He guys,
I have a question about how to learn more about programming in greenfoot.
I have finish the book from greenfoot.
Have someone an idea how I can learn more.
Is there maby a second book ?
It was not really my question:p
The name of the book is: Introduction to Programming with Greenfoot; writer = Michael Kölling
And yes it is worth to read it. You will learn the basic skills with this book
You could check out the Java tutorials (or Trails). The second section on the left, labelled in red, Trails Covering the Basics, would be the place to start, but there is much more you can learn through the other trails.
You could go on the videos posted by Micheal Kolling, called 'The Joy of Code' at http://blogs.kent.ac.uk/mik/category/joy-of-code/page/2/
although I think that they mainly follow the course of the book.
