I just felt like contributing this bank system, because I haven't contributed anything to the public yet and I think it's about time.
Create a new weapon, it doesn't matter what it's named because it's going to be used just to create the table the bank system is going to use.
Put this in the script of the weapon and update it:
PHP Code:
function onCreated() {
requestsql("CREATE TABLE bankDB (
account TEXT NOT NULL DEFAULT '',
money INTEGER NOT NULL DEFAULT 0
)", false);
}
It's highly recommended to delete the weapon now, it has no further use.
Now you must create a DBNPC that's going to be used for the bank system.
Insert the script below:
PHP Code:
function onCreated() {
this.allowedScripts =
{
this,
"atmclassnamehere"
};
this.echoToRC = false;
this.echoTab = " ";
this.setTypes = {"add", "subtract", "set"};
}
public function BankAccountOpen(pl, echoToRC) {
if (DisableUnauthorized(pl, echoToRC) == true) {
return;
}
temp.req = getsql(
"SELECT *
FROM bankDB
WHERE account = '" @ pl @ "'
", true);
if (req.rows.size() > 0) {
echo("Bank System: The bank account for player '" @ pl @ "' already exists.");
temp.callstack = getcallstack();
echo(this.echoTab @ "Script: " @ GetScriptName());
echo(this.echoTab @ this.echoTab @ "Query: BankAccountOpen(" @ pl @ "," @ echoToRC @ ")");
return;
}
getsql("INSERT INTO bankDB VALUES(
NULL,
'" @ pl @ "',
0
)", false);
if (echoToRC == true || this.echoToRC == true) {
echo("Bank System: A bank account was created for '" @ pl @ "'.");
}
}
public function BankAccountClose(pl, echoToRC) {
if (DisableUnauthorized(pl, echoToRC) == true) {
return;
}
temp.req = getsql(
"SELECT *

WHERE account = '" @ pl @ "'
", true);
if (req.rows.size() < 1) {
echo("Bank System: The bank account for player '" @ pl @ "' does not exist.");
temp.callstack = getcallstack();
echo(this.echoTab @ "Script: " @ GetScriptName());
echo(this.echoTab @ this.echoTab @ "Query: BankAccountClose(" @ pl @ "," @ echoToRC @ ")");
return;
}
getsql("DELETE FROM bankDB

if (echoToRC == true || this.echoToRC == true) {

}
}
public function BankAccountSetMoney(pl, setType, setMoney, echoToRC) {
if (DisableUnauthorized(pl, echoToRC) == true) {
return;
}
temp.money = 0;
if (!(setType in this.setTypes)) {
echo("Bank System: An invalid set type was specified.");
temp.callstack = getcallstack();
echo(this.echoTab @ "Script: " @ GetScriptName());

echo(this.echoTab @ this.echoTab @ "Query: BankAccountSetMoney(" @ pl @ "," @ setType @ "," @ setMoney @ "," @ echoToRC @ ")");
return;
}
temp.oldMoney = req.rows[0].money;
if (setType == "add") {
money = (oldMoney) + setMoney;
}
else if (setType == "subtract") {
money = (oldMoney) - setMoney;
}
else if (setType == "set") {
money = setMoney;
}
getsql(
"UPDATE bankDB

return temp.req;
}
Now for modifications.. Take a look at the top of the script.
See where it says this.allowedScripts={..}? You have to edit it so that certain scripts are allowed to use the Bank System.
If you want the bank system to echo to the RC everytime a command is used, you can set this.echoToRC to true.
Now let me explain how to use this bank system.
There are 5 commands:
PHP Code:
BankAccountOpen("accountname", echoToRC);
This opens up a bank account for the specified account name.
The second parameter is whether or not to echo to RC. Set to true to echo to RC and false to not echo to RC.
PHP Code:
BankAccountClose("accountname", echoToRC);
Closes an existing bank account for a specified account name.
PHP Code:
BankAccountSetMoney("accountname", "add", number, echoToRC);
Set's the amount of money in a bank account. The second parameter can be add, subtract, or set. The third parameter is the amount of money.
PHP Code:
BankAccountViewMoney("accountname", echoToRC);
Returns the amount of money in a player's bank account.
PHP Code:
BankAccountEchoRichest(number);
Echos the richest players, showing account name and amount of money in their bank account. It lists the top 1 to the number specified.
NOTE: If you want to call the bank system's functions from another script you have to put your DBNPC's name as the prefix. e.g. ("BankSystem").BankAccountEchoRichest();
If you have any questions or suggestions please post them.
