其实这个教程很早就收藏了就是被20个小时时长给吓到了一直没开始。终于在七月中旬的时候开始动手跟着做了。
最近一直加班也很忙，参与的第一个项目计划在年底上线，也是有项目经验的人了哈哈。然后拖拖拉拉的一直跟着教程做，只是个半成品敌人部分还没做，以我目前的精力就先做到这里了。原教程链接：第一人称射击游戏教程2.0【已完结】_哔哩哔哩_bilibili
https://www.bilibili.com/video/BV1J8411d75s/?spm_id_from=333.999.0.0&vd_source=6b664fb3236a2f45f99b9eb3868cdf31
教程讲的很细，有C#和Unity基础的做到我现在这样没什么太大的问题，但教程讲的也有点慢，所以时长才会达到二十小时，我看的时候是1.5倍速看的。
主要功能：枪械有AK、消音m4、格洛克、霰弹枪、狙击枪；玩家行走、奔跑、跳跃、下蹲；
不同枪械不同的装弹方式、瞄准状态、准星动态变化、全自动半自动模式切换、武器库切换武器、随机弹道、武器的检视功能。

由于间隔时间太长本篇笔记就不从头开始讲了，只把核心脚本代码和Demo源码放出来，脚本代码也有对应的注释，感兴趣的话大家可以结合原教程博主和下面的核心代码一起看。
