So in my game when the world starts it plays music, but when the world ends it doesn't stop playing music, help please!

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

/**
 * Write a description of class Space here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class Space extends World
{
//private Score score;

    /**
     * Constructor for objects of Space
     * 
     */


    public Space()
    {    
        // Create a new world with 20x20 cells with a cell size of 10x10 pixels.
        super(850, 550, 1,false);
        addObject(new Aligator(),0,250);
        addObject(new Camel(),625,283);
        //addObject(new Score(),50,50);
        int count =0;
                
          {  
                Greenfoot.playSound("Sound.wav");
            }
            
        while(count<=30)
            {
                addObject(new Frog(),Greenfoot.getRandomNumber(800), Greenfoot.getRandomNumber(500));
               count = count+1;
               
            }
        }
        
     
   // public void addPoints()
    //{
        //score.addPoints();
   // }
   // public void addLittlePoints()
   // {
     //  score.addLittlePoints();
   // }
   // public void subtractPoints()
   //{
      //  score.subtractPoints();
   // }
}

if you create an object from type GreenfootSound you can start and stop it's playing.

huh?

first thing you do is define the sound as a variable:

private GreenfootSound bgSound;

then define location:

bgSound = new GreenfootSound("background.mp3");

I created two methods the first to have sound start:

    public void started()
    {
        bgSound.playLoop();
    }

the second to stop the sound when the game is over:

  public void gameOver()
    {
        bgSound.stop();
     }

hope that helps :)

woops I read my file wrong. I do hve an Act method. The act method I have to check if the health bar goes to 0. If it does then read the gameover function. but the start of your world class should be:

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

/**
 * Write a description of class Space here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class Space extends World
{
    private GreenfootSound bgSound;

    public Space()
    {    
        super(850, 550, 1,false);
        addObject(new Aligator(),0,250);
        addObject(new Camel(),625,283);
        bgSound = new GreenfootSound("Light.mp3");
        int count =0;
        while(count<=30)
        {
            addObject(new Frog(),Greenfoot.getRandomNumber(800), Greenfoot.getRandomNumber(500));
            count = count+1;
        }
    }

    public void act(){ //need some function to check for gameover
        if (bar.value == 0){
            gameOver();
        }
    }

    public void started()
    {
        bgSound.playLoop();
    }

    public void gameOver()
    {
        bgSound.stop();
    }

}

I do not have a health bar though? The only way the world ends is it the camel touches the Alligator.

#

so the function which checks for collision between camel and alligator should be in the Act method

I'm sorry but I'm confused.
