[HowTo] Creating TOP lists.

Most of server admins want to get TOP lists of players on their servers. And you don't need to create hard coded pieces of code. It'll be something like this:

pawn Код:

stock fill ( array[][] )
{
  new x_count;
  for ( new g = 0; g < MAX_PLAYERS; g++ )
    if ( IsPlayerConnected ( g ) )
    {
      x_count++;
      array[g][1] = g;
      array[g][0] = GetPlayerScore ( g );
    }
  return x_count;
}

This function fills the array with our players data. You can use everything instead of GetPlayerScore ( g ); Also it returns count of online players, because we don't want to sort extra sells.

pawn Код:

stock process ( array[][] , size = sizeof ( array ) )
{
  if ( size > 1 )
  {
    new
      bool:flag,
      tmpx;
    do
    {
      flag = true;
      for ( new i = size - 1; i > 0; i-- )
        if ( array[i][0] < array[i - 1][0] )
        {
          tmpx = array[i][0];
          array[i][0] = array[i - 1][0];
          array[i - 1][0] = tmpx;
          tmpx = array[i][1];
          array[i][1] = array[i - 1][1];
          array[i - 1][1] = tmpx;
          flag = false;
        }
    }
    while flag == false;
  }
}

This function sorts the array by using bubble sorting method (for more information about this method click here).
Function will not be processed if there is only 1 player or there is no players on the server.

We'll get array[][1] - TOP playerid and array[][0] - TOP player's score/money/health/time in race etc...

And then, for example to create TOP 10 players, we should write something like this:

pawn Код:

stock CreateTop ( array[][] , max , count = 10 )
{
    new
        str[64],
        pln[24];
    for ( new i = 0; i < ( ( max < count) ? max : count ); i++ )
    {
      GetPlayerName ( array[i][1] , pln , sizeof ( pln ) );
      format( str , sizeof ( str ) , "%d.%s: %d" , i + 1 , pln , array[i][0] );
      SendClientMessageToAll ( 0x33FF33AA , str );
    }
    return true;
}

In this function we must check the count of online players, so we'll use the count from fill function.

Online players >= TOP list count - OK!
Online players < TOP list count - Failure!

pawn Код:

( ( max < count) ? max : count )

Return the lesser value.

It'll print count lines ( default = 10 ) in game chat if the count of online player will be >= 10.

So the usage:

pawn Код:

new
        ar[MAX_PLAYERS][2],
        tmpsize;
    tmpsize = fill ( ar );
    process( ar , tmpsize );
    CreateTop ( ar , tmpsize );

It's just 6 lines to create a TOP list Forget about previous functions and add them in include.

I think it'll help someone.
