我的demo保卫萝卜中的技术要点

管理类：

GameManager（单例），GameController(单例)；

一些其他的管理类（PlayerManager,AudioSourceManager,FactoryManager）作为GameManager的成员变量存在（这样也可以保证只有一个存在，并且初始化在GameManager之后）

使用到的多种设计模式

：复盘一下我用过的设计模式-CSDN博客

：： Scoll View 结合 GridLayoutGroup 组件可以实现组件的整齐排列

RectTransform

RectTransform 和 Transfrom 的区别

Inspector，Awake,OnEnable与Start之间微妙的关系

Inspector 早于 Awake 早于 OnEnable 早于 Start
