Please show the entire 'ScoreLabel' class code. The amount of code given is not very helpful.

this is all i have in it currently i dont know what to really do with it...
/**
 * Write a description of class ScoreLabel here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class ScoreLabel extends Actor
{
    public ScoreLabel (String text)
    {
        GreenfootImage img = new GreenfootImage(text.length()*10, 30);
        img.setColor(java.awt.Color.white);
        img.drawString (text, 2, 15);
        setImage(img);
    }
   public void setText(String text)
   {
    GreenfootImage img = getImage();
    img.clear();
    img.drawString (text, 2, 15);
    }
}

OK, you will need to obtain or retain a reference to the ScoreLabel object created by this class in the class where the 'score' is located and accumulates in. Then, anytime the score changes, set the text of the ScoreLabel object to the new text showing the new score.

Whichever class (bullet or rock) that performs the collision detection. The ScoreLabel class does not need modified.

Before we can adjust the ScoreLabel image to display the new score, we need an 'int' field that keeps track of the score. Do you have one yet? and, if so, which class is it in (name the class and what class it extends, back to 'World' or 'Actor') and how is the field declared?

Please refer to the Java tutorials -- especially the trail on Learning the Java Language.
