I am making a npc pathfinding script. The npc goes to the first destination fine, but when It heads to the second destination it only goes to one waypoint at a time I have tried changing the Wait() at the bottom of the script but after it is finished with the destination 2 it walks about 3 studs away then stops.
code
local PathfindingService = game:GetService("PathfindingService")
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local path = PathfindingService:CreatePath({
AgentRadius = 3,
Costs = {Water = 10,
}
})
wait(2)
local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")
local waypoints
local nextWaypointIndex
local reachedConnection
local blockedConnection
local TEST_DESTINATION = game.Workspace.Well.Main.Position
local TEST_DESTINATION2 = game.Workspace.Table.Main.Position
local function followPath(destination)
-- Compute the path
local success, errorMessage = pcall(function()
path:ComputeAsync(character.PrimaryPart.Position, destination)
end)
if success and path.Status == Enum.PathStatus.Success then
-- Get the path waypoints
waypoints = path:GetWaypoints()
-- Detect if path becomes blocked
blockedConnection = path.Blocked:Connect(function(blockedWaypointIndex)
-- Check if the obstacle is further down the path
if blockedWaypointIndex >= nextWaypointIndex then
-- Stop detecting path blockage until path is re-computed
blockedConnection:Disconnect()
-- Call function to re-compute new path
followPath(destination)
end
end)
-- Detect when movement to next waypoint is complete
if not reachedConnection then
reachedConnection = humanoid.MoveToFinished:Connect(function(reached)
if reached and nextWaypointIndex < #waypoints then
-- Increase waypoint index and move to next waypoint
nextWaypointIndex += 1
humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
else
reachedConnection:Disconnect()
blockedConnection:Disconnect()
end
end)
end
-- Initially move to second waypoint (first waypoint is path start; skip it)
nextWaypointIndex = 2
humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
else
warn("Path not computed!", errorMessage)
end
end
followPath(TEST_DESTINATION)
while true do
wait(5)
if not character:FindFirstChild("Bucket") then
followPath(TEST_DESTINATION)
elseif character:FindFirstChild("Bucket") then
followPath(TEST_DESTINATION2)
end end

I had this same issue, I don’t exactly remember what I did to fix it but if I can remember correctly you would have to set the network owner to nil, this would be at the beginning of the script
local NPC = script.Parent local body = NPC:FindFirstChild(“Torso”) body:SetNetworkOwner(nil)
I don’t know if that is it but I’m pretty sure that is what I did, hope this helps.

Nope, doesn’t help, but thanks for trying.

Hmm, I don’t know what I did then to fix it, I had the same problem but also with other problems as well because I am trying to make a maze like horror game with something patrolling that maze, they would go to different points whilst looking for any players within a certain range
