2D platform engine in unity part 12 - Patrolling AI

A while back my friend Steve asked me if he could use my old platformer engine for a game he wanted to do! I was very happy to see it come to use!

The engine is open source btw, and can be found here: https://github.com/Tommislav/unity2dPhysics.

But tonights short coding session involved a fix to the physics system to detect when someone is “over a ledge”. The hedgehog enemy in the image above will switch patrol direction if either hitting a wall, or getting over a ledge.

The guy with the white hat is my old AI, who just moves in random directions for a random amount of time. In my last post he was a red box. Steve has drawn and animated him quite nice!
