Unity Multiplayer Photon Unity Networking Problem

Hello. I'm new to unity (I'm creating one of my first games ). And i have a "problem".
My code is:

MenuGlowne (MainMenu)

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class MenuGlowne : MonoBehaviour
7. {
8.  
9.     MenadzerPolaczen mp;
10.     public InputField ifNick;
11.  
12.     void Start()
13.     {
14.         DontDestroyOnLoad(gameObject);
15.         mp = GetComponent<MenadzerPolaczen>();
16.     }
17.  
18.     // Odpala mape gdy BtnGraj
19.     public void BtnGraj ()
20.     {
21.         if (ifNick.text.Length >= 4)
22.         {
23.             PhotonNetwork.playerName = ifNick.text;
24.             mp.Polacz();
25.         }
26.  
27.     }
28.  
29. }

Menadzer Polaczen (ConnectingMenager)

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.SceneManagement;
5.  
6. public class MenadzerPolaczen : Photon.MonoBehaviour {
7.  
8.     void Update ()
9.     {
10.         if (Input.GetKeyDown(KeyCode.L))
11.         {
12.             Gracz.Debuguj();
13.         }
14.     }
15.  
16.     public void Polacz ()
17.     {
18.         PhotonNetwork.ConnectUsingSettings("EarlyAcces_June2019_ClosedAlpha_0.0.1");
19.     }
20.  
21.     void OnGUI ()
22.     {
23.         GUI.Label(new Rect(50, 30, 200, 20), PhotonNetwork.connectionStateDetailed.ToString());
24.     }
25.  
26.     void OnJoinedLobby()
27.     {
28.         SceneManager.LoadScene(1);
29.     }
30.  
31.     void OnPhotonRandomJoinFailed()
32.     {
33.         PhotonNetwork.CreateRoom(null);
34.     }
35.  
36.     void OnLevelWasLoaded(int level)
37.     {
38.         if (level != 0)
39.         {
40.             PhotonNetwork.JoinRandomRoom();
41.         }
42.     }
43.  
44.     void OnPhotonPlayerConnected(PhotonPlayer pp)
45.     {
46.         if (PhotonNetwork.isMasterClient)
47.         {
48.             photonView.RPC("GraczWszedl", PhotonTargets.AllBuffered, pp);
49.         }
50.     }
51.  
52.     void OnPhotonPlayerDisconnected (PhotonPlayer pp)
53.     {
54.  
55.     }
56.  
57.     [PunRPC]
58.     void GraczWszedl(PhotonPlayer pp)
59.     {
60.         Gracz gracz = new Gracz();
61.         Gracz.gracze.Add(gracz);
62.         gracz.nick = pp.NickName;
63.         gracz.pp = pp;
64.     }
65.  
66.     [PunRPC]
67.     void GraczWyszedl (PhotonPlayer pp)
68.     {
69.  
70.     }
71.  
72.     void OnCreatedRoom()
73.     {
74.         photonView.RPC("GraczWszedl", PhotonTargets.AllBuffered, PhotonNetwork.player);
75.     }
76. }

Gracz (Player)

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Gracz {
6.     public string nick = "";
7.     public PhotonPlayer pp;
8.  
9.     public static List<Gracz> gracze = new List<Gracz>();
10.  
11.     public static void Debuguj()
12.     {
13.         Debug.Log("Game list debug! Player count: " + gracze.Count + "all players:: ");
14.             foreach (var gracz in gracze)
15.             {
16.                 Debug.Log(gracz.nick + ", ");
17.             }
18.     }
19. }
20.  

All is nice, but when i get down BtnGraj (Button play) I see this in consle
https://zapodaj.net/61dabae5dd0ba.png.html


PS: Sorry for my English

Grasz = Player
Wszedl = Connected
Wyszedl = Disconnected
BtnGraj = Button Play

 

The error is on line 88 on MenadzerPolaczen, but i delated my comments in the script so now it’s line 74 in MenadzerPolaczen

 

You could fix this by not calling the RPC "GraczWszedl". Everyone else knows when a client joins, as there is a callback for that.
IInRoomCallbacks has OnPlayerEnteredRoom. Do the PUN Basics Tutorial.

 

So if I just delete RPC "GraczWszedl" it will work?

 

Ok, it work. I dont get the error, but the "player list" says 0 players.

Please read and code the Basics Tutorial.

 

I have the same error, do you already know how to fix it?
