Member Function Documentation

ApplyData()

void Backbone::PersistenceManager::ApplyData ( )

private

Applies the loaded data to scene objects.

ApplyEntriesToObjects()

bool Backbone::PersistenceManager::ApplyEntriesToObjects ( List< DataEntry > entries, bool isSceneData )

private

Awake()

void Backbone::PersistenceManager::Awake ( )

private

Initializes the system, setting up the Singleton and JSON serializer.

CollectData()

void Backbone::PersistenceManager::CollectData ( )

private

Collects data marked with persistent attributes and stores them in gameData or sceneData, updating only the current scene and preserving the rest.

CreateDataDictionary()

Dictionary< string, Dictionary< string, DataEntry > > Backbone::PersistenceManager::CreateDataDictionary ( List< DataEntry > dataEntries )

private

Creates a nested dictionary of data entries for quick access.

Decrypt()

string Backbone::PersistenceManager::Decrypt ( byte[] cipherData, string password )

private

Decrypts an AES-encrypted byte array and returns the plain text.

DeriveKey()

byte[] Backbone::PersistenceManager::DeriveKey ( string password, byte[] salt, int keyBytes )

private

Derives a key from a password and salt using PBKDF2.

Encrypt()

byte[] Backbone::PersistenceManager::Encrypt ( string plainText, string password )

private

Encrypts a plain text string with AES and returns the byte array.

GenerateRandomBytes()

byte[] Backbone::PersistenceManager::GenerateRandomBytes ( int count )

private

Generates a random byte array.

GetAvailableSaveSlots()

List< int > Backbone::PersistenceManager::GetAvailableSaveSlots

(

)

Scans the persistent data path for existing save files and returns a list of available save slot numbers (e.g., 0, 1, 2).

Returns

A sorted list of integers representing the slot numbers of existing save files.

GetDataEntry()

DataEntry Backbone::PersistenceManager::GetDataEntry ( Dictionary< string, Dictionary< string, DataEntry > > dataDict, string className, string fieldName )

private

Retrieves a data entry from a nested dictionary.

GetFullHierarchyPath()
