Unity3D UI图片躲避鼠标效果

MouseEffect挂载image上的脚本
方法是通过鼠标位置和图片原始位置获得方向，乘上距离。

using UnityEngine;

public class MouseEffect : MonoBehaviour
{
   
    public float speed = 5.0f;
    float dis;
    Vector3 oriPos;
    Vector3 newPos;
    Vector3 mousePos;
    // Update is called once per frame
    private void Start()
    {
   
        oriPos = transform.position;
    }
    void Update()
    {
   
        mousePos = Input.mousePosition;
        dis = Vector3.Distance(mousePos, oriPos);

        if (dis < 250)
        {
   
            transform.localScale = 2 * Vector3.one - (Vector3.one * dis / 250) ; 

            Vector3 vectoerAB = (mousePos - oriPos).normalized;
            newPos = vectoerAB *  -(250 - dis);
            transform
