语法：

network_create_server(type, port, max_client);

返回： Real（实数）

描述

This function is used to create a new network server for your game, using one of the permitted connection protocols (see the constants listed below). You supply the server type, then give it a port to use, and finally the number of maximum connections that should be permitted at any one time to the server (note that this number is up to you, but too many connected clients will saturate the network or the device CPU won�t be able to handle the processing of that number of players, so use with care). The function returns a unique id which should be used stored in a variable and used to identify the server in all further network functions, or a value of less than 0 if the connection fails.

例如：

var port = 6510;
server = network_create_server(network_socket_tcp, port, 32);
while (server < 0 && port < 65535)
   {
   port++
   server = network_create_server(network_socket_tcp, port, 32);
   }

上述代码将会尝试使用TCP协议通过端口6510创建一个服务端。若端口不可用，则会遍历所有端口并找到合适的进行连接。
