AuthoringContext

Remarks

The sequencer's second job. Assisted authoring measures proximity between the subject's effectors and the things around it, and a clip on its own carries none of that: which actors were in the scene, where they were, and what was in whose hand. This reads a .vxseq and answers those three questions at a moment.

⚠ It is discarded, and that is the design rather than a limitation. What comes out of the proposal pass is a surface coordinate that resolves from the live game alone. The scene exists so the editor can work out what the animator meant; a constraint that needed it at runtime would be a bug, and AnimationClipAsset.ToContent drops the reference for exactly that reason.

⚠ A prop becomes a proxy shape on the subject's rig, and there is nowhere else to put it. ConstraintProposals measures against a ProxyShapeSet, whose shapes hang off joints — so a prop lying on a table is a shape on the subject's root with a world-space offset, and a prop in the subject's hand is a shape on that hand's joint. Both are true statements about where the thing was, which is all the proximity pass needs.

Fields and properties (4)

• public SequenceAsset Sequence

  The scene.

• public SequenceTrackData? Subject

  The track the clip being marked up belongs to, or .

• public IReadOnlyList<SequenceTrackData> Others

  Every other transform track, which is what the subject might be touching.

• public bool IsUsable

  Whether the scene says enough to be worth measuring against.

Methods (4)

• public static AuthoringContext From(SequenceAsset sequence)

  Reads a sequence as an authoring context.

• public IReadOnlyList<AuthoringActor> At(float time)

  Who was where, and what the subject was holding, at a moment.

• public BoneTransform SubjectAt(float time)

  The subject's own place at a moment.

• public ProxyShapeSet Augment(ProxyShapeSet body, Skeleton rig, float time, float size = 0.08)

  The subject's shapes plus one for every other actor, placed where the scene says it was.
