Web turn based game - lines of action

Hi,
I'm trying to build simple web lines of action with jsp. i already have a game engine which i'm going to use in a bean
my problem is that i want the user to see message "please wait - thinking" while the computer is thinking on the next move and after the computer finished calculating the next move to send it to the user. and now the user could enter his next move from a textline.
thanks

It sounds like the applet is a self-contained program, serving up to 4 players, and not communicating with a separate server or clients. This would imply that your single applet instance owns and maintains the game state model.
If you want to move to a multi-instance game, you have two choices. Either peer-to-peer, and you can do without server altogether if you want to, or client/server, and you need a server. Both have pros and cons, but usually the client/server model is superior, it is also by far the most common. For applets it may actually be the only choice due to security restrictions, but I�m not an applet expert. Both of these distributed models require a rethink on your part regarding the game state model. If it�s a big rethink or not depends on your game and your ambition. Basic questions/issues can be:
* Do all clients/instances see all state information?
* Do you need persistance (e.g. save game, crash recovery)?
* How do instances connect to each other/to the server?
* Which instances may manage the game (accept/throw out players, terminate the game, etc)
* Perhaps the most important: How is the consistency of state information ensured between the instances?
(A note on your other question: servlets are server-side java programs that generate HTML-pages to be sent to the browser, similar to PHP and ASP. They have nothing directly to do with applet technology.)

I am developing turn based game but it does not clear the badge number

Currently i am developing turn based game and i get notifications for new game if someone invite me but i unable to clear these badge number . Is there any one who can suggest me how to clear badge number's for turn based game in objective c ?

HI
As per my understanding of your issue, there are 2 ways.. one is what u are trying...in this way first ensure your item have proper canvas setup. Or try to display the canvas without using button. If this work, then there should not be problem.
Second way of doing is ..
Using TAB Canvas. You put all your 'MYBLOCK' data on TAB PAGE(2ND PAGE), ....AND in when buttong pressed, u just use go_block...will complete your job without much effect.
If any issue, post here..

Implementing a turn-based game

Hi,
I am implementing a turn based game but am having problems coding the actual turns of the players.
I have thought maybe:
Player[] players = {player1, player2, player3, player4 etc }
while(there is no winner) {
    players[1].haveGo();
    players[2].haveGo();
    players[3].haveGo();
    players[4].haveGo();
}Is this a good way of implementing a turn based game or is there a default way which is considered good practise?
Many thanks
Cath

Hi Cath
The pseudo code you've included is wrong because the loop will be completed even if one of the players is finished the game. it's have to be like this .
while(there is no winner)
     players[1].haveGo();
     if (there is no winner) players[2].haveGo();
     if (there is no winner) players[3].haveGo();
     if (there is no winner) players[4].haveGo();

Help needed with Multiplayer/Network aspect of a turn-based game.

Hello,
I've converted a turn-based 4-player board game into a nicely working JApplet. Everything works fine, however, I'm stuck in "Hot Seat" mode. I need to get this working for multiple clients, but I'm not sure how to do this.
Can I use a servlet that the clients connect to to share data? The machine is running a webserver but I don't have access to the startup scripts. Can I launch the servlet manually?
If a servlet won't work, I am familiar with c/c++ socket programming. Should I just create a Java server to handle the exchange? I'm guessing applets can't connect to a server, so I'd have to convert the JAppet to an application, true?
Please give me an idea what the best mechanism to exchange data would be, and I'll follow that trail.

2 player turn based game logic in c# for snake and ladder

Hello programmers,
I am developing a snake and ladder game in xaml and C#.(windows 8.1 app)
my question is:
1) I am unable to think about the solution for player turn, I have build the game logic for single player and its working fine. please provide some solutions or the concept.
2) I have build the same game logic with two different ways, one with nested if else and the next with array which one would be good for performance.
and I also want to know about windows Azure for online score and multi player game service.

Hi,
I am not very familiar with the multiplayer Game development. For multiplayer games, you'll need to set up a matchmaking server and have the clients connect to it. It can then pair them off and facilitate communications. If the clients have publicly available
network addresses then it can introduce them and they can talk directly to each other.There isn't anything built in for this so you'll need to either build your own or find a third party implementation. If you are using Unity3d then check out
http://docs.unity3d.com/Documentation/Components/net-MasterServer.html
Also, you can use Xbox services, and I find an article below:
https://msdn.microsoft.com/en-us/library/bb975801.aspx
For windows Azure problem, you should go to windows Azure forum.

