Question

请原谅我的全局变量，这是我正在研究的一个Hangman项目。除了这个方法的一部分外，一切都正常。

def choice(n)
  $random_word2.each_with_index do |i,index|
    if i == n
      $cipher[index] = i 
    end 
  end 
    if n == $random_word
      puts "You win"
    end
    if $random_word2.include?(n) == false
      $counter -= 1
      display
      puts "incorrect guess"
    end
  puts $cipher.join 
end

特别是这些行。因为它是打印$ random_word所以你会知道它是什么，因为它是随机的。如果你输入整个单词，它应该打印“你赢了！”但它跳过最后一个“如果”并接受它作为一个不正确的猜测。我尝试了不同的变量并且它有效，所以这让我相信$ random_word变量在某个时候变成了一个不同的随机单词？我输了，它打印出来的字，我输入完全相同的东西，不知怎的，它不是==。

if n == $random_word
  puts "You win"

这是整个计划。

 load 'display.rb'

class Hangman
  attr_accessor :name
  @name = name

  def initialize
    puts "What is your name?"
    @name = gets.chomp
    puts "

Welcome #{@name} to Hangman. The computer will generate
a 5-12 letter random word. You will try to guess
that word one letter at a time. Try to solve the
puzzle before time runs out!

$counter = 5
while $counter > 0
choice(gets.chomp)
    end

Answer 1

更改为

File.foreach('5text.txt') do |x|
  chomped = x.chomp
  $array << chomped if (chomped.length >= 5 and chomped.length <= 12)
end

因为您的原始程序中的单词\n没有被限制。
