By default, Databrain uses the Newtonsoft Json library to serialize the data to a json file. It is possible though to serialize the data with a custom serializer such as Odin Serializer.
Simply use the API methods GetSerializableData and SetSerializedData.
Here's a simple example using Odin Serializer:
using OdinSerializer;
// The data library
public DataLibrary data;
public void Save()
{
// Get the serializable data class from the data library
var serializableData = data.GetSerializableData();
// Use Odin Serializer to serialize the data
byte[] bytes = SerializationUtility.SerializeValue(serializableData, DataFormat.Binary);
// Write to a file
System.IO.File.WriteAllBytes(System.IO.Path.Combine(Application.persistentDataPath, "saveFile.data"), bytes);
}
public void Load()
{
// Load the file as bytes
byte[] bytes = System.IO.File.ReadAllBytes(System.IO.Path.Combine(Application.persistentDataPath, "saveFile.data"));
// Deserialize the data using Odin Serializer
var serializableData = SerializationUtility.DeserializeValue<DataLibrary.JsonSerializeableClass>(bytes, DataFormat.Binary);
// Set the data back to the data library.
// This will load the complete data and also calls the OnLoaded event.
data.SetSerializedData(serializableData );
}
