Detect a key that is double tapped

I want that if you double tap "D"or “A”, it will dash but I can’t find how to detect double tap

I have tried a lot of way to obtain this but i cant

It seems like this post may answer your question:

How do i make something if you doubletap a key

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 cu…

As stated by @SeargentAUS , there is already a post answering this question. However, I have written a script tailored to your specific use case:

local UIS = game:GetService("UserInputService")

local leftDashKey = Enum.KeyCode.A
local rightDashKey = Enum.KeyCode.D

local maxDelay = 0.25
local t1 = 0
local t2 = 0

UIS.InputBegan:Connect(function (input, gp)
	if gp then return end

	if input.KeyCode == leftDashKey then
		if tick() - t1 <= maxDelay then
			print("dash left")
		else
			t1 = tick()
		end
	end
	
	if input.KeyCode == rightDashKey then
		if tick() - t2 <= maxDelay then
			print("dash right")
		else
			t2 = tick()
		end
	end
	
end)

This code simply creates two congruent systems that compare the elapsed time since the previous key press. If the current key is equal to the previous key and the time since the previous input doesn’t exceed .25 seconds then the script fires and prints to log.
Hope this helps!
