Pathfinding Error with HumanoidRootPart not found?

Help and Feedback Scripting Support
#1

I have a npc which goes and pathfinds directions to random points. The thing is, I keep getting an error that “HumanoidRootPart is not a valid member of Model.” Even though it clearly is. I do not know why this problem is occuring, but I have paused it in the middle of the game and checked and saw that HumanoidRootPart is inside the npc and I used print scripts. Strangely with the print scripts, randomly, it says that the HumaniodRootPart is there, while other times it does. Here is my script:

repeat wait() until script.Parent.Parent.Parent == game.Workspace

local PathfindingService = game:GetService(“PathfindingService”)
function move()
local zombie = script.Parent
local humanoid = zombie.Humanoid
local destination = game.Workspace.NPCPaths:FindFirstChild(math.random(1, 28))

– Create the path object
local path = PathfindingService:CreatePath()

– Compute the path
path:ComputeAsync(zombie.HumanoidRootPart.Position, destination.Position)–error happens here

– Get the path waypoints
local waypoints = path:GetWaypoints()
for _, waypoint in pairs(waypoints) do
local part = Instance.new(“Part”)
part.Shape = “Ball”
part.Material = “Neon”
part.Size = Vector3.new(0.6, 0.6, 0.6)
part.Position = waypoint.Position
part.Anchored = true
part.CanCollide = false
part.Parent = game.Workspace

-- Move zombie to the next waypoint
humanoid:MoveTo(waypoint.Position)
-- Wait until zombie has reached the waypoint before continuing
humanoid.MoveToFinished:Wait()

end
move()
end
move()

Try using WaitForChild() to yield until the HumanoidRootPart is found.

local root = zombie:WaitForChild("HumanoidRootPart")

path:ComputeAsync(root.Position, destination.Position)

I get infinite yield. :confused:

#4

Does your game utilize R15 or R6 characters? And if it’s both then which one are you testing on?

#5

It only uses r6. I tried r15 but couldn’t get animations for it.

#6

Then that’s the issue. I highly doubt that HumanoidRootPart is in R6, instead use Torso

#7

It says Torso is not a valid member of model.

#8

HumanoidRootPart (the invisible torso-like block) is in R6, it’s necessary for humanoid movement.

I’ve also tried running the code @CaptainD_veloper posted in the OP into a sample humanoid model and it does indeed run (after a few minor edits). Make sure that the HumanoidRootPart is in the first parent model in the hierarchy, like Zombie > HumanoidRootPart and that the script is in Zombie.

I have multiple zombies being controlled.

#10

That’s fine, but with the way your script is currently setup it should look like something similar to the image explorer above. The number of zombies aren’t a factor in this.

Oh, still it prints it and im not sure why it does it.
