Issue with CFrames and Tweening

[TeamDreams123 (sillygoober)]

Hey developers,

So I’m getting this error in the console: TweenService:Create no property named 'CFrame' for object 'Door'

Here’s my code: (and yes all the locals go to the right place)

local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local TweenService = game:GetService("TweenService")

local NoTrinketEvent = ReplicatedStorage:WaitForChild("Events"):WaitForChild("NoGodsTrinket")
local TrinketSuccess = ReplicatedStorage:WaitForChild("Events"):WaitForChild("TrinketRemoved")

local Door = workspace.InsideTemple.Gate.Door
local DoorOpen = Door:FindFirstChild("DoorOpen")
local DoorClose = Door:FindFirstChild("DoorClosed")
local OpenSound = Door.Door:FindFirstChild("DoorOpen")
local CloseSound = Door.Door:FindFirstChild("DoorClosed")

local function tweenDoor(open) -- here
	local goal = {}
	if open then
		goal.CFrame = DoorOpen.CFrame
	else
		goal.CFrame = DoorClose.CFrame
	end
	local tweenInfo = TweenInfo.new(3, Enum.EasingStyle.Quad, Enum.EasingDirection.Out)
	local tween = TweenService:Create(Door, tweenInfo, goal)
	tween:Play()
end -- to here ( i think )

local function onProximityPromptTriggered(proximityPrompt, player)
	local character = player.Character
	if not character then return end

	local backpack = player:FindFirstChild("Backpack")
	if not backpack then return end

	local trinket = backpack:FindFirstChild("GodTrinket")
	if trinket then
		trinket:Destroy()
		TrinketSuccess:FireClient(player)
		script.Parent.Enabled = false
		tweenDoor(true)
		task.wait(90)
		tweenDoor(false)
		task.wait(5)
		script.Parent.Enabled = true
	else
		NoTrinketEvent:FireClient(player)
	end
end

local proximityPrompt = script.Parent
proximityPrompt.Triggered:Connect(function(player)
	onProximityPromptTriggered(proximityPrompt, player)
end)

I indicated where in the script I think it’s erroring with ‘here’ and ‘to here’
Thank you for your help!

its erroring because Door is a model which doesnt have the CFrame property

Introduction to Tweening Models

Edit (06/30/2021): Due to the release of the new pivot APIs and the thankful deprecation of SetPrimaryPartCFrame, the legacy method of CFraming is now also appropriate and you do not necessarily need to use this welding method. Do note that the pivot CFrame is different from the PrimaryPart CFrame though, so you will have to account for that when writing your proxy objects. Edit (05/31/2023): Roblox has an official code sample for model tweening! It’s very lightweight and covers the necessities…
