В классе Block Нетбинс пишет ошибку "потеря this в конструкторе" на строках:
Листинг программы 
  1.  Game.platforms.add(this);
  2.         Game.gameRoot.getChildren().add(this);
А в классе LevelData пишет "использование статических неокончательных переменных при инициализации" Посоветуйте как сделать так чтоб заработало. Заранее спасибо всем кто откликнулся.
