1、背景：鼠标悬浮在UI上出现提示框

cs 复制代码

public class SpecialParam_list : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler
{
    public void OnPointerEnter(PointerEventData eventData)
    {
        TipBox.Instance.ShowBox(Input.mousePosition, value);
    }

    public void OnPointerExit(PointerEventData eventData)
    {
        TipBox.Instance.HideBox();
    }

}




using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TipBox : UnitySingleton<TipBox>
{
    SpecialFyALand_Panel fyALand_Panel;
    GameObject tioObj;
    public float offset = 1;
    [SerializeField]
    private float threshold = 1f;
    public  void ShowBox(Vector2 pos, string ac  )
    {
     
       
        if (tioObj == null)
        {
            tioObj = ResMgr.GetInstance().Load<GameObject>("TipBox", ResourcesType.UIPrefabs);
            tioObj.transform.SetParent(GameObject.Find("Canvas").transform);
            tioObj.transform.SetAsLastSibling();
        } 
        TipBoxInfo tipBoxInfo = tioObj.GetComponent<TipBoxInfo>();
        tipBoxInfo.InitData( ac );
        tioObj.SetActive(true);
        tioObj.transform.SetAsLastSibling();
        tipBoxInfo.transform.position = new Vector2(pos.x, pos.y) + new Vector2(0, 0) * offset;
        //tipBoxInfo.transform.position = new Vector3(pos.x, pos.y, 0) + new Vector3(963, 539, 0) * offset;

    }
    public void HideBox()
    {
        if (tioObj != null&& tioObj.activeSelf)
            tioObj.SetActive(false);
    }
}

2、鼠标一旦出现在图片边缘弹框就会不停的闪烁

3、解决方案：将弹框包含所有的物体的RaycastTarget去掉

PS：个人猜测原因是弹窗的移入导致出发了pointenter事件
