how do you add music in the background while the scenario is running? i've tried the method Greenfoot.playSound("Spring.wav") because I want to play that song but a terminal window keeps popping up and says "could not open sound file". How can I fix this problem? thanks!

It could be the case that you haven't got this soundfile in your sound folder. If you have got it you could try to convert it into mp3. This doesn't work always but most times.

thanks! i've got it but another problem has occurred. I want the music to start when the scenario starts, but now it starts when I open greenfoot. How can I make the music start only when I press 'run' and end when I press 'stop'?

Create methods in your world subclass called "public void started" and "public void stopped". When you click run, whatever is in "started" will run once, and when you click stop, whatever is in "stopped" will run once.

It doesn't work. But I'm not sure if i am doing it correctly. here's my code: import greenfoot.*; // imports Actor, World, Greenfoot, GreenfootImage import java.util.Random; import java.awt.Color; public class CrabWorld extends World { // public static final Color pathColor = new Color(227, 202, 148); /** * Create the crab world (the beach). Our world has a size * of 560x560 cells, where every cell is just 1 pixel. */ public CrabWorld() { super(560, 560, 1); Greenfoot.playSound("Spring.mp3"); populateWorld(); prepare(); getWidth(); getHeight(); } /** * Create the objects for the start of the game. */ public void populateWorld() { } /** * Prepare the world for the start of the program. That is: create the initial * objects and add them to the world. */ private void prepare() { Counter counter = new Counter(); addObject(counter, 63, 28); Worm worm = new Worm(); addObject(worm, 452, 393); Crab crab = new Crab(counter); addObject(crab, 346, 415); Crab crab2 = new Crab(counter); addObject(crab2, 365, 186); Crab crab3 = new Crab(counter); addObject(crab3, 132, 198); crab2.setLocation(271, 186); removeObject(crab2); crab3.setLocation(500,400); addObject(new Crab(counter), 118, 254); addObject(new Crab(counter), 300, 300); addObject(new Lobster(), 390, 200); addObject(new Worm(), 200, 500); addObject(new Worm(), 30, 200); addObject(new Worm(), 60, 90); addObject(new Worm(), 80, 310); addObject(new Worm(), 150, 50); addObject(new Worm(), 290, 410); addObject(new Worm(), 220, 520); addObject(new Worm(), 380, 330); addObject(new Worm(), 410, 270); addObject(new Worm(), 130, 430); Worm worm12 = new Worm(); addObject(worm12, 394, 496); Worm worm13 = new Worm(); addObject(worm13, 319, 145); Worm worm14 = new Worm(); addObject(worm14, 513, 254); Worm worm15 = new Worm(); addObject(worm15, 179, 301); crab.setLocation(199, 415); } public void started (){ } public void stopped (){ } }

Remove Greenfoot.playSound("Spring.mp3").

private GreenfootSound bgMusic = new GreenfootSound("Spring.mp3");

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

    public void stopped()
    {
        bgMusic.stop();
    }
