Unity 5 2D: Introduction to Pathfinding

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.

Topics include:

What is A\*?  

Adding node classes and properties  

Storing and indexing graph nodes  

Building the search class  

Traversing the nodes  

Searching adjacent nodes  

Testing the search  

Building a test map  

Creating and coloring a grid
