How to do combo-keys, e.g. R3 + X on roblox?

So someone press R3 + X on their XBOX to perform an action in a game.

there might be a more efficient way but this is what i came up with

local uis = game:GetService("UserInputService")

local xHeld = false
local r3Held = false

uis.InputBegan:Connect(function(i, gpe)
	if gpe then return end
	
	if i.UserInputType == Enum.UserInputType.Gamepad1 then
		if i.KeyCode == Enum.KeyCode.ButtonX then
			xHeld = true
		end
	end
end)

uis.InputEnded:Connect(function(i, gpe)
	if gpe then return end

	if i.UserInputType == Enum.UserInputType.Gamepad1 then
		if i.KeyCode == Enum.KeyCode.ButtonX then
			xHeld = false
		end
	end
end)

uis.InputBegan:Connect(function(i, gpe)
	if gpe then return end

	if i.UserInputType == Enum.UserInputType.Gamepad1 then
		if i.KeyCode == Enum.KeyCode.Thumbstick2 then
			r3Held = true
		end
	end
end)

uis.InputEnded:Connect(function(i, gpe)
	if gpe then return end

	if i.UserInputType == Enum.UserInputType.Gamepad1 then
		if i.KeyCode == Enum.KeyCode.Thumbstick2 then
			r3Held = false
		end
	end
end)

local attacking = false

local function attack()
	attacking = true
	-- do attack
	delay(3, function()
		-- 3 second delay till can attack again
		attacking = false
	end)
end

game:GetService("RunService").RenderStepped:Connect(function()
	
	if attacking then return end
	
	if r3Held and xHeld then
		attack()
	end
end)

A better alternative to tracking the state of every button on every frame is to just check the state of a specific set of buttons when one of them is pressed. For example, here’s a sample that lets you easily add more combinations as you need:

--!strict

local UserInputService = game:GetService("UserInputService")

type Callback = () -> nil

local function onCombo1Pressed()
	print("Combo 1 pressed")
end

local inputCombinations: { [Callback]: { Enum.KeyCode }} = {
	[onCombo1Pressed] = {
		Enum.KeyCode.ButtonX,
		Enum.KeyCode.ButtonR3,
	},
}

local function checkAreAllKeysPressed(keys: { Enum.KeyCode }): boolean
	for _, key in keys do
		if not UserInputService:IsKeyDown(key) then
			return false
		end
	end
	return true
end

local function getPressedCombinationsContainingKey(keyCode: Enum.KeyCode): { Callback }
	local pressedCombinationsContainingKey = {}
	for callback, keyCodes in inputCombinations do
		if not table.find(keyCodes, keyCode) then
			continue
		end
		if checkAreAllKeysPressed(keyCodes) then
			table.insert(pressedCombinationsContainingKey, callback)
		end
	end
	return pressedCombinationsContainingKey
end

UserInputService.InputBegan:Connect(function(inputObject: InputObject, isProcessed: boolean)
	if isProcessed then
		return
	end

	if inputObject.UserInputType == Enum.UserInputType.Gamepad1 then
		local pressedCombinationsContainingKey = getPressedCombinationsContainingKey(inputObject.KeyCode)
		for _, callback in pressedCombinationsContainingKey do
			callback()
		end
	end
end)
