NPC isn't facing me when I move?

So I have an NPC that's supposed to follow the player. I got it to do that, but it doesn't face the player when it moves and it's kind of just blank. Here's what it does I recycled this script from another npc that I made and it seems to work perfectly. I only switched models because it couldn't support animations. Zombie Any help with this? Here's the script

```

local function gethumanoids()

local humanpos = {}

for a, b in pairs(game.Workspace:GetChildren()) do

if b:FindFirstChild("Humanoid") and b ~= script.Parent then

local name = b.Name

if game.Players:FindFirstChild(name) then

table.insert(humanpos,(script.Parent.HumanoidRootPart.Position - b.HumanoidRootPart.Position).magnitude)

end

end

end

table.sort(humanpos)

for a, b in pairs(humanpos) do

if a ~= 1 then

table.remove(humanpos.a)

end

end

for a, b in pairs(game.Workspace:GetChildren()) do

if b:FindFirstChild("Humanoid") and b ~= script.Parent then

local name = b.Name

if game.Players:FindFirstChild(name) then

if (script.Parent.HumanoidRootPart.Position - b.HumanoidRootPart.Position).magnitude == humanpos[1] then

return b

end

end

end

end

end

while true do

local path = game:GetService("PathfindingService"):CreatePath()

path:ComputeAsync(script.Parent.HumanoidRootPart.Position, gethumanoids().HumanoidRootPart.Position)

local points = path:GetWaypoints()

script.Parent.AttackingPlayer.Value = gethumanoids().Name

script.Parent.Parent.Points:ClearAllChildren()

for a, b in pairs(points) do

part = Instance.new("Part")

part.CanCollide = false

part.Size = Vector3.new(1,1,1)

part.Position = b.Position

part.Anchored = true

part.Transparency = 0

part.Parent = script.Parent.Parent.Points

end

if path.Status == Enum.PathStatus.Success then

for a, b in pairs(points) do

script.Parent.Humanoid:MoveTo(part.Position)

if b.Action == Enum.PathWaypointAction.Jump then

script.Parent.Humanoid.Jump = true

end

end

end

end```
