+## 实现路线
+
+### P0 MVP — 最小可玩原型（3-5 天）✅ 已完成 2026-06-07
+
+目标：能播放一段视频 → 弹出选项 → 跳到下一段视频
+
+- [x] 项目脚手架：Vite + Vue3 + TypeScript + Pinia
+- [x] `engine/core/Engine.ts` — 主循环骨架（加载场景 → 播放 → 等选择 → 切换）
+- [x] `engine/core/SceneManager.ts` — 加载 JSON，按 ID 查找场景节点
+- [x] `engine/core/VideoManager.ts` — 单 video 元素播放，监听 ended 事件
+- [x] `engine/core/StateManager.ts` — 变量存取、条件求值、效果执行
+- [x] `engine/types.ts` — 类型定义
+- [x] `src/components/GamePlayer.vue` — 挂载 video，控制播放
+- [x] `src/components/ChoicePanel.vue` — 渲染选择按钮，触发引擎切换
+- [x] `public/scenes/demo.json` — 编写一段简单剧情（7 个场景节点）
+- [x] 验证：从 demo.json 加载场景，能走通 开始→选择→分支播放→结束 流程
+
+### P1 核心 — 无缝切换 + 条件分支 + 存档（1-2 周）
+
+- [ ] `engine/core/VideoManager.ts` 升级 — A/B 双缓冲，预加载候选视频，CSS 交叉淡化
+- [ ] `engine/core/SceneManager.ts` 升级 — 支持条件分支（根据 variables/flags 过滤选项）
+- [ ] `engine/systems/SaveSystem.ts` — Dexie.js IndexedDB 存取，多槽位
+- [ ] `engine/systems/ChoiceSystem.ts` — 限时选择倒计时，超时默认选择（第一项或配置的默认项）
+- [ ] `src/components/SaveLoadMenu.vue` — 存档/读档 UI
+- [ ] `src/stores/gameStore.ts` — Pinia 全局状态管理
+- [ ] `src/composables/` — 三个 composable 桥接层
+- [ ] 验证：分支剧情走通，存档读档正常，视频切换无明显黑屏
+
+### P2 进阶 — QTE + 字幕 + 多存档槽（1 周）
+
+- [ ] `engine/systems/QTESystem.ts` — QTE 触发、键盘监听、超时判定
+- [ ] `src/components/QTEOverlay.vue` — QTE 视觉遮罩（按键提示 + 倒计时环）
+- [ ] `src/components/Subtitles.vue` — WebVTT 解析 + 字幕渲染
+- [ ] 多存档槽位 + 存档缩略图（canvas 截图当前视频帧）
+- [ ] `engine/core/Engine.ts` — 完整事件总线（sceneChange, choiceMade, qteTriggered 等）
+- [ ] 验证：QTE 正常触发与判定，字幕同步，多存档正常工作
+
+### P3 编辑器 — 可视化剧情编辑（2-3 周）
+
+- [ ] 编辑器入口：独立 `editor/index.html` + `editor/main.ts`
+- [ ] `editor/components/SceneGraph.vue` — Vue Flow 节点图（节点=场景，边=选择分支）
+- [ ] `editor/components/NodeEditor.vue` — 右侧面板，编辑选中节点的视频、选项、QTE、条件/效果
+- [ ] `editor/components/PreviewPanel.vue` — 嵌入播放器，实时预览当前编辑的剧情线
+- [ ] `editor/composables/useGraphEditor.ts` — 图数据与 JSON 双向同步
+- [ ] JSON 导出/导入
+- [ ] 验证：编辑器能产出合法 JSON，引擎能正确加载并运行
+
+## 依赖清单
+
+```json
+{
+  "dependencies": {
+    "vue": "^3.4",
+    "pinia": "^2.1",
+    "@vue-flow/core": "^1.x",
+    "@vue-flow/background": "^1.x",
+    "@vue-flow/controls": "^1.x",
+    "dexie": "^4.0"
+  },
+  "devDependencies": {
+    "@vitejs/plugin-vue": "^5.0",
+    "typescript": "^5.3",
+    "vite": "^5.0",
+    "vue-tsc": "^2.0"
+  }
+}
+```
+
+## 关键架构决策记录
+
+1. **引擎与 UI 分离**: `engine/` 下纯 TS 类，不 import Vue。UI 层通过 composables 桥接。
+2. **A/B 双缓冲**: 两个 `<video>` 元素轮换，一个播放时另一个预加载候选视频。
+3. **JSON 驱动**: 所有剧情数据放在 JSON 中，编辑器本质是 JSON 的可视化读写工具。
+4. **IndexedDB 存档**: 比 localStorage 容量大，可存储截屏缩略图。

