Constantly changing score keeper

I want to create an app that keeps score with objects constantly getting new points. Like this:

When Round one is done: A = 0 point, B = 1 points C = 2 points

Score:

C

B

A

When Round two is done: A = 1 point, B = 2 points, C = 0 points

B

C

A

Etc... So the letters keeps the points, and the scoreboard changes. Is there an tutorial app that does something like this, that I can build?

You can find that under the search term HIGH SCORE in this board.

No, not a high score... A score keeper or a score board.

Try this ...

Thank you! I will try it

Well, I tried that and I have come that far myself. What I want is a scoreboard that when something gets more points, it rises in the score. That is what I can't figure out.

At this point, I am assuming you have a list of lists (a table),

with each row containing (name, score) and

they are stored in descending score order,

with the row with the highest score at position 1.

I also assume you have a stopper row with score 0 at the end, to make things easy on you.

This two column table can be used as a lookup table using the

lookup-in-pairs block, to tell you what score is in the table for a given name.

Say your new score is in global variable NewScore, for name PlayerName.

You want to see if PlayerName beat his old score, or if he is a new player.

If lookup-in-pairs(ScoreTable, PlayerName, default=0) < NewScore THEN

    (We want to clear any old score for that player, then insert his new score in the right place)

   For Index = length(ScoresTable) to 1 by -1

      If Select item 1 of (Select item Index of ScoreTable) = PlayerName THEN

          Remove item Index from list ScoreTable

   (end For loop)

   (old score cleared, now look for right place to insert new score)

  Set global InsertionPoint to 1

  While (select item 2 from (select item InsertionPoint from ScoreTable)) > NewScore 

     Set global InsertionPoint to InsertionPoint + 1

  (end While)

  (We have skipped past all the higher scores)

  Insert (make a list(PlayerName, NewScore)) at position insertionPoint in list ScoreTable

end If

Thank you, this seems to be what I'm looking for.
