How to make NPCS not cause lag but also decent movement using pathfinding?
Asked by

I am currently working on a round based game that requires about 36 NPCS that randomly chooses from about 45000 different part to walk to with pathfinding, but their script causes lag, waits a little bit after walking to each waypoint, and also cause wait() to wait a lot more longer than it should. I've tried making one script that controls the NPCS globally and also cloning 2 scripts into each NPC(one for the movement and the other for restarting the movement script if the NPC have been stuck for more than 2 seconds) but it causes even more lag. I've also tried adding a script to the client that hides all NPCS far away from their character and show the ones that are close
This is the movement script
01 | local PathFindingService = game:GetService("PathfindingService") |
03 | local npc = script.Parent |
04 | local Humanoid = npc:WaitForChild("Humanoid") |
05 | local Torso = npc:WaitForChild("HumanoidRootPart") |
06 | local Left = npc:WaitForChild("Left Leg") |
07 | local Right = npc:WaitForChild("Right Leg") |
09 | local height = npc.Head.size.Y + npc.Torso.size.Y + npc["Left Leg"].size.Y |
10 | local diameter = npc["Left Arm"].size.X + npc.Torso.size.X + npc["Right Arm"].size.X |
13 | ["AgentHeight"] = math.ceil(height) , |
14 | ["AgentRadius"] = math.ceil(diameter/2), |
15 | ["AgentCanJump"] = true |
24 | local path = PathFindingService:CreatePath(pathParams) |
28 | path:ComputeAsync(npc.Torso.Position, game.ReplicatedStorage.paths_folder.paths:GetChildren()[math.random(1, #game.ReplicatedStorage.paths_folder.paths:GetChildren())].Position) |
32 | local waypoints = path:GetWaypoints() |
36 | if path.Status == Enum.PathStatus.Success then |
40 | for i = 1, #waypoints do |
44 | if waypoints[i].Action == Enum.PathWaypointAction.Jump then |
46 | Humanoid:ChangeState(Enum.HumanoidStateType.Jumping) |
50 | Humanoid:MoveTo(waypoints[i].Position) |
52 | Humanoid.MoveToFinished:Wait() |
This is the script that detects when the NPC has stopped moving for more than 2 second
01 | local npc = script.Parent |
02 | local root = npc.HumanoidRootPart |
04 | local max_stop_time = 2 |
06 | local function check(pos) |
07 | local amount = max_stop_time / 0.1 |
11 | if root.Position ~= pos then |
14 | elseif amount <= 0 and root.Position == pos then |
16 | if npc:FindFirstChild("npc_ai") then |
17 | npc.npc_ai.Disabled = true |
19 | npc.npc_ai.Disabled = false |
Client code that makes all NPCS far away invisible
01 | local npcs = workspace:WaitForChild("npcs",5) |
03 | local camera = workspace.CurrentCamera |
05 | local maxdistance = 120 |
12 | camera:GetPropertyChangedSignal("CFrame"):Connect(function() |
14 | if #workspace.npcs:GetChildren() > 0 and camera.CameraSubject and game.Players:GetPlayerFromCharacter(camera.CameraSubject.Parent) and camera.CameraSubject.Parent:FindFirstChild("Head") then |
16 | for _,a in pairs(workspace.npcs:GetChildren()) do |
19 | if child:IsA("Model") then |
21 | local humanoid = child:FindFirstChild("Humanoid") |
22 | local rootP = child:FindFirstChild("HumanoidRootPart") |
23 | local animate = child:FindFirstChild("Animate") |
25 | if humanoid and rootP and animate then |
28 | if (rootP.Position - camera.CameraSubject.Parent.Head.Position).Magnitude > maxdistance then |
31 | for _,v in pairs(child:GetDescendants()) do |
32 | if v:IsA("BasePart") or v:IsA("Decal") then |
40 | for _,v in pairs(child:GetDescendants()) do |
41 | if (v:IsA("BasePart") and v.Name ~= "HumanoidRootPart") or (v:IsA("Decal")) then |
All I want is for the NPCS to move to random parts from a folder with pathfinding and not cause that much of a lag on the server
If I didn't make any sense please tell me, its my first post.
