UNity UGUI 2D图片追随问题

Unity中，GameObject追随问题的一种解决办法。针对UGUI的2D情况。

贴出代码

using UnityEngine; using System.Collections; public class JellyMove : MonoBehaviour {     public Transform path;    public  float speed; void Start () {     } // Update is called once per frame void Update () {     }     void FixedUpdate()     {         transform.position = Vector3.MoveTowards(transform.position,path.position, speed * Time.deltaTime);         Rigidbody2D rigidBody= transform.GetComponent<Rigidbody2D>();         var lookPos = path.position - transform.position;         float x = Vector2.Angle(lookPos,Vector2.right);         float y = Vector2.Angle(lookPos, Vector2.up);         Vector2 moveVec = new Vector2(x,y);         if (lookPos.x < 0)         {             rigidBody.MoveRotation(y);         }else         {             rigidBody.MoveRotation(-y);         }     } } Secne场景如下

然后运行状态下，拖动被追随物体，就可以随便跑了，各个方向也是正确的
