In order to use FingerGestures features, there must be exactly one instance of the FingerGesture component in your scene. This component acts as a manager for the user input and is used by the various gesture recognizers and finger event detectors that we'll cover in the next sections of the manual.
To do so, simply drag the “FingerGestures” prefab from the Plugins\FingerGestures\Prefabs folder into your scene. Alternatively, you can also create an empty object and add the “FingerGestures” component to it.
Using the Make Persistent flag will allow the FingerGestures singleton object to persist across scene loads, so you only need to set it up once in your start scene.
