But how to use /u2b07

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>

Purpose of Font class / how to print non-bold text online

What exactly is actually the purpose of the Greenfoot.Font class? You can’t actually format a text so that it prints with it, so what should it be used for?

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

Snake Game Add Tail Question

Last reply by danpost, over 5 years ago:

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.

Can you give me some more codes please? Btw, thanks for helping.

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).

How to remove/add an actor from a different world

I never got the addObject to work it always gave either the "cannot find symbol - variable ..." error or if I put .class after the actor, the "java.lang... cannot be converted to greenfoot actor.

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.

I thought the world a=inkomthi, would make count for inkomthi

Creating a game but counter keeps breaking

I changed the ifs so they were the same and their hitbox appears to be smaller. But the worlds do not save when I go in between them does this have something to do with Greenfoot.setWorld(new Outside());?

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.

Scenario not working on Greenfoot site

By mrjswaine, with 2 replies.
Last reply by RcCookie, over 5 years ago:

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.
