Tween not working for weld (URGENT HELP NEEDED)

[YellowBannana898 (BananaDev)]

Hey I’m trying to tween a door. I made a primary part which is invisible and covers the entire door. I connected all the welds to that part, and tried to tween it. However, only the primary part seems to be getting tweened. If anyone knows why this might be, please feel free to let me know. Your help will be appreciated.
Code:

local door1 = door.Door1

local door2 = door.Door2

local doorTweenInfo = TweenInfo.new(1,

Enum.EasingStyle.Sine,

Enum.EasingDirection.Out,

0,

false,

0

)

local door1TweenGoals = {CFrame = CFrame.new(Vector3.new(door1.PrimaryPart.Position + Vector3.new(door1.PrimaryPart.Size.X, 0, 0)))}

local door2TweenGoals = {CFrame = CFrame.new(Vector3.new(door2.PrimaryPart.Position - Vector3.new(door2.PrimaryPart.Size.X, 0, 0)))}

local door1Tween = TweenService:Create(door1.PrimaryPart, doorTweenInfo, door1TweenGoals)

local door2Tween = TweenService:Create(door2.PrimaryPart, doorTweenInfo, door2TweenGoals)

door1Tween:Play()
door2Tween:Play()

Your weld constraints seem to be disabled. Have you enabled them?

[YellowBannana898 (BananaDev)]

Yes, indeed. They are enabled.

[YellowBannana898 (BananaDev)]

Update: I tried changing it’s CFrame, like without tweening and it still only changes the CFrame for the primary part rather than the entire model. Maybe there’s perhaps something wrong with the weld constraints?

[InedibleGames]

unfortunately you cannot use tweenservice to tween models

@colbert2677

local tweenService = game:GetService("TweenService")
local info = TweenInfo.new()

local function tweenModel(model, CF)
	local CFrameValue = Instance.new("CFrameValue")
	CFrameValue.Value = model:GetPrimaryPartCFrame()

	CFrameValue:GetPropertyChangedSignal("Value"):Connect(function()
		model:SetPrimaryPartCFrame(CFrameValue.Value)
	end)
	
	local tween = tweenService:Create(CFrameValue, info, {Value = CF})
	tween:Play()
	
	tween.Completed:Connect(function()
		CFrameValue:Destroy()
	end)
end

but there is this!

[YellowBannana898 (BananaDev)]

but surely you should be able to tween a certain part connected to other parts?

[InedibleGames]

I believe unless you’re using setprimarypartcframe, it won’t work (not sure but from my experience it won’t )

@YellowBannana898

This method works, BUT it is highly deoptimized. Because:

@colbert2677

The bottleneck is that ValueObject. This whole method relies on it. The moment that ValueObject goes, you have a problem on your hands.

@colbert2677

SetPrimaryPartCFrame itself is terrible.

@colbert2677

• Introduces unnecessary overhead and overcomplication to a simple problem by adding more instances and management processes to your code.

What answer @InedibleGames is false, and you shouldn’t listen to his advice as this code is deoptimized. You can refer to this tutorial instead: Introduction to Tweening Models

[InedibleGames]

in that case then take a look at this too

Introduction to Tweening Models

Revisiting this tutorial after a long time for an important notice with regards to the bottom: specifically, where I note that you can also use other constraints for moving models and that a potential tutorial may be written up on that later (assuming I had the time to do so). In short: it’s not happening. I currently follow this tutorial myself for two of my group’s games and respectively each of them have had a glaring problem with regards to exploits based on network ownership. As a little …

[ItzMeZeus_IGotHacked (notzeussz)]

This has nothing to defend your side.

One, you showed a code that’s supposed not to be used because of the deprecated functions used in it. Then, I already pointed out why it is deoptimized and how to optimize it(which is using the new pivot API functions). You then show a post that counters nothing but explaining why constraints shouldn’t be use in tweening models.

Second, your post is also invalid. You should’ve read further before posting:

Introduction to Tweening Models

Hey developers! Coming by with an important update. First, let's start with the cool thing. …I’ve finally gotten around to adding a table of contents, woohoo! It’s right at the top of the thread before the introduction so now you can jump to parts of the tutorial rather than having to scale the entire thing to find a point or to get right to the good parts. This was a long time overdue. I still do recommend that newer developers read up until Section 5 to fully understand what we’re doing and…

Says the one who got rude when I was being nice the whole time. @luisgamercooI231fan

@InedibleGames

i was showing a post that also shows the downsides of models using constraints to be informative

And I corrected that flaw in my previous post.
