• How do I hook into a game and write a script to manipulate it?

  - by Ethan

  Hey SO, I know this is a pretty open question but I was wondering how people go about writing scripts that will "play" a game, or manipulate it in some way. I had been thinking that I'd try to get a working AI to play a game for fun, but don't even really know where to start. Are there any good resources to learn this? What are good languages to use? Once I have the language, how do I get my script hooked into the game? I was thinking of just trying simple flash games, if that helps. Thanks a bunch!

• Java Applet - ArrayIndexOutOfBoundsException

  - by Dan

  OK so I am getting an ArrayIndexOutofBoundsException. I don't know why. Here's my code: http://www.so.pastebin.com/y5MjD1k3 The thing is when I go to the red brick at board[2][2]... I go there. Then I go up... then I TRY go to back down but that error pops up. Also when I go to the right 8 squares... I ALSO get that error. ALSO, pretend my 2d map is split into FOUR squares... well square one is the top left... if I go ANYWHERE else ... I get that error. What am I doing wrong? Thanks.

• Customizing Bugzilla 4.0.2 Bug ID numbers

  - by Marcus Polk

  Is it possible to customize Bugzilla bug numbers and add a letter designator, to immediately know it came from Bugzilla? My company is evaluating Bugzilla and has now added many new bugs. We also use 2 other bug databases. This wasn't my decision and I believe they were trying to incorporate better reporting, etc. I read an answer here about "seeding" Bugzilla bug numbers, by setting the "AUTO_INCREMENT" field in the "bugs" table to a different value. I wish I would've thought about this sooner and found this board. Setting that value to start at 9000 or some extraordinary value would have ensured that we knew exactly which bugs came from Bugzilla. However, would it be possible to change the field in the "bugs" table to accept letters, as well? Of course that would probably just mess up the whole auto incrementing of the numbers. Any help or advice is greatly appreciated. Thank you.

• how to implement a game character task queue

  - by Stephen Lee Parker

  I'm working on a personal game engine in C# and need to give certain characters / sprites responses to conditions or certain patterns that they follow and since these patterns will be repeated over and over for other characters / sprites, I don't want to tie the patterns to the character / sprite. I will likely want to define the conditions / actions in level data files... I plan to use this for platformers, space shooters, and pack man like games... Almost an extenable AI system. Any suggestions on how this can be implemented?

• Programming tutorials for people with zero experience

  - by www.aegisub.net

  A friend of mine is interested in learning how to program computers, but she knows nothing about programming. I suggested that Python might be a good language to start with, but after some googling, I couldn't find any tutorials that covered both programming and Python in an adequate way. I don't want her to go through the tiresome "learn algorithms in pseudocode first" routine. Instead, I'd like a tutorial that will explain the basic ideas while working towards a real goal, e.g. a very simple console game. Does anyone know of any such tutorials? Do you think that I'm mistaken in how I'm handling this? Is Python a bad choice? I know that something like C, C++ or Java won't work - too many details will be very counterproductive. On the other hand, I think that Lisp might be too mathematical and abstract. Python, on the other hand, will let her even do something like coding primitive graphical games in a short period of time.

• Facebook Card Game? Which architecture?

  - by Ben

  I am developing a Facebook Card Game for my thesis and i am wondering which architecture fits best? I am going to develop the game using Silverlight + ASP.NET. On the one side the game should contain player vs. player card games. On the other there will be also a lot of contant similar to Mafia Wars(or any other game like that) where you just interact with the server (incl. database) I read a lot about ASP.NET MVC, Silverlight MVVM and that stuff. But what fits best for a game like that? Also i am not sure if i should go with Silverlight 4 already? I don't want to start the wrong way. I really appreciate your help.

