nevermind, I literally JUST figured it out haha!! but I do have another question of how to make the sound only play once when the spacebar is hit?

here is the code if you need it import greenfoot.*; public class Hero extends Actor { public void act() { checkKeys(); } public void checkKeys() { if (Greenfoot.isKeyDown("space")) Greenfoot.playSound("Boo.wav"); } }

I didn't attempt it yet but I was looking at the API page at it was like it'll play in a sequence (got confused)

You can probably get away with creating one instance of the sound (your current code will create multiple instances, one after another, for each act step that the space key is down):

import greenfoot.*; 

public class Hero extends Actor
{
    GreenfootSound booSound = new GreenfootSound("Boo.wav");
    
    public void act()
    {
        checkKeys();
    }    
    
    public void checkKeys()
    {
        if (Greenfoot.isKeyDown("space")) booSound.play();
    }
}

It will repeat if the space key is held down, but it will not play on top of itself.
