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
