thanks a bunch

That's pretty cool. Thanks!

Thank you so much! Worked beautifully. P.S. Super appreciative for all the help you've given me and everyone else on this site

Okay -- your lists will never contain the same things. The reason being is that you create and add items to one list (in the PackingList class), then, you acquire the other list by using 'getIntersectingObjects' (in the Mannequin class). These lists may contain similar type items, but they will not be the same items (a Tank actor in one list is not the same Tank actor in the other list). Probably best is to create one of each item to start with. Save a reference to each and add a getter method for each. Then the world can get and add each into itself and the PackingList class can add thei

You cannot change a hard-coded value (which you currently are using for the speed of the sheep). The value for the speed (currently '2' everywhere for the sheep) needs to be replaced by a variable (a value that can be changed). That variable needs to be maintained by using a field. You will also need a timer field to track the time remaining that the sheep is to run at slow speed.

Let your world control that through its act method. If you mean create another actor and add it into the world -- no problem: <Code Omitted>It is possible to track whi

You would replace 'Color.LIGHT_GRAY' with 'new Color(0, 0, 0, 0)'.

Make use of the API documentation.

There is no way to make the current version of Greenfoot run with Java 9. The current development version of Greenfoot isn't publicly available and isn't in a usable state. However, the page you link to has a workaround that sounds like it should work with Java 8: Greenfoot runs as two separate JVM instances, and to add that parameter to the correct one you need to identify which instance the err

Thank you I appreciate that, didn't know about the sound folder!

The class java.util.Vector is not a (double rotation, double magnitude) type vector class. If you look at the documentation of the class, it extends the java.util.AbstractList class and creates an object that that is a collection (meaning elements -- objects -- can be added to it to create that collection. It has nothing to do with direction and force.

I have resolved the issue. I'll post the code just in case anyone needs this later. My world:

If anyone else using a Mac has this problem, the fix is to open your Terminal and type: defaults write -g ApplePressAndHoldEnabled -bool false For some reason it is not an option in System Preferences .

The greenfoot.Greenfoot class has the methods you will need both for checking on click on an actor and for changing worlds. Check out the documentation on the class.
