Ruby 我不知道为什么这个石头、布、剪刀的游戏不起作用

我不知道这个游戏有什么问题：

print "Welcome to Rock, Paper, Scissors!"
print "
All outcomes are randomly generated and independent from your answer."
puts "

Rock, paper, scissors:"
answer = gets.chomp!
answer.capitalize!

cpu = 3

if cpu == 1
  cpu = "Rock"
end

if cpu == 2
  cpu = "Paper"
end

if cpu == 3
  cpu = "Scissors"
end

print "
Your answer: #{answer}
CPU answer: #{cpu}"

if cpu == answer
  print "
  Winner: It's a tie"
end

if answer = "Rock" && cpu = "Paper"
  print  "
  Winner: CPU"
end

if answer = "Rock" && cpu = "Scissors"
  print "
  Winner: Human"
end

它在最后输出所有可能的答案，例如：

Your answer: Rock
CPU answer: Scissors
  Winner: CPU
  Winner: Human

在代码末尾，有几个地方您意外地使用了赋值运算符=，而不是等式检查运算符=。

Alexander

代码末尾有两个错误

在if条件中，replace=to==

if answer == "Rock" && cpu = "Paper"
  print  "
  Winner: CPU"
end

if answer == "Rock" && cpu = "Scissors"
  print "
  Winner: Human"
end

这里有一个更像Ruby的方法来解决您的问题

WINS = { "rock"=>"scissors", "paper"=>"rock", "scissors"=>"paper" }

def outcome(first, second)
  return :WIN  if WINS[first]  == second
  return :LOSE if WINS[second] == first
  :TIE
end

outcome("rock", "scissors") #=> :WIN
outcome("rock", "paper")    #=> :LOSE
outcome("rock", "rock")     #=> :TIE

在最后两个if中，您使用=，而不是将它们与==进行比较。我发现很难识别这些多行print和put语句。我对Ruby相当陌生，我不知道这个游戏有什么问题-现在是学习一些调试技巧的最佳时机。会让你更加自主，而不是像鱼一样离开水。我用了很多技巧。谢谢大家的帮助。看起来很好用
