Bug Playable.Pause() not work

Hello, I'm trying to play an animation clip using Playable and make it paused at the beginning, but the Pause method didn't work. Is it a bug? Or I need call some else method?

Here's the code:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Animations;
3. using UnityEngine.Playables;
4.  
5. [RequireComponent(typeof(Animator))]
6. public class PlayableTest : MonoBehaviour
7. {
8.     [SerializeField]
9.     private AnimationClip _clip;
10.  
11.     private Animator _animator;
12.     private PlayableGraph _graph;
13.  
14.     private void Start()
15.     {
16.         _animator = GetComponent<Animator>();
17.         _graph = PlayableGraph.Create(nameof(PlayableTest));
18.  
19.         var clipPlayable = AnimationClipPlayable.Create(_graph, _clip);
20.         clipPlayable.Pause(); // NOT WORK!!
21.  
22.         var animOutput = AnimationPlayableOutput.Create(_graph, "Test Pause", _animator);
23.         animOutput.SetSourcePlayable(clipPlayable);
24.  
25.         _graph.Play();
26.     }
27.  
28.     private void OnDestroy()
29.     {
30.         _graph.Destroy();
31.     }
32. }

 

I found that is because Unity will reset animation Playables to Playing state When the following events occur:

• When binding a Playable to AnimationPlayableOutput(call 'SetSourcePlayable' method).
• When Animator's renderer become visible or invisible and its cullingMode is not 'AlwaysAnimate'.

 

In this case, whenever I set a Playable's play state to Paused, it cloud be reset to Playing by OnBecomeVisible/OnBecomeInvisible event. Is this reasonable?

 

Unity Issue Tracker - Paused Playable starts playing when a GameObject&#39;s visible state is changed and Animator::SyncPlayStateToCulling() is called (unity3d.com)
