AnimationController

Defined in: renderer/src/AnimationController.ts:53

High-level animation controller that manages named animations on top of a sibling AnimatedSpriteComponent.

Provides one-shot locking, per-animation anchors, and type-safe animation names via the generic parameter.

Properties

enabled

enabled: boolean

Component.enabled

entity

entity: Entity

Defined in: core/dist/index.d.ts:540

Back-reference to the owning entity. Set by the engine when the component is added to an entity. Do not set manually.

Component.entity

Accessors

context

Get Signature

get context(): EngineContext

Defined in: core/dist/index.d.ts:554

Access the EngineContext from the entity’s scene. Throws if the entity is not in a scene.

Returns

EngineContext

Inherited from

Component.context

current

Get Signature

get current(): "" | T

Defined in: renderer/src/AnimationController.ts:102

Currently playing animation name, or "" if none.

frame

Get Signature

Defined in: renderer/src/AnimationController.ts:112

Current frame index of the underlying AnimatedSprite.

Returns

number

locked

Get Signature

get locked(): boolean

Defined in: renderer/src/AnimationController.ts:107

True if a one-shot animation is blocking.

Returns

boolean

scene

Get Signature

get scene(): Scene

Defined in: core/dist/index.d.ts:549

Access the entity’s scene. Throws if the entity is not in a scene. Prefer this over this.entity.scene! in component methods.

Returns

Scene

Inherited from

Component.scene

speed

Get Signature

get speed(): number

Defined in: renderer/src/AnimationController.ts:117

Runtime speed multiplier (default 1).

Returns

number

Set Signature

set speed(value): void

Defined in: renderer/src/AnimationController.ts:121

Parameters

value

number

Returns

void

Methods

_runCleanups()

_runCleanups(): void

Defined in: core/dist/index.d.ts:584

Internal

Run and clear all registered cleanups. Called by Entity.remove() and Entity._performDestroy() before onRemove/onDestroy.

Returns

void

Inherited from

Component._runCleanups

addCleanup()

protected addCleanup(fn): void

Defined in: core/dist/index.d.ts:578

Parameters

fn

() => void

Returns

void

Inherited from

Component.addCleanup

afterRestore()?

optional afterRestore(data, resolve): void

Defined in: core/dist/index.d.ts:598

Called after onAdd() during save/load restoration. Apply state that depends on onAdd() having run.

Parameters

data

unknown

resolve

SnapshotResolver

Returns

void

Inherited from

Component.afterRestore

calcDuration()

calcDuration(name): number

Defined in: renderer/src/AnimationController.ts:167

Calculate the wall-clock duration (ms) of a named animation.

Frame-rate independent: PixiJS normalises deltaTime via Ticker.targetFPMS (0.06), so the formula holds at any actual fps. Inaccurate only if Ticker.shared.speed is changed from 1.

Parameters

name

T

Returns

number

fixedUpdate()?

optional fixedUpdate(dt): void

Defined in: core/dist/index.d.ts:594

Called every fixed timestep by the built-in ComponentUpdateSystem.

Parameters

dt

number

Returns

void

Inherited from

Component.fixedUpdate

forcePlay()

forcePlay(name): void

Defined in: renderer/src/AnimationController.ts:147

Clear lock and force-switch to the given animation.

Parameters

name

T

Returns

void

inFrameRange()

inFrameRange(start, end): boolean

Defined in: renderer/src/AnimationController.ts:173

Check whether the current frame is within [start, end] inclusive.

Parameters

start

number

end

number

Returns

boolean

listen()

protected listen<T>(entity, token, handler): void

Defined in: core/dist/index.d.ts:574
