try using the project here, and also at https://turbowarp.org/1113755734?size=640x360 or with a different size finds the current height and width of the stage, and then finds its aspect ratio with the information. it's technically just simplifying a fraction lol you can't use this to make the contents of the project adapt to the stage size because x and y positions would be based on the stage's width and height at the same time. i tried this before and failed miserably (this note was added on 1/19/25 lol)
