npc system

[grim crown]

im trying to make a system where NPCs follow you and you can buy more npcs to follow you but kinda have no idea where to start

[polar musk]

mmm, that's good, so Ig I'll plan a clear plan for you

done!

You've 2 steps !

** # Step 1: NPC follows a player**

- Use Humanoid:MoveTo() or PathfindingService to make NPC move toward player’s character.

- Update target position frequently.

# Step 2: Player can buy NPC followers

**- Keep a value tracking how many NPCs the player owns.

• When player buys, spawn a new NPC and assign it to follow the player.****

dont worry, I'll code u an example with some comments to understand it perfectly !!

** # 1. NPC Follow Script (LocalScript or Script inside NPC model)**

local RunService = game:GetService("RunService")
local npc = script.Parent
local humanoid = npc:WaitForChild("Humanoid")

local targetPlayer = nil
local followDistance = 5

function follow(player)
    targetPlayer = player
    while targetPlayer and targetPlayer.Character and humanoid.Health > 0 do
        local hrp = targetPlayer.Character:FindFirstChild("HumanoidRootPart")
        if hrp then
            local dist = (npc.HumanoidRootPart.Position - hrp.Position).Magnitude
            if dist > followDistance then
                humanoid:MoveTo(hrp.Position)
            else
                humanoid:MoveTo(npc.HumanoidRootPart.Position) -- stop moving
            end
        end
        task.wait(0.5)
    end
end

-- Start following the player when assigned
follow(game.Players:GetPlayers()[1]) -- For testing, follow first player

I'll give you an other one

2. Spawn & Assign NPCs to player (Server Script):

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")
local npcTemplate = ReplicatedStorage:WaitForChild("FollowerNPC")

local playerFollowers = {}

Players.PlayerAdded:Connect(function(player)
    playerFollowers[player.UserId] = {}
end)

function spawnFollower(player)
    local npc = npcTemplate:Clone()
    npc.Parent = workspace
    npc:SetPrimaryPartCFrame(player.Character.HumanoidRootPart.CFrame * CFrame.new(3,0,3))
    
    local followScript = npc:FindFirstChild("FollowScript")
    if followScript then
        followScript.Disabled = false
        followScript:WaitForChild("BindableEvent"):Fire(player) -- Use BindableEvent or remote to tell which player to follow
    end
    
    table.insert(playerFollowers[player.UserId], npc)
end

-- Example buying function
function buyFollower(player)
    spawnFollower(player)
    -- deduct money here
end

3. Tell the NPC who to follow (update FollowScript)

local event = script:WaitForChild("BindableEvent") -- or RemoteEvent for remote communication

event.Event:Connect(function(player)
    follow(player)
end)

Make your FollowScript listen for a BindableEvent or RemoteEvent to know the target player:
