I'm trying to make a game where when you touch the block, your character disappears, but at the last "Person" it says "cannot find symbol- variable

import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

/**
 * An obstical in this game
 * 
 *  
 * 0.0.1-1.10.2017
 */
public class Block extends Actor
{
    //Act command
    public void act() 
    {

    }    
    //Used for aranging the blocks
    public void turn()
    {
        turn(90);
    }
    //For losing the game
    public void eat()
    {
        if (isTouching(Person.class))
        {
            World world;
            world = getWorld();
            world:removeObject([u]Person[/u]);
        }
    }
}

Just replace lines 26 - 28 with

removeTouching(Person.class);

It's saying that there is no variable person, and I agree, I don't see a variable named Person anywhere in the class,. In fact as a side point I don't see any variables defined in this class at all.

You have no code in your act method. You need to call your methods from there:

public void act()
{
    turn();
    eat();
}

You don't call the 'eat' method from anywhere. You could put the following in line 14:

eat();

This will work then, but it would probably be more clever to put the code into the Person class and check for touching the block instead of doing it the other way around as you did. I mean if you have your hand on a stone (in real life), would you say that you are touching the stone or that the stone is touching you?
