Unity使用PlayableAPI 动态播放动画

1.初始化animator，创建Playable图，创建动画Playable

private void InitAnimator(GameObject headGo)
{if (headGo){_headAnimator = headGo.GetComponent<Animator>();if (_headAnimator){_headAnimator.cullingMode = AnimatorCullingMode.AlwaysAnimate;}else{_headAnimator = headGo.AddComponent<Animator>();}if(_headAnimator != null){playableGraph = PlayableGraph.Create();playableGraph.SetTimeUpdateMode(DirectorUpdateMode.GameTime); // 根据需要选择更新模式// 创建一个输出节点curPlayableOutput = AnimationPlayableOutput.Create(playableGraph, "Animation", _headAnimator);}}
}

2.播放动画

     public void PlayExpression(string clipName,float time = 0){// 加载动画片段var clip = GetClip(clipName);if (clip != null){if (time > 0){animaStartTime = Time.time;isUpdate = true;clipLength = clip.length;loopNum = 1;}else{ResertAnimaParam();}// 将动画剪辑转换为PlayablecurClipPlayable = AnimationClipPlayable.Create(playableGraph, clip);//设置动画开始时间curClipPlayable.SetTime(0);// 将Playable连接到输出curPlayableOutput.SetSourcePlayable(curClipPlayable);playableGraph.Play();}else{
#if UNITY_EDITORDebug.LogError("Expression clip not found: " + clipName);
#endif}}
