Omg, thanks so much, it finally works.

Best might be an int field that is set to the round number when showing the text (using the condition that it is not yet the current round number).

You could probably scroll one background image, as opposed to using the background gif images, to free up some memory.

Line 78 may also need adjusting. Try the following there: <Code Omitted>

So it actually said "true" but I noticed that I made a basic mistake in my structure, so I had to put the array in another class and now it works. But still thank you very much for your try to help me!!

Okay -- so line 25 creates a HIGHSCORE object and line 27 invokes the 'showHighscore' method on that object. However, the method cannot execute properly because it invokes the 'addObject' method on the value returned by calling 'getWorld'. But, 'getWorld' will return 'null' -- not any World object because the HIGHSCORE object is never added into any world. You cannot invoke any method on a 'null' reference.

The site name has been changed, you can now access it here.

The way the terminal works by me is the newest output gets added to the bottom, it doesn't push all the old stuff down and go to the top.

The code I gave you should be placed in the act method of the one which shoots the fireballs, so the mage. <Code Omitted> getX and getY takes the position of the mage which will then be used as coordinates for the fireball.

You cannot compare an image to a String (lines 26 and 45). Lines 34 through 37 should be in the act method of the Note class. Lines 26 through 31 should be removed and the following should be added after line 33: <Code Omitted>Lines 47, 48 and 50 can be removed; but I do not know what you can replace line 45 with. Lines 56, 57 and 60 can also be removed.

It is definitely your 'addShips' method that is troublesome. I would have used something more along this line:

Works like a miracle, thank you.

I wish my teacher had any knowledge about programing when he introduced GF to us... It looks like you know what you are doing and hopefully your students can follow your thoughts. Usually you will get an answer like "Greenfoot is not thread-safe" from the GF team. Since I am not really into this, I can't tell you what you can do against this... GF is for beginners and that's why it gives you an environment without the need of using complicated java things. When I tried porting GF scenarios to android using Droidfoot, I had to use eclipse and I didn't have a clue about anything. I probably wou

Thanks for the help danpost. It works and feels much better now :D.
