You must realize by now that all non-static methods must be executed on an object (or instance) of the class. The getScore method of the UserInfo class is executed on a UserInfo object. The getMyInfo method (a static method executed on the class itself) may return a UserInfo object that the method can be executed on. Again, you still need to check to make sure null is not returned before attempting to execute the method on what is returned.

What version of Greenfoot are you running?

Thanks :)

All recent versions of Greenfoot include the JDK and don't require a separate download. Which version of Greenfoot have you installed? And when you say you have "reinstalled Java SE download several times" what download is that exactly (is it the JDK? If you're not sure, what was the URL of the web page you downloaded it from? What version of Java was it?)

A field is a variable that is declared within a class, but outside of any code blocks. A variable declared within a code block only exists during the execution of the block. Once an execution block terminates, variables declared within the block no longer exist. Example 1:

We've now replicated such an issue and fixed the bug ready for 3.5.1. Try the following to see if it also fixes the issue for you -- open your world class editor, then go to the very end of the class, and press return a couple of times to add a blank line at the end. The bug we found seemed to relate to the lack of a newline at the end of the file confusing the editor.

Hi, (as per Greenroom discussion) the student can contact support via support@greenfoot.org - if we have their email address/username we can investigate. The most likely reason is that they are entering the wrong username when logging in. (Perhaps they are entering their email address instead of username).

Thank you for this I found out that Greenfoot 3 requires JavaFX support, which is not available on the Raspberry Pi. Please use Greenfoot 2.4.2a. So anyone else having this problem with a raspberry pi just down grade. I found this out on the support page but decided to put it here to make one less click for everyone else.

Add the following line at the end of the addedToWorld method: <Code Omitted>

cool thanks

You do not have to change the method at all. Any actor passed to it, whether of Ogre type or not will be initially placed at a random edge point. You will need to call this method from where you remove an ogre from the world (when one is killed): <Code Omitted>

I used google translate to get this so I don't know if it's what you want exactly. But if you're wanting to delete objects you can use this. <Code Omitted>

Thanks :)

Swap lines 24 and 25 in the Bread class.
