为什么 Transform.position 在 2D 中总是返回 0,0,0？

Question

单击按钮时，我调用 Shoot () 函数，它应该在角色的位置创建一颗子弹，但在场景的中心创建。

在 PlayerShooter 代码中的 Start() 处，我检查它是否返回正确的 trasform.position 值，但是当在 Shoot () 函数中按下按钮时它返回 0,0,0

我发现子弹是在预制件的位置上产生的，而不是在预制件位置的实例化对象上，我该如何解决这个问题？

拍摄代码：

using Photon.Pun;
using UnityEngine;

public class PlayerShooter : MonoBehaviour
{
    [SerializeField] private GameObject _bullet;
    [SerializeField] private float _distanceMultiplier;
    public void Shoot()
    {
        if (PhotonNetwork.PlayerList.Length > 1)
        {
            PhotonNetwork.Instantiate(_bullet.name, transform.position, transform.rotation);
        }
    }
}

角色移动脚本：

using UnityEngine;
using Photon.Pun;

[RequireComponent(typeof(Rigidbody2D), typeof(CapsuleCollider2D))]
public class PlayerMover : MonoBehaviour
{
    [SerializeField] private float _speepMoving, _speedRotation;
    private Rigidbody2D _rigidbody;
    private Vector2 _direction;
    private PhotonView _view;
    [HideInInspector] public FixedJoystick joystick;
    private void Start()
    {
        _view = GetComponent<PhotonView>();
        _rigidbody = GetComponent<Rigidbody2D>();
    }
    private void FixedUpdate()
    {
        if (_view.IsMine && PhotonNetwork.PlayerList.Length > 1)
        {
            _rigidbody.velocity = new Vector2(joystick.Horizontal * _speepMoving, joystick.Vertical * _speepMoving);
            RotatePlayer();
        }
    }
    private void RotatePlayer()
    {
        _direction = new Vector2(joystick.Horizontal, joystick.Vertical);
        if (_direction != Vector2.zero)
        {
            Quaternion toRotation = Quaternion.LookRotation(Vector3.forward, _direction);
            _rigidbody.MoveRotation(Quaternion.Lerp(transform.rotation, toRotation, _speedRotation * Time.deltaTime));
        }
    }
}

我已经用这段代码完成了：

using Photon.Pun;
using UnityEngine;
using UnityEngine.UI;

public class PlayerShooter : MonoBehaviour
{
    [SerializeField] private GameObject _bullet;
    [SerializeField] private float _distanceMultiplier;

    [HideInInspector] public Button shootButton;

    private void Start()
    {
        shootButton.onClick.AddListener(delegate () { Shoot(); });
    }

    public void Shoot()
    {
        if (PhotonNetwork.PlayerList.Length > 1)
        {
            PhotonNetwork.Instantiate(_bullet.name, transform.position + transform.up * _distanceMultiplier, transform.rotation);
        }
    }
}
