Methods

reset()

reset(_target): void

Defined in: libs/scene/src/animation/animationtrack.ts:98

Reset the track to its initial state for the given target.

Intended to stop playback and rewind the target to the first frame or default state.

Parameters

_target

object

The animated object to reset.

Returns

void

Inherited from

AnimationTrack.reset

---

clone()

clone(): this

Defined in: libs/scene/src/animation/scaletrack.ts:67

Clone this animation track

Returns

this

Overrides

AnimationTrack.clone

---

calculateState()

calculateState(target, currentTime): Vector3

Defined in: libs/scene/src/animation/scaletrack.ts:71

Compute the animation state at the specified time.

Implementations should be pure with respect to inputs: given the same target and currentTime, return the same StateType.

Parameters

target

object

The animated object (used to resolve current baseline if needed).

currentTime

number

Time cursor in seconds within the track's timeline.

Returns

Vector3

The computed state at currentTime.

Overrides

AnimationTrack.calculateState

---

applyState()

applyState(node, state): void

Defined in: libs/scene/src/animation/scaletrack.ts:76

Apply a previously computed animation state to the target.

Parameters

node

SceneNode

The animated object to modify.

state

Vector3

The state to apply.

Returns

void

Overrides

AnimationTrack.applyState

---

mixState()

mixState(a, b, t): Vector3

Defined in: libs/scene/src/animation/scaletrack.ts:80

Blend two states into a new state using a weight.

Parameters

a

Vector3

First state.

b

Vector3

Second state.

t

number

Blend weight in [0, 1], where 0 yields a and 1 yields b.

Returns

Vector3

The blended state.

Overrides

AnimationTrack.mixState

---

getBlendId()

getBlendId(): string

Defined in: libs/scene/src/animation/scaletrack.ts:84

Get the blend identifier for this track.

Tracks with the same blend ID are considered compatible for blending on the same target channel/property.

Returns

string

An identifier used to group compatible tracks for blending.

Overrides

AnimationTrack.getBlendId

---

getDuration()

getDuration(): number

Defined in: libs/scene/src/animation/scaletrack.ts:88

Get the intrinsic duration of this track in seconds.

Used by clips to determine overall clip duration and looping behavior.

Returns

number

Track duration (seconds).

Overrides

AnimationTrack.getDuration
