This section provides detailed information about components used with network systems.

3. NetworkClient

NetworkClient is a HLAPI class that connects the Management Network to the server-corresponds to the UNET NetworkServer. It can be used to send messages to the server and receive messages from the server. NetworkClient can also help manage derived network objects and RPC messages and route network events.

Properties

Property:		Function:
ServerIP		The IP address of the server that this client is connected.
ServerPort		The port of the server that this client is connected.
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 is a HLAPI class that encapsulates network connections. The NetworkClient object has one NetworkConnections, and NetworkServers has multiple NetworkConnections ------ From each client. The network connection can send byte arrays or serialized objects as network messages.

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.
PlayerControllers		The set of players that have been added with AddPlayer ().

5. NetworkIdentity

The NetworkIdentity component is the Unity component and is the core of the new network system. It can be added to an object. Choose-AddComponents-> Network-> NetworkIdentity. The network ID of the control object of this component. This indicates that the NetworkIdentity component is shown as follows on an object:

The NetworkIdentities of Network objects must be "spawned" by the server using NetworkServer. Spawn ". This causes them to be assigned NetworkInstanceId and created on the Client Connected to the server.

Scene objects are slightly different from dynamic instantiated objects. All these objects appear on the client and server. However, the identities of all scenario objects for game construction will be disabled. When the client is connected to the server, the server will notify the client which scenario objects and their latest status information should be enabled through spawn messages. This ensures that the client will not include the object placed in the current incorrect location, when it starts playing, or even the object will be immediately deleted from the connection because some events remove them before the client connection. The "ServerOnly" check box ensures that a specific object is not generated or enabled on the client.

This component contains the trace information such as the scenario ID, network ID, and asset ID that has been assigned to the object. The scenario ID is valid in all scenario objects of the NetworkIdentity component. Network ID is the ID of this specific object instance. There may be multiple objects of specific object type instantiation and network ID used for the identification of objects. For example, network update should apply. Asset ID refers to the source asset object that is instantiated. This is internally used when a specific object is preset by the Network spawned. Inspector at the bottom of the preview panel where this information is exposed:

The detailed information to be displayed here during running (disabled NetworkBehaviour is not in bold ):

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 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.
