The zombie NPC won't do anything, even though I want It to protect you (?)

Hello!

Im making a zombie staff that summons a zombie from ReplicatedStorage that targets other people besides you, currently, It does nothing

(Also, there Is a StringValue Inside of the zombie, Its used to get the owner of the zombie staff)

No errors appeared In

Script (Zombie):

local NPC = script.Parent
local Pathfinding = game:GetService("PathfindingService")
local Creator = script.Parent.Creator
function GetPlayerNames()
	local players = game:GetService('Players'):GetChildren()
	local name = nil
	for _, v in pairs(players) do
		if v:IsA'Player' then
			name = tostring(v.Name)
		end
	end
	return name
end
function GetTorso(part)
	local chars = game.Workspace:GetChildren()
	local torso = nil
	for _, v in pairs(chars) do
		if v:IsA'Model' and v ~= script.Parent and v.Name == GetPlayerNames() and not v.Name == Creator.Value then
			local charRoot = v:FindFirstChild'HumanoidRootPart'
			if (charRoot.Position - part).magnitude < SearchDistance then
				torso = charRoot
			end
		end
	end
	return torso
end
while task.wait() do
	local path = Pathfinding:CreatePath()

	local NPC_Torso
	if NPC:FindFirstChild("UpperTorso") then
		NPC_Torso = NPC.UpperTorso
	else
		NPC_Torso = NPC.Torso
	end
	if GetTorso(NPC_Torso) == nil then
		return
	end
	-- Line 30
	path:ComputeAsync(GetTorso(NPC_Torso).Position, GetTorso(NPC_Torso).Position)--its gonna make a radius around the npc torso position to check for players

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

		local Positions = path:GetWaypoints()

		for i,v in pairs(Positions) do

			local position = Instance.new("Part")

			position.Parent = game.Workspace

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

			position.Position = v.Position

			position.Transparency = 1

			NPC.Humanoid:MoveTo(position.Position)

			NPC.Humanoid.MoveToFinished:Wait(2)

			position:Destroy()

		end

	end
end

Summoning script:

local tool = script.Parent
local debounce = false

tool.Activated:Connect(function()
	if not debounce then
		debounce = true
		local Zombie = game.ReplicatedStorage.Zombie:Clone()
		Zombie.Parent = game.Workspace
		Zombie.Torso.CFrame = tool.Handle.CFrame
		if Zombie:FindFirstChild("Creator") then
			Zombie:FindFirstChild("Creator").Value = tool.Parent.Name --Tool > Character > Name
		end
	end
end)

hey you! have you ever heard of enes? if you are in trouble, better call enes!

Make it follow you, by doing Pathfinding or Humanoid:MoveTo().

After that, Make it do a Magnitude check and make a find target function. heres a quick and simple one.

function findTarget() 	
	for i, child in pairs(workspace:GetChildren()) do
		if child:IsA("Model") and child:FindFirstChild("Humanoid") and child:FindFirstChild("HumanoidRootPart") and child ~= script.Parent then
			local HumanoidRootPart = child:FindFirstChild("HumanoidRootPart")
			local HumanoidTarg = child:FindFirstChild("Humanoid")
			local pos = (HumanoidRootPartDummy.Position - HumanoidRootPart.Position).Magnitude
			if pos < range and HumanoidRootPart and HumanoidTarg then
				return HumanoidRootPart, HumanoidTarg
			end
		end
	end	
end

Edit what is necessary.

After that, do this:

while wait() do
	local target, humanoid = findTarget()
	if target.Parent.Name ~= "playerNamewhatEva" and humanoid.health ~= 0 then
		*load and play whatever animation u set up*
		humanoid:TakeDamage(amountOfDamage)
		wait(loadYouPlayed.length)
	else
		loadYouPlayed:Stop()
	end
end

Might have some errors to tweak, good luck on that, I guess.
