If you want to return false when the following is true (as well as the opposite, i.e. return true when is false) getObjectsInRange(200, Princess.class).isEmpty() Then return that with a "not" (!) at the front of it Like the following: return !getObjectsInRange(200, Princess.class).isEmpty();

Try typing 'fullscreen' in the search bar and looking at some of the scenarios and the discussions about it.

Thank you very much

No, as they aren't necessary for Greenfoot's purpose.

That would require a list of identifiers of those maps that you like. Each identifier would somehow have to uniquely correspond to a particular user and a particular map of that user. A question would be how many likes are each user allowed to give? Again it would consume the space available per UserInfo very quickly, decreasing amount dedicated to map data

You should be able to use 'counter.add(-counter.getValue();' or 'counter.setValue(0)'.

once again jones plz help

jonesy la help me please reply asap

Ah, I see. I think danpost is right. You seem to have confused Greenfoot, the application, with this website (which is the Greenfoot website). If you don't have Greenfoot installed, follow the Download link above and the instructions there. The instructions regarding opening scenarios are referring to the Greenfoot itself, not to the Greenfoot website.

Ok the support told me what to do I tell you here how to solve this problem easily. You go to you Greenfoot installation folder, then you open the folder lib, then you find the file bluej.defs and you open it with the notepad. Here you will have a line where it's written : #bluej.lookAndFeel=crossplatform You have to erase the # from this line and then save. If it doesn't want to save on this folder, save it to your destkop and then copy your file into the lib folder. Now it should work !

If you want to make a transparent rect that's easy. You just have to check where the rect should begin and where it ends and set the pixels at this points to transparency using the setColorAt method. If you want to use circles it's a bit more difficult. Unfortunately you can't just overdraw the image with a transparent color. You need to overdraw the image you want with a color you don't use in your whole image. Then if you have overdrawn the circle you want to 'delete' you need to use two for loops to check the rect where you circle is in. Every pixel that is in the color you used to overdr

Hey sorry but im not realy sure how i would begin or what coding i would use to make the maze game itself

Thanks davmac, I think that is exactly what I was looking for, I'll give it a go :)

*facepalm* Thank you! So... I just need to make sure to create the instance when an event happens, instead of when the world loads... wow I feel stupid. :/

I think the problem was that you used an 'int' variable for angle. That only gives you 6 possible directions (there are 2 x PI radians in a full circle, i.e. just over 6). Try:
