Microsoft DirectX 8.0 (C++)

IDirectSound3DBuffer8::SetMaxDistance

Sets the maximum distance value.

HRESULT SetMaxDistance(
  D3DVALUE flMaxDistance, 
  DWORD dwApply 
);

Parameters

flMaxDistance
New maximum distance value.
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.

Remarks

The default maximum distance, defined as DS3D_DEFAULTMAXDISTANCE, is effectively infinite.

Requirements

  Header: Declared in dsound.h.
