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.5 19/03/2021

1.0.0-nullsafety.3 19/03/2021

FIXED:

1.0.0-nullsafety.2 19/03/2021

CHANGES:

• Added a serializable component mixin.
