Microsoft DirectX 8.0 (C++)

IDirectSound3DListener8::SetPosition

Sets the listener's position, in distance units. By default, these units are meters, but this can be changed by calling the IDirectSound3DListener8::SetDistanceFactor method.

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

Parameters

x, y, and z
Values that specify the coordinates of the listener's position vector. Note that DirectSound may adjust these values to prevent floating-point overflow.
dwApply
Value that specifies 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 IDirectSound3DListener8::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.

Requirements

  Header: Declared in dsound.h.
