MouseState.ScrollWheelValue Property

  • 项目

Note

This property is available only when developing for Windows.

Gets the cumulative mouse scroll wheel value since the game was started.

Namespace: Microsoft.Xna.Framework.Input
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

Syntax

public int ScrollWheelValue { get; }

Property Value

The scroll wheel value.

Remarks

Unlike standard Windows and WinForms mouse messages, which report a relative value for the scroll wheel, XNA reports the total scroll wheel value accumulated over the length of a game's execution. To process a wheel movement, you must compare the previous frame's wheel value to the current wheel value.
