Ashley 1.7.0

  • API change: removed UUIDs from entities, users should implement their own ID system when needed. This helps with networked games. Issue #182.

  • API consistency: defines what happens when an Entity is added twice to an Engine and when we try do nested updates. We throw an exception in both cases. Issue #173.
  • API consistency: adding an EntitySystem of the same class twice replaces the previous one, just like it has always happened when adding Components to an Entity. Commit 1dbfcb4dc1ea0ea0a0fdb0d481c00b7dd9b8dd8f.
  • Update: uses Libgdx 1.6.4. Commit 0284510e759c7d97c7d1e7acaf7d29d6071434cc.

Ashley 1.5.0

  • API addition: adds getFamily() method to IntervalIteratingSystem and IteratingSystem. Commit 55241f5256c0ec186992262c7d598811bc4664fe.
  • API change: IntervalSystem's update() method is now final, as it doesn't make sense to override it. Commit bffa44cd5a59ca156e63b2ce7919869e41538907.

  • Bug fix: empty Family now matches empty entities. Commit db1286f69c22a5bb4b9e7055d8f65d3063824a9b.

Ashley 1.4.0

  • API deprecation: finally removed the Family.getFor() methods. In order to retrieve a family, you can do Family.all().one().exclude().get(). Commit d6222d9ee0cca6f06dd61b04bae6d092497425a5.
  • API change: makes family Builder package protected. Issue #137.
  • Bug fix: EntityOperation and ComponentOperation are now properly reset when put back into their pools. This doesn't affect the API at all and it's an implementation detail fix. Commit 356cf4097f7c870cccc67cffca62ff3f32f103da.

  • API addition: added getEntities() method to Engine, which returns an immutable array of all the entities registered with said engine. Commit ed3d3b7ef040023c8bd4d64efb6e9fcad69dc9aa.
  • Bug fix: remove old component when adding a new one of the same type to an entity. Commit 3910be7b4ae472f415c22c0f5109e4f140056f7d.
  • Bug fix: fixes component not being added to an entity when done from an entityRemoved() family entity listener handler. Commit 9f6aa51229544f9a66c12f7f7fdcff7e6bf5dbde.

Ashley 1.3.2

  • API: we now use a builder pattern to create Family objects. More about it on the wiki. Commit addition974f12f6d53c5d92992ddd6bf09edd44937d9e66.
  • API addition: new SortedIteratingSystem by Lusito. Commit 905b26895536c57d9d42d994e62237c60f909e0c.

  • Bug fixes: fixes freeze when calling removeAllEntities(). Issue #101.
  • Improvement: we made a bunch of changes that increase performance.

Ashley 1.3.1

Bug fix: fixed IllegalArgumentException thrown when trying to remove components from an already reset entity. The call has no effect now. Thanks for that SgtCoDFish. Issue #77. Bug fix: fixed family match failure due to silly silly hashing. Issue #78. Bug fix: fixed entity.getId() always returning 0 for recycled pooled entities. Issue #82. Bug fix: fixed nested iteration problem caused by adding/removing entities from an entity added/removed listener handler. Issue #81. Bug fix: fixed missing type error in GWT when using PooledEngine. GWT should be quite smooth now. Commit cb3347239504972b86653efab8d9051ec5366760.

Ashley 1.3.0

  • API addition: adds IntervalSystem and IntervalIteratingSystem, which are updated at a fixed interval. Commit 47bf907b15ad8ed4297a10eb6b6b311e1542dcb8.
  • API addition: adds getEntities() to IteratingSystem and IntervalIteratingSystem. Commit f1ccdbea63a175f2a76c26b46661998b6a131c59.
  • API change: entities use long as ID. Changes entity.getIndex() for entity.getId(). Ids are reset to 0 after the entity is removed from the engine. Commit 6f9d2b78c34f72d03e76d40c8d9704f1c763e59a.
  • Bug fix: we finally got rid of the issues related to deleting entities and adding/removing components mid system processing. Commit a2a63f4e42e09e3221331b2333e675b3a4ab6fe3.
  • Bug fix: fixes problem with removing pooled entities. #64.
  • Bug fix: fixes pooled entities not being fully reset. Issue #72.
  • Bug fix: fixes broken GWT compatibility. Commit 9a01938713946cad0c31d21ecb723443ccf6b2ff.