• C# How to download files from FTP Server

  - by user3696888

  I'm trying to download a file (all kinds of files, exe dll txt etc.). And when I try to run it an error comes up on: using (FileStream ws = new FileStream(destination, FileMode.Create)) This is the error message: Access to the path 'C:\Riot Games\League of Legends\RADS\solutions \lol_game_client_sln\releases\0.0.1.41\deploy'(which is my destination, where I want to save it) is denied. Here is my code void download(string url, string destination) { FtpWebRequest request = (FtpWebRequest)WebRequest.Create(url); request.Method = WebRequestMethods.Ftp.DownloadFile; request.Credentials = new NetworkCredential("user", "password"); request.UseBinary = true; using (FtpWebResponse response = (FtpWebResponse)request.GetResponse()) { using (Stream rs = response.GetResponseStream()) { using (FileStream ws = new FileStream(destination, FileMode.Create)) { byte[] buffer = new byte[2048]; int bytesRead = rs.Read(buffer, 0, buffer.Length); while (bytesRead > 0) { ws.Write(buffer, 0, bytesRead); bytesRead = rs.Read(buffer, 0, buffer.Length); } } } }

• How can I improve my programming skills with out a computer (or reading material)?

  - by Tom Duckering

  Given the recent and continued chaos with grounded flights and folks stuck in airports, and what not, I'm wondering if anyone has any suggestions for activities that would help sharpen and develop a progammer's mind. The constraints are: Laptop is out of battery and there are no free sockets. You're bored of the book you're reading or you have none with you. Reasonable resources such as a pen and pad of paper are available. Rules can be bent within reason. As daft examples, things I have thought about are: How I might optimise the boarding of a plane. How I might improve the UI of a departure board.

• Categorized SharePoint Discussion - default category to parents category on reply.

  - by Greg Ogle

  I have a Discussion Board in a SharePoint site which has an additional column named Category. When a new discussion is created, it prompts for Category, and of course this is by design. The problem is that when the discussion is replied to, it prompts for the category again. How can I separate the reply functionality so that the Category is not prompted and the Category is set to that of the discussion under which it resides? I attempted to edit a copy of NewForm.aspx in SharePoint Designer, but you can only edit which WebPart it is using, not which fields are displayed.

• Looking for a managed image parser library (JPEG, BMP, PNG, GIF)

  - by usr

  I am writing a discussion board software that will have "avatar" images for the users. I want to resize any picture that gets uploaded to a reasonable size. I could easily do that with System.Drawing but that is relying on GDI+ which has hat security problems before. The problem is that the images are untrusted. So I thought of using a fully managed lib to solve that problem because managed code cannot escape the sandbox (of course it can, but only if the code is user-supplied which it is not in my case). So does anybody know of a managed image parser library for JPEG, BMP, PNG and GIF? If some format is missing than I will have to live with that. Edit: Paint.NET also relies on GDI+. You might be interested in the discussion below, too.

• Even lighter than SQLite

  - by Richard Fabian

  I've been looking for a C++ SQL library implementation that is simple to hook in like SQLite, but faster and smaller. My projects are in games development and there's definitely a cutoff point between needing to pass the ACID test and wanting some extreme performance. I'm willing to move away from SQL string style queries, allowing it to be code driven, but I haven't found anything out there that provides SQL like flexibility while also preferring performance over the ACID test. I don't want to go reinventing the wheel, and the idea of implementing an SQL library on my own is quite daunting, even if it's only going to be simple subset of all the calls you could make. I need the basic commands (SELECT, MODIFY, DELETE, INSERT, with JOIN, and WHERE), not data operations (like sorting, min, max, count) and don't need the database to be atomic, or even enforce consistency (I can use a real SQL service while I'm testing and debugging).

• Level designing with Cocos2d and Box2d

  - by Majster

  I want to learn how to make levels using cocos2d and box2d (for iOS). I am talking about a 2d platformer such as Limbo or Braid or something like that. How can I design and build levels like this? I have seen Level Helper for cocos2d but its not free and I don't think it makes physic objects for box2d. How is this accomplished in real games? How to make camera move with character and so on. Any starting points would be much appreciated.

• Use count or have a field that tallies?

