How to map the controls to a controler (OUYA)?

Kirb

This is more of a Unity question than an ORK question! :P

I'd take a look on the unity forums for mapping input to the controllers.

As a side note, since Ouya isn't really an officially supported export for Unity, you'd need to look through resources like:

https://github.com/ouya/docs/blob/master/unity.md#example-scenes-1

if you plan to port to it.
