I want to reference a setupLevel() method in my world Iron1. This is the code from my world IronManMode

            addObject( new PizzaCounter(), 725, 50);
        
        act();
        
    }
    public void act()
        {
        World IronManMode;
        
        
        List Sean = getObjects(Sean.class);
        List MenuButton = getObjects(MenuButton.class);
        if (Sean.isEmpty()  & MenuButton.isEmpty())
            {
            Greenfoot.setWorld(new Iron1());
            } 
           List Pizza = getObjects(Pizza.class);
        if (Pizza.isEmpty())
            {
            (IronManMode).setupLevel(0);
            }
        }
    }
I would like to setup a certain level in IronManMode from Iron1

# 
(IronManMode)getWorld().setupLevel(0);
Well, since I am never sure which ( ) are needed, it could also be one of the following... But test the first one first ;) 
(IronManMode)(getWorld()).setupLevel(0);
((IronManMode)(getWorld())).setupLevel(0);

neither worked I get an error that says that it can't find a method getWorld()

Oh sorry, I didn't see that Iron1 is a world class... Maybe this could work then: 
IronManMode newWorld = new IronManMode();
newWorld.setupLevel(0); //right now not needed if it is 0
Greenfoot.setWorld(newWorld);
You could also add a new constructor: (or just change it to it if your scenario does not start in the IronManMode class) 
public IronManMode(int level) //added parameter
{
    super(800, 600, 1); 
      
    setupLevel(level);
}
And then, you could use the following instead of the first code: 
IronManMode newWorld = new IronManMode(0);
Greenfoot.setWorld(newWorld);
