Get AbsoluteContentSize without UIListLayout?

Hey, I wanted to do a serverside GUI creator, but when creating a scrolling frame that automatically adjusts its size based on the absolute content size, I got stuck. I just didn’t know what to do to get that working. Any help? The following is the code I have so far: (problem is on the last line)

local Commands = Instance.new("ScreenGui")
local main = Instance.new("Frame")
local close = Instance.new("TextButton")
local minimise = Instance.new("TextButton")
local Title = Instance.new("TextLabel")
local Frame = Instance.new("Frame")
local ScrollingFrame = Instance.new("ScrollingFrame")
local UIListLayout = Instance.new("UIListLayout")
Commands.Name = "Commands"
Commands.Parent = playerUI
Commands.ZIndexBehavior = Enum.ZIndexBehavior.Sibling
Commands.ResetOnSpawn = false
main.Name = "main"
main.Parent = Commands
main.BackgroundColor3 = Color3.fromRGB(136, 133, 123)
main.BorderSizePixel = 0
main.Position = UDim2.new(0.17509158, 0, 0.229166672, 0)
main.Size = UDim2.new(0.245421246, 0, 0.029947916, 0)
main.Active=true
main.Selectable = true
close.Name = "close"
close.Parent = main
close.BackgroundColor3 = Color3.fromRGB(186, 122, 122)
close.BorderSizePixel = 0
close.Position = UDim2.new(0.939750433, 0, 0, 0)
close.Size = UDim2.new(0.0597014911, 0, 1, 0)
close.Font = Enum.Font.SourceSans
close.Text = ""
close.TextColor3 = Color3.fromRGB(0, 0, 0)

Frame.BackgroundColor3 = Color3.fromRGB(126, 123, 114)
Frame.BorderSizePixel = 0
Frame.Position = UDim2.new(0, 0, 1, 0)
Frame.Size = UDim2.new(1, 0, 0.615554094, 0)

    TextLabel.Text=o
end
main.Draggable=true
ScrollingFrame.CanvasSize=UDim2.new(0,0,0,???) -- SET THE CANVAS SIZE BASED ON CONTENT INSIDE

You should be getting the content size by iterating over the children of the UI and then incrementing their absolute position. So something like:

local size = 0
for _, v in ipairs(UI:GetChildren()) do
    size += v.AbsoluteSize.Y
end
ScrollingFrame.CanvasSize = UDim2.new(0, 0, 0, size)
3

An alternative that requires no code would be to set AutomaticCanvasSize to Y on the ScrollingFrame. It will automatically figure out the size of the contents and adjust accordingly.

Unfortunately no luck with both of your answers (@GrayzcaIe ), I don’t know why but it just won’t budge.

Any further help would be greatly appreciated.

After lots of tests, I found out that I had to multiply the label’s size by 1.6, probably for some padding reason that is currently unknown to me.
