本節提供了與網路系統一起使用的組件的詳細資料。

3、NetworkClient

        NetworkClient 是一個 HLAPI 類，管理網路連接到伺服器 — — 對應著 UNET NetworkServer。它可以用於將訊息發送到伺服器和從伺服器接收訊息。NetworkClient 還可以協助管理衍生的網路對象和 RPC 訊息和網路事件的路由。

Properties

Property:		Function:
serverIP		The IP address of the server that this client is connected to.
serverPort		The port of the server that this client is connected to.
connection		The NetworkConnection object this client is using.
handlers		The set of registered message handler functions.
numChannels		The number of configured NetworkTransport QoS channels.
isConnected		True if the client is connected to a server.
allClients		List of active network clients (static).
active		True if any network clients are active (static).

4、NetworkConnection

NetworkConnection是一個 HLAPI 類，封裝了網路連接。NetworkClient 對象具有一個NetworkConnections，和 NetworkServers 有多個NetworkConnections------來自每個用戶端。   網路連接已能發送位元組數組，或序列化的對象作為 網路訊息。

Properties

Property:		Function:
hostId		The NetworkTransport hostId for this connection.
connectionId		The NetworkTransport connectionId for this connection.
isReady		Flag to control whether state updates are sent to this client.
address		The IP address of the end-point that this connection is connected to.
playerControllers		The set of players that have been added with AddPlayer().

5、NetworkIdentity

          NetworkIdentity 組件是Unity 組件，它是 新網路系統的核心 。它可以被添加到對象。從-AddComponents->Network->NetworkIdentity 功能表項目 。此組件控制對象的網路標識。這表明 NetworkIdentity 組件在一個對象上如下所示:

與Unity Network System的 伺服器權威系統，網路的對象的NetworkIdentities 必須是由伺服器使用 NetworkServer.Spawn()所  “spawned” 。這會導致他們被分配NetworkInstanceId，在串連到伺服器的用戶端上建立。

        情境物體比動態執行個體化對象有點區別對待。這些對象是全部  出現在用戶端和伺服器上的情境中。然而，當建設遊戲 的所有情境對象的identities 將被都禁用。當用戶端串連到伺服器時，伺服器將通知用戶端應啟用哪些情境對象 和其最新的狀態資訊是通過 spawn 訊息。這可確保用戶端將不會包含對象放置在現在不正確的位置，當他開始playing，或 甚至對象會立即被刪除串連因為一些事件中移除他們之前用戶端串連。"ServerOnly"  複選框將確保這某一特定對象不會催生了或在用戶端上啟用。

        此組件包含像什麼情境 ID，網路識別碼 和 資產 ID 已指派給對象的跟蹤資訊。情境 ID 是一個在 NetworkIdentity 組件的所有情境物體中有效。網路識別碼 是此特定對象執行個體的 ID，可能有多個對象的特定物件類型的執行個體化和  網路識別碼 用於的標識的對象，例如，網路更新應適用。資產 ID 是指什麼源資產對象被執行個體化。這是內部使用，當特定對象預置被網路spawned 。此資訊被公開的預覽面板底部的Inspector:

     在運行時是要在此處顯示的詳細資料 (disabled  NetworkBehaviour 顯示 非粗體):

Properties

Property:		Function:
netId		A unique identifier for this network session, assigned when spawned.
sceneId		A unique identifier for networked objects in a scene. This is only populated in play-mode.
isClient		True if this object is running on a client.
isServer		True if this object is running on the server, and has been spawned.
hasAuthority		True if this object is the authoritative version of the object. So either on a the server, or on the client with localPlayerAuthority.
localPlayerAuthority		True if this object is controlled by the client that owns it - the local player object on that client has authority over it. This is used by other components such as NetworkTransform.
serverOnly		A flag to make this object not be spawned on clients.
assetId		This identifies the prefab associated with this object (for spawning).
playerControllerId		The identifier of the controller associated with this object. Only valid for player objects.
observers		The list of client NetworkConnections that are able to see this object. This is read-only.

Hints

• Put a NetworkIdentity component on prefabs that will be spawned.
• A NetworkIdentity is required for every object that is networked.
