I've been working on a day/night cycle when I started this game but now I want to add different backgrounds, the Idea is to make my game look like the player is traveling around the world, the world only has two images it uses to change backgrounds or in other words two functions for the day and night time, well now i want to add a third background to change the image from the night time image to the next day time image. The idea is to switch background images in order. my issues is that when i do the cycling, two of the images are stuck together, these are night() and day2(), here's the coding for the timing of each image

 public boolean isDay()
    {
        return (time/10000)%2==0;
    }

and here's the if statements of switching the images

  if ( isDay() )
        { 
            day();
        }
        else if (isDay()) 
        {
            night();
        }
        else
        {
            day2();
        }

help plz

So you want to have the images day (for day 1), night (for night 1) and day2 (for day 2)? Is day3=day1, day4=day2 then and so on? Right now, line 1 and line 5 has the exact same condition, so either it is day (line 1 is true) and line 5 isn't executed or it is not day and both are condition are not met.

exactly. Day= day1 night = night1 day 2 = day2 night 2= night2 day 3 =day3

when it turns into night time, or night(), both night() and day() are happening at the same time, i need it to where i can add infinite amount of images and put them where they can go in the order i put them in

Maybe something like this would work:

private int time = 0;

private int currentImage = 0;

private GreenfootImage[] images =
{
    new GreenfootImage("day1.png");
    new GreenfootImage("night1.png");
    new GreenfootImage("day2.png");
    new GreenfootImage("night2.png");
    new GreenfootImage("day3.png");
    new GreenfootImage("night3.png");
    //....
};

public MyWorld()
{
    super(.....);
    setBackground(images[0]);
    //...
}

public void act()
{
    if (++time % 20000 == 0)
    {
        currentImage++;
        setBackground(images[currentImage]);
    }
}

will it loop after it gets to the last image?

oh wait, im sorry. i misspoke the function, the day and night aren just images, but they're also their own functions, the day and night cycle each have their own functions like location of actors, here's the coding of the day and night cycle

 public void night()

    {
        setBackground("roadBack7.png");
       
        if (time % 10 == 1 )
        {
            addObject(new Tree2(),Greenfoot.getRandomNumber(15)+474,0);
        }
        if (time % 10 == 1 )
        {
            addObject(new Tree2(),Greenfoot.getRandomNumber(5)+132,0);
        }
        if (time % 15 == 1 )
        {
            addObject(new House2(),Greenfoot.getRandomNumber(5)+30,0);
        }
        if (time % 20 == 1 )
        {
            addObject(new Stick2(),111, 0);
        }
       
    }  

    public void day()
    {
        setBackground("roadBack.png");
        
      
        if (time % 10 == 1 )
        {
            addObject(new Tree(),Greenfoot.getRandomNumber(15)+474,0);
        }
        if (time % 10 == 1 )
        {
            addObject(new Tree(),Greenfoot.getRandomNumber(5)+132,0);
        }
        if (time % 15 == 1 )
        {
            addObject(new House(),Greenfoot.getRandomNumber(5)+30,0);
        }
        if (time % 20 == 1 )
        {
            addObject(new Stick(),111, 0);
        }
        
    }    
    public void day2()
    {
        setBackground("roadBack3.png");
        
      
        if (time % 10 == 1 )
        {
            addObject(new Tree(),Greenfoot.getRandomNumber(15)+474,0);
        }
        if (time % 10 == 1 )
        {
            addObject(new Tree(),Greenfoot.getRandomNumber(5)+132,0);
        }
       
        
        
    }
