Question

我正在使用Ruby编写一个简单的基于文本的地下城游戏，但我遇到了麻烦。基本上，我有一个带锁门的房间。钥匙在另一个房间找到，我希望一旦找到钥匙就可以解锁门。

这是我到目前为止所得到的：

def chest_room
  puts "You are in a small, round room."
  puts "On the floor in front of you is a small wooden chest."
  puts "It does not appear to be locked."
  puts "What do you do?"
  chest_open = false

  while true
  prompt; next_move = gets.chomp
  if next_move == "open chest"
    chest_open = true
    puts "Inside the chest, you see a small, brass key."
    puts "What do you do?"
    prompt; next_move = gets.chomp
  elsif next_move == "take key" and chest_open
    key_present = true      
  puts "You take the key and slip it into a pocket."
    puts "What do you do?"
    prompt; next_move = gets.chomp
  elsif next_move == "go back"
    start()
  else puts "I don't understand you."
    puts "What do you do?"
    prompt; next_move = gets.chomp
    end
  end
end  

def start
  puts "You find yourself in a dank room lit by torches."
  puts "There are three doors leading out of here."
puts "What do you do?"
door_open = false
key_present = false
while true
  prompt; next_move = gets.chomp
  if next_move == "door 1"
    chest_room()
  elsif next_move == "door 2"
    dais()
  elsif next_move == "door 3" and not door_open
    puts "This door is securely locked."
    puts "You'll need to find some way of opening it before you can enter."
    puts "What do you do?"
    prompt; next_move = gets.chomp
  elsif next_move == "door 3" and key_present
    door_open = true
    puts "The key you found fits easily into the lock."
    puts "With a click, you unlock the door!"
    orb_room()
  else 
    puts "I don't understand you."
    puts "What do you do?"
    prompt; next_move = gets.chomp
    end
  end
end

任何意见或建议？基本上，我想在找到密钥后结束door_open = false循环，但我无法弄清楚如何在chest_room方法中设置door_open = true然后从start方法调用它。谢谢！

Answer 1

你真正需要的是备份并再次思考设计。您有一个房间，它有一个“开放”或“关闭”的属性。你有一把钥匙，你需要钥匙来改变那个开/关房产的状态。

写出你想做的事情，并考虑如何将它建模为房间和钥匙，你将会走得更好。

（不，我不想给你答案。弄清楚它更重要。）

你有范围问题。通过在它们前面加上@来制作door_open或key_present实例变量。然后任何方法都可以访问它们。案例/何时比elsif更清洁

while !@key_present # @key_present can be modified in another method
  prompt; next_move = gets.chomp
  case
    when "door 1" == next_move then chest_room() # put constants first when comparing ==
    when "door 2" == next_move then dais()
    # more conditions
  end
end

从Ruby中的另一个方法结束一个方法中的循环？
