Today, I saw a friend in the Group asking about the best implementation method of the unity Singleton. I often use it below. Post it for your reference.

1. Add a singleton template class

using UnityEngine;public class Singleton<T> : MonoBehaviour where T : MonoBehaviour{    private static T _instance;    private static object _lock = new object ();    public static T Instance     {        get {            if (applicationIsQuitting) {                return null;            }            lock (_lock) {                if (_instance == null) {                    _instance = (T)FindObjectOfType (typeof(T));                    if (FindObjectsOfType (typeof(T)).Length > 1) {                        return _instance;                    }                    if (_instance == null) {                        GameObject singleton = new GameObject ();                        _instance = singleton.AddComponent<T> ();                        singleton.name = "(singleton) " + typeof(T).ToString ();                        DontDestroyOnLoad (singleton);                    }                }                return _instance;            }        }    }    private static bool applicationIsQuitting = false;    public void OnDestroy ()    {        applicationIsQuitting = true;    }}

This is a singleton template class, which is easy to use.

2. define your own Singleton class

using UnityEngine;using System;public class GameManager : Singleton<GameManager> {    public float score;    void Awake () {        this.Init();    }    private void Init() {        // Init code    }}

Iii. Call and use

GameManager.Instance.score = 99;

If you have a better implementation method, we recommend that you.
