Vid link: https://streamable.com/cejhwu script:

local bar = script.Parent.Bar
local cd = script.Parent.Bar.ClickDetector
local ts = game:GetService("TweenService")
local ti = TweenInfo.new(
    0.3,    
    Enum.EasingStyle.Linear,
    Enum.EasingDirection.Out,
    0,
    false,
    0
)

local pulleddown = script.Parent.pulled.Value
local Positions = script.Parent.Positions
local uppos = {CFrame = CFrame.new(Positions.uppos.Position)}
local downpos = {CFrame = CFrame.new(Positions.downpos.Position)}
local up = ts:Create(bar,ti,uppos)
local down = ts:Create(bar,ti,downpos)
local re = game.ReplicatedStorage.lockdown
local function pulled()
    if pulleddown == false
    then 
        down:Play()
        pulleddown = true
        re:FireAllClients()
    elseif pulleddown == true then
        up:Play()
        pulleddown = false
end
end
cd.MouseClick:Connect(pulled)
