// Custom Action by HendrikB
// You can find me on Playmaker forums for suggestions, bugs, fixes or just to say hello :)
// Script allows you to check if controllers are detected, and if so, if it is setup as right-handed or left-handed
// You need the Oculus Utilities for Unity package
// Then find the OVRManager script that comes with Oculus Utilities package and add it to any gameobject in your scene.

    // Remember to add OVRManager script anywhere in the scene before OVRInput will work.
