Show class of that which creates a new EndScreenWorld object.

This is the class which creates EndScreenWorld. public class CatchWorld extends SimulationWorld { /* (World, Actor, GreenfootImage, Greenfoot and MouseInfo)*/ protected GreenfootSound music; protected double timeGameStart = System.currentTimeMillis(); public static double currentGameTime; /** * */ public CatchWorld() { super("", 800, 600, new Point2D(0.0, 0.0), 20); music = new GreenfootSound("gamePlay.wav"); setMusic(music); GreenfootImage background = getBackground(); background.setColor(Color.BLACK); background.fill(); prepare(); } /** * */ public void act() { super.act(); List<Bowl> bowls = getObjects(Bowl.class); if (bowls.size() > 0) { Bowl player = bowls.get(0); cameraCenter.setY(player.getPosition().getY() + 6.0); } currentGameTime = (System.currentTimeMillis() - timeGameStart) / 1000; if (System.currentTimeMillis() >= timeGameStart + 50000) { transitionToWorld( new EndScreenWorld(0)); } } /** * */ private void prepare() { Bowl bowl = new Bowl(); addObject(bowl, 400, 500); bowl.setLocation(400, 540); /* Generate apples for 20 screens*/ int i = 0; while (i < 12000) { int xPos = 40 + 60 * Greenfoot.getRandomNumber(10); /* get random number 1 or 2 for adding apples (appleCategory 1 for Green Apple, appleCategory 2 for Yellow Apple)*/ int appleCategory = Greenfoot.getRandomNumber(2) + 1; addObject( new Apple(appleCategory), xPos, - i); i = i + 60; } Score score = new Score(); addObject(score, 700, 56); } }

You need to get the score from the Score object.

No. You have to get the Score object from in the CatchWorld world and then get the score value from that Score object.

I added getScore at the bottom to get the score. Is this correct? public class CatchWorld extends SimulationWorld{ /* (World, Actor, GreenfootImage, Greenfoot and MouseInfo)*/ protected GreenfootSound music; protected double timeGameStart = System.currentTimeMillis(); public static double currentGameTime; private double score = 0; /** * */ public CatchWorld() { super("", 800, 600, new Point2D(0.0, 0.0), 20); music = new GreenfootSound("gamePlay.wav"); setMusic(music); GreenfootImage background = getBackground(); background.setColor(Color.BLACK); background.fill(); prepare(); } /** * */ public void act() { super.act(); List<Bowl> bowls = getObjects(Bowl.class); if (bowls.size() > 0) { Bowl player = bowls.get(0); cameraCenter.setY(player.getPosition().getY() + 6.0); } currentGameTime = (System.currentTimeMillis() - timeGameStart) / 1000; if (System.currentTimeMillis() >= timeGameStart + 15000) { transitionToWorld( new EndScreenWorld(0)); } } /** * */ private void prepare() { Bowl bowl = new Bowl(); addObject(bowl, 400, 500); bowl.setLocation(400, 540); /* Generate apples for 20 screens*/ int i = 0; while (i < 12000) { int xPos = 40 + 60 * Greenfoot.getRandomNumber(10); /* get random number 1 or 2 for adding apples (appleCategory 1 for Green Apple, appleCategory 2 for Yellow Apple)*/ int appleCategory = Greenfoot.getRandomNumber(2) + 1; addObject( new Apple(appleCategory), xPos, - i); i = i + 60; } Score score = new Score(); addObject(score, 700, 56); } /** * */ public double getScore() { return score; } }

No. From the world, you get a list of all Score objects: I put an explicit "this" in there to show you the structure of how to perform an operation on an object. The format is: << subject >> . << verb >> Because the code is in your CatchWorld class, any operation performed on "this" world can be coded without the subject being explicitly given. That is, the above line of code will work simply as: Now, with a list of score object being a List object, you can perform a get operation: The "Score" in parenthesis indicates that the object is indeed a Score object and can be assigned to a reference declared to be of type Score. Now, with the Score object, you can perform the getValue operation: All in all, this can summerized as: Then you can replace the "0" with "scoreValue".

Is there another method to display the score on endscreen? This method is a bit complicated and my teacher doesn’t expect this. I am given a scenario and I need to complete it without making too many changes

You could move the line: to outside the prepare method. Then simply use:
