TweenService on a model?

[Bylocks]

So I am making a door sliding system like a supermarket would have.

Here is my current set up

Inside the module, I create the tween movements and send them back, and play the tweens in the Touched script. Am I doing anything wrong in the module?

Module Tween Script

local Doormodule = {}
local Door1 = script.Parent.Door1.PrimaryPart
local Door2 = script.Parent.Door2.PrimaryPart
local TweenService = game:GetService("TweenService")
	
function Doormodule.DoorClose()
	
	local Door1goal = {}
	Door1goal.CFrame = CFrame.new(-12.8892326, 4.28804588, 62.0518227, 0, 0, 1, 0, 1, -0, -1, 0, 0)
	local Door2goal = {}
	Door2goal.CFrame = CFrame.new(-12.8892326, 4.25794125, 66.4844589, 0, 0, 1, 0, 1, -0, -1, 0, 0)
	 
	
	local tweenInfo = TweenInfo.new(1, Enum.EasingStyle.Quad, Enum.EasingDirection.InOut, 0, false)

	local tween1 = TweenService:Create(Door1, tweenInfo, Door1goal)
	local tween2 = TweenService:Create(Door2, tweenInfo, Door2goal)
	 
	return {tween1, tween2}
end

Thanks, Bylocks!

Unfortunately the TweenService will only touch individual instances. And to move a model, you can’t just set the primary part’s CFrame. Instead, you have to go through the SetPrimaryPartCFrame() method on the model, which will move all the other parts relative to the primary part for you.

Personally I use a custom Tween object that I created, which lets me pass a callback function, which allows me to do custom tweens.

Please do beware of using SetPrimaryPartCFrame for things like tweening, as it can cause your model to break apart with noticable gaps.

How do you use CFrame for the children of a model

Hey there! Looking at your code snippet in OP, it looks like a pretty small change in rotation of the model’s parts - which makes me think you’re actually wanting to repeatedly change the child/descendant objects of the model. If that is indeed your goal here, and you want to rotate the model instead of individually on each brick in the model to rotate around itself, I would advice against using SetPrimaryPartCFrame. But why? Look at the following video, and you’ll notice the results of misus…

:SetPrimaryPartCFrame() gradually offsets component parts

I made an animated barrier thing that uses :SetPrimaryPartCFrame() to move portions of the barrier. Here is its progress over time: When I first open it up in run mode: [image] I minimized studio and left it alone for a while. A little short of an hour later and it’s turned into this: [image] Notice how some of the pieces are no longer connected. Leaving it for a day resulted in this: [image] Here is a picture that shows the individual models: [image] local interpolation = require(scri…

However, it’s not quite relevant if you don’t have any rotations involved

There is a method in this thread that allows you to do something similar

Tweening Models

I been working with the Tween Service for awhile and it’s been doing me absolute wonders on my productivity, however it has a drawback. I can’t seem to use it on models. Anyone know a good method that’s cheap on performance such as the server to perform tweens on models? I know there is lerp but is there another option?

I’ve made an animation system before that’ll tween groups of parts. All I did was just have a function loop through and find all the parts in the model and tween them individually. Still did it all at once, or, seemingly.
