我一直在开发类似Zork的基于文本的冒险游戏，并将其作为个人项目来尝试“速成班”自学python。我是编码的新手，所以我对基础知识不太了解。
在游戏中，我可以成功导航到创建的地图，并可以自由添加新房间/物品。我目前正在努力使“广告资源”系统正常运行。
目前，我的Room类中有一个名为“ roominv”的字典，它用作每个特定房间的清单。在玩家类别中，我还有一个名为“ bag”的字典，可作为玩家清单使用。
目前，该游戏尚不完善，还没有完成，因此要捡起一件物品，您必须捡拾当前房间中的所有物品，但这并不是我遇到的麻烦。
玩家拿起房间中的物品后，我不知道如何清空roominv词典。现在，我可以将这些物品添加到播放器包中，但是它会创建一个副本而不将其从roominv中删除。
我尝试使用del，delattr和pop，但是我没有正确使用它们（这是我的假设），或者这不是正确的方法。我还尝试了.remove，我将其留在下面的代码中。它返回此错误消息
Traceback (most recent call last):
File "C:/Users/Daniel/Desktop/PythonPR/Flubbo'sLatestBuild.py", line 104, in <module>
player = Player("Jeff", 100, [], 'introd', command)
File "C:/Users/Daniel/Desktop/PythonPR/Flubbo'sLatestBuild.py", line 97, in __init__
addToInventory(self.room.roominv)
File "C:/Users/Daniel/Desktop/PythonPR/Flubbo'sLatestBuild.py", line 82, in addToInventory
Room.roominv.remove(item)
AttributeError: type object 'Room' has no attribute 'roominv'
这与使用del或delattr时出现的错误相同。
任何提示，建议或伪代码将不胜感激，如果我只是以完全错误的方式进行操作，请告诉我哈哈。
要开始游戏，您必须键入n，w，e或s 3次（错误），然后可以使用这些键四处走动或通过“取物”来拾取房间中的物品。

也可以随意批评我的代码！我正在尝试学习，有经验的人的任何建议/意见都很好。
最佳答案
虽然不是代码审查，但我还会添加一些指针来修复您的其他错误，但首先要解决的问题是：
Room.roominv.remove(item)
Room是一个类，而不是对象，因此您不能要求它的roominv相反，您将需要
self.room.roominv，但是由于.remove不是dict的成员而无法使用，我建议进行以下更改：您的
'Take Items'命令应为：elif command.split()[0] == 'Take':
for key in list(self.room.roominv.keys()):
if self.room.roominv[key].name == command.split()[1]:
addToInventory(key)
这将允许用户仅使用可用的特定项目，并允许用户指定他们要提取的项目。
然后，您的
addToInventory函数可以是：def addToInventory(self,key):
self.bag.append(self.room.roominv[key])
del self.room.roominv[key]
如果一个房间中有多个项目，这将仅删除给定的项目。
del关键字从字典中删除给定的键/项对。关于其他问题，您的错误在这里：
elif command == '':
print('You have to say what it is you want to do! Unfortunately due to a bug you must now restart the game. We are working on fixing this as soon as possible. Sorry!')
可以简单地通过更改
command来解决：elif command == '':
print('You have to say what it is you want to do!')
command = '#'
为了解决您需要多次输入指令的问题，建议您执行以下操作：
从代码顶部删除
command = input('>>> ')。将
command = input('>>> ')循环上方的while command != ""替换为command = ' '并更新您的
Player以不使用move（这意味着编辑__init__函数以及在代码底部player的player = Player("Jeff", 100, [], 'introd')初始创建）最后，挑剔，为什么不将
while循环放入函数中？所有这些导致：class Player:
def __init__(self, name, health, bag, room_name):
self.name = name
self.health = health
self.bag = bag
self.room = world[room_name]
def travel(self, direction):
if direction not in self.room.exits.keys():
print("You can't go that way!")
else:
new_room_name = self.room.exits[direction]
print("moving to", new_room_name)
self.room = world[new_room_name]
print(self.room.description)
print(self.room.actions)
def addToInventory(self, key):
self.bag.append(self.room.roominv[key])
del self.room.roominv[key]
def play(self):
command = " "
while command != "":
command = input('>>> ')
if command in {'n', 'e', 's', 'w', 'north', 'south', 'east', 'west', 'go north', 'go south', 'go east', 'go west'}:
self.travel(command)
elif command == 'look':
print(self.room.description)
print('Exits', self.room.exits.keys())
elif command == '':
print('You have to say what it is you want to do!')
command = '#'
elif command == 'search':
print(self.room.roominv)
elif command.split()[0] == 'Take':
itemTaken = False
for key in list(self.room.roominv.keys()):
if self.room.roominv[key].name == command.split()[1]:
self.addToInventory(key)
itemTaken = True
if not itemTaken:
print("I can't find that")
elif command == 'Inventory':
print(self.bag)
else:
print('Invalid command')
player = Player("Jeff", 100, [], 'introd')
player.play()
这些更改将导致需要进行其他一些更改，例如在查看库存时，打印出每个项目的
.name，而不是对象本身。完整的代码审查可能还会有更多更改，但是，您应该将代码发布到Code Review上，请注意，代码审查仅应用于完整的有效代码，因此请确保没有任何修改。在此发布游戏之前，请先打破游戏中的错误。
运行示例：
>>> n
moving to clearing
You are in a clearing surrounded by forest. Sunlight is streaming in, illuminating a bright white flower in the center of the clearing. To the South is the way you entered the forest. A well worn path goes to the East. In the distance a harp can be heard.
{'Go East', 'Take flower', 'Go south'}
>>> s
moving to introd
You are in a forest, you can hear wildlife all around you. There seems to be a clearing in the distance.
{'Search the ground', 'Go North'}
>>> n
