if(getX() >= 3 && getX() <=5 && getY() ==3)    
{    
     //whatever code you choose    
     Greenfoot.stop();    
}

@DarrenM2012, what is the cell-size of your world (the third parameter in the 'super(int, int, int)' statement in your world class?

OK, that means if either of the two win location is occupied, then display the 'You Win' text object. MatheMagician had assumed that you cell-size was not pixel-sized, but you had not informed us of that fact until I had asked. You, obviously, cannot go with the idea of placing the transparent 'You Win' covering the exits. We are left with brute detection (which is not so bad, in this case): 
if (getX() == winX1 && getY() == winY1 || getX() == winX2 && getX() == winY2) 
{
    // insert code to execute when game is over here
}

Yeah, I assumed since you only had the mummies in your other discussion page cover three cells, it would be pretty ridiculous to have a mummy cover just three pixels of space.

I'm having trouble trying to get the world to display text as suggested by MatheMagician. In the character class I have: 
      if(getX() == 17 && getY()==15)  
    {  
         getWorld()).board(); 
         Greenfoot.stop();  
    }  
    else if(getX() == 18 && getY()==15)  
    {  
          getWorld()).board(); 
          Greenfoot.stop();  
    }
in the world subclass I have 
import java.awt.Color;  
import java.awt.Font;  
      
      
    public static final float FONT_SIZE = 48.0f;  
    public void board()  
    {  
             Font font = getBackground().getFont();  
             font = font.deriveFont(FONT_SIZE);  
             getBackground().setFont(font);  
             getBackground().setColor(Color.red);  
             getBackground().drawText("You win!",getWidth()/2,getHeight()/2);  
      
    }
The following line has an error when compiling 
    public static final float FONT_SIZE = 48.0f;

Sorry, could you post your entire world's code and I will fix it. I think I know what went wrong (and it was my fault).

Yes thanks that's all fine. now there's an issue with the get world and board thing within the character, sorry I only really know the basics.

You appear to have miscopied my code: It is supposed to say: 
if(getX() == 17 && getY()==15)    
{    
     ((background)getWorld()).board();   
     Greenfoot.stop();    
}    
else if(getX() == 18 && getY()==15)    
{    
      ((background)getWorld()).board();   
      Greenfoot.stop();    
}
You said: 
if(getX() == 17 && getY()==15)    
{    
     getWorld()).board();   
     Greenfoot.stop();    
}    
else if(getX() == 18 && getY()==15)    
{    
      getWorld()).board();   
      Greenfoot.stop();    
}

Sorry to be a annoying, but whilst compiling an error occurred within the background world subclass regarding .draw text.
cannot find symbol - method drawText.

I believe the correct method name is 'drawString'.
