Latest Changes 0.5

  • Deployed to Maven Central!
  • Gradle build added
  • Few bugs fixed: #32, #33, #40
  • java.util.BitSet replaced by libgdx Bits

Version 0.4

  • Deprecated DelayedEntityProcessingSystem.
  • Fixed some bugs and added pooling to GroupManager + unit tests.
  • Fixed a bug in ComponentManager that was causing NPE's when a component was removed from an entity.
  • Fixed an entity removal bug which was causing NPE's.
  • Used JProfiler to identify a few CPU intensive hotspots and made performance improving changes.
  • Created GenericGroupManager.
  • Deprecated Aspect in favor of Filter. (better clarity of purpose)
  • PlayerManager and TeamManager have been cleaned up.
  • TagManager is deprecated in favor or SingletonEntityManager.
  • Added SkipEntityProcessingSystem to replace DelayedEntityProcessingSystem. Added ExpirationEntitySystem.
  • Cleaning up Event System. Constraining World to only one Event System. Removed some unused classes, added classes for handling events.

Version 0.3

  • Adding the ability to dispose of the world.
  • For better support of GWT and HTML5 games with libgdx, removed automatic ComponentMapper initialization. ComponentMappers should be initialized manually in EntitySystem.initialize() method by calling mapper = world.getMapper(Component.class).
  • Changed the libgdx dependency to 0.9.9 instead of the nightly build.
  • Changed the EventSystem.getEvents() to take an Array instead of an ObjectSet to preserve the order of the events occuring.
  • Added a SingletonComponentManager to manage singleton components in the world.
  • Bug fix in DelayedEntityProcessingSystem.

Version 0.2

  • Created an event system to allow inter-system communication.
  • Speed improvement: Removed some unnecessary accessor calls.
  • Deprecated Mapper annotation and imporved ComoponentMapper intialization
  • Allow inheritance for EntitySystems (component mappers are initialized in parent objects as well)
  • Fixed a bug in EntitySystem.check(e) and made it more performant.
  • Adding ComponentMapper reuse. No need to create new instances for all the systems.
  • Adding @IgnoreMapper annotation to allow bypassing ComponentMapper initialization during world initialization. (useful for generic systems with generic mappers, where reflection won't work)
  • Adding a notion of stopping event propagation by marking event handled.
  • Making a dent in unit testing.

Version 0.1

  • Some files have been reshuffled in the packages for better organization.
  • Most private fields and methods have been changed to protected to allow for easier extension.
  • Component is now an interface.
  • ComponentType has been removed. The indexing done in the ComponentManager.
  • Bag and ImmutableBag have been removed, in favor of a slightly modified com.badlogic.gdx.utils.Array.
  • HashMaps have been replaced by com.badlogic.gdx.utils.ObjectMap. ObjectIntMap and IntArray are used where appropriate.
  • Starting to add more Javadoc to classes.
  • No more classes instantiated every time World.process is run.
  • IdentifierPool has been moved to a separate class.
  • Removed all the unused utils classes.
  • Added a check to EntitySystem to prune activeEntities before processing. (in case of removal by a different system earlier on in the process cycle)
  • Cleaned up some compiler warnings.
  • Mavenize the project
