Timeline change animation playback speed problem

Hi

I want to change the playback speed of target animator in runtime because timescale changes the speed of everything. (So I cannot use the time dilation track in the default playable package).

I used timeline playable wizard to create a custom track of my own to alter the target animator speed. However although the script worked, the playback speed did not change. Is there anything wrong with my script? Or is there any work around on this issue?

I also tried using Chronos's lock clock function but Chronos doesn't seem to work in timeline either.

here is my code:

Code (CSharp):

1.  
2.  
3. public class AnimatorPlaySpeedMixerBehaviour : PlayableBehaviour
4. {
5.     float m_DefaultSpeed;
6.  
7.     Animator m_TrackBinding;
8.     bool m_FirstFrameHappend;
9.  
10.     public override void ProcessFrame(Playable playable, FrameData info, object playerData)
11.     {
12.         m_TrackBinding = playerData as Animator;
13.  
14.         if (!m_TrackBinding)
15.             return;
16.  
17.         if (!m_FirstFrameHappend)
18.         {
19.             m_DefaultSpeed = m_TrackBinding.speed;
20.             m_FirstFrameHappend = true;
21.         }
22.  
23.         int inputCount = playable.GetInputCount ();
24.  
25.         float blendedSpeed = 0f;
26.         float totalWeight = 0f;
27.         float greatestWeight = 0f;
28.         int currentInputs = 0;
29.  
30.  
31.         for (int i = 0; i < inputCount; i++)
32.         {
33.             float inputWeight = playable.GetInputWeight(i);
34.             ScriptPlayable<AnimatorPlaySpeedBehaviour> inputPlayable = (ScriptPlayable<AnimatorPlaySpeedBehaviour>)playable.GetInput(i);
35.             AnimatorPlaySpeedBehaviour input = inputPlayable.GetBehaviour ();
36.  
37.             blendedSpeed += input.Speed * inputWeight;
38.             totalWeight += inputWeight;
39.  
40.  
41.             if (inputWeight > greatestWeight)
42.             {
43.                 greatestWeight = inputWeight;
44.             }
45.  
46.             if (!Mathf.Approximately (inputWeight, 0f))
47.                 currentInputs++;
48.          
49.         }
50.  
51.         m_TrackBinding.speed = blendedSpeed + m_DefaultSpeed * (1f - totalWeight);
52.         if (currentInputs != 1 && 1f - totalWeight > greatestWeight)
53.         {
54.         }
55.     }
56.     public override void OnGraphStop(Playable playable)
57.     {
58.         m_TrackBinding.speed = m_DefaultSpeed;
59.         m_FirstFrameHappend = false;
60.     }
61.  
62. }

 

Yes it is part of the timeline, is there any way to change the playback speed of a timeline animation clip then? I think this would be a fairly common need when working with timeline. Time dilation in the default playable package slows everything including UI items, which is not what I want to achieve.

 

Is there any update on this? I have a similar requirement. I have a bunch of nested timeline assets, with a master timeline driving a bunch of other timelines. I want to slow down the animation in a child timeline while the master keeps running at the same speed. Global time dilation doesn't help.

 

Sorry I wasn't clear about what I meant. Yes you can change animation speed per clip, but then the value is fixed for the clip. What I need is a way that works like time dilation but is not global: e.g. reduce the speed of this animation to .5 for 10 frames, then continue playing it at speed of 1 for the remainder of its duration
