c#实现unity UI拖动自动吸附

以下是使用C#实现Unity UI拖动自动吸附的示例代码：

using UnityEngine;
using UnityEngine.EventSystems;

public class SnapToGrid : MonoBehaviour, IBeginDragHandler, IDragHandler {
    public float gridSize = 10f;

    public void OnBeginDrag(PointerEventData eventData) {
        // Disable layout element to allow free movement
        var layoutElement = GetComponent<LayoutElement>();
        if (layoutElement != null) {
            layoutElement.ignoreLayout = true;
        }
    }

    public void OnDrag(PointerEventData eventData) {
        // Snap to grid during drag
        transform.position = new Vector3(
            Mathf.Round(eventData.position.x / gridSize) * gridSize,
            Mathf.Round(eventData.position.y / gridSize) * gridSize,
            transform.position.z
        );
    }

    public void OnEndDrag(PointerEventData eventData) {
        // Enable layout element to restore original position
        var layoutElement = GetComponent<LayoutElement>();
