So I was just reading through the code so I could understand what was going on and now no world is seen and when I tried to share it Greenfoot told me that no world class could be found.
The code of the world() class is:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Desert here.
*
* @author (your name)
* @version (a version number or a date)
*/

{
// instance variables
private int counter = 0;
private int spawnRate;
private int spawnY;
private int vehicleSpeed;
private int lives = 3;
private int level;
private int autoCount;
private Level currentLevel;
private boolean levelLoaded = false;
private boolean spawning;
private boolean actionPaused = false;
private boolean showScore = false;
private boolean deathSequenceActive = false;
// Not implemented yet:

private int chanceOfTriple;
// Sounds and Graphics loading
private GreenfootImage frogImage = new GreenfootImage ("frog.png");
private GreenfootImage splat = new GreenfootImage ("splat.png");
private GreenfootImage rivalImage = new GreenfootImage ("rival.gif");
// For some reason sounds work better if initialized in the constructor
private GreenfootSound smush;
private GreenfootSound levelUpSound;
private GreenfootSound gameOverSound;
// owned instance objects
private LifeCounter lifeCounter = new LifeCounter ();
private LevelCounter levelCounter = new LevelCounter ();
private Frogger myFrog = new Frogger();
private Rival redRival = new Rival();
//heart object
private Actor heart;
/**

*/
public Road()
{
// Create a new world with 600x400 cells with a cell size of 1x1 pixels.
super(600, 400, 1);
// Ensure that Frogs and Blood occur over top of everything else
setPaintOrder(Frogger.class, BloodPool.class, ScoreBoard.class, Enemy.class);
// Add the life counter to the World

heart=new Heart(); //create a new heart
addObject(heart,Greenfoot.getRandomNumber(451)+50,Greenfoot.getRandomNumber(226)+150); //add the heart to the world with random coordinates between (50,150) and (450,225)
//note: increasing the 300 in the if statement will create less hearts, and vice versa for decreasing

}
/**

private void spawnCars()
{
int randVal = Greenfoot.getRandomNumber(3)+1;

/**

The only other thing I did was create an Actor. In case it is the problem, the code for the new Actor is:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

* the 'Act' or 'Run' button gets pressed in the environment.
*/
private int speed;
private boolean active;
public Rival()
{
active= true;
speed=2;
}
public void act()
{
if (checkWin() )
{
endGame(true);
}
else if(checkDeath() && active == true)
{
active = false;
endGame(false);
}
}
public void addedToWorld (World w)
{
active = true;
}
public void advance()
{
if (active == true)
{
setLocation(getWorld().getWidth()-Greenfoot.getRandomNumber(100), getY());
move(4);
if (Greenfoot.getRandomNumber(150) < 10)
{
turn(Greenfoot.getRandomNumber(90) - 45);
}
if (getX() >= getWorld().getWidth())
turn(180);
}
}
private boolean checkDeath()
{
Enemy e = (Enemy)getOneIntersectingObject(Enemy.class);
if (e != null)
// if an enemy is detected colliding with Frogger, then death = true :(
return true;
return false;
}
private boolean checkWin()
{
if (getY() <= 32)
{
active = false;
return true;
}
else
return false;
}
private void endGame (boolean win)
{
// Return a message declaring win or lose to the Road (World)
Road d = (Road)getWorld();
d.endLevel (win);
}
public void setSpeed (int speed)
{
this.speed = speed;
}
}
