| Microsoft DirectX 8.1 (C++) |
The 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.
Syntax
HRESULT SetConeOrientation(
D3DVALUE x,
D3DVALUE y,
D3DVALUE z,
DWORD dwApply
);
Parameters
x, y, and z
Values that specify the coordinates of the sound cone orientation vector. 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.
Requirements
Header: Declared in dsound.h.
