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.

	// 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

public class Example(MonoBehaviour):

	public extraRotation as Transform

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

Rotates the point point with rotation.

	// 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

public class Example(MonoBehaviour):

	public relativeDirection as Vector3 = Vector3.forward

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