Issues tweening a model

Help and Feedback Scripting Support
#1

Hey devs,

I have an issue tweening a model.

This is my code:

local model = script.Parent
local targetPosition = Vector3.new(-290.7, 10.717, 35)
local tweenTime = 10

local TweenService = game:GetService("TweenService")
local tweenInfo = TweenInfo.new(tweenTime, Enum.EasingStyle.Quad, Enum.EasingDirection.Out)

local primaryPart = model.PrimaryPart
if primaryPart then
	local tween = TweenService:Create(primaryPart, tweenInfo, {CFrame = CFrame.new(targetPosition)})
	tween:Play()
else
	warn("No PrimaryPart found in the model. Please set a PrimaryPart for the model.")
end

It gives me the warning No PrimaryPart found in the model. Please set a PrimaryPart for the model.

Thank you.

You need to set the primary part in the properties.

I set it, and it worked, there’s no errors.

But now the issue is… the model won’t tween.

#4

Try welding the parts in the model to the primary part.

How can I do that? There’s like a thousand parts in the model.

#6

There is a plugin where you can just shift select the parts and press weld on the plugin.

Make sure that the first selected part is the primary part though.

Can I weld the whole model? char

You can also make a weld script that welds all the parts in the model to the primary part.

How? Can you give me a sample of the code? @BlurBaviaan

This will probably do it.

local model = script.Parent
local targetPosition = Vector3.new(-290.7, 10.717, 35)
local tweenTime = 10

local TweenService = game:GetService("TweenService")
local tweenInfo = TweenInfo.new(tweenTime, Enum.EasingStyle.Quad, Enum.EasingDirection.Out)



local primaryPart = model.PrimaryPart

for _,part in pairs(model:GetChildren()) do
	if part ~= primaryPart then
		local weld = Instance.new('Weld')
		weld.Name = part.Name
		weld.Parent = primaryPart
		weld.Part0 = primaryPart
		weld.Part1 = part
	end
end

if primaryPart then
	local tween = TweenService:Create(primaryPart, tweenInfo, {CFrame = CFrame.new(targetPosition)})
	tween:Play()
else
	warn("No PrimaryPart found in the model. Please set a PrimaryPart for the model.")
end

How can I fix that?

#12

Do you have models in your model that you want to move?

#13

Yes. I do, they are lights, chairs and stuff like that.

#14

Everything must be a part in the model. So you shall ungroup the models in the model if that is possible

I have ungrouped everything and still has an error but instead of model it’s a script. Do I need to put the script outside of the model? Expected BasePart got Script for Weld:Part1.

#17

Edited the code* Also only anchor the primary part in the model.

#18

Okay so here is the fixed code, make sure all parts are unachored, only primary part can be anchored.

local model = script.Parent
local targetPosition = Vector3.new(-290.7, 10.717, 35)
local tweenTime = 10

local TweenService = game:GetService("TweenService")
local tweenInfo = TweenInfo.new(tweenTime, Enum.EasingStyle.Quad, Enum.EasingDirection.Out)



local primaryPart = model.PrimaryPart

if primaryPart then

	for _,part in pairs(model:GetChildren()) do
		if part ~= primaryPart then
			if part:IsA('BasePart') then
				local weld = Instance.new('WeldConstraint')
				weld.Name = part.Name
				weld.Parent = primaryPart
				weld.Part0 = primaryPart
				weld.Part1 = part
			end
			if part:IsA('Model') then
				for _,part2 in pairs(part:GetChildren()) do
					local weld = Instance.new('WeldConstraint')
					weld.Name = part2.Name
					weld.Parent = primaryPart
					weld.Part0 = primaryPart
					weld.Part1 = part2
				end
			end
		end
	end


	local tween = TweenService:Create(primaryPart, tweenInfo, {CFrame = CFrame.new(targetPosition)})
	tween:Play()
else
	warn("No PrimaryPart found in the model. Please set a PrimaryPart for the model.")
end

Is that the code I just send? Because it works in my workplace.

Can you send a screenshot of your model in the explorer?
