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

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)
