在线信标

在线信标 为客户端与服务器之间的通信提供了一种轻量级机制，避免了使用普通虚幻引擎（UE）网络游戏连接的必要。在线信标由Actor类派生而来，提供了一种基础框架。你可以在派生类中扩展该框架，从而让这些类执行特定于项目的交互和信息请求。在线信标的常见用例包括：

• 计算连接ping。

• 预订游戏会话的位置。

• 在加入游戏前查询游戏会话或大厅的信息。

通常情况下，Actor的复制和生成由权威服务器发起。由于服务器通常具有权威性，客户端必须先连接到服务器，才能获得由服务器管理的Actor副本。在线信标的工作方式与此不同，它为客户端提供了创建Actor的系统，让Actor与服务器建立联系，然后发起委托，从而让服务器信标在客户端连接后立即发起远程程序调用（RPC）。

类结构

在线信标框架含有以下结构：

• AActor
  • AOnlineBeacon
    • AOnlineBeaconHost
    • AOnlineBeaconClient
  • AOnlineBeaconHostObject

在线信标

在线信标是 AOnlineBeaconClient 和 AOnlineBeaconHost 的基类。通常不需要重载在线信标本身，因为你可以单独重载在线信标客户端和在线信标主机。

在线信标客户端

在线信标客户端是客户端实现据以派生的基类。它也是在线信标系统的主要工作类。

该类自带 UNetDriver ，用于发起与服务器的连接。一旦客户端和服务器的在线信标客户端对象副本之间建立了连接，对象的复制体的行为就将和同普通的UE复制体一致。服务器和客户端都可以调用RPC，并且服务器的在线信标客户端对象对属性复制体具有更大权限。

通常你应该在客户端Gameplay代码中生成一个在线信标客户端，然后使用 AnlineBeaconClient::InitClient 函数连接到位于服务器的在线信标主机。你需要为在线信标主机对象构造函数指定你所用的在线信标客户端类，这样服务器才能知道要生成哪个客户端类与客户端设备通信。你可以重载 AOnlineBeaconClient::OnConnected 函数，以便在服务器和客户端建立连接后立即调用RPC。你还可以重载 AOnlineBeaconClient::OnFailure 函数来执行自定义的故障处理机制。

在线信标主机

在线信标主机是主机用来管理客户端所有信标连接的基类。在线信标主机将管理在线信标主机对象的注册表，从而根据当前正在请求连接并与在线信标主机通信的在线信标客户端类型引导流量。

该类自带UNetDriver，用于监听来自客户端的连接。当在线信标主机收到来自远程设备在线信标客户端的连接时，主机会扫描它的在线信标主机对象实例注册表，以确定与呼入客户端相匹配的对象，然后将连接的管理权移交给该在线信标主机对象。

通常你应该在服务器Gameplay代码中生成在线信标主机，例如在游戏模式类中。

在线信标主机对象

在线信标主机对象是所有负责处理来自在线信标客户端流量的主机类的基类。

该类会在服务器上生成相应的在线信标客户端，以匹配发起连接的客户设备上的在线信标客户端。在线信标主机对象使用 ClientBeaconActorClass 成员变量来确定要生成何种在线信标客户端类的Actor。

当你生成在线信标主机后，你通常应该在服务器Gameplay代码中生成一个在线信标主机对象，然后将该在线信标主机对象注册到在线信标主机上。一旦在线信标客户端连接到委托发起的在线信标主机对象，就会调用 AOnlineBeaconHostObject::OnClientConnected 函数。然后你就可以在此函数内调用RPC来发起客户端与主机之间的通信。

引擎示例

虚幻引擎在头文件 TestBeaconClient.h 和 TestBeaconHost.h 中提供了小型的在线信标实现，其目录如下：

• ..\Engine\Plugins\Online\OnlineSubsystemUtils\Source\OnlineSubsystemUtils\Classes\

该实现被包含在相关的 .cpp 文件中，文件目录如下：

• ..\Engine\Plugins\Online\OnlineSubsystemUtils\Source\OnlineSubsystemUtils\Private\

