What calls the World Constuctor when when the game starts in greenfoot? I want to add two worlds side by side, one a "Store" and one the "BalloonWorld", but how do I construct the "Store" world, with the "BalloonWorld" at the same time?

World(s) Constructor(s)
Only one of the world will be constructed when you compile or reset your project. You can make one load first by default by manually creating a world of that type (right clicking on the world icon and selecting 'new WorldName()'. You can, from any world, create an instance of a different world, or even of the same world, by coding 'new WorldName()'. Once that is done, you may or may not set that new world active:
You could create the store while constructing your BalloonWorld and save it in a field to use and re-use later.
When exiting the store use 'Greenfoot.setWorld(world);'..
World w = new Store(); Greenfoot.setWorld(w);
// instance field in BalloonWorld class
Store store;
// in the BalloonWorld constructor
store = new Store(this);
// instance field in the Store class
World world;
// begin the Store constructor with
public Store(World w)
{
// super constructor call -- 'super(int, int, int);'
world = w;
// rest of constructor
