How do you get a enemy NPC to lock onto (and follow) a player?

This is the revised version of my previous question. -- The main problem with the code below is that the battledroid (the enemy npc in my game) will not lock onto the player, but will lock onto a "drooling zombie" (test npc). There's a line of code that checks if a humanoid is there and if it isn't it'll check for a zombie. What can I do to make it so the droid (enemy npc) will lock onto the player? I'll give the code as well as the link to the game below.

01local larm = script.Parent:FindFirstChild("Left Arm")
02local rarm = script.Parent:FindFirstChild("Right Arm")
03 
04function findNearestTorso(pos)
05    local list = game.Workspace:children()
06    local torso = nil
07    local dist = 500
08    local temp = nil
09    local human = nil
10    local temp2 = nil
11    for x = 1, #list do
12        temp2 = list[x]
13        if (temp2.className == "Model") and (temp2 ~= script.Parent) then
14            temp = temp2:findFirstChild("Right Arm")
15            human = temp2:findFirstChild("Humanoid")
16            if (temp ~= nil) and (human ~= nil) and (human.Health > 0) then
17                if (temp.Position - pos).magnitude < dist then
18                    torso = temp
19                    dist = (temp.Position - pos).magnitude
20                end
21            end
22        end
23    end
24    return torso
25end

27human = script.Parent:findFirstChild("Humanoid")
28if human == nil then human = script.Parent:findFirstChild("Zombie") end
29 
30while true do
31    wait(1)
32    local target = findNearestTorso(script.Parent.Torso.Position)
33    if target ~= nil then
34        human:MoveTo(target.Position, target)
35        human.TargetPoint = target.Position
36    end

Try this

01local npc = script.Parent
02local hrpOfNPC = npc:WaitForChild("HumanoidRootPart")
03 
04local plrsHit = {}
05 
06local maxDistance = math.huge
07 
08 
09npc.Humanoid.Touched:Connect(function(touch)
10 
11    if game.Players:GetPlayerFromCharacter(touch.Parent) and not plrsHit[game.Players:GetPlayerFromCharacter(touch.Parent)] then
12 
13        plrsHit[game.Players:GetPlayerFromCharacter(touch.Parent)] = true
14 
15        touch.Parent.Humanoid:TakeDamage(20)
16 
17        wait(1)
18 
19        plrsHit[game.Players:GetPlayerFromCharacter(touch.Parent)] = false 
20    end
21end)
22 
23 
24while wait() do
25 
26    local plrs = game.Players:GetPlayers()
27 
28    local closestHRP
29 
30    for i, plr in pairs(plrs) do
31 
32        if plr.Character and plr.Character:FindFirstChild("HumanoidRootPart") and plr.Character.Humanoid.Health > 0 then
33 
34            local hrp = plr.Character.HumanoidRootPart
35 
36            local distanceBetween = (hrpOfNPC.Position - hrp.Position).Magnitude
37 
38 
39            if not closestHRP then closestHRP = hrp end
40 
41            if (hrpOfNPC.Position - closestHRP.Position).Magnitude > distanceBetween then
42 
43                closestHRP = hrp
44 
45            end
46        end
47    end
48 
49    if closestHRP and (hrpOfNPC.Position - closestHRP.Position).Magnitude <= maxDistance then npc.Humanoid:MoveTo(closestHRP.Position) end
50end
