的项目的解决方案。这个项目包含一些基本类，然后是我的域对象被抽象的所有接口。接口如MudEngine.Core和IWorld。
IRealm我还有一个名为public interface IWorld : IGameComponent, ICloneableComponent<IWorld>
{
/// <summary>
/// Gets how many hours it takes to complete one full day in this world.
/// </summary>
int HoursPerDay { get; }
/// <summary>
/// Gets or sets the game day to real hour ratio.
/// </summary>
double GameDayToRealHourRatio { get; set; }
/// <summary>
/// Adds a collection of realms to world, initializing them as they are added.
/// </summary>
/// <param name="realms">The realms.</param>
/// <returns>
/// Returns an awaitable Task
/// </returns>
IRealm[] GetRealmsInWorld();
/// <summary>
/// Initializes and then adds the given realm to this world instance.
/// </summary>
/// <param name="realm">The realm to add.</param>
/// <returns>Returns an awaitable Task</returns>
Task AddRealmToWorld(IRealm realm);
/// <summary>
/// Creates and initializes a new instance of a realm.
/// </summary>
/// <param name="name">The name of the realm.</param>
/// <param name="owner">The world that owns this realm.</param>
/// <returns>Returns an initialized instance of IRealm</returns>
Task<IRealm> CreateRealm(string name, IWorld owner);
/// <summary>
/// Adds a collection of realms to world, initializing them as they are added.
/// </summary>
/// <param name="realms">The realms.</param>
/// <returns>Returns an awaitable Task</returns>
Task AddRealmsToWorld(IEnumerable<IRealm> realms);
/// <summary>
/// Removes the given realm from this world instance, deleting the realm in the process.
/// If it must be reused, you may clone the realm and add the clone to another world.
/// </summary>
/// <param name="realm">The realm to remove.</param>
/// <returns>Returns an awaitable Task</returns>
Task RemoveRealmFromWorld(IRealm realm);
/// <summary>
/// Removes a collection of realms from this world instance.
/// If any of the realms don't exist in the world, they will be ignored.
/// The realms will be deleted during the process.
/// If they must be reused, you may clone the realm and add the clone to another world.
/// </summary>
/// <param name="realms">The realms collection.</param>
/// <returns>Returns an awaitable Task</returns>
Task RemoveRealmsFromWorld(IEnumerable<IRealm> realms);
}
的项目，它是所有接口的默认实现。
MudEngine.Mud项目包含我工厂的接口。像MudEngine.Core和IWorldFactory这样的工厂。 IWorld接口有一个创建方法，它使用给定的IRealmFactory来创建领域并返回它们。
IRealmFactory当我在IWorld界面上调用/// <summary>
/// Provides methods for creating an instance of an IRealm implementation
/// </summary>
public interface IRealmFactory
{
/// <summary>
/// Creates and initializes a new instance of a realm.
/// </summary>
/// <param name="name">The name of the realm.</param>
/// <param name="owner">The world that owns this realm.</param>
/// <returns>Returns an initialized instance of IRealm</returns>
Task<IRealm> CreateRealm(string name, IWorld owner);
/// <summary>
/// Creates and initializes a new instance of a realm.
/// </summary>
/// <param name="name">The name of the realm.</param>
/// <param name="owner">The world that owns this realm.</param>
/// <param name="timeZoneOffset">The time zone offset to apply to the realm.</param>
/// <returns>Returns an initialized instance of IRealm</returns>
Task<IRealm> CreateRealm(string name, IWorld owner, ITimeOfDay timeZoneOffset);
/// <summary>
/// Creates and initializes a new instance of a realm.
/// All of the children zones will be initialized prior to being added to the realm.
/// </summary>
/// <param name="name">The name of the realm.</param>
/// <param name="owner">The world that owns this realm.</param>
/// <param name="zones">A collection of zones that will be initialized and added to the realm.</param>
/// <returns>Returns an initialized instance of IRealm</returns>
Task<IRealm> CreateRealm(string name, IWorld owner, IEnumerable<IZone> zones);
/// <summary>
/// Creates and initializes a new instance of a realm.
/// All of the children zones will be initialized prior to being added to the realm.
/// </summary>
/// <param name="name">The name of the realm.</param>
/// <param name="owner">The world that owns this realm.</param>
/// <param name="timeZoneOffset">The time zone offset to apply to the realm.</param>
/// <param name="zones">A collection of zones that will be initialized and added to the realm.</param>
/// <returns>Returns an initialized instance of IRealm</returns>
Task<IRealm> CreateRealm(string name, IWorld owner, ITimeOfDay timeZoneOffset, IEnumerable<IZone> zones);
}
时，实现使用IRealmFactory来创建它。工厂通过IWorld实现的构造函数传递。
我现在的问题是，工厂实施应该在哪里？包含域接口实现的同一项目是否通常为工厂提供实现，或者消耗层（例如表示/单元测试项目）是否负责实现工厂并使用它们？
目的是根据您正在构建的基于文本的游戏的类型，可以换出这些组件。所以我倾向于实现具有自己工厂的接口的每个包。我关心的是DI设置。进一步在分层（服务器/客户端应用程序）中的IoC容器需要知道它应该使用每个包中的哪个工厂，而不是仅使用在IoC容器所属的消耗层中定义的工厂。 / p>
有没有关于此的行业标准指南？
答案 0 :(得分：0)
您似乎正在尝试使用抽象的子域构建域模型（我猜您可以将它们称为子域，因为它们是完整的游戏系统），即用户可以在运行时动态选择子域，从而触发一些子域不可知行为，然后用它做一些特定于子域的东西一段时间，并在它们完成时跳转到另一个。
虽然根据我的经验，你很少在“正常”的商业项目中遇到这个问题，但这就是我要做的事情：
为通用的World和Realm管理创建一个总体有界上下文。将IWorld和IRealmFactory放在那里。
为每个游戏系统子域创建一个单独的Bounded Context。它们可以是整个项目，也可以只是命名空间。在这些中编写IRealmFactory的实现。
我认为使用Container.Resolve(...)时的少数几个实例之一可能是合法的。在IoC配置中创建命名注册，并随时解析其中一个注册，以连接对应于一个游戏系统的对象子图。
