unity3D中判断动画是否播放完毕

bool IsAnimationPlaying(GameObject objWithAnimation,string animationName)
{
return  objWithAnimation.animation.IsPlaying(animationName)&&objWithAnimation.animation[animationName].normalizedTime<1.0f;
}

IEnumerator WaitForAnimationPlayOver(GameObject objWithAnimation,string animationName)
{
yield return new WaitForSeconds(objWithAnimation.animation[animationName].length);
}
