def _tutorial_md(game):
    return f"""# 把「{game}」素材接进 Cocos —— 零基础教程

这个文件夹是你点「导出 Cocos 整合包」自动生成的，可以直接进 Cocos Creator。
全程不用写代码：装软件 → 新建项目 → 拖文件 → 挂一个脚本 → 点播放。

## 包里有什么
```
cocos-pack/
├─ 本教程.md
└─ assets/                         ← 整个拖进 Cocos
   ├─ resources/characters/  角色三件套（.json/.atlas/.png）
   ├─ resources/vfx/         粒子配置 .json + particle.png
   └─ scripts/  JellyDemo.ts / ParticleConfig.ts / TweenPresets.ts
```
> `resources` 文件夹名不能改，Cocos 靠它动态加载资源。

## 步骤
1. 装 **Cocos Creator 3.8.x**：https://www.cocos.com/creator-download
2. 新建一个 **空项目（Empty / 2D）** 并打开。
3. 把本包 `assets/` 里的 **resources、scripts 两个文件夹**一起拖进 Cocos 资源管理器的 `assets` 上，等导入进度条走完。
4. 在 `assets` 右键 → 新建 Scene，双击打开；确保有个 **Canvas** 节点，在它下面新建一个**空节点**。
5. 把 `scripts/JellyDemo.ts` 拖到那个空节点的属性检查器上（或「添加组件 → JellyDemo」）。
6. 点正上方 **▶ 播放**：角色排队果冻抖动，底部按钮可触发「全部 WIN」和各粒子特效。

## 常见问题
- 角色没出来：多半素材没导完或 resources 被改名；确认能在资源管理器把角色展开成 SkeletonData。
- 角色发黑/白边：脚本已设 premultipliedAlpha=false；仍有则在贴图设置关掉 PremultiplyAlpha 重新导入。
- 太大/太小：改 `JellyDemo.ts` 顶部 `CHAR_SCALE`。
- 特效看不见：确认 `resources/vfx/particle.png` 在。
