Elixir Structs for Game Development: Modeling Coordinates

Building games requires a solid foundation for representing spatial data like grid positions, board coordinates, and map locations. In Elixir, leveraging structs is the key to creating predictable, type-safe, and self-validating game entities. This text-based course guides you through the process of defining, validating, and manipulating coordinate systems using Elixir structs. You will transition from using primitive data types to designing robust, encapsulated domain models that prevent common bugs in game logic. What you'll learn: Understand the fundamentals of Elixir structs and how they differ from standard maps; Define coordinate structs with default values and compile-time enforcement rules; Implement data validation using helper functions to ensure row and column integrity; Apply pattern matching to extract and manipulate coordinate values efficiently; Use type specifications to document and enforce your coordinate data structures; Practice modeling coordinate transformations, such as translations and movement boundaries. You will start with foundational definitions of structs and functional data modeling, then progressively build a robust coordinate system step-by-step through clear, written explanations and structured code snippets. This course is designed for beginner Elixir developers and aspiring game creators who want to learn structured data modeling, requiring no prior game development experience.
