Pathfinding NPC stuttering

Help and Feedback Scripting Support
#1

So, i want to make it so that my pathfinding ai doesnt stutter everytime it moves to a waypoint. The issue is that it does stutter and i cant find a way to fix it. I saw solutions on the dev forum, but some of them werent working with the code i had (I didnt know how to implement it) and also they werent using the same npc movement system i did

This is my code

local PathfindingService = game:GetService("PathfindingService")
local Players = game:GetService("Players")

local radius = 100

local function getRandomPosition(center, radius)
	local angle = math.rad(math.random(0, 360))
	local offsetX = math.sin(angle) * radius
	local offsetZ = math.cos(angle) * radius
	return center + Vector3.new(offsetX, 0, offsetZ)
end

local function moveRandomly()
	local npc = script.Parent

	local center = npc.PrimaryPart.Position
	local randomPosition = getRandomPosition(center, radius)

	local path = PathfindingService:CreatePath()
	path:ComputeAsync(npc.PrimaryPart.Position, randomPosition)

	local waypoints = path:GetWaypoints()
	for _, waypoint in ipairs(waypoints) do
		npc.Humanoid:MoveTo(waypoint.Position)
		npc.Humanoid.MoveToFinished:Wait()
	end
end

local function startMovingRandomly()
	while true do
		moveRandomly()
		wait(1)
	end
end

wait(1)
startMovingRandomly()

the reason it’s stuttering is because after it pathfinds to the spot its waiting 1.

while true do
		moveRandomly()
		task.wait() --you still need a wait to prevent the loop from getting 'exhausted' also task.wait is better for the game
	end

i accidentally marked ur stuff as solution even tho idk yet but

local PathfindingService = game:GetService("PathfindingService")
local Players = game:GetService("Players")

local agentParams = {
	AgentRadius = 100,
}

local function getRandomPosition(center, AgentRadius)
	local angle = math.rad(math.random(0, 360))
	local offsetX = math.sin(angle) * agentParams.AgentRadius
	local offsetZ = math.cos(angle) * agentParams.AgentRadius
	return center + Vector3.new(offsetX, 0, offsetZ)
end

local function moveRandomly()
	local npc = script.Parent

	local center = npc.PrimaryPart.Position
	local randomPosition = getRandomPosition(center, agentParams.AgentRadius)

	local path = PathfindingService:CreatePath(agentParams)
	path:ComputeAsync(npc.PrimaryPart.Position, randomPosition)

	local waypoints = path:GetWaypoints()
	for _, waypoint in ipairs(waypoints) do
		npc.Humanoid:MoveTo(waypoint.Position)
		npc.Humanoid.MoveToFinished:Wait()
	end
end

local function startMovingRandomly()
	while true do
		moveRandomly()
		task.wait()
	end
end

wait(1)
startMovingRandomly()

is this how its meant to be now? if not can u tell me where to fix if you know

I fixed it from another dev forum post which told me to change the primary part networkownership to nil
