works perfectly, thank you very much!

As I thought im just Stupid lol. I had to call the remove method. works now, thanks.

No, because Button is not the interface with one method. But you could write <Code Omitted>

In class of actor: <Code Omitted>

<Code Omitted>and <Code Omitted>The iterators, i, remain at zero (no increments given). So, it is stuck in a loop. World object never completes initializing. In fact, Key objects are created for the first white key multiple times, repeatedly, until memory runs out, whereby you will get a OutOfMemoryException.

hi danpost finally got it working thanks for the help :)

Two ways to do that (at least). One is to create a world whose background mimics the real world, like in a paused state. It is not a world in a world, but it could be made to appear as such. Another way, which does not involve another world altogether, is to just use an actor for the "little screen". Just have all operations suspended while that actor is in the world. For further details, just ask.

Thank you! I’ll try it later.

Default key-binding is Ctrl+Space. You can change it in the settings.

yes i think i was a bit blind with my code ive just seen it, ill change it to more a appropriate wording , thank you :) ill come back if it still isnt working.

Scale down your images in the files themselves. Also, remove any excess transparencies around the outer edges (top, left, right and bottom) of the images.

The question is a little bit difficult to understand. So, I will give you answers to some questions and hope that one of them is helpful for you. 1. How to change the current(-ly shown) world (while the scenario is already running)? Call the method Greenfoot.setWorld with the new world as parameter, e.g. <Code Omitted> 2. How can I set a different world to be the start world (=the current world at the start of the scenario)? Right click on the World class that you want to be used for the start world (e.
