Database and Data Model for Star Wars: Legion.

Build Status

This package is written and maintained in Dart for maintainability. Future versions will have JSON-formatted build artifacts as well for use within other systems.

Star Wars, Star Wars: Legion and all related properties and text are owned by Fantasy Flight Games, Lucasfilm Ltd., and/or Disney.

Usage #

This package provides 2 libraries: catalog.dart and swlegion.dart. Library catalog is a (best effort) collection of all known cards and other models that may change over time. Common APIs include:

  • catalog.commands and Commands
  • catalog.units and Units
  • catalog.upgrades and Upgrades

Library swlegion.dart is just the data models, with the idea that they are used to create catalog.dart (and exported as catalog.json for use in non-Dart clients).

There is also a utility class Catalog (or the built-in instance, catalog) which adds the ability to do easy aggregations or compuations, for example which Upgrade(s) are valid given a Unit instance or reference, and a utility class Holodeck for running dice simulations and calculating statistics.

0.4.0 #

Large set of breaking changes and new content!

Catalog #

  • Renamed database.dart to catalog.dart. See the top-level field catalog.

Data Model #

  • Added surge_override (AttackSurge) field to Weapon.
  • Significant data model change for Keyword, now split into 3 new classes.
  • Changed the default serializers to always use standard JSON, fixed encoding issues that would cause issues with Firebase or other database formats that expect valid JSON. See lib/catalog.json for example output. Use the exported CustomJsonPlugin instead of StandardJsonPlugin.
  • Added ForceAlignment (instead of just Faction).

Holodeck #

  • Holodeck is now a utility class for executing simulations.
  • The existing database structure and reference lookups were moved to Catalog.

0.3.1 #

Database #

  • Added Chewbacca Operative Expansion.
  • Added Wookie Warriors Expansion.
  • Fixed the ID of Battle Meditation.
  • Added keywords to upgrades that provide them on active or passively.

Holodeck #

  • costOfUnit now treats upgrades as a @required named parameter.
  • Added totalMiniatures(unit, {Iterable<Reference<Upgrade>> upgrades}).

0.3.0 #

Data Model #

  • Corrects Upgrade to only compare based on .id.
  • Indexable.toRef is now optional, as an Indexable is also a Reference.

Database #

  • Normalized all enum IDs as lower-hyphenated-case.
  • Added .from to every enum, to use instead of valueOf.
  • Added .toString() to Reference to aid in debugging.
  • Added missing .isUnique = true for commanders/operatives.
  • Upgrade emergency stims now has a corrected ID of emergency-stims.
  • Created Commands, Units, Upgrades, Weapons classes for convenience:
import 'package:swlegion/database.dart';

void main() {
  print(Units.stormtroopers.points); // 44

Mechanics #

  • Added a new class, Holodeck, for game logic and helper functionality that is not strictly tied to the database nor to the serialized JSON model(s):
import 'package:swlegion/database.dart';
import 'package:swlegion/swlegion.dart';

void main() {
  // Can create a `Holodeck` using the provided data:
  final customDeck = Holodeck(
    commands: commands,
    units: units,
    upgrades: upgrades,

  // Or use the default `Holodeck` directly.

0.2.0 #

Data Model #

  • Moved Army and ArmyUnit out of this package.
  • CommandCard was added.
  • Replaced *Key instances with a single Reference<T> instance.
    • CommandCard, Unit, Upgrade all now implement Indexable<T>.
    • Upgrade's .restrictedToUnit is now a BuiltSet<Reference<Unit>>.

Database #

  • Added 'Emergency Stims' (Gear), which was accidentally omitted.
  • Fixed the cost of 'Estmeed Leader' (Command), which is 5 points not 10.
  • Fixed the ID of 'Esteemed Leader', which was mis-spelled.
  • Added CommandCard(s) for every existing commander and operative.

0.1.0 #

  • Initial stable release.
