커스텀 애니메이션커브를 담은 스크립(HnineCurves.cs)을 만들고 AnimationCurve를 적당한 이름으로 선언해 줍니다.

인스펙터에 가보면 이처럼 에디트할 수있는 창을 띄울 수 있겠죠.

클릭해서 원하는 모양의 이지값을 아래처럼 만들어 줍니다.

이렇게 만든 커브를 다음과 같이 DOTween에 사용할 수 있습니다.

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using DG.Tweening;
using UnityEngine.SceneManagement;

public delegate void ProgressDelegate(float progress);

public class LoadSceneAsyncProgress : MonoBehaviour {
	public Image ProgressBar;
	public CanvasGroup CG_Loading;

	void Start() {
		CG_Loading.DOFade (0.5f, 0.5f).SetEase (Ease.Linear).SetLoops (-1, LoopType.Yoyo);
		StartCoroutine(LoadSceneAsyncByName("FamilyHomeVI_SR", OnLoadLevelProgressUpdate));

	}
	
	public static IEnumerator LoadSceneAsyncByName(string nextLevel, ProgressDelegate progressDelegate) {
		AsyncOperation async = SceneManager.LoadSceneAsync(nextLevel);
	
		while (!async.isDone) {
			progressDelegate (async.progress);
			async.allowSceneActivation = async.progress > 0.8;
			yield return null;
		}
	}

	private void OnLoadLevelProgressUpdate(float progress) {
		ProgressBar.fillAmount = progress;
		Debug.Log ("async.progress: " + progress);
	}
}
