ffi-xinput

ffi-xinput is an FFI wrapper that can be used to interface with the XInput controller library for Windows. It can read the state of any controller hooked up to a system that supports XInput, or activate it's rumble feature.

gem install ffi-xinput

Enable XInput support in your project:

require "ffi-xinput"

Create a new XInput controller instance:

xinput = XInput.new(controller_id) #id can be 0-3

Check if a controller is connected:

xinput.connected?
XInput.connected?(controller_id)

Get the state of a controller (returns a hash containing the state of all controller buttons/axis):

xinput.state
XInput.state(controller_id)

Set the vibration level for the left/right motor:

xinput.vibrate(left_motor, right_motor) #values can range from 0.0 to 1.0
XInput.vibrate(controller_id, left_motor, right_motor)
