Getting position of frame in a scrolling frame

Help and Feedback Scripting Support

Im making a rolling system in my game im using a Scrolling Frame for it but i cant figure out how i would get the correct position of my item in the frame

this is the script

function self.Open(itemFolder : Folder, multipliers : {}?)
	local item = events:WaitForChild("Roll"):InvokeServer(itemFolder, multipliers)

	local randomPosition = math.random(50, 58)
	local targetFrame
	
	for i = 1,60 do
		local frame = assets.Template:Clone()
		frame.Parent = scrollingFrame

		if i == randomPosition then
			targetFrame = frame
			self.InitItem(frame, itemFolder, item.name)
		else
			local randomItem = events:WaitForChild("Roll"):InvokeServer(itemFolder, multipliers)
			self.InitItem(frame, itemFolder, randomItem.name)
		end
		
		frame.Name = i
	end

	local position = self.calculatePosition(targetFrame)
	local canvasPositon = Vector2.new(position, 0)

	print(item.name)
	print(canvasPositon)

	local info = TweenInfo.new(10, Enum.EasingStyle.Exponential, Enum.EasingDirection.Out)
	local tween = tweenService:Create(scrollingFrame, info, {CanvasPosition = canvasPositon})

	tween:Play()
end

function self.calculatePosition(targetItem: Frame)
	local itemCanvasX = targetItem.AbsolutePosition.X - scrollingFrame.AbsolutePosition.X + scrollingFrame.CanvasPosition.X
	return itemCanvasX
end

and self.calculation() isnt calculating correctly
does anybody know any fixes?

instead of using math.random to choose a specific frame, you could just use a constant index like 50, so the time consumed by each roll is the same and you dont have to calculate too much stuff. this way you could perhaps calculate the canvasposition using the AbsoluteSize(s) of the frames on the left of the 50th frame.
