From a7038d43d18246f6aef175aa89ba059b7c94f61f Mon Sep 17 00:00:00 2001 From: PinkyD Date: Wed, 23 Jul 2025 05:14:06 -0700 Subject: [PATCH] feat: Overhaul and Enhance 2D Unity Game Dev Expansion Pack (#350) * Updated game-sm agent to match the new core framework patterns * feat:Created more comprehensive game story matching new format system as well * feat:Added Game specific course correct task * feat:Updated dod-checklist to match new DoD format * feat:Added new Architect agent for appropriate architecture doc creation and design * feat:Overhaul of game-architecture-tmpl template * feat:Updated rest of templates besides level which doesnt really need it * feat: Finished extended architecture documentation needed for new game story tasks * feat: Updated game Developer to new format * feat: Updated last agent to new format and updated bmad-kb. bmad-kb I did my best with but im not sure of it's valid usage in the expansion pack, the AI generated more of the file then myself. I made sure to include it due to the new core-config file * feat: Finished updating designer agent to new format and cleaned up template linting errors * Built dist for web bundle * Increased expansion pack minor verison number * Updated architecht and design for sharding built-in * chore: bump bmad-2d-unity-game-dev version (minor) * updated config.yaml for game-specific pieces to supplement core-config.yaml * Updated game-core-config and epic processing for game story and game design. Initial implementation was far too generic * chore: bump bmad-2d-unity-game-dev version (patch) * feat: Fixed issue with multi-configs being needed. chore: bump bmad-2d-unity-game-dev version (patch) * Chore: Built web-bundle * feat: Added the ability to specify the unity editor install location.\nchore: bump bmad-2d-unity-game-dev version (patch) * feat: core-config must be in two places to support inherited tasks at this time so added instructions to copy and create one in expansion pack folder as well. chore: bump bmad-2d-unity-game-dev version (patch) --- dist/agents/analyst.txt | 12 +- dist/agents/architect.txt | 11 +- dist/agents/bmad-master.txt | 3 +- dist/agents/pm.txt | 9 +- dist/agents/po.txt | 320 +- dist/agents/qa.txt | 1 -

Also, ask if there's a specific player demographic or experience level they have in mind (casual players, hardcore gamers, children, etc.). Once clarified, perform the expansion or contraction from your current game design role's perspective, tailored to the specified player audience if provided.]] + +1. Explain Game Design Reasoning (Step-by-Step) + [[LLM: Explain the step-by-step game design thinking process that you used to arrive at the current proposal for this game content. Focus on player psychology, engagement mechanics, technical feasibility, and how design decisions support the overall player experience goals.]] + +2. Critique and Refine from Player Perspective + [[LLM: From your current game design role's perspective, review your last output or the current section for potential player confusion, engagement issues, balance problems, or areas for improvement. Consider how players will actually interact with and experience these systems, then suggest a refined version that better serves player enjoyment and understanding.]] + +3. Analyze Game Flow and Mechanic Dependencies + [[LLM: From your game design role's standpoint, examine the content's structure for logical gameplay progression, mechanic interdependencies, and player learning curve. Confirm if game elements are introduced in an effective order that teaches players naturally and maintains engagement throughout the experience.]] + +4. Assess Alignment with Player Experience Goals + [[LLM: Evaluate how well the current game design content contributes to the stated player experience goals and core game pillars. Consider whether the mechanics actually create the intended emotions and engagement patterns. Identify any misalignments between design intentions and likely player reactions.]] + +5. Identify Potential Player Confusion and Design Risks + [[LLM: Based on your game design expertise, brainstorm potential sources of player confusion, overlooked edge cases in gameplay, balance issues, technical implementation risks, or unintended player behaviors that could emerge from the current design. Consider both new and experienced players' perspectives.]] + +6. Challenge from Critical Game Design Perspective + [[LLM: Adopt a critical game design perspective on the current content. If the user specifies another viewpoint (e.g., 'as a casual player', 'as a speedrunner', 'as a mobile player', 'as a technical implementer'), critique the content from that specified perspective. If no other role is specified, play devil's advocate from your game design expertise, arguing against the current design proposal and highlighting potential weaknesses, player experience issues, or implementation challenges. This can include questioning scope creep, unnecessary complexity, or features that don't serve the core player experience.]] + +7. Explore Alternative Game Design Approaches + [[LLM: From your game design role's perspective, first broadly brainstorm a range of diverse approaches to achieving the same player experience goals or solving the same design challenge. Consider different genres, mechanics, interaction models, or technical approaches. Then, from this wider exploration, select and present 2-3 distinct alternative design approaches, detailing the pros, cons, player experience implications, and technical feasibility you foresee for each.]] + +8. Hindsight Postmortem: The 'If Only...' Game Design Reflection + [[LLM: In your current game design persona, imagine this is a postmortem for a shipped game based on the current design content. What's the one 'if only we had designed/considered/tested X...' that your role would highlight from a game design perspective? Include the imagined player reactions, review scores, or development consequences. This should be both insightful and somewhat humorous, focusing on common game design pitfalls.]] + +9.

