Hello all 
Thanks for taking a look here.
Below I have an example pathfinder using roblox’s service. In short, I use the first waypoint returned by the service, set my model’s velocity in that direction, then find a new set of way points roughly every tenth of a second.
The performance and script monitor do not report any latency or slowness, however I have noticed that after ~ 1000 iterations or so the waypoint updates start happening significantly slower - the loop is still called, but waypoint.position is nil. It becomes nil most of the time to all of the time past 10,000 ish loops, and becomes nil faster if a player is being tracked/is the target of the wayfinder.
it’s also worth noting in the commented out portion, the ‘marked’ path is still drawn, and path:GetWaypoints() still returns all the waypoints I wanted, even though waypoints[1].Position returns nil.
This results in the ‘mob’ moving slower and slower until it doesn’t move at all.
Any suggestions?
local function createWaypoints()
local waypointMarkers = game.Workspace.WaypointMarkers:GetChildren()
if #waypointMarkers > 0 then
for i,v in ipairs(waypointMarkers) do
v:Destroy()
end
end
local path = Pathfinder:CreatePath({ AgentHeight = 6, AgentRadius = 8, AgentCanJump = false, WaypointSpacing = 8 })
local start = mob.PrimaryPart.Position
local ending = target.Position
local startVector = Vector3.new(start.X, 0, start.Z)
local endVector = Vector3.new(ending.X, 0, ending.Z)
path:ComputeAsync(startVector, endVector)
local waypoints = path:GetWaypoints()
local nextPoint
local success, response = pcall(function()
nextPoint = waypoints[1].Position
local TravelVector = (target.Position - nextPoint).Unit
mob.PrimaryPart.XZVelocity.Velocity = Vector3.new(TravelVector.X*mobSpeed, 0, TravelVector.Z*mobSpeed)
end)
if not success then
print("pathing failure")
end
--for _, waypoint in ipairs(waypoints) do
-- local part = Instance.new("Part")
-- part.Shape = "Ball"
