2D Path finding?

I am not sure if this is the right place to ask this. Anyway is there an easy way to do AI path finding in 2D mode? Is there something like the NavMesh + navigation that is in 3D mode? If not is it possible to flip the NavMesh so that it works on the same axis as 2D mode?

A* is generally the best way of doing pathfinding. If you’re up to it you could program your own A* implementation based on this tutorial (that’s what I would do) Joseph Hocking's website

Otherwise, you could try the existing A* Pathfinding Project: A* Pathfinding Project

here are examples using that in a 2D game:
