I think I got it. Hopefully I'll solve the rest of my project. Thanks for the great help.

I do not believe there is a command in the Greenfoot class that will stop the music. I do believe, however, that once the scenario is stopped, the music will stop after it finishes the current looping of it. If you wish to have more control of the music, use the GreenfootSound commands to start and stop the music.

Ah thank you very much! Its working nicely... I think my method had the right idea, but it was a little too complicated... and in the wrong class. Thank you!

Thanks :)

It appears that might be a bug that you will not be able to correct. After hitting reset, I noticed that the 'Pause' button was present (which means the scenario should be running); however, I was able to drag-n-drop the menu options in the scenario (and I am sure that is not programmed into your scenario). BTW, I was using a downloaded version of 'Platforms of meh' @Greenfoot team, could you look into this please and inform as to what the problem might be -- thanks.

It looks like "playbutton difficulty" is never actually set to anything, so it is null. <Code Omitted> I don't think you are coding this is the best way. You might want to try coding it in the following way: When a "star" is pressed, it gets "menu" and then passes the difficulty to it, which then stores it. Star will simply have a way to detect a mouse press, and then a method to pass difficulty information on to the menu.

I finally got Greenfoot to download and work. I think my issue is a bad version of Windows 8. I am hanging in Internet Explorer constantly and I cannot get Google Chrome to work either. I am very frustrated with Windows 8. thank you for your quick response.

No, the video tutorial is not the book, it uses different scenarios. In this case your link is to the teacher commentary which applies to the previous blog post, which also has a download link for the code: http://blogs.kent.ac.uk/mik/2012/01/joc-classes-and-objects/

Hi, have a look at the tutorials on the documentation page: http://www.greenfoot.org/doc

Sorry, I should of included that in my first post. The problem is with overriding. The GameOfLifeCell act() overrides the act() in Cell. It doesn't matter if the method is empty, it will still override it. You can see this overriding taking place as well with the applyRule() method.

@danpost, Not at all. I appreciate all the help I've had on here. Just don't think I have the gift of programming.

Thank you danpost! I thought I'd try my hand at creating it and was able to make one from following the instructions you posted. If you use the code I copied in my first post, it will end up ignoring the bordering cells. Fixing it so you don't ignore the bordering cells requires making sure it doesn't cause ArrayIndexOutOfBounds exception. This proves easy when altering the code I copied above a bit to use a 'for' loop for checking the locals.

Thanks!

Look closely at lines 190 and 191. Ask yourself, "What will be happening here?"; "Will this do what I need it to do?". By the way, 'removeObject' will not 'error' if the object is not in the world.
