AspectRatio of UIAspectRatio constraint

Help and Feedback Scripting Support
#1

I am attempting to make a plugin that automatically adds a UIAspectRatio constraint but I am not sure how to get the AspectRatio property automatically. Is there a formula to calculate this

#2

You divide the absolute size in X by the absolute size in Y. A frame that is twice as long as it is tall would have an aspect ratio of 2.

What if the number is too long

#4

I don’t really know what you mean by that, sorry.

its like 2.093582935729374294719247129319237123917293712937

then i tried entering it manually into the property and it just becomes 0

#6

The properties window only allows you to paste up to 3 decimals, yes. Lua doesn’t have this restriction since it’s not the properties window and numbers in Lua are not bound to a certain length in decimal notation or anything.

i see, thank you!

#8

i tried it but it keeps becoming 1

Script:

script.Parent.MouseButton1Click:connect(function()
	for _, v in ipairs(game.Selection:Get()) do 
		if v.ClassName == "ImageLabel" or v.ClassName == "ImageButton" or v.ClassName == "Frame" or v.ClassName == "TextLabel" or v.ClassName == "TextButton" or v.ClassName == "TextBox" then
		local clone = Instance.new("UIAspectRatioConstraint")
		clone.Parent = v
		local x = v.AbsoluteSize.X
		local y = v.AbsoluteSize.Y
		local ratio = x/y
clone.AspectRatio = ratio
	wait(.1)
	print("UI Scaled")
		end
		end
end)

You only need a UIAspectRatioConstraint in the main frame of the GUI

I know but when i made the script do the math, it keeps getting 1

#12

Did you try printing the ratio? And if so is it also 1?

#13

yes

#14

I even made it print the absolute sizes before doing the math and it is accurate. But when it divides, it keeps getting “1”

#15

You insert the aspect ratio constraint before determining the ratio. The default value of the aspect ratio is 1. The size of the object gets adjusted to be aspect ratio 1 before you determine the ratio.

Put the lines where you determine ‘ratio’ before the ‘clone.Parent = v’.

I wanna know what property I should use from FitWithinMaxSize and ScaleWithParentSize.
This happens when i use FitWithinMaxSize
On my screen :

On another device:

Edit: Kinda fixed it by using one frame for all.
