Hi, how do i make this script not function once the part was touched once? here is my code:

local debounce = 3
local bin = true

script.Parent.Touched:Connect(function(hit)
	local Humanoid = hit.Parent:FindFirstChild("Humanoid")
	if Humanoid and bin then
		bin = false
		local HD = Humanoid:GetAppliedDescription()
		HD.HeadScale = HD.HeadScale * .2
		HD.DepthScale = HD.DepthScale * .2
		HD.WidthScale = HD.WidthScale * .2
		HD.HeightScale = HD.HeightScale * .2
		Humanoid:ApplyDescription(HD)
		wait(debounce)
		bin = true
	end
end)

You can try using the :Disconnect() function:

local Touch
Touch = script.Parent.Touched:Connect(function(hit)
	local Humanoid = hit.Parent:FindFirstChild("Humanoid")
	if Humanoid then
		local HD = Humanoid:GetAppliedDescription()
		HD.HeadScale = HD.HeadScale * .2
		HD.DepthScale = HD.DepthScale * .2
		HD.WidthScale = HD.WidthScale * .2
		HD.HeightScale = HD.HeightScale * .2
		Humanoid:ApplyDescription(HD)
		Touch:Disconnect() -- Disconnect the function, so it won't fire again
	end
end)

You can use the :Disconnect() function like TOP_Crundee123 said, or you could do it without using a connection at all. By calling :Wait() on an event, the code will yield until that event is fired. So here is an alternate solution that will also work.

script.Parent.Touched:Wait()
local Humanoid = hit.Parent:FindFirstChild("Humanoid")
if Humanoid and bin then
	bin = false
	local HD = Humanoid:GetAppliedDescription()
	HD.HeadScale = HD.HeadScale * .2
	HD.DepthScale = HD.DepthScale * .2
	HD.WidthScale = HD.WidthScale * .2
	HD.HeightScale = HD.HeightScale * .2
	Humanoid:ApplyDescription(HD)
	wait(debounce)
	bin = true
end

Edit: Actually I don’t know how you would use the hit parameter in this case.
