如何在Replit平台实现Python文字冒险游戏的存档与读档功能

核心实现思路 #

• 采用单个JSON文件存储全部游戏进度，替代分散的多个txt文件，统一管理状态更方便
• 存档内容包含：玩家名称、当前所处的游戏阶段、背包数据、XP值、饥饿值、口渴值全部核心状态
• 游戏启动时自动检测存档文件存在性，询问用户是否加载存档
• 每完成一个关键选择后自动触发存档，不需要用户手动操作，避免进度丢失

完整修改后代码 #

功能说明 #

• 每次玩家完成选择后会自动存档，退出游戏后下次启动会主动询问是否加载进度
• 所有状态包括背包内容、属性值、当前游戏节点都会完整保存，读取后直接从断点继续
• 兼容中英文输入选择，降低玩家操作门槛
