Hey, I´m using danpost ImageScrollWorld (https://www.greenfoot.org/scenarios/19020) to move my Player around . My Problem is that I want tow Actors (e.g. Health & Mana Bar) to be on screen and unaffected by the scrolling. I tried to create a subclass as "Overlay" of the ImageScrollWorld and place my Actors on that but that did not work for me. Can someone point me in the right direction? Thanks in advance.
