Why does it keep doing this?

I’m trying to make a helmet protraction and retraction script that allows the helmet to tween over the player’s head and back, but it keeps acting weirdly as seen in the video.

This is the script so far:

local TweenService = game:GetService("TweenService")

local Head = script.Parent
local Helmet = Head.Helmet

local Info = TweenInfo.new(
	1,
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.InOut,
	0,
	false,
	0
)

local Weld = Instance.new("Weld")
Weld.C0 = CFrame.new(0,0,0)
Weld.C1 = CFrame.new(0,0,1)

Weld.Part0 = Head
Weld.Part1 = Helmet
Weld.Parent = Head

local function CloseHelmet()
	local CloseGoal = {}
	CloseGoal.C1 = CFrame.new(0,0,0)
		local Tween = TweenService:Create(Weld,Info,CloseGoal)
	Tween:Play()
end

local function OpenHelmet()
	local OpenGoal = {}
	OpenGoal.C1 = Helmet.CFrame * CFrame.new(0,0,-2)
	local Tween = TweenService:Create(Weld,Info,OpenGoal)
	Tween:Play()
end

while true do
	CloseHelmet()
	
	wait(2)
	
	OpenHelmet()
	
	wait(2)
	

	
end

How do I make it so that the helmet slides back as intended? And why is it zooming from the baseplate to the head and back?

Hello, the problem is Helmet.CFrame here.
You see, C1 is an offset, so there is already no need to multiply it’s CFrame.

Ah that fixes it, thank you man.
