使用ruby def比较的石头剪刀纸牌游戏不起作用

我试着创造这个游戏。这是我的密码：

puts "Welcome to our Rock, Paper, Scissors Game"

puts "Do you want to play? (yes/no)"
answer = gets.chomp.downcase
while answer == "yes" do

options = ["rock", "paper", "scissors"]
computer_choice = options[rand(options.length)]

puts "Please choose Rock, Paper or Scissors!"
player_choice = gets.chomp.downcase

def compare
  if (player_choice == "rock" && computer_choice == "scissors")
    puts "computer choice is: " + computer_choice + " , you win! :)"
  elsif (player_choice == "rock" && computer_choice == "paper")
    puts "computer choice is: " + computer_choice + " ,computer wins :("
  elsif (player_choice == "paper" && computer_choice == "scissors")
    puts "computer choice is: " + computer_choice + " ,computer wins :("
  elsif (player_choice == "paper" && computer_choice == "rock")
    puts "computer choice is: " + computer_choice + " , you win! :)"
  elsif (player_choice == "scissors" && computer_choice == "rock")
    puts "computer choice is: " + computer_choice + " ,computer wins :("
  elsif (player_choice == "scissors" && computer_choice == "paper")
    puts "computer choice is: " + computer_choice + " , you win! :)"
  elsif (player_choice === computer_choice)
    puts "It's a tie!"
  else
    puts "Error"
  end
end
end

它重复询问我的选择，而不进行def比较。我遗漏了什么？

让我们把它分成三部分。首先，让我们编写游戏的主循环：

puts "Welcome to our Rock, Paper, Scissors Game"

loop do
  puts "Do you want to play? (yes/no)"
  answer = gets.chomp.downcase
  if answer == "yes"
    play_game
  elsif answer == "no"
    puts "Bye!"
    break
  elsif
    puts "Invalid answer (must be 'yes' or 'no')"
  end
end

def play_game 
  options = ["rock", "paper", "scissors"] 
  computer_choice = options.sample 

  loop do 
    puts "Please choose Rock, Paper or Scissors!" 
    player_choice = gets.chomp.downcase 
    if options.include?(player_choice) 
      compare(player_choice, computer_choice) 
      break 
    else 
      puts "Invalid answer (must be 'rock', 'paper' or 'scissors')" 
    end 
  end 
end 

def compare(player_choice, computer_choice) 
  puts "Computer choice is: " + computer_choice + ". " 

  if(player_choice == "rock" && computer_choice == "scissors") 
    puts "You win! :)" 
  elsif(player_choice == "rock" && computer_choice == "paper") 
    puts "Computer wins :(" 
  elsif(player_choice == "paper" && computer_choice == "scissors") 
    puts "Computer wins :(" 
  elsif(player_choice == "paper" && computer_choice == "rock") 
    puts "You win! :)" 
  elsif(player_choice == "scissors" && computer_choice == "rock") 
    puts "Computer wins :(" 
  elsif(player_choice == "scissors" && computer_choice == "paper") 
    puts "You win! :)" 
  else 
    puts "It's a tie!" 
  end 
end 


puts "Welcome to our Rock, Paper, Scissors Game" 

loop do 
  puts "Do you want to play? (yes/no)" 
  answer = gets.chomp.downcase 
  if answer == "yes" 
    play_game 
  elsif answer == "no" 
    puts "Bye!" 
    break 
  elsif 
    puts "Invalid answer (must be 'yes' or 'no')" 
  end 
end

这修复了您的第一个问题，即“您想玩吗”实际上没有被循环

现在，让我们定义

play_game

方法：

def play_game
  options = ["rock", "paper", "scissors"]
  computer_choice = options.sample

  loop do
    puts "Please choose Rock, Paper or Scissors!"
    player_choice = gets.chomp.downcase
    if options.include?(player_choice)
      compare(player_choice, computer_choice)
      break
    else
      puts "Invalid answer (must be 'rock', 'paper' or 'scissors')"
    end
  end
end

def compare(player_choice, computer_choice)
  puts "Computer choice is: " + computer_choice + ". "

  if(player_choice == "rock" && computer_choice == "scissors")
    puts "You win! :)"
  elsif(player_choice == "rock" && computer_choice == "paper")
    puts "Computer wins :("
  elsif(player_choice == "paper" && computer_choice == "scissors")
    puts "Computer wins :("
  elsif(player_choice == "paper" && computer_choice == "rock")
    puts "You win! :)"
  elsif(player_choice == "scissors" && computer_choice == "rock")
    puts "Computer wins :("
  elsif(player_choice == "scissors" && computer_choice == "paper")
    puts "You win! :)"
  else
    puts "It's a tie!"
  end
end

这修复了你的第二个问题，玩家在每个游戏中都陷入了无限循环

最后，让我们定义

compare

方法：

def play_game
  options = ["rock", "paper", "scissors"]
  computer_choice = options.sample

  loop do
    puts "Please choose Rock, Paper or Scissors!"
    player_choice = gets.chomp.downcase
    if options.include?(player_choice)
      compare(player_choice, computer_choice)
      break
    else
      puts "Invalid answer (must be 'rock', 'paper' or 'scissors')"
    end
  end
end

def compare(player_choice, computer_choice)
  puts "Computer choice is: " + computer_choice + ". "

  if(player_choice == "rock" && computer_choice == "scissors")
    puts "You win! :)"
  elsif(player_choice == "rock" && computer_choice == "paper")
    puts "Computer wins :("
  elsif(player_choice == "paper" && computer_choice == "scissors")
    puts "Computer wins :("
  elsif(player_choice == "paper" && computer_choice == "rock")
    puts "You win! :)"
  elsif(player_choice == "scissors" && computer_choice == "rock")
    puts "Computer wins :("
  elsif(player_choice == "scissors" && computer_choice == "paper")
    puts "You win! :)"
  else
    puts "It's a tie!"
  end
end

您可能可以进一步改进该方法，但我至少删除了

put

语句之间最大的重复

综上所述，这是一个完整的游戏版本：

puts "Welcome to our Rock, Paper, Scissors Game"

loop do
  puts "Do you want to play? (yes/no)"

  if answer == "yes"
    play_game
  elsif answer == "no"

有很多方法可以进一步改进，但我将留给您。

考虑使用散列：

h={“rock”=>“剪刀”，“paper”=>“rock”，“剪刀”=>“paper”}

。然后玩家赢如果

h[player\u choice]==computer\u choice

，计算机赢如果

h[computer\u choice]==player\u choice

，否则是平局。试试这样的结构。

loop do；puts“keep playin”；“break if”get.chomp.downcase==“n”；loop do；puts“what's your choice？”；player\u choice=get.chomp；if h.有钥匙？（player\u choice）谢谢，你的想法教了我很多。谢谢，你的想法教了我很多。考虑使用哈希：<代码> H= {岩石〉=“剪刀”，“纸”=“摇滚”，“剪刀”=“纸”} /代码>。然后玩家获胜，如果<代码> h [ PalryOrthOrth] =计算机选择> <代码>，计算机获胜如果<代码> h [计算机选择]==player\u choice

，否则是平局。尝试这样的结构。

循环do；放置“继续播放”？“如果”get.chomp.downcase==n；循环do；放置“你的选择是什么？”；player\u choice=get.chomp；如果h.有_键？（player\u choice）；；中断；否则；放置“{player\u choice}”无效，请重试”；end；end

。谢谢，你的想法教会了我很多！非常感谢你的建议！我尝试了你的几个想法，学到了很多，谢谢！非常感谢你的建议！我尝试了你的几个想法，学到了很多，谢谢！
