What are the goals for each level? Level 1 is 50. Level 2 = 70. Level 3 = ? etc?

Are there any other changes between the levels? For examples, (1) are there more grid-squares? (2) are there more enemies of any kind? (3) does the Wombat gain or lose any characteristics or abilities? Is the game supposed to stop after the third level?

I believe you will have the same problem(s). It would just be a bit more complicated in the world class.

i thought that if i had the method that changed the world in each world that when it switched world that the old value would not work, and if i put that reference to the counter in each world that it would use the value set for the corrent world

If there are no other changes other than the number of leaves to be eaten, then you only need one world (there is no sense in duplicating worlds just to change one int variable). A whole new sub-world is not warranted for such a change. Replace the code I gave you before with the following

// class fields
static int level = 0; // to track the level
static int[] goal = { 50, 80, 100 }; // to specify goal at each level
// in the act after 'eatLeaves'
if (leavesEaten == goal[level])
{
    level = level + 1;
    if (level == goal.length) // are all levels complete
    {
        Greenfoot.stop();
        return;
    }
    else
    {
        Greenfoot.setWorld(new MainWorld());
        return;
    }
}

if (Wombat.level == 0)
{
    // add whatever
}
else if (Wombat.level == 1)
{
    // add whatever
}
else if (Wombat.level == 2)
{
    // add whatever
}
in the world constructor or a method it calls to add what is needed for each level.

i have a way i just need a way to get a refference to the amount of the counter

i have an idea is there a way to transfer the wombat to the next level without resetting the leavesEaten counter

int counterValue = ((Counter) getObjects(Counter.class).get(0)).getValue(); This will work as long as there is a counter in the world. Check to make sure getObjects(Counter.class) is not empty before using this statement if there is any chance a counter is not in the world.

To transfer the Wombat object to the next world, your constructor will need to accept a Wombat type object within a parameter.

public World2(Wombat wombat)
{
    super(12, 12, 50); // or whatever size
    addObject(wombat, x, y); // replace x and y with values
    // add all the other objects
}

Actually, you can just make the leavesEaten field a 'static' field. That will preserve it between world changes and make it accessable with 'Wombat.leavesEaten' in any world or actor sub-class. Then, you can use (in the Wombat class after 'leavesEaten = leavesEaten + 1;'
?

if (leavesEaten == 50) Greenfoot.setWorld(new World2());
else if (leavesEaten == 130) Greenfoot.setWorld(new World3());
else if (leavesEaten == 230) Greenfoot.stop();
and not have to pass anything to any world. Also, it would not matter if you created a new Wombat object in each level, since any wombat object will increment the same 'leavesEaten' counter when a leaf is eaten.
