前言

这个功能主要是因为 每个动画片段的播放速度不一样，需要获取到速度来计算 播放时长。

获取某个动画片段的播放速度，并且得到播放时长

1.获取速度

 /// <summary>/// 播放动画/// </summary>/// <param name="obj_">带有Animator的Obj</param>/// <param name="animatorName_">动画名称</param>public virtual void ObjPlayAnimator(Animator obj_, string animatorName_, Action<GameObject> action_){//获取动画组件var anim = obj_.GetComponent<Animator>();float speed_ = 1;//默认给1获取AnimatorController中的所有层级：
//AnimatorController controller = animator.runtimeAnimatorController as AnimatorController;
//AnimatorControllerLayer[] layers = controller.layers;
//遍历每个层级，获取层级中的状态机：
//foreach (AnimatorControllerLayer layer in layers)
//{
//    AnimatorStateMachine stateMachine = layer.stateMachine;
//    // 这里可以进一步处理状态机中的逻辑
//}//获取AnimatorController中的0层级AnimatorController controller = anim.runtimeAnimatorController as AnimatorController;AnimatorStateMachine stateMachine =controller.layers[0].stateMachine;//获取层级中的状态机ChildAnimatorState[] states = stateMachine.states;//遍历状态机，for (int i = 0; i < states.Length; i++){if (states[i].state.name== animatorName_)//判断得到你要的动画速度  {speed_ = states[i].state.speed;}}Debug.LogError("speed_="+ speed_);//播放anim.Play(animatorName_, 0, 0);//计算动画时长float time_ = GetAnimatorLength(anim, animatorName_) * (1 / speed_);//播放完成后 返回事件StartCoroutine(OverAnimation(obj_.gameObject, action_, time_));}IEnumerator OverAnimation(GameObject Obj, Action<GameObject> action_, float itme_){yield return new WaitForSeconds(itme_);action_.Invoke(Obj);}

2.计算时长

代码如下（示例）：

 /// <summary>/// 获得animator下某个动画片段的时长方法/// </summary>/// <param animator="animator">Animator组件</param> /// <param name="name">要获得的动画片段名字</param>/// <returns></returns>public float GetAnimatorLength(Animator animator, string name){//动画片段时间长度float length = 0;AnimationClip[] clips = animator.runtimeAnimatorController.animationClips;//Debug.Log(clips.Length);foreach (AnimationClip clip in clips){// Debug.Log(clip.name);if (clip.name.Equals(name)){length = clip.length;break;}}return length;}

总结

好记性不如烂笔头
