Intermact API Reference / @intermact/core / ReactiveEngine
Class: ReactiveEngine
Defined in: packages/core/src/reactive/engine.ts:39
Reactive runtime: tracks signals, derived object sources, and per-object updaters. Flushed each frame after the Player advances (design.md §8.4).
Constructors
Constructor
new ReactiveEngine():
ReactiveEngine
Returns
ReactiveEngine
Methods
addUpdater()
addUpdater(
targetId,fn): () =>void
Defined in: packages/core/src/reactive/engine.ts:114
Attach a per-frame updater to a registered object; returns an unsubscribe.
Parameters
targetId
string
fn
Returns
() => void
applySignalValue()
applySignalValue(
signalId,value):void
Defined in: packages/core/src/reactive/engine.ts:77
Apply a numeric value from a compiled signal track (seek-safe).
Parameters
signalId
value
number
Returns
void
dispose()
dispose():
void
Defined in: packages/core/src/reactive/engine.ts:104
Release all tracked signals, derived sources, and updaters.
Returns
void
flush()
flush(
scene,store,time):void
Defined in: packages/core/src/reactive/engine.ts:131
Run updaters and rebuild changed derived objects. Mutates the scene object map and bumps geometryVersion on affected runtime states.
Parameters
scene
store
time
number
Returns
void
inspect()
inspect():
ReactiveInspection
Defined in: packages/core/src/reactive/engine.ts:175
Read-only snapshot of the reactive graph for the Inspector (design.md §16): tracked signals, derived object sources (with their signal deps), and the per-object updater counts.
Returns
notifySignal()
notifySignal(
sig):void
Defined in: packages/core/src/reactive/engine.ts:165
Bump dependency versions when a signal changes (called from bindSignal).
Parameters
sig
ReadonlySignal<unknown>
Returns
void
registerDerived()
registerDerived(
id,source):void
Defined in: packages/core/src/reactive/engine.ts:83
Register a derived object source bound to a scene object id.
Parameters
id
string
source
Returns
void
registerSignal()
registerSignal<
T>(sig):void
Defined in: packages/core/src/reactive/engine.ts:50
Register a signal for tweenSignal timeline tracks.
Type Parameters
T
T
Parameters
sig
Signal<T>
Returns
void
resetSignalsToInitial()
resetSignalsToInitial():
void
Defined in: packages/core/src/reactive/engine.ts:58
Restore every tracked signal to its value at first registration (seek baseline).
Returns
void
serializeInitialSignals()
serializeInitialSignals():
Record<number,unknown>
Defined in: packages/core/src/reactive/engine.ts:70
Baseline signal values captured at first registration, keyed by numeric signal id (design.md §17 serialization). These are the values to persist so a deserialized project restores the same starting state.
Returns
Record<number, unknown>
unregisterObject()
unregisterObject(
targetId):void
Defined in: packages/core/src/reactive/engine.ts:97
Remove derived/updater state for a freed scene object.
Parameters
targetId
string
Returns
void