+交互式电影游戏的游戏引擎怎么制作

+
+## Assistant (Plan · DeepSeek V4 Pro · 116.1s)
+
+_Thinking:_
+
+The user is asking about how to create a game engine for an interactive movie game (交互式电影游戏). This is a high-level conceptual question, not related to any specific codebase. Let me think about this carefully.
+
+An interactive movie game (like Black Mirror: Bandersnatch, Late Shift, The Complex, or games by Quantic Dream like Detroit: Become Human) is essentially a game where players make choices at decision points that branch the narrative.
+
+Let me think about the key components of an interactive movie game engine:
+
+1. **Video Playback System** - Playing video clips seamlessly
+2. **Branching Narrative System** - Decision trees that lead to different video segments
+3. **Choice/Decision UI** - Presenting options to the player at decision points
+4. **State Management** - Tracking what choices were made, character relationships, etc.
+5. **Seamless Transitions** - Smooth transitions between video clips
+6. **Save/Load System** - Persisting game state
+
+Let me ask the user some clarifying questions since this is a very broad topic. But first, let me think about what aspects they might be asking about:
+
+- Are they asking about the technical architecture?
+- Which platform/language?
+- Are they looking for a specific implementation?
+
+Since we're in "Plan Mode" (read-only), I should discuss and plan rather than implement. Let me ask some clarifying questions.
+
+Actually, the user simply asked "交互式电影游戏的游戏引擎怎么制作" - "How to make a game engine for interactive movie games". This is quite broad. Let me provide a comprehensive plan/overview and ask clarifying questions.
+
+Let me think about the core architecture:
+
+**Core Architecture of an Interactive Movie Game Engine:**
+
+1. **Video Engine Layer**
+   - Video decoder/player (FFmpeg, libvlc, or platform-native)
+   - Seamless looping and preloading
+   - Multiple video track support (for different quality levels)
+   - Subtitle overlay support
+
+2. **Narrative/Dialogue Engine**
+   - Decision tree / directed graph data structure
+   - Scene/Chapter management
+   - Conditional branching based on state variables
+   - Timeline management
+
+3. **State Machine**
+   - Player choice history
+   - Character relationship values
+   - Global flags and variables
+   - Checkpoint system
+
+4. **UI Layer**
+   - Choice presentation (buttons, timed choices)
+   - QTE (Quick Time Events) overlay
+   - HUD elements
+
+5. **Asset Pipeline**
+   - Script/scenario authoring tool
+   - Video encoding pipeline
+   - Asset bundling
+
+**Technology Choices:**
+- **Unity + AVPro Video** or similar - good for cross-platform
+- **Unreal Engine** - good for high-end graphics
+- **Custom engine with FFmpeg/libvlc** - full control
+- **Web-based (HTML5 video + JavaScript)** - accessible
+
+Let me ask the user some clarifying questions to narrow this down.
+
+制作交互式电影游戏引擎可以从多个维度切入。在给出具体方案前，先确认几个关键方向：

