Hello, I am trying to make a game over screen appear when the player dies. The code compiles and runs however, the .setBackground() method isn't actually changing the background. The removeObjects method isn't working either. Here's the code I have written: 
    public void act() 
    {

        int xpos = getX() - 5;
        if (xpos <= 0) 
        {
            getWorld().removeObject(this);
        }
        else 
        {
            setLocation(xpos, getY());
            Actor player = getOneObjectAtOffset(0,0,RocketPlayer.class);
            if (player != null)
            {
              
                getWorld().removeObjects(getWorld().getObjects(Actor.class));
                getWorld().setBackground(new GreenfootImage("gameOver.jpg"));
                 slow();
                 Greenfoot.setWorld(new MainMenu());
            }
        }

    }

What does the 'slow' method do?

Slow is a method I created that uses Thread.sleep() Hers the code for that method: 
    public static void slow()
    {
        try
        {
            Thread.sleep(5000);
        }
        catch (Exception e)
        {
        }
    }

Okay, that does not allow the background to be repainted before the MainMenu world becomes active. Try this instead: 
public void slow()
{
    int n = 250;
    while (--n > 0) Greenfoot.delay(1);
}

You can probably drop the 'slow' method altogether and replace line 18 above with this: 
Greenfoot.delay(250);
