Creating a multi-key keybind

Help and Feedback Scripting Support
#1

Hello!

I’m currently working on revamping my ban system/administrator panel. To open it, I want to have a keybind that requires 2 or 3 keys to be pressed. I tried looking up keybinds for lua, and I only found single-key keybinds, not multi-key, which I already know how to do. Where do I start with this? The closest thing I’ve found was this, however I don’t know how to make it apply to my specific scenario.

You would really just keep track of the keys which are being held down.

Example:

local UIS = game:GetService("UserInputService")
local AltDown = false

UIS.InputBegan:Connect(function(input, gameProcessedEvent)
	if gameProcessedEvent then return end -- if you're typing in a e.g. a textbox, the next lines will be ignored

	if input.KeyCode == Enum.KeyCode.LeftAlt then
		AltDown = true
	elseif input.KeyCode == Enum.KeyCode.D then
		if not AltDown then return end -- if alt is not being held down, then don't continue
		MyFunction() -- fire the function which does what you want it to do
	end
end)

UIS.InputEnded:Connect(function(input, gameProcessedEvent)
	if input.KeyCode == Enum.KeyCode.LeftAlt then
		AltDown = false
	end
end)

Extra: a tip I can give you for KeyCodes is to type “Enum.KeyCode.” then a bunch of KeyCodes will appear in a list and you can then use the arrows to scroll through them to find the KeyCode that you want if you don’t remember it.

You Could have an If statement ReQuire Both Keys to be true:

local UIS = game:GetService("UserInputService")

local Key1 = --the first key--
local Key2 = --the sceond key--

if Key1 == true and Key2 == true then
     ---Do Script or function
else
     Key1 = false
     Key2 = false
end


UIS.InputEnded:Connect(function(input, gameProcessedEvent)
	if input.KeyCode == Enum.KeyCode.One then             ------------"1" button
		Key1 = True
	end
end)

UIS.InputEnded:Connect(function(input, gameProcessedEvent)
	if input.KeyCode == Enum.KeyCode.Two then            -------------"2" button
		Key2 = True
	end
end)

You could use UserInputService:IsKeyDown to check whether the keys are down
Example(using Alt + M):

local UIS = game:GetService("UserInputService")

UIS.InputBegan:Connect(function(input)

if (input.KeyCode == Enum.KeyCode.M and UIS:IsKeyDown(Enum.KeyCode.Alt)) or (input.KeyCode == Enum.KeyCode.Alt and UIS:IsKeyDown(Enum.KeyCode.M)) then

-- run function

end

end)

It is a little clunky but it works.

However it is sometimes recommended to use ContextActionService.
