C# Procedural Random Dungeon Generator in Unity 3D & Blender

Learn interior-only random dungeon generation using a geomorph method that connects modular rooms and hallways in C#

Created by: Billy McDaniel

What Will I Learn?

• Develop a procedural dungeon generator that assembles rooms and hallways dynamically using C#.
• Create modular room and hallway prefabs in Blender and import them into Unity for use in procedural generation.
• Write C# scripts to connect rooms at runtime, ensuring seamless and randomized dungeon layouts.
• Implement backtracking and collision detection logic to refine dungeon structure and prevent placement issues.
• Spawn interactive objects, doors, and exit triggers dynamically to enhance level variety.
• Optimize procedural generation performance for smooth gameplay and resource efficiency.

Requirements

• Basic familiarity with Unity – You should understand how to create projects, manage GameObjects, and use prefabs.
• Some experience with C# scripting – Prior programming knowledge is required, as this course focuses heavily on procedural logic.
• Blender experience is helpful but not required – Pre-made 3D models are included, but an understanding of Blender will help if you want to customize or expand your modular assets.
• A willingness to work with code – This course involves structured, logic-driven programming to build a complete procedural system.

Target audience

• Unity game developers looking to create randomized environments for roguelike, RPG, or adventure games.
• C# programmers interested in learning how to build complex procedural systems from scratch.
• Indie game developers who want to integrate unique, dynamically generated levels into their projects.
• Developers working with modular 3D assets who want to generate seamless, connected environments.
• This course does not cover beginner-level Unity or C# basics—students should already have some experience in these areas before enrolling.
