Thank you for your help, but sadly I have lost my game. I believe what happened is it updated to a new version and the code isn't compatible, though i dont think that would happen, I cant access any of the code at all and the images wouldn't show up for a while. but all this dosn't matter as I have moved on in my course and I am no longer using Greenfoot. I might come back later, but as for now I have nothing to do with Greenfoot anymore. again I thank you for your help.

Update to maps helper class?

By SliderG, with no replies.

In the "maps" helper class, there is a class that creates a Greenfoot image out of a Google map. It's throwing an error because it's can't find the file. It may be that the Google Maps API has changed its URL since this Greenfoot class was put together. The code contains the following line: private final String urlBase = "http://maps.googleapis.com/maps/api/staticmap?sensor=false"; I looked on the Google Maps API documentation to try to figure out what to replace this with, but no success so far. Any ideas how to bring this up to date?

I am not sure what this code does

Last reply by ChafikAZ, almost 5 years ago:

Even I could never had said it better, to sum it all up, it's incrementing it by one every time the code (presumably an if loop) is run through.

Sorry, I meant: how do I add different labels to them? There's only one counter class so I'm not sure how to do that.

Add a String parameter to Counter class constructor.
