How can i make this gui go across the screen?

I was testing out a script i made, and i wanted to make a gui go across the screen. This script is not working for some reason. Can you please help me?

local background = script.Parent
for i = -1050, 0, 10 do
	background.Position.X.Offset = UDim2.new(i)
	wait()
end

:TweenPosition, :TweenSize, and :TweenSizeAndPosition

Alrighty, let's get to it.

You're wanting to do something that already exists as a function for GuiObjects.. Tweening is fairly easy, if you know how CFrame.lerp() works. Tween is similar.

Also assuming you mixed up Scale,Offset.

Scale is first, Offset is second.

UDim2.new(Xscale, Xoffset, Yscale, Yoffset)

-- || Variables ||
local Background = script.Parent
Background:TweenPosition(UDim2.new(0,-1050,0,10), Enum.EasingDirection.In, Enum.EasingStyle.Quad, 1, false)

If you're really wanting to do it the way you've previewed to us, I guess I'll show that way too?

Comment that you want that way if you'd like, but for now. Best of luck!
