copied!<p>I have recently downloaded some simple game code off a online tutorial. I am currently trying to make it multiplayer. However in my portion of the program where the coordinates are written to a socket the variables don't update. I have searched all over the internet looking fro an answer but I have found none. I have tested the code and the Ints get sent successfully.</p> <p>My Client.java</p> <pre><code>import java.net.*; import java.util.Scanner; import java.io.*; import javax.swing.SwingUtilities; public class Client implements Runnable{ public void run() { Craft crObj = new Craft(); int playerX = 3001; int playerY = 300; String serverName = "127.0.0.1"; int port = 6789; int port1 = 6788; Socket client = null, client1 = null; System.out.println("Connecting to " + serverName + " on port " + port); OutputStream outsetup = null, out1setup = null; try { client = new Socket(serverName, port); client1 = new Socket(serverName, port1); } catch (IOException e) { System.out.println(e); } System.out.println("Connected"); Scanner test = new Scanner(System.in); try { outsetup = client.getOutputStream(); out1setup = client1.getOutputStream(); } catch(IOException e) { System.out.println(e); } DataOutputStream out = new DataOutputStream(outsetup); DataOutputStream out1 = new DataOutputStream(out1setup); while(true) { try { //Doesn't Update Here playerX = crObj.getX(); playerY = crObj.getY(); out.writeInt(playerX); out.flush(); out1.writeInt(playerY); out1.flush(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } </code></pre> <p>My Craft.java</p> <pre><code>import java.awt.Image; import java.awt.event.KeyEvent; import javax.swing.ImageIcon; public class Craft { private String craft = "craft.png"; Client clObj = new Client(); public int dx; public int dy; public int x; public int y; private Image image; public ImageIcon ii; public Craft() { ImageIcon ii = new ImageIcon(this.getClass().getResource(craft)); image = ii.getImage(); x = 40; y = 60; } public void move() { x += dx; y += dy; } public int getX() { return x; } public int getY() { return y; } public Image getImage() { return image; } public void keyPressed(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = -2; ii = new ImageIcon(this.getClass().getResource("craftBACK.png")); image = ii.getImage(); } if (key == KeyEvent.VK_RIGHT) { dx = 2; ii = new ImageIcon(this.getClass().getResource("craft.png")); image = ii.getImage(); } if (key == KeyEvent.VK_UP) { dy = -2; ii = new ImageIcon(this.getClass().getResource("craftUP.png")); image = ii.getImage(); } if (key == KeyEvent.VK_DOWN) { dy = 2; ii = new ImageIcon(this.getClass().getResource("craftDOWN.png")); image = ii.getImage(); } } public void keyReleased(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = 0; } if (key == KeyEvent.VK_RIGHT) { dx = 0; } if (key == KeyEvent.VK_UP) { dy = 0; } if (key == KeyEvent.VK_DOWN) { dy = 0; } } } </code></pre> <p>Board.java</p> <pre><code>import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Toolkit; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyAdapter; import java.awt.event.KeyEvent; import javax.swing.JPanel; import javax.swing.Timer; public class Board extends JPanel implements ActionListener { public int xMain = 0; Client clObj = new Client(); private Timer timer; private Craft craft; public Board() { addKeyListener(new TAdapter()); setFocusable(true); setBackground(Color.BLACK); setDoubleBuffered(true); craft = new Craft(); timer = new Timer(5, this); timer.start(); } public void paint(Graphics g) { super.paint(g); Graphics2D g2d = (Graphics2D)g; g2d.drawImage(craft.getImage(), craft.getX(), craft.getY(), this); Toolkit.getDefaultToolkit().sync(); g.dispose(); } public void actionPerformed(ActionEvent e) { craft.move(); xMain = craft.getX(); System.out.println(xMain); repaint(); } private class TAdapter extends KeyAdapter { public void keyReleased(KeyEvent e) { craft.keyReleased(e); } public void keyPressed(KeyEvent e) { craft.keyPressed(e); } } } </code></pre> <p>RType.java</p> <pre><code>import javax.swing.JFrame; public class RType extends JFrame { public RType() { add(new Board()); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(400, 300); setLocationRelativeTo(null); setTitle("R - Type"); setResizable(false); setVisible(true); (new Thread(new Client())).start(); } public static void main(String[] args) { new RType(); } } </code></pre>
