Python游戏Gym场景物品无法拾取问题求助（附代码）

修改代码后，房间物品显示、移动功能均正常，但进入Gym场景尝试拾取物品时，会输出“找不到该物品”的提示，且每次尝试修复都会导致其他功能损坏。

原代码：

def clear():
    os.system('cls' if os.name == 'nt' else 'clear')


# dictionary
rooms = {
    'Locker Room': {'South': 'Dressing Room'},  # starting room
    'Dressing Room': {'East': 'Ring', 'North': 'Locker Room', 'Item': 'Rics Robe'},
    'Ring': {'North': 'Gym', 'South': 'Steel Cage', 'West': 'Dressing Room', 'East': 'Office', 'Item': 'Chair'},
    'Gym': {'South': 'Ring', 'East': 'Garage', 'Item': 'RKO Promo'},
    'Garage': {'West': 'Gym', 'Item': 'Blueprint'},
    'Steel Cage': {'North': 'Ring', 'East': 'Green Room', 'Item': 'Mr.Socko'},
    'Green Room': {'West': 'Steel Cage', 'Item': 'StoneCold Beer'},
    'Office': {'West': 'Ring', 'Boss': 'Vance McMan'}  # villain


}

# list of vowels
vowels = ['a', 'e', 'i', 'o', 'u']

# directions
direction = ['north', 'south', 'east', 'west']

# track inventory
inventory = []

# track the current room
current_room = 'Locker Room'

Item = rooms[current_room].get('Item')
# results of the players previous move
msg = ''

clear()
prompt()

# gameplay loop until exit
while True:
    clear()
    # display info to player
    print(f"You are in the {current_room}\nInventory : {inventory}\n{' - ' * 27}")

    # display the msg
    print(msg)

    # indicate items
    if 'Item' in rooms[current_room].keys():
        nearby_item = rooms[current_room]["Item"]

        if nearby_item not in inventory:

            if nearby_item[-1] == 's':
                print(f'You see {nearby_item}')

            elif nearby_item[0] in vowels:
                print(f'You see an {nearby_item}')

            else:
                print(f'You see a {nearby_item}')

    # boss encounter
    if 'Boss' in rooms[current_room].keys():
        # lose
        if len(inventory) < 6:
            print(f"Game over! You lost a fight with {rooms[current_room]['Boss']}")

        # win
        else:
            print(f"You beat {rooms[current_room]['Boss']}")

    # accept the player move as input
    move = input('Which direction will you go?\n')

    # split the move into words
    next_move = move.split(' ')

    # the first word is an action
    action = next_move[0].title()

    if len(next_move) > 1:
        Item = next_move[1:]
        direction = next_move[1].title()

        Item = ' '.join(Item).title()

    # move in between rooms
    if action == 'Go':
        try:
            current_room = rooms[current_room][direction]
            msg = f'You go {direction}.'

        except:
            msg = f'You cannot go that way.'

    # picking up items
    elif action == "Get":
        if Item == rooms[current_room]['Item']:

            if Item not in inventory:
                inventory.append(rooms[current_room]['Item'])
                msg = f"{Item} retrieved!"

            else:
                msg = f"You already have the {Item} in your inventory."

        else:
            msg = f"Cannot find the {Item}"

    # exit the game
    if move == 'Exit':
        current_room = 'exit'
        print('Game over. Thank you for playing!')
        break

    # any other commands invalid
    else:
        msg = f"Invalid command"

问题原因 #

1. 大小写不匹配：处理物品名称时使用.title()将其转为每个单词首字母大写（如输入Get RKO Promo会被转为Rko Promo），但房间中存储的物品名是RKO Promo（RKO全大写），导致两者比对不相等，触发“找不到物品”提示。
2. 全局变量被覆盖：全局direction列表被错误赋值为物品名称的一部分，虽未直接影响拾取，但存在功能隐患。
3. 逻辑分支顺序错误：Exit的独立if语句与后续else配对，会覆盖Get/Go分支设置的提示信息。

