  • How to modify VBO data

    - by Romeo
    I am learning LWJGL so i can start working on my game. In order to learn LWJGL I got the idea to implement the map builder so I can get comfortable with graphics programming. Now, for the map creation tool I need to draw new elements or draw the old one's with different coordinates. Let me explain this: My game will be a 2D scroller. The map will be consisting of multiple rectangles ( 2 strip triangles). When I click my left-mouse button i want to start the rectangle and when I release it I want to stop the rectangle bottom-right at that position. As I want to use VBOs I want to know how to modify data inside the VBO based on user input. Should i have a copy of a vertex array and then add the whole array to the VBO at each user input? How is usually implemented the VBO update?

  • T-SQL Tuesday #34: Help! I Need Somebody!

    - by Most Valuable Yak (Rob Volk)
    Welcome everyone to T-SQL Tuesday Episode 34!  When last we tuned in, Mike Fal (b|t) hosted Trick Shots.  These highlighted techniques or tricks that you figured out on your own which helped you understand SQL Server better. This month, I'm asking you to look back this past week, year, century, or hour...to a time when you COULDN'T figure it out.  When you were stuck on a SQL Server problem and you had to seek help. In the beginning... SQL Server has changed a lot since I started with it.  <Cranky Old Guy> Back in my day, Books Online was neither.  There were no blogs. Google was the third-place search site. There were perhaps two or three community forums where you could ask questions.  (Besides the Microsoft newsgroups...which you had to access with Usenet.  And endure the wrath of...Celko.)  Your "training" was reading a book, made from real dead trees, that you bought from your choice of brick-and-mortar bookstore. And except for your local user groups, there were no conferences, seminars, SQL Saturdays, or any online video hookups where you could interact with a person. You'd have to call Microsoft Support...on the phone...a LANDLINE phone.  And none of this "SQL Family" business!</Cranky Old Guy> Even now, with all these excellent resources available, it's still daunting for a beginner to seek help for SQL Server.  The product is roughly 1247.4523 times larger than it was 15 years ago, and it's simply impossible to know everything about it.*  So whether you are a beginner, or a seasoned pro of over a decade's experience, what do you do when you need help on SQL Server? That's so meta... In the spirit of offering help, here are some suggestions for your topic: Tell us about a person or SQL Server community who have been helpful to you.  It can be about a technical problem, or not, e.g. someone who volunteered for your local SQL Saturday.  Sing their praises!  Let the world know who they are! Do you have any tricks for using Books Online?  Do you use the locally installed product, or are you completely online with BOL/MSDN/Technet, and why? If you've been using SQL Server for over 10 years, how has your help-seeking changed? Are you using Twitter, StackOverflow, MSDN Forums, or another resource that didn't exist when you started? What made you switch? Do you spend more time helping others than seeking help? What motivates you to help, and how do you contribute? Structure your post along the lyrics to The Beatles song Help! Audio or video renditions are particularly welcome! Lyrics must include reference to SQL Server terminology or community, and performances must be in your voice or include you playing an instrument. These are just suggestions, you are free to write whatever you like.  Bonus points if you can incorporate ALL of these into a single post.  (Or you can do multiple posts, we're flexible like that.)  Help us help others by showing how others helped you! Legalese, Your Rights, Yada yada... If you would like to participate in T-SQL Tuesday please be sure to follow the rules below: Your blog post must be published between Tuesday, September 11, 2012 00:00:00 GMT and Wednesday, September 12, 2012 00:00:00 GMT. Include the T-SQL Tuesday logo (above) and hyperlink it back to this post. If you don’t see your post in trackbacks, add the link to the comments below. If you are on Twitter please tweet your blog using the #TSQL2sDay hashtag.  I can be contacted there as @sql_r, in case you have questions or problems with comments/trackback.  I'll have a follow-up post listing all the contributions as soon as I can.

