Quaternion.LookRotation

static function LookRotation (forward : Vector3, upwards : Vector3 = Vector3.up) : Quaternion

Description

Creates a rotation that looks along forward with the the head upwards along upwards

Logs an error if the forward direction is zero.

JavaScripts

// Most of the time you can use:
// transform.LookAt instead

var target : Transform;
function Update () {
var relativePos = target.position - transform.position;
var rotation = Quaternion.LookRotation(relativePos);
transform.rotation = rotation;
}

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
public Transform target;
void Update() {
Vector3 relativePos = target.position - transform.position;
Quaternion rotation = Quaternion.LookRotation(relativePos);
transform.rotation = rotation;
}
}

class example(MonoBehaviour):

public target as Transform

def Update():
relativePos as Vector3 = (target.position - transform.position)
rotation as Quaternion = Quaternion.LookRotation(relativePos)
transform.rotation = rotation
