    Pack images into .jar file?

    Thanks! I guess i will do that, since jPong isn't a game one would play on a LAN-Party. I thought about creating a game-lobby, where one can download the games and directly connect to other players, but that will take a while.
  2. I already replaced the line with a bar, its in the new release with the bugfix.
  3. Thank you guys so much! I just moved the "setSize();" after the swing stuff, its now working 100% for me. launcherPanel.add(startButtonServer); this.add(launcherPanel); this.setSize(200,151); /** * Connect as Client The speed is currently increasing on every contact with a paddle, but i want to manipulate the direction of the ball depending on the position on the paddel where it collides. I think i am going to put 20 hours or more into it, to make it a real nice game (better graphics, higher performance, better networking, and of course fixing every little bug) To extend it, i am thinking of adding a list of recent servers for quick-connect, Bonus Items (in- or decrease paddle Size, gravitation,...)
  4. Ok, thanks for the feedback i am sorry for that, it worked most of the time for me... Here is the Code for the launcher: package jPong_multi; import java.awt.Dimension; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.IOException; import java.io.InputStream; import javax.imageio.ImageIO; import javax.swing.*; /** * * @author Michael Langeder * */ public class Launcher extends JFrame implements ActionListener{ /** * */ private static final long serialVersionUID = 1L; /** * Launcher für JPong */ public static void main(String[] args) { // TODO Auto-generated method stub new Launcher(); try { //load Ball String Pathl1 = "img/ball2.png"; InputStream streaml1 = JPong.class.getResourceAsStream(Pathl1); JPong.img_ball = ImageIO.read(streaml1); JPong.ballR=JPong.img_ball.getWidth(); //load Cursor1 String Pathl2 = "img/cursor.png"; InputStream streaml2 = JPong.class.getResourceAsStream(Pathl2); JPong.img_cursor = ImageIO.read(streaml2); //load Cursor2 String Pathl3 = "img/cursor2.png"; InputStream streaml3 = JPong.class.getResourceAsStream(Pathl3); JPong.img_cursor2 = ImageIO.read(streaml3); } catch (IOException e) { System.out.println("At least 1 Picture could not be opened!"); JPong.run=false; } catch (IllegalArgumentException e){ System.out.println("A Picture has not been loaded!"); JPong.run=false; } catch (NullPointerException e){ System.out.println("Could not get size of ball!"); JPong.run=false; } } public Launcher(){ //initialize window properties this.setTitle("jPong Launcher"); this.setSize(200,150); this.setVisible(true); //create elements JPanel launcherPanel = new JPanel(); JLabel launcherLabel = new JLabel(); JButton startButtonClient = new JButton("Connect to Host"); JButton startButtonServer = new JButton("Host Game"); final JTextField adressLine = new JTextField("Type Server IP"); adressLine.setPreferredSize(new Dimension(100,20)); //attach elements launcherPanel.add(launcherLabel); launcherPanel.add(adressLine); launcherPanel.add(startButtonClient); launcherPanel.add(startButtonServer); this.add(launcherPanel); /** * Connect as Client */ startButtonClient.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent e) { String adresse = adressLine.getText(); new JPong(adresse); setVisible(false); } }); /** * Connect as Client */ adressLine.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent e) { String adresse = adressLine.getText(); new JPong(adresse); setVisible(false); } }); /** * start Server and connect as Client */ startButtonServer.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent e) { new Server(); new JPong("localhost"); setVisible(false); } }); } @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub } } I hope someone can tell me where the problem is Thanks already!
  5. This is a bug, that i am already aware of. It helps to restart the launcher a few times or use a different JRE version
  6. Hey folks, I am working on a little game called jPong, and i would really like to get some feedback from you! Here's the Link: http://www.langeder.org/wordpress/games/jpong/ It is not finished yet, but already playable in multiplayer. Please note that there is a bug when starting the launcher, which will just open a blank window. This can be fixed by restarting the launcher a few times. So far it took me around 20 hours to make it. Thanks!

    Pack images into .jar file?

    Thank you so much! It works, but i had to make a folder inside the Class, not inside src Here is a dl, i would appreciate some feedback! http://www.langeder.org/wordpress/jpong-version-1-1-released-multiplayer-launcher/

    Pack images into .jar file?

    Thanks for the answer! I hope this will solve my problem!
  9. Hello everyone! I just started learning Java and i use eclipse. At the moment i work on a Pong game and i want to include some pictures i.e. a ball instead of a circle, to make it look better. This is the Code i use to load the image: try { img_ball = ImageIO.read(new File("/home/michael/Desktop/workspace-java/JPong/src/ball2.png")); } catch (IOException e) { System.out.println("ball2.png not found!"); } As you can see i use absolute paths, because relative would not work at all. But using absolute paths is not what i want since i'm not the only to playing it. Where do i have to place those files to be accessible relatively? I would also like to put it INTO the jar file, so the release is just one file to run without the folders with files Thanks in advance!

