Controller Support Question(Limiting thumbstick to X movement only) How to?

I want to restrict this to X movement alone. I just started using newer features of Roblox and gamepads are harder than I thought. I'm making a Side-scrolling fighting game like Mortal Kombat.

game:GetService("UserInputService").InputChanged:connect(function(input, processed)
	if input.UserInputType == Enum.UserInputType.Gamepad1 then
		if input.KeyCode == Enum.KeyCode.Thumbstick1 then
			character.Humanoid:Move(Vector3.new(input.Position.X, 0, -input.Position.Y), true)
		end
	end
end)
