I want the game to end when the health counter <= 0 ive gotten this far so far but I don't know what to put into the if statement public void EndGame() { if ( totalHealthCount >= 0) { Greenfoot.stop(); Greenfoot.playSound("game-over.wav"); } } heres my health counter code;

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

/**
 * Write a description of class Counter here.
 * 
 * @author (ConorOwens) 
 * @version (20/02/13)
 */
public class HealthCounter  extends Actor
{
    private int totalHealthCount = 100;

    public HealthCounter()
    {
        setImage(new GreenfootImage("" + totalHealthCount, 60, Color.WHITE, Color.BLACK));
    }
    
    /**
     * Decrease the total amount displayed on the counter, by a given amount.
     */
    public void bumpHealthCount(int amount)
    {
        totalHealthCount += amount;
        setImage(new GreenfootImage("" + totalHealthCount, 60, Color.WHITE, Color.BLACK));
    }
}

Any help would be appreciated

first you should change the

Greenfoot.stop(); 
Greenfoot.playSound("game-over.wav");

around as you are stoping the game before it plays the sound also change >= to <= because you are checking to see if the health is above zero to end the game. so

 if ( totalHealthCount >= 0)

becomes

 if ( totalHealthCount <= 0)

ive done that but the game still continues on when health counter reaches 0 or below

Make sure that your 'bumpHealthCount' method is actually decreasing the value of the counter. If you are not supplying a negative number in the parameter, then you need to subtract the amount, not add it. @-nic-, I do not think it matters the order of the two statements. I believe the method will still finish after informing Greenfoot to stop the scenario.

yeah i have it adding -20 ....... do you have any idea why the game continues after 0 and below ? also the counter starts at 100 and then decreases every time an object hits the player

I dont think i explained what i need help with clearly, i need the game to end when the health counter is less than or equal to zero.

I am guessing that the 'EndGame' method is part of the HealthCounter class as well. Where is that method being called from (it should probably be called at line 26 in the code above). I eliminated the extra method and just put the code there, as it will only be called when the count is change anyway. The class should probably look like this:

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

/**
 * Write a description of class Counter here.
 * 
 * @author (ConorOwens) 
 * @version (20/02/13)
 */
public class HealthCounter extends Actor
{
    private int totalHealthCount = 100;

    public HealthCounter()
    {
        bumpHealthCount(100);
    }
    
    /**
     * Adjust the total amount displayed on the counter, by a given amount.
     */
    public void bumpHealthCount(int amount)
    {
        totalHealthCount += amount;
        setImage(new GreenfootImage("" + totalHealthCount, 60, Color.WHITE, Color.BLACK));
        if ( totalHealthCount <= 0)
        {
            Greenfoot.playSound("game-over.wav");
            Greenfoot.stop();
        }
    }
}
