• What's a way to implement a flexible buff/debuff system?

  - by gkimsey

  Overview: Lots of games which RPG-like statistics allow for character "buffs", ranging from simple "Deal 25% extra damage" to more complicated things like "Deal 15 damage back to attackers when hit." The specifics of each type of buff aren't really relevant. I'm looking for a (presumably object-oriented) way to handle arbitrary buffs. Details: In my particular case, I have multiple characters in a turn-based battle environment, so I envisioned buffs being tied to events like "OnTurnStart", "OnReceiveDamage", etc. Perhaps each buff is a subclass of a main Buff abstract class, where only the relevant events are overloaded. Then each character could have a vector of buffs currently applied. Does this solution make sense? I can certainly see dozens of event types being necessary, it feels like making a new subclass for each buff is overkill, and it doesn't seem to allow for any buff "interactions". That is, if I wanted to implement a cap on damage boosts so that even if you had 10 different buffs which all give 25% extra damage, you only do 100% extra instead of 250% extra. And there's more complicated situations that ideally I could control. I'm sure everyone can come up with examples of how more sophisticated buffs can potentially interact with each other in a way that as a game developer I may not want. As a relatively inexperienced C++ programmer (I generally have used C in embedded systems), I feel like my solution is simplistic and probably doesn't take full advantage of the object-oriented language. Thoughts? Has anyone here designed a fairly robust buff system before?

• Secure Coding Practices in .NET

  - by SoftwareSecurity

  Thanks to everyone who helped pack the room at the Fox Valley Day of .NET.   This presentation was designed to help developers understand why secure coding is important, what areas to focus on and additional resources.  You can find the slides here. Remember to understand what you are really trying to protect within your application.  This needs to be a conversation between the application owner, developer and architect.  Understand what data (or Asset) needs to be protected.  This could be passwords, credit cards, Social Security Numbers.   This also may be business specific information like business confidential data etc.  Performing a Risk and Privacy Assessment & Threat Model on your applications even in a small way can help you organize this process. These are the areas to pay attention to when coding: Authentication & Authorization Logging & Auditing Event Handling Session and State Management Encryption Links requested Slides Books The Security Development Lifecycle: SDL: A Process for Developing Demonstrably More Secure Software Threat Modeling Writing Secure Code The Web Application Hackers Handbook  Secure Programming with Static Analysis   Other Resources: OWASP OWASP Top 10 OWASP WebScarab OWASP WebGoat Internet Storm Center Web Application Security Consortium Events: OWASP AppSec 2011 in Minneapolis

• Entity system in Lua, communication with C++ and level editor. Need advice.

  - by Notbad

  Hi!, I know this is a really difficult subject. I have been reading a lot this days about Entity systems, etc... And now I'm ready to ask some questions (if you don't mind answering them) because I'm really messed. First of all, I have a 2D basic editor written in Qt, and I'm in the process of adding entitiy edition. I want the editor to be able to receive RTTI information from entities to change properties, create some logic being able to link published events to published actions (Ex:A level activate event throws a door open action), etc... Because all of this I guess my entity system should be written in scripting, in my case Lua. In the other hand I want to use a component based design for my entities, and here starts my questions: 1) Should I define my componentes en C++? If I do this en C++ won't I loose all the RTTI information I want for my editor?. In the other hand, I use box2d for physics, if I define all my components in script won't it be a lot of work to expose third party libs to lua? 2) Where should I place the messa system for my game engine? Lua? C++?. I'm tempted to just have C++ object to behave as servers, offering services to lua business logic. Things like physics system, rendering system, input system, World class, etc... And for all the other things, lua. Creation/Composition of entities based on components, game logic, etc... Could anyone give any insight on how to accomplish this? And what aproach is better?. Thanks in advance, HexDump.

• How should I structure my turn based engine to allow flexibility for players/AI and observation?

