[KryoNet] Client can't send and receive at the same time ?

Hi,

I’m trying to code a simple client/server using KryoNet but I’m struggling with something, my client can’t receive packets while sending.

When I hold the right key I want my player to move 1pixel to the right. In my situation when I hold the right key my player moves 1 pixel to the right, then stop moving, and finally when I release the key he literally teleports himself in the right direction. I other words the client receive almost all the packets at one time.

Here’s my code:

Client:


public void launch() throws SlickException, IOException {
		AppGameContainer container = new AppGameContainer(this);
		container.setMinimumLogicUpdateInterval(10);
		container.setMaximumLogicUpdateInterval(10);
		container.setUpdateOnlyWhenVisible(false);
		container.setAlwaysRender(true);


		client = new Client();
		ClassRegister.register(client.getKryo());
		client.addListener(new CustomListener(this));

		client.start();

		if (!connected) {
			Log.set(Log.LEVEL_TRACE);
			try {
				client.connect(5000, host, port);
				connected = true;
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		container.start();
	}

CustomListener:

@Override
	public void received (Connection connection, Object object) {
		
		if (object instanceof MoveResponse) {
			MoveResponse response = (MoveResponse) object;
			getPlayer().move(response.dir);
		}
	}

Server:

private void start() throws IOException {
		server = new Server();
		ClassRegister.register(server.getKryo());
		server.bind(port);
		server.addListener(new ServerListener(this));
		server.start();
		Log.set(Log.LEVEL_TRACE);
	}

ServerListener:

@Override
	public void received(Connection connection, Object object) {
                if (object instanceof MoveRequest) {
			MoveRequest request = (MoveRequest) object;
			
			MoveResponse response = new MoveResponse();
			response.dir = request.dir;
			connection.sendTCP(response);
		}
	}

Input:



public void update() {
		movePlayer();
	}

private void movePlayer() {
		if (pressedRight) {
			sendMoveRequest(3);
		} else if (pressedUp) {
			sendMoveRequest(1);
		} else if (pressedDown) {
			sendMoveRequest(2);
		} else if (pressedLeft) {
			sendMoveRequest(4);
		}
	}

	public void keyPressed(int key, char c) {
		if(key == goDown) {
			pressedDown = true;
		} else if(key == goLeft) {
			pressedLeft = true;
		} else if(key == goUp) {
			pressedUp = true;
		} else if(key == goRight) {
			pressedRight = true;
		}
	}

	public void keyReleased(int key, char c) {
		if(key == goDown) {
			pressedDown = false;
		} else if(key == goLeft) {
			pressedLeft = false;
		} else if(key == goUp) {
			pressedUp = false;
		} else if(key == goRight) {
			pressedRight = false;
		}
	}

I seriously don’t see where I’m messing up :frowning: Any help?
