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++;
    }
    
}

Add the getter method in the Counter class.

Yes, it's fine. Now, in the world class, do the following: Counter s = (Counter)getObjects(Counter.class).get(0); if (s.getScore() == 5){ addObject(new YouWin(), 400, 300); Greenfoot.stop(); }

        addObject(new Food(),400,100);

        addObject(new Food(),700,100);
       
    }

    public void SharkEnters()
    {
        if( Greenfoot.getRandomNumber(100)<1)
        {
            addObject(new Shark(),25,300);
        }

    }
    
    public Counter getCounter()
    {
        return counter;
    }

    
}

and here's my world class

First, remove the getCounter method. Second, add an act method and put the code I mentioned above in it.

That works thanks so much for your help

You could just use this as your Counter class. Then you only change the image when needed and only check for score=5 when it is needed (=when it changed):

import greenfoot.*;  
 
public class Counter extends Actor
{
    private int score = 0;
     
    public Counter() 
    {
        updateImage();
    }    
     
    public void addScore()
    {
        score++;
        updateImage();
        if (score == 5)
        {
            getWorld().addObject(new YouWin(), getWorld().getWidth()/2, getWorld().getHeight()/2);
            Greenfoot.stop();
        }
    }
     
    private void updateImage()
    {
        setImage(new GreenfootImage("Score : " + score, 24, Color.BLACK, Color.GREEN));
    }
}
