• Microeconomical simulation: coordination/planning between self-interested trading agents

  - by Milton Manfried

  In a typical perfect-information strategy game like Chess, an agent can calculate its best move by searching the state tree for the best possible move, while assuming that the opponent will also make the best possible move (i.e. Mini-max). I would like to use this approach in a "game" modeling economic activity, where the possible "moves" would be to buy or sell for a given price, and the goal, rather than a specific class of states (e.g. Checkmate), would be to maximize some function F of the agent's state (e.g. F(money, widget) = 10*money + widget). How to handle buy/sell actions that require coordination between both parties, at the very least agreement upon a price? The cheap way out would be to set the price beforehand, maybe based upon the current supply -- but the idea of this simulation is to examine how prices emerge when freely determined by "perfectly rational" agents. A great example of what I do not want is the trading algorithm in SugarScape -- paraphrasing from Growing Artificial Societies p101-102: when a pair of agents interact to trade, they each compute their internal valuations of the goods, then a bargaining process is conducted and a price is agreed to. If this price makes both agents better off, they complete the transaction The protocol itself is beautiful, but what it cannot capture (as far as I can tell) is the ability for an agent to pay more than it might otherwise for a good, because it knows that it can sell it for even more at a later date -- what appears to be called "strategic thinking" in this pape at Google Books Multi-Agent-Based Simulation III: 4th International Workshop, MABS 2003... to get realistic behavior like that, it seems one would either (1) have to build an outrageously-complex internal valuation system which could at best only cover situations that were planned for at compile-time, or otherwise (2) have some mechanism to search the state tree... which would require some way of planning future trades. Note: The chess analogy only works as far as the state-space search goes; the simulation isn't intended to be "zero sum", so a literal mini-max search wouldn't be appropriate -- and ideally, it should work with more than two agents.

• Is it a good idea to use a formula to balance a game's complexity, in order to keep players in constant flow?

  - by user1107412

  I read a lot about Flow theory and its applications to video games, and I got an idea sticking in my mind. If a number of weight values are applied to different parameters of a certain game level (i.e. the size of the level, the number of enemies, their overal strength, the variance in their behavior, etc), then it should be technically possible to find an overal score mechanism for each level in the game. If a constant ratio of complexity increase were empirically defined, for instance 1,3333, or say, the Golden Ratio, would it be a good idea to arrange the levels in such an order that the increase of overal complexity tends to increase that much? Has somebody tried it?

• Collaboration platforms

  - by Thomas

  Are there any good collaboration platforms for game development? This would include the following features: Easy way to find various people you need to build games (programmer, artist etc) and forming a team like for example codeplex Online portfolio for users where they can offer their services (either paid or free) Posibility to create a game specific blog or site with social media integration to show the world what's being created Easy way to manage game content / resources with sufficient online storage, version control and if possible source control Manage all phases of game development (startup, creating concept, finding a team, creating proof of concept, production phase etc) and publish specific information for each phase also on social media etc. Manage asset creation flow (request for specific content like a sound, production of sound, uploading the sound, notification to the requester, implementation of the file, retouching in several cycles etc)

• Child object free movement on Parent object

  - by The415

  Just to be straightforward, I am completely new to many aspects of coding and am searching for different specs and guidelines to aid me on my journey to crafting a wonderful game in Epic Games' Unreal Engine 4. Okay, I know upon viewing this, some may have little to no clue what I mean, so I'll put it like this to explain what I mean : Imagine a third person game with a simple model of a character. Now, say I have an object as a torso of a character in a game. Now Say I have an object as a head of the character. How could I keep the head as a child of the torso, but at the same time, allow it to move with the camera angle.

• Fixing Mobility Radeon HD3650 driver in 12.04 LTS

  - by Kevin

  Okay, I know the subject has been discussed many times, but i dont find any of the instructions working. Most promising guide was here https://launchpad.net/~makson96/+archive/fglrx ive also tried https://help.ubuntu.com/community/BinaryDriverHowto/ATI because since the driver installation was written on other sites as well, this page included a "patch" file, but since im unaware how to patch installations, im out of luck. If i understand correctly, the patch should fix the driver and eliminate constant error messages. My system is 64bit 12.04 LTS and card is Mobility Radeon HD3650. Usual installation of the driver results in weird display resoulution (1100x something, while it should be 1440x900) and even 3d games did not work. Can anyone give me any more pointers? Much appreciated!

• Hiding a HTTP Auth-Realm by sending 404 to non-known IPs?

