"Gamepad" Input example for Wekinator, e.g. for Xbox 360 controller
// Gamepad_Eyes_OSC: demo of using game controller for OSC input.
// Uses the two thumb-sticks and either the left or right bumper buttons.
//
// Peter Lager maintains the Game Control Plus library (for Processing),
// which provides control data for joysticks and other game controllers
// ...such as my Xbox 360 controller.
//
// This is a quick mash-up using Lager's Gcp_gamepad animated eyes example code,
// (which is in the GCP library: In Processing, go to File > Examples..., then Contributed Libraries > Game Control Plus)
// and Rebecca Fiebrink's Simple_Mouse_DraggedObject_2Inputs example code for Wekinator.
//
// Required Processing libraries: Game Control Plus, oscP5. Also needs Lager's file "data/gamepad_eyes" text file from his example.
//
// See Lager's website & videos at http://lagers.org.uk/gamecontrol/ for more info.
//
// Mashed by @drscotthawley
// Demo video: https://youtu.be/VZ73RlDlnNQ
// (Controller animation provided by 360 Controller for Mac driver, https://github.com/360Controller/360Controller/releases)