These guidelines ensure consistency, performance, and maintainability across all game development stories. + +## C# Standards + +### Naming Conventions + +**Classes, Structs, Enums, and Interfaces:** + +- PascalCase for types: `PlayerController`, `GameData`, `IInteractable` +- Prefix interfaces with 'I': `IDamageable`, `IControllable` +- Descriptive names that indicate purpose: `GameStateManager` not `GSM` + +**Methods and Properties:** + +- PascalCase for methods and properties: `CalculateScore()`, `CurrentHealth` +- Descriptive verb phrases for methods: `ActivateShield()` not `shield()` + +**Fields and Variables:** + +- `private` or `protected` fields: camelCase with an underscore prefix: `_playerHealth`, `_movementSpeed` +- `public` fields (use sparingly, prefer properties): PascalCase: `PlayerName` +- `static` fields: PascalCase: `Instance`, `GameVersion` +- `const` fields: PascalCase: `MaxHitPoints` +- `local` variables: camelCase: `damageAmount`, `isJumping` +- Boolean variables with is/has/can prefix: `_isAlive`, `_hasKey`, `_canJump` + +**Files and Directories:** + +- PascalCase for C# script files, matching the primary class name: `PlayerController.cs` +- PascalCase for Scene files: `MainMenu.unity`, `Level01.unity` + +### Style and Formatting + +- **Braces**: Use Allman style (braces on a new line). +- **Spacing**: Use 4 spaces for indentation (no tabs). +- **`using` directives**: Place all `using` directives at the top of the file, outside the namespace. +- **`this` keyword**: Only use `this` when necessary to distinguish between a field and a local variable/parameter. + +## Unity Architecture Patterns + +### Scene Lifecycle Management + +**Loading and Transitioning Between Scenes:** + +```csharp +// SceneLoader.cs - A singleton for managing scene transitions. +using UnityEngine; +using UnityEngine.SceneManagement; +using System.Collections; + +public class SceneLoader : MonoBehaviour +{ + public static SceneLoader Instance { get; private set; } + + private void Awake() + { + if (Instance != null && Instance != this) + { + Destroy(gameObject); + return; + } + Instance = this; + DontDestroyOnLoad(gameObject); + } + + public void LoadGameScene() + { + // Example of loading the main game scene, perhaps with a loading screen first. + StartCoroutine(LoadSceneAsync("Level01")); + } + + private IEnumerator LoadSceneAsync(string sceneName) + { + // Load a loading screen first (optional) + SceneManager.LoadScene("LoadingScreen"); + + // Wait a frame for the loading screen to appear + yield return null; + + // Begin loading the target scene in the background + AsyncOperation asyncLoad = SceneManager.LoadSceneAsync(sceneName); + + // Don't activate the scene until it's fully loaded + asyncLoad.allowSceneActivation = false; + + // Wait until the asynchronous scene fully loads + while (!asyncLoad.isDone) + { + // Here you could update a progress bar with asyncLoad.progress + if (asyncLoad.progress >= 0.9f) + { + // Scene is loaded, allow activation + asyncLoad.allowSceneActivation = true; + } + yield return null; + } + } +} +``` + +### MonoBehaviour Lifecycle + +**Understanding Core MonoBehaviour Events:** + +```csharp +// Example of a standard MonoBehaviour lifecycle +using UnityEngine; + +public class PlayerController : MonoBehaviour +{ + // AWAKE: Called when the script instance is being loaded. + // Use for initialization before the game starts. Good for caching component references. + private void Awake() + { + Debug.Log("PlayerController Awake!"); + } + + // ONENABLE: Called when the object becomes enabled and active. + // Good for subscribing to events. + private void OnEnable() + { + // Example: UIManager.OnGamePaused += HandleGamePaused; + } + + // START: Called on the frame when a script is enabled just before any of the Update methods are called the first time. + // Good for logic that depends on other objects being initialized. + private void Start() + { + Debug.Log("PlayerController Start!"); + } + + // FIXEDUPDATE: Called every fixed framerate frame. + // Use for physics calculations (e.g., applying forces to a Rigidbody). + private void FixedUpdate() + { + // Handle Rigidbody movement here. + } + + // UPDATE: Called every frame. + // Use for most game logic, like handling input and non-physics movement. + private void Update() + { + // Handle input and non-physics movement here. + } + + // LATEUPDATE: Called every frame, after all Update functions have been called. + // Good for camera logic that needs to track a target that moves in Update. + private void LateUpdate() + { + // Camera follow logic here. + } + + // ONDISABLE: Called when the behaviour becomes disabled or inactive. + // Good for unsubscribing from events to prevent memory leaks. + private void OnDisable() + { + // Example: UIManager.OnGamePaused -= HandleGamePaused; + } + + // ONDESTROY: Called when the MonoBehaviour will be destroyed. + // Good for any final cleanup. + private void OnDestroy() + { + Debug.Log("PlayerController Destroyed!"); + } +} +``` + +### Game Object Patterns + +**Component-Based Architecture:** + +```csharp +// Player.cs - The main GameObject class, acts as a container for components. +using UnityEngine; + +[RequireComponent(typeof(PlayerMovement), typeof(PlayerHealth))] +public class Player : MonoBehaviour +{ + public PlayerMovement Movement { get; private set; } + public PlayerHealth Health { get; private set;

+ } + } + + private void Die() + { + // Death logic + Debug.Log("Player has died."); + gameObject.SetActive(false); + } +} +``` + +### Data-Driven Design with ScriptableObjects + +**Define Data Containers:** + +```csharp +// EnemyData.cs - A ScriptableObject to hold data for an enemy type. +using UnityEngine; + +[CreateAssetMenu(fileName = "NewEnemyData", menuName = "Game/Enemy Data")] +public class EnemyData : ScriptableObject +{ + public string enemyName; + public int maxHealth; + public float moveSpeed;

