Question

我对编程很新，我正在尝试创建一个非常简单的地下城游戏。我有大部分工作，但我有一个小问题。这是我的代码：

print("Welcome to Matt's Dungeon!")

user = ""
stop = "q"

while user != "q":
first = input("You are in the kitchen. There are doors to the south (s) and east (e). ")
if first == "s":
    print("You entered the furnace and fry yourself to death!")
    break
elif first == "q":
    break
elif first == "e":
    second = input("You are in the hallway. There are doors to the west (w), south (s), and east (e). ")
    if second == "w":
        first == "s"
    elif second == "q":
        break
    elif second == "e":
        print("You are in the library. You found the princess! You are a hero!")
        break
    elif second == "s":
        third = input("You are in the living room. There are doors to the west (w) and north (n). ")
        if third == "w":
            print("You entered the furnace and fry yourself to death!")
            break
        elif third == "n":
            first == "e"
        elif third == "q":
            break


print("Goodbye!")

我遇到的问题是，如果用户在客厅输入“n”，我希望它回到走廊，但程序总是把它送回原来的厨房。但是，如果用户在走廊中输入“w”，则工作正常并将其返回到前一个房间，即厨房。关于我如何解决这个问题的任何想法？提前感谢您的帮助！

Answer 1

您可以使用由代表房间的钥匙和您可以去的地方列表的值组成的dictionary。

例如：

# these match up to indexes for the list in the dict directions
NORTH = 0
EAST = 1
WEST = 2
SOUTH = 3

directions = {
    "living room": ["dining room", None, None, "bedroom"]
}

# the current room, represented by the keys you create
current_room = "living room"
# an example imput
direction = "n"

if direction == "n":
    possible_room = directions[current_room][NORTH]
    if possible_room:
        current_room = possible_room

一些非常草率的示例代码，但它得到了我的观点。提出一个程序的一般想法是研究如何存储数据，例如在Python中使用字典。

Python有很多值得研究的数据类型。

我会让你现在修复代码，因为你已经获得了解决问题的新视角。

Answer 2

你的缩进搞砸了。

将first = input("You are in the kitchen. There are doors to the south (s) and east (e). ")放在while循环之前。

Answer 3

让我们忽略你可能错误复制的缩进问题。

你的控制流程非常混乱。基本上让我们来看看你的基本结构：

while True:
  first = input("You are in kitchen")     
  # additional program logic

你能明白为什么，无论你在这里做的其余逻辑是怎么回事，你都会在continue之后回到厨房吗？

获得实际需要的结构的一个选择是按顺序编程。这是一个设计游戏的可能方式的伪代码示例，其中一些设计部分是故意未指定的。我提供这个可以让你思考如何以一种有意义的方式设计游戏。

class Room():
  def __init__(self,north,south,east,west):
    self.north=north
    self.south=south
    self.east=east
    self.west=west

kitchen = Rooms(None, 'hallway', 'library', None)
#initialization of other rooms are left as excercise to the reader

current_room = kitchen

while True:
  print "You are in the %s" % current_room
  move=raw_input("Where do you want to go")
  if move=='q':
    print "bye"
  if move=='e':
    current_room = current_room.east

  #much logic is left as an exercise to the reader

我如何返回更高的上行并让它在Python中执行？
