First of all, you should initialize Syncker. To do so you can simply add the following code to the AppSystemLogic class for both Master and Slave applications.首先，您应该初始化 Syncker。为此，您可以简单地将以下代码添加到 Master 和 Slave 应用程序的 AppSystemLogic 类中。

Insert the following Syncker initialization code to the AppSystemLogic::init() method:将以下 Syncker 初始化代码插入到 AppSystemLogic::init() 方法中：

In the AppWorldLogic.cpp file add the code to get the pointer to the manager and Master interface for further use in the AppWorldLogic::init() method:在 AppWorldLogic.cpp 文件中添加代码以获取指向 manager 和 Master 接口的指针，以便在 AppWorldLogic::init() 方法中进一步使用：

Objects of the following types are synchronized automatically: ObjectWaterGlobal, ObjectCloudLayer, ObjectParticles, WorldLight if they present in the *.world file on all computers.以下类型的对象会自动同步： ObjectWaterGlobal, ObjectCloudLayer, ObjectParticles, WorldLight 如果它们出现在所有计算机上的 *.world 文件中。

Synchronization of transformations is supported for all types of nodes. As for other type-specific parameters synchronization is available only for the following ones:所有类型的节点都支持转换同步。至于其他类型特定的参数同步仅适用于以下参数：

To start synchronizing other nodes or materials (the logic is the same for both), that exist in the world, you just need to tell Syncker which of them you want. To do so you can add the following code to the AppWorldLogic::init() method of your master application:要开始同步世界上存在的其他节点或材料（两者的逻辑相同），您只需要告诉 Syncker 您想要其中的哪一个。为此，您可以将以下代码添加到主应用程序的 AppWorldLogic::init() 方法中：

Now, you can implement your logic for synchronized nodes in the AppWorldLogic::update() method for Master:现在，您可以在 Master 的 AppWorldLogic::update() 方法中实现同步节点的逻辑：

You can create and delete nodes at run time. To synchronize creation of a node on all connected Slave PCs, use the createNode() function.您可以在运行时创建和删除节点。要在所有连接的 Slave PC 上同步节点的创建，请使用 createNode() 函数。

To synchronize node loading from a *.node file on all connected Slave PCs, use the loadNode() or loadNodereference() methods. This approach is recommended as it allows adding nodes of all types, unlike the createNode() method that supports only a limited number of them.要从所有连接的 Slave PC 上的 *.node 文件同步节点加载，请使用 loadNode() 或 loadNodereference() 方法。推荐使用这种方法，因为它允许添加所有类型的节点，这与仅支持有限数量的 createNode() 方法不同。

Let us consider the following simple example: we can set transformation for a node, by simply sending rotation and position via a user message.让我们考虑下面这个简单的例子：我们可以为一个节点设置变换，只需通过一个用户留言.

Next, we implement a callback function:接下来，我们实现一个回调函数：

And the last step is to set this callback using the setMessageReceivedCallback() method in AppWorldLogic::init()最后一步是使用 AppWorldLogic::init() 中的 setMessageReceivedCallback() 方法设置此回调

Run-time changes of the Global Terrain object are not synchronized automatically, but you can do it manually using custom messages:Global Terrain 对象的运行时更改不会自动同步，但您可以使用自定义消息手动进行：

You can change the viewport on the Master or Slave side. For this purpose you can use the following code (example):您可以更改 Master 或 Slave 侧的视口。为此，您可以使用以下代码（示例）：

You can also tell Slave to use another camera. To do so, you can use the following code (example):您还可以告诉 Slave 使用另一台相机。为此，您可以使用以下代码（示例）：
