Description

Generic class for storing Editor state.

The ScriptableSingleton generic class allows you to create 'Manager' type classes in the Unity Editor. In classes that derive from ScriptableSingleton, serializable data you add survives assembly reloading in the Editor. Also, if the class uses the FilePathAttribute, the serializable data persists between sessions of Unity.

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

[FilePath("SomeSubFolder/StateFile.foo", FilePathAttribute.Location.PreferencesFolder)] public class MySingleton : ScriptableSingleton<MySingleton> { [SerializeField] float m_Number = 42;

[SerializeField] List<string> m_Strings = new List<string>();

public void Modify() { m_Number *= 2; m_Strings.Add("Foo" + m_Number);

Save(true); Debug.Log("Saved to: " + GetFilePath()); }

public void Log() { Debug.Log("MySingleton state: " + JsonUtility.ToJson(this, true)); } }

static class MySingletonMenuItems { [MenuItem("SingletonTest/Log")] static void LogMySingletonState() { MySingleton.instance.Log(); }

[MenuItem("SingletonTest/Modify")] static void ModifyMySingletonState() { MySingleton.instance.Modify(); } }
