I have a little problem. The object (a rover) should scan stone but no text is getting out. Can somebody help? public void anzeigen(String pText) { loeschen(); bild = new GreenfootImage(pText, 30, null, null); getImage().drawImage(bild, 8,0); }

Use explicit Color values instead of null when creating your GreenfootImage object. For example: 
bild = new GreenfootImage(pText, 30, Color.gray, new Color(0, 0, 0, 0));

Try 'GRAY', with all caps ( or 'new Color(128, 128, 128)' ).
