▶ 유니티/싱글톤 - DataManager

> 정리

> 클래스
- : MonoBehaviour 삭제

> 생성자 
- private DataManager()  디셔너리 초기화

> 멤버
- private static DataManager instance;
- priavte Dictionary<int, data타입> dic타입datas;

> 인스턴스 메소드
- public static DataManager GetInstance(){
    if(DataManager.instance == null) DataManager.instance = new DataManager();
    return DataManager.instance;
}

> JSON Data 파일 직렬화
- LoadDatas();
- Resources.Load("Data/chacacter_data") <-- Object 타입 리턴
- Json파일은 TextAsset타입으로 받을수 있다.
- TextAsset textAsset = Resources.Load("Data/character_data") as TextAsset;
- string json = textAsset.text;
- data.cs 만들어논 타입[]로 직렬화 
- 디셔너리 =  타입[].ToDictionary( x => x.id);

> data 값 리턴해주는 메소드들 작성
