创建两个Panel分别为PanelA,PanelB，修改一下文字和B的颜色以便区分开来

给两个Panel分别添加DragAndSelectIndex.cs

具体代码如下

using UnityEngine;
using System.Collections;
using UnityEngine.UI; 
using UnityEngine.EventSystems;
public class DragAndSelectIndex : MonoBehaviour, IPointerDownHandler, IDragHandler {  
    

    public void OnPointerDown (PointerEventData data) {  
    
        this.transform.SetSiblingIndex(1);  
    
    }  


    public void OnDrag(PointerEventData eventData)
    {
    
        this.transform.SetSiblingIndex(0);  
        transform.position=Input.mousePosition;
    }

    public void OnPointerUp(PointerEventData eventData)
    {
        this.transform.SetSiblingIndex(0);  

    }



}

代码很简单这里不再赘述

运行效果