+## Assistant (Plan · DeepSeek V4 Pro · 63.1s)
+
+_Thinking:_
+
+Good, the user wants:
+- **Web tech stack** (HTML5/JS)
+- **All 6 core features**: branching narrative, editor/scripting tools, save/load, seamless video switching, character relationship/state system, QTE
+- **Target: Web browser**
+
+Now let me design a comprehensive plan for building this interactive movie game engine.
+
+Let me think about the architecture:
+
+## Architecture Plan
+
+### 1. Core Engine Architecture (JavaScript/TypeScript)
+
+**Scene Graph / Narrative Engine:**
+- A directed graph where nodes are scenes (video clips) and edges are player choices
+- JSON-based scene definition format
+- Support for conditional branching based on state variables
+
+**Video Manager:**
+- Preload next possible videos while current one is playing
+- Seamless transition by having hidden video elements pre-buffered
+- Handle video end events to trigger choice UI
+
+**State Manager:**
+- Global state object tracking all variables
+- Character relationship scores
+- Choice history
+- Flags for conditional content
+
+**QTE System:**
+- Timed UI overlays during video playback
+- Success/failure branches
+
+**Save/Load:**
+- localStorage or IndexedDB for browser
+- Serialize/deserialize game state + current scene position
+
+### 2. Project Structure

+
+### 3. Scene Data Format (JSON Schema)
+
+```json
+{
+  "scenes": {
+    "scene_001": {
+      "id": "scene_001",
+      "video": "assets/videos/scene_001.mp4",
+      "subtitles": "assets/subtitles/scene_001.vtt",
+      "choices": [
+        {
+          "id": "choice_a",
+          "text": "打开左边的门",
+          "targetScene": "scene_002a",
+          "conditions": { "courage": { ">=": 5 } },
+          "effects": { "courage": "+2", "flags": ["opened_left_door"] }
+        },
+        {
+          "id": "choice_b", 
+          "text": "打开右边的门",
+          "targetScene": "scene_002b"

+    }
+  },
+  "startScene": "scene_001",
+  "variables": {
+    "courage": 0,
+    "trust": 50
+  }
+}
+```
+
+### 4. Key Technical Details
+
+**Seamless Video Switching:**
+- Use dual `<video>` elements (A/B buffering)
+- When choice is made, start playing the selected next video
+- Use CSS transitions to crossfade or use requestAnimationFrame for smooth switch
+- Preload next N candidate videos (based on current scene's possible targets)
+
+**Video Preloading Strategy:**
+- When entering a scene, identify all possible next scenes
+- Preload them using `video.preload = "auto"` and `video.load()`
+- Manage a video cache pool (limit to ~3-4 videos to avoid memory issues)
+
+**State System:**
+- Simple key-value store with event emitters
+- Conditions: support comparisons (>, <, >=, <=, ==, !=)
+- Effects: support arithmetic and flag toggling
+
+**Save/Load:**
+- Save = serialize { currentScene, state, choiceHistory, timestamp }
+- Store in IndexedDB (larger storage than localStorage)
+- Support multiple save slots
+
+**Editor:**
+- Could be a simple web-based drag-and-drop graph editor
+- Or a text-based JSON editor with validation
+- Visual flow chart using a library like React Flow or plain Canvas/SVG
+
+### 5. Implementation Phases
+
+**Phase 1: MVP Core**
+- Scene player with single video playback
+- Choice system with simple buttons
+- JSON scene definitions
+- Basic state tracking
+
+**Phase 2: Advanced Features**
+- Seamless video switching with preloading
+- Conditional branching
+- QTE system
+- Save/Load
+
+**Phase 3: Polish & Tools**
+- Visual editor
+- Subtitle support
+- Multiple save slots
+- Performance optimization
+
+Let me present this plan to the user. I should be thorough but concise. Since we're in plan mode, I'll outline the plan and ask if they want to proceed.
+
+Actually wait, the user might be expecting me to just provide a comprehensive answer/text about how to build it, since this is a conceptual question. Let me provide a well-structured plan.
+
+Also, let me consider if there are existing open-source web-based interactive movie engines we could reference:
+- Twine (text-based, but narrative structure is relevant)
+- Ren'Py (Python, not web, but good reference for visual novel engines)
+- ink by Inkle (scripting language for narrative, has JS runtime)
+- There's no dominant open-source web interactive movie engine that I know of
+
+Let me present a comprehensive plan.
+
+明确了。基于你的需求（Web 技术栈、全功能、浏览器目标平台），以下是完整的技术方案：

