I am creating a text based adventure game for a class and having trouble getting my inventory system to work

问题

以下是您要翻译的内容：

"对于上一周在我的课堂上的作业，我们必须创建一个简单的工作游戏，允许移动房间。我已经将该代码调整到我的游戏代码中，似乎可以正常工作，甚至将'Item'添加到我的字典中也没有问题。但是，一旦我尝试将物品添加到库存并引用库存列表到字典键，就会出现'不可散列'错误。我查了一下，但唯一清除错误的方法是使用元组，但元组是不可变的，所以我无法像我理解的那样将物品添加到库存。任何指导或建议都将不胜感激！

这是迄今为止的整个代码，一切都正常工作，直到我尝试添加一个单独的玩家库存。我还没有添加游戏结束代码，所以我意识到我有一个无限循环，但我想在添加结束之前使库存工作，因为库存必须包括所有物品才能获胜。"

英文:

For the previous week's assignment in my class we had to create a simple, working game that allowed moving rooms. I have adjusted that code into my game code and it seems to work fine, even with the addition of 'Item' into my dictionary. Once I try to add to the inventory and reference the inventory list to the dictionary keys I get an 'unhashable' error. I looked this up but the only way to clear the error is to use a tuple, but a tuple is immutable so I wouldn't be able to add to the inventory, at least as I understand it. Any guidance or suggestions is much appreciated!

    # main menu and game commands
    print(&#39;Move Commands: go North, go South, go West, go East&#39;)
    print(&quot;Add to inventory: get &#39;item name&#39;.&quot;)

                &#39;Garderobe&#39;: {&#39;South&#39;: &#39;Cabinet&#39;, &#39;Item&#39;: &#39;Torch&#39;}
                }

current_room = &#39;Entry Hall&#39;  # define starting room
inventory = []  # define string for inventory


def player_commands(command, direction):  # function for moving rooms
    global current_room  # declare current room as global
    global inventory  # declare inventory as global
    if command == &#39;go&#39;:
        if direction in castle_rooms[current_room]:  # establishing valid direction
            current_room = castle_rooms[current_room][direction]
        elif direction not in castle_rooms[current_room]:  # error message for invalid direction
            print(&quot;You can&#39;t go that way&quot;)
            current_room = current_room

    elif command == &#39;get&#39;:
        if direction in current_room:
            inventory.append(direction)
        current_room = current_room
    else:
        print(&#39;Invalid command&#39;)  # error message for invalid command
        current_room = current_room
    return current_room, inventory


while current_room != &#39;Bedchamber&#39;:  # while loop for gameplay
    player_instructions()
    print(&#39;You are in the {}.&#39;.format(current_room))

    if castle_rooms[current_room][&#39;Item&#39;] not in inventory:
        print(&#39;You see {} in the room.&#39;.format(castle_rooms[current_room][&#39;Item&#39;]))
    else:
        pass
    user_input = input(&#39;What will you do next?&#39;).split()
    command = user_input[0]
    direction = user_input[1] if len(user_input) &gt; 1 else &#39;&#39;
    current_room = player_commands(command, direction)

This is the entire code so far, everything worked until I tried adding a separate player inventory. I haven't added the game end code yet so I realize I have an infinite loop but I was trying to make the inventory work before I added the ending since the inventory has to include all items to win.

