IDirectSound3DBuffer8::SetConeOrientation

The SetConeOrientation method sets the orientation of the sound projection cone.

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

Parameters

x

Value that specifies the x coordinate of the sound cone orientation vector. D3DVALUE is defined as float.

y

Value that specifies the y coordinate of the sound cone orientation vector. D3DVALUE is defined as float.

z

Value that specifies the z coordinate of the sound cone orientation vector. D3DVALUE is defined as float.

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 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 3D coordinates for all 3D 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

This method has no effect unless the cone angle and cone outside volume have also been set to values other than the default.

Requirements

Header: Declared in Dsound.h.

Import Library: Use Dsound3d.dll.
