CameraFollow

Defined in: renderer/src/CameraFollow.ts:11

Camera follow behavior. Smoothly moves CameraComponent.position toward a target each frame. Add order matters: runs before CameraBoundsComponent so bounds clamping happens after follow.

new CameraFollow(): CameraFollow

Component.constructor

enabled: boolean

Defined in: core/dist/index.d.ts:647

Whether this component is active. Disabled components are skipped by ComponentUpdateSystem.

Component.enabled


entity: Entity

Defined in: core/dist/index.d.ts:645

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

Component.entity

get context(): EngineContext

Defined in: core/dist/index.d.ts:660

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

EngineContext

Component.context


get scene(): Scene

Defined in: core/dist/index.d.ts:655

Access the entity’s scene. Throws if the entity is not in a scene. Prefer this over threading through this.entity.scene in component code.

Scene

Component.scene

_runCleanups(): void

Defined in: core/dist/index.d.ts:697

Internal

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

void

Component._runCleanups


protected addCleanup(fn): void

Defined in: core/dist/index.d.ts:691

Register a cleanup function to run when this component is removed or destroyed.

() => void

void

Component.addCleanup


optional afterRestore(data, resolve): void

Defined in: core/dist/index.d.ts:711

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

optional fixedUpdate(dt): void

Defined in: core/dist/index.d.ts:707

Called every fixed timestep by the built-in ComponentUpdateSystem.

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

Defined in: core/dist/index.d.ts:687

Subscribe to events on any entity, auto-unsubscribe on removal.

protected listenScene<T>(token, handler): void

Defined in: core/dist/index.d.ts:689

Subscribe to scene-level bubbled events, auto-unsubscribe on removal.

T

optional onAdd(): void

Defined in: core/dist/index.d.ts:699

Called when the component is added to an entity.

void

Component.onAdd


optional onDestroy(): void

Defined in: core/dist/index.d.ts:703

Called when the component is destroyed (entity destroyed or component removed).

void

Component.onDestroy


optional onRemove(): void

Defined in: core/dist/index.d.ts:701

Called when the component is removed from an entity.

void

Component.onRemove


optional serialize(): unknown

Defined in: core/dist/index.d.ts:709

Return a JSON-serializable snapshot of this component’s state. Used by the save system.

unknown

Component.serialize


protected service<T>(key): T

Defined in: core/dist/index.d.ts:677

Lazy proxy-based service resolution. Can be used at field-declaration time:

readonly input = this.service(InputManagerKey);

The actual resolution is deferred until first property access.

T extends object

Component.service


protected sibling<C>(cls): C

Defined in: core/dist/index.d.ts:685

Lazy proxy-based sibling component resolution. Can be used at field-declaration time:

readonly anim = this.sibling(AnimatedSpriteComponent);

The actual resolution is deferred until first property access.

C extends Component

start(target, options?): void

Defined in: renderer/src/CameraFollow.ts:19

Start following a target.

stop(): void

Defined in: renderer/src/CameraFollow.ts:32

Stop following any target.

update(dt): void

Defined in: renderer/src/CameraFollow.ts:37

Called every frame by the built-in ComponentUpdateSystem.

number

void

Component.update


protected use<T>(key): T

Defined in: core/dist/index.d.ts:668

Resolve a service by key, cached after first lookup. Scene-scoped values (registered via scene._registerScoped) take precedence over engine scope. A key declared with scope: "scene" that falls back to engine scope emits a one-shot dev warning — almost always signals a missed beforeEnter hook.
