The only possibility I can think of, is that Path:GetWaypoints has a new bug that causes it to occasionally return nil. According to the Documentation,
, even if the path fails to be computed, it shouldn’t return nil.
Also, in your video, the error says it’s coming from like 364, but on the latest version of SimplePath (from March of 2022), the Module is only 350 lines long:
And, for the elseif #self._waypoint == 2 then code to be reached, you would have to have a non-Humanoid NPC. Is it? But, these are more secondary questions, not really related to your actual issue.
Anyway, you can report this as a bug. The only way for self._waypoints to be nil, would be for Path:GetWaypoints to return nil, and there was recently a bug report for PathfindingService causing a crash, so maybe there have been some internal changes and this new bug slipped through the cracks.
As a workaround, you can add an additional condition to the SimplePath code, and change this block of code:
--Begin pathfinding
if self._humanoid then
self._humanoid:MoveTo(self._waypoints[self._currentWaypoint].Position)
elseif #self._waypoints == 2 then
self._target = nil
self._visualWaypoints = destroyVisualWaypoints(self._visualWaypoints)
self._events.Reached:Fire(self._agent, self._waypoints[2])
else
self._currentWaypoint = getNonHumanoidWaypoint(self)
moveToFinished(self, true)
end
, to this:
--Begin pathfinding
-- If `_waypoints` is `nil` due to the `Path:GetWaypoints` bug,
if not self._waypoints then
-- , create our own waypoints list directing the NPC
-- to just move in a straight line to their target
self._waypoints = {
PathWaypoint.new(
self._agent.PrimaryPart.Position,
Enum.PathWaypointAction.Walk
),
-- A Jump waypoint to our target position
-- `Enum.PathWaypointAction.Jump` could be changed to
-- `Enum.PathWaypointAction.Walk` if you don't want the
-- agent to jump
PathWaypoint.new(
(typeof(target) == "Vector3" and target) or target.Position),
Enum.PathWaypointAction.Jump
)
}
end
if self._humanoid then
self._humanoid:MoveTo(self._waypoints[self._currentWaypoint].Position)
elseif #self._waypoints == 2 then
self._target = nil
self._visualWaypoints = destroyVisualWaypoints(self._visualWaypoints)
self._events.Reached:Fire(self._agent, self._waypoints[2])
else
self._currentWaypoint = getNonHumanoidWaypoint(self)
moveToFinished(self, true)
end
Check for errors before running, I just wrote this out in the DevForum Reply Editor thing, I didn’t test it out.
