Problem with Reseting the game

Farizio Farizio

#
I can't see anything which could create an error at this code, however if I reset the game it just crashes with no error log message or anything usefull for solving the problem. Codes in which the error could be: 
public class Background extends World
{
    private int imageCount = 0;
    private GreenfootImage bgImage = new GreenfootImage("Background.png");
    public int dif = MMPlayer.diff;
    public int height = 0;

    public void act() {
        imageCount += 4;
        drawBackgroundImage();
        height++;
        showText("Height:" + height + " / 3000",100,50);
        if(height >= 2980)
        {
            showText ("Level Completed",500,375);
            
        }
        switch (dif)
        {
            case 1:
            PlanetspawnerE();
            
            case 2:
            PlanetspawnerM();
            
            case 3:
            PlanetspawnerH();
        }
    }
... unnecessary

public class MMPlayer extends Actor
{
    public static int diff;
    public MMPlayer()
    {
        this.getImage().scale(50, 100);
        setLocation(500,700);
    }
    public void act() 
    {
        setImage("MMRocket.png");
        this.getImage().scale(50, 100);
        if(Greenfoot.isKeyDown("right"))
        {
            setImage("Rocket+30.png");
            this.getImage().scale(70, 82);
            move(4);
        }
        
        if(Greenfoot.isKeyDown("left"))
        {
            setImage("Rocket-30.png");
            this.getImage().scale(70, 82);
            move(-4);
        }
        
        if(Greenfoot.isKeyDown("up"))
        {
            setLocation(getX(), (getY()-4));
        }
        
        if(Greenfoot.isKeyDown("down"))
        {
            setLocation(getX(), (getY()+4));
        }
        
        Actor Easy = getOneIntersectingObject(MMEasy.class);
        Actor Medium = getOneIntersectingObject(MMMedium.class);
        Actor Hard = getOneIntersectingObject(MMHard.class);
        Actor Hitbox = getOneIntersectingObject(TryAgain.class);
        if(Easy !=null)
        {
            setImage("Explosion.png");
            diff = 1;
            Greenfoot.setWorld(new Background());
        }
        if(Medium !=null)
        {
            setImage("Explosion.png");
            diff = 2;
            Greenfoot.setWorld(new Background());
        }
        if(Hard !=null)
        {
            setImage("Explosion.png");
            diff = 3;
            Greenfoot.setWorld(new Background());
        }
        if (Hitbox != null)
        {
            setImage("Explosion.png");
            Greenfoot.setWorld(new Background());
        }
        
    }

Line 7 in MMPlayer should fail. Remove that line.

If it crashes when you reset the project, then it is probably something in your world constructor or in the constructor of one of the object created during the creation of your world. You could start by showing your Background class constructor.

I think that can't be an issue for that, because there is only the command "super(1000, 750, 1)" and "prepare();". What I found out was that if I am in the "GameOver" world and restart everything it doesn't matter if I set the world to "Background" or "MainMenue". That means the problem almost has to be in the world "Background". Here is the complete code of it: 
import greenfoot.*;
public class Background extends World
{
    private int imageCount = 0;
    private GreenfootImage bgImage = new GreenfootImage("Background.png");
    public int dif = MMPlayer.diff;
    public int height = 0;
    public void act() {
        imageCount += 4;
        drawBackgroundImage();
        height++;
        showText("Height:" + height + " / 3000",100,25);
        if(height >= 2980)
        {
            Greenfoot.setWorld(new LevelCompl());
        }
        switch (dif)
        {
            case 1:
            PlanetspawnerE();
            
            case 2:
            PlanetspawnerM();
            
            case 3:
            PlanetspawnerH();
        }
        MMPlayer.diff = 0;
    }
    public void drawBackgroundImage() {
        if (imageCount < -bgImage.getHeight()) 
        {
            imageCount -= bgImage.getHeight();
        }
        int temp = imageCount;
        getBackground().drawImage(bgImage, 0, temp);
        getBackground().drawImage(bgImage, 0, temp - bgImage.getHeight());
    }
    public Background()
    {    
        super (1000,750,1);
        prepare();
    }

The only thing that looks really off to me is in your 'drawBackgroundImage' method where you compare 'imageCount to a large negative value; yet, the value of the field is increasing and will never get below '-bgImage..getHeight()'. Change line 31 to: 
if (imageCount > bgImage.getHeight())

That fixed another problem of mine but not my main problem :( Probably it's just Greenfoot which is bugging a bit, like I have never had an errorlog... However thanks for trying!

Please post your GameOver class code for inspection. Possibly it may be a factor.
