Minesweeper is written in Ruby. It can be run in the terminal with "ruby game.rb"
Enter a move as three space separated arguments - row, column, and c for click or f for flag. To save or load a game, type save or load at any time with an optional -f filename.
Minesweeper uses a recursive function to clear tiles on click. Upon click, it will check if neighboring tiles have already been revealed, and if not, it will reveal them and call click on each, unless the tile has been flagged or has a neighboring bomb.
The save system uses Ruby's file I/O to write the current state of the game to a YAML file. On load, it will recreate the saved game state using YAML::load.
def save(input)
if input.include?('-f')
filename = input[-1]
else
filename = 'saved_game.txt'
end
File.open(filename, 'w') { |file| file.write(self.to_yaml)}
puts 'Game saved'
end
def load(input)
if input.include?('-f')
filename = input[-1]
else
filename = 'saved_game.txt'
end
game_file = File.open(filename, 'r') { |file| file.read}
game = YAML::load(game_file)
puts 'Game loaded'
game.play
endThe colorize gem is used while iterating through tiles to create a pleasing and easy to read output.
