public readonly record struct MotionContext

Everything a motion needs to know about the moment it is being evaluated at.

No guide page documents this yet — the page shows what the code says about itself.

Remarks

Time is normalised, not seconds. That is what makes a blend tree work: a walk of 1.2 s and a run of 0.8 s blended half and half have to put both feet down together, which they only do if both are sampled at the same fraction of their own cycle. The tree's own length is the weighted average of its children's, so a character speeding up from a walk to a run has its stride rate move continuously rather than jumping when the dominant clip changes.

Fields and properties (11)

public AnimationParameters Parameters
The values blend trees read.
public PoseScratch Scratch
Where a blend gets its temporary poses.
public float NormalizedTime
Where playback is, in [0, 1] across the motion's length.
public float PreviousNormalizedTime
Where it was last frame, for events and root motion.
public int Loops
How many whole passes were crossed since then.
public bool WantsRootMotion
Whether the return value will be used.
public AnimationEventBuffer? Events
Where events go, or to fire none.
public int Layer
Which layer to attribute events to.
public string State
Which state to attribute events to.
public float Weight
How much this motion is contributing overall, for event filtering.
public ConstraintTagBuffer? Constraints
Where a clip's live constraint tags go, or to report none.
