Unity3d让某个物体一直正对着相机

//将以下代码绑定到相机上

using UnityEngine;

using System.Collections;

 

public class LookatScipt : MonoBehaviour {

 

// Use this for initialization

void Start () {

 

}

 

// Update is called once per frame

void Update () {

float x = Input.GetAxis ("Horizontal");//旋转相机

float y = Input.GetAxis ("Vertical");

gameObject.transform.RotateAround(gameObject.transform.position, Vector3.up, x);

gameObject.transform.RotateAround(gameObject.transform.position, Vector3.right, y);

 

GameObject cube = GameObject.Find("Cube");//要正对着相机的物体

cube.transform.RotateAround(gameObject.transform.position, Vector3.up, x);

cube.transform.RotateAround(gameObject.transform.position, Vector3.right, y);

}

}
