Parameters: key  is the key to check. release  if true, the pushed state of the key is released (force to be false). It will return to true next time only if key is released and then re-pushed.

Referenced by NL3D::CDriverUser::release, and NL3D::CEvent3dMouseListener::removeFromServer. void NLMISC::CEventListenerAsync::reset (    )    Clear all the Down states to false. Usefull sometimes when you don't bother what have been pushed before. e.g.: your app listen/test to the key 'A' and 'B' for a certain long period. Then, it test 'C' and 'D' later. If the user has press (by error) the key 'C' during the first period, this API has record it, and then, at the second period, isKeyDown(KeyC) will return true the first time the key is tested, unless if you do a reset() at the beggining of the second period. Clear all the pushed states to false too. See also: isKeyDown() Definition at line 195 of file event_listener.cpp. References _KeyArray, _KeyDownArray, and _KeyReleaseArray.