  • Webapps don't open correctly when using Chromium

    - by Alex
    I have just installed Ubuntu 12.10 completely fresh, the old version of Ubuntu was discarded or overwritten (or whatever you call it). I want to use the Ubuntu webapps with Chromium but I've had several problems. }The first problem is that Chromium won't ask me if I want to install a webapp if I go to a supported site (and I don't already have the webapp installed). The second problem is that when I install the webapp by visiting the site in Firefox, and then I try to open it in Chromium, Ubuntu will open a completely new Chromium icon and window in the Launcher, and the icon will be labeled "Untitled"; also there is no search bar in the new window, only the tab at the top. I've tried using several webapps with Firefox set as the default browser and they work as expected: once the webapp icon is clicked a Firefox window is opened on the Firefox launcher icon, and the window has 'new tab' button and search bar.

  • Can I hook my xbox up to my Ubuntu PC

    - by Anonymous John
    My old xbox 360 won't eject disks, it makes a sound,but won't open. I want to play games, so I think I could hook it up to my PC running Ubuntu 13.10 64-bit and maybe I could use my PC's DVD drive. Can this work at all, or am I just crazy? There is an HDMI port on the back of my graphics card. If I can't do that, is there any software for Ubuntu that can rip the game off of a CD and put it on a flash drive? I have heard xbmcbuntu works great for gaming, but it doesn't work with my PC.

  • Writing drivers for a printer?

    - by user828584
    My goal is to be able to fax 20 page pdf documents for free. I've looked online, and there are some free fax services, but all of them have their limits. I do have an old fax machine, but the documents that need to be faxed are on the computer, and to print them would be far from free. Unfortunately, the only way to send a fax with the machine is by scanning it. What's strange is that it can scan to the computer and print from it, but it won't fax from it... :(. Is it possible to write something (preferably C#, but it's going to take some learning anyway) that will allow me to send a fax from the computer? I have very little software experience, and none in anything like this, so I have no idea where to start. If it is possible, where can I find all the information needed to write the program?

  • Enterprise Trade Compliance: Changing Trade Operations around the World

    - by John Murphy
    We live in a world of incredible bounty and speed where any product can be delivered anywhere on earth. However, our world is also filled with challenges for business – where volatility, uncertainty, risk, and chaos are our daily companions. To prosper amid the realities of this new world, organizations cannot rely on old strategies; they need new business models. Key trends within the global economy are mandating that companies fully integrate global trade management best practices within broader supply chain management strategies, rather than simply leaving it as a discrete event at the end of the order or procurement cycle. To explain, many companies face a complicated and changing compliance environment. This is directly linked to the speed and configuration of the supply chain, particularly with the explosion of new markets, shorter service cycles and ship times, accelerating rates of globalization and outsourcing, and increasing product complexity and regulation.

  • NEON Intrinsic Support in CE7

    - by Kate Moss' Open Space
    Just a side note for people who may be interested in creating high performance code to take advantage on NEON instruction set but wish to use NEON intrinsic instaed of coding assembly. Compiler won't generate NEON opcode unless application use the NEON intrinsic explicitly. Basically, you need ARMv7 build enviroment, so compiler can emit NEON opcode. Intrinsic prototype can be found in public\COMMON\sdk\inc\arm_neon.h and that is all you got. If you ever find an NEON opcode does not have corresponding intrinsic, you still need to use the old trick - write that part of code in assembly.

  • FormatDate in Display Item Form Webpart

    - by H(at)Ni
    I've faced an issue that I wanted to display the date in the format of ('MMMM dd') that is retrieved from a sharepoint list in an arabic site collection. So, after googling this issue, I've found out that a possible solution to my poblem is using the function ddwrt:FormatDateTime that can be used as long as you'll include the following namespace xmlns:ddwrt="http://schemas.microsoft.com/WebParts/v2/DataView/runtime" My purpose was solved by writing this line of code in my xsl code behind for the webpart : ddwrt:FormatDateTime(string(@StartDate),3073,'MMMM dd') but that worked only if the webpart is inserted into an English site . After trying to search but in vain, I started to use my guesses that ended up doing something like that: ddwrt:FormatDateTime(ddwrt:FormatDateTime(string(@StartDate),3073,'dd/MM/yyyy'), 3073, 'MMMM dd') And the cause of the problem was that sharepoint parses the date as 'MM/dd/yyyy' which I think could be related to server regional settings, so I had to force it to parse the date in arabic-Egypt format as 'dd/MM/yyyy' in order to get the correct 'Month Day' format as expected.

  • Is Infiniband going to get squeezed by iWARP and external QPI?

