# Create Game Story Task
## Purpose
To identify the next logical game story based on project progress and epic definitions, and then to prepare a comprehensive, self-contained, and actionable story file using the `Game Story Template`. This task ensures the story is enriched with all necessary technical context, WeChat Mini Game-specific requirements (object architecture, JavaScript language selection, 60+ FPS performance targets), TDD test requirements, and acceptance criteria, making it ready for efficient implementation by a Game Developer Agent with minimal need for additional research or finding its own context.
## SEQUENTIAL Task Execution (Do not proceed until current Task is complete)
### 0. Load Core Configuration and Check Workflow
- Load `.bmad-wechat-mini-game-dev/config.yaml` from the project root
- If the file does not exist, HALT and inform the user: "core-config.yaml not found. This file is required for story creation. You can either: 1) Copy core-config.yaml from GITHUB bmad-core/ and configure it for your game project OR 2) Run the BMad installer against your project to upgrade and add the file automatically. Please add and configure before proceeding."
- Extract key configurations: `devStoryLocation`, `prd.*`, `architecture.*`, `workflow.*`
### 1. Identify Next Story for Preparation
#### 1.1 Locate Epic Files and Review Existing Stories
- Based on `prdSharded` from config, locate epic files (sharded location/pattern or monolithic PRD sections)
- If `devStoryLocation` has story files, load the highest `{epicNum}.{storyNum}.story.md` file
- **If highest story exists:**
- Verify status is 'Done'. If not, alert user: "ALERT: Found incomplete story! File: {lastEpicNum}.{lastStoryNum}.story.md Status: [current status] Check if TDD tests are passing. You should fix this story first, but would you like to accept risk & override to create the next story in draft?"
- If proceeding, select next sequential story in the current epic
- If epic is complete, prompt user: "Epic {epicNum} Complete: All stories in Epic {epicNum} have been completed. Would you like to: 1) Begin Epic {epicNum + 1} with story 1 2) Select a specific story to work on 3) Cancel story creation"
- **CRITICAL**: NEVER automatically skip to another epic. User MUST explicitly instruct which story to create.
- **If no story files exist:** The next story is ALWAYS 1.1 (first story of first epic)
- Announce the identified story to the user: "Identified next story for preparation: {epicNum}.{storyNum} - {Story Title}"
### 2. Gather Story Requirements and Previous Story Context
- Extract story requirements from the identified epic file or PRD section
- If previous story exists, review Dev Agent Record sections for:
- Completion Notes and Debug Log References
- Implementation deviations and technical decisions
- WeChat Mini Game-specific challenges (object structure, event connections, 60+ FPS violations)
- Language decisions (JavaScript choices and rationale)
- Resource loading and object pooling implementations
- TDD test coverage and any failing tests
- Extract relevant insights that inform the current story's preparation
### 3. Gather Architecture Context
#### 3.1 Determine Architecture Reading Strategy
- **If `architectureVersion: >= v3` and `architectureSharded: true`**: Read `{architectureShardedLocation}/index.md` then follow structured reading order below
- **Else**: Use monolithic `architectureFile` for similar sections
#### 3.2 Read Architecture Documents Based on Story Type
**For ALL Game Stories:** tech-stack.md, wechat-mini-game-project-structure.md, coding-standards.md, test-strategy and standards.md
**For Gameplay/Mechanics Stories, additionally:** gameplay-systems-architecture.md, object-architecture-details.md, physics-configuration.md, input-system-architecture.md, state-machine-architecture.md, resource-architecture.md
**For UI/UX Stories, additionally:** object-architecture-details.md, ui-architecture.md, ui-component-system.md, ui-state-management.md, scene-management-architecture.md
**For Backend/Services Stories, additionally:** resource-architecture.md, data-persistence-architecture.md, save-system-implementation.md, analytics-integration.md, multiplayer-architecture.md
**For Graphics/Rendering Stories, additionally:** rendering-settings.md, shader-guidelines.md, sprite-management.md, particle-systems.md
**For Audio Stories, additionally:** audio-architecture.md, audio-mixing-configuration.md, sound-bank-management.md
#### 3.3 Extract Story-Specific Technical Details
Extract ONLY information directly relevant to implementing the current story. Do NOT invent new patterns, systems, or standards not in the source documents.
Extract:
- Specific WeChat Mini Game objects and their inheritance hierarchy
- Language selection rationale (JavaScript for each component)
- Object composition patterns and event connections
- Scene and resource organization requirements
- Input handling configurations
- Physics settings and collision layers
- UI element anchoring and theme specifications
- Resource naming conventions and folder structures
- Performance budgets (60+ FPS minimum, frame time <16.67ms, draw calls)
- Platform export settings (desktop, mobile)
- TDD requirements
ALWAYS cite source documents: `[Source: architecture/{filename}.md#{section}]`
### 4. WeChat Mini Game-Specific Technical Analysis
#### 4.1 Language Strategy Analysis
- Document JavaScript enforcement
- Identify interop boundaries between JavaScript and other languages
- Note any plugin requirements
- Specify object pooling needs for spawned entities
#### 4.2 Scene and Object Planning
- Identify which scenes will be modified or created
- List scene inheritance and composition patterns
- Document object tree structure with parent-child relationships
- Specify scene instancing and pooling requirements
- Plan event connections between objects
- Define global manager needs
#### 4.3 Object Architecture
- Define custom object classes needed
- Specify Resource classes for data management
- Document event emission and connection patterns
- Note UI components and theme requirements
- Plan export variables for inspector configuration
#### 4.4 Resource Requirements
- List texture requirements with import settings
- Define Animation needs
- Specify Audio resources and bus routing
- Document shader and material requirements
- Note font resources and theme variations
- Plan resource preloading vs lazy loading strategy
### 5. Populate Story Template with Full Context
- Create new story file: `{devStoryLocation}/{epicNum}.{storyNum}.story.md` using Game Story Template
- Fill in basic story information: Title, Status (Draft), Story statement, Acceptance Criteria from Epic/PRD
- **`Dev Notes` section (CRITICAL):**
- CRITICAL: This section MUST contain ONLY information extracted from architecture documents and PRD. NEVER invent or assume technical details.

- **Performance Targets**: 60+ FPS requirement, frame time budget, profiler metrics
- **Platform Considerations**: Export template differences, platform-specific code
- **TDD Requirements**: Test-first development
- Every technical detail MUST include its source reference: `[Source: architecture/{filename}.md#{section}]`
- If information for a category is not found in the architecture docs, explicitly state: "No specific guidance found in architecture docs"
- **`Tasks / Subtasks` section:**
- Generate detailed, sequential list of technical tasks based ONLY on: Epic/PRD Requirements, Story AC, Reviewed Architecture Information

- Each task must reference relevant architecture documentation
- Include testing as explicit subtasks
- Link tasks to ACs where applicable (e.g., `Task 1 (AC: 1, 3)`)
- Add notes on WeChat Mini Game project structure alignment or discrepancies found in Step 4