+├── public/videos/             -- 视频资源
+└── index.html
+```
+
+### 三、关键技术方案
+
+#### 1. 无缝视频切换（A/B 双缓冲）
+
+```typescript
+// 核心思路：两个 <video> 元素轮换
+// - 当 A 在播放时，B 预加载下一个可能场景
+// - 切换时：B.play() + CSS opacity 交叉淡化
+class VideoManager {
+  activeSlot: 'A' | 'B';
+  videoA: HTMLVideoElement;
+  videoB: HTMLVideoElement;
+
+  preload(sceneIds: string[]) {
+    // 根据当前节点的出边，预加载所有可能的下一段视频
+  }
+
+  switchTo(sceneId: string) {
+    const nextSlot = this.activeSlot === 'A' ? this.videoB : this.videoA;
+    nextSlot.src = getVideoUrl(sceneId);
+    nextSlot.play();
+    // CSS transition: 当前视频淡出，下一段淡入
+    crossFade(this.activeVideo, nextSlot, 300); // 300ms 过渡
+    this.activeSlot = this.activeSlot === 'A' ? 'B' : 'A';
+  }
+}
+```
+
+#### 2. 剧情节点数据结构
+
+```typescript
+interface SceneNode {
+  id: string;
+  videoUrl: string;
+  subtitleUrl?: string;
+  choices?: Choice[];           // 分支选择
+  qte?: QTEDefinition;         // QTE 事件
+  nextScene?: string;          // 无选择时的默认下一段
+  onEnter?: Effect[];          // 进入场景时触发的效果
+}
+
+interface Choice {
+  text: string;
+  targetScene: string;
+  conditions?: Condition[];    // 前置条件（关系值、flag 等）
+  effects?: Effect[];          // 选择后的后续效果
+  timeLimit?: number;          // 限时选择（秒），0=不限时
+}
+
+interface Condition {
+  variable: string;
+  op: '>' | '<' | '>=' | '<=' | '==' | '!=' | 'hasFlag';
+  value: number | string | boolean;
+}
+
+interface Effect {
+  type: 'set' | 'add' | 'toggleFlag' | 'triggerEvent';
+  target: string;
+  value?: number | string | boolean;
+}
+```
+
+#### 3. 状态系统 + 条件求值
+
+```typescript
+class StateManager {
+  variables: Map<string, number>;   // 人物好感度、勇气值等
+  flags: Set<string>;                // 剧情旗标
+  history: ChoiceRecord[];           // 选择历史（用于回溯）
+
+  // 条件求值
+  evaluate(conditions: Condition[]): boolean {
+    return conditions.every(c => {
+      const val = this.variables.get(c.variable) ?? 0;
+      switch (c.op) {
+        case '>=': return val >= (c.value as number);
+        case '==': return val === c.value;
+        case 'hasFlag': return this.flags.has(c.variable);
+        // ...
+      }
+    });
+  }
+
+  // 执行效果
+  apply(effects: Effect[]) {
+    for (const e of effects) {
+      if (e.type === 'add') {
+        this.variables.set(e.target,
+          (this.variables.get(e.target) ?? 0) + (e.value as number));
+      }
+      if (e.type === 'toggleFlag') this.flags.add(e.target);
+      // ...
+    }
+  }
+}
+```
+
+#### 4. QTE 系统
+
+```typescript
+interface QTEDefinition {
+  triggerTime: number;          // 视频播放到第几秒触发
+  prompt: string;               // 屏幕提示文字
+  keys: string[];               // 玩家需按的键 ['Space'] 或序列 ['W','A','S','D']
+  timeLimit: number;            // 限时（秒）
+  successScene: string;
+  failScene: string;
+  effects?: {                   // 成功/失败时各自的效果
+    success: Effect[];
+    fail: Effect[];
+  };
+}
+```
+
+#### 5. Save/Load 系统
+
+```typescript
+interface SaveData {
+  slot: number;
+  timestamp: number;
+  currentScene: string;
+  variables: Record<string, number>;
+  flags: string[];
+  history: ChoiceRecord[];
+  thumbnail?: string;           // 存档缩略图（当前帧截图）
+}
+
+class SaveSystem {
+  // 使用 IndexedDB（可存视频截图等大对象）
+  async save(slot: number): Promise<void> { /* ... */ }
+  async load(slot: number): Promise<SaveData> { /* ... */ }
+}
+```
+
+#### 6. 编辑器设计
+
+- **基于 React Flow** 的节点图编辑器，拖拽连线构建剧情分支
+- 每个节点可配置：视频文件、字幕、选择项、条件、效果、QTE
+- 导出为标准 JSON，直接给引擎消费
+- 内置视频预览 + 模拟运行功能
+- 技术栈：React + React Flow + Zustand（状态管理）+ Monaco Editor（高级编辑）
+
+### 四、推荐实现路线
+
+| 阶段 | 内容 | 预计工作量 |
+|------|------|-----------|
+| **P0 MVP** | 单视频播放 + 选择按钮 + JSON 场景定义 | 3-5 天 |
+| **P1 核心** | 双缓冲无缝切换 + 条件分支 + 状态系统 + IndexedDB 存档 | 1-2 周 |
+| **P2 进阶** | QTE 系统 + 字幕 + 音频管理 + 多存档槽位 | 1 周 |
+| **P3 编辑器** | React Flow 可视化剧情编辑器 | 2-3 周 |
+
+### 五、技术选型建议
+
+| 层 | 推荐 | 备选 |
+|----|------|------|
+| 语言 | TypeScript | JavaScript |
+| 构建 | Vite | webpack |
+| 视频 | 原生 `<video>` + Media Source API | hls.js / Shaka Player |
+| 存储 | IndexedDB (Dexie.js) | localStorage |
+| UI 框架 | React | Vue / Svelte / 原生 DOM |
+| 编辑器 | React Flow | 自绘 Canvas / Rete.js |

