Drag a 3d Rigidbody from anywhere on screen IS IT POSSIBLE?

I've searched all over the internet and can't find anything I'm looking for, there are stuff on transform.position but that isn't what I'm looking for. Is it possible to drag a 3d rigidbody object around a certain space from dragging mouse anywhere on screen? I'm working for mobile right now and the perfect example for my result is from a game called Fluffy Fall on the android play store.
