AnimationPlayer#

Constructors#

Constructor#

new AnimationPlayer(model): AnimationPlayer

Parameters#

model#

PlayerModel

Returns#

AnimationPlayer

model#

readonly model: PlayerModel

onStateChange#

onStateChange: (() => void) | null = null

UI hook — fired whenever playing flips (including self-finish).

playing#

playing: boolean = false

Accessors#

hasAnimation#

Get Signature#

get hasAnimation(): boolean

Returns#

boolean

Methods#

seek()#

seek(time): void

Scrub to time seconds. Deterministic.

Parameters#

time#

number

Returns#

void

stop()#

stop(): void

Returns#

void

toggleAll()#

toggleAll(): void

Global Play button — every animated parameter on the shared clock.

Returns#

void

toggleParameters()#

toggleParameters(nodes): void

Interact-tool click — just the picked parameters, same shared clock.

Parameters#

nodes#

ParameterNode[]

Returns#

void

animatedParameters()#

animatedParameters(model): ParameterNode[]

Recursively collect animated parameters (header containers are display grouping).

Parameters#

model#

PlayerModel

Returns#

ParameterNode[]

animatedParametersFor()#

animatedParametersFor(model, nodeKey): ParameterNode[]

Interact-tool click resolution: the animated parameters referenced by any expression inside the subtree of the node keyed nodeKey — click the door, only the door's openAngle runs. A model with a single animated parameter resolves to it regardless of what was clicked.

Parameters#

model#

PlayerModel

nodeKey#

string

Returns#

ParameterNode[]

groupDuration()#

groupDuration(tracks): number

How long a GROUP of tracks runs — the longest member. One fold, not reimplemented at each call site: AnimationPlayer.run below uses it for whichever tracks are playing this tick, and a clip's length is this over its members (which is exactly why a clip stores no length of its own).

Parameters#

tracks#

Track[]

Returns#

number

trackDuration()#

trackDuration(track): number

Where a track's own domain ends — its last keyframe time. Not a stored field: the samples say it (see evaluate/animation.ts's header).

Parameters#

track#

Track

Returns#

number

trackValueAt()#

trackValueAt(track, time): number

Parameters#

track#

Track

time#

number

Returns#

number
