IDirectSound3DListener::SetPosition

The IDirectSound3DListener::SetPosition method sets the listener's current position, in distance units. By default, these units are meters, but this can be changed by calling the IDirectSound3DListener::SetDistanceFactor method.

HRESULT SetPosition(
  D3DVALUE x,    
  D3DVALUE y,    
  D3DVALUE z,    
  DWORD dwApply  
);
 

Parameters

x, y, and z

Values whose types are D3DVALUE and that represent the coordinates of the listener's new position vector.

dwApply

Value indicating when the setting should be applied. This value must be one of the following:

DS3D_DEFERRED	Settings are not applied until the application calls the IDirectSound3DListener::CommitDeferredSettings method. This allows the application to change several settings and generate a single recalculation.
DS3D_IMMEDIATE	Settings are applied immediately, causing the system to recalculate the 3-D coordinates for all 3-D sound buffers.

Return Values

If the method succeeds, the return value is DS_OK.

If the method fails, the return value may be DSERR_INVALIDPARAM.
