How do I make a part follow a player?

Like, when you get a zombie that follows you. Except it doesn't kill you. I'm not sure of a script for this, as I am new with scripting. I have tried a few but deleted them. This is th emost recent one, that still doesn't work. local larm = script.Parent:FindFirstChild("Left Arm") local rarm = script.Parent:FindFirstChild("Right Arm")

function findNearestTorso(pos) local list = game.Workspace:children() local torso = nil local dist = 1000 local temp = nil local human = nil local temp2 = nil for x = 1, #list do temp2 = list[x] if (temp2.className == "Model") and (temp2 ~= script.Parent) then temp = temp2:findFirstChild("Right Arm") human = temp2:findFirstChild("Humanoid") if (temp ~= nil) and (human ~= nil) and (human.Health > 0) then if (temp.Position - pos).magnitude < dist then torso = temp dist = (temp.Position - pos).magnitude end end end end return torso end

while true do wait(math.random(1,5)) local target = findNearestTorso(script.Parent.Torso.Position) if target ~= nil then script.Parent.Humanoid:MoveTo(target.Position, target) end

Thank you, and I hope you can help.
