This game illustrates 1) how to create a new world that already has objects 2) how to use a for loop 3) how to accept keyboard input to move an actor around

You may want to consider making the world a bit smaller - it doesn't fit on my laptop's screen all at once, which does make running it / moving around more difficult!

mjrb-4, thank you for your suggestion. I can make it smaller. Can you tell me what size would fit on a laptop?

That's an interesting point actually - for me it's around 1000x450 but, as they say, milage may vary. If you have a look on greenfoot discuss I've started a thread about what sizes fit what people... hopefully people will reply which may give you a better idea! Also, note the sizes I've used there are in pixels, not in 2 pixel blocks like you've used here (which will invariably make it twice as big!) - was there a reason behind using a cell size of two pixels? Usually when you want the smoothest movement, the 1 pixel size is best.

mjrb4, Thank you. I changed the screen to 600, 400, 1. The 2 was an accident. I'm glad you pointed that out. I'll sign up for Greenfoot discuss.

by the way, when you unzip this scenario, it's called obiwanfightsanakin, because the eventual goal is to turn this into a game where Obi-Wan Kenobi fights Anakin (Star Wars)
