This is an old version, I am in the process of creating an updated one.

Unity3D - AI Patrol With Widget - Unity Version: 2021.3.0f1

Using a custom editor window, one can quickly create paths for NPCs to walk on through a game enviroment in Unity.

Using Unity's Widgets, you can also visually see the path and node numbers while in the editor.

These example images have a patrol that has 8 points the traversingObject walks to/around.

The program as well toggles a boolean within the traversingObject's Animator called "shouldMove" to toggle its' walk animation on/off.

If "Should Loop" is toggled off, the traversingOject will walk through the patrol in the opposite direction. If toggled on, the widget will show a new line connecting the ends of the patrol, showing it as a new part of the patrol path.
