I'm trying to make a game, the AI enemy is programmed to go to a random part position in a folder in the workspace and attack a player once they are enough distance away, but when the enemy gets close to my player, the AI stutters, basically stopping for a bit, then starting, then stopping, rinse and repeat. Any help? Here's the script..

local reaper = script.Parent
local humanoid = reaper.Humanoid
reaper.PrimaryPart:SetNetworkOwner(nil)
local PathfindingService = game:GetService("PathfindingService")

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 = (reaper.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude
			
			if distance < maxDistance then
				nearestTarget = target
				maxDistance = distance
			end
		end
	end
	
	return nearestTarget
end

local function getPath(destination)
	local pathParams = {
		["AgentHeight"] = 5.45,
		["AgentRadius"] = 3.757,
		["AgentCanJump"] = false
	}
	local path = PathfindingService:CreatePath(pathParams)

	path:ComputeAsync(reaper.HumanoidRootPart.Position, destination.Position)
	return path
end

local function attack(target)
	local distance = (reaper.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude
	
	if distance > 1 then
		humanoid:MoveTo(target.HumanoidRootPart.Position)
	else
		target.Humanoid.Health = 0
	end
end

local function walkTo(destination)
	local path = getPath(destination)

	for index, waypoint in pairs(path:GetWaypoints()) do
		local target = findTarget()
		if target then
			print("Attacking ", target.Name)
			attack(target)
			break
		else
			print("Moving to ", waypoint.Position)
			humanoid:MoveTo(waypoint.Position)
			humanoid.MoveToFinished:Wait()
		end
	end
end

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