- Description
The TDx_Sound3DListener::SetVelocity method will set the velocity for the listener.
This value is used to calculate doppler effects only, it is up to the application to move the buffer appropriately.
The default velocity is (0,0,0).
If the method call fails, the OnError event may be triggered with the following value:
DSERR_INVALIDPARAM
- Parameters
X
The X parameter defines a D3DVALUE representing the new X coordinate of the velocity vector.
Y
The Y parameter defines a D3DVALUE representing the new Y coordinate of the velocity vector.
Z
The Z parameter defines a D3DVALUE representing the new Z coordinate of the velocity vector.
Apply
The Apply parameter defines flags indicating whether the setting should be applied straight away.
The described effect applies when the flag is set.
-
DS3D_DEFERRED
Wait until the TDx_Sound3DListener::CommitDeferredSettings method is called before committing the settings.
This allows several changes to be made before recalculating.
DS3D_IMMEDIATE
Apply the settings immediately.
The 3D coordinates of all 3D sound buffers will be recalculated.
