How can i get my game to stop when the class has been eaten or the player has completed the game??? (This is prbably easy to you guys...)

The first part is easy .. after all of a class has been eaten. In your world class act method add the single line

if (getObjects(ClassName.class).isEmpty())
{
    Greenfoot.stop();
    return;
}

The second part would use the same block code (lines 2 through 5 above); but the code would probably be in the class of the player and the condition would be different.

I put this in my background part then line 2 to 5 in my wombat, but when i had "eaten" the objects it still caried on... im slightly confused, it also did it when the wombat got "eaten". programming for the wombat...

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

/**
 * Write a description of class snowman here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class Wombat extends Animal
{
   public void act()
   {
   move();
   checkKeypress();
   
       if (canSee(Leaf.class))
       {
           eat(Leaf.class);
       }
                    
       if (canSee(Ant.class))
       {
           eat(Ant.class);
       }
   }
   
   public void eat()
   {
       Actor Ant;
       Ant = getOneObjectAtOffset(0, 0, Ant.class);
       if (Ant != null)
       {
           World world;
           world = getWorld();
           world.removeObject(Ant);
           Greenfoot.playSound("slurp.wav");
       }
       
       {  
        Greenfoot.stop();  
        return;  
       }
   } 
    
   public void lookForAnt()
   {
       if (canSee(Ant.class))
       {
           eat(Ant.class);
           Greenfoot.playSound("slurp.wav");
       }
            
       if (canSee(Leaf.class))
       {
            eat(Leaf.class);
            Greenfoot.playSound("slurp.wav");
       }
   }
        
   public void checkKeypress()
   {
        if(Greenfoot.isKeyDown("left"))
        {
            turn(-4);
        }
            
        if(Greenfoot.isKeyDown("right"))
        {
            turn(4);
        }
        
    }

@11frendash: Inside the class or method you want to run when the programme should end. Enter the code described below.

//Do something like this...
public GameOver(int score) {
Greenfoot.stop();
        GreenfootImage text = new GreenfootImage("Game Over\nCoins: " + score, 40, Color.RED, new Color(0, 0, 0, 0));
        GreenfootImage image = new GreenfootImage(text.getWidth() + 20, text.getHeight() + 20);
        image.setColor(new Color(255, 255, 255, 128));
        image.fill();
        image.drawImage(text, 10, 10);
        setImage(image);
        Home home = new Home();
        Greenfoot.setWorld(home);
    }

Just remove lines 39 through 42 of the Wombat class above and put the code I gave above in your world act method replacing 'ClassName' with 'Ant' or 'Leaf', which ever needs to be entirely eaten to win. If both then replace the first line with

if (getObjects(Ant.class).isEmpty() && getObjects(Leaf.class).isEmpty())

The compiler will not be able to find the Color class unless you add the following import line:

import java.awt.Color;
