Hi @Amobear,

Thank you for choosing Photon!

You can make use of "App Stats" to know how many players are connected.
To get the list of regions in PUN2, implement IConnectionCallbacks.OnRegionListReceived(RegionHandler).

I use IConnectionCallbacks and override OnRegionListReceived(RegionHandler) but this method don't call.

Hi @Amobear,

Make sure to register the callbacks implemented by calling PhotonNetwork.AddCallbackTarget(this).
Read ".Net Callbacks".
Or simply extend MonoBehaviourPunCallbacks.
If you enable "SupportLogger" from PhotonServerSettings for debugging purposes, you can check if OnRegionListReceived is really called or not.

If you have a "Fixed Region" in PhotonServerSettings, the callback will not be triggered as the client will try to connect to that specific fixed region instead of fetching the list of available regions from the server. If you do not call ConnectUsingSettings, the callback may not be triggered.

I created a class:

public class RegionMode : MonoBehaviourPunCallbacks
{

    // Use this for initialization
    void Start() {
        PhotonNetwork.ConnectUsingSettings();
    }

    public override void OnRegionListReceived(RegionHandler regionHandler)
    {
        base.OnRegionListReceived(regionHandler);
        Debug.Log("REGION " + regionHandler.EnabledRegions.ToString());
    }
} 

and attack it to scene but this method still don't call.Where am I wrong? Thanks.

Hi @Amobear,

What do you have in your "Fixed Region" field under "App Settings" inside PhotonServerSettings?
It should be left empty or blank.

Assuming you are connecting to Photon Cloud of course and not self-hosted Photon Server.
