文本冒险游戏拾取物品后房间物品未删除的技术问题

你的核心问题是拾取物品的逻辑仅将物品添加到玩家背包，但未同步更新房间的物品状态，且原代码中删除房间物品的逻辑位置错误，导致只有输入非grab指令时才会尝试修改房间状态，完全不符合需求。

问题分析 #

• 拾取物品时仅执行inventory.append()，未修改房间内的item字段，导致show_status()始终显示原有物品。
• 原代码中删除房间物品的代码位于direction_input != 'grab'的分支中，逻辑完全颠倒。

修复方案 #

在成功将物品添加到玩家背包后，立即将当前房间的item字段设置为'Nothing'（与初始无物品房间的状态保持一致），确保show_status()能正确显示房间已无物品。同时调整指令判断顺序，避免逻辑冲突。

rooms = {  # 创建房间字典
    'Center of the Village': {'go north': "Village Scribe", 'go south': "Mage Tower", 'go east': 'Village Dining Hall',
                              'go west': 'Village Tailor', 'item': 'Nothing'},
    'Village Scribe': {'go east': 'Bridge to the Castle', 'go south': 'Center of the Village', 'item': 'The Monster Hunting Guidebook'},
    'Mage Tower': {'go north': 'Center of the Village', 'go east': 'Mage Library', 'item': 'The Magic Staff'},
    'Village Dining Hall': {'go north': 'Village Elders', 'go west': 'Center of the Village', 'item': 'The Hearty Stew'},
    'Village Tailor': {'go east': 'Center of the Village', 'item': 'The Magic Cloak'},
    'Village Elders': {'go south': 'Village Dining Hall', 'item': 'The Amulet of Protection'},
    'Mage Library': {'go west': 'Mage Tower', 'item': 'The Spell Caster Scrolls'},
    'Bridge to the Castle': {'go west': 'Village Scribe', 'item': 'The Bridge Troll'}

        else:
            inventory.append(current_item)
            rooms[current_room]['item'] = 'Nothing'
            print(f'You grabbed {current_item}!')
        continue  # 处理完拾取后直接进入下一轮循环

    # 处理移动指令
    if direction_input in rooms[current_room]:
        current_room = move_rooms(current_room, direction_input)

        if direction_input not in commands:
            print('Invalid move.\n')
        else:
            print(f'You can not go that way.')
        print('---------------------------\n')

修复说明 #

1. 重构grab指令逻辑：成功拾取物品后立即将房间的item设为'Nothing'，确保房间状态同步更新。
2. 调整指令判断顺序：先处理exit和grab指令，再处理移动操作，避免逻辑冲突。
3. 移除原代码中错误位置的物品删除逻辑，避免因误删字典键导致报错。
