cellular_automata 1.0.2

A library and platform for playing and experimenting with cellular automata.

Changelog

1.0

• Web renderers have been moved into a new package: cellular_automata_web. This core package can now be loaded into none web enviroments such as flutter etc.
• example/ folder now contains numerous ascii based examples that can be run from command-line
• Player renamed Scene
• Simulator renamed Automaton
• onRender renamed onPaint
• SimulationCompleteReason renamed SceneCompleteReason
• onPaintFull now available which will paint a full scene every generation. Note: This is a not as performant as onPaint which will only paints the changes in a scene
• AsciiRenderer added. This is a very simple text based renderer, used in the examples.
• onPrepare fired before scene starts running. This is when a generator could be used to seed the automaton.
• Now supports multiple automata running in a single scene. used addAutomaton() to add automata.
• Recased all enums to camel case.

0.9

• Dart 2.0. Tested and all works correctly.
• Enabled Travis CI: https://travis-ci.org/jimmyff/cellular_automata/

0.8

• MCellGenerations rule parser added. This can parse all MCell Generations configs.
• Credits
• onStable renamed onComplete, now passes SimulatorCompleteReason enum value. Current states are: duration and stable
• Demos updated to include MCell
• Credits file created to credit those that wrote/discovered the rules
• Decent Refactor, reorganised stuff!
  • Simulator renamed Player
  • Array2D replaced with CellGrid which combines Array2D with CA specific functionality which simplifies CellWorld.
  • CARules interface updated
  • CellWorld renamed Simulator

0.7

• Optimised MajorityVote Rules, utilises edge detection to determine activity
• Added paintFullSize option to CanvasRenderer: This allows the scene to be painted at actual size rather than small and then resized via CSS.
• Added maxAge as a Simulator constructor parameter, if this is set then onStable is called when the generation count surpasses maxAge
• Added package:logging so debug information can be enabled / disabled
• Updated demos

0.6

• Stable simulation detection. This broadcast to the onStable stream after detecting repeating identical generations or repeating generation activeCellCount patterns spanning up to 8 generations.
• Demos updated to auto reset on stable scene (excluding rendering examples)

0.5

• Added new default renderer for web: CanvasRenderer. This is a simple native Canvas renderer. This has been added as StageXLRenderer has performance issues with large scenes.
• Added demos for both StageXLRenderer and CanvasRenderer
• Demos moved over to use CanvasRenderer

0.4

• Added MajorityVote Rules
• Optimised BriansBrain processing
• Updated demos

0.3

• Added GameOfLifeSimple Rules. This simulation is a simpler version of GameOfLife, it only has binary states and implemented with minimal code
• Added BriansBrain Rules
• Updated demos

0.2

• Optimised cell processing, now only processes cells that neighbor active states
• Added tests (more to add)
• Improved StageXL bitmap colours crispness by adding frame margin

0.1

• Refactored so Rule's cell-states are now passed as generic types in to the Cell World for better analyzer & tooling support
• Added a CAGenerators for generating/seeding worlds
• Renderers are now further decoupled from the Simulation. They now just require an CellGrid containing states expressed in a palette.
• Added a very simple demo (simple_example.dart) to show minimum setup code
• CellWorld now stores full cell-states and Rules also deal with full cell-states which makes code more readable
• Fixed mathematical generators

0.0

• Initial version, includes basic implementation of GameOfLife with StageXLRenderer
• Hosted demos
