Script timeout: exhausted allowed execution time

[HpacAm (Bobo)]

1. What do you want to achieve? uh so i made a pathfinding npc that follows nearest player, i expect it to be optimized

2. What is the issue? Its not optimized and i get the error when i leave and causes lag Workspace.NPC.FollowSystem:50: Script timeout: exhausted allowed execution time

3. What solutions have you tried so far? I looked in dev forum and no post could help me

local RunService = game:GetService("RunService")
local Players = game:GetService("Players")
local PathfindingService = game:GetService("PathfindingService")
local enemy = script.Parent
local humanoid = enemy:FindFirstChildOfClass("Humanoid")

if enemy.PrimaryPart then
	enemy.PrimaryPart:SetNetworkOwner(nil)
else
	warn(enemy.Name, "doesn't have a PrimaryPart set.")
	return
end

local animSaves = enemy:FindFirstChild("AnimSaves")
if animSaves then
	animSaves:Destroy()
end

local function GetNearestPlayer()
	local nearestPlayer, shortestDistance = nil, math.huge

	for _, player in pairs(Players:GetPlayers()) do
		local character = player.Character or player.CharacterAdded:Wait()
		if character then
			
			local primaryPart = character:WaitForChild("HumanoidRootPart") or character.PrimaryPart
			
			if primaryPart then
				local distance = (enemy.PrimaryPart.Position - primaryPart.Position).Magnitude
				if distance < shortestDistance then
					shortestDistance = distance
					nearestPlayer = player
				end
			else
				warn(player.Name, "'s character does not have a PrimaryPart!")
			end
		else
			warn(player.Name, "doesn't have a character loaded!")
		end
	end
	
	return nearestPlayer
end

local function positionCheck(position)
	local partAtPosition = workspace:FindPartOnRayWithIgnoreList(Ray.new(position, Vector3.new(0, -10, 0)), {enemy})
	return partAtPosition ~= nil
end
local function FollowNearestPlayer()
	local nearestPlayer = GetNearestPlayer()
	if nearestPlayer and nearestPlayer.Character and nearestPlayer.Character:FindFirstChild("HumanoidRootPart") or nearestPlayer and nearestPlayer.Character and nearestPlayer.Character.PrimaryPart then

		local randomOffset = Vector3.new(math.random(-10, 10), 0, math.random(-10, 10))
		local targetPosition = playerPosition
		
--		print("Enemy Position:", enemy.PrimaryPart.Position)
--		print("Player Position:", playerPosition)
--		print("Target Position:", targetPosition)
		
		if not positionCheck(enemy.PrimaryPart.Position) then
			warn("Enemy is in the air!")
			return nil
		end

			return nil
		end
		
		local path = PathfindingService:CreatePath({
			AgentRadius = 2,
			AgentHeight = 5,
			AgentCanJump = true,
			AgentMaxSlope = 45,
			AgentCanClimb = true,
		})
		
		local success, errorMessage = pcall(function()
			path:ComputeAsync(enemy.PrimaryPart.Position, targetPosition)
		end)
		
		if success then
--			print("Path successfully computed")
			return path
		else
			warn("Failed to compute path: ", errorMessage)
		end
	else
--		warn("Player primary part is nil or not loaded..")
	end
	
	return nil
end

local function moveToPlayer()
	local nextOffsetTime = tick() + math.random(3, 7)
	
	while enemy and enemy.Parent and humanoid do
		local path
		local currentTick = tick()
		
		if currentTick >= nextOffsetTime then
			path = FollowNearestPlayer()
			nextOffsetTime = currentTick + math.random(3, 7)
		else
			path = FollowNearestPlayer()
		end
		
		if path then
			local waypoints = path:GetWaypoints()

			for _, waypoint in pairs(waypoints) do
				if humanoid then
					humanoid:MoveTo(waypoint.Position)
				end
			end
		else
--			task.wait(1)
		end
	end
end

if enemy then
	task.wait(20)
	moveToPlayer()
end

You need to add a task.wait() to your while loop, it’s crashing your studio.