  - by Dan LaManna

  Fairly simple concept, making an extremely basic message board system and I want users to have a post count. Now I was debating on whether or not to have a tally in their row that is added each time a post by them is created, or subtracted by one each time a post of theirs is deleted. However I'm sure that performing a count query when the post count is requested would be more accurate due to unforseen circumstances (say a thread gets deleted and it doesn't lower their tally properly), however this seems like it would be less efficient to run a query EVERY time their post count is loaded, especially in the case of them having 10 posts on the same page and it lists their post count each post. Thoughts/Advice? Thanks

• Take input through Buttons in java

  - by stash211

  I understand that the title might not be descriptive enough, but I'm making a magic square game in Java and basically, I'm trying to replicate user input as found in the sudoku game here: http://www.websudoku.com/. What I have is a n x n grid of Buttons (not JButton) as the board and what I want the user to be able to do is when the user clicks on one of the buttons, similar to the game above, it allows the user to type in his guess in the button itself instead of popping up a dialog box with an input field of some sort. I don't know where to start, I am a beginner in Java (not very beginner, but my knowledge with the various Java APIs is very limited), so I'm trying to find out if this would be possible and if it is, how would I go about doing it? Thanks for any help.

• Vectors for a 2D/3D World in Java

  - by jax

  I reading about Mathematics in Games and am wondering what is the best way to represent a Vector location in Java. I know there is a Vector class but I don't think this is what I need. There is also a Matrix class which looks like it may be what I want (a 1 dimensional matrix maybe). In particular, if I were to create a location Vector such as: v(x,y,z) where x,y and z are the coordinates in 3D space, what would be the best way to represent this in Java. It would be nice if I could also add, subtract and find the dot-product of Vectors. ideas?

• Most proper way to use inherited classes with shared scopes in Mongo?

  - by Trip

  I have the TestVisual class that is inherited by the Game class : class TestVisual < Game include MongoMapper::Document end class Game include MongoMapper::Document belongs_to :maestra key :incorrect, Integer key :correct, Integer key :time_to_complete, Integer key :maestra_id, ObjectId timestamps! end As you can see it belongs to Maestra. So I can do Maestra.first.games But I can not to Maestra.first.test_visuals Since I'm working specifically with TestVisuals, that is ideally what I would like to pull. Is this possible with Mongo. If it isn't or if it isn't necessary, is there any other better way to reach the TestVisual object from Maestra and still have it inherit Game ?

• What are the advantages of combination WPF + XNA?

  - by MartyIX

  Hi, I'm porting my application from Winforms+XNA to WPF (+ XNA?) and I would like to know if the combination WPF + XNA makes sense or not. If it brings some advantages or if it is rather a bad choice. A few points about my game: It's a desk game with simple 2D animations (movement) Main window contains panels like available games/players etc. + console. I would like to add some fancy scenes to my program (at end of game, ...) http://www.codeproject.com/KB/WPF/XnaInWPF.aspx is the code I would like my program base on. So the appearance is quite similar to a chess program. Thank you for suggestions!

• css3 nth child question

  - by JCHASE11

  Hello. I am designing a 960px wide layout with an unordered list. Each list item is 240px wide, so 4 list items fit horizontally in a row. I have about 20 rows on the page.... I want every other list item to have a background of #ececec, so my css would be: ul li:nth-child(2n+2){ background-color:#ececec; } This works. The only problem is because there are 4 items in a row (an even #), the next row would be identical, thus rendering background colors on every 1st and 3rd list items in a row. This is not the effect I am looking to achieve. I want the background colors to alternate, creating a grid-like effect. What is the correct css to do so (think a checker board). Thanks!

• What is the best platform/language for a 3D game in a web browser?

