A very crude Blackjack.

Mackie · **Posted:** Sun Apr 06, 2008 9:49 pm

Here is a very crude blackjack, I'm just trying to learn ruby, so I thought it would be a fun project to try out. It's pretty crude, I'm actually making a really cool deck class for super-accurate shuffling, and probability.

I'd love feed back/things I did wrong. Trying to get out of the Turing mindset proves difficult.

Ruby:

# Mackie Drew
# Black Jack
# April 6th, 2008

# Set defaults
dealerCards = [rand(10),rand(10)]
playerCards = [rand(10),rand(10)]
playAgain = "1"

# Pushes Screen Down
def cls
puts "\n" * 22
end

def total(hand)
total = 0
0.upto(hand.size){|i| total += hand[i].to_i}
total.to_i
end

def end_of_round(playerHand, dealerHand)
puts "Dealer's Total: #{total(dealerHand)}"
puts "Your Total: #{total(playerHand)}\n\n"

if total(playerHand) > 21 :
puts "Bust!\nYou Lose. :("
playAgain = "2"
elsif total(dealerHand) > 21 :
puts "Dealer Bust!\nYou Win!"
playAgain = "2"
else
if total(playerHand) > total(dealerHand) :
puts "You Win!"
else
puts "Dealer Wins. :("
end
end
end

#Title Menu
cls
puts "-----Mackie's Black Jack-----"
puts "1: New Game"
puts "2: Exit"

menuChoice = gets

while menuChoice.include?("1") :

while total(dealerCards) < 16 :
dealerCards += [rand(10)]
end

while playAgain.include?("1") :

cls
puts "Dealers Hand: #{dealerCards[0]}, #{dealerCards.collect{|x| if x > 3 : "??, " end}}\n"
puts "Your Hand: #{playerCards.collect{|x| x.to_s + ", "}}"
puts "Your Total: #{total(playerCards)} \n\n\n\n\n\n\n"

puts "1: Hit"
puts "2: Stay"

turnChoice = gets

if turnChoice.include?("1") :
playerCards += [rand(10)]
if total(playerCards) > 21 :
playAgain = "2"
end
elsif turnChoice.include?("2") :
playAgain = "2"
end
end

cls

end_of_round(playerCards, dealerCards)

puts "\n1: Play Again"
puts "2: Exit"
playAgain = gets
if playAgain == "2\n" :
menuChoice = "2"
playAgain = "2"
else
dealerCards = [rand(10),rand(10)]
playerCards = [rand(10),rand(10)]
playAgain = "1"
end

end

code:

def cls
puts "\n" * 22
end

code:

def clear_screen
22.times { puts }
end

code:

if turnChoice.include?("1") :
playerCards += [rand(10)]
if total(playerCards) > 21 :
playAgain = "2"
end
elsif turnChoice.include?("2") :
playAgain = "2"
end

Try making use of regular expressions instead of include? Smile

Thanks wtd, I changed it, I just don't know if there is any advantage to the change. Is it just common practice to do it your way?

I had a feeling someone was going to mention that. Razz

I wasn't sure why regular expressions weren't working until later on, when i realized it added the eol character.

Which is more self-documenting?
