红宝石二十一点和循环

Question

我正在建造一个命令行红宝石二十一点游戏使用的方法。我已经到了玩家可以击中或坚持的地步（在被交易2张牌之后）。现在我似乎无法跳出逻辑思考如何限制我的球员只有四个命中。 make

这告诉我，我的问题在循环 - 那就是我正以错误的方式接近程序的循环部分。

这是到目前为止我的代码：

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 

blackjack 

我想要做的是限制我的球员命中2（初始先打，其中涉及2张卡后）。我知道这是一个令人讨厌的新手问题，但我真的很感谢任何能够帮助我以正确的方式来思考解决方案的反馈。

PS：虽然我理解循环的工作方式，但我知道如何以及何时实施它们......所以任何反馈都将非常感激。谢谢！

你在找那种东西吗？

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
