ES3 Save Base and Concrete Classes

Is it possible to have ES3 save both a base class and the inheriting class at the same time?
Example
public class Mine : Building
Should I be able to save the Mine and the Building without having to go through each building type and have them include the properties from the base class I want to save? When I try I can't get the base class to save, just the Mine. I'm considering a rewrite so both classes are separate but it's a lot of work untangling things.

Hi there,
Easy Save indeed stores inheritance, and we don't appear to have any issues with this at our end. To demonstrate:
Code: Select all
using UnityEngine;
public class InheritenceTest : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
ParentClass obj = new ChildClass();
obj.myInt = 456;
ES3.Save("obj", obj);
Debug.Log(ES3.Load<ParentClass>("obj").myInt);
}
public class ParentClass
{
public int myInt = 123;
}
public class ChildClass : ParentClass
{
public string myString = "myStr";
}
}
This will output 456, indicating that the value has been saved and the new instance correctly created.
All the best,
Joel

Is it a problem that I'm using ES3UserType's for both classes?
I've set one up for the base and the derived class and seen how the derived UserType will get reached but not the base. I can see this being useful if I wanted to control each derived class by itself but I'd love for the base to handle all the common properties and then have derived classes just save off the new data they need on top of the base class.

Hi there,
It should still work regardless of whether you have an ES3Type for each or not. You can try this with the InheritenceTest script I created below, and add an ES3Type for ParentClass and ChildClass. Running it will still return 456 after the ES3Types are created.
All the best,
Joel

I've pmed you a copy of my test project showing the issue I'm having. Your example saved the component directly while I'm exclusively saving prefabs with ES3. Perhaps this is a problem? Let me know if I need to rethink how I'm tackling this.

Thanks for sending that over, much appreciated.
It's not saving the 'BaseInt' field because you've created an ES3Type telling it to only save the 'ChildInt' field of the Player class. See the attached screenshot.
All the best,
