Key Inputs To Control Vector3?

I'm making a script that uses WASD to control the path of a tornado.

This is my keydown script:

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

mouse.KeyDown:connect(function(key)
    if key == "a" then
	game.Workspace.Direction.Value = "West"
	elseif key == "w" then
	game.Workspace.Direction.Value = "North"
	elseif key == "s" then
	game.Workspace.Direction.Value = "South"
	elseif key == "d" then
	game.Workspace.Direction.Value = "East"
end
   
end)

and this is my tornado animation script:

while true do
	torx = script.Parent.Position.X
	torz = script.Parent.Position.Z
if game.Workspace.Direction.Value == "West" then
	x = torx-1
	script.Parent.Position = Vector3.new(x,96.5,torz)
	elseif game.Workspace.Direction.Value == "East" then
	x = torx+1
	script.Parent.Position = Vector3.new(x,96.5,torz)
	elseif game.Workspace.Direction.Value == "North" then
	z = torz-1
	script.Parent.Position = Vector3.new(torx,96.5,z)
	elseif game.Workspace.Direction.Value == "South" then
	z = torz+1
	script.Parent.Position = Vector3.new(torx,96.5,z)
else
	print"nuffin"
end
wait(1)
end

When I press the keys, the Direction value is telling me one of the 4 directions, but the tornado doesn't move. Note that the script keeps printing "nuffin", so it doesn't see the value change.

What can be done to fix this? Thanks!

Hi! As you may know, because of FilteringEnabled, the client can't speak with the server directly.

If both scripts are local, ignore this, it is a wrong explanation.

If your LocalScript is modifying the value, but your server-side script can't see it, you might want to use remote events to change the value.
