ブラックジャックのシミュレーションを作成しようとしています。以下はコードです...
one_suit = [2,3,4,5,6,7,8,9,10,10,10,10,11]; #the value of the cards for blackjack
full_deck = one_suit*4; #clubs, diamonds, hearts and spades
$deck = full_deck; #start off the game with a full deck
class Player
attr_accessor :ace_count
attr_accessor :hand_value
def initialize(ace_count,hand_value)
@ace_count = ace_count;
@hand_value = hand_value;
end
def self.hit
choice_of_card = rand($deck.length); #choose a random card out of the deck
drawn_card = $deck[choice_of_card]; #draw that random card from the deck
if drawn_card != 0 #if there is a card there
$deck[choice_of_card] = 0; #remove that card from the deck by making the space blank
if drawn_card == 11 #if you draw an ace
self.ace_count += 1;
end
self.hand_value += drawn_card ;
else hit; #if there is no card at that space then redraw (recursion)
end
end
end
player1 = Player.new(0,0);
player1.hit;
ただし、実行すると、次の出力が得られます。
NoMethodError: C:\Users\Ernst\Documents\JRuby\blackjack.rb:30 の # (ルート) に対する未定義のメソッド「hit」
私は何を間違っていますか?メソッドはクラス内で定義されます。
