在unity3D中有没有拖放UI按钮的方法？

using UnityEngine;
using UnityEngine.EventSystems;
using UnityEngine.UI;

public class DragAndDropButton : MonoBehaviour, IPointerDownHandler, IBeginDragHandler, IDragHandler, IEndDragHandler
{
    private RectTransform rectTransform;
    private Canvas canvas;
    private CanvasGroup canvasGroup;

    private void Awake()
    {
        rectTransform = GetComponent<RectTransform>();
        canvas = GetComponentInParent<Canvas>();
        canvasGroup = GetComponent<CanvasGroup>();
    }

    public void OnPointerDown(PointerEventData eventData)
    {
        // 按下按钮时的处理逻辑
        Debug.Log("Button Down");
    }

    public void OnBeginDrag(PointerEventData eventData)
    {
        // 开始拖拽按钮时的处理逻辑
        canvasGroup.blocksRaycasts = false;
        Debug.Log("Begin Drag");
    }

    public void OnDrag(PointerEventData eventData)
    {
        // 拖拽按钮时的处理逻辑
        rectTransform.anchoredPosition += eventData.delta / canvas.scaleFactor;
        Debug.Log("Dragging");
    }

    public void OnEndDrag(PointerEventData eventData)
    {
        // 结束拖拽按钮时的处理逻辑
        canvasGroup.blocksRaycasts = true;
        Debug.Log("End Drag");
    }
}
