            {
                instance = new DownLoadManager();
            }
            return instance;
        }
    }

    // 생성자를 private으로 만들어 외부에서 인스턴스를 생성하지 못하게 함
    private DownLoadManager() { }
}

public class UIComponents : MonoBehaviour

    [SerializeField] private UILoadingBar uiLoadingBar;



    private void Start()
    {
        this.loadingStartBtn.onClick.AddListener(() => {
            this.uiLoadingBar.DownLoadStarting();
        
        });

      

    }
