I'm a beginner coder so I'm extremely sorry if this is a rookie mistake! I need to hand this in in like 3 days so it would be extremely helpful if anyone can help me! My code looks like this : super(500, 350, 1); start2 secondstart2 = new start2(); addObject(secondstart2,318,395); player1 player1 = new player1(); addObject(player1,165,152); player2 player2 = new player2(); addObject(player2,454,149); langa langa = new langa(); addObject(langa,84,273); langb6 langb6 = new langb6(); addObject(langb6,454,149); langb56 langb56 = new langb56(); addObject(langb56,454,149); langb5 langb5 = new langb5(); addObject(player1,454,149); } } however, none of the objects would show up on my scenario. Another problem : This is the code for my background (world scenario) also, I have a start button for my scenario, which starts like this : if (Greenfoot.mouseClicked(start)); getWorld().setBackground(new GreenfootImage("background2.png")); However, as soon as I click run on the greenfoot scenario, the scenario changes to background2.png without the start button being clicked and the start button just stays on the second page; not disappearing while the other buttons won't show up. please help! thank you!

I think it would help more if you just posted the entire class codes instead of snippets from them. Also, please use the 'code' link below the reply box for inserting code into you posts.

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

/**
 * Write a description of class background2 here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class background2 extends World
{

    /**
     * Constructor for objects of class background2.
     * 
     */
    public background2()
    {    
        // Create a new world with 600x400 cells with a cell size of 1x1 pixels.
    
        super(500, 350, 1); 
        start2 secondstart2 = new start2();
        addObject(secondstart2,318,395);
       
        player1 player1 = new player1();
        addObject(player1,165,152); 
        
        player2 player2 = new player2();
        addObject(player2,454,149); 
        
        langa langa = new langa();
        addObject(langa,84,273); 
        
        langb6 langb6 = new langb6();
        addObject(langb6,454,149); 
        
        langb56 langb56 = new langb56();
        addObject(langb56,454,149); 
        
        langb5 langb5 = new langb5();
        addObject(player1,454,149);  
    }
}
second code : 
     public void act()
    
    {
       if (Greenfoot.mouseClicked(start)); 
       getWorld().setBackground(new GreenfootImage("background2.png"));
    }
}

Again, I cannot tell where this act method is with it by itself like that. I will say this much, however. It appears you are trying to create and start a new world by changing the background image of the first world. If you are, it is not done that way. It would still be the first world with a different background image; and, the constructor of the second world would never be executed. You need to use 'new background2()' to create a 'background2' world. You can create and set one active using 'Greenfoot.setWorld(new background2());'.
