##Chess Game on Rails

This repo contains the skeleton backend logic in order to produce an online chess application. The aim is to turn this logic into a Rails Api and build a javascript application to work in tandem with the API.

The application was built using ruby 2.2.2.

####How to Run the Application

Once the Repo has been cloned, the relevant gems need to downloaded. If you have Bundler installed, you can do this by using the bundler command in terminal:

$ bundle

The database then needs to created, migrated and seeded. To do this use the following commands in terminal:

$ rake db:create
$ rake db:migrate
$ rake db:seed

The database should now be setup and ready for use.

Firstly a player should be created:

$ player1=Player.create(name:'name',colour:'white',status:'playing')

Always create a player with the status 'playing' and with an associated colour. To move a piece you first have to find the piece in the database. For example if you wanted to move the pawn at A2 to A3, you should first querie the database to look for a pawn at A2.

$ pawn = Pawn.find_by(position:'A2')

To move, simply instruct the player to move the piece and where to.

$ player.move pawn, 'A3'

#####Check and Check Mate

Piece's will be taken off the board when another piece occupies the cell they are in. To check to see if a player is in check or check mate, the board has to be queried first.

$ board = Board.first
$ board.in_check? 'white' # to check if white is in check, 'black' can also be entered as an argument.
$ board.check_mate? 'black' # to check if black is in check mate.

Tests were written in the Rspec testing suite. To run all tests use the rspec command to run the whole suite, or follow rspec with a file path to run tests in isolation.

$ rpec
$ rspec <-file_path->
