mspwong / checkers Goto Github PK

This application validates a proposed move during a checker game.  It handles only regular moves with the caveat that a piece may not moved into a square that is occupied by another piece of either color.

The position of all pieces at any given time is persisted in the database.  No performance tuning such as caching is attempted in this solution.

The x and y coordinates are taken from the checkers board images shown here:  http://www.jimloy.com/checkers/rules2.htm
[1,1] denotes the bottom left square
[8,1] denotes the bottom right square
[8,1] denotes the top left square
[8,8] denotes the top right square

The starting board has following fixtures in the following positions:
pieces(:white_1) in [1,1]
pieces(:white_4) in [7,1]
pieces(:white_12) in [7,3]
pieces(:red_1) in [2,6]
pieces(:red_4) in [8,6]
pieces(:red_12) in [8,8]
