v2 - You can use with same names…

[FIKIR_KUMESI (TÜRKİYE)]

useful extensions exist to add things that are not in KODULAR but also to facilitate things that can be done in KODULAR

here is one of them

[AI_Developer]

What will happen if two users have same score?

[OmerGundogar (Ruwis)]

No problem, add both users to the leaderboard

[Arafat_Junayed (Memo DB)]

how can we use this extension with firebase?

[dora_paz (Dora)]

Get data from firebase, user and points, add them to lists, use extension

[Arafat_Junayed (Memo DB)]

can you send me some picture of blocks how to add firebase data with sort users score? pls dont reject dora_ dora_paz

[Neubady (Eric)]

I have a doubt with this extension.
How to make a list in which the punctuation cannot be lowered, only improve it.
For example if “Jack” has 10 points, play again and get a score of 20 points. But then you only get 5 points and this is where you don’t have to put anything and follow the 20 points.

What is the difference with…

[Discontinued] ListAddon Extension

[ListAddon] ListAddon Extension This extension allows for doing more things with App Inventor Lists. I made this extension with Kodular IDE. Current version: 1 Release date: 2019-04-21T21:00:00Z (UTC) Required permissions: none Min API required: N/A I decided the build this extension because I saw we can actually do more things with YailList (a Java object which used in App Inventor for lists.) So I created additional blocks for the built-in list blocks. Blocks [image] …

[EminTkTr (Emin Hasan)]

i need it too

[novo (nc)]

I’m having a problem, if two users have the same name.
It only shows the score of 1

[Still-learning (1-2-3-4...)]

Doens’t previous js method work for you? Sorted fb tags alphabetically

[novo (nc)]

It works normally, but if there are users with the same name, I get an error
Select list item: Attempt to get item number 5 of a list of length 4:

[Still-learning (1-2-3-4...)]

Can you show me, what did you adjust??

[novo (nc)]

users with different name

two users named Kodular

I didn’t adjust the blocks, they’re still the same.

I managed to succeed that way, but I made a kludge.
When the user creates the account, I save a random number after the name, when I put it in the classification I remove only the numbering.

but there must be some way without changing my firebase structure.

[Still-learning (1-2-3-4...)]

please show your fb struture… I have sughgested the blocks based on your query only…

If you prepare your logic like this then it is easy to sort any type of data with js
3ynrtugft - JavaScript - OneCompiler have a look at this

My Fb :

My Blocks :

App Response :

(One Condition, you must enable this from settings)

[novo (nc)]

@Still-learning

please show your fb struture

this is an example with two users with the same name, which causes a problem with the display

@novo

As I reported earlier, I just got it that way. saving a random number after creating the account and removing the numbering in the display.

[novo (nc)]

I have several scores because they are from different areas.
My issue is only if two people use the same name everything else is working fine.

[Still-learning (1-2-3-4...)]

@novo

the same name

Pls see my previous reply. You have answer in that. The only solution is use sorting based js, you will get exact result

[OmerGundogar (Ruwis)]

Extension updated u can use with same names
