Question

我正在使用方法构建命令行ruby二十一点游戏。我已经达到了玩家可以击中或坚持的程度（在获得2张牌之后）。现在我似乎无法在逻辑上思考如何将我的玩家限制在四次点击。制作

这告诉我，我的问题是循环 - 也就是说我正在以错误的方式接近程序的循环部分。

到目前为止，这是我的代码：

def blackjack
  promt
end

def promt
  puts "Welcome! Would you like to play a game of blackjack? Enter Yes or No"
  play = gets.chomp.downcase
  if play == "yes"
    game_plan
  elsif play =="no"
    puts "That's too bad. Come back when you feel like playing"
  else
    puts "Sorry but I don't understand your respones. Please type and enter yes to play Or no to to quit"
    blackjack
  end
end

def game_plan
  wants_to_play = true
  hand = []
  total = first_move(hand)
  wants_to_play = hit_me(hand)
  if wants_to_play == true
    hit_me(hand)
  end
end

def first_move(hand)
  deal(hand)
  deal(hand)
  total(hand) 
end

def deal(hand)
  card = rand(12)
  puts "You have been dealt a card with a value of #{card}"
  hand << card
end

def total(hand)
  total = 0
  hand.each do |count|
    total += count
  end
  puts "The sum of the cards you have been dealt is #{total}"
  total
end

def hit_me(hand)
  puts "Would you like to hit or stick?"
  yay_or_nah = gets.chomp.downcase
  if yay_or_nah == "stick" && total(hand) < 21
    puts "Sorry! The sum of the cards you have been dealt is less than 21. You lost this round!"
  else
    deal(hand)
    total(hand)
    playing = true
  end  
end

我想要做的是将我的玩家限制为2次点击（在最初的第一次击中之后，它会产生2张牌）。我知道这是一个非常烦人的新手问题，但我真的很感激任何能够帮助我以正确的方式思考解决方案的反馈。

PS：虽然我理解循环是如何工作的但我知道如何以及何时实施它们正在进行争论......所以任何反馈都会非常感激。谢谢！

你在寻找类似的东西吗？

MAX_HITS = 2
hits = 0
loop do
  break if hits > MAX_HITS
  puts "Would you like to hit or stick?"
  …
  else
    hits += 1
    …
  end
end
