listController

function list.dynamicTruncateCanvas(dir)
	local x = dir:GetChildren()
	local scale = 0
	local offset = 0
	for i = 1,#x do
		if x ~= nil and x.ClassName ~= "UIListLayout" then
			scale = scale + x.Size.Y.Scale
			offset = scale + x.Size.Y.Offset
		end
	end
	dir.CanvasSize = UDim2.new(0, 0, scale, offset)
end

Line 36 = Line 7

I don't see why it won't work, its gets as far as x.Size (Confirming this is getting the right objects) but for some reason fails on getting the Y attribute. Anyone know what is going on?

Please dont edit the table. See the comments below!

function list.dynamicTruncateCanvas(dir)
    local x = dir:GetChildren()
    local scale = 0
    local offset = 0
    for i = 1,#x do
        local x = x[i] -- set it to the actual object
        if x ~= nil and x.ClassName ~= "UIListLayout" then
            scale = scale + x.Size.Y.Scale
            offset = scale + x.Size.Y.Offset
        end
    end
    dir.CanvasSize = UDim2.new(0, 0, scale, offset)
end

If this helps, please mark as a solution!

Metatable out!

While this wouldn't have fixed it exactly, it did make me realise that I somehow forgot [i]. Thanks.
