Sort a Dictionary

[Dev_Peashie]

Hiwi! Thank you for reading.
Can someone show me some approaches to sort this Dictionary, no matter ascending or descending, just some approaches to sort it?

local Dic = {}
Dic["156432156"] = {Points = 500, OtherStuff = X}
Dic["234235345"] = {Points = 1100, OtherStuff = X}
Dic["5467456734"] = {Points = 200, OtherStuff = X}

I already did it with my own approach, I just wanna know better ones, can you pls share how you would do it?

How to sort a dictionary in a better way to get a leaderboard?

Hey! If you’re planning on making a Leaderboard you should take a look at OrderedDataStore | Roblox Creator Documentation. Hopefully this article helps you out. There is an example at the bottom of the page.

Cheers

Thank you so much!, but thats not the required scenario in this case. Its not possible to save an OrderedDataStore for a small task like this one.
I just want to find a way to sort a dictionary

Ohh, I see!

Well, then you could technically achieve this with table.sort even if you tried this already.
Important to know with table.sort is, it doesn’t return a table. It replaces the old one.

So this is an example of how to use table.sort:

table.sort(Dic, function(Player1, Player2)
	return Player1.Points > Player2.Points
end)

Maybe this helps for a solution with your problem, let me know if it does or not!
If it doesn’t, maybe also send me a snippet of your table.sort code.

Cheers

Yup, thats exactly what I did, sort the array gotten from the dictionary, then use that sorted array to match it with the dictionary, creating a new dictionary with all players and points ordered. But, if some players has the same amount of points, I bet, weird things will occur.

Im asking for some other approaches to sort a dictionary

I don’t exactly understand what you mean, but would changing

I think thats just a small typo. My issue its not related with using the table.sort with a
function

Just this, can someone show me some approaches to sort this Dictionary, no matter ascending or descending, just some approaches to sort it?

local Dic = {}
Dic["156432156"] = {Points = 500, OtherStuff = X}
Dic["234235345"] = {Points = 1100, OtherStuff = X}
Dic["5467456734"] = {Points = 200, OtherStuff = X}

Dictionaries do not have any real order & so attempting to use table.sort by itself probably holds no promise. You will definitely need to do a little extra work like you’ve been trying to.

For sorting of dictionaries I have always used this method that 1waffle1 goes into detail about here:

Dictionary Sorting

If you want to get a sorted array representation of the contents of a dictionary then store all of the key, value pairs in an array. local array = {} for key, value in pairs(dictionary) do array[#array+1] = {key = key, value = value} end table.sort(array, function(a, b) return a.value > b.value end)

I see no reason this could not work for your use-case because the sorted variant will still hold the indexes thus making it easy to reattach “OtherStuff” on a per index basis after sorting.

This could need some work with a recursive function’s.

[ItzMeZeus_IGotHacked (notzeussz)]

local function Sort(table)
    for I,v in pairs(table) do
        if typeof(v) == "table" then
            Sort(v)
        end
    end
end

Its just, thats what I’ve been doing, when Players has the same amount of Points, what happens? I think weird stuff occurs, thats all. I just wanna know some new approaches to sort a dictionary
