Subassets management

@todo

Usage example

An asset that represents a playable card in a game, with effects attached as subassets:

using UnityEngine;
using SideXP.Core;
[CreateAssetMenu(fileName = "NewCard", menuName = "Create Card Asset")]
public class CardSO : ScriptableObject
{
    [TextArea(3, 6)]
    public string description;

    // To store a single subasset, you must use the [Subasset] attribute
    [Space]
    [Subasset]
    public CardEffectBase EffectOnDraw = null;

    // To store a list of subassets, just use the SubassetsList<T> type
    [Space]
    public SubassetsList<CardEffectBase> EffectsOnPlay = new SubassetsList<CardEffectBase>();

    [Space]
    [Subasset]
    public CardEffectBase EffectOnDiscard = null;
}

Base effect class:

using UnityEngine;
public abstract class CardEffectBase : ScriptableObject
{
    public abstract bool Apply();
}

Demo increase points effect:

using UnityEngine;
using SideXP.Core;
[SubassetLabel("Increase points by [amount]")]
public class CardEffect_IncreasePoints : CardEffectBase
{
    public int amount;

    public override bool Apply()
    {
        Debug.Log($"Add {amount} points to player");
        return true;
    }
}

Demo add card to deck effect:

using UnityEngine;
using SideXP.Core;
[SubassetLabel("Add [card] to deck")]
public class CardEffect_AddCardToDeck : CardEffectBase
{
    public CardSO card;

    public override bool Apply()
    {
        Debug.Log($"Add card {card.name} to deck");
        return true;
    }
}

Demo add effect to cards effect:

using UnityEngine;
using SideXP.Core;
[SubassetLabel("Add [effect] to all [card] instances")]
public class CardEffect_AddEffectToCards : CardEffectBase
{
    [Subasset]
    public CardEffectBase effectToAdd;
    public CardSO card;

    public override bool Apply()
    {
        Debug.Log($"Add the effect {effectToAdd.name} to all cards instanced from {card.name}");
        return true;
    }
}

You will be able to create a new Card asset from Assets > Create > Create Card Asset.
