How do I make a jail cell use tween service?

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Trying to make a jail cell use tween service.

  2. What is the issue? the jail cells doesn’t move smoothly.

  3. What solutions have you tried so far? Try to change the code but still doesn’t move smoothly.

– Code that doesn’t use tween service
for i = 0,6,0.2 do


script.Parent.Door.CFrame = script.Parent.Door.CFrame +*(-i),0,0)



for i = 0,6,0.2 do


script.Parent.Door.CFrame = script.Parent.Door.CFrame +*(i),0,0)


script.Disabled = true

How do I change this code to use tween service instead?

Here is a basic Tween Animation that you could modify to your liking:

local tweenInfo =
1, -- Time
 Enum.EasingStyle.Linear, -- EasingStyle
Enum.EasingDirection.Out, -- EasingDirection
0, -- RepeatCount (when less than zero the tween will loop indefinitely)
false, -- Reverses (tween will reverse once reaching it's goal)
0 -- DelayTime

local tween = TweenService:Create(script.Parent.Door, tweenInfo, {CFrame = "final destination CFrame"})


Hope this helps!

Ok does cframe mean like how far it goes?

local TweenService = game:GetService('TweenService') -- Get the TweenService

local tweenInfo =, Enum.EasingStyle.Sine, Enum.EasingDirection.InOut) -- Create a TweenInfo for your tween

local PartToTween = workspace.Part; -- Find a part that you want to tween

local CurrentCFrame = PartToTween.CFrame; -- The original CFrame (The Closed Position)
local NewCFrame = PartToTween.CFrame *, 0, 0) -- The Open CFrame

local NewTween = TweenService:Create(PartToTween, tweenInfo, {CFrame = NewCFrame}) -- Create a new Tween
NewTween:Play() -- Runs the CFrame

You will need to run a tween when you want to Open the door and Close the door unless you set Reverse to true in the TweenInfo.

Here’s more information so you can learn how it all works:
Information on TweenService
Information on TweenInfo
Information on TweenService:Create()


A CFrame represents both Position and Orientation. Setting the CFrame in the third argument, the “goal” table, will make it tween until it reaches that Position and Orientation. So it’s not “how far it goes” so much as “where it goes”. It’ll always go to the same position, regardless of where it started.

Thanks! I will use this and modify to work.


Also how do I add a delay for when it reverses?

Unfortunately that’s a limitation with the reverse aspect of tweening currently unless I’m mistaken. It’s simple enough to have two separate tweens for the Opening and Closing, and you can use the .Completed event to yield until it has finished tweening:

local openTween = TweenService:Create(Part, tweenInfo, {CFrame = OpenCFrame})
openTween.Completed:Wait() -- Yields the code until the tween is completed
local closeTween = TweenService:Create(Part, tweenInfo, {CFrame = CloseCFrame})
closeTween.Completed:Wait() -- " .. "