    - by andy.grover
    The Inquirer certainly thinks so.However, I'm not so sure it makes sense to compare Infiniband to an as-yet-unannounced optical external QPI. QPI is currently a processor interconnect. CPUs, RAM, and devices connected by it are conceptually part of the same machine -- they run a single OS, for example. They are both "networks" or "fabrics" but they have very different design trade-offs.Another widely-used bus in the system is closer to Infiniband than QPI -- PCI Express. Isn't it more likely that PCIe could take on IB? There are companies already who have solutions that use external PCI Express for cluster interconnect, but these have not gained significant market share. Why would QPI, a technology whose sweet spot is even further from Infiniband's than PCIe, be able to challenge Infiniband? It's hard to speculate without much information, but right now it doesn't seem likely to me.The other prediction made in the article is that Intel's 10GbE iWARP card could squeeze IB on the low end, due to its greater compatibility and lower cost.It's definitely never a good idea to bet against Ethernet when it comes to mass-market, commodity networking. Ethernet will win. 10GbE will win. But, there are now two competing ways to implement the low-latency RDMA Verbs interface on top of Ethernet. iWARP is essentially RDMA over TCP/IP over Ethernet. The new alternative is IBoE (Infiniband over Ethernet, aka RoCEE, aka "Rocky"). This encapsulates the IB packet protocol directly in the Ethernet frame. It loses the layer 3 routability of iWARP, but better maintains software compatibility with existing apps that use IB, and is simpler to implement in both software and hardware. iWARP has a substantial head start, but I believe that IBoE silicon will eventually be cheaper, and more likely to be implemented in commodity Ethernet hardware.I think IBoE is going to take low-end market share from traditional IB, but I think this is a situation IB hardware vendors have no problem accepting. Commoditized IBoE NICs invite greater use of RDMA features, and when higher performance is needed, customers can upgrade to "real" IB, maintaining IB's justification for higher prices. (IB max interconnect speeds have historically been 2-4x higher than Ethernet, and I don't see that changing.)(ObDisclosure: My current employer now sells IB hardware. I previously also worked at Intel. My opinions are my own, duh.)

  • Escaping In Expressions

    The expressions language is a C style syntax, so you may need to escape certain characters, for example: "C:\FolderPath\" + @VariableName Should be "C:\\FolderPath\\" + @VariableName Another use of the escape sequence allows you to specify character codes, like this \xNNNN, where NNNN is the Unicode character code that you want. For example the following expression will produce the same result as the previous example as the Unicode character code 005C equals a back slash character: "C:\x005CFolderPath\x005C" + @VariableName For more information about Unicode characters see http://www.unicode.org/charts/ Literals are also supported within expressions, both string literals using the common escape sequence syntax as well as modifiers which influence the handling of numeric values. See the "Literals (SSIS)":http://msdn2.microsoft.com/en-US/library/ms141001(SQL.90).aspx topic. Using the Unicode escaped character sequence you can make up for the lack of a CHAR function or equivalent.

  • Does anyone prefer proportional fonts?

    - by Jason Baker
    I was reading the wikipedia article on programming style and noticed something in an argument against vertically aligned code: Reliance on mono-spaced font; tabular formatting assumes that the editor uses a fixed-width font. Most modern code editors support proportional fonts, and the programmer may prefer to use a proportional font for readability. To be honest, I don't think I've ever met a programmer who preferred a proportional font. Nor can I think of any really good reasons for using them. Why would someone prefer a proportional font?

  • How to leverage the internal HTTP endpoint available on Azure web roles?

