Model won't tween

Help and Feedback Scripting Support
#1

I’ve tried everything, every video and forum post there is to find.

I have a model of a dumbbell with the two part: handle and the dumbell. in the handle is a weld to weld the handle and dumbbell, the handle is the only part that’s anchored and it’s the primary part.

It doesn’t matter what I script sometimes it won’t move or only the dumbbells, never the handle.

tweenService:Create(newDumbell.PrimaryPart,TweenInfo.new(dumbellMoveDuration),{Position = Vector3.new(0,newDumbell.PrimaryPart.Size.Y + 5,0)}):Play()

I’ve also tried CFrame tweening

I’ve had the same issue before. I use a manual weld rather than weld constraints which works perfect for tweening. Another check to make sure of is that nothing is anchored if it’s a tool or if it’s a normal model then only the primary part is anchored.
I use this plugin to make the manual welds easy to use: https://create.roblox.com/store/asset/148570182/Weld

Have you seen this post: Tweening Models

I forgot the new method but what I do remember is you can use a cframe value or something like that and tween the value for models.

Example:

local v = Instance.new("ObjectValue")
v.Value = model:GetPivot()
v.Changed:Connect(function()
	model:SetPivot(v.Value)
end)

local tween = TweenService:Create(v, tweenInfo, { Value = v.Value + CFrame.new(0, 5, 0) })
tween:Play()

tween.Completed:Connect(function()
	v:Destroy()
end)

no you fucking didnt cause istg i deadass saw 3 topics about the same thing this WEEK doing the same exact thing ur doing :sob: :sob:

cframe tweening AFAIK is the only method that will work, do sm like this

-- assume that TweenService reference exists already

local dumbellOrigin = newDumbell.PrimaryPart.CFrame
local dumbellTweenInfo = TweenInfo.new(dumbellMoveDuration)
local dumbellTween = tweenService:Create(newDumbell.Handle, dumbellTweenInfo, {
     CFrame = dumbellOrigin + Vector3.new(0, 5, 0)
}) -- if the handle is named Handle then go ahead, otherwise replace Handle in this code
-- for the actual name of the handle

print(newDumbellHandle:FindFirstChildOfClass("Weld")) -- replace newDumbellHandle with something 
print(newDumbellHandle:FindFirstChildOfClass("WeldConstraint")) -- also replace
dumbellTween:Play()

-- if the outputs are nil, you definitely forgot to do something

idk what the problem is if this doesnt work, best solution is to just post the view of the dumbell in the explorer and put it here so we can pick apart what went wrong

The prints aren’t nil and I have already tried this method.

#8

are you sure that nothing but the handle is anchored?

If you don’t mind the movement being linear, you could move the newDumbell model using the MoveTo method and interpolate between the model’s current position and the target position:

local RunService = game:GetService("RunService")


local function moveDumbell(newDumbell: Model, dumbellMoveDuration: number?)
	local dumbellMoveDuration = dumbellMoveDuration or 1 -- This will make the move duration default to 1 second if the second argument isn't provided

	local startPosition = newDumbell:GetPivot().Position
	local targetPosition = Vector3.new(0, newDumbell.PrimaryPart.Size.Y + 5, 0)

	local x = 0

	local connection
	connection = RunService.Heartbeat:Connect(function(deltaTime: number)
		x = math.min(x + (deltaTime / dumbellMoveDuration), 1)

		newDumbell:MoveTo(startPosition:Lerp(targetPosition, x))

		if x == 1 then
			connection:Disconnect()
		end
	end)
end

Example on how to call the function:

moveDumbell(newDumbell, 4) -- Using 4 as the second argument would result in the dumbell taking 4 seconds to reach the target position
