Question

JavaScript => public var rotation: Quaternion;
C# => public Quaternion rotation;

Description 描述

The rotation of the rigdibody.

刚体的旋转角度。

Rigidbody.rotation allows you to get and set the rotation of a Rigidbody using the physics engine. If you change the rotation of a Rigibody using Rigidbody.rotation, the transform will be updated after the next physics simulation step. This is faster than updating the rotation using Transform.rotation, as the latter will cause all attached Colliders to recalculate their rotation relative to the Rigidbody.

Rigidbody.rotation允许你使用物理引擎获取或设置刚体的位置。如果你使用Rigidbody.rotation更改刚体的位置，该变换将在下次物理模拟时更新。这比更新位置使用Transform.rotation更快，后者将导致所有附加的碰撞器重新计算相对刚体的位置。

If you want to continuously rotate a rigidbody use MoveRotation instead, which takes interpolation into account.

如果你想连续移动刚体使用MoveRotation替代，其考虑了内插值。

JavaScript:

	function Start () {
		GetComponent.<Rigidbody>().rotation = Quaternion.identity;
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Start() {
        GetComponent<Rigidbody>().rotation = Quaternion.identity;
    }
}
