文本游戏中While循环内If条件无法终止循环的问题求助

先梳理你代码里的核心问题，再给出修正后的完整实现：

核心问题点 #

1. 目标物品列表不全：你定义的物品列表只包含5个物品，漏掉了Religious Shrine里的Dagger Sheath，永远凑不齐要求的6个
2. 女王密室无进入校验：当前代码允许玩家直接进入最终房间，没有检查物品收集情况
3. 数量判断逻辑错误：len(inventory) == '6'是字符串和整数的无效比较，永远不会成立
4. 拾取命令匹配过严：必须严格输入Take [物品全称]（含大小写），玩家输入稍有偏差就失效

修正后的完整代码 #

rooms = {'Jail Cell': {'name': 'Jail Cell', 'South': 'Barracks',
                       'text': 'You\'re in the Jail Cell.', 'item': 'whole lot of nothing'},
         'Barracks': {'name': 'the Barracks', 'West': 'Dining Hall', 'North': 'Jail Cell',
                      'text': 'You\'re in the Barracks.', 'item': 'Strange Potion'},
         'Dining Hall': {'name': 'the Dining Hall', 'West': 'Queens Chamber', 'North': 'Alchemist Room',
                         'South': 'Bedchamber', 'East': 'Barracks',

        print('You win!')
        break

    # 无效命令提示
    else:
        print('Invalid input. Review the instructions!')

关键修改说明 #

1. 补全必备物品列表：加入Dagger Sheath，确保是要求的6个物品
2. 新增最终房间校验：玩家试图进入女王密室时，用all()检查是否收集全所有物品，未收集全则阻止进入并提示
3. 优化拾取逻辑：支持大小写容错，拆分命令提取物品名，避免严格匹配导致的无效操作
4. 修复结局触发：只有成功进入最终房间后才触发结局并终止循环，符合游戏逻辑
