Recently I’ve been working on a backrooms themed game where the exit of each level teleports you to the next one by changing the primary part’s CFrame via :SetPrimaryPartCFrame(). Problem is, after teleporting to any level with NPCs that are supposed to chase you, these just simply ignore you and continue wandering around. I’ve tried changing the AI, searching on the dev forum, yet nothing seems to work.
Currently the NPCs use a slightly modified version of Y3llow Mustang’s Zombie AI, which I’ll leave here:
Code

local grab = script.Parent:WaitForChild("Grab")
local grabAnim = myHuman:LoadAnimation(grab)
grabAnim.Priority = Enum.AnimationPriority.Action
local grabSound = head:WaitForChild("Attack")
local screamSound = head:WaitForChild("Scream")
local moanSound = head:WaitForChild("Moan")
local clone = script.Parent:Clone()
function walkRandomly()
local xRand = math.random(-20,20)
local zRand = math.random(-20,20)
local goal = myRoot.Position + Vector3.new(xRand,0,zRand)
local path = game:GetService("PathfindingService"):CreatePath()
path:ComputeAsync(myRoot.Position, goal)
local waypoints = path:GetWaypoints()
if math.random(20) == 1 then
moanSound:Play()
end
if path.Status == Enum.PathStatus.Success then
for _, waypoint in pairs(waypoints) do
if waypoint.Action == Enum.PathWaypointAction.Jump then
myHuman.Jump = true
end
myHuman:MoveTo(waypoint.Position)
local timeOut = myHuman.MoveToFinished:Wait(1)
if not timeOut then

end
end

Sorry for the bump, but could anyone please take a look at the script?
Been trying several things to fix it, including briefly disabling and re-enabling the AI, but nothing seems to work…
local TweenService = game:GetService("TweenService")
local Exits = {}
for i,v in pairs(workspace:GetChildren()) do
if v.Name == "Level1Entrance" then
table.insert(Exits,v)
end
end
script.Parent.Triggered:Connect(function(plr)
local Tween = TweenService:Create(plr.PlayerGui.MainGUI.BlackScreen,TweenInfo.new(2),{BackgroundTransparency = 0}):Play()
wait(2)
local Teleporter = Exits[math.random(1, #Exits)]
plr.Character:SetPrimaryPartCFrame(Teleporter.SpawnPlace.CFrame)
wait(2)
local Tween = TweenService:Create(plr.PlayerGui.MainGUI.BlackScreen,TweenInfo.new(2),{BackgroundTransparency = 1}):Play()
for i,v in pairs(workspace:GetDescendants()) do
if v.Name == "AI" and v:IsA("Script") then
v.Disabled = true
delay(0.1,function()
v.Disabled = false
end)
end
end
end)
ok, going back to the findTarget function, have you put any print statements in the loop to see if it is even detecting any players in the workspace? And have it print the distance, to see what distance they are. Only do this for the npc’s in the room that they are ignoring you.
Try this for the AI, see if it makes any difference… ALSO remove from your spawn script, the part where it Disable, and Enable the AI scripts.

Thanks, I’ll try this now.
The reason for disabling and re-enabling the AI was that it seemed to work while testing on Studio, but testing on Player didn’t work.
Hmmm… That didn’t seem to work, even tried disabling StreamingEnabled since the player teleports from a pretty large distance (from the yellow square to the gray one, dummies on the middle baseplate for comparison):