测试信标实现会在服务器和客户端之间来回反复调用RPC，并每次打印一条简短的日志信息。下方小节将介绍如何在Gameplay代码中生成测试信标。

生成测试信标

要在项目中使用 TestBeaconClient 和 TestBeaconHost 类，请执行以下步骤：

1. 在你的服务器Gameplay代码中生成一个 ATestBeaconHost 。

2. 在你的客户端Gameplay代码中生成一个 ATestBeaconClient 。

3. 在客户端Gameplay代码中调用 ATestBeaconClient::InitClient(url) ，将客户端连接到服务器，其中 url 是包含服务器地址和端口的 FURL 对象。

一旦点击 开始游戏（Begin Play） ，你的Gameplay代码就会在服务器上生成一个测试信标主机，并在每个客户端上生成一个测试信标客户端。下文小节将介绍因此在测试信标之间自动产生的进程流。

测试信标进程流

本节介绍游戏开始时生成测试信标后的进程流：

• 首先 ATestBeaconHost 构造函数会将成员变量 ClientBeaconActorClass 设置为类 ATestBeaconClient，并将成员变量 BeaconTypeName 设置为 ClientBeaconActorClass->GetName() 。这将确保在线信标系统将测试信标主机和测试信标客户端的类配对在一起，从而让服务器生成正确的客户端类，与发起连接的客户端类相匹配。

• 当客户端设备的 ATestBeaconClient 对象与服务器联系时，服务器的 AOnlineBeaconHost 实例将指示已注册的 ATestBeaconHost 生成自身的 ATestBeaconClient，并将其与客户端设备上的 ATestBeaconClient 关联。如此一来，客户端设备上就有一个测试信标客户端，服务器设备上也有一个测试信标客户端。此外，网络连接还有助于客户端和服务器RPC在两个 ATestBeaconClient 实例之间传递信息。

• 接下来，服务器的 ATestBeaconHost 会调用 ATestBeaconHost::OnClientConnected 。在函数 ATestBeaconHost::OnClientConnected 中，服务器的测试信标客户端实例通过调用客户端RPC ClientPing 发起ping。

• 当客户端设备的 ATestBeaconClient 实例接收到RPC并执行 ATestBeaconClient::ClientPing_Implementation 时，客户端的测试信标客户端会首先在客户端日志中打印 LogBeacon: Ping ，然后调用服务器RPC ServerPong 。

• 最后，当服务器设备的 ATestBeaconClient 实例接收到RPC并执行 ATestBeaconClient::ServerPong_Validate 函数时，服务器会验证程序是否在发布配置中运行。如果验证成功，则执行 ATestBeaconClient::ServerPong_Implementation 。在函数 ATestBeaconClient::ServerPong_Implementation 中，服务器的信标客户端会首先在服务器日志中打印 LogBeacon: Pong ，然后调用客户端RPC ClientPing 。这样调用 ClientPing 会导致上一句点和这一句点发生重复。

这一过程会无限延续，并提供一个在线信标实现的示例，供你根据项目需求在此基础上进行扩展。

如果要在一次来回后停止这一流程，可以删除 ATestBeaconClient::ServerPong_Implementation 中对 ClientPing 的调用。

除本引擎示例外，本文档还在下文的实现在线信标小节列出了在线信标的逐步实现指南。

引擎配置

要在你的项目中使用在线信标，你首先必须对其进行配置。有几种引擎配置选项可供选择。

要配置在线信标，请将以下内容添加到项目的DefaultEngine.ini文件中：

	[/Script/Engine.Engine]
	+NetDriverDefinitions=(DefName="BeaconNetDriver",DriverClassName="/Script/OnlineSubsystemUtils.IpNetDriver",DriverClassNameFallback="/Script/OnlineSubsystemUtils.IpNetDriver")

	[/Script/OnlineSubsystemUtils.OnlineBeacon]
	BeaconConnectionInitialTimeout=30.0
	BeaconConnectionTimeout=45.0

