Game of Life (Rails Project)

My implementation of John Conway's Game of Life.

This project was made with Ruby v3.0.2 and Rails v7.0.4.2.

Database is PostgreSQL and caching is handled with Redis.

Game Instructions

This game follows the original rules but also adds a "Pac-Man Effect" on every border.

After signing up or logging in, you will be redirected to the main page where you will be prompted to either generate a new board by selecting a size from 10 to 40 or to import a JSON file to restore the state of a board.

If you're unhappy with the generated board, you may click on RANDOM to generate a new random board.

You can also toggle the alive/dead state of any cell while the game is not running.

Select your desired game SPEED by choosing from three different options:

• SLOW -> 2000ms
• NORMAL -> 1000ms (this is default)
• FAST -> 500ms

Press START to start the game and watch as life evolves and the GEN count increases.

Press STOP to pause the game.

Press NEXT to load the next generation only.

You can also CLEAR the board and draw your own.

Finally, you can EXPORT the current board to a JSON file.

If the game reaches a standstill, it will stop and recommend that you generate a new board or make some custom changes.

Development Setup

Make sure to have Ruby v3.0.2, Rails, PostgreSQL and Redis installed on your machine.

Make sure to have both PostgreSQL and Redis services up and running.

You may need to change the REDIS_URL environment variable in config/environments/development.rb.

Change development variables in config/database.yml according to your PostgreSQL setup.

Open a shell at the root of this project and run:

$ bundle install
$ ruby bin/rails db:prepare
$ ruby bin/rails server

Navigate to http://localhost:3000.
