How do I make a simulation that could be edited?

Question

I want to make a 2D top-down simulation of a automatic lawnmower that cuts grass with visible sensors around it, I also want to be able to map the grass. Ive made a platformer before so I know the basics I’m just stumped on these parts.

Which parts exactly? You need to be more specific.

Okay, so I’m trying to figure out how the sensors should interact with the grass. Should I just consider the grass as an object or something else? And with the editor I’m struggling with how I’m supposed to build it.
