Adding custom data
For adding custom data to the save system you can right click in you project browser Create > SmartifyOS > Save System > Add Save Data, give the file a name and open it.
In the partial class you can add variables you want to add.
public partial class SaveData
{
   //Add your custom variables here (public)
}
Example:
namespace SmartifyOS.SaveSystem
{
   public partial class SaveData
   {
      public LightController lightController;
   }
   public struct LiveController
   {
      public string arduinoPort;
   }
}
Now you can load and save it just like all other save data.
For loading:
portName = SaveManager.Load().liveController.arduinoPort;
For saving:
SaveManager.Load().liveController.arduinoPort = value
Adding data to SaveData.system
If you want to add custom data to SaveData.system you can just do:
namespace SmartifyOS.SaveSystem
{
   public partial class System
   {
      //Add your custom variables here (public)
   }
}
