Hello, I need help with changing levels on my Greenfoot Game. The code works but it only changes one level and then stops working. Here is the code:

    int currentLevel = 1;

    public void changeLevel()
    {
        if (canSee(Emblem.class))
        {
            World thisLevel = getWorld();
            World newLevel = new Level1();
            if(currentLevel == 1)
            {
                newLevel = new Level1();
                currentLevel++;
            }
            if(currentLevel == 2)
            {
                newLevel = new Level2();
                currentLevel++;
            }
            if(currentLevel == 3)
            {
                newLevel = new Level3();
                currentLevel++;
            }
            Greenfoot.setWorld(newLevel);
        }
    }

You have an object in a world. You set "currentLevel" to 1. When it touches the "Emblem", it's "currentLevel" will be 2. Now a new world is set, a new (=another) object of this class is added to the world (I guess) and its "currentLevel" is set to 1. If your worlds are similar, then use one class for them. Then you can do something like this:

//Level class
private int currentLevel;

public Level(int level)
{
    super(….);
    currentLevel = level;
   //create Level based on the variable
}

public void nextLevel()
{
    Greenfoot.setWorld(new Level(currentLevel+1));
}

//class in which your code currently is, in act method
if (isTouching(Emblem.class))
{
    ((Level) getWorld()).nextLevel());
}
