How to use the Source on GitHub
This repository on GitHub contains an eclipse project that contains the source of GreenfootKara and all the scenarios. There is a source folder for the Kara classes and a source folder for the scenarios of each chapter.
To build all Greenfoot scenarios you should use the Ant build file (build.xml). This will ...
- ... create a target folder containing the scenarios (with and without solutions)
- ... create another folder containing zip files with scenarios zipped by chapter
