Okay -- Super_Hippo hit it precisely. The reason that they do not reset is because the fields are static. I doubt that any of the fields need to be static. I get the feeling that some of them do not need to be fields at all (but, would have to see the rest of the class and understand what 'd', 'j' and 'k' refer to). Is there any reason that you made the fields 'static' to begin with?

How do you change the background of world in the code. THe user picks the size of the grid 10 by 10 ect how do i make it so that if for instance the variable that causes the grid to be a 9 by 9 is called what would i put in this if statment.

if(variable){
change image from this to that

}

i have tried

if(Grid==8){
                            setImage ("Greenfoot Background.png");
            
        }

but it cannot find method setImage. this is in my game world

The method for setting a background to a World is 'setBackground...' instead of 'setImage...' which is for Actors.

I have a problem. Look at the photo below its is my options. for some reason after i click run and then reset it and chose a different option it does not change it. code is below plz help.

code for page of image and buttons button by 8 by 8 9 by 9 and 10 by 10 are the same but with corrosponding number e.g 8 by 8 = 8 9 by 9 = 9

import greenfoot.*;


public class Layout1 extends Actor
{
    public void act() 
    {
       GreenfootImage image = getImage();  
        image.scale(40, 40);       
        setImage(image);
        if (Greenfoot.mouseClicked(this)) {
            Game.Grid=8;
    }    
}}

next is the code for my run button

  Greenfoot.setWorld(new Game());
            if(Game.Grid==8){
               Game.x=500;
                Game.y=500;
            }
            if(Game.Grid==9){
                Game.x=550;
                Game.y=550;
            }
            if(Game.Grid==10){

                Game.x=600;
                Game.y=600;
            }

finally here is the code for my world game

 public static int y=500;


    /**
     * Constructor for objects of class Game.
     * 
     */
    public Game()
    {    

        super(x, y, 1); 
        if(Grid==8){
            setBackground ("Greenfoot Background.png");

        }
        if(Grid==9){

            System.out.println(x+""+y);
            setBackground ("Backnine.png");

        }
        if(Grid==10){

            setBackground ("Backten.png");

        }

any help would be appreciated i do not know why when i reset it sometimes it doesn't change the image or the size of world.

In your run button ('Play' button) code, how about setting the 'x' and 'y' before creating and setting a new Game world active.

        super(x, y, 1);

in the game world(when i tried putting anything but that first i got a error message)
