How to make an arrow, that shows you the next button (Tycoon)

Help and Feedback Scripting Support

Hello! I want to make an arrow (beam), that shows you the next button (or e.g. if there are 2 buttons, one is randomly chosen) in my Tycoon-System.

This is what I got so far (the script is in StarterCharacterScripts):

local plr = game.Players.LocalPlayer
local char = script.Parent

local partsToBeam = {}

local function pathToPart(beam, attachment0, part)
	local attachment1 = part:FindFirstChildOfClass("Attachment")
	if attachment1 then
		beam.Attachment0 = attachment0
		beam.Attachment1 = attachment1
	else
		warn("You forgot to add an attachment (--> "..part.Name..")")
	end
end

plr.PlayerGui.MainGui.Bar.ShowArrow.TextButton.MouseButton1Click:Connect(function()
	local humanoidRootPart = char:WaitForChild("HumanoidRootPart")
	local attachment0 = humanoidRootPart:WaitForChild("RootRigAttachment")

	if plr.PlayerGui.MainGui.Bar.ShowArrow.BackgroundColor3 == Color3.fromRGB(216, 216, 216) then
		local beam = script:WaitForChild("Beam"):Clone()

		pathToPart(beam, attachment0, workspace:WaitForChild("SpawnLocation"))
		beam.Parent = char
		plr.PlayerGui.MainGui.Bar.ShowArrow.BackgroundColor3 = Color3.fromRGB(0, 255, 0)
	else
		char.Beam:Destroy()
		plr.PlayerGui.MainGui.Bar.ShowArrow.BackgroundColor3 = Color3.fromRGB(216, 216, 216)
	end
end)

→ The post that I based myself on (original post): How is this "Follow the arrows" system made?

This is, how to get all buttons in the Tycoon:

for _, allTycoons in pairs(workspace.Tycoons:GetChildren()) do
	if allTycoons.Values.PlayerName.Value == plr.Name and allTycoons.Values.Owned.Value == true then
		for _, allButtons in pairs(allTycoons.Buttons:GetChildren()) do

        end
	end
end

Ty for any answers!
