Quaternion.operator * 运算符乘法

# [Quaternion](Quaternion.html).operator * 运算符 乘法

static *operator ** (*lhs* : Quaternion, *rhs* :
Quaternion) : Quaternion

*Description* 描述

Combines rotations lhs and rhs.

组合旋转 lhs 和 rhs。

Rotating a point first with lhs and then with rhs is the same as rotating the
point by the combined rotation. Note that rotations are not commutative: lhs *
rhs does not equal to rhs * lhs.

旋转一个点，首先用 lhs，然后用 rhs 旋转，与使用组合旋转相同。注意旋转不可交换： lhs*rhs 不等于 rhs*lhs.

```
using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public Transform extraRotation;
	public void Awake() {
		transform.rotation *= extraRotation.rotation;
	}
}
```

```
// Applies the rotation of
// extraRotation to the current rotation
//应用extraRotation的旋转给当前旋转
var extraRotation : Transform;
transform.rotation *= extraRotation.rotation;
```

• static *operator ** (*rotation* : Quaternion, *point*
: [Vector3](../Vector3/Vector3.html)) : [Vector3](../Vector3/Vector3.html)

*Description* 描述

Rotates the point point with rotation.

用 rotation 旋转 point 点。

```
using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public Vector3 relativeDirection = Vector3.forward;
	void Update() {
		Vector3 absoluteDirection = transform.rotation * relativeDirection;
		transform.position += absoluteDirection * Time.deltaTime;
	}
}
```

```
// Moves the object along relativeDirection
// Usually you would use transform.Move for this
//沿着relativeDirection移动物体
//通常你应该使用transform.Move移动
var relativeDirection = Vector3.forward;

function Update () {
	var absoluteDirection = transform.rotation * relativeDirection;
	transform.position += absoluteDirection * Time.deltaTime;
}
```
