Microsoft DirectX 8.1 (Visual Basic) |
The SetVelocity method sets the listener's velocity.
Syntax
object.SetVelocity( _
x As Single, _
y As Single, _
z As Single, _
applyFlag As CONST_DS3DAPPLYFLAGS)
Parts
object
Resolves to a DirectSound3DListener8 object.
x, y, z
Values that specify the coordinates of the listener's velocity vector. DirectSound may adjust these values to prevent floating-point overflow.
applyFlag
Value that specifies when the setting should be applied. 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 DirectSound3DListener8.SetPosition method.
