Hello, When players join it will add the player object to the List i defined which is

    public static List players = new List();

like this way

    players.Add(player);

so the problem is that the new players will get the list with only the players who joins after them :s so i decided to use OnPhotonSerializeView like this way

        void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info) {
            if(stream.isWriting) {
                Debug.Log("writing players");
                stream.SendNext(players);
            } else {
                Debug.Log("Receiving players");
                players = (List)stream.ReceiveNext();
            }
        }

and added photon view to the gameobject with script like this

i got two problems, first when sending player i get this error

    Exception: cannot serialize(): System.Collections.Generic.List`1[Player]
