DrawGizmo 绘制Gizmo

Inherits from System.Attribute

The DrawGizmo attribute allows you to supply a gizmo renderer for any Component.

DrawGizmo属性允许你提供一个gizmo渲染器，用于任意组件Component。

Note: This is an editor class. To use it you have to place your script in Assets/Editor inside your project folder. Editor classes are in the UnityEditor namespace so for C# scripts you need to add "using UnityEditor;" at the beginning of the script.
注意：这是一个编辑器类，如果想使用它你需要把它放到工程目录下的Assets/Editor文件夹下。编辑器类在UnityEditor命名空间下。所以当使用C#脚本时，你需要在脚本前面加上 "using UnityEditor"引用。

At the moment you can only supply gizmo drawers for engine-components. All gizmo drawing methods need to be static.

目前只能提供engine-components的gizmo绘制。所有gizmo绘制方法必须是静态的。
