--File:Local Script in Script /\
local CurrentCamera = game.Workspace.CurrentCamera -- Get Camera
local Part = Instance.new('Part') --Do not parent yet

--Make the part stuff...
Part.Name = 'Invisible Part'
Part.Position = game.Workspace:WaitForChild(script.Parent.Parent.Name).Head.Position + Vector3.new(0,2,0)
Part.Size = Vector3.new(2,2,2)

wait(2) -- A little timeout eh?
Part.Parent = CurrentCamera --Parent to Current Camera to become an official Local Part
