@Roshan, it will work: getBackground().drawImage(new GreenfootImage(""+((char)8595), 20, Color.BLACK, new Color(0, 0, 0, 0)), 500, 500);

@SwaggyXiao, please refer to my Scrolling Tutorial scenario on image scrolling (see main text and link at bottom on "Actor follow scrolling code"). The scenario is located at: https://www.greenfoot.org/scenarios/18226

Good Morning, is there a way to add moving enemies when using an ImageScrollWorld like this one. I can't figure a code that lets the enemies move around and at the same time keep them in synch with the rest of the game moving with the player movements. Thank you for your time

@AnJoMorto, are you not creating them with a true boolean? addObject(new Enemy(), x, y, true);

@danpost oh yes I see. I only had the base code of the ImageScrollWorld from your scrolling tutorial (https://www.greenfoot.org/scenarios/18226). I just added the methods to add a scrollable object, and it works now. Thank you very much!
