Whats the best way to do pathfinding chase?

Hello devs! Recently decided to add pathfinding for enemy in my game after a long time, but couldnt go far.

I tried many ways on using pathfind but all of them got the same issue - being “dumb”. (like spinning around on the same place, etc.)

warning: those scripts may look terrible because its a small template part from main AI code

So first I decided to use roblox’s pathfinding service, which code was:

local Humanoid = script.Parent.NPC
local Torso = script.Parent.Torso
local MainTarget = nil --actually, MainTorso is targets torso (function to get closest)
local PFS = game:GetService('PathfindingService')
local path = PFS:CreatePath()
path:ComputeAsync(Torso.Position, MainTarget.Position)

while task.wait() do
	if path.Status == Enum.PathStatus.Success then
		local Points = path:GetWaypoints()
		local Point = Points[3] or Points[2] or Points[1] or Points[0] or MainTarget

		Humanoid:MoveTo(Point.Position, game:GetService("Workspace"):FindFirstChild("Terrain"))
	end
end

this method is bad i’d say, because being dumb as well

2nd method I used which is awful

local Humanoid = script.Parent.NPC
local Torso = script.Parent.Torso
local MainTarget = nil --actually, MainTorso is targets torso (function to get closest)
local PFS = game:GetService('PathfindingService')
local path = PFS:CreatePath()
path:ComputeAsync(Torso.Position, MainTarget.Position)

while task.wait() do
	local PFS = game:GetService('PathfindingService')
	local path = PFS:CreatePath()
	path:ComputeAsync(Torso.Position, MainTarget.Position)


	if path.Status == Enum.PathStatus.Success then
		local Points = path:GetWaypoints()

		for m,n in pairs(Points) do
			local Point = n
			Humanoid:MoveTo(Point.Position, game:GetService("Workspace"):FindFirstChild("Terrain"))
		end
	end
end

3rd method I used which was probably one of the best, but it got a huge issue which is working only of enemy has a trajectory of where character is going to, else enemy will stand still.

CREDITS TO MODULE: SimplePath - Pathfinding Module

local Character = script.Parent
local Torso = Character.Torso
local MainTarget = nil --actually, MainTorso is targets torso (function to get closest)

while task.wait() do
	local path = require(game.ReplicatedStorage.Modules.PathfindModule).new(Character)
	path.Visualize = true
	path:Run(MainTarget)
end

And last one method I’ve used so far got same mistake as 2nd method (spinning around)

CREDITS TO MODULE: EZ Pathfinding V5

local Character = script.Parent
local Torso = Character.Torso
local MainTarget = nil --actually, MainTorso is targets torso (function to get closest)
local Module = require(game.ReplicatedStorage.Modules.PathfindingV5)

while task.wait() do
	LastPathWay = Module.new(Character, MainTarget)
	LastPathWay:Play()
end

Anyone got question how to make perfect AI chasing pathfind? Or maybe any good PF module?
