您好我正在使用Kryonet作为我正在开发的游戏的网络库。
我在服务器端有这个代码:
public class MyServer {
Kryo kryo;
Server server;
Connection connection;
public MyServer(){
server = new Server();
server.start();
try {
server.bind(59990, 59900);
} catch (IOException e) {
System.out.println("FATAL ERROR");
}
kryo = server.getKryo();
kryo.register(Message.class);
server.addListener(new Listener() {
public void received (Connection con, Message str) {
System.out.println("Message recieved from client to server");
Message m = (Message)str;
System.out.println(m.text);
}
public void connected(Connection con){
System.out.println("Hey, we are connected!");
connection = con;
con.sendTCP("HOLA CLIENTE!!");
}
public void disconnected(Connection con){
System.out.println(":( He is gone... he'll never come back..");
}
});
}
public void sendMessage(String tipoMensaje,String tipoTropa,String id){
connection.sendTCP(tipoMensaje+"-"+tipoTropa+"-"+id);
}
}
这在客户端:
public class MyClient {
Client client;
Connection connection;
Kryo kryo;
public MyClient(){
client = new Client();
client.start();
try {
kryo = client.getKryo();
kryo.register(Message.class);
client.connect(5000, "10.211.55.3", 59990, 59900);
//sendMessage("fromclient","ee","ee");
client.addListener(new Listener() {
public void received (Connection con, String str) {
System.out.println(str);
System.out.println("Message recieved from server to client");
}
public void connected(Connection con){
System.out.println("Hey, we are connected!");
connection = con;
Message m = new Message();
m.text="eeep";
client.sendTCP(m);
}
public void disconnected(Connection con){
System.out.println(":( He is gone... he'll never come back..");
}
});
} catch (IOException e) {
System.out.println("Error while connecting");
}
}
public void sendMessage(String tipoMensaje,String tipoTropa,String id){
client.sendTCP(tipoMensaje+"-"+tipoTropa+"-"+id);
System.out.println("Message sent from client to server");
}
}
消息只是一个包含字符串的类。当我尝试将客户端连接到服务器时,我得到了“嘿,我们已经连接了!”消息,然后在服务器的命令行中收到“从客户端收到消息”的消息。但是,m.text(消息的内容)没有打印,我不知道为什么。
提前致谢。
答案 0 :(得分:3)
这是因为监听器中没有方法public void received (Connection con, String str)
- 基本上,您的服务器从不调用它。这也是您应该使用@Override
的原因 - 您首先不会遇到此问题。
将String str
替换为Object o
。然后 - 检查您的对象实际上是否为Message
。如果是,请将其转换为Message
并打印出其文本。您的方法应如下所示:
@Override
public void received(Connection connection, Object packet) {
if (packet instanceof Message) {
System.out.println(((Message) packet).text);
}
}
