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. You can select and instantiate a concrete implementation from the dropdown.

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