Counter Trouble

how i made the counter?
erdelf, i reviewed the video "Joy of code number 27, and realized i just forgot to add something to the world's code.
i have just updated the game with the counter.
I was just wondering....... the code you added---- (space.finished() ) would i be able to delay that until the man eats a certain number of burgers?
can u put an example of how i would write that?
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
import java.awt.Color;
/**
* Write a description of class person here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class person extends Actor
{
private Counter counter;
public person(Counter count)
{
counter = count;
}
/**
* Act - do whatever the person wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
if(!space.getEnd())
{
if (Greenfoot.isKeyDown("right"))
{
turn (2);
}
if (Greenfoot.isKeyDown("left"))
{
turn (-2);
}
if (Greenfoot.isKeyDown("up"))
{
move (2);
}
if (Greenfoot.isKeyDown("down"))
{
move (-75);
}
Actor burger;
burger = getOneObjectAtOffset(0, 0, burger.class);
if (burger != null)
{
World world;
world = getWorld();
world.removeObject(burger);
Counter cp = (Counter) (getWorld().getObjects(Counter.class).get(0));
if(cp.getScore() > 2 /* x 2 */) // replace this
{
setImage(new GreenfootImage("YOU WIN",180, Color.WHITE, Color.YELLOW));
space.finished();
}
cp.addScore();
setLocation(290, 200);
}
createNewBurger();
}
{
private void createNewBurger()
{
burger newburger;
newburger = new burger();
World world
world = getWorld();
int x = Greenfoot.getRandomNumber(600);
int y = Greenfoot.getRandomNumber(480);
world.addObject(newburger, x, y);
}
}
}
}
please disregard the previous post...... i have a new error
at greenfoot.core.Simulation.runContent(Simulation.java:210) at greenfoot.core.Simulation.run(Simulation.java:203) java.lang.IllegalStateException: Actor not in world.

please help me with this..... im done editing the last few things i need to add to the game and this just keeps popping up every time i try to compile...
In the code you provided, you have the wrong bracket at line 64, and if my count is right, 2 extra brackets at the end.
The new error is in the alligator class, in its constructor. You are probably using either 'getX' / 'getY', or one of the 'getObjects' commands, which will not work in the constructor.
