Sets the rolloff factor, which determines the rate of attenuation over distance.
object.SetRolloffFactor( _ rolloffFactor As Single, _ applyFlag As CONST_DS3DAPPLYFLAGS)
If the method fails, an error is raised and Err.Number may be set to DSERR_INVALIDPARAM.
The rolloff factor has a range of DS3D_MINROLLOFFFACTOR (no rolloff) to DS3D_MAXROLLOFFFACTOR (defined as 10 times the rolloff found in the real world). The default value is DS3D_DEFAULTROLLOFFFACTOR (1.0).
