DirectSound3DListener.SetVelocity

The DirectSound3DListener.SetVelocity method sets the listener's velocity.

object.SetVelocity(x As Single, _
    y As Single, _
    z As Single, _
    applyFlag As CONST_DS3DAPPLYFLAGS)

Parameters

object

Object expression that resolves to a DirectSound3DListener object.

x, y, and z

Values that represent the coordinates of the listener's velocity vector. DirectSound may adjust these values to prevent floating-point overflow.

applyFlag

Value that indicates when the setting should be applied. This value must be one of the constants of the CONST_DS3DAPPLYFLAGS enumeration.

Error Codes

If the method fails, an error is raised and Err.Number may be set to DSERR_INVALIDPARAM.

Remarks

The default velocity is (0,0,0).

Velocity is used only for Doppler effects. It does not move the listener. To change the listener's position, use the DirectSound3DListener.SetPosition method.
