像DoTween插件一样链式调用方法

请先看这是DoTween使用示例

AboutMeBack?.onClick.AddListener(() => {
            AboutCanvasGroup?.DOFade(0, 0.82F)
            .SetEase(Ease.OutCirc)
            .OnComplete(() => {
                AboutCanvasGroup.gameObject.SetActive(false);
            });
        });

下面是我们的简单实现方法，其实就是每次调用完一个方法后让他返回类的实例然后就可以接着继续调用

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
