Tween going the wrong place!

Hello developers!

I am working on an elevator door.
While scripting the open tween, I noticed an issue. Every time the tween plays, it goes to it’s last known position. Example: If I go to floor 2 and it was at floor 1 the door opens and at the same time goes to floor 1

Script 
--- TweenService and TweenTimes ---
local TweenService = game:GetService("TweenService")
local TweenTime1 = TweenInfo.new(2)
local TweenTime2 = TweenInfo.new(12)

--- Objects ---
local Door1 = script.Parent.Parent.Parent.Parent.Parent.Parent:WaitForChild("Door1",5)
local Door2 = script.Parent.Parent.Parent.Parent.Parent.Parent:WaitForChild("Door2",5)
local Rope1 = script.Parent.Parent.Parent.Parent.Parent.Parent:WaitForChild("Top",5).RopeConstraint1
local Rope2 = script.Parent.Parent.Parent.Parent.Parent.Parent:WaitForChild("Top",5).RopeConstraint2

--- ClickDetector And Values ---
local Click = script.Parent:WaitForChild("ClickDetector" ,5)
local Moving = script.Parent.Parent.Parent.Parent.Parent.Parent:WaitForChild("Moving",5).Value
local FloorValue = script.Parent.Parent.Parent.Parent.Parent.Parent:WaitForChild("FloorValue",5).Value

if Door1 ~= nil and Door2 ~= nil and Click ~= nil then
	Click.MouseClick:Connect(function(Player)
		--- Close Tweens ---
		local Door1CloseGoal = {}
		Door1CloseGoal.Position = Vector3.new(Door1.Position.X, Door1.Position.Y, Door1.Position.Z - 1.5)
		local Door1Close = TweenService:Create(Door1, TweenTime1, Door1CloseGoal)
		--------------------------------------------------------------------------------------------------
		local Door2CloseGoal = {}
		Door2CloseGoal.Position = Vector3.new(Door2.Position.X, Door2.Position.Y, Door2.Position.Z + 1.5)
		local Door2Close = TweenService:Create(Door2, TweenTime1, Door2CloseGoal)

		--- Open Tweens ---
		local Door1OpenGoal = {}
		Door1OpenGoal.Position = Vector3.new(Door1.Position.X, Door1.Position.Y, Door1.Position.Z + 1.5)
		local Door1Open = TweenService:Create(Door1, TweenTime1, Door1OpenGoal)
		--------------------------------------------------------------------------------------------------
		local Door2OpenGoal = {}
		Door2OpenGoal.Position = Vector3.new(Door2.Position.X, Door2.Position.Y, Door2.Position.Z - 1.5)
		local Door2Open = TweenService:Create(Door2, TweenTime1, Door2OpenGoal)
		--------------------------------------------------------------------------------------------------

		--- Rope Tweens ---
		--- Up Tweens
		local Rope1UpGoal = {}
		Rope1UpGoal.Length = 1.1
		local Rope1Up = TweenService:Create(Rope1, TweenTime2, Rope1UpGoal)
		--------------------------------------------------------------------------------------------------
		local Rope2UpGoal = {}
		Rope2UpGoal.Length = 1.1
		local Rope2Up = TweenService:Create(Rope2, TweenTime2, Rope2UpGoal)
		--- Down Tweens ---
		local Rope1DownGoal = {}
		Rope1DownGoal.Length = 23.005
		local Rope1Down = TweenService:Create(Rope1, TweenTime2, Rope1DownGoal)
		--------------------------------------------------------------------------------------------------
		local Rope2DownGoal = {}
		Rope2DownGoal.Length = 23.005
		local Rope2Down = TweenService:Create(Rope2, TweenTime2, Rope2DownGoal)

		if Moving ~= true and FloorValue ~= 1 then
			Moving = true
			FloorValue = 0
			workspace.Close:Play()
			Door1Close:Play()
			Door2Close:Play()
			Door1Close.Completed:Connect(function()
				wait(0.5)
				Rope1Down:Play()
				Rope2Down:Play()
				Rope1Down.Completed:Connect(function()
					wait(1)
					Moving = false
					FloorValue = 1
					workspace.Open:Play()
					Door1Open:Play()
					Door2Open:Play()
				end)
			end)
		end
	end)
end

Thanks! Waiting for a reply.

Hi!

Do you update the “CFrameToStartTweenAt” after you’ve moved the elevator?

Edit:

Also statements like

if Door1 ~= nil then

is like saying

if NotNil ~= nil then

Instead just do

if NotNil then

or in your case

if Door1 then
#3

Also instead of this:

Door1CloseGoal.Position = Vector3.new(Door1.Position.X, Door1.Position.Y, Door1.Position.Z - 1.5)

Take the Position, and apply the Z offset after, it’s way shorter.

Door1CloseGoal.Position += Vector3.new(0,0,-1.5) -- Haven't tested if "+=" works with Vector3, if not do the one below
Door1CloseGoal.Position = Door1CloseGoal.Position + Vector3.new(0,0,-1.5)
#4

Neither of the options work.

Don’t know what you mean by that. Can you explain what it exactly does?

#5

Please let me know the output, it should work the same as yours.

When you start a tween, and you want to change it’s position, you start out with defining what position it should start from, and go to. For example

TweenGoal = {Position = DoorPosition + Vector3.new(0,10,)}

That first “DoorPosition” is the “CFrameToStartTweenAt” or in this case “PositionToStartTweenAt”
