dentity: ^1.5.0 copied to clipboard
wearemobilefirst.comA powerful and flexible Entity-Component-System (ECS) framework for Dart application.
1.0.0 #
- Initial version.
1.1.0 #
- Change the serialiser to use a map of components instead of a list.
1.1.1 #
- Add the entity serialiser json.
1.1.2 #
- Add component deserialisation method to entity serialiser.
1.1.3 #
- Add system get method to world.
1.2.0 #
- expose the component serialiser to the world.
- remove the need to pass the entity manager to the component serialiser.
1.2.1 #
- Fix entity deletion queue processing to prevent entities from being processed after deletion.
- Entity deletion queue is now processed after each system runs, ensuring proper entity lifecycle management.
- Add comprehensive entity deletion tests covering edge cases like cascading deletions and multi-system interactions.
1.4.0 #
- Add comprehensive stats collection system for profiling and debugging
- Optional stats tracking via
enableStats: trueflag in World constructor - Entity lifecycle tracking (created, destroyed, recycled, peak count)
- Queue size monitoring (creation and deletion queues)
- System performance profiling with timing measurements
- Archetype distribution tracking
- Snapshot and diff capabilities for comparing stats over time
- Reset functionality for clearing stats
- Optional stats tracking via
- Add industry-standard benchmark metrics
- ns/op (nanoseconds per operation) - Google Benchmark standard
- ops/s (operations per second) - throughput metric
- entities/s (entities per second) - entity-specific throughput
- ns/entity (cost per entity) - performance cost metric
- Add shared benchmark library for consistent testing
- Standardized entity counts: 1,024 (small), 16,384 (medium), 65,536 (large), 1,000,000 (very large)
- Reusable benchmark functions: creation, processing, removal, recycling, mixed workload
- Stats overhead measurement with accurate percentage calculation
- Enhanced benchmark Flutter app with professional UI
- Real-time progress tracking with progress bar
- Three chart types: Duration, Throughput, Stats Overhead comparison
- Expandable cards showing detailed metrics for each benchmark
- Dark theme with color-coded visualizations
- Industry-standard metric display (ops/s, ns/op, entities/s)
- All stats collection has minimal overhead (~24-32%) and zero overhead when disabled
1.3.0 #
- Add entity creation queue to prevent newly created entities from being processed by subsequent systems in the same frame.
- Entity creation queue is processed at the start of each world.process() call.
- Add comprehensive entity creation tests covering spawning, recycling, and multi-system interactions.
- Entities created during system processing are now deferred until the next frame for consistent behavior.
1.4.1 #
- Add world time tracking to WorldStats
- WorldStats now tracks accumulated world time using Duration type
- World time is displayed in stats output and snapshots
- World time is properly reset when stats are reset
1.5.0 #
- Add global world time and frame count tracking to World class
- World now tracks worldTime and frameCount as first-class properties
- Accessible via world.worldTime and world.frameCount
- Stats mirror these values as single source of truth
- Add world reference to System class
- Systems can now access their world via system.world
- New attachToWorld method replaces deprecated attach method
- Systems have direct access to world time and frame count
- Old attach method is deprecated but still functional for backwards compatibility
