Game Development in Elixir: Designing Battle Systems and Hit Points

Turn-based game mechanics offer an excellent way to master functional programming concepts. Applying Elixir's unique architecture to game logic like hit points and enemy behaviors helps you think like a true functional developer. This text-only course guides you through designing robust battle systems from scratch. You will transition from writing basic Elixir syntax to structuring clean, maintainable game logic using functional principles, immutable state, and modular design. What you'll learn: - Understand the fundamentals of immutable state and how to model game entities like players and enemies. - Implement hit point systems and combat math using pattern matching and guard clauses. - Use Elixir behaviors to define consistent rules for different enemy types and actions. - Manage turn-based game loops and state transitions cleanly without mutating data. - Write unit tests with ExUnit to verify battle logic and edge cases. You will begin with core Elixir concepts and foundational state modeling before progressing to battle mechanics, module behaviors, and automated testing. This course is designed for beginners to Elixir or functional programming who want a practical project to solidify their skills, with no prior game development experience required.
