Hey. I wrote the code seen below: 
import greenfoot.*;
import java.awt.Color;
public class Score extends Actor
{
    public int score;
    public Score() 
    {
        setImage(new GreenfootImage("Score: "+score,18,Color.BLACK,Color.GREEN));
    }
    public void addScore(int pn)
    {
        pn = pn;
        score = score + pn;
    }
    public int getScore()
    {
        return score;
    }
    public void update()
    {
        setImage(new GreenfootImage("Score: "+score,18,Color.BLACK,Color.GREEN));
    }
}
And the methods I use to create a class that did not see the new value. Why is this?

Maybe you have to add the method update in the method addScore: 
    public void addScore(int pn)
    {
        pn = pn;
        score = score + pn;
        update();
    }

Thank you for your attention. But I still have the same problem. During the study does not show the new value. 
import greenfoot.*;
import java.awt.Color;
public class Add extends Actor
{
    public Add()
    {
        setImage(new GreenfootImage("Press Space",18,Color.BLACK,Color.GREEN));
    }
    public void act() 
    {
        Score s = new Score();
        if(Greenfoot.isKeyDown("space"))
        {
            s.addScore(1);
        }
    }    
}
This is the code I tried to do the update.

You do not need another class (the 'Add' class in this case) to update the 'Score' class. Remove the 'Add' class and change the 'Score' class to the following: 
import greenfoot.*;
import java.awt.Color;

public class Score extends Actor
{
    public int score;

    public Score() 
    {
        update();
    }

    public void addScore(int pn)
    {
        score = score + pn;
        update();
    }

    public int getScore()
    {
        return score;
    }

    public void update()
    {
        setImage(new GreenfootImage("Score: "+score, 18, Color.BLACK, Color.GREEN));
    }
}
