Also just to note you could leave it on a letterbox knowing full well that it drops down to scale outer in cocoonjs. This allows your project to look nice in browser with letterbox as well as in cocoonJS with scale outer.
Thanks a lot, I managed to center the layout now, but I have a new, different problem:
I have to set "Fullscreen scaling: Low quality" because my game is 32x32 px and in order to display correctly it needs to render first, then scale. Unfortunately, depending on the final resolution this screws up the rendering. For example one line of pixels doesnt even show up, screwing up the complete layout.
I drew up a quick explanation of the problem.
Choosing "Fullscreen scaling: High quality" seems to fix the problem, but then some objects render like this
instead of this
And I need all objects to be pixellated like shown in the second image.
Can anyone help me out here?
