（对于新项目，应使用 5.1 版中引入的新网络系统。此信息适用于使用旧网络系统的旧版项目。）
网络视图是通过网络来共享数据的主要组件。这些视图允许两种类型的网络通信：__状态同步 (State Synchronization)__ 和__远程过程调用 (Remote Procedure Calls)__。
网络视图会监视特定对象以检测更改。然后将这些更改共享给网络上的其他客户端，以确保所有客户端都了解状态更改。此概念称为_状态同步_，可在状态同步页面了解更多有关此概念的信息。
在某些情况下，您不希望承担在客户端之间同步状态的开销，例如，在发送新对象或重生玩家的位置时。由于此类事件很少发生，因此同步所涉及对象的状态是没有意义的。相反，可以使用_远程过程调用_来告诉客户端或服务器执行这样的操作。可以在 RPC 手册页找到关于远程过程调用的更多信息。
网络视图通过其 __NetworkViewID__（基本上就是在网络机器之间协商的唯一标识符）在网络中标识身份。此标识符表示为 128 位数字，但如果可能，在通过网络传输时会自动压缩到 16 位。
到达客户端的每个数据包都需要应用于 NetworkViewID 指定的特定网络视图。使用这种方式，Unity 可以找到正确的网络视图，解压缩数据，并将传入的数据包应用于网络视图的观察对象。
有关在 Editor 中使用网络视图的更多详细信息，请参阅网络视图组件参考页面。
如果使用 Network.Instantiate() 创建联网对象，则无需担心分配网络视图和自行适当分配它们的问题。全部都将在幕后自动完成。
但是，您可以使用 Network.AllocateViewID 手动设置每个网络视图的 NetworkViewID 值。脚本参考文档举例说明了如何使用 RPC 函数在每个客户端上手动实例化对象，然后使用 AllocateViewID 手动设置 NetworkViewID。
