Overview

An object oriented take on the minesweeper game that’s done in 131. Since it is un-Rubylike to use 2d arrays, I’m going to try and make the game using a more object oriented approach.

Instance Method Details

#find_adjacent_bombs ⇒ Object

Method will iterate through the surrounding GameTiles to check how many bombs there are. The method returns the number of bombs that are adjacent to itself.

def find_adjacent_bombs
  @adjacent.each do |key, value|
    begin
      if value.is_bomb?
        @adjacent_bombs += 1
      end
    rescue
      # This rescue catches the NoMethodError that arises when trying to call the find_adjacent_bombs 
      # method on an edge cell. The error arises when trying to access the is_bomb attribute of a 
      # nil class. Hence, the NoMethodError.
    end
  end
end

#find_adjacent_zeroes ⇒ Object

This method will “play” all of the adjacent cells that have zero mines surrounding them. The minesweeper game that comes standard with most computers has this behavior.
