room_set_width(roomname, display_get_width()) room_set_height(roomname, display_get_height())repeated for all rooms in the actual game, followed by
window_set_fullscreen(true) room_goto_next()This works, because GM allowed rooms to have different sizes. However it does this no more due to a design decision. But I'd still like my games to be full screen without scaling, so I'd like to change the actual room size (so that I can use room_width and room_height to position stuff) and have a matching display size as well.
How should I do this?