	;[/Script/OnlineSubsystemUtils.OnlineBeaconClient]
	;BeaconConnectionInitialTimeout=
	;BeaconConnectionTimeout=

	[/Script/OnlineSubsystemUtils.OnlineBeaconHost]
	ListenPort=8888
	bReuseAddressAndPort=false
	bAuthRequired=false
	MaxAuthTokenSize=1024
Copy full snippet

[/Script/Engine.Engine] +NetDriverDefinitions=(DefName="BeaconNetDriver",DriverClassName="/Script/OnlineSubsystemUtils.IpNetDriver",DriverClassNameFallback="/Script/OnlineSubsystemUtils.IpNetDriver") [/Script/OnlineSubsystemUtils.OnlineBeacon] BeaconConnectionInitialTimeout=30.0 BeaconConnectionTimeout=45.0 ;[/Script/OnlineSubsystemUtils.OnlineBeaconClient] ;BeaconConnectionInitialTimeout= ;BeaconConnectionTimeout= [/Script/OnlineSubsystemUtils.OnlineBeaconHost] ListenPort=8888 bReuseAddressAndPort=false bAuthRequired=false MaxAuthTokenSize=1024

配置参考

本节将解释上述各个配置选项的用途，以及如何为你的项目配置这些选项。

引擎

以下内容将配置信标网络驱动程序，以驱动在线信标的网络流量：

	[/Script/Engine.Engine]
	+NetDriverDefinitions=(DefName="BeaconNetDriver",DriverClassName="/Script/OnlineSubsystemUtils.IpNetDriver",DriverClassNameFallback="/Script/OnlineSubsystemUtils.IpNetDriver")
Copy full snippet

[/Script/Engine.Engine] +NetDriverDefinitions=(DefName="BeaconNetDriver",DriverClassName="/Script/OnlineSubsystemUtils.IpNetDriver",DriverClassNameFallback="/Script/OnlineSubsystemUtils.IpNetDriver")

本例使用 IpNetDriver 作为网络驱动程序的类。要使用不同的网络驱动程序类，请在 DriverClassName 字段中指定要使用的类。

在线信标

在线信标客户端

在线信标主机

请确保在线信标主机所配置的监听端口（Listen Port）与在 FURL 对象中传递给在线信标客户端 InitClient 函数的端口一致。

实现在线信标

本节包含一个在线信标的示例实现，用于计算服务器-客户端ping的往返时间（RTT）。往返时间是指数据包从客户端发送到服务器，再返回客户端所需的时间。本示例只是一个小型实现，仅仅简单介绍了在线信标的功能，但其目的是提供一个可用的示例，帮助你上手测试信标以外功能的实现，并解释如何在Gameplay代码中设置在线信标。

本在线信标示例由C++和蓝图共同实现，利用UE的反射系统函数元数据说明符和类元数据说明符进行远程程序调用，并将特定函数公开给蓝图可视化脚本。

要使用虚幻引擎的在线信标执行ping程序，请执行以下步骤：

1. 创建或打开虚幻引擎C++项目。

2. 使用C++类向导创建三个新的C++ 类：

   • 从 OnlineBeaconClient 派生的名为 PingClient 的类。

   • 从 OnlineBeaconHost 派生的名为 PingHost 的类。

   • 从 OnlineBeaconHostObject 派生的名为 PingHostObject 的类。

3. 将Ping信标代码小节的代码添加到相应的头文件和源文件中：

   • Ping客户端代码

   • Ping主机代码

   • Ping主机对象代码

4. 将以下函数添加到你项目的游戏模式文件：

Header

	public:	
		bool InitPingBeacon();
Copy full snippet

public: bool InitPingBeacon();

