MUD Adventure Skill

文字冒险型 MUD 游戏创作技能包。帮你从零构建可运行的单文件 Python MUD 游戏。

快速开始

游戏核心只需一个 Python 文件（game.py），运行方式：

python game.py

首次使用，按以下流程构建游戏：

世界观设计 → 地图建模 → 人物/物品 → 对话/任务 → 合并到 game.py

详细设计指南见 references/world-design.md（世界观、故事结构） 详细系统指南见 references/game-systems.md（战斗、物品、任务） 示例代码见 references/examples.md

默认游戏模板

以下模板可直接复制到 game.py 运行，内含 3 个房间、1 个 NPC、1 个战斗场景：

扩展指南

添加新房间

在 rooms 字典中新增键值对，定义 name、desc、exits、items、npcs。

添加新 NPC

在 npcs 字典中定义，设置 name、desc、hp、attack、dialogue、hostile。

添加新物品

在 items 字典中定义，设置 name、desc、effect（None/heal/power/custom）。

添加战斗系统

参考 references/game-systems.md 中的战斗系统设计，可扩展：经验值、等级、怪物掉落、魔法技能。

添加任务系统

参考 references/game-systems.md 中的任务系统，用 player["flags"] 跟踪任务进度。
