DirectSound3DBuffer.GetVelocity

The DirectSound3DBuffer.GetVelocity method retrieves the current velocity for this sound buffer.

object.GetVelocity(velocity As D3DVECTOR)

Parameters

object
Object expression that resolves to a DirectSound3DBuffer object.
velocity
D3DVECTOR type that receives the sound buffer's current velocity.

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. For additional information, see Doppler Factor.

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