unity-ai-game-creator – Other skill for AI agents

Unity AI Game Creator

Overview

This skill transforms a raw game concept into a fully structured Unity development plan with specifications for assets, scenes, music, scripts and build validation. A plan or prompt kit is not a completed Unity project or verified build. It guides the agent through a 5-phase pipeline — from extracting core game dimensions to producing ready-to-use AI prompts for every asset category — using the latest Unity 6+ features and AI tooling ecosystem. Unlike generic Unity reference skills, this skill is workflow-driven: the user provides an idea, and the agent delivers a complete, actionable game development roadmap.

When to Use This Skill

• Use when a user describes a game idea and wants a complete development plan
• Use when generating AI prompts for 3D models, textures, music, sound effects, or UI assets
• Use when setting up a new Unity project from scratch with modern architecture
• Use when creating Scene Blueprints from a concept description
• Use when building a Game Design Document (GDD) from a rough idea
• Use when leveraging Unity AI Assistant, MCP server, or external AI tools in a game workflow
• Use when planning monetization, performance budgets, or app store deployment

How It Works

Master Pipeline

Use these phases for the requested scope. Planning does not authorize paid generation, package/MCP installation, telemetry, store publication or submission; perform those only when the user authorizes the action and target.

PHASE 1: IDEATION ──▶ PHASE 2: BLUEPRINT ──▶ PHASE 3: GENERATION ──▶ PHASE 4: ASSEMBLY ──▶ PHASE 5: DEPLOYMENT
  Game Brief            GDD + Scenes           AI Prompts + Assets     Project Setup          Build + Store
  Genre Analysis        Architecture           Scripts + Audio         Core Systems           QA + Submit
  Scope Assessment      Scene Blueprints       Voice + UI              Polish + Juice         Analytics

Phase 1: Ideation & Deep Analysis

Extract and clarify these dimensions from the user's game idea. Ask only for what is ambiguous — infer the rest from context.

| Dimension | What to Extract | If Unclear |

|-----------|----------------|------------|

| Genre | Primary + secondary genre blend | Suggest 3 genre combinations |

| Platform | Mobile, PC, Console, WebGL, VR/AR | Recommend based on scope |

| Perspective | 2D, 2.5D, 3D, Top-down, Side-scroll, FPS, TPS | Infer from genre |

| Art Style | Realistic, Stylized, Pixel, Low-poly, Anime, Painterly | Suggest 3 options |

| Core Loop | The 30-second repeating gameplay action | Identify from description |

| Target Audience | Age range, gamer profile, platform habits | Recommend based on genre |

| Session Length | Average play session duration | Infer from platform + genre |

| Monetization | Free-to-play, Premium, Hybrid | Recommend based on platform |

| Scope | Solo dev, small team, studio | Ask if not obvious |

| Timeline | MVP in weeks, full release target | Suggest realistic milestones |

Also provide:

1. Top 3 Reference Games — What they do well, what the user can learn

2. Market Gap Hypothesis — What opportunity to research; distinguish evidence from assumptions

3. Core Differentiator — The one unique thing about this game

4. Risk Assessment — Technical and market risks with mitigations

Illustrative Scope Calibration (not delivery estimates):

| Scope | Timeline | Team Size | Feature Budget |

|-------|----------|-----------|----------------|

| Prototype | 1–2 weeks | Solo | Core loop only |

| Vertical Slice | 4–6 weeks | Solo–2 | 1 complete level + polish |

| MVP | 8–12 weeks | 2–4 | 3–5 levels + save + UI |

| Full Release | 16–24+ weeks | 3–8 | Complete content + multiplayer |

Phase 2: Blueprint & Design

Game Design Document (GDD)

Generate a structured GDD covering:

1. Executive Summary — Elevator pitch, genre, USPs

2. Gameplay — Core loop diagram, progression, abilities, win/loss, difficulty curve

3. World & Narrative — Setting, characters, level structure

4. Art Direction — Visual style, color palette (hex codes), reference descriptions, UI/UX style

5. Audio Direction — Music style per scene, SFX categories, voice needs

6. Technical Spec — Unity version, render pipeline, performance budgets, SDKs

7. Monetization Strategy — Revenue model, IAP design, ad placement

8. Development Roadmap — Phases, milestones, feature priority matrix, risk register

Scene Blueprints

For each scene, produce a hierarchy covering:

