Quaternion.Inverse 求反

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public Transform target;
	void Update() {
		transform.rotation = Quaternion.Inverse(target.rotation);
	}
}

// Sets this transform to have the opposite rotation of the target
//设置这个变换具有target相反的旋转
var target : Transform;
function Update () {
	transform.rotation = Quaternion.Inverse(target.rotation);
}
