What is the error that Greenfoot gives you? That might give some clue as to why you can't use that method
If I scroll the world, the Object moves to the left uppon corner...
And that's just, if the Method is called "move"...
As of Greenfoot 2.1, Actors have a move(int) method. So your actor inherits this from the Actor class. This leads to your actor having two move methods:
move (int) -- inherited from Actor
move (double) -- in your own class
So far, there's nothing wrong with this. This is not a problem.
Now: How are you calling your move method? If, for example, you call it like this:
move(4);
then the move(int) method will be invoked, because your actual parameter (4) is an int. Java checks for the best match in parameter lists.
If you rename you method, it all works, because Java will recognise that there is an int parameter, and the only matching method expects a double, and then convert your int to a double. But if there's a method where the int fits without conversion, it'll call that one.
So, in short: to ensure that your own method is called, use a double as an argument:
move (4.0);
That should do it.
