A* Euclidean Graph Pathfinding System (without NavMesh | UE5)

Ever wanted to create a custom pathfinding system in Unreal Engine 5 that doesn't rely solely on the default NavMesh? In this tutorial, we dive deep into building a custom A (A-Star) Pathfinding System* from scratch using C++ and Blueprints+, with Euclidean distance for accurate, straight-line pathfinding in a graph-based world. Whether you are making a RTS, a turn-based tactical game, or just want to understand how AI finds the shortest path, this video covers the logic, the math, and the implementation.
