## What it is
A collection of small Unity demo projects illustrating well-known software design patterns (Observer, State, Object Pooling, MVC/MVP, Factory, Command) to accompany Unity's ebook 'Level up your code with game programming patterns'. It serves as practical companion code for experienced Unity developers learning cleaner, more maintainable C# architecture.

## Use cases
- learn design patterns in Unity
- see object pooling example for C# scripts
- study observer pattern for modular game code
- example of state pattern in a Unity game
- learn MVC and MVP in Unity projects
- companion code for Unity game programming patterns ebook

## When to choose
- you are an experienced Unity developer wanting concrete pattern implementations
- you are reading the Unity ebook and want runnable examples
- you want reference code for SOLID principles in game development

## When to avoid
- you need a production-ready library or framework to drop into your project
- you are a beginner needing step-by-step tutorials rather than demos
- you need a permissively licensed codebase (no license is specified)

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: tutorials, programming-languages
- platform: game-engine, cross-platform
- tags: unity, design-patterns, csharp, ebook, sample-project, solid-principles, object-pooling, observer-pattern, state-pattern, mvc, game-development
