artemis-odb-0.13.1

Change Log

Version: 0.13.1 - 2015-09-20

• Fix: Deleted entities no longer mess up subscriptions when edited in SubscriptionListener#removed.
• Fix: Deleted entities retain components.

artemis-odb-0.13.0

This release is a little peculiar, but handy:

• libgdx's json implementation now backs a second world serializer. This means saving/loading is now compatible when building with GWT, and more libgdx container classes are properly serialized.

• The new debug artifact, artemis-odb-debug injects some extra runtime checks compared to artemis-odb. Useful for tracking down escaping flyweight entities.

  artemis-odb-debug replaces artemis-odb, either use a profile or do it quick and dirty:

Change Log

Version: 0.13.0 - 2015-09-14

• BREAKING CHANGES
  • World#getEntity(int) can return inactive Entities, check state using Entity#isActive or
    EntitityManager.isActive(int).
  • Entity.isActive no longer works for checking whether an entity was just created, instead
    use EntityManager#isNew(int).
• New additional serialization backend: json via libgdx.
  • GWT support, works with libgdx's HTML5 backend.
  • Supports more libgdx classes out of the box.
• New artemis-odb-debug artifact
  • Replaces normal artemis-odb with this (remove artemis-odb from pom/gradle/IDE)
  • Performs extra runtime checks; tries to catch run-away flyweights.
  • Incurs a rather hefty performance penalty.
• Fix: SubscriptionListeners#removed ids resolved to a lot of nulls.

Version: 0.12.1 - 2015-09-05

• Fix: IntDeque resets beginIndex when growing.

artemis-odb-0.12.0

DON'T USE THIS VERSION, GO WITH 0.12.1 instead.

So... another feature release before hitting 1.0.0. This one is smaller than usual, which I suppose is a good thing.

Change Log

Version: 0.12.0 - 2015-09-04

• InvocationStrategy configurable via WorldConfiguration.
• Add @Skipwire annotation to exclude injection targets.
• Entities recycled in FIFO order.
• Change EntitySubscription order to deleted/added/changed.
• Change AspectSubscription order to removed/inserted.
• FIX: Resolved potential "markSupported() is undefined for the type InputStream" message when
  compiling for GWT.

Version: 0.11.4 - 2015-08-18

• Fix: Excessive object creation when serializing entities.
• Fix: Components referencing other entities are implicitly included when serializing.
• Fix: SaveFileFormat should only enumerate required components.

Version: 0.11.3 - 2015-08-14

• Fix: entity reference operations could fail when loading into a fresh World instance.

Version: 0.11.2 - 2015-08-11

• Added boolean WorldSerializationManager#alwaysLoadStreamMemory, forces fully loading the stream into
  memory during loading, even if stream reports that mark is supported. Necessary when working
  with libgdx's FileHandles.
  • Enabled by default.
• Fix: Duplicate ComponentNameComparator in json module, causing failing android builds.

Version: 0.11.1 - 2015-08-11

• Fix: Entities not registered as added to world during batch entity synchronization.

0.10.1 - a few steps closer to 1.0.0

Psst. 0.10.2 has been released - it fixes a bug w.r.t. entity transmuters.

0.10.0/0.10.1 dev suffered neglect during the past months. Saving/loading world instances has been pushed back to the next release. Earlier experiments waded in growing complexity. I have a much simpler solution in mind now, without sacrificing any/much of the potential of the previous design.

The biggest changes for this release revolve around the AspectSubscriptionManager, increasing the responsibility of WorldConfiguration, and generally decoupling the world - making it slightly more open to custom configurations.

Nota Bene: breaking existing code

This release can be considered a preparatory release anticipating 1.0.0. Some existing code will break; most/all deprecated code should have javadoc or exceptions pointing you in the right direction.

The cycle of breakage will stop once we reach 1.0.0; until then, please bear with me.

Nota Bene: perf hit

0.11.0 introduced a pretty nasty perf hit. Initial benchmarks indicate <25% poorer throughput when iterating entities.

In the interest of moving towards 1.0.0 as quickly as possible, optimizations restoring the performance has been postponed until 1.1.0 (or 1.0.0).

Change Log

Version: 0.10.1 - 2015-07-20

• Fix: Reduced visibility of AspectionSubscriptionManager constructor.
• Fix: NPE related to EntitySubscription#createSubscription.

Version: 0.10.0 - 2015-07-19

• MINOR BREAKING CHANGES
  • BaseSystem is now the most basic system type.
    • World#getSystems returns Bag.
  • EntitySystem constructor expects Aspect.Builder:
    • Implies existing classes have to be recompiled against this release.
    • Existing custom entity systems need to pass Aspect.Builder to EntitySystem.
  • EntitySystem no longer implements EntityObserver.
  • ArtemisProfiler#initialize now requires BaseSystem instead of EntitySystem.
  • VoidEntitySystem no longer subclass of EntitySystem.
  • setSystem and setManager now under WorldConfiguration. This
    effectively removes World#initialize, as initializations happens inside
    World's constructor.
• New internal EntitySubscription and accompanying AspectSubscriptionManager
  resulting in cleaner and more flexible EntitySystems.
• SystemInvocationStrategy opening up for more granular control over system processing.
  • Default strategy behaves as before.
• Aspect split into Aspect and Aspect.Builder.
  • Simplified static method names, mirroring Aspect's old instance methods.
• EntityFactories support for enum values.
• Children of EntitySystems can create flyweight entities.
• Fix: Uninitialized worlds threw cryptic NPE when invoking #process.
• Fix: World#createFactory(Class<EntityFactory>) was package local.
• Fix: Entity#edit used together with EntityTransmuters or Archetypes
  caused the wrong compositionId to be reported, if all changes took place
  during the same processing round..