Game Center with multi-player games/ turn based

Hi All
I seem to have a problem with the concept of the Game Center and exactly what it's supposed to do. If I am being a thicky, please tell me!!
My Wife has an Ipad, my daughter an Ipad mini, son has an Iphone 4S and I have just bought a macbook pro. I have just started to work away and thought it would be a great family thing to play games against each other but this games center doesn't seem to be for this! I have added all 3 of them as friends on the center and thats about all I can do!
When I goto the 'my games' on my pro, it says I dont have any games and I can download them from the app store, when I click the link, I get a blank screen come up with no games.
When I goto ITunes and try to download a multiplayer turn based game it downloads but I cant do anything with it (I did this with scrabble, a hang man game and Uno).
Are all these different hardware types incompatable to each other with game center?
How do I get games on there?
Are there any real time turn based games that will fullfill what I want? I have a go, then one of my family members does the same, even though we may have to wait a few hours to do the next turn. It doesnt have to be all 4 of us, maybe run 3 games at once with myself against each of my family.
Thankyou in advance
Andy

Your family can play each other by purchasing the app on their own devices – but you'll be left out. There is a difference between buying apps from the iTunes Store and using the App Store on your Macbook Pro (known as the Mac App Store).

Best way to implement a countdown timer for a turn based LCCS game

Hello,
I am trying to build a turn based game and sketching out the high level map, so I can focus my efforts towards the direction I should be digging.
One thing I have not seen much in the sample apps is how a turn based game is best handled.
For example, a countdown timer. Should it be a shared property? Or a Baton which is supposed to manage workflows and has a timeout property?
Or, should I forget those two, and time this on the server, although if it would become popular keeping track of all the times in the rooms would cost an arm and leg. Would love to hear some best practices on this.

good idea.
Which one or all of them?

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.

Web-Based Game Skill System

Hello everyone,
I am currently developing a web-based game website using
Coldfusion 8 and MS SQL.
Until recentely, things have been going well. But I am now
stuck on a small issue of using an in-game skill system.
The way it works (or will work) is that your in-game
character will have a large library of skills to choose from, all
of which are accessible throughout the entire game. By choosing a
skill, your character will begin learning it over a set amount of
time (the time required for that specific skill). Your character
will, over time, generate it's own library of learnt skills - each
benefiting him or her within the game.
I hope this is all clear so far :)
So my small (but actually quite large) issue is that I'm not
sure how to go about storing this list of learnt skills.
My first instinct was to create a column within the
"characters" table in which the learnt skills would be stored as a
list, and then drawn out when actually listed on a page. But I have
heard that using lists within database tables isn't such a good
idea, and I would generally prefer another way around the issue.
My next idea was to create a table listing all of the
available skills as columns (a kind of library of every in-game
skill), then the characters would have a single row in that table
in which they have a "yes" or "no" under each skill column. These
yes or no answers would then be used to generate the library of
skills that character has. But this idea is very messy and I don't
even know how I could use this table in an SQL query...
I'd really like a simple and powerful solution for this
issue/problem, and I would be highly appreciative of anyone that
could help me!
Thanks in advance,
Aiden

"Thanks a lot for your reply anyway :) and I'm sorry it
wasn't of use
to me."
Actually Dan was guiding you down the correct database
normalization
path. What you have is a classic many-to-many join. You have
many
character records and many skill records and you want to join
them such
that a character can have 0-N skills (zero to infinity) and a
skill can
be used by 0-N players.
This is done with three tables. A character table with the
basic
details of a character and a skills table with the details of
the skills
and a joining table that connects the two. At a minimum the
join tables
simple consists of two fields, a foreign key field to the
characters
table and a foreign key field to the skills table. Thus for
each skill
a character has there will be one record connecting the two
id's
together. This joining table can easily be expanded to have
other data
about the character-skill join such as when it started, what
level the
character has reached in the skill, whatever else your system
needs.
An simple Example:
Character Table
ID Name
1 Joe
2 Sam
3 George
Skill Table
ID Name
1 Hunting
2 Cooking
3 Archery
Character_Skill Join Table
CharID SkillID
1 1
1 3
2 2
3 1
3 2
3 3
Thus with basic SQL join syntax we can synthesize the data
that Joe can
hunt and shoot arrows, Sam can cook and George can do it all.

