How do I gather all objects of a actor class in a variable?

For what purpose? What are you going to do with the list? I suspect you will iterate through the list either to do something with all the actors or with specific types within the list, in which case: <Code Omitted>

tell me what is the real size of my scenario Is it size or size on disk

Image and sound files are usually what makes up the majority of the size of large scenarios. The number of classes and number of dependencies between them can influence load time; but, again, image and sound files are a much greater influence.

I hear you. The reason i ask is because i am a school teacher and on of my students told me about this problem and when i looked at it i found out that most of the time it's ok and only sometimes this problem appeared in the game and i didn't know how to explain it (i still don't) because i'm not java expert. Anyway thanks

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?
