Description

The NetworkManager is a convenience class for the HLAPI for managing networking systems.

For simple network applications the NetworkManager can be used to control the HLAPI. It provides simple ways to start and stop client and servers, to manage scenes, and has virtual functions that user code can use to implement handlers for network events. The NetworkManager deals with one client at a time. The example below shows a minimal network setup.

#pragma strict
public class Manager extends NetworkManager {
    public override function OnServerConnect(conn: NetworkConnection) {
        Debug.Log("OnPlayerConnected");
    }
}
using UnityEngine;
using UnityEngine.Networking;

public class Manager : NetworkManager { public override void OnServerConnect(NetworkConnection conn) { Debug.Log("OnPlayerConnected"); } }

Static Properties
