Hi, I’m trying to create a navigation sphere for my rocket building game.

The problem:


The blue ball is supposed to rotate with the blue ring:

local RunService = game:GetService("RunService")
local Workspace = game:GetService("Workspace")

local Model = Workspace.Test
local Root = Model.Root

local BlueRing = Model.Blue
local YellowRing = Model.Yellow
local BluePointer = Model.BluePointer
local YellowPointer = Model.YellowPointer

local R = 2

local Amount = 0

local function Update()
	
	Amount = Amount + 1
	
	YellowPointer.CFrame = CFrame.new(Root.Position) * CFrame.Angles(0, math.rad(Amount), 0) * CFrame.new(0, 0, R)
	
	BlueRing.CFrame = CFrame.new(Root.Position, YellowPointer.Position) * CFrame.Angles(0, 0, math.rad(90))
	BluePointer.CFrame = CFrame.new(Root.Position) * CFrame.Angles(0, 0,  math.rad(Amount)) * CFrame.new(0, R, 0)
	
	local GyroCFrame = CFrame.new(Root.Position, BluePointer.Position)
	
end

You could weld the blue ball to the ring.
