Question

我正在开发拖放式2d教育游戏，并且坚持使用此代码。当我尝试从pos1到pos2时，它可以工作。但是，我可以再次从pos2到pos1，这是我不想要的。我尝试了一些代码但出现了一些错误是否可以使用PointerEventData解决此问题？

public class Manager : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler
{
    Vector2 pos1;
    public GameObject pos2;

    void Start()
    {
        pos1 = transform.position;
    }

    public void OnBeginDrag(PointerEventData eventData)
    {
        debug.log(eventData)
    }
    public void OnDrag(PointerEventData eventData)
    {
        transform.position = Input.mousePosition;
    }
    public void OnEndDrag(PointerEventData eventData)
    {
        float distance = Vector3.Distance(transform.position, pos2.transform.position);
        if (distance < 50)
        {
            transform.position = pos2.transform.position;
            transform.localScale = pos2.transform.localScale;
        }
        else
        {
            transform.position = pos1;
        }
    }
}

在这里，我重新编写了代码，其中包含一个bool，它限制了对象何时可以移动和不能移动。

using UnityEngine;
using UnityEngine.EventSystems;

public class Manager : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler
{
Vector2 pos1;
public GameObject pos2;
private bool canMove;

void Start()
{
    pos1 = transform.position;
    canMove = true;
}

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

public void OnDrag(PointerEventData eventData)
{
    if (canMove)
        transform.position = Input.mousePosition;

}

public void OnEndDrag(PointerEventData eventData)
{
    float distance = Vector3.Distance(transform.position, pos2.transform.position);
    if (distance < 50)
    {

        transform.position = pos2.transform.position;
        transform.localScale = pos2.transform.localScale;
        canMove = false;
    }
    else
    {
        transform.position = pos1;
    }
}

}

有没有办法在移动后将pos2停止移动到pos1？
