if you want to make it to save, you have to use a dini , y_ini or any file/database creator
also, if you want to don't save
use

enum sD
      {
          XP
       }
      new DF[MAX_PLAYERS][sD];

     //after OnPlayerDeath
     public OnPlayerDeath(playerid,killerid,reason)
     {
             DF[killerid][XP] += 1;
            SetPlayerScore(killerid,GetPlayerScore(killerid)+DF[killerid][XP]);
