python - 简单游戏 list

Question

所以我再次尝试以正确的方式发布此内容，但我正在努力为类项目的一个非常简单的基于文本的游戏添加项目到库存中。输出应如下所示:

You are in (room)
Inventory: []
You see a (item)
What do you wish to do?

在我的游戏中，玩家将输入类似 get Sword 的命令。拿起一件物品。如果该项目不在房间内，则应输出 You cant get that item here .一旦玩家在房间里拿到物品，它应该被添加到物品栏中并从房间中移除，以便输入如下:

You are in (room)
Inventory: [Sword]
You dont see anything useful
What do you wish to do?

我在更新库存时遇到问题，然后物品不再在房间里。当我在房间里时，我试着去拿东西，上面写着 You cant get that item here即使物品在房间里。
以下是我的代码的简化版本，非常感谢任何帮助。

# A dictionary for the simplified text game that links a room to other rooms.
rooms = {
        'Entrance Hall': {'North': 'Great Hall', 'East': 'Gallery', 'West': 'Library', 'item': 'None'},
        'Library': {'East': 'Entrance Hall', 'item': 'Book'},
        'Gallery': {'West': 'Entrance Hall', 'item': 'Sword'}
    }

instructions = 'To move type: go North, go East, go West, go South' \
               'to get items type get Item, ex: get Sword\n '

directions = ['go North', 'go South', 'go East', 'go West']
pick_up_items = ['get Ale', 'get Book', 'get Armor', 'get Sword', 'Necromancer', 'get Knife', 'get Candle']

print(instructions)
current_room = 'Entrance Hall'
item_in_room = 'None'
inventory = []

while True:
    print('You are in the {}.'.format(current_room))
    print('Inventory:', inventory)
    if item_in_room == 'None':
        print("You don't see anything useful")
    else:
        print('You see a', item_in_room)

    # gets the users input
    command = input('\nWhat do you wish to do? ')  # this controls the movement
    if command in directions:
        command = command.split()[1]
        if command in rooms[current_room].keys():
            current_room = rooms[current_room][command]
            item_in_room = rooms[current_room]['item']
        else:
            # if the player inputs a bad movement
            print('You cant go that way!')
    # Checks to see if the player types a 'get' command and adds the item in the room to the players inventory.
    if command in pick_up_items:
        command = command.split()[1]
        if command in rooms[current_room].keys():
            inventory.append(current_room['item'])
        else:
            # if the player inputs a item not in the room
            print('You cant get that item here!')

就我所见，您对物品的检查是错误的。
您的商品在 rooms[current_room]['item']不是 rooms[current_room].keys()

if command == rooms[current_room]['item']:
    inventory.append(rooms[current_room]['item']) #another error i found out
    rooms[current_room]['item'] = 'None' #make sure that you check that command isn't None or it will be added as an Item
# other stuff

如果您打算在一个房间内放置多个物品，我建议您转换 item将所有字典键入一个列表，使检查更容易。另外， go item还将通过您的方向检查并引发错误。
