Model wouldn't tween properly

Help and Feedback Scripting Support
#1

So I’m working on a interactive main menu for a new game that im working on but for some reason only the primary part of the model tweens even tho all the other parts of the model are welded to it and unanchored.

Video of the problem:

Code:

local UserInputService = game:GetService("UserInputService")
local TweenService = game:GetService("TweenService")
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

local v = script.Parent.PlayBut

UserInputService.InputChanged:Connect(function(input, gameProcessed)
	if gameProcessed then return end
	if input.UserInputType == Enum.UserInputType.MouseMovement then
		local mousePos = Vector3.new(mouse.X, mouse.Y, 1000)

		-- Get the rotation components from the CFrame
		local x, y, z = CFrame.new(Vector3.new(9, 0, 0), mousePos):ToOrientation()

		-- Define rotation offset (adjust these values as needed)
		local offsetRotation = Vector3.new(0, 75, 0) -- Example offset

		-- Apply the offset to the rotation
		local finalRotation = Vector3.new(
			(x * 25) + offsetRotation.X, 
			-(100 - ((y * 125) / 5)) + offsetRotation.Y, 
			z + offsetRotation.Z
		)

		-- Tween the rotation with the offset applied
		TweenService:Create(
			v.PrimaryPart,
			TweenInfo.new(0.4, Enum.EasingStyle.Quint),
			{ Orientation = finalRotation }
		):Play()
	end
end)

It seems to work fine based on the video?

#3

the buttons and all of their parts are supposed to move together, but only the primary parts are moving

#4

If they are welded and unanchored then I don’t know what would cause it aside from maybe viewport frames not simulating physics. I’m not sure if they do or not because I never use them.

#5

Maybe try a world model? That might work.

maybe its because tween ignores physics

OP, try using AlignOrientation if you’d still wanna go with the physics way

#8

but if you’d still go with the tween way…

instead of tweening the primary part, try tweening a CFrameValue and whenever the value of the cframevalue changes, apply the value of cframevalue to the frame of the module using PivotTo

also use CFrame.lookAt() for this (though you might need to adjust cuz i didnt really consider some parts of ur code)

basic/main idea:

local CFrameValue = model.CFrameValue
TweenService:Create(CFrameValue, TweenInfo.new(0.4, Enum.EasingStyle.Quint), {Value = CFrame.lookAt(model:GetPivot().Position, mousePos)}):Play()

-- in a separate section of the code
CFrameValue:GetPropertyChangedSignal("Value"):Connect(function()
	model:PivotTo(CFrameValue.Value)
end)

I have never worked with CFrameValue before but i will try to make it work, i will mark this as a solution if it works

#10

i just tried using a WorldModel but its still the same issue

#11

The reason this happens is because you need to Tween the CFrame and not the Position / Orientation since they are not replicated and won’t work with welds.

Try something like this maybe:

local finalRotation = CFrame.Angles(
	(x * 25) + offsetRotation.X, 
	-(100 - ((y * 125) / 5)) + offsetRotation.Y, 
	z + offsetRotation.Z
)

TweenService:Create(
	v.PrimaryPart,
	TweenInfo.new(0.4, Enum.EasingStyle.Quint),
	{ CFrame = CFrame.new(v.PrimaryPart.Position) * finalRotation }
):Play()

There is no reason to use a CFrameValue here, but if you feel like that’s easier for you then feel free to do that

I provided the code that i think should fix your issue, if not please tell me

#13

oh, i didin’t know that Postition and Orientation don’t work with welds, thank you for letting me know.
Also i have already rewritten the code so that it uses :Lerp() and model:PivotTo() instead.

I will keep this in mind when i try to tween a model next time!
