Resolved How can I add an animation to a Timeline via script?

Hi there, I've looked through the documentation and forum but was unable to find an answer to this question.

Is it even possible to add animations to TimelineAssets via script?

Ideally, I would want to write logic like this:

Code (CSharp):

1.     [SerializeField] private Animation animationToAdd;
2.     [SerializeField] private Animator objectToAnimate;
3.     [SerializeField] private PlayableDirector director;
4.  
5.     private void Awake()
6.     {
7.         // 1. Create new Animation Track in director's TimelineAsset
8.  
9.         // 2. Make the created animation track reference the animationToAdd
10.  
11.         // 3. Edit the director's TimelineInstance and configure the bindings to reference objectToAnimate
12.  
13.         // 4. Play the timeline
14.         director.Play();
15.     }

However, I'm not even sure how to do step 1. I am unsure of how to reference the TimelineAsset, since PlayableDirector only has a property for PlayableAsset and PlayableGraph.

 

Absolutely! Thank you very much. I was able to get it to work.
For those wondering, this is the code I wrote:

Code (CSharp):

1.     [SerializeField] private AnimationClip animationToAdd;
2.     [SerializeField] private Animator objectToAnimate;
3.     [SerializeField] private PlayableDirector director;
4.  
5.     private void Awake()
6.     {
7.         // 1. Create new Animation Track in director's TimelineAsset
8.         TimelineAsset asset = director.playableAsset as TimelineAsset;
9.         // Note - we're deleting the track if it exists already, since we want to generate everything on the spot for this example
10.         foreach (TrackAsset track in asset.GetOutputTracks())
11.             if (track.name == generatedAnimationTrackName)
12.                 asset.DeleteTrack(track);
13.         AnimationTrack newTrack = asset.CreateTrack<AnimationTrack>("MyTrackName");
14.  
15.         // 2. Make the created animation track reference the animationToAdd
16.         TimelineClip clip = newTrack.CreateClip(animationToAdd);
17.         clip.start = 0.5f;
18.         clip.timeScale = 2f;
19.         clip.duration = clip.duration / clip.timeScale;
20.  
21.         // 3. Edit the director's TimelineInstance and configure the bindings to reference objectToAnimate
22.         director.SetGenericBinding(newTrack, objectToAnimate);
23.  
24.         // 4. Play the timeline
25.         director.Play();
26.     }

 

What libraries are imported to run animation in unity 2022 with script?. Is this code okay?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.EventSystems;

What's wrong with this old code I try to compile it into unity. I'm on unity version 2021.3.10f1.