  - by zhenech

  I have an Apache (2.2) serving a web-app on example.com. That web-app has a debug-page reachable via example.com/debug. /debug is currently protected with a HTTP basic auth. As there is only a very small user-base who has access to the debug-page, I would like to hide it based on IP address and return 404 to clients not accessing from our VPN. Serving a 404 based on IP-address only is easy and is described in http://serverfault.com/a/13071. But as soon I add authentication, the users see a 401 instead of a 404. Basically, what I need is: if ($REMOTE_ADDR ~ 10.11.12.*): do_basic_auth (aka return 401) else: return 404

• What makes Instagram so valuable? [closed]

  - by ????

  If as in the FAQ, that topics about business (computer industry) is allowed here, I'd like to find out why Instagram can be so valuable, that it is acquired for $1 billion dollars (USD). To put it simply, isn't it just a photo enhancement app (such as making a photo vintage look), plus sharing those photos on Facebook? That's because in contrast, PlayFish had superb Facebook games, and many of them, and are so much more sophisticated (such as Restaurant City and Pet Society). And PlayFish was merely acquired for $400 million. Some companies such as RockYou, had the number one app on Facebook, but wasn't even acquired for a low price like $200 million. And now just a photo filter app and sharing photos, and it is a business considered to be worth a billion dollars. Why is that?

• Linux,Apache,NetBeans,PHP == Windows,IIS/Cassini,Visual Studio,ASP.Net

  - by Neil Smith

  I've worked out how to get my linux based Netbeans PHP development machine to behave much like what happens when you create a new ASP.Net project in Visual Studio. Firstly create multiple PHP project in Netbeans,say for example mysite1 and mysite2. Next edit the apache2/sites-enabled/000-default file and add two virtualhost sections as below <VirtualHost 127.0.1.1> ServerName mysite1.localhost DocumentRoot /var/www/mysite1/ </VirtualHost> <VirtualHost 127.0.2.1> ServerName mysite2.localhost DocumentRoot /var/www/mysite2/ </VirtualHost> For each site you add, pick a different ip address similar to the above where I use the third octet to increment, next edit the etc/hosts file and add the following two lines 127.0.1.1 mysite1.localhost 127.0.2.1 mysite2.localhost Then in Netbeans, go to File->Project Properties click on 'Run Configuration' and set 'Project Url' to http://mysite1.localhost for the first project and http://mysite2.localhost for the second project. That will give you a PHP development box which develops multiple PHP projects similar to how a Visual Studio Windows based box handles multiple ASP.Net sites. Hope this helps someone :)

• Reliable 1tb or larger hard drive?

  - by jasondavis

  I am in the market for 2-3 new drives, I would like each to be at least 1tb to 2tb in size. I have been reading all the reviews on newegg.com for 1tb and larger drives and they all have 1 thing in common. Almost all the ones I read about have complaints of them being DOA or dieing within a few weeks of use. I am hoping to find some drives with this storage range that have a reputation for lasting a long time instead of a short life. Please help me if you have any experience with these sort of drives? Most the ones I read about were Western Digital brand. I realize some might complain that this questions answer would be based upon a timeframe, so if a user searches and find this answer a year from now it will be outdated but I would appreciate any help based on the current hard drives available as of April 10th, 2010 on newegg.com

• Is it wise for a programmer to move into management?

  - by Desolate Planet

  Many times, a developer has suggested that I become a team leader because I'm motivated, but during my career in the IT industry, I've seen so many people who are great at programming, move into management and they are miserable. I've also seen many managers return to programming stating "I'm a technical person, I like technical problems". If this is such a common thing, why do developers feel compelled to leave the technical domain and move into management? Sure you'll have more money and more control, but if you don't enjoy your work and take your problems out on your tream. Secondly, I've been asked in developer interviews, "Would you consider leading a team?" and I'm always tempted to cite the Peter Principle based on what I've seen. I am interested in furthering myself, but not in the way the company may want i.e "Vice President of department blah". To be honest, I've seen this more often in the corporate world than in small development houses and it's always put me off ever going back to a corporate environment. I just feel that this is becoming more and more the norm and it's impacting team morale and degrading the quality of the work. Question: Based on what I've said, Is it a smart move for a technical person to move into management?

• Site Review: Yahoo.com - Forms Evaluation

  Yahoo uses Ajax to suggest search terms to users when they are entering a search phrase into the search text box. Once the user has entered a search term and then presses the search button, the browser will post the search form to the search results page. I think that Yahoo is making great use of Ajax in this situation because they are helping users find information as well as suggesting alternative search terms for them to try based on what has already been added.

• How a graphic designer can get into game programming?

