As u said that ' if any user misuses it, then the user will be barred from use ' Does it need programming (i think its not possible but sometimes u make it possible) or to inform the developers of greenfoot

Programming -- yes. I will add to a list of banned users and update the scenario. Only need to check the name of the user against the list.

do i put this in the lines that you mentioned earlier?

That would be for step (3); however, you will need to do step (1), which assigns the intersecting platform to the variable ground, for it (step 3) to work. The other steps would still need to be completed, as well, for the behavior to be righted.

When I published my game to the Greenfoot website, it showed a Java.lang runtime error.

I think it has to do with your static final bgImage field. Something about static or static final object references being assigned an object right off doesn't seem to go well with HTML5 javascript.

Thank you so much, I did not know that thanks for the help.

How to access Variables from touching subclass?

That fixed it! It now works perfectly. Thank you for your help danpost. Appreciate it.

The reason why the "double" word needed to be removed is that with it, you are defining a NEW local variable with the same name as the pre-defined field; without it, it will refer to that pre-defined field. Line 5 can also be written as: <Code Omitted>

Say you have a class Player. This class should extend SmoothMover, a Greenfoot class that uses floating-point variables to store the actors position. You can import it by right-clicking onto the panel with „Actor“ in Greenfoot and selecting „Import“.

Although, I am not sure about the instructions given to import it. I know of using the menu bar with :

Making actors stay on top of each other (overlay)

Adding looks okay. Do you have an act method in your NodeRB class (if not, a class it extends)? Show, if so.

I realized my mistake. Since i was updating the locations of all objects in my WorldScrolling method I didn't have to update my text location in my NodeRB also, since it was already added in the world over it. Thank you for your feedback though !

How to edit new subclass template

By Quabey, with no replies.

Hello, today I was wondering how to change the template when you create a new subclass. I found the post from Super_Hippo (https://www.greenfoot.org/topics/58272/0), but it seems outdated. So here's an update on how it works, because I think I'm not the only one who annoyed by the explanation you have to delete every time you create a new subclass. If you want to edit you need to go to C:\Program Files\Greenfoot\lib\english\greenfoot\templates there you will find the actorJava file in which you can edit the template for new subclasses. In the same folder is also the worldJava file which can be edited to change the MyWorld template. I personally removed the Act explanation and the import greenfoot.*; comment. It now looks much cleaner. I hope I could help someone.

Unfortunately, your suggestion didn't bring anything. He still turns left instead of right on the left side. Still, many thanks to you.

You need to move line 3 up outside the act method (line 0 or -1). You have it where it is always a new var assigned with "links". It ?may? also be required that it should be assigned "rechts", instead.
