IDirectSound3DBuffer::SetConeOrientation
The IDirectSound3DBuffer::SetConeOrientation method sets the orientation of the sound projection cone for this sound buffer. This method has no effect unless the cone angle and cone volume factor have also been set.
HRESULT SetConeOrientation(
D3DVALUE x,
D3DVALUE y,
D3DVALUE z,
DWORD dwApply
);
Parameters
x, y, and z
Values whose types are D3DVALUE and that represent the coordinates of the new sound cone orientation vector.
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.
