Unity3D学习：飞碟游戏进化版

上一个做的飞碟游戏虽然是功能也齐全，但是我感觉架构不是很好有点紊乱，不利于后期维护以及改进，所以我按照一个完整的架构重新做了一次，思路更清晰，而且还添加了更多的功能。这次的飞碟游戏是两个关卡，50分上第二关，100分通第二关，而且可以任意切换模式（运动学非刚体模式和物理刚体模式，前者没有刚体组件，后者加刚体组件）

讲讲规则先：一开始就是第一关，默认模式为运动学非刚体模式，还是按空格发射飞碟（一次一个），一个发射期间不能发射第二个，一个飞碟如果没打中会在一定时间内消失，飞碟消失才能发射下一个飞碟，鼠标左键射击子弹，按数字键2切换模式为物理刚体模式，按数字键1切换到运动学非刚体模式。

上个效果图（由于比较难射中，所以我把飞碟大小弄大一些，分数显示被遮住了）：

接下来讲一下设计思路，游戏架构如下

DiskModule类挂在飞碟预设上，用来处理触发器事件（飞碟碰到子弹或者地板时触发）

DiskFactory类专门生产飞碟，所有生产飞碟的细节都在这里实现，会根据每个关卡生产不同大小以及颜色的飞碟，并且回收飞碟以便再次加以利用

Recorder类只负责记录分数或者重置分数

Userface类处理用户界面逻辑

CCActionManager类实现运动学的动作，比如运动学非刚体的飞碟发射

PhysicsActionManager类实现物理刚体学动作，比如子弹的发射以及刚体飞碟的发射

SceneController类加载场景以及调用各个其他类来实现功能，比如Userface调用子弹或者飞碟射击要通过SceneController根据不同模式以及关卡来调用相应的动作管理器

具体代码如下，（注释已经把代码思想写的很清楚）：
