IDirectSound3DBuffer8::SetPosition
Sets the sound buffer's position, in distance units. By default, distance units are meters, but the units can be changed by using 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 position vector. 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.
