Unity Script Reference – Quaternion.operator *

Quaternion.operator *

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

Description

Combines rotations lhs and 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.

JavaScript

// Applies the rotation of
// extraRotation to the current rotation

var extraRotation : Transform;
transform.rotation *= extraRotation.rotation;

using UnityEngine;
using System.Collections;

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

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    public extraRotation as Transform

    def Example():
        transform.rotation *= extraRotation.rotation

static operator * (rotation : Quaternion, point : Vector3) : Vector3

Description

Rotates the point point with rotation.

JavaScript

// Moves the object along relativeDirection
// Usually you would use transform.Translate for this

var relativeDirection = Vector3.forward;

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

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;
    }
}

import UnityEngine
import System.Collections

class example(MonoBehaviour):

    public relativeDirection as Vector3 = Vector3.forward

    def Update():
        absoluteDirection as Vector3 = (transform.rotation * relativeDirection)
        transform.position += (absoluteDirection * Time.deltaTime)