+ + private void Start() + { + _currentHealth = _enemyData.maxHealth; + GetComponent().sprite = _enemyData.sprite; + } + + // ... other enemy logic +} +``` + +### System Management + +**Singleton Managers:** + +```csharp +// GameManager.cs - A singleton to manage the overall game state. +using UnityEngine; + +public class GameManager : MonoBehaviour +{ + public static GameManager Instance { get; private set; } + + public int Score { get; private set; } + + private void Awake() + { + if (Instance != null && Instance != this) + { + Destroy(gameObject); + return; + } + Instance = this; + DontDestroyOnLoad(gameObject); // Persist across scenes + } + + public void AddScore(int amount) + { + Score += amount; + } +} +``` + +## Performance Optimization + +### Object Pooling + +**Required for High-Frequency Objects (e.g., bullets, effects):** + +```csharp +// ObjectPool.cs - A generic object pooling system. +using UnityEngine; +using System.Collections.Generic; + +public class ObjectPool : MonoBehaviour +{ + [SerializeField] private GameObject _prefabToPool; + [SerializeField] private int _initialPoolSize = 20; + + private Queue _pool = new Queue(); + + private void Start() + { + for (int i = 0; i < _initialPoolSize; i++) + { + GameObject obj = Instantiate(_prefabToPool); + obj.SetActive(false); + _pool.Enqueue(obj); + } + } + + public GameObject GetObjectFromPool() + { + if (_pool.Count > 0) + { + GameObject obj = _pool.Dequeue(); + obj.SetActive(true); + return obj; + } + // Optionally, expand the pool if it's empty. + return Instantiate(_prefabToPool); + } + + public void ReturnObjectToPool(GameObject obj) + { + obj.SetActive(false); + _pool.Enqueue(obj); + } +} +``` + +### Frame Rate Optimization + +**Update Loop Optimization:** + +- Avoid expensive calls like `GetComponent`, `FindObjectOfType`, or `Instantiate` inside `Update()` or `FixedUpdate()`. Cache references in `Awake()` or `Start()`. +- Use Coroutines or simple timers for logic that doesn't need to run every single frame. + +**Physics Optimization:** + +- Adjust the "Physics 2D Settings" in Project Settings, especially the "Layer Collision Matrix", to prevent unnecessary collision checks. +- Use `Rigidbody2D.Sleep()` for objects that are not moving to save CPU cycles. + +## Input Handling + +### Cross-Platform Input (New Input System) + +**Input Action Asset:** Create an Input Action Asset (`.inputactions`) to define controls. + +**PlayerInput Component:** + +- Add the `PlayerInput` component to the player GameObject. +- Set its "Actions" to the created Input Action Asset. +- Set "Behavior" to "Invoke Unity Events" to easily hook up methods in the Inspector, or "Send Messages" to use methods like `OnMove`, `OnFire`. + +```csharp +// PlayerInputHandler.cs - Example of handling input via messages. +using UnityEngine; +using UnityEngine.InputSystem; + +public class PlayerInputHandler : MonoBehaviour +{ + private Vector2 _moveInput; + + // This method is called by the PlayerInput component via "Send Messages". + // The action must be named "Move" in the Input Action Asset. + public void OnMove(InputValue value) + { + _moveInput = value.Get(); + } + + private void Update() + { + // Use _moveInput to control the player + transform.Translate(new Vector3(_moveInput.x, _moveInput.y, 0) * Time.deltaTime * 5f); + } +} +``` + +## Error Handling + +### Graceful Degradation + +**Asset Loading Error Handling:** + +- When using Addressables or `Resources.Load`, always check if the loaded asset is null before using it. + +```csharp +// Load a sprite and use a fallback if it fails +Sprite playerSprite = Resources.Load("Sprites/Player"); +if (playerSprite == null) +{ + Debug.LogError("Player sprite not found! Using default."); + playerSprite = Resources.Load("Sprites/Default"); +} +``` + +### Runtime Error Recovery + +**Assertions and Logging:** + +- Use `Debug.Assert(condition, "Message")` to check for critical conditions that must be true. +- Use `Debug.LogError("Message")` for fatal errors and `Debug.LogWarning("Message")` for non-critical issues. + +```csharp +// Example of using an assertion to ensure a component exists. +private Rigidbody2D _rb; + +void Awake() +{ + _rb = GetComponent(); + Debug.Assert(_rb != null, "Rigidbody2D component not found on player!"); +} +``` + +## Testing Standards + +### Unit Testing (Edit Mode) + +**Game Logic Testing:** + +```csharp +// HealthSystemTests.cs - Example test for a simple health system. +using NUnit.Framework; +using UnityEngine; + +public class HealthSystemTests +{ + [Test] + public void TakeDamage_ReducesHealth() + { + // Arrange + var gameObject = new GameObject(); + var healthSystem = gameObject.AddComponent(); + // Note: This is a simplified example. You might need to mock dependencies. + + // Act + healthSystem.TakeDamage(20); + + // Assert + // This requires making health accessible for testing, e.g., via a public property or method. + // Assert.AreEqual(80, healthSystem.CurrentHealth); + } +} +``` + +### Integration Testing (Play Mode) + +**Scene Testing:** + +- Play Mode tests run in a live scene, allowing you to test interactions between multiple components and systems. +- Use `yield return null;` to wait for the next frame. + +```csharp +// PlayerJumpTest.cs +using System.Collections; +using NUnit.Framework; +using UnityEngine; +using UnityEngine.TestTools; + +public class PlayerJumpTest +{ + [UnityTest] + public IEnumerator PlayerJumps_WhenSpaceIsPressed() + { + // Arrange + var player = new GameObject().AddComponent(); + var initialY = player.transform.position.y; + + // Act + // Simulate pressing the jump button (requires setting up the input system for tests) + // For simplicity, we'll call a public method here. + // player.Jump(); + + // Wait for a few physics frames + yield return new WaitForSeconds(0.5f); + + // Assert + Assert.Greater(player.transform.position.y, initialY); + } +} +``` + +## File Organization + +### Project Structure + +``` +Assets/ +├── Scenes/ +│ ├── MainMenu.unity +│ └── Level01.unity +├── Scripts/ +│ ├── Core/ +│ │ ├── GameManager.cs +│ │ └── AudioManager.cs +│ ├── Player/ +│ │ ├── PlayerController.cs +│ │ └── PlayerHealth.cs +│ ├── Editor/ +│ │ └── CustomInspectors.cs +│ └── Data/ +│ └── EnemyData.cs +├── Prefabs/ +│ ├── Player.prefab +│ └── Enemies/ +│ └── Slime.prefab +├── Art/ +│ ├── Sprites/ +│ └── Animations/ +├── Audio/ +│ ├── Music/ +│ └── SFX/ +├── Data/ +│ └── ScriptableObjects/ +│ └── EnemyData/ +└── Tests/ + ├── EditMode/ + │ └── HealthSystemTests.cs + └── PlayMode/ + └── PlayerJumpTest.cs +``` + +## Development Workflow + +### Story Implementation Process + +1. **Read Story Requirements:** + + - Understand acceptance criteria + - Identify technical requirements + - Review performance constraints + +2. **Plan Implementation:** + + - Identify files to create/modify + - Consider Unity's component-based architecture + - Plan testing approach + +3. **Implement Feature:** + + - Write clean C# code following all guidelines + - Use established patterns + - Maintain stable FPS performance + +4. **Test Implementation:** + + - Write edit mode tests for game logic + - Write play mode tests for integration testing + - Test cross-platform functionality + - Validate performance targets + +5. **Update Documentation:** + - Mark story checkboxes complete + - Document any deviations + - Update architecture if needed + +### Code Review Checklist + +- [ ] C# code compiles without errors or warnings. +- [ ] All automated tests pass. +- [ ] Code follows naming conventions and architectural patterns. +- [ ] No expensive operations in `Update()` loops. +- [ ] Public fields/methods are documented with comments. +- [ ] New assets are organized into the correct folders. + +## Performance Targets + +### Frame Rate Requirements + +- **PC/Console**: Maintain a stable 60+ FPS. +- **Mobile**: Maintain 60 FPS on mid-range devices, minimum 30 FPS on low-end. +- **Optimization**: Use the Unity Profiler to identify and fix performance drops. + +### Memory Management + +- **Total Memory**: Keep builds under platform-specific limits (e.g., 200MB for a simple mobile game). +- **Garbage Collection**: Minimize GC spikes by avoiding string concatenation, `new` keyword usage in loops, and by pooling objects. + +### Loading Performance + +- **Initial Load**: Under 5 seconds for game start. +- **Scene Transitions**: Under 2 seconds between scenes.

Especially Gemini for Game Design!) + +**Ideal for cost efficiency with Gemini's massive context for game brainstorming:** + +**For All Game Projects**: + +1. **Game Concept Brainstorming**: `/bmad2du/game-designer` - Use `*game-design-brainstorming` task +2. **Game Brief**: Create foundation game document using `game-brief-tmpl` +3. **Game Design Document Creation**: `/bmad2du/game-designer` - Use `game-design-doc-tmpl` for comprehensive game requirements +4. **Game Architecture Design**: `/bmad2du/game-architect` - Use `game-architecture-tmpl` for Unity technical foundation +5. **Level Design Framework**: `/bmad2du/game-designer` - Use `level-design-doc-tmpl` for level structure planning +6. **Document Preparation**: Copy final documents to Unity project as `docs/game-design-doc.md`, `docs/game-brief.md`, `docs/level-design.md` and `docs/game-architecture.md` + +#### Example Game Planning Prompts + +**For Game Design Document Creation**: + +```text +"I want to build a [genre] 2D game that [core gameplay]. +Help me brainstorm mechanics and create a comprehensive Game Design Document." +``` + +**For Game Architecture Design**: + +```text +"Based on this Game Design Document, design a scalable Unity architecture +that can handle [specific game requirements] with stable performance." +``` + +### Critical Transition: Web UI to Unity IDE + +**Once game planning is complete, you MUST switch to IDE for Unity development:** + +- **Why**: Unity development workflow requires C# operations, asset management, and real-time Unity testing +- **Cost Benefit**: Web UI is more cost-effective for large game design creation; IDE is optimized for Unity development +- **Required Files**: Ensure `docs/game-design-doc.md` and `docs/game-architecture.md` exist in your Unity project + +### Unity IDE Development Workflow + +**Prerequisites**: Game planning documents must exist in `docs/` folder of Unity project + +1. **Document Sharding** (CRITICAL STEP for Game Development): + + - Documents created by Game Designer/Architect (in Web or IDE) MUST be sharded for development + - Use core BMad agents or tools to shard: + a) **Manual**: Use core BMad `shard-doc` task if available + b) **Agent**: Ask core `@bmad-master` agent to shard documents + - Shards `docs/game-design-doc.md` → `docs/game-design/` folder + - Shards `docs/game-architecture.md` → `docs/game-architecture/` folder + - **WARNING**: Do NOT shard in Web UI - copying many small files to Unity is painful! + +2. **Verify Sharded Game Content**: + - At least one `feature-n.md` file in `docs/game-design/` with game stories in development order + - Unity system documents and coding standards for game dev agent reference + - Sharded docs for Game SM agent story creation + +Resulting Unity Project Folder Structure: + +- `docs/game-design/` -

Especially Gemini for Game Design!) + +**Ideal for cost efficiency with Gemini's massive context for game brainstorming:** + +**For All Game Projects**: + +1. **Game Concept Brainstorming**: `/bmad2du/game-designer` - Use `*game-design-brainstorming` task +2. **Game Brief**: Create foundation game document using `game-brief-tmpl` +3. **Game Design Document Creation**: `/bmad2du/game-designer` - Use `game-design-doc-tmpl` for comprehensive game requirements +4. **Game Architecture Design**: `/bmad2du/game-architect` - Use `game-architecture-tmpl` for Unity technical foundation +5. **Level Design Framework**: `/bmad2du/game-designer` - Use `level-design-doc-tmpl` for level structure planning +6. **Document Preparation**: Copy final documents to Unity project as `docs/game-design-doc.md`, `docs/game-brief.md`, `docs/level-design.md` and `docs/game-architecture.md` + +#### Example Game Planning Prompts + +**For Game Design Document Creation**: + +```text +"I want to build a [genre] 2D game that [core gameplay]. +Help me brainstorm mechanics and create a comprehensive Game Design Document." +``` + +**For Game Architecture Design**: + +```text +"Based on this Game Design Document, design a scalable Unity architecture +that can handle [specific game requirements] with stable performance." +``` + +### Critical Transition: Web UI to Unity IDE + +**Once game planning is complete, you MUST switch to IDE for Unity development:** + +- **Why**: Unity development workflow requires C# operations, asset management, and real-time Unity testing +- **Cost Benefit**: Web UI is more cost-effective for large game design creation; IDE is optimized for Unity development +- **Required Files**: Ensure `docs/game-design-doc.md` and `docs/game-architecture.md` exist in your Unity project + +### Unity IDE Development Workflow + +**Prerequisites**: Game planning documents must exist in `docs/` folder of Unity project + +1. **Document Sharding** (CRITICAL STEP for Game Development): + + - Documents created by Game Designer/Architect (in Web or IDE) MUST be sharded for development + - Use core BMad agents or tools to shard: + a) **Manual**: Use core BMad `shard-doc` task if available + b) **Agent**: Ask core `@bmad-master` agent to shard documents + - Shards `docs/game-design-doc.md` → `docs/game-design/` folder + - Shards `docs/game-architecture.md` → `docs/game-architecture/` folder + - **WARNING**: Do NOT shard in Web UI - copying many small files to Unity is painful! + +2. **Verify Sharded Game Content**: + - At least one `feature-n.md` file in `docs/game-design/` with game stories in development order + - Unity system documents and coding standards for game dev agent reference + - Sharded docs for Game SM agent story creation + +Resulting Unity Project Folder Structure: + +- `docs/game-design/` - Broken down game design sections +- `docs/game-architecture/` - Broken down Unity architecture sections +- `docs/game-stories/` - Generated game development stories + +3. **Game Development Cycle** (Sequential, one game story at a time): + + **CRITICAL CONTEXT MANAGEMENT for Unity Development**: + + - **Context windows matter!** Always use fresh, clean context windows + - **Model selection matters!** Use most powerful thinking model for Game SM story creation + - **ALWAYS start new chat between Game SM, Game Dev, and QA work** + + **Step 1 - Game Story Creation**: + + - **NEW CLEAN CHAT** → Select powerful model → `/bmad2du/game-sm` → `*draft` + - Game SM executes create-game-story task using `game-story-tmpl` + - Review generated story in `docs/game-stories/` + - Update status from "Draft" to "Approved" + + **Step 2 - Unity Game Story Implementation**: + + - **NEW CLEAN CHAT** → `/bmad2du/game-developer` + - Agent asks which game story to implement + - Include story file content to save game dev agent lookup time + - Game Dev follows tasks/subtasks, marking completion + - Game Dev maintains File List of all Unity/C# changes + - Game Dev marks story as "Review" when complete with all Unity tests passing + + **Step 3 - Game QA Review**: + + - **NEW CLEAN CHAT** → Use core `@qa` agent → execute review-story task + - QA performs senior Unity developer code review + - QA can refactor and improve Unity code directly + - QA appends results to story's QA Results section + - If approved: Status → "Done" + - If changes needed: Status stays "Review" with unchecked items for game dev + + **Step 4 - Repeat**: Continue Game SM → Game Dev → QA cycle until all game feature stories complete + +**Important**: Only 1 game story in progress at a time, worked sequentially until all game feature stories complete. + +### Game Story Status Tracking Workflow + +Game stories progress through defined statuses: + +- **Draft** → **Approved** → **InProgress** → **Done** + +Each status change requires user verification and approval before proceeding. + +### Game Development Workflow Types + +#### Greenfield Game Development + +- Game concept brainstorming and mechanics design +- Game design requirements and feature definition +- Unity system architecture and technical design +- Game development execution +- Game testing, performance optimization, and deployment + +#### Brownfield Game Enhancement (Existing Unity Projects) + +**Key Concept**: Brownfield game development requires comprehensive documentation of your existing Unity project for AI agents to understand game mechanics, Unity patterns, and technical constraints. + +**Brownfield Game Enhancement Workflow**: + +Since this expansion pack doesn't include specific brownfield templates, you'll adapt the existing templates: + +1. **Upload Unity project to Web UI** (GitHub URL, files, or zip) +2. **Create adapted Game Design Document**: `/bmad2du/game-designer` - Modify `game-design-doc-tmpl` to include: + + - Analysis of existing game systems + - Integration points for new features + - Compatibility requirements + - Risk assessment for changes + +3. **Game Architecture Planning**: + + - Use `/bmad2du/game-architect` with `game-architecture-tmpl` + - Focus on how new features integrate with existing Unity systems + - Plan for gradual rollout and testing + +4. **Story Creation for Enhancements**: + - Use `/bmad2du/game-sm` with `*create-game-story` + - Stories should explicitly reference existing code to modify + - Include integration testing requirements + +**When to Use Each Game Development Approach**: + +**Full Game Enhancement Workflow** (Recommended for): + +- Major game feature additions +- Game system modernization +- Complex Unity integrations +- Multiple related gameplay changes + +**Quick Story Creation** (Use when): + +- Single, focused game enhancement +- Isolated gameplay fixes +- Small feature additions +- Well-documented existing Unity game + +**Critical Success Factors for Game Development**: + +1. **Game Documentation First**: Always document existing code thoroughly before making changes +2. **Unity Context Matters**: Provide agents access to relevant Unity scripts and game systems +3. **Gameplay Integration Focus**: Emphasize compatibility and non-breaking changes to game mechanics +4. **Incremental Approach**: Plan for gradual rollout and extensive game testing + +## Document Creation Best Practices for Game Development + +### Required File Naming for Game Framework Integration + +- `docs/game-design-doc.md` -

