Syntax

[Serializable]
public abstract class TrackAsset : PlayableAsset, IPlayableAsset, IPropertyPreview, ISerializationCallbackReceiver

Remarks

Derive from TrackAsset to implement custom timeline tracks. TrackAsset derived classes support the following attributes: HideInMenuAttribute TrackColorAttribute TrackClipTypeAttribute TrackBindingTypeAttribute DisplayNameAttribute

Examples

[TrackColor(1, 0, 0)]
[TrackBindingType(typeof(Animator))]
[TrackClipType(typeof(AnimationClip))]
public class CustomAnimationTrack : TrackAsset { }
