Question about datastores

[inland plank]

I have a script which someone helped me make (thank you Von 🙏) which loads a set of values into the player upon joining, i havent done datastores before and before i move onto giving it a go, im wondering if i can data store values that get added to the player, rather than values that are already on the player, it might be a dumb straightforward question to someone who a shred of experience on datastores but i’d like an answer before i move forward

game:GetService("DataStoreService")

you get data you store em in the server for later

this works even offline btw

that how games keep your money saved up

attach the data to the player id

when game is loaded load the data and apply it to a gui or anything like that

[inland plank]

So even if the values are loaded into the player upon joining it can still be datastored?

[hollow flume]

yes

[inland plank]

Thank you 🙏

wait do you mean values givin to the player after they join? yes, any value can be stored into datastores. you'll just have to confirm they have valid data before loading it.

say we have a player state givin right when they leave, say our player is givin the state of "phasefour", we can save that right before they leave then load it when they join.

[hollow flume]

Yes using the roblox escape key thingy

[inland plank]

And maybe this is a stupid question, dont feel obligated to answer but how do i check if theres valid data?

[hollow flume]

You dont

[inland plank]

Input service?

[hollow flume]

You just gamble your luck

[hollow flume]

Yea id rather use that but idk how it works

[wise smelt]

well it depends

in this case i mean valid data as in everything but NIL

-# nil is essentially nothing

we can just check the players data and confirm its NOT nil

[hollow flume]

Remember nan is different than nil

[wise smelt]

if playerdata ~= nil then
  --load your data
end

[inland plank]

So im good to go and i can just load the data and as long as i load it after the values are in the player its fine?

Fuck off mee6

[hollow flume]

hey hes giving you perms

dont be rude

[inland plank]

HE FLAGGED MY MESSAGE

I HATE HIS FACE

[hollow flume]

use nan for numbers nil for objects

[inland plank]

Why cant i use nil?

[wise smelt]

local DSS = game:GetService("DataStoreService")
local Datastore = DSS:GetDataStore("MyStore")

game.Players.PlayerAdded:Connect(function(p)
    local Key = p.UserId
    local PlayerData = Datastore:GetAsync(Key)
    if PlayerData ~= nil then
        -- Data exists!
        print(PlayerData)
    else
        -- Data doesnt exist
        warn("NO DATA FOUND!")
    end
end)

game.Players.PlayerRemoving:Connect(function(p)
    local Key = p.UserId
    Datastore:SetAsync(Key, 10)
end)

here is a basic example of a datastore

[hollow flume]

nan meant not a number

Nil means zero/nothing

[inland plank]

Right right

[inland plank]

Thank you for this

I will be checking out coral game

[hollow flume]

This also works for connection purposes

[wise smelt]

well in some cases you could.

[hollow flume]

Remember he said IN SOME CASES

[wise smelt]

nil again essentially is nothing so in certain cases you could use it

such as throwing an object away from workspace but keeping it in memory

mypart.parent = nil

you can still access "mypart" but it wont be in the workspace

[hollow flume]

I suggest storing it in replicated storage tho

[wise smelt]

depends, if its a sensitive script it would be preferred to store it in serverstorage, replicatedstorage is seen by the client so exploiters have access to everything in it.

[inland plank]

Storing the value in replicated?

[hollow flume]

Yes i suggest using serverstorage for values and replicated storage for models

[inland plank]

Just to clarify….

Models have no need in terms of datastores right?

[wise smelt]

good question, it depends on the game & model.

if you have say a building game you would want to save a table with parts and plot positions in datastore

then load the plot

[hollow flume]

Those are loaded locally so no need

I would racomend that static objcet are loaded in locally

And that models that change overtime be stored in data

Im saving this for later cuz its important

[wise smelt]

? wait i dont get it, please elaborate 👀

[hollow flume]

In grow a garden

Your place changes overtime

[wise smelt]

i dont play gag, do you mean model loading when a player joins?

OH I GOT IT

[hollow flume]

Your almost there

[wise smelt]

so plant growing! gotcha!

[hollow flume]
