NPC Pathfinding Script makes the npc stutter walk

I am currently using GnomeCode’s pathfinding ai from his game Teddy. It works but the npc stutters a lot.

local teddy = script.Parent
local humanoid = teddy.Humanoid
teddy.PrimaryPart:SetNetworkOwner(nil)

local function canSeeTarget(target)
	local origin = teddy.HumanoidRootPart.Position
	local direction = (target.HumanoidRootPart.Position - teddy.HumanoidRootPart.Position).unit * 40
	local ray = Ray.new(origin, direction)
	
	local hit, pos = workspace:FindPartOnRay(ray, teddy)
	
	
	if hit then
		if hit:IsDescendantOf(target) then
			return true
		end
	else
		return false
	end
end

local function findTarget()
	local players = game.Players:GetPlayers()
	local maxDistance = 40
	local nearestTarget
	
	for index, player in pairs(players) do
		if player.Character then
			local target = player.Character
			local distance = (teddy.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude
			
			if distance < maxDistance and canSeeTarget(target) then
				nearestTarget = target
				maxDistance = distance
			end
		end
	end
	
	return nearestTarget
end

local function getPath(destination)
	local PathfindingService = game:GetService("PathfindingService")
	
	local pathParams = {
		["AgentHeight"] = 15,
		["AgentRadius"] = 4,
		["AgentCanJump"] = false
	}
	
	local path = PathfindingService:CreatePath(pathParams)
	
	path:ComputeAsync(teddy.HumanoidRootPart.Position, destination.Position)
	
	return path
end

local function attack(target)
	local distance = (teddy.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude

	if distance > 8 then
		humanoid:MoveTo(target.HumanoidRootPart.Position)
	else
		local attackAnim = humanoid:LoadAnimation(script.Attack)
		attackAnim:Play()
		target.Humanoid.Health = 0
	end
end

local function walkTo(destination)
	
	local path = getPath(destination)
	
	if path.Status == Enum.PathStatus.Success then
		for index, waypoint in pairs(path:GetWaypoints()) do
			local target = findTarget()
			if target and target.Humanoid.Health > 0 then
				print("TARGET FOUND", target.Name)
				attack(target)
				break
			else
				print("Moving to ", waypoint.Position)
				humanoid:MoveTo(waypoint.Position)
				humanoid.MoveToFinished:Wait()
			end
		end
	else
		humanoid:MoveTo(destination.Position - (teddy.HumanoidRootPart.CFrame.LookVector * 10))
	end
end

function patrol()
	local waypoints = workspace.waypoints:GetChildren()
	local randomNum = math.random(1, #waypoints)
	walkTo(waypoints[randomNum])
end

while wait(0.25) do
	patrol()
end

Any help?

I would assume it has something to do with your animation code

#6

yea it is the humanoidrootpart

#8

i dont think it is cuz when it starts chasing me, the animation runs fine. but when its at the pathfinding part it stutters

#9

Had a similar problem to this and the solution was that the NPC was under player network ownership and I needed to make it have server network ownership

idk why but it still stutters when he walks

#22

Is the animation your playing looped?

#23

it was but now its not looped anymore

#24

it removed it but it still stutters

#25

Ok so i added “WaypointSpacing” and it works now?!

local pathParams = {
		["AgentHeight"] = 13,
		["AgentRadius"] = 4,
		["AgentCanJump"] = false,
		["WaypointSpacing"] = 20
	}