    Networking to Slow - Java Multiplayer Pong

    Ok, I will try to implement that. Kaptein, Thank you for your advices and all the informations! PsychoticRabbit: But it will only affect the CPU time, not network itself that much i guess?

    Networking to Slow - Java Multiplayer Pong

    So i should let the Clients kinda estimate where the ball will be on the next update? Or insert an interpolated point between two of the updates?

    Networking to Slow - Java Multiplayer Pong

    You mean not to send single lines with auto-flush?

    Networking to Slow - Java Multiplayer Pong

    Thank you so much! I added it and its much better now Is there anything else i can do?
  14. Hey all! I created a Pong Game in Java and added Networking, but it seems to slow the whole game down signifficantly. I use a thread for the networking routine, on both server and the two clients. The conversion is as follows: send a marker (so the receiver knows which value will be sent next) send the value send the next marker, etc... This is the Code for the Server: /** * * Klasse (Thread) welche die Netzwerkfunktionen abhandelt * */ class Network implements Runnable { Network() { } public void run() { // mit Host verbinden und Kommunizieren try { ServerSocket server = new ServerSocket(8888); System.out.println("Warte auf Verbindung auf Port 8888"); Socket Client1 = server.accept(); System.out.println("Server: Client1 verbunden"); Socket Client2 = server.accept(); System.out.println("Server: Client2 verbunden"); //Client1 einrichten OutputStream out1 = Client1.getOutputStream(); PrintStream ps1 = new PrintStream(out1, true); // Second param: auto-flush on write = true InputStream in1 = Client1.getInputStream(); BufferedReader br1 = new BufferedReader(new InputStreamReader(in1)); //Client2 einrichten OutputStream out2 = Client2.getOutputStream(); PrintStream ps2 = new PrintStream(out2, true); // Second param: auto-flush on write = true InputStream in2 = Client2.getInputStream(); BufferedReader br2 = new BufferedReader(new InputStreamReader(in2)); String line=""; ps1.println("run"); ps2.println("run"); while(true){ //Einlesen Client1 for(int i=0;i<1;i++){ line = br1.readLine(); if(line!=null){ if(line.contains("v1")){ line = br1.readLine(); player1Y=Integer.parseInt(line); } } }//end Einlesen for-Schleife //Einlesen Client2 for(int i=0;i<1;i++){ line = br2.readLine(); if(line!=null){ if(line.contains("v1")){ line = br2.readLine(); player2Y=Integer.parseInt(line); } } }//end Einlesen for-Schleife //Ausgabe an Client1 ps1.println("v2"); ps1.println(""+player2Y); ps1.println("v4"); ps1.println(""+ballY); ps1.println("v3"); ps1.println(""+ballX); ps1.println("v5"); ps1.println(""+player1Score); ps1.println("v6"); ps1.println(""+player2Score); //Ausgabe an Client2 ps2.println("v2"); //gespiegelt für Player 2 ps2.println(""+player1Y); ps2.println("v4"); ps2.println(""+ballY); ps2.println("v3"); ball2X=MAXX-ballX; //gespiegelt für Player2 ps2.println(""+ball2X); ps2.println("v5"); //gespiegelt für Player2 ps2.println(""+player2Score); ps2.println("v6"); //gespiegelt für Player2 ps2.println(""+player1Score); } } catch (IOException e) { // TODO Auto-generated catch block //e.printStackTrace(); System.out.println("Verbindungsfehler aufgetreten"); } } } And the Client: /** * * Klasse (Thread) welche die Netzwerkfunktionen abhandelt * */ class Network implements Runnable { String hostAdress; Network(String adress) { this.hostAdress = adress; } public void run() { try { Socket connectionToTheServer = new Socket(hostAdress, 8888); System.out.println("Client: Verbindung zu Server hergestellt"); InputStream in = connectionToTheServer.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(in)); OutputStream out = connectionToTheServer.getOutputStream(); PrintStream ps = new PrintStream(out, true); String line=""; while(!(line.equals("run"))){line=br.readLine();}//warten auf Start des Spiels while(true){ //Ausgeben ps.println("v1"); ps.println(""+player1Y); //Einlesen for(int i=0;i<5;i++){ line = br.readLine(); if(line!=null){ if(line.contains("v2")){ line = br.readLine(); player2Y=Integer.parseInt(line); }else if(line.equals("v3")){ line = br.readLine(); ballX=Double.parseDouble(line); }else if(line.equals("v4")){ line = br.readLine(); ballY=Double.parseDouble(line); }else if(line.contains("v5")){ line = br.readLine(); player1Score=Integer.parseInt(line); }else if(line.contains("v6")){ line = br.readLine(); player2Score=Integer.parseInt(line); } } }//end Einlesen for-Schleife } } catch (UnknownHostException e) { // TODO Auto-generated catch block //e.printStackTrace(); System.out.println("Verbindungsfehler aufgetreten"); } catch (IOException e) { // TODO Auto-generated catch block //e.printStackTrace(); System.out.println("Verbindungsfehler aufgetreten"); } } Logically everything works fine, but its very slow. I would appreciate some recommendations on how to improve the speed! Thanks in advance!
