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(); } }
| instance | Gets the instance of the Singleton. Unity creates the Singleton instance when this property is accessed for the first time. If you use the FilePathAttribute, then Unity loads the data on the first access as well. |
| Save | Saves the current state of the ScriptableSingleton. |
| GetFilePath | Get the file path where this ScriptableSingleton is saved to. |
| GetInstanceID | 返回对象的实例 ID。 |
| ToString | 返回对象的名称。 |
| Destroy | 移除 GameObject、组件或资源。 |
| DestroyImmediate | 立即销毁对象 /obj/。强烈建议您改用 Destroy。 |
| DontDestroyOnLoad | 在加载新的 Scene 时，请勿销毁 Object。 |
| FindObjectOfType | 返回第一个类型为 type 的已加载的激活对象。 |
| FindObjectsOfType | Gets a list of all loaded objects of Type type. |
| Instantiate | 克隆 original 对象并返回克隆对象。 |
| CreateInstance | 创建脚本化对象的实例。 |
| bool | 该对象是否存在？ |
| operator != | 比较两个对象是否引用不同的对象。 |
| operator == | 比较两个对象引用，判断它们是否引用同一个对象。 |
