How do I trigger a next-to-edge animation?

So I want to make an animation to use whenever you're near the edge of a platform, floor, or whatever solid you're sitting on top, kinda like you're lossing your stability. We're talking about a 2D simple platformer.

The problem is not creating the animation, is the triggers.

How do I set the triggers for this? Can't come up with proper events to make it happen.

Thank you!!

Place helper objects on the corners ? On overlap .. play ..

In this post the placing of those helpers is automated.

Use arrows to move the character.

That would be a great idea if it wasn't such a pain to place it all over a level, for each level, for each solid.

It can be automated with 1 included event sheet. Did you see the post i linked to ?

I can't trigger those events. My "ground" is a whole level tilemap that includes also walls.
