Making multiple NPCs follow with a button

[vinoic]

Hello everyone. I am new to scripting and I am trying to wrap my head around it. The code I have is compiled from tutorials, opensource codes, devforum, etc. for learning purposes, so bare with me if its really bad…

1. What do you want to achieve?

I want to be able to click on a gui so that multiple NPCs within a given distance (say 10 magnitude) will follow the player. Anything beyond 20 studs will disconnect the NPC(s) and will stop following.

2. What is the issue?
   There are multiple NPCs arbitrarily spawned in workspace and when I click on the ‘call’ button, only one random NPC will follow.

3. What solutions have you tried so far?

I’ve tried looking for solutions on developer hub, but I am having trouble finding anything.

This is what was used to spawn arbitrarily positioned NPCs into workspace:

local PhysicsService = game:GetService("PhysicsService")

PhysicsService:RegisterCollisionGroup("Sheep")
PhysicsService:CollisionGroupSetCollidable("Sheep", "Sheep", false)

local sheep = game.ServerStorage.sheep
for _, part in pairs(sheep:GetDescendants()) do
	if part:IsA("BasePart") then
		part.CollisionGroup = "Sheep"
	end
end


-- Clone sheep into workspace
for i=1, 10 do
	local z = sheep:Clone()
	z.Parent = game.Workspace

	z:SetPrimaryPartCFrame(CFrame.new(Vector3.new(math.random(-50,50),5,math.random(-50,50))))
	
end

This is for the NPCs to follow:

-- Services
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local PathfindingService = game:GetService("PathfindingService")
local ServerStorage = game:GetService("ServerStorage")
local WorkSpace = game:GetService("Workspace")

-- Variables
local NPC = WorkSpace.sheep
local NPCHumanoid = WorkSpace.sheep.Humanoid
local NPCHumanoidRoot = WorkSpace.sheep.HumanoidRootPart
local Player = script.Parent -- StartPlayer.StarterCharacterScript is the player already
local PlayerHumanoidRoot = Player.HumanoidRootPart
local fireEvent = game.ReplicatedStorage.AIEvent.OnServerEvent

-- Setting up
NPC.Parent = workspace
NPC.PrimaryPart:SetNetworkOwner(nil)

-- Function
local function FollowPlayer()
	local Path = PathfindingService:CreatePath()
	local MovingToPosition = PlayerHumanoidRoot.Position - Vector3.new(5, 0, 0)
	local ComputedPath = Path:ComputeAsync(NPC.HumanoidRootPart.Position, MovingToPosition)
	return Path
end

-- Event variables
local Stepped
local Distance = (PlayerHumanoidRoot.Position.Magnitude - NPCHumanoidRoot.Position.Magnitude)
-- Movement
fireEvent:Connect(function()
	
	if Distance < 10 then
		
		Stepped = RunService.Stepped:Connect(function()
			FollowPlayer()
			local Path = FollowPlayer()
			for _, waypoint in pairs(Path:GetWaypoints()) do
				NPCHumanoid:MoveTo(waypoint.Position)
			end
			
			-- If distance is large then AI stop following--
			if (PlayerHumanoidRoot.Position.Magnitude - NPCHumanoidRoot.Position.Magnitude) > 20 then
				Stepped:Disconnect()
			end
			
		end)
	end
end)

if fireEvent:Connect() then
	print("Event connected")
end

Any feedback and help is welcomed. Afterall I am still learning.

You only scripted to move one NPC.

Make a folder called “Sheeps” which contains these NPCs.

Replace

for _, waypoint in pairs(Path:GetWaypoints()) do
				NPCHumanoid:MoveTo(waypoint.Position)
			end

with this

for i, v in pairs(workspace.Sheeps:GetChildren()) do
  for _, waypoint in pairs(Path:GetWaypoints()) do
    v.Humanoid:MoveTo(waypoint.Position)
  end
end

It might work.

You only move one NPC

Make a folder inside workspace and name it “Sheeps” move all the sheeps inside that folder

Then get all the sheeps in that folder and their humanoids, and use :MoveTo() with their humanoids

for i,v in pairs(workspace.Sheeps:GetChildren()) do
local NPCHumanoid = v.Humanoid
      for _, waypoint in pairs(Path:GetWaypoints()) do
      NPCHumanoid:MoveTo(waypoint.Position)
      end
end

Nevermind, I figured it out. Thank you all!

[Mighty1964 (shell)]

This is exactly the same as mine but alright then.

[vinoic]

Oh shoot, you’re right. lol whoops

[Mighty1964 (shell)]

Thank you. But also give credit to him as his is more advanced a bit with the variables.
