source: code/trunk/src/orxonox/objects/WorldEntity.cc @ 1569

Last change on this file since 1569 was 1559, checked in by landauf, 17 years ago

used isInitialized() in destructors where needed and changed constructors back to normal variable initialization instead of the "myclass() : variable(value), …" pattern. in my opinion this is much more comfortable and I hope everyone agrees ;)