Web based Game

Hi Friends.
I want to design a web based game. There is a server and two clients. Each client is a player and the server will handle the collaboration between them. I am using Netbeans and jsp.
First client one will type the url of server and gets connected. Then it has to wait until second client connects. When second client also connects, then I should update the browser window contents of client one. How can I do this?
If you did not get the quesiton, please e-mail me at [email protected] I shall explain you more clearly. Please help me at your best.
Thanks.

A server cannot push to the client, but you can use AJAX to poll to the server.
Mailing is meaningless. If you feel you have more to explain, just post it here at the dicsussion forum. It's not a contact advertising forum.

Dealing with a turn based application with using a global static variable

Hi there. I read some articles about JavaFX concurrency,so as a newbie i have to practice on it. Now i'm trying to implement a turn based application that can be played among 3-6 players. Moreover, i use a scene imported from a .fxml file and i have to update it correctly depends on some calculations of each thread (in other word players ). My main issue is, i don't wanna use a while loop which checks the state of game like;
while( GameState != State.GAME_OVER ){
     currentPlayer = GameBoard.getNextPlayer();
     // do some actions,calculations etc.
So, i want to use worker threads instead of this while loop. I guess using Service class for iterating and assigning the next player will be suitable instead of using the while loop and Tasks for doing each player's calculation,or waiting for some responses from Human players on UI based,however, i'm struggling with two problems.
There should a global static variable ( like GameState which is an Enumarator ) determines the state of the game,so it should be updated and should be checked by each turn. Is there any way to do this ?
How can i get rid off this while loop ?
I will appreciate for every answer. Thanks anyway.

It shouldn't make too much difference. The basic idea is that you have a model class representing your game state (the Game class in jsmith's example). When a player makes a move, you update the state of the game. Since this will result in changes to the UI, this update should be performed on the FX Application Thread.
If the player making the move is a human player, the move will likely be made by a user action (button press or mouse click, etc); this will be handled on the FX Application thread anyway.
When the state of the game changes so it is the turn of an "artificial" player to make a move, have the object representing the artificial player calculate its next move, and then update the game state. Since this is a response to the game state changing (it's now the turn of the artificial player), this will also be on the FX Application Thread.
The only (slight) complexity comes if the calculation of the move for the artificial player takes a long time. You don't want to perform this long running calculation on the FX Application Thread. The cleanest way to manage this is to launch a Task which calculates the desired move, and then updates the game state when the move is ready. So, something like this:
GameState game = ... ;
// UI is bound to the game state.
ExecutorService executorService = ... ;
final Player currentPlayer = game.getCurrentPlayer() ;
final Task<Move> calculateMoveTask = new Task<Move>() {
     @Override
     public Move call() {
          Move move = // compute next move...
          return move ;
calculateMoveTask.setOnSucceeded(new EventHandler<WorkerStateEvent>() {
     @Override
     public void handle(WorkerStateEvent event) {
          gameState.makeMove(currentPlayer, calculateMoveTask.getValue());
executorService.submit(calculateMoveTask);
If you're doing more threading than that, you're probably doing it wrong... . There should also be no need for anything to be held as a "global" static variable (the idea above is the only structural modification you need to the example posted by jsmith).

Can I install Windows 8 (DEMO) on a MAC and play windows based games ?

Can I install Windows 8 (DEMO) on a MAC and play windows based games ?

I installed the Developer beta with Bootcamp Assistant yesterday and was very impressed with the ease of the installation. Unfortunately, and I don't know if this is a problem with my video BIOS on my Macbook Air, but Windows 8 installs with two screens split horizontally - so it's effectively useless.
I tried 3 times and gave up. The same thing happens with Linux distributions, however with Linux I can pass "nomodeset" on the kernel command line which fixes it. I don't know how to do that in Windows.
This was happening with both 64x and 32-bit Win8 fwiw.
Oh, also...when I was trying to play around with Bootcamp.exe inside Windows 8, I remember a message popping up saying Bootcamp is only configurable with Windows 7 ISOs. But aside from the kernel graphics issues and some driver compatibility problems, Bootcamp loaded the Win8 ISOs fine.

Attempts in Making a Turn-Based Combat System like Earthbound

For a couple days now, I have been trying to figure out how to manipulate LINGO scripts for a counter, random value generator, and other types to create a turn-based combat system that's similar to Earthbound for a project.
So far, I have the if then codes instantaneously moving the player from one marker to the next, but I can't figure out how to do the following:
1. Damage
2. Health Bar
3. Random Crit Generator
4. Healing
5. Player Controlling more than one sprite
6. Counter-Attack Competent AI scripting
Can anyone help me? I sorta have the health and the player controlling more than one sprite, but any help would be appreciated!

