IPointerEnterHandler, IPointerExitHandler

鼠标进入，移出事件，闪烁问题

新建一个UIImage,挂载下面的这个脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;//IPointerEnterHandler, IPointerExitHandler 

public class UI_MouseEnter : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler
{

    public void OnPointerEnter(PointerEventData eventData)
    {
        Debug.Log("Hello");
        transform.localScale = new Vector3(0,0,0);
    }

    public void OnPointerExit(PointerEventData eventData)
    {
        Debug.Log("Bye");
        transform.localScale = new Vector3(1, 1, 1);
    }
}

直接改变 UI 按钮的localScale，就会出现闪烁的BUG
