If you use UIListLayout frequently in your games, you’ve been looking for a method to fix it.
I’ve been thinking of some way to run it automatically
and arrived in a simple mathematical form and very practical and Functional! This code will help you a lot when you are creating a UI that uses Clone () as for example a “Top Global”.
How I made this code:
Basically to fix the UIListLayout I multiplied the default size (Y.Scale) (before modifying according to the ScrollingFrame) by How Many Frames will be inside the ScrollingFrame, and then changed the value of Scrolling.Cavansize to the Result.
then I created a Loop to adjust all the children of ScrillingFrame, to adjust their size I used the standard size (Y.Scale) of the Frame (Clone()) divided by the Size of CanvanSize (the result above), thus the size of each child within the ScrollingFrame it had adapted to the size of the platform.
Note: For this function you need to set the height in Scale.
Fix Code:
for i = 1,10 do
local Clone = script.Frame:Clone()
Clone.Name = "Number: "..i
Clone.Parent = ScrollingFrame
------Fix------
local CanvaValue = Clone.Size.Y.Scale*(i)
ScrollingFrame.CanvasSize = UDim2.new(0,0,CanvaValue,0)
for i,v in pairs(ScrollingFrame:GetChildren()) do
if v.Name ~= "UIListLayout" then
v.Size = UDim2.new(1,0,Clone.Size.Y.Scale/CanvaValue,0)
end
end
------end------
end
I hope I helped you.
