How to create a "wall enemy"??

Hi, I’m looking for a type of enemy that follows a platform like the beetle in the gif but I can’t do it. Any suggestions??

i think you need the help of kurt dekker, he has a good project with this mechanic showcased

I believe what Perth means is this project (source in comments):

But I don’t think that’s what is going on in the GIF above.

For one, the left two beetles follow around the end of a platform but the other doesn’t.

For two, the right beetle doesn’t even use the whole platform.

I think the GIF above is just simple authored patrol paths put on top of a scene of tiles or sprites, and code to follow those paths.
