Type String Object InputAxis Revision Current Public Release (2017.3068) Keywords device, input, axis, descriptor
Provides a human-readable string (assigned by Corona) which can be used to uniquely identify one axis input belonging to one device. This descriptor string is intended to be used by applications that set up key and axis bindings with a particular device, such as the first joystick connected to the system.
This descriptor string key is generated based on the device's descriptor and the axis number. For example, the first 2 axes belonging to one joystick will be named
Joystick 1: Axis 1 and
Joystick 1: Axis 2.
