Unity 如何设定 Animator分割播放

            myTogglesList[i].onValueChanged.AddListener((bool value) => OnClickBtn(go.gameObject, value));
        }
    }

    {
     //playTime  得到当前时间点
        playTime = myAnimator.GetCurrentAnimatorStateInfo(0).normalizedTime;
        Debug.Log(playTime);

            myAnimator.Play("ANI1", 0, 0f);
        }
