Why is my NPC walking kind of "stuttering"? Like, it walks a little and then stops

[EscOFC4214 (Esc)]

I’m having a problem with pathfinding, and i dont know how to fix it

Script:

local npc = script.Parent
local humanoid = npc:FindFirstChild("Humanoid")
local initialPosition = npc.PrimaryPart.Position
local randomWalkRadius = 0 -- Raio de andar aleatoriamente
local detectionRadius = 50 -- Raio de detecção do jogador
local followRadius = 50 -- Raio máximo para seguir o jogador
local canJump = true -- Define se o NPC pode pular ou não
local CanNotWalkInPublic = true
local pathfindingService = game:GetService("PathfindingService")
local randomMoveWaitTimeMin = 1
local randomMoveWaitTimeMax = 10

-- Verifica se o jogador está olhando para o NPC
local function isPlayerLooking(player)
	if not CanNotWalkInPublic then return false end -- Se WalkInPublic for falso, ignora essa verificação
	local playerRootPart = player.Character and player.Character:FindFirstChild("HumanoidRootPart")
	if playerRootPart then
		local npcDirection = (npc.PrimaryPart.Position - playerRootPart.Position).Unit
		local playerLookDirection = playerRootPart.CFrame.LookVector
		local dotProduct = npcDirection:Dot(playerLookDirection)
		return dotProduct > 0.5
	end
	return false
end


-- Ancorar ou desancorar todas as Parts do NPC
local function setNPCAnchored(state)
	for _, part in ipairs(npc:GetDescendants()) do
		if part:IsA("BasePart") then
			part.Anchored = state
		end
	end
end

-- Movimento aleatório
function moveRandomly()
	local retries = 0
	local moved = false
	while not moved and retries < 5 do
		local targetPosition = initialPosition + Vector3.new(
			math.random(-randomWalkRadius, randomWalkRadius),
			0,
			math.random(-randomWalkRadius, randomWalkRadius)
		)
		local path = pathfindingService:CreatePath({
			AgentCanJump = canJump,
			AgentJumpHeight = humanoid.JumpHeight,
			AgentMaxSlopeAngle = humanoid.MaxSlopeAngle
		})
		path:ComputeAsync(npc.PrimaryPart.Position, targetPosition)
		local waypoints = path:GetWaypoints()
		if #waypoints > 0 then
			for _, waypoint in ipairs(waypoints) do
				humanoid:MoveTo(waypoint.Position)
				if waypoint.Action == Enum.PathWaypointAction.Jump then
					humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
				end
				humanoid.MoveToFinished:Wait(math.random(randomMoveWaitTimeMin, randomMoveWaitTimeMax))
				moved = true
			end
		end
		retries = retries + 1
	end
end

-- Seguir jogador
function followPlayer(player)
	local playerRootPart = player.Character and player.Character:FindFirstChild("HumanoidRootPart")
	if playerRootPart then
		local path = pathfindingService:CreatePath({
			AgentCanJump = canJump,
			AgentJumpHeight = humanoid.JumpHeight,
			AgentMaxSlopeAngle = humanoid.MaxSlopeAngle
		})
		path:ComputeAsync(npc.PrimaryPart.Position, playerRootPart.Position)
		local waypoints = path:GetWaypoints()
		if #waypoints > 0 then
			for _, waypoint in ipairs(waypoints) do
				if isPlayerLooking(player) then
					humanoid:MoveTo(npc.PrimaryPart.Position)
					setNPCAnchored(true)
					return
				else
					setNPCAnchored(false)
				end

				humanoid:MoveTo(waypoint.Position)
				if waypoint.Action == Enum.PathWaypointAction.Jump then
					humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
				end
				humanoid.MoveToFinished:Wait()
			end
		end
	end
end

-- Comportamento
function npcBehavior()
	while true do
		local closestPlayer = nil
		local closestDistance = detectionRadius

		for _, player in pairs(game.Players:GetPlayers()) do
			local playerRootPart = player.Character and player.Character:FindFirstChild("HumanoidRootPart")
			if playerRootPart then
				local distance = (playerRootPart.Position - npc.PrimaryPart.Position).Magnitude
				if distance <= closestDistance then
					closestPlayer = player
					closestDistance = distance
				end
			end
		end

		if closestPlayer then
			if isPlayerLooking(closestPlayer) then
				setNPCAnchored(true)
				humanoid:MoveTo(npc.PrimaryPart.Position)
			else
				setNPCAnchored(false)
				followPlayer(closestPlayer)
			end
		else
			setNPCAnchored(false)
			moveRandomly()
		end

		wait(0.1)
	end
end

I tried your code and did a quick search on the devforum, I found this post that shares the same problem as you with a solution that might help you Pathfinding NPC eventually coming to a stop (Waypoint iteration stopping?) - #3 by huh_crazy

Replace npcBehaviour function with this:

local RunService = game:GetService("RunService")

function npcBehavior()
	RunService.Heartbeat:Connect(function()
		local closestPlayer = nil
		local closestDistance = detectionRadius

		for _, player in pairs(game.Players:GetPlayers()) do
			local playerRootPart = player.Character and player.Character:FindFirstChild("HumanoidRootPart")
			if playerRootPart then
				local distance = (playerRootPart.Position - npc.PrimaryPart.Position).Magnitude
				if distance <= closestDistance then
					closestPlayer = player
					closestDistance = distance
				end
			end
		end

		if closestPlayer then
			if isPlayerLooking(closestPlayer) then
				setNPCAnchored(true)
				humanoid:MoveTo(npc.PrimaryPart.Position)
			else
				setNPCAnchored(false)
				followPlayer(closestPlayer)
			end
		else
			setNPCAnchored(false)
			moveRandomly()
		end
	end)
end
npcBehavior()

Step number 1, do not use movetofinished.
step number 2, use setnetworkownernil

Step number 2, here is your edited code.

local function setNPCAnchored(state)
	for _, part in ipairs(npc:GetDescendants()) do
		if part:IsA("BasePart") then
			part.Anchored = state
                        if state == false then part:SetNetworkOwner(nil) end
		end
	end
end

And for number 1.

humanoid:MoveTo(waypoint.Position)
if waypoint.Action == Enum.PathWaypointAction.Jump then
	humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
end
local precision = 6 --// change this to be smaller but big enough so he goes to waypoints
local dist = (npc.PrimaryPart.Position - waypoint.Position).Magnitude  
repeat task.wait() dist = (npc.PrimaryPart.Position - waypoint.Position).Magnitude until dist <= precision

Nevermind I misread part of the script
