scene_dash_v2_core 0.6.1

Headless ECS runtime for gameplay code: sparse-set stores, generational entities, events, clocks, command buffers, and a TestGame harness.

Changelog

0.6.1

• minor perf upgrades

0.6.0

• Stores create themselves on first use: spawning, add<T>, any type argument. registerTag and registerComponent are gone.
• Typed filters: .having<T>() / .without<T>() on query views and world.entitiesWith<T>(). The require:/exclude: Type lists are gone.
• .records is gone; use snapshot().
• emit<E> delivers to the event's own class channel when one exists, otherwise to the channel of E, so emit<GameEvent>(EnemyKilled()) reaches events<GameEvent>() readers instead of throwing, and emit(c ? A() : B()) still reaches events<A>() / events<B>().
• world.add is generic and creates the store of its static type when that is the component's exact type.
• get, tryGet and has see components no query has named yet, and read subtypes from their supertype's store without splitting it.
• Waiting spawn parts are claimed when their store is created, never during a running query and never through observers.
• A part with no exact store goes straight into a registered supertype store.
• spawn and add assert against Type, function, Future and Iterable parts (spawn([Enemy]), Enemy.new, nested lists).
• Despawn visits only the entity's stores once a world has more than 10, so its cost no longer grows with the number of component types.
• Add QueryView.revision, World.ensureStore<T>(), World.ensureEventChannel, store change listeners (addChangeListener/removeChangeListener), StoreRegistry.onCreated, lookup, count, storeAt and StoreMembership.
• SpawnQueue.ensureStore and world.entitiesWith(require:) are gone.

0.5.4

• Add QueryView1.get(entity): the component when the entity matches the query, or null.

0.5.3

• Fix a command flush replaying applied commands (or throwing RangeError) when an observer runs a schedule mid-flush. A nested Commands.apply now returns and the outer flush drains the queue.
• Fix world.remove<T> asserting when the entity was despawned earlier in the same flush.
• Fix Routine settling the whole plan when an empty child Sequence or Select is entered; it now reports to its parent like any other child.
• Allow a chain of exactly App.maxStateTransitionPasses transitions.
• World.reset now clears pending removeAfter deadlines.
• Store removeAfter generations unsigned, matching entity generations.
• Guard despawn against stores registered by observers mid-despawn.
• Skip query type bookkeeping in release builds; empty events<T>() reads no longer allocate.
• Assert a positive duration when resetting a repeating GameTimer.
• Remove unused World.debugEventChannels, EventChannelMaintenance.readerLagged and StateMachine.stateType.
• Point error messages at configureEvent<T>() and drop references to the removed @Resource() injection.

0.5.2

• Cache parked-component scans until new parts arrive; explicit component registration claims waiting parts, and despawn/reset release unclaimed parts.
• Use weak identity tracking for disposed resources. Shutdown attempts all cleanup callbacks and resources, then reports a CleanupException containing the original exceptions and stack traces.
• Make consumeAny use a constant-time cursor advance without a result list.
• Add EventReader.dispose() and release system readers on shutdown.
• Add snapshot() to query views; .records remains an eager allocating alias.
• Resolve function-based system ordering at boot, allowing references to later features. Validate missing and cross-schedule references, including independentOf when conflict detection is disabled.
• Check local documentation links and compile runnable Markdown examples in CI.
