I decided to play around with navigation meshes in Unity this weekend to learn a little more about how they work. So far I'm just creating a very simple test with this little test environment, a player, a goal, some obstacles, and some zombie cubes that want to rip the polygons right off the players mesh!!! It was really simple to hook everything up and get it running. So I decided to grab the joystick controls from the Unity Standard Assets (Mobile) package and build this test for mobile. Tried it out on my Kobo Arc and it all seems to work great! I haven't done any profiling, but it seems to be running just fine. My next test will be with a mesh that is not flat. I will try out some terrain type meshes and see how Unity's navigation meshes work.
