Can anyone figure out how to add Debounce to uis.inputended?

****MY big ugly code dont hate ;(

local req = 0
local LCV  --Lets make this nill
local deb = false 

uis.InputBegan:connect(function(input, GPE)
	if GPE then return end
	if input.KeyCode == Enum.KeyCode.E then
		if not deb then
		deb = true
		req = 0
        LCV = true
		
		local human = char.Humanoid
		ani.AnimationId = "http://www.roblox.com/asset?id=387149840"
			if human then
				local load = human:LoadAnimation(ani)
				if load then
				load:Play()
			end
		end	
	
	
		while LCV do
		wait(1)
		req = req + 1
		print 'added 1'
		end
		
	
		end
		
	wait(2)
	deb = false
	print 'cooled'
		end
end)



uis.InputEnded:connect(function(input)--Aftet button was released
	if input.KeyCode == Enum.KeyCode.E then
        LCV = false
		print(req)
		ani.AnimationId = "http://www.roblox.com/asset?id=387152305"

		local hu = char.Humanoid
		if hu then
			local load = hu:LoadAnimation(ani)
			if load then
			load:Play()
			
			wait(2)
			load:Stop()
			end
		end	
	end
end)

Declare the debounce variable outside the function and change it within the function. That way, the variable isn't overridden every time you run the function.

local debounce = false --look at me! I'm outside the function!

function doStuff()
	if debounce then --return nothing and exit the function if debounce is true
		return
	else
		debounce = true
		--do stuff!
		debounce = false
	end
end
