Setting Up Table For NPC Spawning?

So I am trying to make an area-specific NPC spawning. I have different NPCs set up for different areas.

This is my Area setup

And this is the NPC set up for each area. (The NPCs are in the specific folders)

01--// Variables
02 
03local replicatedStorage = game:GetService("ReplicatedStorage")
04local AreasFolder = game:GetService("Workspace"):WaitForChild("Areas")
05local AreaNPCsFolder = replicatedStorage:WaitForChild("AreaNPCs")
06 
07local AreaNPCs = {}
08 
09for _, Area in pairs(AreasFolder:GetChildren()) do
10    table.insert(AreaNPCs, Area.Name)
11 
12    local NPCs = AreaNPCsFolder:FindFirstChild(Area):GetChildren()
13    table.insert(AreaNPCs[Area], NPCs.Name)
14end

Basically I want the tabled to be formated as shown:

1local AreaNPCs = {
2    ["Spawn"] = {NPC Names Go Here},
3    ["Lava Hot Springs"] = {NPC Names Go Here},
4    ["Nuclear Wasteland"] = {NPC Names Go Here},
5    ["VIP"] = {NPC Names Go Here}
6}

I am quite unsure of what's wrong with this so anything helps.

The :GetChildren() method of Instance returns an array first-descendant objects. As you do with creating dictionary references for each "area", you must iterate through each individual NPC and append their names respectively:

01--###----------[[SERVICES]]----------###--
02local ReplicatedStorage = game:GetService("ReplicatedStorage")
03 
04 
05 
06--###----------[[VARIABLES]]----------###--
07local NPCSpawnAreas = workspace.Areas
08 
09local KnownAreaNPCs = ReplicatedStorage.AreaNPCs
10 
11 
12local AreaNPCArray = {}
13 
14 
15 
16--###----------[[LOGIC]]----------###--
17for _, Area in pairs(NPCSpawnAreas:GetChildren()) do
18    print("Traversing: \""..Area.Name.."\"")
19    ---------------
20    local AreaNPCs = KnownAreaNPCs:FindFirstChild(Area.Name)
21    if (AreaNPCs) then
22        ---------------
23        AreaNPCArray[Area.Name] = {}
24        --// Initialize the dictionary reference/array.
25        ---------------
26        print("Allocated dictionary index \""..Area.Name.."\"\n")
27        ---------------
28        for _, NPC in pairs(AreaNPCs:GetChildren()) do
29            ---------------
30            print("Added NPC name \""..NPC.Name.."\" to dictionary index \""..Area.Name.."\"")
31            ---------------
32            table.insert(AreaNPCArray[Area.Name], NPC.Name)
33        end
34        ---------------
35        print("\n")
36    end
37end

EDIT:

I can assure you that the program is performing the requested task. I recreated the conditions of your game with line-debugging to visually prove this:

Asset outlines can be found here: Workspace folders, ReplicatedStorage folders.

Output confirmation can be found here.

Additionally, I've also adjusted the code above with the necessary print statements.

I actually just got it working.

01--// Variables
02 
03local replicatedStorage = game:GetService("ReplicatedStorage")
04local AreasFolder = game:GetService("Workspace"):WaitForChild("Areas"
05local AreaNPCsFolder = replicatedStorage:WaitForChild("AreaNPCs")
06 
07local AreaNPCs = {}
08 
09--// Main
10for _, Area in pairs(AreaNPCsFolder:GetChildren()) do
11    table.insert(AreaNPCs, Area)
12 
13    local SelectedArea = Area
14    local NPCs = Area:GetChildren()
15    table.insert(AreaNPCs, NPCs)
16end

Thanks for anyone who took a look at this post. I was just trying stuff out and got it working.

The primary issues with your code, was that you first created an index via the Area name, then tried to reference through the Area Instance. NPCs is an array of the Area's children, meaning .Name wouldn't operate in the context you desired. Ziffixture 6913 — 4y

I have written you a program below that can appropriately construct the array you asked for. Ziffixture 6913 — 4y

My mistake I figured out what I was doing wrong, Thanks for the help! 0Vyp 14 — 4y
