# Repository Guidelines

## 项目结构与模块组织
本仓库是 `Cocos Creator 3.8.8` 小游戏项目。主入口在 `assets/main.ts`，主场景是 `assets/main.scene`。页面与弹窗组件集中在 `assets/prefabs/`，命名通常为 `PageXxx.ts`、`PassModal.ts`。公共逻辑位于 `assets/scripts/`：`core/` 放页面基类与视图管理，`utils/` 放 SDK、鉴权、存储、网络等工具，`config/` 放接口配置，`types/` 放类型定义。静态资源在 `assets/resources/`，编辑器配置在 `settings/v2/packages/`，设计说明在 `docs/` 与根目录分析文档中。

## 构建、调试与开发命令
先运行 `npm install`，同步 `minigame-api-typings` 依赖。日常开发主要通过 Cocos Creator 编辑器完成：使用 3.8.8 打开仓库，点击 `Play` 预览，使用 `Project > Build` 或 `Cmd+B` 构建小游戏包。若编辑器已生成 `temp/tsconfig.cocos.json`，可执行 `npx tsc --noEmit` 做一次 TypeScript 静态检查。

## 代码风格与命名约定
项目使用 TypeScript，当前代码统一为 4 空格缩进。组件类、页面类、管理器类使用 `PascalCase`，实例属性与私有方法使用 `camelCase` / `_camelCase`，管理器统一使用 `XxxManager` 后缀。新增页面、预制体、脚本请保持同名，例如 `PageLevel.prefab` 对应 `PageLevel.ts`。优先把复用逻辑放入 `assets/scripts/utils/` 或 `assets/scripts/core/`，不要把业务代码散落到场景脚本中。Cocos 资源的 `.meta` 文件必须一并提交。

## 测试与验证
仓库当前未配置 Jest、Vitest 一类自动化测试。提交前至少完成三项验证：1. 编辑器预览主流程可进入页面；2. 目标平台构建成功；3. 涉及微信能力时，在真机或开发者工具验证登录、分享、隐私授权等流程。若修改接口或体力/关卡逻辑，补充手动验证步骤到 PR 描述。

