            王曦的心得：

                   软件工程第二次作业的结对编程，我和我的队友万炼炼设计了一个基于unity3d的魔方游戏，通过在网上边学习边操作的方式，了解了unity3d游戏引擎的基本机制， 同时也深刻体会到要做出一个软件，团队合作的重要性。在这次结对编程中，我主要担任的是代码的编写，以及游戏逻辑的设计。万炼炼同学主要负责的是游戏资源的管理，以及游戏的整体设计。unity是一款强大的3d游戏引擎，目前市面上大部分流行的3d游戏都可以用u3d来设计，我们设计的魔方游戏虽然简单，但也付出了一定的心血，其中涉及到对每一层魔方的旋转，还包括横向旋转和竖向旋转。在游戏中还要兼顾到玩家的体验，比如在游戏中可以旋转视图来让玩家更好地来观察魔方的几个面的变化。

演示效果：

 

      在游戏的基础上我们还添加了快捷输入公式功能，能够让你在输入公式过后魔方自动执行步骤。由于这只是基础版的，游戏也只是开发出了一个雏形，后来可以添加一些计时功能，或者能够网络对战。

性能分析：                                        

     由于是自带的3d引擎，感觉也比较耗性能，特别是3d渲染，还有对每一帧的更新也比较吃cpu和显卡，程序自身比较简单，这次能够在unity3d上运行一个小小的demo也算是一种学习吧。
