如何得到动画帧数，控制unity动画播放

在Unity动画控制中，如何获得当前动画已经播放到的帧呢？
其实可以通过 clip.frameRate，clip.length，及normalizedTime来计算出具体的帧。

//当前动画机播放时长
currentTime = anim.GetCurrentAnimatorStateInfo(0).normalizedTime;
//动画片段长度
float length = anim.GetCurrentAnimatorClipInfo(0)[0].clip.length;
//获取动画片段帧频
float frameRate = anim.GetCurrentAnimatorClipInfo(0)[0].clip.frameRate;
//计算动画片段总帧数
float totalFrame = length / (1 / frameRate);
//计算当前播放的动画片段运行至哪一帧
int currentFrame = (int)(Mathf.Floor(totalFrame * clipTime) % totalFrame);（

clipTime改为currentTime

） Debug.Log(" Frame: " + currentFrame + “/” + totalFrame);

float Remap(float tex, float min, float max, float slefMin = 0, float slefMax = 1)
{
    return (min + (tex - slefMin) * (max - min) / (slefMax - slefMin));
}
IEnumerator OnUpdate()
{
    while (true)
    {
        yield return new WaitForEndOfFrame();
        //当前动画播放时长
        float currentTime = anim.GetCurrentAnimatorStateInfo(0).normalizedTime;
        //总时长
        float length = animLength[SelectType.ToString()].length;
        //总帧数 length / (1 / tempclip.frameRate)
        float totalFrame=animLength[SelectType.ToString()].totalFrame;
        //播放时长映射成帧数
        int currentFrame =(int) Remap(currentTime, 0, totalFrame); 
                 
        if (currentFrame >= totalFrame)
        {
           break;
        }
    }
    Debug.Log("结束");
    GameRoot.Instance.StopCoroutine(OnUpdate());

}
