Input.mouseScrollDelta

Switch to Manual
public static Vector2 mouseScrollDelta ;

Description

Текущее положение мыши в пиксельных координатах. (Read Only)

Input.mouseScrollDelta is stored in a Vector2.y property. (The Vector2.x value is ignored.) Input.mouseScrollDelta can be positive (up) or negative (down). The value is zero when the mouse scroll is not rotated. Note that a mouse with a center scroll wheel is typical on a PC. Modern macOS uses double finger movement up and down on the trackpad to emulate center scrolling. The value returned by mouseScrollDelta will need to be adjusted according to the scroll rate. In the example below a scale of 0.1f is used.

Note that mouseScrollDelta is read-only.