• Environment — Ground/terrain, skybox, lighting setup, props with positions
• Interactive Objects — Behavior on interaction
• Characters / NPCs — AI behavior, patrol paths, dialogue triggers
• UI Overlay — HUD elements, contextual prompts
• Audio Layers — Background music (mood, tempo, loop point), ambient SFX, trigger SFX
• Camera Setup — Type (Cinemachine/Fixed/Follow), behavior configuration
• Systems Active — Save checkpoints, spawners, particle effects

Architecture Blueprint

Provide recommended project folder structure:

Assets/_Project/
├── Scripts/ (Core, Gameplay, UI, Data, Audio, Utilities)
├── Prefabs/ (Characters, Environment, UI, VFX)
├── Scenes/
├── Art/ (Models, Textures, Materials, Animations, UI_Assets)
├── Audio/ (Music, SFX, Ambience)
├── ScriptableObjects/
└── Resources/

Phase 3: AI-Powered Asset Generation

For every asset category, provide ready-to-use prompts for the best current AI tools.

3D Model Prompts

Recommend tools dynamically (Meshy.ai, Tripo3D, Rodin, Unity AI Assistant) and generate prompts including:

• Asset name, art style, gameplay purpose
• Polygon budget, texture resolution, PBR maps needed
• Animation-ready flag, scale reference
• Unity import settings (scale factor, normals, animation type, material handling)

Texture & 2D Asset Prompts

Recommend tools (Leonardo.ai, Midjourney, DALL·E, Unity AI Assistant) and generate prompts including:

• Texture type (seamless tile, sprite, UI element, concept art)
• Resolution, style, tiling requirements, PBR maps
• Unity import settings (texture type, filter mode, compression, max size)

Music Prompts

Recommend tools (Suno, Soundraw, Sonauto) and generate prompts including:

• Track name, scene context, mood, tempo (BPM), duration
• Instruments, reference tracks, loop points, dynamic layers
• Unity import settings (format, load type, compression, loop config)

Sound Effects Prompts

Recommend tools (ElevenLabs, OptimizerAI/SFX Engine) and generate prompts including:

• SFX name, category, gameplay context, duration
• Variation count, characteristics
• Unity import settings (format, load type, 3D sound config, variation arrays)

Voice & Narration Prompts

Recommend tools (ElevenLabs, Play.ht, Coqui) and generate prompts including:

• Character name, voice profile, dialogue line, emotion, context

UI/UX Asset Prompts

Generate specifications for Unity UI Toolkit or AI image generation including:

• Element name, screen context, visual style
• States (normal, hover, pressed, disabled)
• Dimensions, anchor behavior, animation descriptions

Phase 4: Assembly & Development

Project Initialization Checklist

• Unity version (recommend latest Unity 6 LTS)
• Render pipeline (URP for mobile/stylized, HDRP for high-fidelity, URP 2D Renderer or Built-in for 2D depending on requirements)
• Build settings, player settings (color space, scripting backend, API compatibility)
• Essential packages (Input System, Cinemachine, TextMeshPro, Addressables, Unity AI Assistant)
• Git LFS configuration for large assets

Development Order (Week-by-Week)

1. Foundation — Project setup, GameManager, event system, scene management, input config

2. Core Gameplay — Player controller, camera, core loop, basic enemies

3. Content & Systems — Level building, UI system, audio manager, save/load

4. Polish & Feedback — VFX/juice, progression, tutorial, settings

5. Platform & Release — Profiling, monetization, analytics, platform polish, submission

Script Architecture Patterns

• GameManager → Singleton or Service Locator
• Events → Observer Pattern (C# events + ScriptableObject Events)
• Save System → Versioned JSON, validated loading, atomic writes and recovery; encryption only with a defined threat/key-management model
• Object Pooling → Generic pool for bullets, enemies, VFX
• State Machine → Player states, game states, enemy AI
• Audio → Singleton with Audio Mixer Groups
• UI → UI Toolkit with MVVM or event binding
• Scene Loading → Addressables + async with progress
• Input → New Input System with Action Maps

Unity AI Assistant & MCP Integration

• Verify current Unity AI Assistant package, editor compatibility, account and pricing before setup
• MCP server configuration for external IDE/agent control
• Example in-editor prompts for scene manipulation, scripting, profiling