  - by CodeJustin.com

  I have enjoyed making 2D games in various langues (actionscript 3.0, java, python, others) but now I'm ready to move into 3D and to really get me amped up while learning 3D development I'm going to attempt to make a 3D multiplayer game (I already have server written in python). I'm looking for a platform that will run a 3D game well in the browser on low end computers with low end internet. What first came to mind was try Java or use flash/silver light with a 3D framework but I wanted to ask the good people of stackoverflow since performance is a big part of my needs and also good documentation is a plus since I'm just starting 3D development. (the programming language does not matter)

• Resizing uploaded images based on a maximum width in django (PIL)

  - by AndrewE

  I'm working on a simple message board app in Django that lets people upload images to be displayed in their posts. Since the div containing the posts is only 700px, I want to resize the uploaded images to a max width of something like 680px to save space rather than using css to display an image that's too large within the space constraints. I've been searching this site, google and the PIL docs for a while and haven't found any way of resizing an image on one dimension while maintaining the original aspect ratio. Given my inexperience, it's possible that I'm just not recognizing a solution that's plain to someone who knows what to look for.

• Issue with Z-Index and IE7

  - by Chris

  I've browsed on the board and tried and bunch of these solutions and I'm still stuck. The page I'm looking at is here. In IE7, the drop downs are showing up behind the homepage content. And if you go to one of the site sections, by clicking on "Menus", they even show up behind the dynamically created side-bar. I've given the drop down a z-index of 1000 and relative positioning. On the homepage, the images have relative positioning and a small z-index (1 or 2). Any ideas?

• Is it stable to change I/O direction on microcontroller repeatedly?

  - by SS

  I'm new to microcontroller programming and I have interfaced my microcontroller board to another device that provides a status based on the command send to it but, this status is provided on the same I/O pin that is used to provide data. So basically, I have an 8-bit data line that is used as an output from the microcontroller, but for certain commands I get a status back on one of the data lines if I choose to read it. So I would be required to change the direction of this one line to read the status thus converting this line as an ouput to an input and then back to an output. Is this acceptable programming or will this changing of the I/O pin this frequently cause instability? Thanks.

• Delete database. Entity Framework

  - by Idotz

  I have a very annoying issue and I would love a solution. The problem: I followed the MDSN tutorial- http://www.asp.net/mvc/tutorials/mvc-4/getting-started-with-aspnet-mvc4/adding-a-model Then I tried this guide according to my needs and I set up a database GAMES.MDF.   Then, I deleted the database and set it up again, is supposedly work (I can write and read data), but There is no such database in the APP_DATA folder. Like it keeps it somewhere in my PC and reuse it.   I even tried a new project and it did not work, works but not in the library, and it even uses the data I created before. I even deleted the DB from SQL Server Management Studio 2008. Does anyone know what the hell? How do I delete it permanently, not to remain any trace of him?   Thank you.  Ido

• Javascript looping only through defined properties of array. How?

  - by Beck

  For example if i'm keeping array of references via id like that: if(typeof channel_boards[misc.channel_id] == 'undefined') { channel_boards[misc.channel_id] = $('<div class="channel" channel_id="'+misc.channel_id+'"></div>').appendTo('#board'); } And then i'm looping through array to find required reference. I'm looping through undefined properties as well. Is it possible to loop only through defined properties? for(i=0;i<channel_boards.length;i++) { if(channel_boards[i] != undefined) { if(channel_boards[i].attr('channel_id') != visible) {channel_boards[i].addClass('hidden_board');} else {channel_boards[i].removeClass('hidden_board');} } } Maybe i should change the way i'm storing references? Via object for example, but how i'll be able to find proper reference via id number.

• C++ online Role Playing Game (RPG)

  - by David

  So I've been learning C++ and SDL to make some basic 2d games. I want to create a game sort of like World of Warcraft but a 2D version. I want it to be on-line and use a database or something to start data like amount of Gold, HP, etc. I was wondering though, if I do this in SDL, would it still work on-line or would the user have to download SDL themselves to play? I just want a game like this but be able to play it with some friends, just for learning purposes you know. I was also looking at DirectX because everyone has that on windows pretty much. Anyways much help is appreciated, thanks!
