TypeDropdown Attribute

[apilola]

I've written this attribute using the SerializedReference API. It should work with pretty much any Non UnityEngine.Object derived type. Here is an example of it in action. I would submit a pull request for it, but it requires the project to be upgraded to 2021.2.

I could use a preprocessor directive to hide it, after I make my pull request. What are your thoughts?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class AnimalTest : MonoBehaviour
{
    [SerializeReference, TypeDropdown(typeof(Animal))] Animal MyPet;
}

[System.Serializable]
public class Animal
{
    public string nickname = "Silly Billy";
}


public class Dog : Animal
{
    public string Breed = "Golden Retriever";
}

public class Cat : Animal
{
    public int lives = 9;
}

Quck Note:
When switching between types, the property will automatically try to copy any fields from the original object to the destination object.

I am really interested in this !

[apilola]

What do you think? Should I submit a pull request with a preprocessor directive hiding it from older versions of unity?

Hey! What's the progress on this?

[dbrizov]

I am about to merge a lot of pull requests next weekend, so I will include it :)

Does it include? I did not find it in the master branch.

@HaikunHuang This PR has been pending for quite a while, and NaughtyAttributes has not been maintained for years.

I'd like to suggest SaintsField which:

1. Already has this feature included.
2. Support search
3. Has all the features that NaughtyAttributes has, with more.
4. Can be co-exists with NaughtyAttributes so you don't need to migrate your project.

using SaintsField;

[Serializable]
public class Base1Fruit
{
    public GameObject base1;
}

[Serializable]
public class Base2Fruit: Base1Fruit
{
    public int base2;
}

[SerializeReference, ReferencePicker]
public Base2Fruit item;

public interface IRefInterface
{
    public int TheInt { get; }
}

// Omitted other inherent...

[SerializeReference, ReferencePicker]
public IRefInterface myInterface;

It also support field grouping:

using SaintsField;

public interface IRefInterface
{
    public int TheInt { get; }
}

[Serializable]
public struct StructImpl : IRefInterface
{
    [field: SerializeField]
    public int TheInt { get; set; }
    [LayoutStart("Hi", ELayout.FoldoutBox)]
    public string myStruct;

    public ClassDirect nestedClass;
}

[SerializeReference, ReferencePicker, SaintsRow]
public IRefInterface saints;

[SerializeReference, ReferencePicker(hideLabel: true), SaintsRow(inline: true)]
public IRefInterface inline;

Thanks, Tyler. This is very cool!
