继承单例基类就不用再写了

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。
