Map selection in Photon PUn 2

[Iambleb]

Hey Guys! I’m using Photon PUN 2 to make a multiplayer FPS game.

In the lobby, where all the players are waiting for the host to start the game, I want it that so when the host clicks on a button (which has the map name on it) and start the game in that scene, bringing all the players to it.

How do I do this?

Here is my code:

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

public class Launcher : MonoBehaviourPunCallbacks
{
    public static Launcher Instance;
    
    [SerializeField] TMP_InputField roomNameInputField;
    [SerializeField] TMP_Text errorText;
    [SerializeField] TMP_Text roomNameText;
    [SerializeField] Transform roomListContent;
    [SerializeField] GameObject roomListItemPrefab;
	[SerializeField] Transform playerListContent;
	[SerializeField] GameObject PlayerListItemPrefab;
    [SerializeField] GameObject startGameButton;

    
    
    void Awake()
    {
        Instance = this;
    }
    
    void Start()
    {
        Debug.Log("Connecting to Master");
        PhotonNetwork.ConnectUsingSettings();
    }

    public override void OnConnectedToMaster()
    {
        Debug.Log("Connected to Master");
        PhotonNetwork.JoinLobby();
        PhotonNetwork.AutomaticallySyncScene = true;
    }

    public override void OnJoinedLobby()
    {
        MenuManager.Instance.OpenMenu("title");
        Debug.Log("Joined Lobby");
        PhotonNetwork.NickName = "Player " + Random.Range(0, 1000).ToString("0000");
    }

     public void CreateRoom()
    {
        if(string.IsNullOrEmpty(roomNameInputField.text))
        {
            return;
        }
        PhotonNetwork.CreateRoom(roomNameInputField.text);
        MenuManager.Instance.OpenMenu("loading");
    }

    public override void OnJoinedRoom()
    {
        MenuManager.Instance.OpenMenu("room");
        roomNameText.text = PhotonNetwork.CurrentRoom.Name;

        Player[] players = PhotonNetwork.PlayerList;

        foreach(Transform child in playerListContent)
        {
            Destroy(child.gameObject);
        }

        for(int i = 0; i < players.Length; i++)
		{
		    Instantiate(PlayerListItemPrefab, playerListContent).GetComponent<PlayerListItem>().SetUp(players[i]);
		}
    }

    public override void OnCreateRoomFailed(short returnCode, string message)
    {
        errorText.text = "Room Creation Failed: " + message;
        MenuManager.Instance.OpenMenu("error");
    }

    public void StartGame()
    {
        PhotonNetwork.LoadLevel(1);
    }

    public void LeaveRoom()
    {
        PhotonNetwork.LeaveRoom();
        MenuManager.Instance.OpenMenu("loading");
    }


    public void JoinRoom(RoomInfo info)
    {
        PhotonNetwork.JoinRoom(info.Name);
        MenuManager.Instance.OpenMenu("loading");
    }

    public override void OnLeftRoom()
    {
        MenuManager.Instance.OpenMenu("title");
    }

   public override void OnRoomListUpdate(List<RoomInfo> roomList)
	{
		foreach(Transform trans in roomListContent)
		{
			Destroy(trans.gameObject);
		}

		for(int i = 0; i < roomList.Count; i++)
		{
			if(roomList[i].RemovedFromList)
				continue;
			Instantiate(roomListItemPrefab, roomListContent).GetComponent<RoomListItem>().SetUp(roomList[i]);
		}
	}

	public override void OnPlayerEnteredRoom(Player newPlayer)
	{
		Instantiate(PlayerListItemPrefab, playerListContent).GetComponent<PlayerListItem>().SetUp(newPlayer);
	}
}