X-Fi and DirectX 9 based gam

Hi!
Well, i'm really happy with the card overall but i have the same issue as priyajeet(he posted it in the crackle/pop thread.
Here's the thing, i can't play any directX based game. I do play OpenGL based games without any issue.
Tried few DX games so far, HL2 based games, BF 242 and Gunmetal, in all the same problem occurs, the screen goes black, system hangs, sounds in loop.
priyajeet was probably ignored cause he has nforce4 based board, that's not my case.
Pentium 4E 2.8GHz
Asus P4P800 SE Bios Version: 0 (latest non-Beta) (northbridge 865PE with Southbridge ICH5)
OCZ 2x52Mb DDR (Dual channel)
2x seagate 200GB SATA II in Hardware raid 0
PSU LC Power 550W
XFX 6600GT 28Mb DDR3
X-Fi Platinum (not in shared IRQ, it has IRQ 22 all for herself)
Some Ethernet PCI card based on a Realtek chipset
LG DVD Player
Philips CD recorder
I don't feel that the peripherals need to be posted with detail(Speakers, mouse, keyboard, printer, monitor)
It kinda seems that this is resources issue, since any openGl based game will work fine and DirectX based games work for few seconds till it crashes.
If anyone has any ideas or sugestions or questions about the current configuration of my computer, both hardware or software please answer, i really like this sound card and i would like to keep it, but i won't if the issues remain.
Best regards,

How embarrassing, I'd be lucky if my cpu was operating at 600Mhz. The computer is an all-in-one IBM handmedown from dad that was purchased in 200. He crashed the harddri've (at least it broke down) & left it to me to upgrade. Now running multiboot C:\98SE Vs D:\winXP on a 20Gb Samsung HDD with intergrated audio/usb.. The machine is a netvista 27952A & it's not clear at all what sort of soundblaster was put onboard b4 sale. I was checking through the bios yesterday & using a diagnostix app. on diskette downloaded from IBM/lenovo website which showed the sound card has no I/0 addresses at all! The system information IDs the sound card OK but says its not configured & F help goes on to say I need soundblaster pro or compatible sound card. OK so I came here, to creative labs, looking for low profile PCI cards and finally figure out it's really not the hardware that I need it's the software (ie: cd-rom or web-link). There is a possibility that new soundcard in the ethernet expansion slot would work v. well but I'd be messing up some particularly neat hardware. What do you think? If I hadn't found your reply here I was going to start a new thread "sound card with no I/0 address". I have put the qr6z07.exe audio file from IBM website in place + reboot & also have used the IBM nati've cd-rom recovery console to reinstall o/s. Have had rare patches of internal speaker system & cd-rom playback but the twin stereo speakers don't make a peep unless you switch the power off, 24 months or so now and v. frustrating:angry:. I'm running out of time to complete the machine b4 support dries up altogether... I was thinking I be able to?network it in combo with a dual core server to surf & be you know 'long board sentimental'.

WEBI prompt based on bex variable suppress not assigned hashtag value in LOV

Hi,
is it possible to suppress the "Not assigned (#)" value from the list of values in a webi prompt based on a bex variable?
This "Not assigned" value is something BW specific, BW adds this to each characteristic automatically?!
WEBI:
RSRT:
It needs to work in WEBI, not only in RSRT, and the filtering of data still needs to work.
For rsrt it works, when you exclude the not assigned value in "Filter > Characteristic Restrictions" and use the bex variable in/through "Filter > Default Values", but this does not work in WEBI, because the BEX Query Data is not filtered on the in the prompt selected value.
Thanks.
Regards
David

Thanks David for a quick reply !
I could manage to avoid # values in WebI prompt using BAdI implementation, here is the brief:
Problem:
WebI report prompt (which shows BEx variable) list of values shows blanks or # . Rrequirement was to avoid these blanks or #
Environment:
BW 7.3
BO 4.0
BW Cube > BEx Query > OLAP Connection > WebI report
Solution:
InfoObject Level1 in BW had # values in masterdata, this could not be deleted since it was in use with other Cubes.
Vaurable Var_Level1 displays # when pressed F4 running BEx query and in list of values in WebI report prompt.
I implemented BAdI on Level1 info object and variable Var_Level1.
Steps to implement BAdI are as in following link
BEx Query - Control the values which are shown on F4
Used following code to elimitate #.
METHOD IF_RSR_VARIABLE_F4_RESTRICT~GET_RESTRICTION_FLAT.
