我在玩多人游戏时遇到问题。现在,我只是想让服务器将当前级别发送到客户端。服务器肯定会发送数据,但它永远不会到达客户端应用程序。
客户端代码:
public void run() {
while(true)
{
try {
sel.select();
Set readyKeys = sel.selectedKeys();
Iterator itr = readyKeys.iterator();
while(itr.hasNext())
{
SelectionKey key = (SelectionKey) itr.next();
itr.remove();
SocketChannel ch = (SocketChannel) key.channel();
if(key.isReadable())
{
inputbuf.clear();
long bytesRead = ch.read(inputbuf);
inputbuf.flip();
byte[] test = inputbuf.array();
{
for(int i=0; i < inputbuf.remaining(); i++)
{
System.out.print(test[i]+" ");
}
}
byte cmd = 0;
cmd = inputbuf.get();
switch(cmd)
{
case 1:
//do something
case 2:
//do something else
break;
}
}
else if(key.isConnectable())
{
sc.finishConnect();
sc.register(sel, SelectionKey.OP_READ);
}
}
} catch (IOException ex) {
Buildsim.error("Error handling input from server", ex);
}
}
}
服务器代码:
public RemotePlayer(SocketChannel s)
{
sc = s;
try {
sel = Selector.open();
sc.configureBlocking(false);
sc.register(sel, SelectionKey.OP_WRITE);
socket = sc.socket();
ip = socket.getInetAddress().toString();
System.out.println("New connection from "+ip);
inputbuf = ByteBuffer.allocate(1048576);
outputbuf = ByteBuffer.allocate(1048576);
inputbuf.clear();
outputbuf.clear();
}
catch(Exception e)
{
Buildsim.error("Connection error: ", e);
}
sendLevel();
}
public void sendObject(GameObject obj)
{
//Sends a packet of the object, then does the same for the object's children
}
public void sendLevel()
{
try {
outputbuf.put((byte) 0x01);
outputbuf.flip();
sc.write(outputbuf);
sendObject(Buildsim.w.parts.get(0)); //root object
}
catch(IOException e)
{
Buildsim.error("Error sending level to "+ip, e);
}
}
唯一到达客户端的是字节 0x01(表示电平变化)。
提前致谢。
