XRInputSource.gamepad

The read-only XRInputSource property gamepad returns a Gamepad object describing the state of the buttons and axes on the XR input source, if it is a gamepad or comparable device. If the device isn't a gamepad-like device, this property's value is null.

The Gamepad instance returned behaves as described by the Gamepad API. However, there are a few things to note:

• XRInputSource Gamepad instances are not included in the array returned by navigator.getGamepads(). Gamepads are strictly associated with the WebXR hardware and are not general-purpose gaming devices.
• Gamepad.id is an empty string ("")
• Gamepad.index is -1
• Gamepad.connected is true until the XRInputSource is removed from the list of active XR input sources or the XRSession is ended.
• If an axis reported by Gamepad.axes represents an axis of a touchpad, the value is 0 when the associated GamepadButton.touched property is false.
• Gamepad.mapping returns "xr-standard".

Examples
