Add `typecheck` script to package.json, expand tsconfig include
paths to cover tests and examples, and update serialization tests
to correctly resolve player IDs from relationship edges.
Introduce the ability to attach optional data payloads to
relationships. This includes:
- Updating `defineRelationship` to accept default values.
- Adding `getRelData` and `setRelData` to the `World` class.
- Allowing `relate` to accept an optional data override.
- Updating serialization to include relationship data in snapshots.
- Implementing lazy storage for relationship data using `SparseSet`.
Convert `getRelatedTo` from returning an array to returning an
`IterableIterator`. This improves memory efficiency by yielding
entities lazily instead of allocating a new array on every call.
Introduces a `TaskRunner` for executing behavior trees within the
ECS world. Supports leaf, sequential, parallel, and random task
kinds, along with status propagation (succeeded, failed, cancelled).
Introduces a `CommandQueue` to handle command components. It allows
registering handlers that are executed when `execute()` is called,
automatically removing the command component and cleaning up empty
entities. Includes an interruption mechanism to pause processing
during asynchronous operations.
Replace `any` types with specific interfaces like `WorldEvent`,
`QueryUpdate`, and `Entity` to strengthen type checking. This includes
refining the deserialization logic in `World.fromSnapshot` to use
properly typed component definitions.
Introduce `toJSON` and `fromJSON` methods to the `World` class to
allow saving and restoring world states. This requires components and
relationships to have human-readable names for stable serialization.
Initial implementation of an Entity-Component-System (ECS) featuring:
- Sparse set-based component storage for efficient access.
- Entity lifecycle management with generation-based recycling.
- Reactive query system using RxJS for change tracking.
- Batched event flushing to support frame-based updates.
- Type-safe component definitions via TypeScript inference.
