public [Quaternion](https://docs.unity3d.com/cn/2019.4/ScriptReference/Quaternion.html) **rotation** ;

## 描述

一个 [Quaternion](https://docs.unity3d.com/cn/2019.4/ScriptReference/Quaternion.html)，用于存储变换在世界空间中的旋转。

[Transform.rotation](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform-rotation.html) 存储 [Quaternion](https://docs.unity3d.com/cn/2019.4/ScriptReference/Quaternion.html)。可以使用 [rotation](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform-rotation.html) 来旋转 GameObject 或提供当前旋转。请勿尝试编辑/修改 [rotation](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform-rotation.html)。[Transform.rotation](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform-rotation.html) 小于 180 度。

[Transform.rotation](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform-rotation.html) 没有万向锁。

要旋转 [Transform](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform.html)，请使用 [Transform.Rotate](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform.Rotate.html)，它将使用欧拉角。

如果要匹配在检视面板中看到的值，请对返回的 [Quaternion](https://docs.unity3d.com/cn/2019.4/ScriptReference/Quaternion.html) 使用 [Quaternion.eulerAngles](https://docs.unity3d.com/cn/2019.4/ScriptReference/Quaternion-eulerAngles.html) 属性。

```
using UnityEngine;

// Transform.rotation example.

// Rotate a GameObject using a Quaternion.
// Tilt the cube using the arrow keys. When the arrow keys are released
// the cube will be rotated back to the center using Slerp.

public class ExampleScript : MonoBehaviour
{
    float smooth = 5.0f;
    float tiltAngle = 60.0f;

void Update()
    {
        // Smoothly tilts a transform towards a target rotation.
        float tiltAroundZ = Input.GetAxis("Horizontal") * tiltAngle;
        float tiltAroundX = Input.GetAxis("Vertical") * tiltAngle;

// Rotate the cube by converting the angles into a quaternion.
        Quaternion target = Quaternion.Euler(tiltAroundX, 0, tiltAroundZ);

// Dampen towards the target rotation
        transform.rotation = Quaternion.Slerp(transform.rotation, target,  Time.deltaTime * smooth);
    }
}
```

在以上示例中，[rotation](https://docs.unity3d.com/cn/2019.4/ScriptReference/Transform-rotation.html) 由四元数进行描述。有关更多建议，请参阅 [Unity 中的旋转和方向](https://docs.unity3d.com/cn/2019.4/Manual/QuaternionAndEulerRotationsInUnity.html)。
