Class Finger

A source of touches (Touch).

Inheritance
object
Finger
Namespace: UnityEngine.InputSystem.EnhancedTouch
Assembly: Unity.InputSystem.dll
Syntax
public class Finger
Remarks

Each Touchscreen has a limited number of fingers it supports corresponding to the total number of concurrent touches supported by the screen. Unlike a Touch, a Finger will stay the same and valid for the lifetime of its Touchscreen.

Note that a Finger does not represent an actual physical finger in the world. That is, the same Finger instance might be used, for example, for a touch from the index finger at one point and then for a touch from the ring finger. Each Finger simply corresponds to the Nth touch on the given screen.

Properties

currentTouch

The currently ongoing touch for the finger or default(Touch) (with valid being false) if no touch is currently in progress on the finger.
