Value Objects or Global Variables?
In my game, I want to store per-player data, for example, how many kills they have, how many items they collected, etc. (Not permanently, just so scripts can work with it.) The way I do this now is that I have a Script detect when a new player joins, and then it creates a Folder under the Player objects and fills it with IntValues and so on. This works pretty well, and is easy to debug because you can see the data without having to print it, but I was wondering if storing data in global (_G. type things) dictionaries would be better. For example, instead of giving each player an IntValue called “kills” and then doing things with that, I would have a global dictionary (_G.playerKills = {} or something like that), and then I would store data using the player’s name. So if I wanted to store 10 kills for player named “TestPlayer”, I would do
1 | _G.playerKills[player.Name] = _G.playerKills[player.Name] + 10 --'player' is the "TestPlayer" player object |
So, what is more efficient? Which method is neater? Which one would you use? Anything helps :D thx

Module Script in ServerStorage:
01 | local SessionData = {} |
02 | local mana = {} |
03 | local money = {} |
04 |
05 | function SessionData:UpdateMana(player, manaValue) |
06 | mana[player] = manaValue |
07 | end |
08 |
09 | function SessionData:GetMana(player) |
10 | return mana[player] |
11 | end |
12 |
13 | function SessionData:UpdateMoney(player, moneyValue) |
14 | money[player] = moneyValue |
15 | end |
16 |
17 | function SessionData:GetMoney(player) |
18 | return money[player] |
19 | end |
20 |
21 | return SessionData |
Example script in workspace part:
01 | local SessionData = require(game.ServerStorage.SessionData) |
02 | local UpdateManaEvent = Instance.new("RemoteEvent") |
03 | UpdateManaEvent.Name = "UpdateManaEvent" |
04 | UpdateManaEvent.Parent = ReplicatedStorage |
05 | mana = script.Parent |
06 | mana.Touched:connect(function(hit) |
07 | local character = hit.Parent |
08 | |
09 | if character:FindFirstChild("HumanoidRootPart") then |
10 | mana:Destroy() |
11 |
12 | --update mana amount |
13 | local player = game.Players:GetPlayerFromCharacter(character) |
14 | local manaValue = SessionData:GetMana(player) |
15 |
16 | manaValue = manaValue + value |
17 | if manaValue > _G.MAX_MANA then |
18 | manaValue = _G.MAX_MANA |
19 | end |
20 |
21 | SessionData:UpdateMana(player,manaValue) |
22 | |
23 | --we need to update mana counter on player GUI as well |
24 | UpdateManaEvent:FireClient(player,manaValue) |
25 |
26 | end |
27 | |
28 | end) |
