Im confused, if it’s always going to be true how come in the output it didn’t give any error?
Have you checked if it even reaches that part of the script?

I see in your code you said “humanoid:MoveToFinishedWait(2)” when it should be 'humanoid.MoveToFinished:Wait(2)"
Here is a fixed version
local npc = script.Parent
local humanoid = npc:WaitForChild("Humanoid")
local person = npc:WaitForChild("HumanoidRootPart")
local numWaypoints = 1
local goal = workspace.goal.Position
local pathService = game:GetService("PathfindingService")
function walkForward()
local path = pathService:CreatePath({AgentRadius = 4,
AgentHeight = 6, WaypointSpacing = 1, AgentCanJump = true, AgentCanClimb = true
})
path:computeAsync(person.Position, goal)
local waypoints = path:GetWaypoints()
if pathService:FindPathAsync(person.Position,goal) == Enum.PathStatus.NoPath then
error("no path")
end
if waypoints == 0 or nil then
error("waypoints is either nil or 0")
end
for i, waypoint in pairs(waypoints) do
print("for loop running")
print(waypoint.Position)
humanoid:MoveTo(waypoint.Position)
humanoid.MoveToFinished:Wait(2)
end
--local function blockedPath(blockedWaypointIdx) not sure if i really need this
-- local path = pathService:CreatePath()
-- if blockedWaypointIdx > numWaypoints then
-- path:computeAsync(person.Position, goal)
-- if path.Status == Enum.PathStatus.Success then
-- walkForward()
-- else
-- error("path not found")
-- end
-- end
--end
--path.Blocked:Connect(blockedPath)
humanoid:MoveTo(goal)
end
while true do
walkForward()
task.wait(1)
end

Nope, after checking it seems like it should though. Which makes me even more confused.
Thanks, I have a question. Randomly I keep getting this error “PathfindingService: Path request failed due to a navmesh update error”. Is this my fault?
I don’t think they’ve solved this yet, but from the sound of it, if you have any meshes, it could be the problem.

Make some tests using the print function.

Well I have 7.2k mesh parts so um maybe that’s the problem.

Im not sure if this is what you wanted me to do but all of the numbers were printed so I think it would have to go through the if statement.
That does not make sense, as if waypoints == 0 or nil then always returns true and should output the error, can you try putting a print inside that if statement?

I think I am doing something wrong because it returns nil…
print(waypoints == 0 or nil)
This also returned false.
print(waypoints == 0 or waypoints == nil)
Try running this:
local npc = script.Parent
local humanoid = npc:WaitForChild("Humanoid")
local person = npc:WaitForChild("HumanoidRootPart")
local goal = workspace.goal.Position
local pathService = game:GetService("PathfindingService")
function walkForward()
print("1")
local path = pathService:CreatePath({
AgentRadius = 4,
AgentHeight = 6,
WaypointSpacing = 1,
AgentCanJump = true,
AgentCanClimb = true
})
print("2")
path:ComputeAsync(person.Position, goal)
print("3")
local pathStatus = path.Status
if pathStatus == Enum.PathStatus.NoPath then
error("no pathing found")
elseif pathStatus == Enum.PathStatus.Complete then
local waypoints = path:GetWaypoints()
for i, waypoint in pairs(waypoints) do
print("flag lr")
print(waypoint.Position)
humanoid:MoveTo(waypoint.Position)
humanoid.MoveToFinished:Wait()
end
else
error("path status: " .. tostring(pathStatus))
end
print("8")
humanoid:MoveTo(goal)
end
while true do
walkForward()

Yea it gives an error now
if pathStatus == Enum.PathStatus.NoPath then
error("no pathing found")
Have you turned on any of the visuals like “show navigation mesh” to see what it’s seeing?

Sorry I don’t have an answer for you, but that is the problem. I am away right now and will try to help more if needed when I get home.

Alright thanks for the help! 
It turns out I can see the visualizations on my friends game but not on my game… I think it’s because it cant make a path.
Does it show on the land below the parts in your game?
