How do you make it so you cant spam a click detector?

my shower keeps turning off and off after spamming it with 10 clicks

You would add a debounce so that there was a cooldown between clicks:

local debounce = true
local cooldown = 5 --change to seconds between clicks
script.Parent.ClickDetector.MouseClick:Connect(function()
	if debounce then
		debounce = false
		--do shower script
		wait(cooldown)
		debounce = true
	end
end)
