API reference
FingerPinchGrabAPI Class
Extends IFingerAPI
This IFingerAPI uses an advanced calculation for the pinch value of the fingers to detect if they are grabbing.
The implementation details of this pinch calculation are more low-level than Unity and are thus encapsulated below the managed-native boundary. This type merely provides an API surface through which to invoke the native functionality.
