Question

我的RNG猜谜游戏似乎不断产生一个新号码，而不是保存游戏当前会话的数量供玩家猜测。

def initialize
  @@answer = rand(1..100).to_s
end

def answer
  @@answer
end


def guessing
  puts "What's your guess?"
  @@guess = gets.chomp.downcase
  while @@guess != answer
    wrong_answer
  end
  right_answer
end

Answer 1

我没有看到您的代码有任何问题，但它可能是初始化类的方式（如果您在每次想要猜测时都明确地调用猜测）。

您需要将初始化的类存储在变量中：

guess = Guess.new
guess.guessing
guess.guessing

除非必要，否则您不想使用类实例变量，例如，使用@guess，@answer代替@@guess和@@answer。

另一种方式

  def guessing
    puts "What's your guess?"
    @guess = gets.chomp.downcase
    while @guess != answer
      puts "wrong_answer"
      @guess = gets.chomp.downcase
    end
    puts "right_answer"
  end

Answer 2

我认为如果将随机数存储在attr_reader中，则可以引用它并将其与猜测进行比较。如果您将猜测存储在attr_accessor中，您可以将猜测与存储的随机数进行比较，并让用户通过更新猜测继续游戏，直到它与随机数匹配。我可以包含一个示例，您可以将其复制并粘贴到IRB中。要开始游戏，只需致电PlayGame.new，即可开始运行。输入cheat作为随机数，输入hint作为提示。

class RandomNumber
  attr_reader :number

  def initialize
    @number = rand(1..100).to_s
  end

  def hint
    random_number = number.to_i

    puts case
    when random_number >= 75
      "Your number is in the range of 75 to 100"
    when random_number >= 50
      "Your number is in the range of 50 to 74."
    when random_number >= 25
      "Your number is in the range of 25 to 49"
    else random_number > 0
      "Your number is 24 or less."
    end
  end
end

class PlayGame
  attr_accessor :input
  attr_reader :number

  def initialize
    @generate_number = RandomNumber.new
    @number = @generate_number.number
    puts "What's your guess?"
    @input  = gets.chomp.downcase
    validate
  end

  def validate
    case
    when input == number
      puts "You win!"
    when input == "cheat"
      puts "The number is #{number}"
      get_guess
    when input == "hint"
      @generate_number.hint
      get_guess
    else
     get_guess
    end
  end

 def get_guess
   puts "Try again, what's your guess?"
   @input = gets.chomp.downcase
   validate
 end
end

随机数生成器似乎没有保存数字
