一个在浏览器里运行的实时武侠动作游戏 —— 全部代码由 Claude Opus 5.5 编写，第一版在一天一夜里完成
A real-time wuxia action game in the browser. Every line of code written by Claude Opus 5.5 — the first playable version in about a day.
一名剑客，三章旅程，纯 three.js / WebGL，打开网页就能玩，不需要安装。
| 章 | 场景 | Boss |
|---|---|---|
| 一 · 长风 | 黄昏逆光的金色草原，风吹草浪，孤树与石碑 | 断刀客 |
| 二 · 竹林夜雨 | 雨夜竹林，闪电、积水倒影、石灯笼 | 夜枭（会隐身闪现的刺客） |
| 三 · 长街灯火 | 江南古镇长街，五百盏灯笼，河道石桥，会惊慌躲避的市民 | 寒山客 · 戏台前决战 |
战斗：轻重连击、格挡与完美弹反、闪避无敌帧、架势崩溃与处决、剑气、击飞击倒、锁定、弓手/盾兵/枪兵/刺客等不同敌人。
我没有写代码。 我只用中文向 Claude Code（Opus 5.5）描述想要什么、试玩、提意见；设计、编码、调试、测试、性能优化都由 AI 完成。Opus 5.5 作为总负责，把工作拆给多个并行的子代理（地形、草、天空、角色、战斗、音频、UI……），用一份接口契约（CONTRACTS.md）和美术圣经（docs/BIBLE.md）让它们协同，再亲自集成、截图验收、返工。
真实时间线（北京时间，来自会话记录）：
| 时间 | 进展 |
|---|---|
| 9/24 17:29 | 第一条提示："用 three.js 参考这个网站的视觉效果，实现一个剑客在草原上战斗的游戏，要求极致的逼真，极致的美学设计" |
| 9/24 晚 | 草原、草浪、天空、后期管线、程序化角色、战斗系统、敌人波次 —— 第一个可玩版本 |
| 9/24 深夜 – 9/25 凌晨 | 反复打磨剑客动作；从一段中国剑演示视频中提取姿态做动作捕捉并重定向到骨骼 |
| 9/25 上午 | 用 Tripo AI 生成角色模型与动画并接入；跳斩、空中翻滚斜劈等招式；第一轮性能优化；敌人模型 |
| 9/25 中午 | 打击感：顿帧、震屏、方向受击、击飞击倒、合成打击音效和喊杀声；逐个角色排查不自然动作 |
| 9/25 下午 | 画质档位、TAA 超分辨率、找出 GC 卡顿根因；关卡系统 + 第二章「竹林夜雨」+ Boss 夜枭 |
| 9/25 21:12 | 第三章「长街灯火」：古镇、河道、市民 AI，第一版完成 |
| 9/26 上午 | 开源，部署在线试玩 |
| 9/27 凌晨 – 上午 | 接入 Mixamo 动作捕捉（主角、全部敌人、市民）；手臂与手腕的解剖修正、空中脚型；手机 / 平板触屏操作 |
第一版合计墙钟约 28 小时，其中 AI 实际工作约 19 小时；之后仍在继续打磨。

人做了什么：提出方向和审美要求、试玩并指出哪里不自然、录了一段参考视频、登录 Tripo 账号并授权 AI 使用额度、登录 Mixamo 账号供 AI 下载动作。
| 键 | 动作 | 键 | 动作 | |
|---|---|---|---|---|
| WASD | 移动 | 鼠标左键 | 斩（按住：重击） | |
| 鼠标 | 视角 | 鼠标右键 | 格挡（命中瞬间：弹反） | |
| Space | 闪避 | Shift | 疾跑 | |
| Q / Tab | 锁定 | E | 剑气 | |
| F | 拔剑 / 收剑 | Esc | 暂停（可切换画质与章节） |
手机 / 平板：触屏设备自动显示水墨风格的虚拟按键 —— 左手拇指在屏幕左侧任意位置按下即出现摇杆（推过外圈为疾跑），右侧空白处滑动转视角；右下角：斩（按住蓄力重击）、闪、格（命中瞬间按下弹反）、气、锁、剑，右上角暂停。建议横屏游玩。?touch=1 强制显示，?touch=0 关闭。
录屏模式：H 隐藏界面 · O 环绕运镜 · T 慢动作。
常用网址参数：?level=steppe|bamboo|town 选章 · ?demo=1 AI 自动战斗（适合录素材）· ?hud=0 无界面 · ?q=low|med|high 画质。

Long Wind is a third-person wuxia action game running in the browser (three.js / WebGL, no install). Three chapters — a golden-hour steppe, a bamboo forest in a night storm, and a lantern-lit canal town full of townsfolk who scatter when swords are drawn — with light/heavy combos, parries, dodges, posture breaks and executions, launches and knockdowns, and five enemy types plus bosses.
No human wrote the code. The author described what they wanted in Chinese, played the builds, and gave feedback; Claude Opus 5.5 in Claude Code did the design, code, debugging, tests and performance work, coordinating parallel sub-agents through an interface contract (CONTRACTS.md) and an art bible (docs/BIBLE.md). From the first prompt (Sep 24, 17:29 CST) to the third chapter (Sep 25, 21:12 CST): ~28 hours wall clock, ~19 hours of active agent time for the first version; polishing continued afterwards (motion capture, anatomical arm fixes, touch controls).
Phones and tablets get on-screen ink-brush controls: a floating left thumb-stick (push past the rim to sprint), drag on the right to look, and a fan of 斩 strike (hold: heavy) · 闪 dodge · 格 block/parry · 气 sword qi · 锁 lock · 剑 draw buttons; landscape recommended (?touch=1 forces them, ?touch=0 hides them).
Record mode: H hides the HUD, O orbit camera, T slow motion. URL: ?level=steppe|bamboo|town, ?demo=1 (AI plays), ?hud=0, ?q=low|med|high.
