SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Unity projects often grow into tangled MonoBehaviour scripts with hidden execution-order bugs and unclear responsibilities. This Skill provides structured architecture guidance before you write structural code, helping you choose the smallest architecture that fits your project scope. ## Core Features & Use Cases - Scoped Architecture Planning: Recommends 3-7 modules with clear responsibilities based on whether the project is a prototype, small game, or long-lived product. - Execution Order & Guard Guidance: Explains how to make startup order explicit with a single Bootstrap script and how to write guard clauses in Update methods to prevent null-data bugs. - Layered Separation Advice: Defines boundaries between scene/bootstrap, gameplay logic, data/config assets, and presentation layers, including when to use ScriptableObjects versus plain C# classes. - Use Case: Before building a new gameplay system, ask for an architecture plan and receive a module breakdown, scene composition plan, data ownership rules, and a do-now/skip-now list that avoids over-engineering. ## Quick Start Ask the assistant to plan the architecture for your Unity game, describing your project scope and core gameplay loop.

Frequently Asked Questions about unity-architecture

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I structure a Unity project architecture?▼

Start by identifying your project scope (prototype, small game, or long-lived), then define the core loop and minimum runtime systems. Separate scene/bootstrap, gameplay logic, data assets, and presentation into 3-7 modules with one-line responsibilities each.

How to fix Unity script execution order problems?▼

Use a single Bootstrap script with [DefaultExecutionOrder(-10000)] as the only entry point that initializes managers explicitly. Prefer pull-based access where subscribers call GetValue() instead of publishers pushing data during Awake.

When should I use ScriptableObjects in Unity?▼

Use ScriptableObjects for authored configuration and shared static data, not as a default dump for runtime state. Keep reusable gameplay rules in plain C# classes and use thin MonoBehaviours only as composition bridges.

Why does my Unity Update method run with null data?▼

Update runs regardless of whether dependencies are ready, so add guard clauses at the top: check initialization flags, null data sources, and pause state before doing real work. Missing guards cause silent state corruption instead of safe no-ops.

When should I avoid heavy architecture frameworks in Unity?▼

Avoid framework-heavy architecture for prototypes and small games where iteration speed matters most. Prefer a small architecture that can grow, explicit dependencies, and simple module boundaries over textbook SOLID layering.
