Beginner little rookie , I hope it's like taking notes and recording what I've learned , Also hope to help the same entry-level people , I hope the big guys can help correct it ~ Tort made delete .

Two 、unity3d Some commonly used expressions of rotation angle and their meanings in

1、this.transform.rotation（ Attribute variables ）

Used to store the rotation of the current object in world space , It's a quaternion （ It's not degrees , It's some sin,cos The combination of ）.

transform.rotation The rotation angle of is not fixed , After declaration, you can assign a value .

2、this.transform.eulerAngles

Euler angle of the object relative to the world coordinates

3、this.transform.localEulerAngles

Euler angle of the object relative to the parent object

4、Quaternion.identity（ Value type ）

No rotation —— It is equivalent to Quaternion(0,0,0,0)

notes ： read-only ：Quaternion.identity The rotation angle is fixed , No assignment is allowed after declaration

5、Quaternion.eulerAngles

Convert Euler angle into quaternion format and save
