Microsoft DirectX 8.1 (C++)

IDirectSound3DBuffer8::SetMinDistance

The SetMinDistance method sets the minimum distance value.

Syntax

HRESULT SetMinDistance(
  D3DVALUE flMinDistance, 
  DWORD dwApply 
);

Parameters

flMinDistance

New minimum distance value. D3DVALUE is defined as float in D3dtypes.h.

dwApply

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

Value Description
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.

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 meters per unit).

Requirements

  Header: Declared in dsound.h.
