Thank you. You teach me one more way to write the code. I like this simplified way.

Do you call the movement method from the act method?

Not quite so "all-seeing". You have duplicate references of "normalWall2" and "normalWall3" as well -- and "normalWall4".

Scale all images in the addedToWorld method.

Actually, it should be a backslash, as "\u2b07" or "\u2193". Use in quotes as shown to include the represented character within a string. So: <Code Omitted>

Thanks!

Wow, thanks danpost! I have to complete this project for school tomorrow, so I was kinda worried you wouldn't respond. Thanks for saving my day!

The GreenfootImage class drawString method uses the set font to render its given text.

When you create a new LoseWorld object, you create a new Snake object. Of course its score is 0. The Snake object that creates the LoseWorld object contains the score. Just pass it to the LoseWorld constructor.

It might help if you go over what methods are available in the different classes provided by greenfoot. You can find them here. Start with the World and Actor classes (for now).

I saw you in a bunch of other posts and want to thank you so much for the speedy reply! I have a major progress check due tomorrow and you saved my life! Thank you so much Mr. Danpost! I can't imagine how many other people you helped save and hope this message goes to heart because I'll likely be needing your help some more sometime in the future.

So, either you had a faulty reference to an actor or a reference to something that was not an actor at all. A class of type Actor or sub-type of Actor is not an Actor instance.

Show your current Rocket class codes.

Correct. You will need to keep a valid reference to any world that you wish to return to if you want it to be exactly as you left it. You could adjust the score in the world proceeding to when changing worlds. Sidenote: I would not have thought the hit box size would be changed.

I lately had the same problem, and for me it was caused by running a later version of the jdk. It is fine in the application but the JavaScript conversion doesn’t seem to work. Try to reinstall Greenfoot, or download the zip and replace the jdk folder in your Greenfoot installation with the one from the zip. Finally, make sure to delete all the class files and use the recompile option from one of the drop down menus because sometimes Java ain’t recompile everything automatically and just show an error.
