I have to make the connect 4 game be connect 3. Ive edited a code but I the math is over my head. These loop methods check the ways someone can win.
for (int j=0;j<7;j+=2)//need to change
{
if ((f[i][j+1] != " ")
&& (f[i][j+3] != " ")
&& (f[i][j+5] != " ")
&& (f[i][j+7] != " ")
&& ((f[i][j+1] == f[i][j+3])
&& (f[i][j+3] == f[i][j+5])
&& (f[i][j+5] == f[i][j+7])))
//end of loop

So I am trying to create a Multi-Player game in java, and I have a Game server and a Client. They normally connect with either but I would like to add a login server so that there can be an option to go to a different world then just the main one. It will have the same map and data but will be separate from the Players that are on world one per say. Now if you are on world two I would like it to have the option for you to be able to Private message players that are on World one. That is where the login server comes in to play.
I am still new at Java and would like to be able to understand Packets and how to handle them more clearly. So far I have gotten the basis of the login server connected to the server and the client connects to the server via the login server. But I am getting a bunch of "unhandled packets" and I would like to know how to handle them. Here are some bits of the code.
package com.ls.net;
import org.jboss.netty.channel.ChannelHandlerContext;
import org.jboss.netty.channel.ChannelStateEvent;
import org.jboss.netty.channel.ExceptionEvent;
import org.jboss.netty.channel.MessageEvent;
import org.jboss.netty.channel.SimpleChannelUpstreamHandler;
[Code] ....
So when I run my client this pops up in the console:
[Tue Sep 16 16:50:56 EDT 2014][LoginServer]: Finished initializing login server.
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 15
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 41
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 74
[Code] ....
And here are the class's for Accounts:
package com.ls.net.codec.decoder.packets;
import org.jboss.netty.buffer.ChannelBuffer;
import org.jboss.netty.channel.ChannelHandlerContext;
import com.ls.bufutils.BufferUtils;
import com.ls.net.codec.decoder.PacketDecoder;

I created a simple Hangman game. It functions correctly, the only issue is when the file contains a phrase (2 or more words), spaces are not displayed when the program is run. For example, if the phrase was Java Programming Forums.
It would appear as _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.
I want there to be spaces in between the words. How could I fix this? What would I need to add to my code?
import java.util.Scanner;
import java.io.*;
public class hangman{
public static void main (String[] args) throws FileNotFoundException{
Scanner kb = new Scanner(System.in);
String guess;
String guesses = "";
int wrongGuess = 8;

I have compiled and coded the whole thing, but the TIE function when no one wins, isn't popping up. I'm not sure why but here is my code;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;

The TIE doesn't pop up, that is all the errors i have, though there is no error messages.
Our assignment is to make a version of the classic 'Connect Four' game, where we need to construct a GUI that shows the current state of the game and instead of having a winner once a player has four chips in a row, the game needs to continue until no chips can be placed anymore.We currently get stuck in the GUI part. Running it right now results in a board with empty spaces only. Also after choosing a column to place, the board remains empty.
Our question: How do we get the board filled with the right color of chips at the right place?We know the 'ArcsPanel'-class (almost at the bottom of the code) is wrong, but we don't know what to do to make it right.
Main class 'ConnectPanel':
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.GridLayout;
[code]....
At the moment, only the colors white, red and blue are used. This is purely for finding out how to work in general.
I am trying to make a java Simon game but I cannot figure out how to make the GUI work. I have this so far, but now it just keeps saying I lose and it isn't functioning. It seems the only way I can make it work is having the action listeners in the do loop, but then once a button is clicked, the code errors out.
import java.awt.Color;
import java.awt.event.ActionEvent;

I am doing an assignment in my Java class and I need to connect the nodes to make a 12 pointed star. I have already drawn out the star and figured out which nodes to connect together. The only thing I cannot get is to show all of the nodes in the order they connect. I can only get the first 3 nodes to show up. I need it to wrap around and basically keep adding 5 to the last node until all numbers 0-11 are used.
public class StarWinding {
public static void main(String[] args) {
for (int i = 0 ; i < 12; i+=5) {
System.out.print(i + " ");
}
}
}
And the out put so far is: 0 5 10
I need it to be: 0 5 10 3 8 1 6 11 4 9 2 7
I am a student in an intro to computer science class working on my final project. This is essentially a game of connect 4, but only requiring 3-in-a-row for victory.