These guidelines ensure consistency, performance, and maintainability across all game development stories. - -## C# Standards - -### Naming Conventions - -**Classes, Structs, Enums, and Interfaces:** -- PascalCase for types: `PlayerController`, `GameData`, `IInteractable` -- Prefix interfaces with 'I': `IDamageable`, `IControllable` -- Descriptive names that indicate purpose: `GameStateManager` not `GSM` - -**Methods and Properties:** -- PascalCase for methods and properties: `CalculateScore()`, `CurrentHealth` -- Descriptive verb phrases for methods: `ActivateShield()` not `shield()` - -**Fields and Variables:** -- `private` or `protected` fields: camelCase with an underscore prefix: `_playerHealth`, `_movementSpeed` -- `public` fields (use sparingly, prefer properties): PascalCase: `PlayerName` -- `static` fields: PascalCase: `Instance`, `GameVersion` -- `const` fields: PascalCase: `MaxHitPoints` -- `local` variables: camelCase: `damageAmount`, `isJumping` -- Boolean variables with is/has/can prefix: `_isAlive`, `_hasKey`, `_canJump` - -**Files and Directories:** -- PascalCase for C# script files, matching the primary class name: `PlayerController.cs` -- PascalCase for Scene files: `MainMenu.unity`, `Level01.unity` - -### Style and Formatting - -- **Braces**: Use Allman style (braces on a new line). -- **Spacing**: Use 4 spaces for indentation (no tabs). -- **`using` directives**: Place all `using` directives at the top of the file, outside the namespace. -- **`this` keyword**: Only use `this` when necessary to distinguish between a field and a local variable/parameter. - -## Unity Architecture Patterns - -### Scene Lifecycle Management -**Loading and Transitioning Between Scenes:** -```csharp -// SceneLoader.cs - A singleton for managing scene transitions. -using UnityEngine; -using UnityEngine.SceneManagement; -using System.Collections; - -public class SceneLoader : MonoBehaviour -{ - public static SceneLoader Instance { get; private set; } - - private void Awake() - { - if (Instance != null && Instance != this) - { - Destroy(gameObject); - return; - } - Instance = this; - DontDestroyOnLoad(gameObject); - } - - public void LoadGameScene() - { - // Example of loading the main game scene, perhaps with a loading screen first. - StartCoroutine(LoadSceneAsync("Level01")); - } - - private IEnumerator LoadSceneAsync(string sceneName) - { - // Load a loading screen first (optional) - SceneManager.LoadScene("LoadingScreen"); - - // Wait a frame for the loading screen to appear - yield return null; - - // Begin loading the target scene in the background - AsyncOperation asyncLoad = SceneManager.LoadSceneAsync(sceneName); - - // Don't activate the scene until it's fully loaded - asyncLoad.allowSceneActivation = false; - - // Wait until the asynchronous scene fully loads - while (!asyncLoad.isDone) - { - // Here you could update a progress bar with asyncLoad.progress - if (asyncLoad.progress >= 0.9f) - { - // Scene is loaded, allow activation - asyncLoad.allowSceneActivation = true; - } - yield return null; - } - } -} -``` - -### MonoBehaviour Lifecycle -**Understanding Core MonoBehaviour Events:** -```csharp -// Example of a standard MonoBehaviour lifecycle -using UnityEngine; - -public class PlayerController : MonoBehaviour -{ - // AWAKE: Called when the script instance is being loaded. - // Use for initialization before the game starts. Good for caching component references. - private void Awake() - { - Debug.Log("PlayerController Awake!"); - } - - // ONENABLE: Called when the object becomes enabled and active. - // Good for subscribing to events. - private void OnEnable() - { - // Example: UIManager.OnGamePaused += HandleGamePaused; - } - - // START: Called on the frame when a script is enabled just before any of the Update methods are called the first time. - // Good for logic that depends on other objects being initialized. - private void Start() - { - Debug.Log("PlayerController Start!"); - } - - // FIXEDUPDATE: Called every fixed framerate frame. - // Use for physics calculations (e.g., applying forces to a Rigidbody). - private void FixedUpdate() - { - // Handle Rigidbody movement here. - } - - // UPDATE: Called every frame. - // Use for most game logic, like handling input and non-physics movement. - private void Update() - { - // Handle input and non-physics movement here. - } - - // LATEUPDATE: Called every frame, after all Update functions have been called. - // Good for camera logic that needs to track a target that moves in Update. - private void LateUpdate() - { - // Camera follow logic here. - } - - // ONDISABLE: Called when the behaviour becomes disabled or inactive. - // Good for unsubscribing from events to prevent memory leaks. - private void OnDisable() - { - // Example: UIManager.OnGamePaused -= HandleGamePaused; - } - - // ONDESTROY: Called when the MonoBehaviour will be destroyed. - // Good for any final cleanup. - private void OnDestroy() - { - Debug.Log("PlayerController Destroyed!"); - } -} -``` - -### Game Object Patterns - -**Component-Based Architecture:** -```csharp -// Player.cs - The main GameObject class, acts as a container for components. -using UnityEngine; - -[RequireComponent(typeof(PlayerMovement), typeof(PlayerHealth))] -public class Player : MonoBehaviour -{ - public PlayerMovement Movement { get; private set; } - public PlayerHealth Health { get; private set; } - - private void Awake() - { - Movement = GetComponent(); - Health = GetComponent(); - } -} - -// PlayerHealth.cs - A component responsible only for health logic. -public class PlayerHealth : MonoBehaviour -{ - [SerializeField] private int _maxHealth = 100; - private int _currentHealth; - - private void Awake() - { - _currentHealth = _maxHealth; - } - - public void TakeDamage(int amount) - { - _currentHealth -= amount; - if (_currentHealth <= 0) - { - Die(); - } - } - - private void Die() - { - // Death logic - Debug.Log("Player has died."); - gameObject.SetActive(false); - } -} -``` - -### Data-Driven