Not a problem @franckled.
First let me define some things that will clear up some confusion:
LB_points_list = List of points from the leader board (points and coins are the same in my code)
LB_user_list = List of user names from leader board board
(I get these two lists in the same loop so they coincide with each other. Meaning user names from index 1 of the lists correlates to points of index 1 on the other list.)
App user_name_app = Users name in the database of current user logged in and using the app.
user_coins_app = is the score/points of the current players
App user_rank = gives you the rank of the current user. This is done in the first loop in the function.
App num_leaders = total number of users in the leader board. (See firebase picutre below at the bottom.)
Next lets look at how my database is set up so you can see the formatting since you aren’t strong with objects yet:
Make sure you do this!!!—> When you create your firebase data base make sure to initialize users in the correct order.
Just to start input 2 users and make sure user 1 has more points than user 2. If you don’t do this the code will rank the users wrong.
You asked how to find where a user ranks. It is already done in the blocks. You simply have to set a lablel to see it. For example:
