Bank system I made using dbnpc.

DBNPC Script (Name is BankDB):

PHP Code:

function onCreated()
{
  this.interest = 0.01;
  this.hour = 0;
  Interest();
  setTimer(3600);
}
public function CreateAccount(pl,ammount)
{
  if (this.accounts.index(pl) = -1)
  {
    this.accounts.add(pl);
    this.("acc"@pl) = ammount;
    findplayer(pl).rupees -= ammount;
    return true
  }
  else return false;
}

public function CheckBalance(pl)
{
  if (this.accounts.index(pl) => 0)
  {
    return this.("acc"@pl);
  }
  else return false;
}  

public function AddMoney(pl,ammount)
{
  if (this.accounts.index(pl) => 0)
  {
    findplayer(pl).rupees -= ammount;
    this.("acc"@pl) += ammount;
    return this.("acc"@pl);
  }
  else return false;
}  

public function RemoveMoney(pl,ammount)
{
  if (this.accounts.index(pl) => 0)
  {
    if (this.("acc"@pl) => ammount)
    {
      this.("acc"@pl) -= ammount;
      findplayer(pl).rupees += ammount;
      return true;
    }
    else return "nm";
  }
  else return "na";
}

function onTimeout() 
{
/* Cheers to Kuji for this.hour idea */
  this.hour ++;
  if (this.hour => 24)
  {
    echo("Interest Added");
    Interest();
    this.hour = 0;
  }
setTimer(3600);
} 

public function Interest()
{
  for (int : this.accounts)
  {
    this.("acc"@int) = int(this.("acc"@int) * 1.01);
  }
} 


Manual interest for RC - add this to your Control-NPC

PHP Code:

 function onRCChat()
{
  if (params[0] == "interest")
  {
    if (player.account == "Whoever")
    {
      echo("Manual Interest Added!");
      BankDB.Interest();
    }
  }
} 


And finally some examples on how to use this system in a bank

PHP Code:

/* Do not clientside this script */
function onPlayerChats()
{
  /*Create Account*/
  if (player.chat.starts("/createaccount"))
  {
    temp.result = BankDB.CreateAccount(player.account,player.chat.substring(15,-1));
    if (temp.result == true)
      say2("Account Opened");

    else say2("You already have an account");
   }

  else if (player.chat == "/balance")
  {
    temp.result = BankDB.CheckBalance(player.account);
    if(temp.result != false)
      say2("Current Balance" SPC temp.result);
    else say2("You do not have an account");
   }

   else if (player.chat.starts("/withdraw"))
   {
     temp.result = BankDB.RemoveMoney(player.account,player.chat.substring(10,-1));
     if (temp.result == "na")
       say2("Open an account?");
     else if (temp.result == "nm")
       say2("Not enough money");
     else if (temp.result ==  true)
       say2("Withdrawn");
    }
   else if (player.chat.starts("/deposit"))
   {
        if (player.rupees > player.chat.substring(9,-1))
        {
          temp.result = BankDB.AddMoney(player.account,player.chat.substring(9,-1));
          if (temp.result != false)
            say2("Money Deposited. Balance: " @ temp.result);
          else
            say2("Open an account first");
        }
    }
} 


This system can work on a global scale. One BankDB can serve any ammount of banks. I used a BankDB for a couple of reasons. First off - incredibly easy to add interest now. Secondly - I can use functions to determine who has the most money, total ammount of money etc. (Not included).
