[Unity]FirebaseでDatabaseReferenceの存在を確認する

More than 3 years have passed since last update.

UniRx使用

IObservable<bool> ExistsAsync (DatabaseReference reference)
{
    var subject = new AsyncSubject<bool> ();
    reference.GetValueAsync ().ContinueWith (x => {
        if (x.IsFaulted) {
            Debug.LogError ("Fail to read guildInfo");
            // エラーを飛ばす
            subject.Dispose ();
        } else if (x.IsCompleted) {
            DataSnapshot snapshot = x.Result;
            subject.OnNext (snapshot.Exists);
            subject.OnCompleted ();
        }
    });
    return subject;
}
