Unity3D work log [script singleton]

The class inherits MonoBehaviour, and the script hangs on the scene object

private static ClassName mInstance;
public static ClassName GetInstance
{
    get
    {
        return mInstance;
    }
}

void Awake()
{
    mInstance = this;
}

ps:无需通过该脚本挂载的物体来获取。
错误：GameObject.Find("脚本挂载物体名称").Getcomponent<ClassName>();
正确：ClassName.GetInstance.(public方法和字段)
