As part of the odin project I've written this bit of code that allows two users to play a game of Tic Tac Toe. I'm still a relative newbie to Ruby and to coding and am guessing that there are much better ways to do what I've done here. I'd love to get input, suggestions and recommendations.
The full code is below but can also be found here.
class TicTacToe
def initialize
@game = Game.new("Chris", "Lisa")
end
class Game
attr_accessor :player1, :player2
def initialize (player1, player2)
@player1 = Player.new(player1)
@player2 = Player.new(player2)
@winning = [[1,2,3], [4,5,6], [7,8,9], [1,4,7], [2,5,8], [3,6,9], [1,5,9], [3,5,7]]
@symbol1 = "X"
@symbol2 = "O"
self.start
end
def start
introduction
player_names
player_assignment
display_board(@winning)
play_game
end
def introduction
puts "Welcome to TicTacToe. We will now randomly choose who goes first. Press any key to begin."
puts ""
@@input = gets.chomp
end
def player_names
puts "Please enter the name of a player."
name1 = gets.chomp
puts ""
puts "Please enter the name of another player."
name2 = gets.chomp
@player1.name = name1
@player2.name = name2
end
def player_assignment
@x = rand(10)
if @x <= 5
@player1.symbol = @symbol1
@player2.symbol = @symbol2
puts ""
puts "#{player1.name} is assigned #{@symbol1} and #{player2.name} is assigned #{@symbol2}"
puts ""
else
@player1.symbol = @symbol2
@player2.symbol = @symbol1
puts ""
puts "#{player1.name} is assigned #{@symbol2} and #{player2.name} is assigned #{@symbol1}"

end
