NPCs Stutter while walking (PathfindingService)

[coderluau]

Hiya everyone,

I have recently started developing an NPC system to hone my scripting skills and to experiment with PathfindingService however this bug has been occuring for a few days now and I was not able to find a proper solution.

The problem is, after NPCs reach some random nodes I have given, then start their way to the next node, they do walk there however they start to stutter, doing one step at a time while it was smooth in the beginning

I was thinking it might be about waypoints however I could not find a proper solution.

Any help will be appreciated.

local GuestMover = {}
local PathfindingService = game:GetService("PathfindingService")

function GuestMover:MoveGuest(guest: Instance)
	local Nodes = workspace:WaitForChild("Nodes")

	if not Nodes then 
		warn("No nodes found to move NPCs") 
		return 
	end

	-- Retrieve the humanoid and a random target node
	local Humanoid = guest:WaitForChild("Humanoid")
	local RandomNode = Nodes:GetChildren()[math.random(1, #Nodes:GetChildren())]

	-- Create a path object
	local Path = PathfindingService:CreatePath({
		AgentRadius = 2,  -- Adjust according to your NPC's size
		AgentHeight = 5,  -- Adjust according to your NPC's height
		AgentCanJump = true,
		AgentJumpHeight = 7.2, -- Customize for jump obstacles
		AgentMaxSlope = 45  -- Adjust for sloped terrains
	})

	-- Compute the path to the random node
	Path:ComputeAsync(guest:WaitForChild("HumanoidRootPart").Position, RandomNode.Position)

	if Path.Status == Enum.PathStatus.Success then
		local Waypoints = Path:GetWaypoints()

		for _, Waypoint in ipairs(Waypoints) do
			Humanoid:MoveTo(Waypoint.Position)

			-- If the waypoint requires jumping, trigger jump
			if Waypoint.Action == Enum.PathWaypointAction.Jump then
				Humanoid.Jump = true
			end

			-- Wait until the NPC reaches the current waypoint
			local success = Humanoid.MoveToFinished:Wait()
			if not success then
				warn("Failed to reach waypoint")
				break
			end
		end
	else
		warn("Pathfinding failed")
	end
end

return GuestMover

Try setting network owner of the root part to nil, not certain it’ll fix it but it’s a possibility

It did, thank you so much.
