I'm trying to use a background image instead of having to create a large tileset for rooms inside a house. I have a large background image (2240x1600) and I created a scene with the same dimensions. My screen size is set at 1280x800. When I test the scene my actor doesn't start where I placed it and trying to control it runs in to what seems like invisible walls.
However, when I enable to repeat the background it works fine. Does my screen size matter in this case, and why would the background need to repeat if it's the exact same size as my scene?
