gulp thx i have a look

@nccb Again, this it great. I won't go back using my own ScoreBoard, this is much, much better. Check it out if you want, I already updated it.

cant bye oh well just gotta work it out myself!

Thank you very much!

danpost - that does work, although sometimes its just easier to close and reopen.

There are some extra parentheses in danpost's suggestion that you need to remove for it to compile: <Code Omitted>

The score updating for recency was actually bourne's idea that I implemented recently. The store() method seemed to be not storing properly during my initial testing, but it must have been a different problem in the code. Thanks for the clarification!

@rdlatimer I don't think you are right. When you press act, every object will run the action act(). When you press the run button, Greenfoot simply runs the act() action for every object in the world, the whole time. So actually, the run button in Greenfoot just runs a loop where every object will run the act() method. I hope this lets you understand Greenfoot al little better. (If you're wondering where I got this information: from the Greenfoot book)

Ok; you implement "scrolling" by moving everything to the left (or right). In Greenfoot this could be as simple as getting all the objects (World's getObjects() method) and then looping through them and adjusting their position. You should use an unbounded world so that objects can move out of the world bounds. It's a bit more complicated if you need the background to scroll as well, but to start with you could use a plain background to avoid that problem. This technique isn't particularly efficient, but

Math.hypot(x, y), thanks for sharing that! Yeah the abs() is redundant now that you mention it. And yeah I changed it to Actor instead of Object once I realized I need to call some methods within them. Thanks :D!

Great, thanks for the help, much appreciated.

Download and check out this side scroll demo. That should get you going.

No worries, I've finally figured it out :)

Hit the 'Compile' button. (Hint: whenever the classes have this stripey look, they need to be compiled.)

well i cant take credit for this. i did get these ideas from the book. but i understand now what to do. i think the major mistake that i was that i put the increment of a inside the if statement. my mind kind of went towards that but for some reason i didnt try it. thanks for the reply.
