PlayableGraph 概述: PlayableGraph是一组API 

PlayableGraph常用API：
PlayableGraph
AnimationPlayableOutput: IPlayableOutPut 输出节点
AnimationMixerPlayable: Iplayable 动画混合
AnimationClipPlayable: Iplayable 动画剪辑

可借用第三方可视化工具：
graph-visualizer 插件 进行查看，下载自行百度

废话不多说 ，直接上代码：

 1 using UnityEngine;
 2 using UnityEngine.Animations;
 3 using UnityEngine.Playables;
 4 
 5 public class TestPlayable : MonoBehaviour
 6 {
 7     private Animator m_Animator;
 8 
 9     [SerializeField]
10     private AnimationClip m_AnimationClip;
11     private PlayableGraph m_PlayableGraph;
12     private AnimationPlayableOutput m_AnimationPlayableOutput;
13 
14     void Awake()
15     {
16         m_Animator = GetComponent<Animator>();
17         //创建画布
18         m_PlayableGraph = PlayableGraph.Create("testGraph");
19         //为画布创建一个输出节点
20         m_AnimationPlayableOutput = AnimationPlayableOutput.Create(m_PlayableGraph, "OutPut", m_Animator);
21         Test1();
22     }
23 
24     void Test1()
25     {
26         //画布上创建一个动画剪辑，作为输入节点
27         AnimationClipPlayable animationClipPlayable = AnimationClipPlayable.Create(m_PlayableGraph, m_AnimationClip);
28         //连线（设置输出节点的输入源为动画剪辑）
29         m_AnimationPlayableOutput.SetSourcePlayable(animationClipPlayable, 0);
30         //播放
31         m_PlayableGraph.Play();
32     }
33 }