## 好友分享挑战链路
当前好友分享挑战是独立于普通闯关的一条链路，核心入口和数据流如下。

1. 选题入口在首页 `PageHome`，点击 `PK` 按钮后进入 `PageWriteLevels`，不是从普通 `PageLevel` 内发起。[assets/prefabs/PageHome.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageHome.ts#L153)
2. `PageWriteLevels` 会通过 `CompletedLevelsManager.fetch()` 拉取当前用户“已通关关卡”列表，只允许从这些题里选题；当前规则要求必须选满 `6` 关才能预览或正式创建分享。[assets/prefabs/PageWriteLevels.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageWriteLevels.ts#L140) [assets/prefabs/PageWriteLevels.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageWriteLevels.ts#L507)
3. 预览按钮只做本地预览：把 `selectedIndices` 和 `shareTitle` 传给 `PagePreviewLevels`，后者再从 `CompletedLevelsManager` 缓存中按索引读取答案、提示和封面图展示，不会请求后端。[assets/prefabs/PageWriteLevels.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageWriteLevels.ts#L525) [assets/prefabs/PagePreviewLevels.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PagePreviewLevels.ts#L108)
4. 正式分享时，`PageWriteLevels` 会把选中索引转成 `levelIds`，调用 `ShareManager.createShare(title, levelIds)` 命中 `POST /share` 创建挑战，服务端返回 `shareCode`。[assets/prefabs/PageWriteLevels.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageWriteLevels.ts#L536) [assets/scripts/utils/ShareManager.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/scripts/utils/ShareManager.ts#L53)
5. 创建成功后，页面会尝试补充一次发起者头像昵称信息，再调用 `WxSDK.shareAppMessage` 发起微信转发；真正落到分享卡片上的关键信息只有标题和 `query=shareCode=xxx`，没有把题目内容塞进 query。[assets/prefabs/PageWriteLevels.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageWriteLevels.ts#L563) [assets/scripts/utils/ShareManager.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/scripts/utils/ShareManager.ts#L219)
6. 被分享用户从微信卡片进入小游戏时，启动页 `PageLoading` 通过 `WxSDK.getShareCodeFromLaunch()` 读取启动参数。如果拿到 `shareCode` 且登录成功，会先调用 `ShareManager.joinShare(code)` 命中加入分享接口，再跳过首页直接打开 `PageLevel`，并带上 `params.shareMode = true`。[assets/PageLoading.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/PageLoading.ts#L82) [assets/scripts/utils/WxSDK.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/scripts/utils/WxSDK.ts#L302)
7. `ShareManager.joinShare()` 会把服务端返回的分享关卡列表转成运行时 `RuntimeLevelConfig[]`，缓存到内存里；这里不会再走普通闯关的 `AuthManager.nextLevel` / `LevelDataManager` / `enterLevel` 链路，首关图片会被预加载，后续关卡按需懒加载。[assets/scripts/utils/ShareManager.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/scripts/utils/ShareManager.ts#L73) [assets/scripts/utils/ShareManager.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/scripts/utils/ShareManager.ts#L150)
8. `PageLevel` 在 `shareMode` 下会把 `_shareLevelIndex` 置为 `0`，进入 `_enterAndInitLevel()` 时直接从 `ShareManager.ensureShareLevelReady(index)` 取当前题配置，跳过普通模式里的 `StaminaManager.enterLevel()`，因此分享挑战不消耗体力，也不依赖普通闯关的 enter 接口回填答案和提示。[assets/prefabs/PageLevel.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageLevel.ts#L258) [assets/prefabs/PageLevel.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageLevel.ts#L330)
9. 分享挑战里的作答判定仍然完全在 `PageLevel.onSubmitAnswer()` 本地完成，即把用户输入与当前 `config.answer` 做字符串相等比较；答对后走成功弹窗和下一题，答错后走错误弹窗。[assets/prefabs/PageLevel.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageLevel.ts#L1504)
10. 分享模式通关后只会上报 `POST /share/progress`，参数是 `shareCode + levelId + passed + timeSpent`。当前代码只在答对时调用，超时和答错不会上报失败结果，所以服务端拿到的是“成功通关进度”，不是完整作答事件流。[assets/prefabs/PageLevel.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageLevel.ts#L1566) [assets/scripts/utils/ShareManager.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/scripts/utils/ShareManager.ts#L187)
11. 分享模式切下一题时只是 `_shareLevelIndex++`，直到分享题单做完后清掉 `ShareManager` 的内存态并 `replace('PageHome')` 返回首页。中途从超时弹窗回首页，也会先清理分享态。[assets/prefabs/PageLevel.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageLevel.ts#L1831) [assets/prefabs/PageLevel.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageLevel.ts#L1880)

## 已知约束与缺口
1. `PageLevel` 的分享模式标题显示的是“第 1 关、第 2 关”这种分享内序号，不是原题库真实关卡号。[assets/prefabs/PageLevel.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageLevel.ts#L1004)
2. `PassModal` 和 `TimeoutModal` 里的分享按钮仍然发的是普通 `level=...` query，不是 `shareCode` 挑战链路；这两处分享目前不能把用户重新带回当前好友挑战，只是普通分享文案。[assets/prefabs/PassModal.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PassModal.ts#L453) [assets/prefabs/TimeoutModal.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/TimeoutModal.ts#L136)
3. `ShareManager.joinShare()` 构造 `RuntimeLevelConfig` 时没有填 `timeLimit`，而 `PageLevel` 会用 `config.timeLimit ?? 60` 兜底，所以分享题当前统一按 60 秒处理，除非后端后续补字段、前端同步接入。[assets/scripts/utils/ShareManager.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/scripts/utils/ShareManager.ts#L91) [assets/prefabs/PageLevel.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageLevel.ts#L416)
4. `PagePreviewLevels` 和 `PageWriteLevels` 的选题/预览都依赖“索引对应同一份 completed list”的前提。如果列表数据在两个页面生命周期之间发生变化，按索引取题会有错位风险，更稳妥的做法其实是直接传 `levelIds` 或完整快照。[assets/prefabs/PageWriteLevels.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PageWriteLevels.ts#L528) [assets/prefabs/PagePreviewLevels.ts](/Users/richard/Documents/code/cocosProject/mp-xieyingeng/assets/prefabs/PagePreviewLevels.ts#L192)
