It is in both world classes of my stargate space shooter. here are error and method. here is the error:

and here the method:

        super(1000, 600, 1); 
        GreenfootImage background = new GreenfootImage(1000, 600);
        scrollingImage = getScrollingImage(1000, 600);
        background.drawImage(scrollingImage, 0, 0);
        setBackground(background); 
        if(UserInfo.isStorageAvailable())  
        {
            UserInfo playerData = UserInfo.getMyInfo();
            userImg = playerData.getUserImage();
            userImage = true;
        } else
        {
            userImage = false;
        }
        setPaintOrder(ScoreBoard.class, JumperShield.class, Jumper.class, Enemies.class, Enemies_attack.class, HPBar.class, HWBar.class, LWBar.class, Explosion.class,Drone.class, N_bomb.class, Powerup.class);

        addObject(shbar, getWidth() / 2, 80);
        addObject(jumper, 43, 314);
        Greenfoot.start();
        opening.play();
    }

        if(UserInfo.isStorageAvailable()) {
            if(UserInfo.getMyInfo() != null) {
                UserInfo playerData = UserInfo.getMyInfo();
                userImg = playerData.getUserImage();
                userImage = true;
            }
        }

UserInfo.isStorageAvailable() only tells you, whether your scenario is run on the greenfoot.org website. UserInfo.getMyInfo() will return null when you aren't logged in to greenfoot.org so you should check for this as well. I always do it like that, so it should work.

now it marks your new line, same error

        if(UserInfo.isStorageAvailable())  
        {
            if(UserInfo.getMyInfo() != null)  // this line is marked
            { 
                UserInfo playerData = UserInfo.getMyInfo();
                userImg = playerData.getUserImage();
                userImage = true;
            } else
            {
                userImage = false;
            }
        } else
        {
            userImage = false;
        }

You could try to delete storage.csv from your scenario's folder and then try it again. There is nothing wrong with the code, at least I don't see it.

@erdelf: trash1000's suggestion was correct. This error can only occur if the storage.csv file gets messed up. Can you tell me: did you manually edit it at all, or did this problem come about solely from Greenfoot writing/reading that file?

I manually edited it, I changed 20 to 200. Another question; Is it needed that I delete the storage.csv before uploading?

@erdelf: The storage mechanism online is totally separate from the CSV. So the online scores won't be affected by the CSV being present. But I did just check, and your storage.csv does get uploaded as part of the scenario! So when other users open it in Greenfoot, they will get your storage.csv. Hmmm, not sure if that's a bug or a feature!
