Unity AI Game Creator

Overview

This skill transforms a raw game concept into a fully structured Unity development plan with AI-generated assets, scenes, music, scripts, and deployment-ready builds. 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

Execute these phases in order. Each phase produces concrete deliverables before advancing.

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.

Also provide: 1. Top 3 Reference Games — What they do well, what the user can learn 2. Market Gap — What opportunity exists that competitors miss 3. Core Differentiator — The one unique thing about this game 4. Risk Assessment — Technical and market risks with mitigations

Scope Calibration:

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
