How can I make a move trigger?

How would I make a trigger that moves an object? I am making a horror game and I want it so once the player reaches a certain point a shadow moves across the road in front of them.

Easy way to do this is with a .Touched event on a part.

Script in ServerScriptService

local trigger = workspace:FindFirstChild("TriggerBlock");
local spooky = workspace:FindFirstChild("Spooky");
local start, stop = workspace:FindFirstChild("Start"), workspace:FindFirstChild("Stop");


trigger.Touched:Connect(function(hit)
  if hit.Parent:FindFirstChild("Humanoid") then
    spooky.CFrame = start.CFrame;
    game:GetService("TweenService"):Create(spooky, TweenInfo.new(1), {CFrame = stop.CFrame}):Play(); --The one represents one second, or how long it will take "spooky" to run across the hall, CFrame = stop.CFrame will make spooky run from start.CFrame to stop.CFrame in 1 second.
  end;
end);
