styx 2.2.0

An implementation of the ECS paradigm with an emphasis on simplicity.

[2.2.0] - 12/02/2022

CHANGES:

• Added a new match method to an EntityMatcher where you pass it an EntitySystem and it will return the list of filtered entities. Useful when a synchronous read of the matcher is required.

[2.1.0] - 04/02/2022

BREAKING CHANGES:

• Typing EntitySystem to allow for a custom entity key generator. Allows systems to uniquely identify Entities their own way if desired.

CHANGES:

• Deprecating the call methods as having extension methods for nullable and non-nullable generics had conflicts as one was not more specific than the other. It was mostly left for BC purposes but will be deprecated in 3.0.0.
• Added a new EntityUniqueKeyGeneratorFunction type and added a static factory method for systems if you require a custom key generator.

[2.0.1] - 31/01/2022

• Fixed issue with pub points.

[2.0.0] - 24/01/2022

BREAKING CHANGES:

• Replaced dependency on GetX and move to rxdart.
• EntitySystem now uses a BehvaiorSubject for entities.
• Moved back to using Entity directly instead of Rx<Entity>.
• The .styx extension has been removed and has been added to the styx_flutter:>=2.0 package.

[1.3.2] - 24/06/2021

FIXED:

• A bug where listening to the entity list would send two events, one with an empty list and one with the actual changed list. This was causing strange behavior for listeners.

[1.3.1] - 23/06/2021

FIXED:

• Extensions were not being exported and could not be used.

CHANGES:

• Added a styx extension for any Rx<T> type for ease of use for reactive widgets.

class Person {
  Person({String title = ''}) {
    this.title(title);
  }

  final title = ''.obs;
}

final person = Person(title: "Name");

/// Then inside a widget somewhere.
person.title.styx((value) {
  return Text(value);
})

[1.3.0] - 23/06/2021

BREAKING CHANGES:

• EntitySystem and EntityMatcher updated to expect Rx<Entity> instead of Entity directly as the Rx<T> functionality was expected in various places.

This will be changed in 2.0.0 as Entity itself will implement Rx directly and won't need to be wrapped with Rx<T>.

[1.2.1] - 22/06/2021

FIXED:

• guid was missing from Entity props, which could cause two different entities with matching components and values to match even though they have different guids.

[1.2.0] - 21/06/2021

CHANGES::

• Added a new EntityMatcher class that can be used to describe a way of matching entities. Can be used on it's own to create your own grouping of entities and will be used in the Flutter specific package for Styx.
• Added a new method hasComponent for when the Type is not explicity known.

[1.1.0] - 27/03/2021

Full release! Matched to Get ^4.1.0

CHANGES:

• Added a new method for getting component differences between two entities.

[1.0.0-nullsafety.6] - 19/03/2021

FIXED:

• Fixing an issue where the entityToJsonFunction was not being used.

[1.0.0-nullsafety.5] - 19/03/2021

FIXED:

• Fixing pub.dev warnings and gradings.

[1.0.0-nullsafety.4] - 19/03/2021

FIXED:

• Fixed an issue with a circular call between Entity and EntitySystem that was causing a StackOverflow error.

[1.0.0-nullsafety.3] - 19/03/2021

FIXED:

• Fixed an issue with json_serializable that was picking up on the fromJson factory on Entity.

[1.0.0-nullsafety.2] - 19/03/2021

CHANGES:

• Added a serializable component mixin.

[1.0.0-nullsafety.1] - 19/03/2021
