前言：
笔者是跟着哔站课程（Trigger）学习unity才去学习的C#，并且C语言功底尚存，所以只是简单地跟着课程将unity所用的C#语言的关键部分进行了了解，然后在后期unity学习过程中加以深度学习。如需完善的C#知识，推荐CSDN博主：呆呆敲代码的小Y - 链接: link
具体学习部分如下，建议将后面的源代码复制到vs打开后按顺序查看，其中EP标注的是笔者的课程集数
需要用到哪个部分取消该部分定义及Main语句里的注释即可，部分内容有所串通，不使用时重新注释，防止调试时出现问题
所有内容只需要简单搜索就可以找到解释
其中比较重要的部分是public，static等的理解，以及父子集的运用，推荐还是跟着课程学习为好
#region 和 #endregion 是用来分区的，便于找到所需部分，不用该部分时，可以点击 #region 左边的箭头进行缩略
