## About the code
#### Used technologies
* [AndroidAnnotations](https://github.com/excilys/androidannotations) 
* [Otto](square.github.io/otto/) 
* [Hugo](https://github.com/JakeWharton/hugo)

#### Running tests
Type ```./gradlew app:test```.

Results can be checked in the generated HTML under ```app/build/reports/tests/debug/index.html```

#### Tampering around
The code is intentionally implemented in a way to make it easy to create other types of cellular automata. Feel free to fork it and play around. For a starter:

1. Add your own implementation for Rule and CellularAutomata, and for CellColors if your automaton needs more than a basic dead / alive coloring:
   * [Rule](https://github.com/zsoltk/GameOfLife/tree/master/app/src/main/java/hu/supercluster/gameoflife/game/rule)
   * [CellullarAutomaton](https://github.com/zsoltk/GameOfLife/tree/master/app/src/main/java/hu/supercluster/gameoflife/game/cellularautomaton)
   * [CellColors](https://github.com/zsoltk/GameOfLife/tree/master/app/src/main/java/hu/supercluster/gameoflife/game/visualization/cell)

2. Use them in:
   * [MainPresenter](https://github.com/zsoltk/GameOfLife/blob/master/app/src/main/java/hu/supercluster/gameoflife/app/activity/main/MainPresenter.java)

3. If you're interested how the transformation is done, check:
   * [Transformer](https://github.com/zsoltk/GameOfLife/tree/master/app/src/main/java/hu/supercluster/gameoflife/game/transformer)

4. Have fun and message me if you create something cool!

#### Known limitations
The approach used in the transformation logic is that only cell state changes are observed, and a counter of dead / alive neighbors is updated in every surrounding cell. By using the [ThreadedGridTransformer](https://github.com/zsoltk/GameOfLife/blob/master/app/src/main/java/hu/supercluster/gameoflife/game/transformer/ThreadedGridTransformer.java) it's fast enough to be smooth for Game of Life and most other rules. However, rules resulting in lots of changes around the screen might slow the game down.
