[urgent]online game development

i would like to know if i hope to develop an online game, like what we play in yahoo reversi, once the user put the black peg , the oponent can see he / she put the black peg , how this would be done...any recommend site to learn the online game programming? is done by using applet , jsp or any other language.....??thanks

See my previous post:
http://forum.java.sun.com/thread.jsp?forum=406&thread=492839
The short answer is: JN_'s answer.
I was able to get this to work for myself. The applets communicate to each other through the server. I left almost all my game logic in the client, so the server basically just receives a message and forwards it to all the connected clients.

URGENT: Multiplayer Online Game

What would be the best way to make a multiplayer online game? I know how to create a game using an applet. Do I need to use a servlet? I know nothing about comunicating across the internet using java. Thanks.

no you dont need a servlet, nor an applet.. just write it. you choose servet vs. applet vs app when you ask 'how do i want them to get it?" then that helps you decide limitations of the game..
do you mind them dl'ing a client manually?
do you want it put into a web page for auto download?
do you want it to be a web page? (sorta dull dont ya think? click right to go right, click left arrow to go left.. reminds me of wumpus hunting!)
so, then you need to figure out how to communicate over a wire... advanced java networks is a good book for that.. gives a good smattering of rmi, corba, sockets, etc etc..
so once you realize sockets is the answer then go look at java.io, java.net and what not.. follow the tutorials.. ask some questions along the way and walla.. you have a simpel client/server.. after that, start writing your game.
enjoy.

What prog language/tools for a browser based online game ?

I am going to start a project for an multiplayer online game community soon, and need some advice.
The community will consist of the game itself, forum, wiki and irc-chat and use f/oss software to keep the running costs as low as possible.
The game is the heart of the community and will be a turn-based wargame with roleplaying and strategy options, mainly text based with some graphics and animations and played through a browser. (These kind of games are often referred to as Multiplayer Online RolePlaying game MORPG )
The SQL player database will have up to approx 100k player records, each of which will have many fields.
The game code will run 24/7 on a linux server (distro not chosen yet) and needs to fulfill these requirements :
easily maintanable by multiple programmers
programmers should be able to develop/test parts of the code on their own pc's using linux or windows.
good, fast access to the player DB
combat calculations will be mathemically complicated, and need to be fast
User interaction will be through a web-page
A way to keep users from accessing the game code directly to avoid computer players. (it's possible this has more to do with the code structure than with the language)
Most games of this type seem to use a php/ C combination, but that appears to have several drawbacks.
Specifically code maintainability and distinguishing between humans and bots/computer players are a problem for these games.
What environment do you think would fulfill these requirements ?
P.S. if this is to theoretical, check out these links to see some similar games :

i think java could be a good choice for the programminglanguage. Most computer have the JVM installed already...

IPad 4 online games not working properly

ever since the release of the new update, I am having difficulty connecting some game apps online. These includes Conquer online (cannot connect to game server), Injustice (online game wins not credited) and Deer Hunter 2014 (automatic updating not functioning). The issues started even before I install the update but after downloading the update. It seems like the download of data is good (CO downloads patches normally, i can manually download map updates for DH, Injustice can download the data on which I will battle) but there seems to be a problem uploading data as seen after playing Injustice where my wins are not credited.By the way, my connection is okay so the issue is really related to the update and the bug it brings. Even tried uninstalling and reinstalling apps and updating my OS to the newest to solve problem but it persists. Contacted game support groups and they are saying that app is working normally for others.

Hello geraldluigibryan,
You may consider contacting the developers of the affected games for further assistance, as you've exhausted all other potential troubleshooting steps detailed in the article below.
Contact the developer
If you see the issue again, contact the developer of the app for help:
Find the app in the App Store.
Tap the app and tap Reviews.
Tap App Support.
iOS: An app you installed unexpectedly quits, stops responding, or won’t open

Safari not allowing me to play online games

Hey all so when i try to play online games from like adult swim or any website at all none of the controls work I can't click on anything when im in the window for the game and also safari freezes up my computer. i have downloaded all the latest software updates from windows and safari and yet nothing seems to be working. Help me out please..

Safari isn't preventing you from playing any game; the game developer is doing that by only coding for Windows IE. So until they change that, you should use IE to play games, or try using the Develop menu in Safari to choose IE 6 or 7 as the User Agent to see if they will run that way.

Online games for Dreamweaver

Will DW support simple on-line games? I want to get hold of some to put onto a children's theatre website, preferably customizable and have no idea whether this is possible or where to start...

Game development is a specialty. If you have little or no game development experience, it's fair to say you probably won't pick-up these skills overnight.
FOG (Free Online Games) has a vast library of games to choose from. Just copy and paste their embed code into your HTML docs using DW Code View. Be sure to test games beforehand to ensure content and age appropriateness.

