Syntax

class FInputDeviceScope

Remarks

Context scope that indicates which IInputDevice is currently being handled. This can be used to determine hardware-specific information when handling input from FGenericApplicationMessageHandler subclasses. This is generally set during SendControllerEvents or Tick and is only valid on the game thread.

Variables

	Name	Description
int32	HardwareDeviceHandle	A system-specific device id, this is not the same as controllerId and represents a physical device instead of logical user.
FString	HardwareDeviceIdentifier	Logical string identifying the hardware device.
IInputDevice &#...	InputDevice	The specific InputDevice that is currently being polled.
FName	InputDeviceName	Logical name of the input device interface. This is not translated but is platform-specific

Constructors

	Name	Description
	FInputDeviceScope()	Cannot be copied/moved
	FInputDeviceScope ( const FInputDeviceScope& )
	FInputDeviceScope ( FInputDeviceScope&& )
	FInputDeviceScope ( IInputDevice* InInputDevice, FName InInputDeviceName, int32 InHardwareDeviceHandle, FString InHardwareDeviceIdentifier )	Constructor, this should only be allocated directly on the stack
