Handles API - Scene View Text & Lines | Unity Tutorial

In this tutorial I'll show how I created the editor script that drew informational distance text and the path a NavMeshAgent would take to move to a specific target, highlighting the closest target in the Scene View in AI Series Part 12.
Specifically, in this video I use the Handles API: Handles.Label and Handles.DrawLine functions to draw lines and text between the NavMeshAgent's current position and points found on the NavMeshPath to a specified target object. We'll also handle if the NavMeshAgent cannot find a valid path to the specified target.
