I was just wondering what the best practice was for constructors and custom classes. Currently I have a MonoBehaviour that contains a List that contains a CustomClassWithoutSerializableAttribute. I want to know the best way to default the third class. It looks like the following:

Character.cs

public class Character : MonoBehaviour
{
    public List<Ability> m_abilities;
}

Ability.cs

[System.Serializable]
public Ability : IAbility
{
    [SerializeField]
    private int m_somethingSetInEditor;

    private Damage m_damage;

    public Ability()
    {
        m_damage = new Damage(10);
    }
}

Damage.cs

public Damage
{
    public Damage(int number)
    {
    }
}

Damage is null at the end of this chain of events. I've been trying to find the best practice for this. Eventually I want to move Ability out of the Inspector, but for now, I want to be able to iterate quickly on this and want to know the best practice for this type of thing.

Should Ability be deriving from ScriptableObject and initializing m_damage in the Start() function?
