（结对作业）基于Unity 3D游戏引擎开发的“打砖块”游戏
游戏简介：游戏在传统的打砖块游戏的基础上增加的3D的效果。游戏的操作非常简单，简单的左右方向键控制，以及鼠标对视角的控制。
编写人员： 朱俊璋，王士溥
开发工具：Unity3D 4.3
开发语言：C#
计划
任务分工：后台的游戏功能的具体实现和测试，后台代码的编写和调试 朱俊璋
游戏前端界面的设计和游戏逻辑功能的创想 王士溥
开发时间：2周
功能简介：
3D打砖块小游戏，实现基本功能，在游戏中可以通过鼠标调节camera视角以及位置——左键+移动鼠标-水平移动；右键+移动鼠标-摄像头倾斜角度；滚轮-缩放镜头。
运行游戏：
原始视角
通过鼠标调节视角
游戏界面的设计：
源代码：
BreakoutGame类：该类是游戏的主功能类，游戏的初始化和游戏界面的渲染都在此类中。该脚本绑定到游戏Main Camera组件中，使游戏在一开始时就调用此脚本。

心得体会：
这次的作业与上一次有很大的区别，需要两个人的分工和合作，这次的内容更加贴近我们兴趣和爱好，贴近实际应用，而且使用了当下流行的3d游戏引擎Unity 3D。
