:GetWaypoints returning nil (Pathfinding)

Help and Feedback Scripting Support

#1

i have a script that makes a path to a certain part, however when i print(path:GetWaypoints()) it prints nil
this is the code im using for the path:

local destination = workspace.NunPath:GetChildren()

local points = {}
for _,part in ipairs(destination) do
	table.insert(points,part)
	task.wait()
end
--------
local point = points[math.random(1,#points)]
				local path = PFS:CreatePath({
					AgentRadius = 2,
					AgentHeight = 5,
					AgentCanJump = true
				})
				print(point) --PRINTS THE PART THAT THE NPC IS TRYING TO GO TO
				path:ComputeAsync(npc.HumanoidRootPart.Position, point.Position)
				print(path:GetWaypoints()) --PRINTS NIL
				for _, waypoint in pairs(path:GetWaypoints()) do
				print("should be working") --DOESNT PRINT!!!

Have you checked the path’s status?

--e.g.

if path.Status ~= Enum.PathStatus.Success then
    warn("noooooooooooo path failed")
end

this is the problem, the for _, waypoint never runs, and GetWaypoints is returning nil, however the path does fail because the path never runs
here is more code if needed:

				local point = points[math.random(1,#points)]
				--local path = getPath(RandomSafeArea.Position)
				local path = PFS:CreatePath({
					AgentRadius = 2,
					AgentHeight = 5,
					AgentCanJump = true
				})
				print(point)
				path:ComputeAsync(npc.HumanoidRootPart.Position, point.Position)
				print(path:GetWaypoints())
				if path.Status ~= Enum.PathStatus.Success then
					warn("noooooooooooo path failed")
				end
				for _, waypoint in pairs(path:GetWaypoints()) do
				print("should be working")
					if waypoint.Action == Enum.PathWaypointAction.Jump then
						human.Jump = true
					end
					if waypoint.Action == Enum.PathWaypointAction.Walk then
						human:ChangeState(Enum.HumanoidStateType.Running)
					end
					print("Moving Player")
					human:MoveTo(waypoint)
					human.MoveToFinished:Wait()
					print("Nun Moved Player To Safe Area")
					local RandomAggro = math.random(1,2)
					if RandomAggro == 1 then
						print("Friendly")
					else
						print("Aggro")
						target.Head:Destroy()
						target.Health = 0
					end
				end

By any chance do you have any objects in your workspace that are thousands of studs away from your main pathfinding area? Objects that are extraordinarily far away in the void can cause :CreatePath() to yield indefinitely

The other potential issue is that pathfindingservice is simply not able to create a path from point A to point B. Is there anything blocking the path? Are your walls/floors meshparts?

no

yes, if i remove the doors that block the room the NPC is trying to go to, the for _, waypoint works, buttttt how can i make the npc go to the room, ignoring the door in the way

(also on the side, when the npc is supposed to go to the waypoint and i print the waypoints position, it prints the players position instead of the waypoint)

use pathfinding modifiers with passthrough checked PathfindingModifier

totally forgot modifiers have a pass through option, but i cant even test it due to the npc not going to waypoints like i said here

(if you want the full script i can DM you!)

#8

did you try putting the modifiers in and then seeing if waypoints get created? (i’m assuming you did but just double checking)

#9

dont modifiers make the npc avoid it??? i have another npc has modifiers that the npc avoids with PassThrough

#10

if passthrough is set to true then they should ignore the obstacle(s) that the modifier(s) are parented to,
take a look at Ignoring Obstacles

#11

just tried it and yes the waypoints get created however the waypoints are incorrect like i said here

and when i say “player” i mean the NPC goes to a player, then the code in this topic happens. when i print point.Position it prints correctly, but when i print waypoint.Position it prints incorrectly


				local point = points[math.random(1,#points)]
				--local path = getPath(RandomSafeArea.Position)
				local path = PFS:CreatePath({
					AgentRadius = 2,
					AgentHeight = 5,
					AgentCanJump = true
				})
				print(point) 
				path:ComputeAsync(npc.HumanoidRootPart.Position, point.Position)
				print(path:GetWaypoints())
				print(point.Position) --correct
				if path.Status ~= Enum.PathStatus.Success then
					warn("noooooooooooo path failed")
				end
				for _, waypoint in pairs(path:GetWaypoints()) do
				print("should be working")
				print(waypoint.Position) --incorrect

so this could be related to other code in the script, which is why i said this