  - by Reefpirate

  I've just started making a Turn Based Strategy engine in GameMaker's GML language... And I was cruising along nicely until it came time to handle the turn cycle, and determining who is controlling what player, and also how to handle the camera and what is displayed on screen. Here's an outline of the main switch happening in my main game loop at the moment: switch (GameState) { case BEGIN_TURN: // Start of turn operations/routines break; case MID_TURN: switch (PControlledBy[Turn]) { case HUMAN: switch (MidTurnState) { case MT_SELECT: // No units selected, 'idle' UI state break; case MT_MOVE: // Unit selected and attempting to move break; case MT_ATTACK: break; } break; case COMPUTER: // AI ROUTINES GO HERE break; case OBSERVER: // OBSERVER ROUTINES GO HERE break; } break; case END_TURN: // End of turn routines/operations, and move Turn to next player break; } Now, I can see a couple of problems with this set-up already... But I don't have any idea how to go about making it 'right'. Turn is a global variable that stores which player's turn it is, and the BEGIN_TURN and END_TURN states make perfect sense to me... But the MID_TURN state is baffling me because of the things I want to happen here: If there are players controlled by humans, I want the AI to do it's thing on its turn here, but I want to be able to have the camera follow the AI as it makes moves in the human player's vision. If there are no human controlled player's, I'd like to be able to watch two or more AI's battle it out on the map with god-like 'observer' vision. So basically I'm wondering if there are any resources for how to structure a Turn Based Strategy engine? I've found lots of writing about pathfinding and AI, and those are all great... But when it comes to handling the turn structure and the game states I am having trouble finding any resources at all. How should the states be divided to allow flexibility between the players and the controllers (HUMAN, COMPUTER, OBSERVER)? Also, maybe if I'm on the right track I just need some reassurance before I lay down another few hundred lines of code...

• Best design for a "Command Executer" class

  - by Justin984

  Sorry for the vague title, I couldn't think of a way to condense the question. I am building an application that will run as a background service and intermittently collect data about the system its running on. A second Android controller application will query the system over tcp/ip for statistics about the system. Currently, the background service has a tcp listener class that reads/writes bytes from a socket. When data is received, it raises an event to notify the service. The service takes the bytes, feeds them into a command parser to figure out what is being requested, and then passes the parsed command to a command executer class. When the service receives a "query statistics" command, it should return statistics over the tcp/ip connection. Currently, all of these classes are fully decoupled from each other. But in order for the command executer to return statistics, it will obviously need access to the socket somehow. For reasons I can't completely articulate, it feels wrong for the command executer to have a direct reference to the socket. I'm looking for strategies and/or design patterns I can use to return data over the socket while keeping the classes decoupled, if this is possible. Hopefully this makes sense, please let me know if I can include any info that would make the question easier to understand.

• Seamlessly Authenticate with a Secondary Active Directory Server (when primary is down)

  - by LonnieBest

  How do you get workstations to (seamlessly) authenticate with a secondary Active Directory server when the primary one is down? Background: I added a secondary Active Directory server to a company's network, hoping that it would do authentication in the event that the primary Active Directory server was down. Although, the Secondary Active Directory server seems to be replicating correctly, authentication doesn't occur while rebooting the primary Active Directory server. Do I have a misunderstanding regarding the role of a secondary Active Directory server, or are there additional settings I must set to get the workstations to authenticate with it when the primary is down?

• Query something and return the reason if nothing has been found

  - by Daniel Hilgarth

  Assume I have a Query - as in CQS that is supposed to return a single value. Let's assume that the case that no value is found is not exceptional, so no exception will be thrown in this case. Instead, null is returned. However, if no value has been found, I need to act according to the reason why no value has been found. Assuming that the Query knows the reason, how would I communicate it to the caller of the Query? A simple solution would be not return the value directly but a container object that contains the value and the reason: public class QueryResult { public TValue Value { get; private set; } public TReason ReasonForNoValue { get; private set; } } But that feels clumsy, because if a value is found, ReasonForNoValue makes no sense and if no value has been found, Value makes no sense. What other options do I have to communicate the reason? What do you think of one event per reason? For reference: This is going to be implemented in C#.

• Small script to look for Project Replication actions that have failed

  - by Trond Strømme

  Today when looking at a couple of projects on a ZFS 7320 Storage Appliance I noticed on one project that one of its replication actions had failed, as I hadn't checked the Recent Alerts log yet I was not aware of this. I decided to write a small script to check if there were others that had failed. Nothing fancy, just a loop through all projects, look at the project's replication child and compare the values of the last_sync and last_try properties and print the result if they're not equal. (There are probably more sensible ways of doing this, but at least it involves me getting the chance to put on my headphones and doing just a little bit of coding.) script // this script will locate failed project level replication // it will look at the sync times for 'last_sync' and 'last_try' // and compare these, if they deviate you should investigate. // NOTE! this code is offered 'as is' Run at your own risk, // it will probably work as intended, but in now way can I // (or Oracle) be held responsible if your server starts behaving // like a three year old kid in a candy store.. (not that mine do, // they are very well behaved boys...) run('configuration'); run('storage'); printf('Host: %s, pool: %s\n', get('owner'),get('pool')); run('cd /'); run('shares'); proj=list(); printf("total projects: %d\n",proj.length +'\n'); // just for project level replication for(i=0;i<proj.length;i++){ run('select '+proj[i]); run('replication'); //get all replication actions preps = list(); for(j=0;j<preps.length;j++){ run('select ' + preps[j]); last_sync = get('last_sync'); last_try = get('last_try'); // printf("target %s\n", get('target')); //why the flip does this not get the proper name? if(!( last_sync.valueOf() === last_try.valueOf())){ printf("sync has failed for %s %s\n", proj[i], get('target')); }else{ // printf("OK %s %s\n", proj[i], get('target')); } run('done'); //done with the replica action } run('done'); run('done'); } printf("finished\n"); For a more on how to run the script, or testing it please look at my previous post. Sample output: Host: elb1sn01, pool: exalogic total projects: 45 sync has failed for ACSExalogicSystem cb3a24fe-ad60-c90f-d15d-adaafd595639 finished

