Unity3D实现指⽰灯亮灭效果
这周有个需求是实现控制指⽰灯亮灭的效果。实现起来很简单，但是找到这个⽅法还费了点时间。
先看效果。
原理是利⽤了标准着⾊器中的⾃发光属性，通过开关⾃发光属性来控制灯的亮灭。
具体看步骤：
1.创建⼀个⾃发光的材质球，合理设置主要颜⾊与⾃发光颜⾊，⾦属度Metallic与平滑度Smoothness⾃⼰看需求设置
2.再创建⼀个⽆⾃发光的材质球
3.如何⽤代码控制⾃发光的开关内？
若不想了解从哪⼉找到控制的地⽅的，这⼀段可以跳过，直接看⼯程。
既然在编辑器能够勾选⾃发光，那⼀定有⼀个编辑器脚本可以控制这部分。那么这个编辑器脚本在哪⼉呢？你需要从unity官⽹下载你对应版本的内置着⾊器源码，下载回来的⽂件夹中Editor⽂件夹下的StandardShaderGUI.cs即是标准着⾊器编辑器的源码。
