There is an option called save the world if you right click on the background.

Thanks for the advice. I had the same problem and I believe it is resolved now after doing the Save The World before changing the code.

That means that you have not set a Counter object to the 'scoreCounter' class field.

Does any one know how this works?

Here is what I see: we have an Actor class that creates Rat objects (line 9) that initially moves 1 pixel per act (line 11). The fact that the 'speed' field has 'private' access and that the value of the field is never changed indicates that this initial speed is also its permanent speed when moving. This makes the 'for' loop in the 'act' method (line 18) unnecessary. The following should be sufficient: <Code Omitted>Now, for the 'move' method: lines 22 through 26 gets user keyboard input for movement of the actor by way of the arrow keys -- no problem

I'm not sure it needs updating. The window you posted shows that it doesn't specifically recognize Windows 7, but that it uses the "default windows plug-in" which I think should be ok. The real error is after that: "Failed to acquire device". To be honest I'm not sure what that means precisely; perhaps some other program that is running has already claimed the gamepad?

Thanks for the reply davmac :) As for other programs claiming the gamepad, I'm not sure about that, I'm not playing any other games with the gamepad plugged in at the time... There may be some hidden prog

Saving an integer

It would help if you show what you have tried (use the 'code' link below the reply box for posting code). The code for the pieces might be important; how many pieces created (or moving) might help; any extra information regarding what you are trying to accomplish (in general) might also help.

If you want to keep score during the game, I have made a downloadable ScoreBoard class that you might find useful. You can find the class here: http://mrstewartslessons.com/useful_class_scoreboard.html Simply download the class into your Greenfoot project folder. Close Greenfoot and open it again and you'll see the ScoreBoard class among your actors.
