SerializeReference

Alchemy supports Unity's [SerializeReference]. By adding the [SerializeReference] attribute, you can edit interfaces or abstract classes in the Inspector.

using System;
using UnityEngine;

public interface IExample { }

[Serializable]
public sealed class ExampleA : IExample
{
    public float alpha;
}

[Serializable]
public sealed class ExampleB : IExample
{
    public Vector3 beta;
}

[Serializable]
public sealed class ExampleC : IExample
{
    public GameObject gamma;
}

public class SerializeReferenceExample : MonoBehaviour
{
    [SerializeReference] public IExample example;
    [SerializeReference] public IExample[] exampleArray;
}

Interfaces and abstract classes are displayed as shown above, and you can select and create subclasses from the dropdown.

For more information about SerializeReference serialization, please refer to Unity's official documentation.