修复后的代码 #

import os

def clear():
    os.system('cls' if os.name == 'nt' else 'clear')


# 房间配置
rooms = {
    'Locker Room': {'South': 'Dressing Room'},  # 初始房间
    'Dressing Room': {'East': 'Ring', 'North': 'Locker Room', 'Item': 'Rics Robe'},
    'Ring': {'North': 'Gym', 'South': 'Steel Cage', 'West': 'Dressing Room', 'East': 'Office', 'Item': 'Chair'},
    'Gym': {'South': 'Ring', 'East': 'Garage', 'Item': 'RKO Promo'},
    'Garage': {'West': 'Gym', 'Item': 'Blueprint'},
    'Steel Cage': {'North': 'Ring', 'East': 'Green Room', 'Item': 'Mr.Socko'},
    'Green Room': {'West': 'Steel Cage', 'Item': 'StoneCold Beer'},
    'Office': {'West': 'Ring', 'Boss': 'Vance McMan'}  # 最终Boss
}

# 元音列表
vowels = ['a', 'e', 'i', 'o', 'u']

# 有效方向（保留全局列表，不被覆盖）
valid_directions = ['north', 'south', 'east', 'west']

# 玩家背包
inventory = []

# 当前房间
current_room = 'Locker Room'

# 上一步操作提示
msg = ''

clear()
# prompt()  # 原代码未定义该函数，暂注释

# 游戏主循环
while True:
    clear()
    # 显示当前状态
    print(f"You are in the {current_room}\nInventory : {inventory}\n{' - ' * 27}")
    print(msg)

    # 显示当前房间物品
    if 'Item' in rooms[current_room]:
        nearby_item = rooms[current_room]["Item"]
        if nearby_item not in inventory:
            if nearby_item[-1] == 's':
                print(f'You see {nearby_item}')
            elif nearby_item[0].lower() in vowels:
                print(f'You see an {nearby_item}')
            else:
                print(f'You see a {nearby_item}')

    # Boss遭遇战
    if 'Boss' in rooms[current_room]:
        if len(inventory) < 6:
            print(f"Game over! You lost a fight with {rooms[current_room]['Boss']}")
        else:
            print(f"You beat {rooms[current_room]['Boss']}")

    # 获取玩家输入
    move = input('Which direction will you go?\n').strip()
    msg = ""
    next_move = move.split()

    if not next_move:
        msg = "Invalid command"
        continue

    action = next_move[0].title()

    # 处理移动命令
    if action == 'Go':
        if len(next_move) < 2:
            msg = "Please specify a direction (North/South/East/West)"
            continue
        go_direction = next_move[1].title()
        if go_direction in rooms[current_room]:
            current_room = rooms[current_room][go_direction]
            msg = f'You go {go_direction}.'
        else:
            msg = f'You cannot go that way.'
    # 处理拾取命令
    elif action == "Get":
        if len(next_move) < 2:
            msg = "Please specify an item to get"
            continue
        requested_item = ' '.join(next_move[1:])
        room_item = rooms[current_room].get('Item', '')
        # 忽略大小写比对，避免大小写问题
        if requested_item.lower() == room_item.lower():
            if room_item not in inventory:
                inventory.append(room_item)
                msg = f"{room_item} retrieved!"
            else:
                msg = f"You already have the {room_item} in your inventory."
        else:
            msg = f"Cannot find the {requested_item}"
    # 处理退出命令
    elif move.lower() == 'exit':
        print('Game over. Thank you for playing!')
        break
    # 无效命令
    else:
        msg = "Invalid command"

修复要点 #

1. 补上缺失的import os，注释未定义的prompt()函数。
2. 将全局direction列表改名为valid_directions，避免被错误覆盖。
3. 拾取物品时采用忽略大小写的比对逻辑，解决物品名大小写不匹配问题。
4. 调整逻辑分支结构，将Exit命令纳入elif分支，避免覆盖其他操作的提示信息。
5. 增加输入为空、参数缺失的判断，优化错误提示逻辑。
6. 每次循环重置msg，避免上一次操作的提示残留。