  Problem: Gmail (and only Gmail) quits working for a period of 5-10 mins only on one computer. Problem occurs several times daily Does not appear to be any "triggering event" - user is simply using Gmail normally when the problem arises User can access their Gmail from other computers on same LAN User can access all other sites, including other Google sites, from affected computer After several mins of outage, Gmail will spontaneously resume normal operation on affected computer The problem occurs in all browsers (Chrome, FF, Safari) Computer: MacBook Pro, OSX 10.7.3, latest browsers I find this very baffling. Any advice welcome.

• Extra Life 2012

  - by Chris Gardner

  Greetings, It's that time of year again. The time when I beg you for money for charity. See, unlike those bell ringers outside Wal-Mart, I don't do it when you have ten bazillion holiday obligations... Once again, I will be enduring a 24-hour marathon of gaming to raise money for Children Hospital in Birmingham. All the money goes straight to them, and you get to tell Uncie Samual that you're good for that money. I'd REALLY like to break $1000 this year, as I have come REALLY close for the past 2 year to doing so. Don't live near me? Live closer to a children's hospital in the Children's Miracle Network? It's OK. Go find a participant that is working for your hospital and hook them up. Just left me know, I will will join in with the karmic love you will already receive. This year, the event will take place on October 20th, beginning at 8 A.M. Once again, I will try to provide some web streams, etc, if you want to point and laugh (especially if I have to result to playing Dance Central at 4 AM to stay awake for the last part.) Look at it this way, I'm going to badger you about this for the next month. You might as well donate some money so you can righteously tell me to shut the Smurf up. You can place your bid at the link below. Feel free to spread the word to anyone and everyone. I thank you. The children thank you. Several breeds of feral platypus thank you. Maybe, just maybe, doing so will will help you feel the love felt by re-fried beans when lovingly hugged in a warm tortilla. Enjoy your burrito. http://www.extra-life.org/participant/cgardner

• State changes in entities or components

  - by GriffinHeart

  I'm having some trouble figuring how to deal with state management in my entities. I don't have trouble with Game state management, like pause and menus, since these are not handled as an entity component system; just with state in entities/components. Drawing from Orcs Must Die as an example, I have my MainCharacter and Trap entities which only have their components like PositionComponent, RenderComponent, PhysicsComponent. On each update the Entity will call update on its components. I also have a generic EventManager with listeners for different event types. Now I need to be able to place the traps: first select the trap and trap position then place the trap. When placing a trap it should appear in front of the MainCharacter, rendered in a different way and following it around. When placed it should just respond to collisions and be rendered in the normal way. How is this usually handled in component based systems? (This example is specific but can help figure out the general way to deal with entities states.)

• Help me find the offending process waking my Windows 7 PC from hibernate every night

  - by DavidGugick

  Recently my Windows 7 64-bit PC has started waking every night from hibernation around 3:30am. I have done the following to try and figure out what is causing the issue with no luck: Examined the Windows Event logs. Nothing is noted Ran powercfg -lastwake and that reports nothing c:\powercfg -lastwake Wake History Count - 1 Wake History [0] Wake Source Count - 0 Ran powercfg to find what devices are armed for wake. Interestingly, this reports two items (I've already unchecked the "Allow this device to wake the computer" in device manager): The keyboard and something called the "eHome Infrared Receiver (USBCIR)". This is a desktop PC and it does not have an Infrared received, so I'm not sure what that device is. Suffice to say it does not have the option to "Allow device to wake..." available in Device Manager. C:\powercfg -devicequery wake_armed eHome Infrared Receiver (USBCIR) HID Keyboard Device My next step is to disable the Keyboard from wake, but I'm not convined that's the problem. This is on a Dell XPS435 if that helps anyone.

