Unity音ゲー制作にてオブジェクトが生成されない

前提・実現したいこと

Unityで初めてのゲーム制作で音楽ゲーム(音ゲー)を制作しています。
現在、Jsonファイルを読み込んでオブジェクトを生成するという工程を行っていますがそこで問題が起きています。

発生している問題

読み込みはちゃんとできているはずですがオブジェクトが一つしか生成されません。

Debug.Logなどで実際に動作した時の変数の値やどこを実行したのかなどデバッグはされたのでしょうか？

しました。ちゃんと読み込まれてはいました。ネスト化しているところも問題ないです

なのであればCheckNextNotesのif文の中が実行されていないとかSpawnNotesにてインスタンスが生成されているはずなのに表示されないとか具体的な問題点が分かるかと思いますので、そういった情報を書かれるべきかと思います。

なるほど... Unity初心者なのであまり理解していませんでした。勉強不足でした。

LoadCSVにてiをインクリメントしている場所を間違えていませんか？

C#
1void LoadCSV(){
2    string json = Resources.Load (filePass).ToString();
3    InputJson inputJson = JsonUtility.FromJson<InputJson>(json);
4    Debug.Log(inputJson.name);
5    int i=0;
6
7    for(int j=0;j < inputJson.Notes.Length; j++){
8        timing=((float)inputJson.Notes[j].num*4+inputJson.Notes[j].LPB)/100;
9        _timing[i] = timing;
10        _lineNum[i] = inputJson.Notes[j].block;
11    }
12    i++;
13}