Design with ScriptableObjects - -**Define Data Containers:** -```csharp -// EnemyData.cs - A ScriptableObject to hold data for an enemy type. -using UnityEngine; - -[CreateAssetMenu(fileName = "NewEnemyData", menuName = "Game/Enemy Data")] -public class EnemyData : ScriptableObject -{ - public string enemyName; - public int maxHealth; - public float moveSpeed; - public int damage; - public Sprite sprite; -} - -// Enemy.cs - A MonoBehaviour that uses the EnemyData. -public class Enemy : MonoBehaviour -{ - [SerializeField] private EnemyData _enemyData; - private int _currentHealth; - - private void Start() - { - _currentHealth = _enemyData.maxHealth; - GetComponent().sprite = _enemyData.sprite; - } - - // ... other enemy logic -} -``` - -### System Management - -**Singleton Managers:** -```csharp -// GameManager.cs - A singleton to manage the overall game state. -using UnityEngine; - -public class GameManager : MonoBehaviour -{ - public static GameManager Instance { get; private set; } - - public int Score { get; private set; } - - private void Awake() - { - if (Instance != null && Instance != this) - { - Destroy(gameObject); - return; - } - Instance = this; - DontDestroyOnLoad(gameObject); // Persist across scenes - } - - public void AddScore(int amount) - { - Score += amount; - } -} -``` - -## Performance Optimization - -### Object Pooling - -**Required for High-Frequency Objects (e.g., bullets, effects):** -```csharp -// ObjectPool.cs - A generic object pooling system. -using UnityEngine; -using System.Collections.Generic; - -public class ObjectPool : MonoBehaviour -{ - [SerializeField] private GameObject _prefabToPool; - [SerializeField] private int _initialPoolSize = 20; - - private Queue _pool = new Queue(); - - private void Start() - { - for (int i = 0; i < _initialPoolSize; i++) - { - GameObject obj = Instantiate(_prefabToPool); - obj.SetActive(false); - _pool.Enqueue(obj); - } - } - - public GameObject GetObjectFromPool() - { - if (_pool.Count > 0) - { - GameObject obj = _pool.Dequeue(); - obj.SetActive(true); - return obj; - } - // Optionally, expand the pool if it's empty. - return Instantiate(_prefabToPool); - } - - public void ReturnObjectToPool(GameObject obj) - { - obj.SetActive(false); - _pool.Enqueue(obj); - } -} -``` - -### Frame Rate Optimization - -**Update Loop Optimization:** -- Avoid expensive calls like `GetComponent`, `FindObjectOfType`, or `Instantiate` inside `Update()` or `FixedUpdate()`. Cache references in `Awake()` or `Start()`. -- Use Coroutines or simple timers for logic that doesn't need to run every single frame. - -**Physics Optimization:** -- Adjust the "Physics 2D Settings" in Project Settings, especially the "Layer Collision Matrix", to prevent unnecessary collision checks. -- Use `Rigidbody2D.Sleep()` for objects that are not moving to save CPU cycles. - -## Input Handling - -### Cross-Platform Input (New Input System) - -**Input Action Asset:** Create an Input Action Asset (`.inputactions`) to define controls. - -**PlayerInput Component:** -- Add the `PlayerInput` component to the player GameObject. -- Set its "Actions" to the created Input Action Asset. -- Set "Behavior" to "Invoke Unity Events" to easily hook up methods in the Inspector, or "Send Messages" to use methods like `OnMove`, `OnFire`. - -```csharp -// PlayerInputHandler.cs - Example of handling input via messages. -using UnityEngine; -using UnityEngine.InputSystem; - -public class PlayerInputHandler : MonoBehaviour -{ - private Vector2 _moveInput; - - // This method is called by the PlayerInput component via "Send Messages". - // The action must be named "Move" in the Input Action Asset. - public void OnMove(InputValue value) - { - _moveInput = value.Get(); - } - - private void Update() - { - // Use _moveInput to control the player - transform.Translate(new Vector3(_moveInput.x, _moveInput.y, 0) * Time.deltaTime * 5f); - } -} -``` - -## Error Handling - -### Graceful Degradation - -**Asset Loading Error Handling:** -- When using Addressables or `Resources.Load`, always check if the loaded asset is null before using it. -```csharp -// Load a sprite and use a fallback if it fails -Sprite playerSprite = Resources.Load("Sprites/Player"); -if (playerSprite == null) -{ - Debug.LogError("Player sprite not found! Using default."); - playerSprite = Resources.Load("Sprites/Default"); -} -``` - -### Runtime Error Recovery - -**Assertions and Logging:** -- Use `Debug.Assert(condition, "Message")` to check for critical conditions that must be true. -- Use `Debug.LogError("Message")` for fatal errors and `Debug.LogWarning("Message")` for non-critical issues. -```csharp -// Example of using an assertion to ensure a component exists. -private Rigidbody2D _rb; - -void Awake() -{ - _rb = GetComponent(); - Debug.Assert(_rb != null, "Rigidbody2D component not found on player!"); -} -``` - -## Testing Standards - -### Unit Testing (Edit Mode) - -**Game Logic Testing:** -```csharp -// HealthSystemTests.cs - Example test for a simple health system. -using NUnit.Framework; -using UnityEngine; - -public class HealthSystemTests -{ - [Test] - public void TakeDamage_ReducesHealth() - { - // Arrange - var gameObject = new GameObject(); - var healthSystem = gameObject.AddComponent(); - // Note: This is a simplified example. You might need to mock dependencies. - - // Act - healthSystem.TakeDamage(20); - - // Assert - // This requires making health accessible for testing, e.g., via a public property or method. - // Assert.AreEqual(80, healthSystem.CurrentHealth); - } -} -``` - -### Integration Testing (Play Mode) - -**Scene Testing:** -- Play Mode tests run in a live scene, allowing you to test interactions between multiple components and systems. -- Use `yield return null;` to wait for the next frame. -```csharp -// PlayerJumpTest.cs -using System.Collections; -using NUnit.Framework; -using UnityEngine; -using UnityEngine.TestTools; - -public class PlayerJumpTest -{ - [UnityTest] - public IEnumerator PlayerJumps_WhenSpaceIsPressed() - { - // Arrange - var player = new GameObject().AddComponent(); - var