There have been quite a few things happening in Ashley during the past month, enough to call for a brand new release. Ashley 1.2.0 can now be fetched from Maven Central and this is what you'll find new.
- API addition: people requested to put
Entity#getComponent(Class)back in, so we accepted SgtCODFish‘s PR.ComponentMapperis still the most efficient and encouraged method to retrieve an entity's components. - API addition: added
PooledEngine#clearPools()to delete unused entity and component pool memory. - API addition: adds
EntitySystem#setProcessing(boolean)so as to be able to enable/disable systems at will. - API addition: adds
Engine#getSystems(). - API addition: you can now listen to entity events on a per family basis.
- Crash fix: things would blow up if you deleted entities from
IteratingSystem#processEntity(). - Bug fix: removing listeners while dispatching a
Signalwould make other listeners miss the event. Thanks to vlaaad for the PR! - 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.
- 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.
- Internals: small performance improvement.
- Others: added benchmark suite to compare Ashley's performance with Atermis'.
If you're using the nightly builds, please change your dependency to com.badlogicgames.ashley:ashley:1.2.1-SNAPSHOT. Both the wiki and the javadocs have been updated to reflect the latest changes.
Thanks to everyone using Ashley, opening issues and, of course, sending pull requests. I'm extremely pleased with the response, it's awesome to see how active things are.
Keep it up guys!