Source

	bool ABeaconsGameMode::InitPingBeacon()
	{
		ENetMode Mode = GetNetMode();
		if (Mode == NM_DedicatedServer || Mode == NM_ListenServer)
		{
			APingHost* Host = GetWorld()->SpawnActor<APingHost>(APingHost::StaticClass());
			if (Host && Host->InitializeHost())
			{
				APingHostObject* HostObject = GetWorld()->SpawnActor<APingHostObject>(APingHostObject::StaticClass());
				if (HostObject)
				{
					Host->RegisterHostObject(HostObject);
					return true;
				}
			}
		}
		return false;
	}
Copy full snippet

bool ABeaconsGameMode::InitPingBeacon() { ENetMode Mode = GetNetMode(); if (Mode == NM_DedicatedServer || Mode == NM_ListenServer) { APingHost* Host = GetWorld()->SpawnActor<APingHost>(APingHost::StaticClass()); if (Host && Host->InitializeHost()) { APingHostObject* HostObject = GetWorld()->SpawnActor<APingHostObject>(APingHostObject::StaticClass()); if (HostObject) { Host->RegisterHostObject(HostObject); return true; } } } return false; }

1. 在你游戏模式的 BeginPlay 函数中调用 InitPingBeacon 。

2. 在你项目的 DefaultEngine.ini 文件中添加引擎配置小节中的配置，由此确保已将项目配置为使用在线信标。

3. 将以下内容添加到只在客户端游戏实例内运行的蓝图中。本示例使用第三人称模板，因此本代码被添加到 BP_ThirdPersonCharacter 中：

测试你的在线信标实现

要测试你的在线信标实现，你必须使用专用服务器或监听服务器以及至少一个单机客户端来运行项目。无需使用 open 控制台命令将客户端连接到服务器。这是在线信标的主要功能，客户可以发起与服务器的联系，然后通过快速操作断开连接。

要测试你的在线信标实现，请执行以下操作：

1. 确保已成功编译项目。

2. 在虚幻编辑器中打开你的项目。

3. 找到 编辑器偏好设置（Editor Preferences） ，将 关卡编辑器（Level Editor） > 运行（Play） 设置如下：

   • 找到 按单机游戏运行（Play in Standalone Game） ：

     • 将 额外启动参数（Additional Launch Parameters） 设置为 -WINDOWED -ResX=800 -ResY=640 -log 。

   • 找到 多人游戏选项（Multiplayer Options） ：

     • 启用 启动单独服务器（Launch Separate Server） 。

     • 将 联网运行（Play Net Mode） 设置为 单机运行（Play Standalone） 。

     • 禁用 在一个进程下运行（Run Under One Process） 。

     • 将 额外服务器启动参数（Additional Server Launch Parameters） 设置为 -log 。

   点击查看大图。

4. 点击 运行（Play） 。你应该看到三个新窗口出现：服务器日志窗口、客户端日志窗口和客户端游戏实例。

5. 如果在客户端日志窗口中看到以下行，则表示ping信标成功：

            LogPingClient: Ping Complete: 29 ms
   Copy full snippet

   LogPingClient: Ping Complete: 29 ms

   实际的毫秒数可能有所不同。

调试

如果在客户端日志窗口中未看到以上行，则表示ping信标很可能不成功。如果ping信标不成功，请检查以下内容。

端口

确保客户端在线信标指定的端口与引擎配置中的服务器在线信标指定的端口一致。

	[/Script/OnlineSubsystemUtils.OnlineBeaconHost]
	ListenPort=8888
Copy full snippet

[/Script/OnlineSubsystemUtils.OnlineBeaconHost] ListenPort=8888

网络驱动程序

确保服务器创建了网络驱动程序，以监听此指定端口。

	LogNet: IpNetDriver_1 IpNetDriver_1 IpNetDriver listening on port 8888
Copy full snippet

LogNet: IpNetDriver_1 IpNetDriver_1 IpNetDriver listening on port 8888

如果在日志中没有看到像上方那样指定端口的行，请参阅上文的引擎配置小节。

日志记录

在线信标使用 LogBeacon 日志类别记录所有在线信标的网络流量。LogNet 和 LogHandshake 这类额外日志类别也可用于调试在线信标。
