Procedural Dungeon Generation: Diablo-Style PCG in Unity and C#

Procedural content generation (PCG) is the backbone of replayable game design, allowing developers to build endless variations of game worlds without manual modeling. If you have ever wondered how classic action RPGs like Diablo generated their iconic, atmospheric layouts, the secret lies in elegant grid-based algorithms. In this text-based course, you will unpack the core logic behind classic PCG dungeon generation. You will transition from understanding basic grid mechanics to writing clean, modular C# code in Unity that builds randomized, connected, and fully navigable dungeon layouts from scratch. What you'll learn: - Understand the foundational concepts of procedural content generation and grid-based map systems. - Implement room placement algorithms to randomly distribute and size dungeon chambers. - Apply corridor connection logic to ensure every room is reachable without manual design. - Write clean, modular C# code utilizing modern collection types and efficient spatial querying. - Configure tilemap generation in Unity to procedurally instantiate walls, floors, and doorways. - Practice debugging techniques for procedural layouts to prevent isolated rooms and broken paths. This course begins with essential definitions of PCG and grid structures before guiding you step-by-step through the logic of room generation, connectivity, and tile mapping. You will read thorough explanations, study clean code snippets, and learn how to structure your generation systems for performance and flexibility. Designed for beginner game developers and programmers with a basic grasp of C# and Unity who want to dive into procedural systems, this course requires no advanced mathematics or prior PCG experience.
