Hi everybody, I am a teacher and want to use Greenfoot to teach Java to beginners. In order to make coding accessible to my pupils I would like to have all Actors offer a method called setX() and setY() instead of setLocation(). I changed the Actor.java within \Greenfoot\lib\english\greenfoot\api\greenfoot but it won't show in the Greenfoot-Project-Window when right-clicking an added object. How can I make changes to the superclass Actor? To be clear: I do not want setX() to show in the BlueJ-IDE / Subclass - but I want to be able to use the method as an inherited method. Thanks a lot. Best regards Christoph
