计…………… 5游戏主菜单的开发…………5（1）WelcomeView类的代码框架………… 5（2）WelcomeView类的主要成员方法.………6（3）WelcomeThread类的开发…………8（4）菜单界面的用户交互事件处理……….……9游戏界面模块的开发…………………… 11（1）GameView的成员变量11（2）GameThread类的代码框架13（3）GameMenuThread类的开发13游戏中各个图层的开发……………………..15（1）地图图层的开发…………………. 15（2）其他图层的开发与实现………………… 18游戏后台逻辑的开发…………………....21（1）小球的运动控制21（2）小球的碰撞检测25传感器计算模块的开发27（1）BallListener类的开发27（2）RotateUtil类的开发28设计总结参考文献…………31设计内容及过程本设计针对小球快跑实现了新游戏、选关、恭喜过关，继续或冲完等过程。可以清楚的演示各个画面的切换和一些游戏开发的类库。游戏策划本游戏从类型上看属于动作类通关游戏，因此在游戏开发前进行的策划中需要考虑到诸如剧情规划、关卡设计等内容剧情规划：由于本游戏主要是以玩法取胜，而不是靠游戏情节来吸引玩家，所以游戏的剧情的规划可以尽量简单或者干脆没有关卡设计：关卡设计是本游戏的一个重点，在关卡设计的时候，如何保证难易程度的循环渐进和关卡之间的互异性以及关卡的可玩性是需要重视的问题。目标受众：本游戏的操作方式十分简单，各个年龄阶段的玩家都可以快速掌握。目标平台：本游戏的目标平台为MTK。呈现技术：本游戏的游戏画面采用了图元技术，所以地图的设计也是一个重点，同时增强了游戏的空间感。（2）设计背景游戏中，首先必须要有个主应用程序类，其次，为了把程序的画面呈现出来，就是要有画布；为了比较容易管理地图、增加或修改地图比较方便，应该把地图和画布分开。这其中需要先了解游戏中应用到的类。WelcomeView类继承自SurfaceView类，其主要负责播放欢迎动画和显示游戏主菜单。GameView类继承自SurfaceView，其主要负责游戏主画面的渲染。GameMenuThread负责实现游戏中菜单的逐行的效果。GameMap类负责负责提供游戏中的地图信息，GameMap中存储了所有关卡的信息，并对外提供了方法用于获得指定关卡的地图信息。DriftBall类继承自Activity，其主要负责在不同的View之间进行切换，同时也负责处理用户单击屏幕事件。BaiiListener类继承自SensorListener类，气质要负责监听手机姿态的变化并将捕获到的数据传递给RotateUtil进行分析计算。RotateUtil类主要负责接收手机姿态的变化数据，并根据一系列算法计算出在这种姿态下的小球的运动方向。(3)游戏框架设计游戏基本框架图：图1小球快跑游戏基本框架游戏主菜单的开发WelcomeView类的代码框架代码如下：packagewyf.wpf;
