Learn how to move characters and objects from point A to B with this introduction to pathfinding in Unity 5. This training focuses on pathfinding in the 2D world: programming simple ways to connect different locations in 2D games. Jesse Freeman starts by explaining the data structures (graphs and nodes) and the A* pathfinding algorithm: the technology that makes traversal of 2D games possible. Then he shows you how to connect paths in a 2D map, and find the fastest path between two points. You'll also build a simple demo map to illustrate and test the pathfinding logic.
