Why won't my path finding NPC walk to me?
local mode = "move"
local dist = 50
local hrp = workspace:WaitForChild("humanoid"):WaitForChild("UpperTorso")
while wait() do
for i ,v in pairs(workspace:GetChildren{}) do
local Target = nil
local humanoid = v:FindFirstChild("Humanoid")
if humanoid and v.Parent ~= "humanoid" and v.Name ~= "humanoid" then
print(v.Name)
if (workspace.humanoid.UpperTorso.Position - v:WaitForChild("UpperTorso").Position).magnitude < 500 then
Target = v.UpperTorso.Position
path = game:GetService("PathfindingService"):ComputeRawPathAsync(v.UpperTorso.Position, Target, 600)
points = path:GetPointCoordinates()
game.Workspace.Points:ClearAllChildren()
if mode == "move" then
print(#points)
for Num = 1, #points do
local hum = workspace.humanoid
hum.Humanoid:MoveTo(points[Num])
repeat
distance =(points[Num] - hum.LowerTorso.Position).magnitude
wait()
until distance < 3
end
end
end
end
end
end
'print(#points)' prints 0 when it should be > 0 but i don't know what's wrong with it.

It looks like you are setting the path to go to itself. In line 11, Target is set to the player's upper torso. in line 12, it tries to compute a path from the UpperTorso to target, which is set to UpperTorso. Dudeguy90539 36 — 5y

Thanks you fixed my issue. However, the NPC is really laggy and the script runs many times a second. I tried increasing the time in the wait() but that didn't work. Do you have any fix for this? jalbraek 29 — 5y

i would reccomend making the function run only when someone does something. So like, if you move, it will run the function or something. When you use while wait() do it is running so often it lags guywithapoo 81 — 5y

you can do this and put a value called Target
debugMode = false
targetNPCs = false
--
h = script.Parent.Parent:WaitForChild("Humanoid")
pathService = game:GetService("PathfindingService")
targetV = script.Parent:WaitForChild("Target")
function closestTargetAndPath()
local humanoids = {}
if targetNPCs then
local function recurse(o)
for _,obj in pairs(o:GetChildren()) do
if obj:IsA("Model") then
if obj:findFirstChild("Humanoid") and obj:findFirstChild("Torso") and obj.Humanoid ~= h and obj.Humanoid.Health > 0 and not obj:findFirstChild("ForceField") then
table.insert(humanoids,obj.Humanoid)
end
end
recurse(obj)
end
end
recurse(workspace)
else
for _,v in pairs(game.Players:GetPlayers()) do
if v.Character and v.Character:findFirstChild("HumanoidRootPart") and v.Character:findFirstChild("Humanoid") and v.Character.Humanoid.Health > 0 and not v:findFirstChild("ForceField") then
table.insert(humanoids,v.Character.Humanoid)
end
end
end
local closest,path,dist
for _,humanoid in pairs(humanoids) do
local myPath = pathService:ComputeRawPathAsync(h.Torso.Position,humanoid.Torso.Position,500)
if myPath.Status ~= Enum.PathStatus.FailFinishNotEmpty then
-- Now that we have a successful path, we need to figure out how far we need to actually travel to reach this point.
local myDist = 0
local previous = h.Torso.Position
for _,point in pairs(myPath:GetPointCoordinates()) do
myDist = myDist + (point-previous).magnitude

end