Multiplayer online Game

What I need to use to develop amultiplayer online game ..say a TicTacToe Game, 2 player can start one instance, another two play can start anathor game and so on..
Is it possible with J2SE, or I need to use J2EE?

Not even a servlet container. Could be a standalone tcp server running next to a regular webserver like Apache.
The webserver serves the applet and static html it's displayed in, applet connects to the standalone server using a custom protocol (it does need to run on the same host to be accessible of course).Yep, even that. Although I'd posit that using a servlet container would probably be simpler, and alleviate some of the more bothersome low-level networking hassle. But yep, it's worth considering.

Test my online game

Hello,
I finally managed to publish online game we developed years ago. Idea of the game is to fly with animal shaped space ship and fire opponents with different kind of guns. Game is NOT stable, so it hangs time to time, but I set my server to restart it sequentially. Game is not localized either, but I believe it's not a problem in action game, you must just test different kind of guns.
In game, first view is a hall, there you can choose your ship and three guns. You can also set your name just by typing, default name is "seppo". In bottom right there is a button with text "Aloita", that means start.
When in "battlefield" use arrow keys to move your ship and backspace/enter/right shift to fire your guns. Use esc key to go back to hall.
Please test and write some comment!
Best regards
KS

I have to say, the lag is unbearable, just when I thought the game locked up, there would be some response. The layout looks like it could work pretty good. I would really take a look at the lag. I couldnt really play the actual game due to lag.

[sos]online game

i wish to develop an online game , which is mastermind online game, one is gussing the peg another user is evaluation the pegs that correct or incorrect, i heard some one said tat should use the RMI, i am not sure, can i get some idea or recommendation? after i finish the game, where should i post to allow friends around the world can play my game simultaneously....?

actually, my lecturer want me to do this assignment by using java applet (similar to yahoo 's game)together with RMI with this way:
1. once the user log in, they are allowed to create table, then wait for the other player to join the game or invite the player from the list. (similar to yahoo reversi)the user can play as chooser or guesser, chooser is the person who decide what peg to be guess. guesser will guess the peg.(in this situation, there is a button should be provided to decide u want to sit as guesser or chooser)
2. if u are a chooser, u are able to see the answer at the bottom in order to give the black peg or white peg to the guesser. once the guesser put the color peg, chooser will evaluate it. my problem now is how the guesser will see the evaluated result once the chooser evaluate it? (how the guesser can get the updated information) and at the same time, the guesser will put the color peg, how the chooser get the updated information at the same time, both parties will see the movement?
3. how do my program serve more than one table ( each table contains two player)
thanks.

How to create a turn-based multiplayer online game?

Hello. This is my first time here. I am familiar with programming games and have been doing so for 20 years. However, I'm completely new to using Java to do so. In the past, I wrote games in BASIC, Blitz, and C++ using DirectX. Being familiar with C/C++, the Java language syntax is not a hurdle for me.
I've never created a networking game, but I feel that if I tried to create one using one of the programming languages I already know that I would succeed at doing so. (I'm just trying to show that I feel confident in programming with the languages that i know)
The dilemma here is that someone else would like me to program a turn'based multiplayer game for them in Java.
I've downloaded the NetBeans 4.1 IDE and uncovered a lot of terms and such that I'm unfamiliar with.
What I'm looking for from you guys is an overview of what I need to do to achieve my ultimate goal of creating this online game.
As a reference, I need to create a game very similar to this one:
http://www.tacticsarena.com/play/
Click on the "Launch Game: Tactics Arena Online" link to see the game.
Create a new account to play (accounts are free).
Upon starting the NetBeans IDE, I found that I could create several different types of projects. I guess first of all, I need to know what kind of project is best suited to make this type of game.
To name a few, I have to select from:
Java Application
Java Class Library (is this an Applet?)
Web Application
Enterprise Application
EJB Module
Then I guess I would like to know if any of the above projects would be used to make the clients interface or the server side software or both? Or do I need to use some other kind of software/programming language/etc. to create the server side? (As a side note, typically what kind of Operating system would the server be using? I ask because I may set one up myself for testing purposes.)
Somewhere I came upon the term 'Servlet'. Is this some kind of Java server application? Do I need/want to be using this?
As you can see, I'm very lost at where to begin. I'm not at all unfamiliar with programming. I'm just unfamiliar with Java.

Hi WolRon
I am in the process of learning Java myself and from what i have read, you have a long road ahead of you!
To start this Project the following will be essential for you to know:
Applets - if this is going to an online game
Multiple Threads - for the Server side
Swing - for the GUI on both sides
AWT - help work with the user input (mouseListeners, buttonListeners, etc)
And knowledge of a database.
those are the most obvious things that you will need to understand.
I strongly suggest buying a Java book from which you need to start at the beginning. Although the concept of OOP is the same through most languages Java has terms - as do all languages- that will be different from the other languages. Starting at the beginning will be beneficial to your Java coding future.
Good luck.

