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 I found the post from Super_Hippo (https://www.greenfoot.org/topics/58272/0), but it seems outdated.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.
