Unity之NetWork创建与连接服务器
- Network.InitializeServer(int connettions,int Port,bool useNat)：该函数用于初始化服务器。Connections是最大连接数, Port是服务器监听的端口号,useNat表明是否使用Nat穿透。返回枚举类型NetworkConnectionError。返回NetworkConnectionError.NoError时表示创建服务器成功，没有错误。
- Network.Connect(string IP,int Port)：该函数用于连接服务器。IP是所要连接的服务器的IP地址，Port是端口号。返回枚举类型NetworkConnectionError。返回NetworkConnetionError.NoError是表示连接服务器成功，没有错误。
- Network.Disconnect()：关闭所有开放的连接并关闭网络接口。
- Network.connections：所有连接的玩家
- OnPlayerConnected(NetworkPlayer player)：当一个新玩家成功连接时在服务器调用
- OnPlayerDisconnected(NetworkPlayer player)：当一个玩家从服务器上断开时在服务器端调用
- OnConnectedToServer()：当成功连接到服务器时，在客户端调用这个函数。
- OnDisconnectedFromServer(NetworkDisconnection msg)：服务器上连接已经断开时，在客户端调用这个函数，但当连接已经被禁用，也会在服务器上调用。