Open ports on new airport extreme to play online games

hey, i have the new airport extreme and i wanna play online games.
how do i open ports with the utily that came on disk.
i have no clue how to configure it.
i tried in bridge mode, but than the airport starts flashing amber and other users in house wanna surf on the net aswel.
kind regards

Airport Utility -> Manual setup (Cmd+L)
Internet -> NAT
Enable a default host
Then in Internet -> DHCP
permanently assign the default host IP to the machine you're going to play the games on.
This is what other routers call the "DMZ" address. Be sure to run a firewall on that machine!

Where can I find a good tutorial for mobile game developement with J2ME ?

Hi All,
I'm completely new to J2ME programming. But I have past experience on J2SE developement. Now I would like to know that where can I find a good tutorial for mobile game developement with J2ME ?
I'll be very greatful if I can find a useful step-by-step tutorial (eg. "The Java Tutorial" for J2SE)
Please point me ot the direction.
Thanks

ibook-widgets.com have a free tutorial book in the iBooks store. Search for "Create your first interactive book using iBooks Author" they also sell widgets.
I dont have any connection - I found their eBook in the store long ago and used it to learn more about iBA.
The best advice though, is be patient, go back over the process step by step, I cannot access the Help files for some reason.. but i am sure its in their.

BSOD: bad_pool_caller, while accessing Internet (youtube video, bgm, online games)

Dear all readers of this writing,
I truly want to get help or advice of solving my blue screen problem called "bad_pool_caller".
Even, I nicknamed myself as "bad_pool_caller of death" because this caused several painful experiences while playing online games. Furthermore I am just a beginner about computers, so even this small problem makes me crazy.
Let me introduce my problem and what I have done to solve this problem.
-Symptoms
this bad_pool_caller problem does not occur in offline. I found that none of problem occurs even while playing single player games over 7 hours like Far cry3 or bioshock infinite.
Only while accessing Internet, this problem occurs.
Especially, while playing any youtube videos
even also other sort of video players, almost within 20 seconds, my computer shut down by bad_pool_caller error.
and video's buffering is extremely slow.
This is not just a Internet access problem I think, because I have another my own laptop and when I play youtube video of my laptop, it plays well.
Also, when I enter a posting linked with bgm files, and try to install and play online games like starcraft 2, same things happens.
(Although the frequency is lower than that of bad poor caller, Driver IRQL Less or equal error
pops up while playing online games.
During surfing Internet without these, bad pool caller error does not happen, so I think these three things(youtube video, listening bgm, online games) have much to do with my error.
-What I have done
I tried to solve by myself after I found this link.
http://social.technet.microsoft.com/Forums/windows/en-US/e5e06b4e-6ed0-4eab-80ab-56c334f924be/windows-8-blue-screen-of-death-bsod-badpoolcaller?forum=w8itproperf
I was very happy when I found this because the situation of the writer in upper link is almost same with that of mine.
As the answer written, I format my C drive(Toshiba) and install windows 8.1 full version completely and upgraded graphic drive(GTX 760) and upgraded latetest windows 8.1 beta version upgrade of Wireless lan card drive(Netgear N900).
However, you know, still this error occurs...
-Guess the cause
I know that most bad pool caller problem arise from Hard drive and memory corruption.
But, my desktop PC is bought only a month ago and I bought quite a good SSD and HDD and Ram for playing high quality games.
So I don't think the main cause is my SSD or HDD. My graphic card is also a new one.
I suspect the cause is my network adapter, wireless lan card (USB) because this connects Internet access between my desktop PC and Louter.
I am living in University dorm and using louter using with other students together.
For getting Internet access of my desktop PC, I've bought wireless lan card (Netgear N 900) and I think this lan card causes problem such as windows 8.1 compatible
But I fully upgraded and updated lan card driver and reinstalled several times and this N900 is not bad lan card so I don't determine this is the real cause.
Here is link of my minidump record files.
https://onedrive.live.com/#cid=CF99CE81DCA9027A&id=CF99CE81DCA9027A%21943
(most error is about bad_pool_caller, but one is about Driver_IRQL_Less or Equal)
and sorry for my poor English writing skills because I am international student arrived US only 3 months. If you have some things that cannot understand of my writing, just ask me again.
Thanks for your help in advance.

Hi,
As you said,you have updated your NIC driver.
Did this issue happend when you used the wired LAN?
I think this is related to wireless driver.
I suggest that you try other wirless card to test this issue.
