I'm basically new to Greenfoot, and I was looking to use tutorial with my students today, but there seems to be a problem with the Crabs Scenario. I downloaded zipped file, but I can't get the crab to move or turn. When I try to compile I get "cannot find symbol - method move (int)" or method turn. In a "little-crab" scenario downloaded to use with book, crab was extended from animal. Animal had method to move. In this tutorial, crab is extended from actor, and there doesn't seem to be any "move" or "turn" methods for actor. Do I have any idea what I'm talking about? Thanks.

We have made some changes to Greenfoot since the book's release, which is what you are running into. There's two versions of the crabs:
  • If you want to follow the book, you should download the book scenarios and use the little-crab scenario from the chapter02-04 directory. This will work with any version of Greenfoot.
  • If you want to follow the tutorial on the website, you should download the crab scenario linked at the top of tutorial 2. This requires you to have at least version 2.1.0 of Greenfoot.
I suspect the problem you are having is either that you have downloaded the book crab scenario and are attempting to follow the online tutorial -- or that you are attempting to follow the online tutorial with an older version of Greenfoot (2.0.x or earlier).
