What Will I Learn?

• Write procedural dungeon generation algorithms to create randomized roguelike environments in Unity.
• Use C# to solve common game development challenges, including grid-based level design and AI behavior.
• Implement a 2D bitwise tilemap system for automatic tile placement and rounded edge generation.
• Develop a simplified enemy pathfinding system using flood fill logic to navigate around obstacles.
• Create a dynamic Fog of War system that reveals explored areas and manages player visibility.

Requirements

• Basic computing experience – Comfort with general software navigation and file management.
• Experience with Unity – Prior exposure to the Unity game engine is recommended.
• Basic knowledge of C# programming – Understanding of variables, loops, and functions is required.
• 2D graphics editing experience is helpful – While not required, familiarity with Photoshop, GIMP, or similar software will be useful.

Target audience

• Unity developers looking to create randomly generated 2D dungeons.
• C# programmers who want to explore procedural level design and AI movement systems.
• Roguelike game enthusiasts eager to learn how procedural dungeons are built in Unity.
• Indie game developers seeking efficient ways to generate tile-based levels dynamically.
