What do the Bullet and Psuedocode classes look like??

Okay -- no conflicting code there. Is there any code elsewhere that deals with the score or health?

No -- nothing there that would cause the behavior you suggest.

That would allow a more complete inspection. Make sure you check the 'Publish source code" checkbox in the dialog box.

Try this

import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

/**
 */
public class Counter  extends be
{
    private int totalCount = 0;

    public Counter()
    {
        setImage(new GreenfootImage("Score shown here", 30, Color.ORANGE, Color.BLACK));
    }

    /**
     * Increase the total amount displayed on the counter, by a given amount.
     */
    public void bumpCount(int amount)
    {
        totalCount += amount;
        setImage(new GreenfootImage("" + totalCount, 30, Color.ORANGE, Color.BLACK));
    }
}

For the health bar:

import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

/**
 * Write a description of class Level_4 here.
 * 
 * @author (your name) 
 * @version (a version number or a date)

public class HealthBar extends chaar
{
    int health = 4;
    int healthBarWidth = 300;
    int healthBarHeight = 30;
    int pixelsPerHealthPoint = (int)healthBarWidth/health;
    /**
     * Act - do whatever the Level_4 wants to do. This method is called whenever
     * the 'Act' or 'Run' button gets pressed in the environment.
     */
    public HealthBar()
    {
        update();
    }    

    public void act() 
    {
        update();
    }

    public void update()
    {
        setImage(new GreenfootImage(healthBarWidth + 2, healthBarHeight + 2));
        GreenfootImage myImage = getImage();
        myImage.setColor(Color.WHITE);
        myImage.drawRect(0, 0, healthBarWidth + 1, healthBarHeight + 1);
        myImage.setColor(Color.BLUE);
        myImage.fillRect(1, 1, health*pixelsPerHealthPoint, healthBarHeight);
    }

    public void loseHealth()
    {
        health--;
    }    
}

If you don't want to have a health bar but thats what I have in my game. It does the same thing

For the losing of the health:

Actor (Actorname) = getOneIntersectingObject((actorname).class);
        if((Actorname) != null)
        {
            World myWorld = getWorld();
            (Worldname) (worldname) = (Worldname)myWorld;
            HealthBar healthbar = (worldname).getHealthBar();
            if(touching(actorname) == false)
            {
                healthbar.loseHealth();
                touching(actorname) = true;
                if(healthbar.health <=0)
                {
                    myWorld.removeObject(this);
                }    
            }    

        } else { 
            touching(actorname) = false;
        }

Change all the (actornames) in to the actor which will deal damage. And change (worldname) into your worldname and (worldname) into a short form for the world name instead of writing the entire world name again. For example. If your world name was Water and your actor which was dealing the damage was called Jeremy then this would be the code:

Actor Jeremy = getOneIntersectingObject(Jeremy.class);
        if(Jeremy != null)
        {
            World myWorld = getWorld();
            Water water = (Water)myWorld;
            HealthBar healthbar = water.getHealthBar();
            if(touchingJeremy == false)
            {
                healthbar.loseHealth();
                touchingJeremy = true;
                if(healthbar.health <=0)
                {
                    myWorld.removeObject(this);
                }    
            }    

        } else { 
            touchingJeremy = false;
        }

put this in the void act for the actor which is losing health.

Also add this code to the world class.

HealthBar healthbar = new HealthBar();

and

    public HealthBar getHealthBar()
    {
        return healthbar;
    }
