Functional Game Modeling in Elixir with MapSet

Building robust, state-driven systems is a core skill for any developer entering the world of functional programming. Modeling grid-based board games offers an excellent, practical sandbox to understand how Elixir manages state, coordinates, and collections without mutating data. By completing this written course, you will transition from basic syntax to structuring real-world game logic using functional paradigms. You will learn to represent coordinates, manage board layouts, and implement complex rules using Elixir's native data structures. What you'll learn: - Understand foundational functional concepts, including immutable state and pattern matching for game rules. - Model board coordinates and game elements using Elixir structs and modern type specifications. - Utilize the MapSet module to efficiently track positions, check for overlapping elements, and update game states. - Implement core game mechanics like coordinate guessing, hit detection, and tracking targeted areas. - Structure clean, maintainable Elixir code by separating pure logical operations from state management. The course starts with essential terminology and the basics of functional data modeling before walking you through the step-by-step implementation of grid coordinates and set mathematics. You will read structured explanations, analyze clear code snippets, and reinforce your learning through written exercises. This course is designed for beginner Elixir developers who want to apply functional programming concepts to practical software design, with no advanced prerequisites required.
