Building Games in Rust with Legion ECS

Game development in Rust requires a shift from traditional object-oriented patterns to data-driven architectures. Understanding the Entity Component System (ECS) model is the key to writing clean, maintainable, and highly performant game code. This text-based course guides you from the fundamental concepts of ECS to implementing a fully structured game state using the Legion library. You will learn how to design data structures that leverage Rust's memory safety and speed for game logic through clear written explanations and practical code examples. What you'll learn: - Understand the core principles of Entity Component System (ECS) architecture and how it differs from traditional object-oriented programming. - Configure and install the Legion library in your Rust projects using Cargo. - Create and manage entities, attach components, and query data efficiently. - Write modular systems to handle game logic, physics, and state updates. - Apply modern Rust features like type safety and smart pointers to ensure robust game architectures. - Structure a clean, maintainable game loop that scales as your project grows. You will start by exploring foundational ECS terminology and architectural concepts. From there, you will progress through written explanations and practical code snippets to build, query, and optimize your game systems step-by-step. This course is designed for beginner Rust developers and aspiring game creators who want to learn structured game programming. No prior experience with game engines or ECS libraries is required.
