Can I change the region in runtime using PUN?

LucasCavataio

Hi,

I've been trying for a long time to find a way to change the region in runtime, but I can't find it... I've tried the LoadBalancingClient class but it doesn't work, I don't know if it's because I use the PhotonNetwork class for everything else... I would like this to work (code below) but I think it should not be that simple hahaha

using Photon.Pun;
using Photon.Realtime;
using UnityEngine;


public class RegionManager : MonoBehaviourPunCallbacks
{
    bool showRegionMenu = false;


    [SerializeField] GameObject regionMenu;


    string currRegion;


    public bool changingRegion { get; private set; }


    public void UpdateRegion(string code)
    {
        PhotonNetwork.Disconnect();


        changingRegion = true;
        currRegion = code;
    }


    public override void OnDisconnected(DisconnectCause cause)
    {
        PhotonNetwork.ConnectToRegion(currRegion);
        
    }


    public override void OnConnectedToMaster()
    {
        changingRegion = false;
    }


    public void ShowHideRegionMenu()
    {
        showRegionMenu = !showRegionMenu;


        if (showRegionMenu) regionMenu.SetActive(true);
        else regionMenu.SetActive(false);
    }
}

Every time I get this error

OperationResponse 230: ReturnCode: 32767 (Regions mismatch). Parameters: {} Server: MasterServer Address: 91.199.81.131:5055

Is it possible that in PUN this cannot be done?

Best Regards!

For some reason, the internally stored AuthToken is not discarded before you call PhotonNetwork.ConnectToRegion(currRegion). The token is provided for one region and you need to authenticate on the Name Server again to get a new one.

Are you maybe not running a recent PUN version?

You could try to clear the token yourself. Before ConnectToRegion, set PhotonNetwork.AuthValues.Token = null.

Hi!

Thanks for answering and so quickly!

I have tried what you have told me and Token is an object protected with an internal set, even so I have tried to make it public in the LoadbalancingPeer class, where this object is declared, but I still get the same message in the console: "Disconnected from Server: InvalidAuthentication" and the initial error of this discussion... I am currently using PUN2 Version 2.41, I don't know if there is a higher version than this...

My code looks like this...

using Photon.Pun;
using Photon.Realtime;
using UnityEngine;


public class RegionManager : MonoBehaviourPunCallbacks
{
    public Launcher launcher;


    bool showRegionMenu = false;


    [SerializeField] GameObject regionMenu;


    string currRegion;


    public bool changingRegion { get; private set; }


    public void UpdateRegion(string code)
    {
        changingRegion = true;


        currRegion = code;


        PhotonNetwork.Disconnect();


        //This give me an error because is a protected object
        PhotonNetwork.AuthValues.Token = null;
    }


    public override void OnDisconnected(DisconnectCause cause)
    {
        if (!changingRegion) return;


        try
        {
            PhotonNetwork.ConnectToRegion(currRegion);
        }
        finally
        {
            changingRegion = false;
            PhotonNetwork.ConnectUsingSettings();
            launcher.errorText.text = "Can't connect to " + currRegion + " servers... Try again later";
            MenuManager.Instance.OpenMenu("error");
        }
        


    }


    public override void OnConnectedToMaster()
    {
        changingRegion = false;
        
    }


    public void ShowHideRegionMenu()
    {
        showRegionMenu = !showRegionMenu;

        regionMenu.SetActive(showRegionMenu);
    }
}

Is this a recent question or did it get a new timestamp when I got it out of the spam queue?

Invalid Authentication is a different error from the first one and will depend on how you setup Authentication for your AppId and how it's used client side.

Please mail us to [email protected] and name the AppId and the region you are setting in ConnectToRegion(currRegion).

Hi Tobias!

Thank you for your answer and sorry for the inconvenience, I was able to solve it a while ago, and the truth is that it works correctly for me, in my game I have not received any type of complaint about it from the users.

I leave here what the script looks like in case someone has the same problem that I had at the time.

Thank you very much and best regards!

Thanks for the update, Lucas. Much appreciated.

Glad this works in-game :)
