Issues with pathfinding npc not moving to its destination

Help and Feedback Scripting Support
#1

Hi everyone it’s my first post here on the dev forum I’m so happy to join the community. Please note that I am an amateur scripter so my scripts are not perfect.

Anyways I have been trying to make an extremely simple pathfinding humanoid script for my Roblox game. A couple of days ago it worked completely fine but now it’s not working. I’ve tried to fix it by changing the destination to a different part and he still would not move.


local humanoid = script.Parent.Humanoid
local body = script.Parent:FindFirstChild("HumanoidRootPart") or script.Parent
local destination = game.Workspace.Destination.Position


--path maker
local path = pathfindingService:CreatePath()

--compute path 
path:ComputeAsync(body.Position, destination)


-- get waypoints
local waypoints = path:GetWaypoints()

for k, waypoint in pairs(waypoints) do
	humanoid:MoveTo(waypoints.Position)
	
	if waypoints.Action == Enum.PathWaypointAction.Jump then
	
		humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
	end
	
	humanoid.MoveToFinished:Wait()
end```

My script location.

I think this should be:

humanoid:MoveTo(waypoint.Position)

Here too:

if waypoints.Action

should be:

if waypoint.Action

Ok ill try that sorry for the late response.

Hmm, it did not seem to work but I got a new error “Position is not a valid member of model.” I’m honestly not sure what’s up with this error I tried moving my script around but it did not change anything. The error is on line 12 and I think it’s having trouble finding my “Body” which is referring to the humanoid root part and because I put in body.Position wouldn’t it try to find the humanoid root part position?

Are you sure the character is completely unanchored ?

A Model does not have the property position try replacing the destination variable with this:

local destination = script.Parent:WaitForChild("HumanoidRootPart") or script.Parent.PrimaryPart

Its possible that the model loaded in before its children. Using :WaitForChild is a better alternative to :FindFirstChild as it waits for the humanoid root part to be loaded in

Yes, it’s completely unanchored.

It loaded in and it found my model. :grinning: But now I get a new error “Infinite yield possible on ‘Workspace.NPC:WaitForChild(“HumanoidRootPart”)’.”