initialY = player.transform.position.y; - - // Act - // Simulate pressing the jump button (requires setting up the input system for tests) - // For simplicity, we'll call a public method here. - // player.Jump(); - - // Wait for a few physics frames - yield return new WaitForSeconds(0.5f); - - // Assert - Assert.Greater(player.transform.position.y, initialY); - } -} -``` - -## File Organization - -### Project Structure - -``` -Assets/ -├── Scenes/ -│ ├── MainMenu.unity -│ └── Level01.unity -├── Scripts/ -│ ├── Core/ -│ │ ├── GameManager.cs -│ │ └── AudioManager.cs -│ ├── Player/ -│ │ ├── PlayerController.cs -│ │ └── PlayerHealth.cs -│ ├── Editor/ -│ │ └── CustomInspectors.cs -│ └── Data/ -│ └── EnemyData.cs -├── Prefabs/ -│ ├── Player.prefab -│ └── Enemies/ -│ └── Slime.prefab -├── Art/ -│ ├── Sprites/ -│ └── Animations/ -├── Audio/ -│ ├── Music/ -│ └── SFX/ -├── Data/ -│ └── ScriptableObjects/ -│ └── EnemyData/ -└── Tests/ - ├── EditMode/ - │ └── HealthSystemTests.cs - └── PlayMode/ - └── PlayerJumpTest.cs -``` - -## Development Workflow - -### Story Implementation Process - -1. **Read Story Requirements:** - - - Understand acceptance criteria - - Identify technical requirements - - Review performance constraints - -2. **Plan Implementation:** - - - Identify files to create/modify - - Consider Unity's component-based architecture - - Plan testing approach - -3. **Implement Feature:** - - - Write clean C# code following all guidelines - - Use established patterns - - Maintain stable FPS performance - -4. **Test Implementation:** - - - Write edit mode tests for game logic - - Write play mode tests for integration testing - - Test cross-platform functionality - - Validate performance targets - -5. **Update Documentation:** - - Mark story checkboxes complete - - Document any deviations - - Update architecture if needed - -### Code Review Checklist - -- [ ] C# code compiles without errors or warnings. -- [ ] All automated tests pass. -- [ ] Code follows naming conventions and architectural patterns. -- [ ] No expensive operations in `Update()` loops. -- [ ] Public fields/methods are documented with comments. -- [ ] New assets are organized into the correct folders. - -## Performance Targets - -### Frame Rate Requirements - -- **PC/Console**: Maintain a stable 60+ FPS. -- **Mobile**: Maintain 60 FPS on mid-range devices, minimum 30 FPS on low-end. -- **Optimization**: Use the Unity Profiler to identify and fix performance drops. - -### Memory Management - -- **Total Memory**: Keep builds under platform-specific limits (e.g., 200MB for a simple mobile game). -- **Garbage Collection**: Minimize GC spikes by avoiding string concatenation, `new` keyword usage in loops, and by pooling objects. - -### Loading Performance - -- **Initial Load**: Under 5 seconds for game start. -- **Scene Transitions**: Under 2 seconds between scenes. Use asynchronous scene loading. - -These guidelines ensure consistent, high-quality game development that meets performance targets and maintains code quality across all implementation stories. -==================== END: .bmad-2d-unity-game-dev/data/development-guidelines.md ==================== diff --git a/dist/expansion-packs/bmad-2d-unity-game-dev/agents/game-sm.txt b/dist/expansion-packs/bmad-2d-unity-game-dev/agents/game-sm.txt index 7214856a..e192da71 100644 --- a/dist/expansion-packs/bmad-2d-unity-game-dev/agents/game-sm.txt +++ b/dist/expansion-packs/bmad-2d-unity-game-dev/agents/game-sm.txt @@ -50,7 +50,6 @@ activation-instructions: - The agent.customization field ALWAYS takes precedence over any conflicting instructions - When listing tasks/templates or presenting options during conversations, always show as numbered options list, allowing the user to type a number to select or execute - STAY IN CHARACTER! - - 'CRITICAL RULE: You are ONLY allowed to create/modify story files - NEVER implement!

For example, adding a logging framework as a last story of an epic, or at the end of a project as a final epic or story would be terrible as we would not have logging from the beginning. + elicit: true + examples: + - "Epic 1: Unity Foundation & Core Systems: Project setup, input handling, basic scene management" + - "Epic 2: Core Game Mechanics: Player controller, physics systems, basic gameplay loop" + - "Epic 3: Level Systems & Content Pipeline: Scene loading, prefab systems, level progression" + - "Epic 4: Polish & Platform Optimization: Performance tuning, platform-specific features, deployment" + + - id: epic-details + title: Epic {{epic_number}} {{epic_title}} + repeatable: true + instruction: | + After the epic list is approved, present each epic with all its stories and acceptance criteria as a complete review unit. + + For each epic provide expanded goal (2-3 sentences describing the objective and value all the stories will achieve). + + CRITICAL STORY SEQUENCING REQUIREMENTS: + + - Stories within each epic MUST be logically sequential + - Each story should be a "vertical slice" delivering complete functionality aside from early enabler stories for project foundation + - No story should depend on work from a later story or epic + - Identify and note any direct prerequisite stories + - Focus on "what" and "why" not "how" (leave technical implementation to Architect) yet be precise enough to support a logical sequential order of operations from story to story. + - Ensure each story delivers clear user or business value, try to avoid enablers and build them into stories that deliver value. + - Size stories for AI agent execution: Each story must be completable by a single AI agent in one focused session without context overflow + - Think "junior developer working for 2-4 hours" - stories must be small, focused, and self-contained + - If a story seems complex, break it down further as long as it can deliver a vertical slice + elicit: true + template: "{{epic_goal}}" + sections: + - id: story + title: Story {{epic_number}}.{{story_number}} {{story_title}} + repeatable: true + instruction: Provide a clear, concise description of what this story implements.