• Simple thruster like behaviour when rotating sprite

  - by ensamgud

  I'm prototyping some 2D game concepts with XNA and have added some basic keyboard inputs to control a triangle sprite. When I press key up the sprite accelerates in it's current facing direction, when I release the key it brakes down. For rotation, when I press left/right keys I rotate the sprite. Currently the sprite immedately changes direction when I rotate it. What I want is for it to keep moving in the same direction when I rotate, until I hit key up, adding thrust in whatever direction the sprite is pointing at. This would simulate thrusters on a classic space shooter like Asteroids. I'm adding an image to describe the behaviour I'm after and some code samples of how I'm doing things at the moment. This is my player struct, holding information of the sprite. public struct PlayerData { public Vector2 Position; // where to draw the sprite public Vector2 Direction; // travel direction of sprite public float Angle; // rotation of sprite public float Velocity; public float Acceleration; public float Decelleration; public float RotationAcceleration; public float RotationDecceleration; public float TopSpeed; public float Scale; } This is how I'm currently handling thrusting / braking (when pressing/releasing key up) (simplified, removed some bounds checking etc): player.Velocity += player.Acceleration * 0.1f; player.Velocity -= player.Acceleration * 0.1f; And when I rotate the sprite left and right: player.Angle -= player.RotationAcceleration * 0.1f; player.Angle += player.RotationAcceleration * 0.1f; This runs in the update loop, keeps the direction updated and updates the position: Vector2 up = new Vector2(0f, -1f); Matrix rotMatrix = Matrix.CreateRotationZ(player.Angle); player.Direction = Vector2.Transform(up, rotMatrix); player.Direction *= player.Velocity; player.Position += player.Direction; I am following along various beginner tutorials and haven't found any describing this, but I have tried some on my own without success. Do I need to change my velocity and acceleration fields to Vectors instead of floats to accomplish this type of movement? I realise my Angle and the Direction vector is currently tied together and I need to disconnect these somehow to be able to rotate freely without changing the direction of the movement, but I can't quite figure out how to do this while keeping the acceleration/decceleration functional. Would appreciate an explanation rather than pure code samples. Thanks,

• Windows7 - Mouse not working, all windows + tray act like inactive

  - by Teo.sk

  I have this problem for two days now. First when it happened, logging out and back in helped, but now this occurs right after booting. I cannot activate any window by clicking into it, and also cannot minimalise, or close it with mouse. In few applications I cannot even interact with them with mouse (e.g. clicking on links in browser). I can scroll an active window with the trackball, and sometimes everything works normally for a little while. Everything works fine, when I use keyboard for this, I can resize, move, close windows with keyboard shortcuts, etc. I ran a complete Avast! scan, but it found nothing important. Also event viewer did not show any relevant errors. Here's a log from HijackThis if it helps anything.

• Is it considered poor programming to do this with xna components?

  - by Rob

  I created my own Menu System that is event driven. In order to have a loading screen and multithreaded loading to work, I devised this sort of implementation: //Let's check if the game is done loading. if (_game != null) { _gameLoaded = _game.DoneLoading; } //This means the game is loading still, //therefore the loading screen should be active. if (!_gameLoaded && _gameActive) { _gameScreenList[2].UpdateMenu(); } //The loading screen was selected. if (_gameScreenList[2].CurrentState == GameScreen.State.Shown && !_gameActive) { Components.Add(_game = new ParadoxGame(this)); _game.Initialize(); //Initializes the Game so that the loading can begin. _gameActive = true; } In the XNA Game Component that contains the actual game, in the LoadContent method I simply created a new Thread that calls another method ThreadLoad that has all the actual loading. I also have a boolean variable called DoneLoading in the XNA Game Component that is set to true at the end of the ThreadLoad. I am wondering if this is a poor implementation.

• "Oracle Coherence 3.5" Book - My Humble Review

  - by [email protected]

    After reviewing the book in more detail I say again that it is a great guide for sure. Lots of important concepts that sometimes can be somewhat confusing are deeply reviewed, including all types of caching schemes and backing maps, and the cache topologies with their corresponding performances and very useful "When to use it?" sections. Some functionalities that are very desirable or used a lot are reviewed with examples and best practices of implementation, including: Data affinity Querying Pagination Indexes Aggregations Event processing, listening and triggering Data persistence Security Regarding the networking and architecture topics, Coherence*Extend is exhaustively reviewed, including C++ and .NET clients, with very good tips and examples, even including source codes. Personally, I am also glad to see that the address providers (<address-provider> tag), new feature in Coherence 3.5 which is a way to programmatically provide well-known addresses in order to connect to the cluster, is mentioned on the book, because it provides new functionalities to satisfy some special configuration requirements for example: Provide a way to switch extend nodes in cases of failure Implement custom load balancing algorithms and/or dynamic discovery of TCP/IP connection acceptors Dynamically assign TCP address and port settings when binding to a server socket Another very interesting and useful section is the "Coherent Bank Sample Application", which is a great tutorial, useful to understand how Coherence interacts with third party products establishing a clear integration with them, including the use of non-Oracle products like MS Visual Studio.

