About this course

To create intelligent, navigating characters in games, you need to understand the mechanics behind pathfinding rather than relying solely on built-in black-box tools. Writing your own navigation systems gives you complete control over how entities move and interact with your game world. This text-based course guides you through the foundational mathematics and programming logic required to build custom search algorithms in Unity. You will transition from understanding basic graph theory to writing optimized pathfinding code, including the industry-standard A* algorithm, using clean C# architecture. What you'll learn: - Understand the foundational terminology of graph theory, including nodes, edges, weights, and grid-based representations. - Implement classic search algorithms from scratch, starting with Breadth-First Search and advancing to Dijkstra's algorithm. - Build a custom, optimized A* pathfinding system in Unity to calculate efficient paths across game levels. - Develop a custom binary heap priority queue in C# to maximize search algorithm performance. - Apply clean architecture and separation of concerns to decouple your pathfinding logic from game rendering. - Parse level layout data from text files and texture maps to dynamically generate game grids. The course begins with core definitions and the mathematics of graph representation, gradually guiding you through implementing progressively complex algorithms in structured, readable C# code. This course is designed for aspiring game developers and programmers who want to learn the mechanics of game AI and pathfinding from the ground up, with no prior algorithm experience required. Start building your own custom navigation systems and elevate your game programming skills today.