以下是翻译好的代码部分：

当你“拿取”一个物品时，你想要将其添加到你的物品清单中并从房间中移除它。

尝试类似这样的操作：

```python
    elif command == '拿取':
        current_item = castle_rooms[current_room_id]['物品']
        if current_item not in inventory:
            inventory.append(current_item)
            castle_rooms[current_room_id]['物品'] = None
            return current_room_id

如果你在大约第 56 行周围遇到错误（根据你的原始代码），可能是这样的：

    if castle_rooms[current_room]['物品'] not in inventory:
        print('你在房间里看到了{}。'.format(castle_rooms[current_room]['物品']))
    else:
        pass

如果一个房间没有物品，那么这将引发一个键错误。尝试将该代码替换为：

    current_room_item = castle_rooms[current_room].get('物品')
    if current_room_item not in inventory:
        print('你在房间里看到了{}。'.format(current_room_item))

这是一个更完整的示例：

import time

def player_instructions():
    # 主菜单和游戏命令
    print('移动命令:\n\t向北走, 向南走, 向西走, 向东走')
    print("物品命令:\n\t显示, 拿取")

def player_commands(command, direction):  # 用于移动房间的函数
    global current_room_id  # 声明当前房间为全局变量
    global inventory  # 声明物品清单为全局变量

    if command == '显示':
        if not inventory:
            print("你的背包是空的。")
            return current_room_id
        
        print("你有以下物品：")
        for item in inventory:
            print(f"    - {item}")
        return current_room_id

    if command == '拿取':
        current_item = castle_rooms[current_room_id]['物品']

        if not current_item:
            print("这里没有东西可拿")
            return current_room_id

        if current_item in inventory:
            print(f"你已经有了{current_item}")
            return current_room_id

        print(f"你贪婪地拿起了{current_item}")
        inventory.append(current_item)
        castle_rooms[current_room_id]['物品'] = None
        return current_room_id

    if command == '走':
        if direction not in castle_rooms[current_room_id]:
            print("你不能那样走")
            return current_room_id

        print(f"你向{direction}离开了{current_room_id}。")
        return castle_rooms[current_room_id][direction]

    print('无效的命令')  # 无效命令的错误消息
    return current_room_id

}
## -----------------------

current_room_id = '入口大厅'  # 定义起始房间
inventory = []  # 定义物品清单的字符串

print('-' * 50)
print('一场圣骑士的冒险游戏。')  # 游戏开场问候语
print('收集7个物品以赢得游戏，')
print('或被吸血鬼领主摧毁。')

while current_room_id != '卧室':  # 游戏玩法的循环
    current_room = castle_rooms[current_room_id]
    current_room_item = current_room['物品']
    current_room_exits = [key for key in current_room if key != "物品"]

    print('-' * 50)
    print(f'你在{current_room_id}。')
    print(f'可见的出口有：{current_room_exits}')
    if current_room_item:
        print(f'你看到了房间里的{current_room_item}。')
    player_instructions()

    command = input('你要做什么？ ')
    direction = None
    if " " in command:
        command, direction = command.split()

    current_room_id = player_commands(command, direction)
    time.sleep(2)

print("恭喜，你到达了卧室！")

英文:

When you "get" an item, you want to append it to your inventory and remove it from the room.

Try something like:

    elif command == &#39;get&#39;:
        current_item = castle_rooms[current_room_id][&#39;Item&#39;]
        if current_item not in inventory:
            inventory.append(current_item)
            castle_rooms[current_room_id][&#39;Item&#39;] = None
            return current_room_id

If you are getting an error around line 56 of so that is (based on your original code) likely:

    if castle_rooms[current_room][&#39;Item&#39;] not in inventory:
        print(&#39;You see {} in the room.&#39;.format(castle_rooms[current_room][&#39;Item&#39;]))
    else:
        pass

If a room does not have an item, then this will throw a key error. Try replacing that code with:

    current_room_item = castle_rooms[current_room].get(&#39;Item&#39;)
    if current_room_item not in inventory:
        print(&#39;You see {} in the room.&#39;.format(current_room_item ))

Here is a more complete example:

import time

def player_instructions():
    # main menu and game commands
    print(&#39;Move Commands:\n\tgo North, go South, go West, go East&#39;)
    print(&quot;Inventory Commands:\n\tshow, take&quot;)

def player_commands(command, direction):  # function for moving rooms
    global current_room_id  # declare current room as global
    global inventory  # declare inventory as global

    if command == &#39;show&#39;:
        if not inventory:
            print(&quot;Your backpack is empty.&quot;)
            return current_room_id
        
        print(&quot;You have the following items:&quot;)
        for item in inventory:
            print(f&quot;    - {item}&quot;)
        return current_room_id

    if command == &#39;take&#39;:
        current_item = castle_rooms[current_room_id][&#39;Item&#39;]

        if not current_item:
            print(f&quot;There is nothing here to take&quot;)
            return current_room_id

        if current_item in inventory:
            print(f&quot;You already have the {current_item}&quot;)
            return current_room_id

        print(f&quot;You greedily take the {current_item}&quot;)
        inventory.append(current_item)
        castle_rooms[current_room_id][&#39;Item&#39;] = None
        return current_room_id

    if command == &#39;go&#39;:

            print(&quot;You can&#39;t go that way&quot;)
            return current_room_id

        print(f&quot;You head {direction} out of the {current_room_id}.&quot;)

So I worked with a friend that knows python and he taught me some really neat new things, adding color to the code and he also helped me fix my inventory problems  I think the inline comments explain most of what is going on with it, I&#39;m so excited to have it working well.
```class TextColor:
    RED = &#39;\033[91m&#39;
    GREEN = &#39;\033[92m&#39;
    YELLOW = &#39;\033[93m&#39;
