单例模式基类

类不继承mono的单例基类

/// <summary>
/// 单例基类
/// </summary>
//泛型解决，给他一个约束要么是这个类本身要么是它的子类
public class SingleBase<T>where T : SingleBase<T>
{
    protected SingleBase() { }

    //线程锁。当多线程访问时，同一时刻仅允许一个线程访问。
    private static object locker=new object();

    //volatile关键字修饰字段是当多个线程都对他进行修改时，确保这个字段在任何时刻呈现都是最新的值
    private volatile  static T _instance;
    public static T Instance
    {
        get
        {
            //双重保证对象的唯一性
            if (_instance == null)
            {
                lock (locker)
                {
                    if (_instance == null)
                    {
                        //使用反射调用无参构造方法创建对象,就是new一个对象的意思
                        _instance = Activator.CreateInstance(typeof(T), true) as T;
                    }
                }
            }
            return _instance;
        }
    }
}

继承单例基类就不用再写了

public class PlayerModel:SingleBase<PlayerModel>
{
    private PlayerModel() { }
    
    public int money=1000;

    public int diamond = 888;

    public void Show()
    {
        Debug.Log(money);
        Debug.Log(diamond);
    }
}

PlayerModel.Instance.Show();

类继承mono的单例基类

/// <summary>
/// 继承monobehaviour的单例基类,前面是继承，where后面是泛型约束，要么是本身，要么是继承monobehaviour
/// </summary>
public class SingleMonoBase<T> : MonoBehaviour where T : MonoBehaviour
{
    protected SingleMonoBase() { }

    //声明一个isExisted属性用来表示单例对象是否存在，用来记录单例对象是否存在，用于防止在OnDestroy方法中访问单例对象报错。
    public static bool isExisted { get; private set; } = false;

    private static T _instance;

    public static T Instance
    {
        get
        {
            if (_instance == null)
            {
                _instance=FindObjectOfType<T>();
                if (_instance == null)
                {
                    //通过反射获取T类型的名字,typeof(T)就是获取T类型的信息，创建游戏对象挂载脚本
                    GameObject go = new GameObject(typeof(T).Name);
                    _instance = go.AddComponent<T>();

                    DontDestroyOnLoad(go);
                    isExisted = true;
                }
            }
            return _instance;
        }
    }
    //在子类中也可能有OnDestroy用protected修饰可以访问了，子类可能重写这个方法还要写关键字virtual成为虚方法让子类重写他
    protected virtual  void OnDestroy()
    {
        isExisted=false;
    }
}

public class YaoUIManager : SingleMonoBase<YaoUIManager>
{
   
    private YaoUIManager() { }
    public void yao()
    {
        Debug.Log("yaoyao");
    }
}}

YaoUIManager.Instance.yao();

资源加载管理器

五种方法

inspector窗口拖拽，Instantiate(go);
resources.Load方法、Resources.LoadAsync方法、Resources.LoadAll方法来加载资源。Resources文件夹只能存储2G左右的资源，要谨慎使用，不支持热更新。
AssetBundle.LoadFormXXX方法来加载资源。
Addressables(可寻址资源系统)，理解为高级的AssetBundle，资源管理由unity内部自动完成。目前还在发展中，可能有bug。
AssetDatabase.LoadAssetAtPath方法来加载资源，仅限于编辑器模式，主要用于再编辑器模式下用代码改变本地文件。
