DirectSound3DBuffer.SetVelocity

The DirectSound3DBuffer.SetVelocity method sets the sound buffer'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 DirectSound3DBuffer object.

x, y, and z

Values that represent the coordinates of the 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

Velocity is used for Doppler effects only. It does not move the buffer.

The default unit of measurement is meters per second, but you can change this by using the DirectSound3DListener.SetDistanceFactor method.
