Unity Script Reference – Quaternion.operator *

Quaternion.operator *

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

Description

Combines rotations lhs and rhs.

Rotating by the product lhs * rhs is the same as applying the two rotations in sequence, lhs first and then rhs. Note that this means rotations are not commutative, so lhs * rhs does not give the same rotation as 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)
