Needing help with the subject above i have tried this code: public void youWin() { if (score==5) { getWorld().addObject(new YouWin(), 400,300); Greenfoot.stop(); } } Had no errors while testing and couldnt get it to work. If you're needing any other code to see what the problem could be just ask thanks.

Make an actor subclass, called Score, that has a private int variable called 'score'. Add any methods that you want to use when adding to your score. Create a getter method for 'score' (possibly called getScore()) . In your World act method, reference and check your score by saying: 
Score s = (Score)getObjects(Score.class).get(0);
if (s.getScore() == 5){
   addObject(new YouWin(), 400, 300);
   Greenfoot.stop();
}

Yes, if the counter subclass does the above.

How do you create a getter method?

A getter is used to retrieve a value. In this case, to make a getter, create a method that has return type 'int' named 'getScore'. In the function, just return the score variable. It should look like this: 
public int getScore(){
   return score;
}

Wait, don't put that in your world, put that in your counter class.

Just to review: In your Counter class: // initialize a variable named 'score' // create a getter method like the one mentioned above In your world class: // reference and check the score like mentioned above

import greenfoot.*;  

public class Counter extends Actor
{
    int score = 0;
    
    public void act() 
    {
        setImage(new GreenfootImage("Score : " + score, 24, Color .BLACK, Color.GREEN));
    }    
    
    public void addScore()
    {
      score++;
    }
    
}