+## User
+
+能不能选择Vue技术栈
+
+---
+
+## Assistant (Plan · DeepSeek V4 Pro · 20.3s)
+
+_Thinking:_
+
+The user is asking if Vue can be used instead of React. This is a straightforward question - Vue is absolutely suitable for this project. Let me update the plan with Vue-specific technology choices.
+
+Key changes needed:
+- UI framework: Vue 3 (Composition API)
+- Build: Vite (Vue's first-class support)
+- Editor: Vue Flow (Vue port of React Flow) or use diagram libraries compatible with Vue
+- State management: Pinia (Vue's official state management)
+- Other parts like engine core, video management, etc. remain framework-agnostic
+
+Let me outline the Vue-specific plan.
+
+可以用 Vue，技术栈调整如下：
+
+## Vue 技术栈方案
+
+### 与 React 方案的对应替换
+
+| 层 | React 方案 | Vue 方案 |
+|----|-----------|---------|
+| UI 框架 | React | **Vue 3** (Composition API + `<script setup>`) |
+| 构建 | CRA / Vite | **Vite** (Vue 原生支持) |
+| 状态管理 | Zustand | **Pinia** |
+| 可视化编辑器 | React Flow | **Vue Flow** (基于 React Flow 的 Vue3 移植) |
+| 语言 | TypeScript | TypeScript（Vue3 对 TS 支持成熟） |
+
+### 核心引擎层不受影响
+
+`engine/core/` 和 `engine/systems/` 下的 VideoManager、SceneManager、StateManager、SaveSystem 等核心逻辑**仍然是纯 TypeScript 类**，不依赖任何 UI 框架。Vue 只负责 UI 层（播放器容器、选择面板、QTE 叠加层、编辑器界面）。
+

+  "dependencies": {
+    "vue": "^3.4",
+    "pinia": "^2.1",
+    "@vue-flow/core": "^1.x",

+
+  onMounted(() => {
+    engine.value = new Engine(/* config */)
+    engine.value.on('sceneChange', (scene) => {
+      currentScene.value = scene
+      choices.value = scene.choices ?? []

+    engine.value.start()
+    isPlaying.value = true
+  })
+
+  onUnmounted(() => engine.value?.destroy())
+
+  return { currentScene, choices, isPlaying, engine }
+}
+```
+
+### 是否要开始执行？
+
+以上是完整的技术规划。如果确认方案，我可以从 **P0 MVP**（单视频播放 + 选择 + JSON 场景定义）开始实现。需要我动手吗？

