We won't be diving into the specifics of the AStar Algorithm, but we will use it in our game to plan the paths of AI characters.

A tool for Unity

Luckily, a great tool to make the process of implementing AStar in Unity already exists, and it is also freely available. It can be downloaded here: http://arongranberg.com/astar/download.

After extracting the downloaded archive, double-click on the package in order to import the necessary files inside Unity. The following screen should appear, and then click on Import:
