How would I add debounce to this click detector script?

It us fairly easy to make a debounce:

clickDetector = game.workspace.Box.top.ClickDetector

loal debounce = true

function onMouseClick() 
if debounce then
debounce = false
game.Workspace.Box.bottom.Transparency = 0 game.Workspace.Box.top.Transparency = 1

            local num = math.random(1,5)

            if num == 1 then

                print("1")

            elseif num == 2 then

                print("2")

            elseif num == 3 then

                print("3")

            elseif num == 4 then

                print("4")

            elseif num == 5 then

                print("5")

        end
    wait(3)
    game.Workspace.Box.bottom.Transparency = 1
    game.Workspace.Box.top.Transparency = 0
    debounce = true
    end
end clickDetector.MouseClick:connect(onMouseClick)
