Syntax
Parameters
This method has no parameters.Return value
Type: uint32_t The number of touch surfaces on the device, or 0 if the device has no touch surfaces.Remarks
A touch surface is an area of the device that reports touch contacts, such as the touchpad on a DualSense or DualShock 4 controller. Devices with at least one touch surface includeGameInputKindTouch in the value returned by IGameInputDevice::GetSupportedInput.
Touch surfaces are identified by a zero-based index that’s less than the value returned by this method. Use the index to get a description of the surface by calling IGameInputDevice::GetTouchSurfaceInfo, and to read the contacts on the surface from a reading by calling IGameInputReading::GetTouchSurfaceState.
The number of touch surfaces doesn’t change for the lifetime of the device object.
Touch support depends on the device and the platform.
