How do i make something if you doubletap a key

#1

I am making a main menu and i want to make it reopen after doubletapping a key.

What is the issue? It prints it always when you press the key not double tapping.

UIS.InputBegan:Connect(function(input, gameProcessed)
	if input.KeyCode == Enum.KeyCode.M then 
		if not gameProcessed then
	       	if not lastMPress then
				lastMPress = true
				wait(0.25)
				lastMPress = false
			else
				print("doubletapped")
			end
		end
	end	
end)

Why won't this animation stop?

Btw, gameProcessed if statement belongs first to be checked.

Also, this prints double tap everytime the button is pressed in a 0.25 second time frame rather than double tap, you need to reset lastMPress on the second tap.

I have a double press key for my main menu. The idea behind determining when someone pressed a key twice is to determine when they last pressed the key and then act upon that value. This typically should, to retain the spirit of the action, be held in a small time window.

local EXIT_THRESHOLD = 0.25

local lastMPress = 0

UIS.InputBegan:Connect(function (inputObject, gameProcessedEvent)
    if gameProcessedEvent then return end

    if inputObject.KeyCode == Enum.KeyCode.M then
        local currentTime = tick()
        if currentTime - lastMPress <= EXIT_THRESHOLD then
            doublePressedMAction()
        else
            lastMPress = currentTime
        end
    end
end)

Detect a key that is double tapped
#4 
local Sens = 0.12
local LastPressed = nil
game:GetService("UserInputService").InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.M then
		local Trig = false
		if LastPressed ~= nil then
			if tick() - LastPressed <= Sens then
				print("Open Menu")
				Trig = true
			end
		end
		if not Trig then
			LastPressed = tick()
		end
	end 
end)
