Hello,
i'm using PUN2 and I try to handle disconnection. My goal is to display the player who is having a disconnection issue and wait for him before he is kicked out.

//Internet server  
using Photon.Pun;  
using Photon.Realtime;

public class PhotonRoom : MonoBehaviourPunCallbacks, IInRoomCallbacks  
{



    /// <summary>  
    /// Called when a remote player left the room. This PhotonPlayer is already removed from the playerlist at this time.  
    /// When your client calls PhotonNetwork.leaveRoom, PUN will call this method on the remaining clients.  
     ///  When a remote client drops connection or gets closed,   
    ///this callback gets executed.after a timeout of several seconds.   
    /// </summary>  
    /// <param name="otherPlayer"></param>

    public void OnPhotonPlayerDisconnected(Player otherPlayer)  
    {  
        Debug.Log("Player Disconnected " + otherPlayer.ActorNumber);  
        //If it is me who is having a connexion issue  
        if(otherPlayer.ActorNumber == myGroundPlayer.myActorNumber)  
        {  
            panelAttempt.SetActive(true);  
            playerName.text = myGroundPlayer.myPlayerName;  
        }  
        //If it is the other player who is having a connexion issue  
        else  
        {  
            panelAttempt.SetActive(true);  
            playerName.text = myMedolir.opponentMedolir.GetComponent<MedolirLife>().Tmp_PlayerName.text;  
        }

    }

}  

I read the documentation but somehow, the callback method is never called.

Hi @Clevereen,

Thank you for choosing Photon!

• This discussion was first posted under Photon Voice category, I have moved it to PUN category as I don't see anything Photon Voice specific.
• MonoBehaviourPunCallbacks class already extends IInRoomCallbacks so no need to implement it in PhotonRoom just override any callback method needed from there.
• OnPhotonPlayerDisconnected is from PUN classic, in PUN 2 it was replaced with IInRoomCallbacks.OnPlayerLeftRoom. Read more about Callbacks Changes.
• IInRoomCallbacks.OnPlayerLeftRoom is triggered only for remote players, for the local players you have IConnectionCallbacks.OnDisconnected (or IMatchmakingCallbacks.OnLeftRoom).

Hi @JohnTube ,

thanks for the reply. I have used the code and so far, it is not really working as intended.

//Internet server  
using Photon.Pun;  
using Photon.Realtime;

public class PhotonRoom : MonoBehaviourPunCallbacks//, IInRoomCallbacks  
{


    /// <summary>  
    /// -CLEV-  
    /// THIS METHOD WILL DISPLAY TO THIS CLIENT THE CONNEXION ISSUE THAT THE OTHER  
    /// PLAYER IS FACING  
    /// (ACCORDING TO THE ACTOR NUMBER MYSELF OR THE OTHER PLAYERS  
    /// </summary>  
    /// <param name="otherPlayer"></param>  
    private void DisplayIssue(Player otherPlayer)  
    {  
        int thePlayerId = otherPlayer.ActorNumber;  
        panelAttempt.SetActive(true);  
        if (thePlayerId == myGroundPlayer.myActorNumber)  
        {  
            playerName.text = myGroundPlayer.myPlayerName;  
            issueType.text = disconnectCause.ToString();  
        }  
        else  
        {  
            playerName.text = myMedolir.opponentMedolir.GetComponentInChildren<MedolirLife>().Tmp_PlayerName.text;  
            issueType.text = disconnectCause.ToString();  
        }

    }

    /// <summary>  
    /// IInRoomCallbacks.OnPlayerLeftRoom is triggered only for remote players,  
    /// Callbacks is triggered when a player leaves the room intentionally  
    /// </summary>  
    /// <param name="otherPlayer"></param>  
    public override void OnPlayerLeftRoom(Player otherPlayer)  
    {  
        base.OnPlayerLeftRoom(otherPlayer);  
        DisplayIssue(otherPlayer);

    }

    /// <summary>  
    /// -This is a PUN CALLBACKS-  
    /// Callback is called when THIS client player leaves a room after disconnection  
    /// MonoBehaviourPunCallbacks implements IConnectionCallbacks already.  
    ///The callback for disconnection is OnDisconnected(DisconnectionCause) which   
    ///now replaces all 3 callbacks from PUN1:   
    ///OnDisconnectedFromPhoton,  
    ///OnConnectionFail   
    ///OnFailedToConnectToPhoton.  
    /// </summary>  
    /// <param name="cause"></param>  
    public override void OnDisconnected(DisconnectCause cause)  
    {  
        base.OnDisconnected(cause);  
        disconnectCause = cause;  
        panelAttempt.SetActive(true);  
        playerName.text = myGroundPlayer.myPlayerName;  
        issueType.text = disconnectCause.ToString();

    }  
}

Here is the result with screenshot.

Problem : The connection issue is shown only when it's "too late"
It does display on both players that a connection issue has been detected, but unfortunately it is always too late.
I can't find a solution (both remote and local) to display the issue right away and then set a countdown before the timeOut is fired.