Here is an example of a GUI. Is it possible to make this kind of a thing using Java Swing? Is it possible to have a picture on the entire background of the JFrame, and then other Swing components like buttons, labels etc. sitting on it?Is it possible to have action listeners behind pictures? In other words, they will behave like buttons: the user clicks on them and they do something.
View Replies View RelatedIs there a way to connect the popupmenu to the right Object (JFrame).
(Something like SwingUtilities.getWindowAncestor(popupmenu)
I've created 2 JFrames each with the same MouseClass. When you click on the RMB a pop menu is shown with a background item. When clicked on the background item only the last created JFrame changes his background.
Below is my simplified code. I'm probably not thinking like a good OO'er.

I have been practicing writing java code, my university course is going to cover socket programming and multi-threading.
I am presently just starting to write myself a framework for all multiplayer games I may make in the future, my aim really is simply to practice and understand better and this time, im not using an ide, just sublime text, all new grounds for me, I have a good basic understanding of the subject but I want to be fluent.

I am pretty basic when it comes to java programming. i think the last thing i learned was if, repeat, random and boolean statements. the thing i want to do as a big project in java is make a 2D sandbox game with a title page and everything.
View Replies View RelatedI wanted to know which RAD TOOL should I use to make the grid. I used the label but it's not interesting like the game *. I m starting to make the game and can't think how to make the grid.
Thought of using the buttons but can't add image to it.
what should I use to make the grid.
* what I did earlier Is place 9 label in grid form (just to test) and nine buttons one for each. When u click a button, image is shown in respective label... But it doesn't feel like u r playing game..
Firstly, my code is just a demo of my multiplayer game (2 or more players can play simultaneously) to demonstrate my problem without any extra things. I have successfully implemented peer-to-peer (P2P) communication in my game. Later, I decided to add support for client-server communication (ie a central server which is also a player) in my game. It should be much easier than P2P. Now here is the problem:
Suppose, I have 1 server and some clients (may be 1 or more clients). They all should give the following output:
Starting...
A
B
C
E
F
...
...
Done!
They all give the above output without using multi-thread. But using multi-threading, it gives the above output only when there're 1 server and 1 client. I'm using 2 threads (1 for sending, 1 for receiving) for each Socket. That means, each client has only 2 threads for communication but the server has (2 * totalClients) threads.
I've attached my full test project. So, here I'm only showing my 2 thread classes.
ReceiveThread class:
class ReceiveThread extends Thread {
private ObjectInputStream receiveStream;
private BlockingQueue<Character> queue = new ArrayBlockingQueue<Character>(Common.totalClients);
[Code] ....
Since I've attached my full test project, I'm not showing the other 3 classes. They are ServerMain, ClientMain and Common. If I've 2 clients to be connected, then I get the following output:
Server: (Runs first)
Starting...
A
Client 1 (clientID is 1): (Runs after the server)
Starting...
A
B
B
Client 2 (clientID is 2): (Runs after Client 1)
Starting...
A
They are stuck at there, even no exception. Actually, the server and the clients are stuck at the line try { ch = queue.take(); } if more than 1 client are connected. It seems that all are trying to receive data. But without using the dedicated threads, they all work as expected even for more than 1 client. Why is this behaviour? How to solve it? Note that I have used the same SendThread and ReceiveThread classes by which I have succcessfully implemented P2P communication.
About my attached test project file:
It has 5 small .java files for the classes as stated above. It is currently faulty when using additional threads. You have to change clientID variable for each client (they are described inside). But it works as expected without additional threads. To test it without the additional threads:
Comment " TODO" linesUncomment the single lines just after " TODO" linesComment the additional thread construction lines (4 lines)
Currently, for a workaround, I'm not using the dedicated threads for sending and receiving data only for client-server communication in my multi-player game. But I'm still using these threads for P2P communication. I don't know why it is and how to solve it.This is the attached test project file as described above.

View Replies View RelatedI currently have the code set up to iterate through objects and keep track of them but how do I do the same and draw the objects on the panel window? I'm confused on what to do and how to start it.
Here's the code I have so far, the 'Car' which I want to draw extends to another class which extends to GameObject. I currently have a 'draw()' method under the 'Car' class but nothing in the 'draw()' method yet. From what I understand i'm suppose to have a 'draw()' method under 'GameObjects' class also?
public class MapView extends JPanel implements IObserver, ActionListener{
JPanel myPanel;
private Timer timer = new Timer(5, this);
int x = 0;
int moveX = 2;
public MapView(){
super.setBorder(BorderFactory.createTitledBorder("Map:"));

Mostly I don't understand how to go through the iterator again to paint the objects. Wouldn't I need to put another iterator under 'paintComponent()' or can it be done under 'update()' ?
how to get some shapes from the GameObjects onto my panel.
I've created a chat program, but now I need to show messages in different colors depending if the message is received or sent. I was wondering if I can use jlabel to do this but in this case I need that jlabels to scroll in a jpanel. how to do this or maybe using a rtf ?
