摘要：这个小程序是关于弹珠的小游戏，游戏比较简单，以小球的速度来区分游戏的难易。

该小程序是用左右键控制游戏的开始和挡板的方向，不让小球落到底端，当然，小球的速度越快，该游戏的难度也就越大。

此程序利用C#程序编写，在visual studio 2005的环境下进行调试运行的。

弹珠原理：碰撞基本都是参照“反射定理”的,就是出射角=入射角,但是做碰撞时需要角度。

碰撞的运动和球的方向有关,球的方向有好几种。

有8向的,也有4向的。

保证小球横向上在允许范围之内运动，当触发时就反方向运动，和当出了球拍的可击打范围就停止运行了。

对于该程序开发，必须达到以下要求：1、熟悉.NET开发环境，能够使用C#语言在.NET平台上独立设计、开发WINDOWS应用程序。

2、掌握C#语言的异常处理技术，能够使用.NET各种调试方法调试代码，掌握帮助的使用方法。

3、掌握常用控件以及控件的常用属性的使用方法。

4、界面要做到简洁易懂，具有人性化等特点。

5、程序没有在使用过程中不存在任何的问题。

6、可选功能应全面，可以实施速度的选择，游戏的是否继续，还有记录的保存。

我选择弹珠游戏这个课题，用代码控制游戏的等级，运用不同的函数来控制球的速度和方向，游戏简单而有趣。

二、总体设计2.1．系统开发平台系统采用Microsoft Visual Studio 2005三、详细说明在此弹球游戏中，对于球与挡板的位置，借助于x与y坐标的调整来实现统计，从而确定球落在板上后球的下一次方向。

同时借助于Visual Studio中的控件来控制小球的速度。

此项游戏的计分运用函数count++，打中一个砖块即可得到一分，看你最多能打多少砖块。

３.1系统实施1．主界面：打开弹珠游戏,开始运行程序，跳出一个Forms界面，用户在此时必须先选择符合自己能力的游戏等级，然后才可以进行游戏。

如图1所示。
