Question Photon PUN 2.0 Problem

Hello! I am using 2022.1.2.1f1 version of unity.

I am currently following a tutorial from BlackThornProd:

For some reason, a method is not being called.

Here are the scripts:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Photon.Pun;
5. using Photon.Realtime;
6. using UnityEngine.UI;
7.  
8. public class LobbyManager : MonoBehaviourPunCallbacks
9. {
10.     public InputField roomInputField;
11.     public GameObject lobbyPanel;
12.     public GameObject roomPanel;
13.     public Text roomName;
14.  
15.     public RoomName roomNamePrefab;
16.     public Transform contentObject;
17.     List<RoomName> roomNamesList = new List<RoomName>();
18.  
19.     public float timeBetweenUpdates = 1.5f;
20.     float nextUpdateTime;
21.  
22.     public List<PlayerItem> playerItemsList = new List<PlayerItem>();
23.     public PlayerItem playerItemPrefab;
24.     public Transform playerItemParent;
25.  
26.     private void Start()
27.     {
28.         PhotonNetwork.JoinLobby();
29.     }
30.  
31.     public void OnClickCreate()
32.     {
33.         if (roomInputField.text.Length >= 1 && roomInputField.text.Length <= 10)
34.         {
35.             PhotonNetwork.CreateRoom(roomInputField.text);
36.         }
37.     }
38.  
39.     public override void OnJoinedRoom()
40.     {
41.         base.OnJoinedRoom();
42.  
43.         lobbyPanel.SetActive(false);
44.         roomPanel.SetActive(true);
45.         roomName.text = PhotonNetwork.CurrentRoom.Name;
46.  
47.         UpdatePlayerList();
48.     }
49.  
50.     public override void OnRoomListUpdate(List<RoomInfo> roomList)
51.     {
52.         base.OnRoomListUpdate(roomList);
53.  
54.         if (Time.time >= nextUpdateTime)
55.         {
56.             UpdateRoomList(roomList);
57.             nextUpdateTime = Time.time + timeBetweenUpdates;
58.         }
59.     }
60.  
61.     void UpdateRoomList(List<RoomInfo> list)
62.     {
63.         foreach (RoomName name in roomNamesList)
64.         {
65.             Destroy(name.gameObject);
66.         }
67.  
68.         roomNamesList.Clear();
69.  
70.         foreach(RoomInfo room in list)
71.         {
72.             RoomName newRoom = Instantiate(roomNamePrefab, contentObject);
73.             newRoom.SetRoomName(room.Name);
74.  
75.             roomNamesList.Add(newRoom);
76.         }
77.     }
78.  
79.     public void JoinRoom(string roomName)
80.     {
81.         PhotonNetwork.JoinRoom(roomName);
82.     }
83.  
84.     public void OnClickLeaveRoom()
85.     {
86.         PhotonNetwork.LeaveRoom();
87.     }
88.  
89.     public override void OnLeftRoom()
90.     {
91.         base.OnLeftRoom();
92.  
93.         roomPanel.SetActive(false);
94.         lobbyPanel.SetActive(true);
95.     }
96.  
97.     public override void OnConnectedToMaster()
98.     {
99.         base.OnConnectedToMaster();
100.  
101.         PhotonNetwork.JoinLobby();
102.     }
103.  
104.     public void UpdatePlayerList()
105.     {
106.         foreach (PlayerItem item in playerItemsList)
107.         {
108.             Destroy(item.gameObject);
109.         }
110.  
111.         playerItemsList.Clear();
112.  
113.         if (PhotonNetwork.CurrentRoom == null)
114.         {
115.             return;
116.         }
117.  
118.         foreach (KeyValuePair<int, Player> player in PhotonNetwork.CurrentRoom.Players)
119.         {
120.             PlayerItem newplayerItem = Instantiate(playerItemPrefab, playerItemParent);
121.             newplayerItem.SetPlayerInfo(player.Value);
122.  
123.             if (player.Value == PhotonNetwork.LocalPlayer)
124.             {
125.                 newplayerItem.ApplyLocalChanges();
126.             }
127.  
128.             playerItemsList.Add(newplayerItem);
129.         }
130.     }
131.  
132.     public override void OnPlayerEnteredRoom(Player newPlayer)
133.     {
134.         base.OnPlayerEnteredRoom(newPlayer);
135.  
136.         UpdatePlayerList();
137.     }
138.  
139.     public override void OnPlayerLeftRoom(Player otherPlayer)
140.     {
141.         base.OnPlayerLeftRoom(otherPlayer);
142.  
143.         UpdatePlayerList();
144.     }
145. }

and:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using Photon.Pun;
6. using Photon.Realtime;
7.  
8. public class PlayerItem : MonoBehaviour
9. {
10.     public Text playerName;
11.     public Color highlightColor;
12.     public GameObject leftArrowButton;
13.     public GameObject rightArrowButton;
14.     private Image backgroundImage;
15.  
16.     private void Start()
17.     {
18.         backgroundImage = GetComponent<Image>();
19.     }
20.  
21.     public void SetPlayerInfo(Player _player)
22.     {
23.         playerName.text = _player.NickName;
24.     }
25.  
26.     public void ApplyLocalChanges()
27.     {
28.         backgroundImage.color = highlightColor;
29.  
30.         leftArrowButton.SetActive(true);
31.         rightArrowButton.SetActive(true);
32.     }
33. }
34.  

ApplyLocalChanges(), for whatever reason, is not being called. I am a unity beginner programmer, and I have no idea how Photon works either. Thanks for the help.

 

I tried posting in the Photon forums, but have not yet received a reply, so I decided to post in here.
