Gate script question, how do I put a debounce in it?

What I want to do is this: Put a debounce in the script. SO then if you click the button the gate will slide thorough. But if you click it again it will slide back. But you have to wait a couple seconds for it to slide back. I am also toying around with it to see if I can make it not make the gate go too far if it is repetedly pressed. I would love it if someone would help me!

DoorSystem = script.Parent 
Door = DoorSystem.Door1 
DoorPad = DoorSystem.Open.ClickDetector
local padPressed = false

function Slide()
	if not padPressed then
		padPressed = true
		for i = 1, 500 do
    		Door.CFrame = Door.CFrame + Vector3.new(0, 0, 0.1)
     		wait()
		end
	end
end

DoorPad.MouseClick:connect(Slide)

This isn't quite a standard debounce.

Basically, we have to make new button presses interrupt old ones. Instead of doing the loop in the event, though, it really is easier to make the event just write the direction, rather than actually repeatedly act on it:

DoorSystem = script.Parent 
Door = DoorSystem.Door1 
DoorPad = DoorSystem.Open.ClickDetector

home = Door.CFrame -- Where the door STARTS
open = 0 -- How far (in studs) the door is open

direction = 0
speed = 0.3 -- studs/second

function Slide()
	-- Flip direction (turn around)
	if direction <= 0 then
		direction = 1
	else
		direction = -1
	end
end

DoorPad.MouseClick:connect(Slide)


while true do 
	open = open + direction * speed * wait()
	open = math.max(0, open) -- Not a negative opening
	open = math.min(50, open) -- At most 50 studs open
	Door.CFrame = home + Vector3.new(0, 0, open)
end

This won't close on its own, though.

A partial solution is this:

function Slide()
	-- Flip direction (turn around)
	if direction <= 0 then
		direction = 1
		wait(5)
		direction = -1
	else
		direction = -1
	end
end

The problem is input like this:

• 0s : Click (starts opening)
• 3s : Click (starts closing)
• 4s : Click (starts opening again)
• 5s : wait(5) from first click just fired, so door closes

That interruption in the last moment is the problem. Basically, we need to measure if there has been another click in the last 5 seconds:

lastClick = 0

function Slide()
	-- Flip direction (turn around)
	lastClick = tick()
	now = tick()
	if direction <= 0 then
		direction = 1
		wait(5)
		if lastClick <= now then
			direction = -1
		end
	else
		direction = -1
	end
end
