IDirectSound3DBuffer::SetMinDistance
The IDirectSound3DBuffer::SetMinDistance method sets the current minimum distance value.
HRESULT SetMinDistance(
D3DVALUE flMinDistance,
DWORD dwApply
);
Parameters
flMinDistance
New minimum distance value.
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.
Remarks
By default, the minimum distance value is DS3D_DEFAULTMINDISTANCE, currently defined as 1.0 (corresponding to 1.0 meter at the default distance factor of 1.0 m per unit).
