你实际上可以通过subscribe来改变你的ScriptableObject类的编辑器的播放模式状态.下面是一个小例子来说明：

#if UNITY_EDITOR
    using UnityEditor;
#endif
using UnityEngine;

namespace SomeNameSpace
{
    [CreateAssetMenu(fileName = "TestScriptableObject", menuName = "ScriptableObjects/")]
    public class TestScriptableObject : ScriptableObject
    {
        private const int DefaultHealth = 120;
        
        public int Health = 60;

        private void OnEnable()
        {
#if UNITY_EDITOR
            // Subscribe for the "event"
            EditorApplication.playModeStateChanged += LogPlayModeState;
#endif
        }

        private void OnDisable()
        {
#if UNITY_EDITOR
            // Don't forget to unsubscribe
            EditorApplication.playModeStateChanged -= LogPlayModeState;
#endif
        }

#if UNITY_EDITOR
        private void LogPlayModeState(PlayModeStateChange state)
        {
            if (state == PlayModeStateChange.ExitingPlayMode)
            {
                // Reset / Set the default health value
                Health = DefaultHealth;
            }
        }
#endif
    }
}

在这种情况下，我使用EditorJsonUtility将初始对象的副本保存为JSON，然后在完成后覆盖目标对象。
在这种情况下，代码类似于：

using UnityEngine;
#if UNITY_EDITOR // makes intent clear.
using UnityEditor;
#endif

[CreateAssetMenu ( fileName = "TestScriptableObject", menuName = "TestScriptableObject", order = 1 )]
public class TestScriptableObject : ScriptableObject
{
    public int Field1;
    public float Field2;
    public Vector2 Field3;

#if UNITY_EDITOR
    [SerializeField] private bool _revert;
    private string _initialJson = string.Empty;
#endif

    private void OnEnable ( )
    {
#if UNITY_EDITOR
        EditorApplication.playModeStateChanged -= OnPlayModeStateChanged;
        EditorApplication.playModeStateChanged += OnPlayModeStateChanged;
#endif
    }

#if UNITY_EDITOR
    private void OnPlayModeStateChanged ( PlayModeStateChange obj )
    {
        switch ( obj )
        {
            case PlayModeStateChange.EnteredPlayMode:
                _initialJson = EditorJsonUtility.ToJson ( this );
                break;

            case PlayModeStateChange.ExitingPlayMode:
                EditorApplication.playModeStateChanged -= OnPlayModeStateChanged;
                if ( _revert )
                    EditorJsonUtility.FromJsonOverwrite ( _initialJson, this );
                break;
        }
    }
#endif
}
