Is there a scenario online, as example?

Thanks, will give your suggestions a try.

thanks everybody! i have got it right..

Create seperate actor classes for each part. Add to each one an instance List<Actor> array to hold the appendages (the parts that do not have further appendages do not need the list). Create the appendages for each part in the constructor of the class which that part extends from and add them to its list. Add an 'addedToWorld(World world)' method to add the listed objects into the world and call a method that you will add to each one (those with lists) called something like 'fixAppendages'. These methods will locate to listed appendages to there proper location dependent on its location. S

If you want the height for an Actor use the getImage() method i.e. <Code Omitted> The GreenfootImage class contains the getHeight method that returns the Height of an image. I am guessing you want the height of an Actors image. Check out the greenfoot docs for GreenfootImage.

usually when I ask a question I try not to ask for the straight question and if I do I ask what each part of the code does.

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
