I'm trying to make a (simple) mobile game that works on multiple screen sizes and aspect ratios. My idea was to create a large layout and then have a relatively small viewport. I can then use a scale outer to run fullscreen and just set an invisible bounding block to the edges of the screen.
set width = viewportright(0)-viewportleft(0)
set height = viewportbottom(0)-viewporttop(0)
But I don't know if it's working. My width always seems to change whether I change the width OR height of my browser window. Likewise my height never changes.
