public int pointerId;

Description

Identification of the pointer.

When using a mouse the pointerId returns -1, -2, or -3. These are the left, right and center mouse buttons respectively. When using touchscreen on mobile versions (such as iPad, iPhone, or Android), touches go from 0 up to however many touches the device supports.
