Hey Guys I have some problem about Photon. Here is The code;

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;
using Photon.Realtime;

public class FinishManager : MonoBehaviour
{
    private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.CompareTag("Legs"))
        {
            collision.gameObject.GetComponent<PhotonView>().RPC("Win", RpcTarget.All, collision.gameObject); /*Here is the error line*/
        }
    }


    [PunRPC]
    public void Win(GameObject player)
    {
        PhotonNetwork.Destroy(player);
    }

}

The problem is this:

CodePudding user response：

You can only use PhotonNetwork.Destroy if the object was created using PhotonNetwork.Instantiate, regardless of it having a photon view component.

From Docs:

Destroying networked objects works only if they got created with PhotonNetwork.Instantiate(). Objects loaded with a scene are ignored, no matter if they have PhotonView components.

The client who is calling PhotonNetwork.Destroy must have control of the object being destroyed.

If your FinishManager component has control of the object, you can simply call Destroy when the collision happens.

private void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.gameObject.CompareTag("Legs"))
    {
        var photonView = collision.gameObject.GetComponent<PhotonView>();
        if (photonView)
        {
            PhotonNetwork.Destroy(photonView);
        }
    }
}

If your FinishManager does not have control of the object, the object in question will need to initiate Destroy iteself. For this you can use an RPC.

private void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.gameObject.CompareTag("Legs"))
    {
        var photonView = collision.gameObject.GetComponent<PhotonView>();
        if (photonView)
        {
            photonView.RPC("DestroyMyself", photonView.Owner);
        }
    }
}

The RPC method needs to be on the object that was instantiated.

private void DestroyMyself()
{
    PhotonNetwork.Destroy(gameObject);
