How can detect when a player puts the joystick up on mobile?

Im trying to make a cloud, and I have the computer working, but I want to know how I would make it work for players. For now, I just want to know when player puts his joystick up on mobile. Any help on this?

Local Script

game:GetService("UserInputService").InputBegan:Connect(function(inputObject, gameProcessedEvent)
	if inputObject.KeyCode == Enum.KeyCode.Up or inputObject.KeyCode == Enum.KeyCode.W or inputObject.KeyCode == Enum.KeyCode.DPadUp or inputObject.KeyCode == Enum.KeyCode.Thumbstick1 then
		print("Cloud Movement")
end
end)

The above script would actually work on all devices (mobile, pc, console, tablet)

The Enum.KeyCode that relates to the Mobile device is the Enum.KeyCode.DPadUp in this case.

EDIT: Try using this:

local player = game.Players.LocalPlayer
repeat wait() until player.Character ~= nil and workspace:FindFirstChild(player.Name) ~= nil
player.Character.Humanoid:GetPropertyChangedSignal("MoveDirection"):Connect(function()
	if player.Character.Humanoid.MoveDirection ~= Vector3.new(0, 0, 0) then
		print("Cloud Movement 2")
	end
end)

There's apparently no Enum.KeyCode for the Mobile Phones yet, so MoveDirection will have to suffice to determine the movement.
