I figured it out < Code Omitted > I had to change the "0 < amount" to "i < amount" simpler mistake

Simple, yet easy to miss (as apparent I had done). Sorry. Glad you found it.

changing worlds only when one box is pressed

It might help if you pass the focus-able text objects to the MenuSelector object and put the key control in its class. Then, have the world test a 'selected' field, which is set to the focused text (or its index) when "enterr" is pressed, to proceed to the appropriate world.

First, unless there is a visual need to have the generator as an Actor object, it should not extend the Actor class. Second, better is to use int fields to track number of each type bullets and create each as needed, rather than creating a number of them for later use.

Actually, the binary equivalent to 0.4 above was incorrect; but, my point still holds. The correct binary value should be 0.0110... with the fractional part repeating.

Counters not working

By Kordus, with 5 replies.
Last reply by danpost, almost 9 years ago:

'Counter' is a class name -- it does not refer to a particular Counter object. You need a reference to the particular Counter object whose value needs adjusting there. Insufficient code given to help in this respect.

I think the easiest way is to set it by the actor that creates it: <Code Omitted>

Help with one.setLocation(one.getX()+x2,one.getY()+y2); and List<Statment> everyone = getWorld().getObjects(Statment.class);

If this deals with scrolling, maybe this will be answered by the scrolling tutorial linked to your other discussion thread. (better to let the actor move and have the world adjust everything depending of what limitation you place on the actors location)

Does using inheritance slow down performance?

You will need to show what codes you are using to determine what the cause of your "unresponsiveness" is due to. It actually might be best to upload the project while making the source available so that iit can be properly diagnosed in a much more timely fashion.

I did the logic and im quite sure it works.

It should work with the current version of Greenfoot, provided you haven't called the World's setActorOrder(...) or setPaintOrder(...) methods. If you have used either of those methods (with an ordering), I think it won't work. (And as you've discussed already, it might not work in future Greenfoot versions).

Rotations from a point

Actually, I meant this: <Code Omitted>The documentation shows the constructor used to create an image of a specified size, plus the methods to get the width and height of an image and the method to draw an image onto another one. A cursory glance over the documentation would lead to most, if not all, of these. Like I said, my first post basically said it all, draw (line 3) the image (line 1) at (0, 0) (again, line 3) on
