我使用kryonet来处理网络上与游戏的数据交换。 但我不知道为什么TCP套接字和UDP套接字变为非阻塞。
所以我很乐意得到一些帮助。
我有一个服务器类和一个客户端类。
package com.me.mygdxgame;
import java.io.IOException;
import com.esotericsoftware.kryo.Kryo;
import com.esotericsoftware.kryonet.Connection;
import com.esotericsoftware.kryonet.Listener;
import com.esotericsoftware.kryonet.Server;
public class Serveur {
private static Serveur instance;
private World world;
private WorldController controller;
private GameScreen hoteScreen;
private boolean leftPressedHote = false;
private boolean rightPressedHote = false;
private boolean leftPressedClient = false;
private boolean rightPressedClient = false;
private Server serveur;
private boolean connected = false;
private Serveur() {
serveur = new Server();
Kryo kryo = serveur.getKryo();
kryo.register(KeyInfo.class);
kryo.register(World.class);
serveur.addListener(new Listener(){
public void connected(Connection connection) {
Serveur.getInstance().setConnected(true);
}
public void received (Connection connection, Object object) {
if (object instanceof KeyInfo) {
Serveur.getInstance().setKeyInfo((KeyInfo) object);
connection.sendTCP(Serveur.getInstance().getWorld());
}
}
public void disconnected(Connection connection) {
ClientThread.getInstance().setConnected(false);
}
});
}
public void initialize(GameScreen hote) {
world = new World();
controller = new WorldController(world);
this.hoteScreen = hote;
hoteScreen.setWorld(world);
}
public void start() throws IOException {
serveur.start();
serveur.bind(54555, 54777);
}
public void stop() {
serveur.stop();
Serveur.instance = null;
}
这是客户端代码：
package com.me.mygdxgame;
import java.io.IOException;
import java.net.InetAddress;
import com.esotericsoftware.kryo.Kryo;
import com.esotericsoftware.kryonet.Client;
import com.esotericsoftware.kryonet.Connection;
import com.esotericsoftware.kryonet.Listener;
import com.esotericsoftware.kryonet.Listener.ThreadedListener;
import com.esotericsoftware.minlog.Log;
public class ClientThread {
private Client client;
private GameScreen gameScreen;
private static ClientThread instance;
private boolean connected = false;
public static ClientThread getInstance() {
if (instance == null) {
instance = new ClientThread();
}
return instance;
}
public ClientThread() {
Log.set(Log.LEVEL_TRACE);
client = new Client();
client.start();
Kryo kryo = client.getKryo();
kryo.register(World.class);
kryo.register(KeyInfo.class);
client.addListener(new Listener() {
public void connected(Connection connection) {
ClientThread.getInstance().setConnected(true);
}
public void received(Connection connection, Object object) {
if (object instanceof World) {
World world = (World) object;
ClientThread.getInstance().getGameScreen().setWorld(world);
}
}
public void disconnected(Connection connection) {
ClientThread.getInstance().setConnected(false);
}
});
}
public boolean connectToServer() {
InetAddress address = client.discoverHost(54777, 5000);
if (address != null) {
try {
client.connect(5000, address, 54555, 54777);
} catch (IOException e) {
e.printStackTrace();
return false;
}
return true;
}
return false;
}
public void stop() {
client.stop();
ClientThread.instance = null;
}
public void sendKeyInfo(KeyInfo info) {
client.sendTCP(info);
}
这是我在客户端LogCat上的日志：

答案 0 :(得分：0)
从Kryonet API的外观来看，例如：写队列，它在内部使用非阻塞套接字通道。
