Laggy/Stuttering NPC Walking

[sinhaleseunit]

I am using SimplePath btw

Sorry for the distance, if you get to close they chase you. If you watch carefully they are stuttering in the distance.

Network Ownership is nil:

ScriptProfiler:

I dunno if this helps or says anything but the NPCSCRIPT is where the pathfinding logic is, there are multiple npcs, minimum 30.

Is there any way I can improve performance?

Without the code or really any information on whats causing it, not alot.

oh ya sorry

local function PatrolToRandomSpot(targetFloor, friendly)
	if not targetFloor then return end

	local floorSize = targetFloor.Size
	local floorCFrame = targetFloor.CFrame

	local randomX = (math.random() - 0.5) * floorSize.X
	local randomZ = (math.random() - 0.5) * floorSize.Z

	local targetPosition = floorCFrame.Position + Vector3.new(randomX, 3, randomZ) -- slightly above floor

	pcall(function()
		NPC.PrimaryPart:SetNetworkOwner(nil)
	end)

	StartPathTo(targetPosition)

	local detectionDistance = 50
	local playerDetected = false

	-- Path recovery
	local blockedConnection = Path.Blocked:Connect(function()
		StartPathTo(targetPosition)
	end)

	local errorConnection = Path.Error:Connect(function()
		StartPathTo(targetPosition)
	end)

	-- Loop check instead of Heartbeat
	while not playerDetected and isPathfinding do
		if IsPlayerNearby(detectionDistance, friendly) then
			playerDetected = true
			state = "Aggressive"
			break
		end
		task.wait(0.2)
	end

	-- Cleanup
	if blockedConnection then blockedConnection:Disconnect() end
	if errorConnection then errorConnection:Disconnect() end

	if not playerDetected then
		task.wait(math.random(2, 5))
	end
end

Also there are a lot of humanoids that are owned by the server, like maybe a hundred cause there are animals and such, does that play a factor?

it’s all pretty simple, roblox is a terrible engine.

in hindsight, maybe, but its almost 2026
