I'm trying to make a new world when all the objects of a class are removed. I'm wondering if using the getOjbects class would work. Any suggestions?

I'm (pretty sure I'm) doing that, but I'm not sure how to get the values from the list (number of objects, etc.).

First, 'getObjects' is not a class, but a method. It is a member of the World class provided by greenfoot. If you look at the greenfoot.World class API documentation and check out the 'getObjects' method, you will find that it returns a List object. From there, you can check out the java.util.List class API documentation to see what methods are available for List object and what they do.

How do I make the list a variable? I have this written so far: 
public void isRemoved() {
        getObjects(Enemey.class);
        countObjects();
        if(list) {
            Greenfoot.playSound("upgrade.wav");
            Lvl2 lvl2 = new Lvl2();
            Greenfoot.setWorld(lvl2);
        }
    }
I just put something random in the if statement.
