Unity 设定 Animator分割播放

项目有个需求，一整段非常长的Animator 动画， 分割成一份份的播放，我们点击相应的按钮就播放某个时间点的动画，废话不多说
新建一个空物体加上toggle group，

下面是一堆的toggle并在Group里加上父亲

	private Animator myAnimator;
    public List<Toggle> myTogglesList;
    private float playTime;
    public void Awake()
    {
        myAnimator = GameObject.Find("XXX/xxx").GetComponent<Animator>();
        myTogglesList.AddRange(transform.GetComponentsInChildren<Toggle>());
    }

    public void Start()
    {
        base.Start();
        for (int i = 0; i < myTogglesList.Count; i++)
        {
            Toggle go = myTogglesList[i];
            myTogglesList[i].onValueChanged.AddListener((bool value) => OnClickBtn(go.gameObject, value));
        }
    }

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

        if (myTogglesList[0].isOn && playTime > 0.1f)
        {
        	//Animator.Play("ANI1", 0, 0f)  第一参数 ANI1动画名  第二参数0，为0层， 第三参数 0f,为开始时间
            myAnimator.Play("ANI1", 0, 0f);
        }

        if (myTogglesList[1].isOn && playTime > 0.3f)
        {
            myAnimator.Play("ANI1", 0, 0.1f);
        }

        if (myTogglesList[2].isOn && playTime > 0.5f)
        {
            myAnimator.Play("ANI1", 0, 0.3f);
        }

        if (myTogglesList[3].isOn && playTime > 0.8f)
        {
            myAnimator.Play("ANI1", 0, 0.5f);
        }
		.........................
    }

    private void OnClickBtn(GameObject go, bool value)
    {
        switch (go.name)
        {
            case "btn01 (1)":
                myAnimator.Play("ANI1", 0, 0f);
                break;
            case "btn01 (2)":
                myAnimator.Play("ANI1", 0, 0.1f);
                break;
            case "btn01 (3)":
                myAnimator.Play("ANI1", 0, 0.3f);
                break;
            case "btn01 (3)":
                myAnimator.Play("ANI1", 0, 0.5f);
                break;
                .........................
        }