+
+P0 MVP:
+- [ ] 项目脚手架：Vite + Vue3 + TypeScript + Pinia
+- [ ] `engine/core/Engine.ts` — 主循环骨架
+- [ ] `engine/core/SceneManager.ts` — 加载 JSON，按 ID 查找场景节点
+- [ ] `engine/core/VideoManager.ts` — 单 video 元素播放，监听 ended 事件
+- [ ] `engine/core/StateManager.ts` — 变量存取、条件求值、效果执行
+- [ ] `engine/types.ts` — 类型定义
+- [ ] `src/components/GamePlayer.vue` — 挂载 video，控制播放

+- [ ] `public/scenes/demo.json` — 编写一段简单剧情（3-4 个场景节点）
+- [ ] 验证：从 demo.json 加载场景，能走通 开始→选择→分支播放→结束 流程
+
+Let me start implementing this step by step.
+
+1. First, create the Vite + Vue3 + TS project scaffold
+2. Then create the engine core files
+3. Create the Vue components
+4. Create demo scene data
+5. Wire everything together
+
+Let me start by scaffolding the project.

+
+Actually, `npm create vite@latest .` won't work because `.` is not empty. Let me create it in a temp location and move files, or just use the `--` flag to override. Actually, Vite will ask to overwrite. Let me try.
+
+Wait, the directory has `ROADMAP.md` and `old/`. Let me just scaffold manually - create package.json, vite.config.ts, tsconfig.json, index.html, and the src structure by hand. This is actually faster and more controlled.

+Actually, let me just use npm create vite in a temp dir and move, or do it in place. Let me try in place since the `.` flag might work with yes flag.

+Now create the demo.json scene data. I need to create a simple branching narrative. Since we don't have actual videos, I'll use placeholder video URLs that point to sample videos. Actually, for the demo we need real playable videos. Let me use some public domain video samples. 
+
+Actually, for the demo to actually work and test the flow, I need video files. Let me create a simple demo scene JSON with placeholder URLs, and also create a small script to generate test videos, OR use some publicly available test videos.
+
+Let me think about this differently - for testing, I can use canvas-generated test videos or I can provide instructions on where to get sample videos. But for the demo to actually run end-to-end, we need video files.
+
+Let me create the demo JSON first with placeholder paths, and also generate some simple test videos using ffmpeg.
+
+Actually, let me just create tiny test videos using ffmpeg with solid colors and text. That way the flow can be demonstrated.

+ffmpeg is not available. Let me generate the videos using HTML5 Canvas + JavaScript in a simple build script, or just create placeholder videos. Actually, let me create a helper HTML page that generates them, or just use the browser's canvas API.
+
+Wait, the simplest approach: I'll create a script that generates simple MP4 files using the canvas + MediaRecorder API. Or even simpler - create static image frames and encode them.
+
+Actually, the very simplest: I'll create a utility page that generates the test videos in the browser, and the user can run it.
+
+But actually, for the demo to "just work" without videos, I should handle the case where video files don't exist gracefully. But that defeats the purpose of testing the flow.
+
+Let me think of another approach. I can generate the test videos programmatically. Let me check if we can install ffmpeg.
+
+Actually, let me just create the videos using node. I'll create a small script that generates MP4 files using pure JavaScript. But that's complex.
+
+The simplest approach: Let me install ffmpeg.

+All P0 tasks are done. Let me provide a summary to the user. The project is:
+- Running at http://localhost:5173/
+- TypeScript checks pass
+- Vite build succeeds
+- 7 demo scenes with generated test videos
+- Engine core (Engine, SceneManager, VideoManager, StateManager) working
+- Vue components (GamePlayer, ChoicePanel) working
+- Pinia store + composable bridge working
+
+P0 MVP 完成。项目结构：

+
+**验证结果**: TypeScript 零错误，Vite build 成功，dev server 运行在 `http://localhost:5173/`。
+
+实测流程：加载 demo.json → 播放 `intro` 视频 → 视频播完弹出 3 个选项 → 点击任一选择 → 切换到目标场景视频 → 直到结局场景显示"游戏结束"。
+
+需要继续 P1 还是调整当前实现？
