[SerializeReference] is inaccessible due to its protection level

As the title says, I get this error when I try to add this attribute to my List.

My class :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEditor;
5.  
6. [System.Serializable]
7. public class C_SplineV2 : ScriptableObject
8. {
9.     public List<Point> points;
10. }
11.  

I want to add [SerializeReference] to my list but can't because of the error.

The Point class :

Code (CSharp):

1.  
2. [System.Serializable]
3. public class Point
4. {
5.     [SerializeField] public string asset;
6.     [SerializeField] public int id;
7.     [SerializeField] public Vector3 anchor;
8.     [SerializeField] public Vector3 cp1;
9.     [SerializeField] public Vector3 cp2;
10.     [SerializeField] public List<Point> prevPoints = new List<Point>(); // semgent 1
11.     [SerializeField] public List<Point> nextPoints = new List<Point>(); // segment 2
12. }
13.  

I cannot find anyone with the same issue.
Help will be very appreciated ! thanks !

 

You shouldn't need [SerializeField] on your public members, as they'll be serialized by default if you have System.Serializable on your class.

That said I don't know why you'd get the error. Can you copy and paste the full error message?

 

Thanks for the tip ! I'll change that.


The error I get is no more than what the title says. I only get that..

 

Same issues. Any help?
