I have a GUI with a base Background frame with sizing {1, 0, 1, 0} which contains all the other UI elements inside. However, when I try to use an Aspect Ratio constraint on that background frame, the UI elements have different positions across different devices even though I want to maintain a fullscreen sizing. The reasoning for the constraint is to maintain an equal size of the items within that background across all devices.
Wait, why would you need a aspect ratio constraint on the background? It is after all a background that is gonna fill the screen. Just set the size to (1,0,1,0)
Ah, convert your UI contents position and size to Scale (the 1st and 3rd numbers of UDim2: {1,0,1,0})
I use a plugin to do this but you can easily change it to 1,0,1,0 and reposition