Ashley 1.2.0

  • API addition: people requested to put Entity#getComponent(Class) back in, so we accepted SgtCODFish's PR. ComponentMapper is still the most efficient and encouraged method to retrieve an entity's components. Issue #51.
  • API addition: added PooledEngine#clearPools() to delete unused entity and component pool memory. Commit 28372993d60d6e2f460f36e27df953936e550933.
  • API addition: adds EntitySystem#setProcessing(boolean) so as to be able to enable/disable systems at will. Commit 188239aeaa3e99c9bd7ebab268a9e9959d2a09c2.
  • API addition: adds Engine#getSystems(). Commit 8f54a2a5ee97c87cba57bd187b4aeb2aef7ec831.
  • API addition: you can now listen to entity events on a per family basis. Commit f90d12932bd958061eb0ad33b925cf6457880c46.
  • Crash fix: things would blow up if you deleted entities from IteratingSystem#processEntity(). Commit d5ace4e43a32c27fec82821b90b3e55c89ad373f.
  • Bug fix: removing listeners while dispatching a Signal would make other listeners miss the event. Thanks to vlaaad for the PR! Issue #52.
  • Bug fix: some entities were skipped if the user removed an entity from the engine mid system update. Removing an entity from a system by changing its components mid iteration also caused problems, which are now solved. Issue #44.
  • Bug fix: there was a problem with family membership not being properly updated when removing a component from an entity was supposed to result in said entity being added to the family. This only affected families that exclude components. Issue #56.
  • Internals: small performance improvement. Issue #59.
  • Others: added benchmark suite to compare Ashley's performance with Atermis'. Commit d6fec987e1ce493c559a7e8fdea7fc8f6cd82d7b.

Ashley 1.1.0

  • Performance improvements: massive performance gains with O(1) component retrieval through ComponentMapper and the use of Array<Entity> rather than IntMap<Entity>. Unfortunately this changes the API slightly, but hopefully you guys will appreciate the benefits. Commit 8c98e9799bb6cc65cf61669eed36d7f8f04a2da4.
  • Complete Ashley manual: now the wiki has a lot more content, it fully covers Ashley. The rest is sugar.
  • API Cleanup: renames Family.getFamilyFor() to Family.getFor() for simplicity. Commit 3182782dfd71e13f0bf1c03490512d91921117a3.
  • Configurable pools: PooledEngine now accepts the initial and maximum sizes for the entity and components pools. This will add a lot more flexibility to bigger games. Commit 569f089f9236dc8c2da09f4fe3b4d33880745d8a.
  • Libgdx 1.3.0: Ashley now depends on gdx-core 1.3.0. Commit aa97ecbf8344ea6de5afeb608ac65ccd12e80965.

Ashley 1.0.1

  • Gradle: we got rid of the Eclipse projects and now use Gradle to manage our dependencies and build process. Commit 3cd93f2c17fd65470a60dfa2af7d84c2ee7e7865.
  • Maven Central: Ashley is now available from Maven Central, which makes it dead easy for your project to depend on it. In Gradle, add the following dependency: compile "com.badlogicgames.ashley:ashley:1.0.1".
  • Jenkins build: Mario kindly offered us some server time to make sure Ashley is always stable. *** Unit tests**: there are unit tests for pretty much every component in Ashley. They are run after every commit by our Jenkins job.
  • Immutable collections: core Ashley classes now return ImmutableArray and ImmutableIntMap references, making it harder for client code to break the system.
  • Family filtering: now we get the collection of entities that have a set of components, have at least one component from a given set and do not have a single component from another given set. Commit 9492d14a3e5cf4ad0d87305f8f7bb298bb8d687a.
  • GWT compatibility: you can now use Ashley for HTML5 games through the magic of GWT and Libgdx.
  • Depends on gdx core: this has allowed us to remove all the duplicated optimised container classes and gives us a GWT compatible reflection API. Some might say it's a big dependency but we do believe the pros outweigh the cons. Commit 81d9a2e5f38df186f4b147b82ede274c950795b6.
  • Cleanup and bug fixes.
