画面遷移時でも使えるように

DontDestroyOnLoadを追加する

if (mInstance == null)
{
	GameObject go = new GameObject("PhotonManager");
	mInstance = go.AddComponent<PhotonManager>();
	DontDestroyOnLoad(go);
}

部屋に参加したときのPhotonNetwork.PlayerListについて

(2024/9/17時点)

部屋に参加した(JoinedRoom)ときの、相手の情報が、PhotonNetwork.PlayerListに登録されてない場合があったため、 0.1秒遅らせて、処理したら、相手の情報が、載っていた。

OnCreatedRoom() 

このクライアントがルームを作成して入室すると呼び出されます。 OnJoinedRoom ()も呼び出されます
