It seems that I set Collision Detection - Continuous, but it's all the same
like
this

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

public class DND : MonoBehaviour, IBeginDragHandler, IDragHandler
{
    public Transform transform;
    public Vector2 vector2;
    private void Awake()
    {
        transform = GetComponent<Transform>();
    }

    public void OnBeginDrag(PointerEventData eventData)
    {
        Debug.Log("OnBeginDrag");
    }

    public void OnDrag(PointerEventData eventData)
    {
        Debug.Log("OnDrag");
        vector2 = Camera.main.ScreenToWorldPoint(eventData.position);
        transform.position = new Vector3(vector2.x, vector2.y, 0);
    }
}

Answer 1

Who moves physics through the transform.
