Changelog #

0.9.2 #

Bugfix #

  • handle more than 32 entities with the same components

0.9.1 #

Bugfix #

  • handle more than 32 components when adding systems for components that haven't been used yet

0.9.0 #

Internal #

  • updated dependenciesto stable versions

0.9.0-nullsafety.0 #

Breaking API Changes #

  • removed ComponentTypeManager and moved methods to ComponentType
  • getComponents* methods in ComponentManager now return a List instead of a Bag

Enhancements #

  • switched to NNBD mode
  • added OptionalMapper with a nullable return type for the [] operator

0.8.0 (Dart 2.0+ required) #

Breaking API Changes #

  • removed deprecated code
  • replaced Entity with int, methods previously on Entity need to be called on World, with the int value of the entity as the first parameter
  • removed world.processEntityChanges, it's now done by default after every system
  • Aspect no longer uses static methods, uses named constructors instead (migration: replace Aspect.getAspectF with Aspect.f)
  • methods in Aspect no longer return the aspect, use cascading operator to chain calls
  • improved type safety for world.getManager and world.getSystem, no longer takes a Type as parameter and uses generic methods instead (e.g. world.getManager<TagManager>() instead of world.getManager(TagManager))
  • removed Type parameter in the constructor of Mapper, change code from Mapper<Position>(Position, world) to Mapper<Position>(world)

Enhancements #

  • world.destroy() for cleaning up EntitySystems and Managers

Internal #

  • existing entities are processed first, addition of new entities is processed last, makes more sense now that the processing is done after every system

0.7.3 #

Bugfixes #

  • adding an entity to a dirty EntityBag could lead to an inconsistency between the bitset and the list of entities

0.7.2 #

Bugfixes #

  • removing an entity multiple times caused it to be added to the entity pool multiple times

0.7.1 #

Internal #

  • upgraded dependencies

0.7.0 #

Breaking API Changes #

  • renamed Poolable to Pooled
  • renamed ComponentPoolable to PooledComponent
  • removed FastMath and Utils, unrelated to ECS
  • removed removeAll from Bag
  • time and frame getters have been moved from World to EntitySystem, World has methods instead

API Changes #

  • deprecated ComponentMapper use Mapper instead
  • deprecated ComponentMapper#get(Entity), use Mapper[Entity] instead
  • properties have been added to the World, can be accessed using the [] operator
  • Systems can be assigned to a group when adding them to the World, Word.process() can be called for a specific group

Enhancements #

  • performance improvement when removing entities

Bugfixes #

  • DelayedEntityProcessingSystem keeps running until all current entities have expired

Internal #

  • upgraded dependencies

0.6.0 #

API Changes #

  • Bag is Iterable
  • removed ReadOnlyBag, when upgrading to 0.6.0 replace every occurence of ReadOnlyBag with Iterable

0.5.2 #

Enhancements #

  • injection works for Managers
  • initialize() in the Manager is no longer abstract (same as in EntitySystem)
  • World.createEntity got an optional paramter to create an Entity with components
  • new function World.createAndAddEntity which adds the Entity to the world after creation

Bugfixes #

  • added getter for the World in Manager
  • the uniqueId of an Entity was always 0, not very unique

0.5.1 #

Internal #

  • added version constraint for release of Dart

0.5.0 #

Enhancements #

  • more injection, less boilerplate (when using dartemis_mirrors)
    • Instances of ComponentMapper no longer need to be created in the initialize-method of a system, they will be injected
    • Managers and EntitySystems no longer need to be requested from the World in the initialize-method of a system, they will be injected

0.4.2 #

Bugfixes #

  • EntityManager.isEnabled() no longer fails if the bag of disabled entities is smaller than the id of the checked entity

Enhancements #

  • added getters for current time and frame to World

0.4.1 #

Bugfixes #

  • World.deleteAllEntites() did not work if there was already a deleted entity
  • writing to the Bag by index doesn't make it smaller anymore

0.4.0 #

API Changes #

  • swapped parameters of Tagmanager.register
  • replaced ImmutableBag with ReadOnlyBag, added getter for ReadOnlyBag to Bag
  • changed FreeComponents to ObjectPool
  • old Component has changed, there are two different kinds of components now:
    • instances of classes extending ComponentPoolable will be added to the ObjectPool when they are removed from an Entity (preventing garbage collection and allowing reuse)
    • instances of classes extending Component will not be added to the ObjectPool when they are removed from an Entity (allowing garbage collection)

Enhancements #

  • added function deleteAllEntities to World
  • IntervalEntitySystem has a getter for the delta since the systm was processed last
  • updated to work with Dart M4

Bugfixes #