• KB2667402 update fails to install with 0x80004005. Yet it's also showing as installed

  - by growse

  I've got 15 Windows 2008 R2 x64 servers that I manage with SCCM2012. I've noticed during my Windows updates reporting that there's two boxes that are showing as 'error' for total updates installed. Digging around, it looks like the update that is failing to install is KB2667402. The Software Centre on the server itself shows the following: The software change returned error code 0x80004005(-2147467259). So SCCM thinks it hasn't installed the update. However, if I go to the Programs and Features application and select 'Windows Updates', I can see an entry for KB2667402: If I try and uninstall this, I get an error: An error occurred. Not all of the updates were successfully uninstalled If I try and download the patch from Microsoft directly, I get the same error installing as displayed in Software Centre. The only odd thing about this setup that I can think would affect this is that I run the RDP service on a non-standard port. However, I do this across all the servers, so it seems odd that it would fail on just 2 out of 15. The tail of the WindowsUpdate.log file is below: 2012-06-26 15:33:53:184 3924 1608 COMAPI ------------- 2012-06-26 15:33:53:190 3924 1608 COMAPI -- START -- COMAPI: Install [ClientId = CcmExec] 2012-06-26 15:33:53:190 3924 1608 COMAPI --------- 2012-06-26 15:33:53:190 3924 1608 COMAPI - Allow source prompts: No;

• 'server was unable to allocate from the system nonpaged pool' error

  - by cop1152

  Currently users at my company are unable to access their home folder (or any folder on our domain controller). I am working remotely and cant physically access the machine until tomorrow morning, but I can access it with RDC. When I attempt to ping other machines on our network from the machine in question (connected with RDC), I immediately get the error PING: transmit failed. error code 1450. Event Viewer is full of 2019 errors: The server was unable to allocate from the system nonpaged pool because the pool was empty Does anyone have experience with this specific issue? I have found some info with Google, but would like to hear what the pros at SF have top say. This is a Windows 2000 server.

• When is it better to offload work to the RDBMS rather than to do it in code?

  - by GeminiDomino

  Okay, I'll cop to it: I'm a better coder than I am at databases, and I'm wondering where thoughts on "best practices" lie on the subject of doing "simple" calculations in the SQL query vs. in the code, such as this MySQL example (I didn't write it, I just have to maintain it!) -- This returns the username, and the users age as of the last event. SELECT u.username as user, IF ((DAY(max(e.date)) - DAY(u.DOB)) &lt; 0 , TRUNCATE(((((YEAR(max(e.date))*12)+MONTH(max(e.date))) -((YEAR(u.DOB)*12)+MONTH(u.DOB)))-1)/12, 0), TRUNCATE((((YEAR(max(e.date))*12)+MONTH(max(e.date))) - ((YEAR(u.DOB)*12)+MONTH(u.DOB)))/12, 0)) AS age FROM users as u JOIN events as e ON u.id = e.uid ... Compared to doing the "heavy" lifting in code: Query: SELECT u.username, u.DOB as dob, e.event_date as edate FROM users as u JOIN events as e ON u.id = e.uid code: function ageAsOfDate($birth, $aod) { //expects dates in mysql Y-m-d format... list($by,$bm,$bd) = explode('-',$birth); list($ay,$am,$ad) = explode('-',$aod); //Insert Calculations here ... return $Dy; //Difference in years } echo "Hey! ". $row['user'] ." was ". ageAsOfDate($row['dob'], $row['edate']) . " when we last saw him."; I'm pretty sure in a simple case like this it wouldn't make much difference (other than the creeping feeling of horror when I have to make changes to queries like the first one), but I think it makes it clearer what I'm looking for. Thanks!

• Network email alerts

  - by stephenfalken

  I would like to buy or d/l an application that will alert our sysadmin in the event of network failure, like via email and/or phone call. I've looked around the net before posting this question, but I have one main concern: if our network goes down, how can a network monitoring application send email to alert us that it's down? Doesn't this have to be an external application that looks at our network from outside? Well anyway, I want to find something that will handle this for us - freeware if possible, sice we're not looking for heavy analysis - just simple alerts. Advice is appreciated.
