Datastore Question

[foshmee]

Hello! I’m not too good with datastores, but I was wondering how I would add/remove an item that is being saved.

For example, if a new player joins, I would give them some new data such as:

local tableOfData = {
    ["Money"] = 10,
    ["Level"] = 1,
    ["Rank"] = "Noob"
}

However, if they already have data, I would just load it in. I was wondering if there was a way to add a new value to the table for players who already have data saved. I’ve tried something like this:

local tableOfData = {
    ["Money"] = 10,
    ["Level"] = 1,
    ["Rank"] = "Noob"
}

if not table.find(tableOfData[player.UserId], "Diamonds") then
    table.insert(tableOfData[player.UserId], "Diamonds")
    tableOfData[player.UserId].Diamonds = 0
end

But this doesn’t work. I’d like it to be the same the other values. The table should look like this:

local tableOfData = {
    ["Money"] = 10,
    ["Level"] = 1,
    ["Rank"] = "Noob"
    ["Diamonds"] = 0
}

Instead, it looks like this:

local tableOfData = {
    [1] = "Diamonds"
    ["Money"] = 10,
    ["Level"] = 1,
    ["Rank"] = "Noob"
}

I’m not sure how to add it so that the new value is in the same format as the others. Sorry if this question is a bit confusing, but if anyone could help, that would be great! Thanks.

Check if the Player’s Current Data doesnt have this new by Iterating through it:

for index,value in Data do -- Iterates through Starter Data
    if Sessions[Player.UserId][index] == nil then -- if Data doesnt Exist
        Sessions[Player.UserId][index] = value -- adds Data
    end
end

i think you can use table.find() for this however

I can’t believe I didn’t think about that. I’m tired, but thank you!

The reason why its doing [1] = "Diamonds" is that the table.insert() function adds it as if its an array, aka {'a', 'b', 'c'} which is the same thing as a {[1] = 'a', [2] = 'b', [3] = 'c'}, so doing table.insert() into the {'a', 'b', 'c'}, its just creates a new index called 4 and sets it to the value that you passed into the table.insert(). But we are working with dicts (Dictionaries which has a key index), so you have to set the index name aka table[indexName] = value. For example in your case it would be tableOfData['Diamonds'] = 0

I figured that would be the reason. Thank you for the explanation though!

your welcome, sorry if i was late to the party lol

I think this could work:

a = {}

function InsertAndApply(t: {}, value: any, Key: string?)
	local A = table.insert(t, value)
	local index = table.find(t, value)
	
	local CurrentValue
	if index then
		CurrentValue = t[index]
		t[Key] = CurrentValue
    else
        return
	end
	table.remove(t, index)
	
end

InsertAndApply(a, "Hello", "Sup")
print(a)

Could be simplified tho

But there wouldn’t be any use of that since you are just complicating the a["Hello"] = "sup"

[DasKairo (Cairo)]

Still, at least it works

lol

ah yes complicating things that can be redone in one single line. Every developer be like
