Tweening vector3 negatively tweens all 3 axis

#1

Whenever i attempt to tween vector3 on one axis negatively, for some reason the other 2 axis also tween as well. (See attached video)

Whenever i tween positively this does not happen. Any help appreciated.

local TweenService = game:GetService("TweenService")
local ti = TweenInfo.new(0.15, Enum.EasingStyle.Back, Enum.EasingDirection.Out)
local Goal = {Rotation = Vector3.new(0,120,0)}
local Goal2 = {Rotation = Vector3.new(0,90,0)}
local Goal3 = {Rotation = Vector3.new(0,60,0)}
local ScaleGoal = {Scale = 0.9}
local ScaleGoal2 = {Scale = 1.1}
local ScaleGoal3 = {Scale = 1}

local FrameTrigger = require(game:GetService("ReplicatedStorage"):WaitForChild("Packages"):WaitForChild("FrameTrigger")) 

local Buttons = script.Parent:WaitForChild("Frame")

function convertAbsoluteToScale(frame): UDim2
	local container = frame.Parent

	local containerAbsPos = container.AbsolutePosition
	local containerAbsSize = container.AbsoluteSize

	local frameAbsPos = frame.AbsolutePosition

	local frameRelativePos = frameAbsPos - containerAbsPos

	return UDim2.fromScale(frameRelativePos.X / containerAbsSize.X, frameRelativePos.Y / containerAbsSize.Y)
end

local reversable = false

for i,v in Buttons:GetChildren() do
	if v:IsA("Frame") then
		
		local Click: TextButton = v:WaitForChild("Click")
		
		
		local Tween = TweenService:Create(v:WaitForChild("ViewportFrame"):WaitForChild("Part"), ti, Goal)
		local Tween2 = TweenService:Create(v:WaitForChild("ViewportFrame"):WaitForChild("Part"), ti, Goal2)
		local Tween3 = TweenService:Create(v:WaitForChild("ViewportFrame"):WaitForChild("Part"), ti, Goal3)
		local ScaleTween2 = TweenService:Create(v.UIScale, ti, ScaleGoal2)
		local ScaleTween = TweenService:Create(v.UIScale, ti, ScaleGoal)
		local ScaleTween3 = TweenService:Create(v.UIScale, ti, ScaleGoal3)
		
		local Decal: Decal = v:WaitForChild("ViewportFrame"):WaitForChild("Part"):WaitForChild("Decal")
		local CachedColor = Color3.fromRGB(255, 255, 255)
		
		Click.MouseEnter:Connect(function()
			
			if convertAbsoluteToScale(v).X.Scale > 0.45 then
				Tween3:Play()
			else
				Tween:Play()
			end
			
		end)
		Click.MouseLeave:Connect(function()
			Tween2:Play()
			ScaleTween3:Play()
			Decal.Color3 = CachedColor
		end)
		
		Click.MouseButton1Down:Connect(function()
			ScaleTween:Play()
			FrameTrigger.OpenFrame(v.Name)
			Decal.Color3 = Color3.new(Decal.Color3.R/2, Decal.Color3.G/2, Decal.Color3.B/2)
		end)
		Click.MouseButton1Up:Connect(function()
			Decal.Color3 = CachedColor
			ScaleTween3:Play()
		end)
		
	end

Change this:

to this:

local Goal = {Orientation = Vector3.new(0,120,0)}
local Goal2 = {Orientation = Vector3.new(0,90,0)}
local Goal3 = {Orientation = Vector3.new(0,60,0)}

This might work, since you’re only rotating about Y. The older Rotation property has XYZ order, not YXZ that’s more recently used, and it looks like the Rotation values aren’t tweening correctly, from some internal Euler conversion issue no doubt.

If even this causes problems, a sure way to fix it would be to just tween the Y rotation value manually, like tweening a number value object, and using a script to set the part CFrame yourself, from CFrame.fromAxisAngle( Vector3.yAxis, math.rad(angleInDeg)). You’d have to bind another listener to ValueObject.Changed for each part. Hopefully you won’t have to do that though.
