Thank you very much, really helpful!!

Well, first you would need some indicator for when this condition should be checked. This could be a time limit or a limit on number of moves. It could be at a certain break point as like the end of a level or something else. Whatever this indicator is, when indicated, check the score and either allow the game to continue or not. To stop the game, usually all it takes is a "Game Over" text message (with possibly showing the score) and stopping the scenario (using "Greenfoot.stop();").

You cannot put "\" in a String without one of the characters on the bottom of this page following it.

One should not be impolite/ill-mannered/rude to someone, whether that someone is a beginner or not.

Try the 'Greenfoot.ask' method.

Add another condition along with the key detection for each direction. For example: <Code Omitted>

For a triangle 'nPoints' would be '3' and 'xPoints' and 'yPoints' would both be int arrays of length 3. Let us say you had an image of size 100x100. To draw a triangle that goes from bottom-left corner to bottom-right corner to top-left corner (back to bottom-left corner), then you have this:

Actually, it varies depending on the speed of your system. However, in general, at normal running speed, it is around 60 fps. Therefore, initializing your 'time' field to '600' would be about right. Sidenote: it is a bit strange to see a 'while' where an 'if' is sufficient. You could also code act method as follows:

thank you!!!!

Change line 10 to: <Code Omitted>

I agree that only one subclass for the arrows is the way to go. I also believe you should have actors for the pads (again, using only one subclass of Actor). The rotation of a pad can be given to any arrow that approaches it and the arrows can be placed into the world at the location of its pad and immediately moved to the other end of the alley so it can begin its approach.

This should work: <Code Omitted>

Instead of using 'clear' on the image, it might be better to set the image of the actor to 'null' <Code Omitted>It can then be easily checked as to whether it is showing or not: <Code Omitted>

Thanks man
