Gets a cue-instance variable value based on its friendly name.

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

Syntax

public float GetVariable (
         string name
)

Parameters

name
Friendly name of the variable.

Return Value

Value of the variable.

Remarks

Cue-instance variables are useful when multiple instantiations of a single cue (and its associated sounds) are required (for example, a "car" cue where there may be more than one car at any given time). While a global variable allows multiple audio elements to be controlled in unison, a cue instance variable grants discrete control of each instance of a cue, even for each copy of the same cue.

Exceptions

Exception type	Condition
ArgumentNullException	The name parameter is null.

Platforms

Xbox 360, Windows XP SP2, Windows Vista
