I want to learn physics modeling from the lunarDrifter scenario. Greenfoot is working on my PC, but I don't see a way to expose the java code for lunarDrifter. What I expected to find is a way to download the scenario (like I can in Scratch). Perhaps re-using someone's code isn't encouraged or facilitated in Greenfoot? Any solutions?

PS, this should be catagorized "Other" I'm sure -- apologies.
