[Library] samp-account

[Bakr]

samp-account

samp-account was created to allow extensive user-account systems to be streamlined by not worrying about implementation details. This means we can have a fully working user account system, with data loaded from a database, and stored to a database, all with one function call.

samp-account uses the SA:MP native SQLite database system for storage, Slice?s pointers library for data binding, Y_Less? YSI hooks library for callback hooking, and Y_Less' Whirlpool plugin for encryption.

Installation

Simply install to your project:

Code:

sampctl package install bwhitmire55/samp-account

Include in your code and begin using the library:

Code:

#include <account>

Functions

Code:

/*
PARAMS:?
name - The name of the database column to store the data?
type - The psuedo-type of the data (TYPE_INT, TYPE_FLOAT, TYPE_STRING)?
{Float,_}:... - The variable to store the data?
?
RETURNS:?
1 on success, otherwise 0?
*/
stock AddAccountData(const name[ACCOUNT_MAX_COLUMN_NAME], Types: type, {Float,_}:...)

Code:

/*
PARAMS:  
playerid - The playerid to update the database for
{Float,_}:... - Which data to updat  
  
RETURNS:  
1 on success, otherwise 0  
*/
stock UpdateAccountData(playerid, {Float, _}:...);

Code:

/*
PARAMS:?
playerid - The playerid attempting to be registered?
password - The password of the player (in plain text)?
?
RETURNS:?
1 on success, otherwise 0?
*/
stock RegisterPlayer(playerid, const password[])

Code:

/*
PARAMS:?
playerid - The playerid attempting to be logged in?
password - The password of the player (in plain text)?
?
RETURNS:?
1 on success, otherwise 0
*/
stock LoginPlayer(playerid, const password[])

Code:

/*
PARAMS:?
playerid - The playerid to check?
?
RETURNS:?
1 (true) if logged-in, otherwise 0 (false)
*/
bool: IsPlayerLoggedIn(playerid)

Code:

/*
PARAMS:?
playerid - The playerid to check?
?
RETURNS:?
The unique-ID of the player in the database if exists, otherwise 0?
*/
stock GetPlayerUID(playerid)

Usage

Simply create variables in which to store your players? data

Code:

new
? ? gPlayerKills[MAX_PLAYERS],
? ? gPlayerHealth[MAX_PLAYERS],
? ? gPlayerNickname[MAX_PLAYERS][MAX_PLAYER_NAME];

Add that data to the system (and database) via AddAccountData

Code:

public OnGameModeInit() {
? ? AddAccountData("kills", TYPE_INT, gPlayerKills);
? ? AddAccountData("health", TYPE_FLOAT, gPlayerHealth);
? ? AddAccountData("nickname", TYPE_STRING, gPlayerNickname);

? ? return 1;
}

Anytime a user logs into their account, their information will be loaded from the database and into the corresponding variables. Likewise for disconnecting, their data will be updated inside the database.

NOTE: The variables do no reset themselves, so you should zero-out their values upon the player exiting the server.

You are free to use the variables as normal with no effect:

Code:

public OnPlayerDeath(playerid, killerid, reason) {
? ? gPlayerDeaths[playerid];
? ? return 1;
}

Now we just need to call RegisterPlayer or LoginPlayer. This will most likely be done via command/dialog

Code:

ZCMD:register(playerid, params[]) {
? ? if(IsPlayerLoggedIn(playerid)) {
? ? ? ? return SendClientMessage(playerid, 0xFF0000FF, "Already logged-in!");
? ? }

? ? if(isnull(params)) {
? ? ? ? return SendClientMessage(playerid, 0xFFFF00FF, "Usage: /register <password>");
? ? }

? ? if(RegisterPlayer(playerid, params)) {
? ? ? ? SendClientMessage(playerid, 0x00FF00FF, "You have successfully registered an account!");
? ? } else {
? ? ? ? // RegisterPlayer will return 0 if the account already exists, or there is an issue with the database.
? ? ? ? // For this example, we'll assume the former.
? ? ? ? SendClientMessage(playerid, 0xFF0000FF, "Error! This username is already registered.");
? ? }
? ? return 1;
}

And that?s it! You now have a fully working account system, which can store any data you like, without touching a database or file. Nice!

Callbacks

This library also includes two callbacks, OnPlayerRegister and OnPlayerLogin.

Code:

public OnPlayerRegister(playerid) {
? ? SendClientMessageToAll(0x00FF00FF, "A new member has registered!");
? ? return 1;
}

public OnPlayerLogin(playerid) {
? ? SendClientMessageToAll(0x00FF00FF, "An existing member has rejoined us!");
? ? return 1;
}

Macros

All macros are as followed:

Code:

// The database file
#define ACCOUNT_DATABASE? ? ? ? "mydatabase.db"

Code:

// The database table to store the account data
#define ACCOUNT_DATABASE_TABLE? "mydatabasetable"

Code:

// The amount of 'data' you wish to store
// i.e., how many times you will use AddAccountData
#define ACCOUNT_MAX_COLUMNS? ? (100)

Code:

// The maximum length of a column name in the database
#define ACCOUNT_MAX_COLUMN_NAME (24)

All of these can be redefined to suite your script

Code:

#define ACCOUNT_DATABASE? ? ? ? "COD-DB.db"
#define ACCOUNT_DATABASE_TABLE? "users"
#include <account>

Testing

To test, simply run the package:

Code:

sampctl package run