  - by Robert Valdez

  I'm a graphic design student hoping to pursue a career as a video game artist. However, I want to do some game development as a hobby. I'd like to develop games for the desktop or mobile phones. The only programming experience I have is that I took an intro to programming with java class in which I learned how to make web applets using java's swing library. It was awful. I think the only things I took from the class was what OOP is and how to work with variables and data types and some methods. I also learned some actionscript myself which was fun unfortunately my flash tutorial expired and it's too expensive to buy;( What I was looking to do is learn one programming language and build a game with it without having to go through so many hoops and with minimum cost. If it's possible. I would love to learn C++, but I read it's not best for a beginning programmer. What programming languages or maybe software kits/platforms would you recommend?

• open source knowledge base CMS system

  - by Thomi

  I'm looking for an open source knowledge base system that uses tags, rather than free-text search to identify articles (a lot like serverfault does). I've looked at twiki, which many people suggested, but haven't found what I'm looking for. Basically I want to be able to create and tag articles, and provide an easy way for anonymous users to search based on tags. Edit: OK, here's some more detail regarding what I want. Basically, all the knowledge base systems I have seen so far are a collection of articles, each article with a title. Most of them allow you to categorise articles into groups and sub-groups. Users of the system can search for information using a title search, for example "How do I print from AwesomeProduct?" - which then shows a list of any articles that match that search text. This is fine and dandy when your KB is for one version of the software product (the mythical AwesomeProduct ver 1.0). However, the development team then go ahead and create a new version (ver 2.0) that adds many new features and changes some existing features. Now, how do we support both products in the same KB? The Naive method is to copy all articles from 1.0, and update them for 2.0, adding and removing articles in 2.0 as required. We can then add text at the top of every 1.0 article that says: "this articles applies to 1.0 only, to see the 2.0 version, click here" (or something similar) The problem with articles being indexed in the system by title is that it's very hard to filter based on meta-data like version. What happens when we create version 3.0 or 4.0? The end-situation here is that you have a mess of articles. They're hard to search, hard to filter, and even harder to manage. The solution (it seems to me) is to use tags, rather than text as the article index mechanism. So articles can be tagged with a tag representing the software version, topic area etc. etc. Users can then filter based on tag - an example search might be "version_1 printing" - which straight away gives a list of articles with all these tags. So that's what I'm looking for - a KB system that uses tags, rather than text to index many articles. I'm sure I could build something with drupal, but I was hoping for something that worked out-of-the-box.

• Creating my own kill cam

  - by DalexL

  I plan on creating my own kill cam system for a sandbox tool set. After thinking about the mechanics of the kill cam itself, however, I'm quite lost. I'm trying to recreate the ones commonly seen in call of duty games that show, from the view of the killer, the actual killing scene. My Thoughts: -I can't just keep in memory when people kill others because I wouldn't know when to start the 'recording process'. There is on way for me to accurately determine when somebody is 'about' to kill someone. -My only real idea so far is to have a complete duplicate of everything loaded off to the side copying all the movement from the original world but with a 10 second delay. That way, all the kill cams would be 10 seconds long and the persons camera would just be moved to the second world of their killer. My Questions: Is there already an accepted way to do this? Does anybody have any good ideas for something like this? Thanks if you can!

• How does a collision engine work?

  - by JXPheonix

  Original question: Click me How exactly does a collision engine work? This is an extremely broad question. What code keeps things bouncing against each other, what code makes the player walk into a wall instead of walk through the wall? How does the code constantly refresh the players position and objects position to keep gravity and collision working as it should? If you don't know what a collision engine is, basically it's generally used in platform games to make the player acutally hit walls and the like. There's the 2D type and the 3D type, but they all accomplish the same thing: collision. So, what keeps a collision engine ticking?

• How to work with scenes in a 2D game

  - by Anearion

  I'm a java/android programmer, but I don't have any experience in game programming, I'm already reading proper books, like "Pro Android Games", but my concerns are more about the ideas behind game programming than the techniques themselves. I'm working on a 2D game, something like Cluedo to let you understand the genre. I would like to know how should I act with the "scenes", for example, a room with a desk, TV, windows and a lamp. I need to make some items tappable and others not. Is it common to use one image (invisible to the user) with every different item a different color, then call the getColor() method on the image? Or use one image as background, and separate images for all the items? If the latter, how can I set the positioning? and should I use imageView or imageButton? I'm sorry if those are really low quality questions, but as "outsider" ( I'm 23 and still finishing my university ) it's pretty hard learn alone.

• One-way platforms in UDK

  - by Jordaan Mylonas

  I'm looking to make a multi-player platforming game using UDK. I'm currently doing feasibility research, to make sure I will reasonably be able to do all of the technical things I want to do. The first major hurdle I've come across without being able to find as answer, are one-way platforms. That is to say, platforms through which a player can jump up, but not fall through (unless they choose to). These are commonly seen in games like Mario, Kirby and Smash Bros. Does anyone know how such a system would work within UDK? I can think of solutions that might work for single-player, but not multi.