    - by Alfredo Delsors
    Imagine you have a Web application using an in-memory collection that changes occasionally but is used very often. The collection gets loaded from storage on the Application_Start global.asax event and is updated whenever its content changes. If you want to deploy this application on Azure you need to keep in mind that more than one instance of the application can be running at any time and therefore you need to provide some mechanism to keep all instances informed with the latest changes. Because the communication through internal endpoints between Azure role instances is at no cost, a good solution can be maintaining the information on Azure Storage Tables, reading its contents on the Application_Start event and populating its changes to all other instances using the internal HTTP port available on Azure Web Roles. You need to follow these steps to leverage the internal HTTP endpoint available on Azure web roles to maintain all instances up to date. 1.   Define an internal HTTP endpoint in the Web Role properties, for example InternalHttpEndpoint   2.   Add a new WCF service to the Web Role, for example NotificationService.svc 3.   Disable multiple site bindings in web.config: <serviceHostingEnvironment multipleSiteBindingsEnabled="false"> 4.   Add a method on the new service to receive notifications from other role instances. namespace Service { [ServiceContract] public interface INotificationService { [OperationContract(IsOneWay = true)] void Notify(Information info); } } 5.   Declare a class that inherits from System.ServiceModel.Activation.ServiceHostFactory and override the method CreateServiceHost to host the internal endpoint. public class InternalServiceFactory : ServiceHostFactory { protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { var internalEndpointAddress = string.Format( "http://{0}/NotificationService.svc", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["InternalHttpEndpoint"].IPEndpoint); ServiceHost host = new ServiceHost( typeof(NotificationService), new Uri(internalEndpointAddress)); BasicHttpBinding binding = new BasicHttpBinding(SecurityMode.None); host.AddServiceEndpoint( typeof(INotificationService), binding, internalEndpointAddress); return host; } } Note that you can use SecurityMode.None because the internal endpoint is private to the instances of the service. 6.   Edit the markup of the service right clicking the svc file and selecting "View markup" to add the new factory as the factory to be used to create the service <%@ ServiceHost Language="C#" Debug="true" Factory="Service.InternalServiceFactory" Service="Service.NotificationService" CodeBehind="NotificationService.svc.cs" %> 7.   Now you can notify changes to other instances using this code: var current = RoleEnvironment.CurrentRoleInstance; var endPoints = current.Role.Instances .Where(instance => instance != current) .Select(instance => instance.InstanceEndpoints["InternalHttpEndpoint"]); foreach (var ep in endPoints) { EndpointAddress address = new EndpointAddress( String.Format("http://{0}/NotificationService.svc", ep.IPEndpoint)); BasicHttpBinding binding = new BasicHttpBinding(SecurityMode.None); var factory = new ChannelFactory<INotificationService>(binding); INotificationService instance = factory.CreateChannel(address); instance.Notify(changedinfo); }

  • I want to master ASP.NET - What concepts should I focus on/What concepts do you most value?

    - by Josh
    I start a job this summer doing work in ASP.NET 4 (C#). I plan on working with some legacy code as well as MVC. I want to get a running start. I have good understanding of HTML/CSS/Javascript, and pretty good understanding of C# itself, Design principles, Design Patterns, and understand masterpages, basic MVC2, and code behinds for web forms. In your opinion what aspects of ASP.NET are the most important to master for web applications? What do you value most in your usage of ASP.NET? Do you have a recommendation for understanding the internals of ASP.NET itself?

  • A brief note for customers running SOA Suite on AIX platforms

    - by christian
    When running Oracle SOA Suite with IBM JVMs on the AIX platform, we have seen performance slowdowns and/or memory leaks. On occasion, we have even encountered some OutOfMemoryError conditions and the concomittant Java coredump. If you are experiencing this issue, the resolution may be to configure -Dsun.reflect.inflationThreshold=0 in your JVM startup parameters. https://www.ibm.com/developerworks/java/library/j-nativememory-aix/ contains a detailed discussion of the IBM AIX JVM memory model, but I will summarize my interpretation and understanding of it in the context of SOA Suite, below. Java ClassLoaders on IBM JVMs are allocated a native memory area into which they are anticipated to map such things as jars loaded from the filesystem. This is an excellent memory optimization, as the file can be loaded into memory once and then shared amongst many JVMs on the same host, allowing for excellent horizontal scalability on AIX hosts. However, Java ClassLoaders are not used exclusively for loading files from disk. A performance optimization by the Oracle Java language developers enables reflectively accessed data to optimize from a JNI call into Java bytecodes which are then amenable to hotspot optimizations, amongst other things. This performance optimization is called inflation, and it is executed by generating a sun.reflect.DelegatingClassLoader instance dynamically to inject the Java bytecode into the virtual machine. It is generally considered an excellent optimization. However, it interacts very negatively with the native memory area allocated by the IBM JVM, effectively locking out memory that could otherwise be used by the Java process. SOA Suite and WebLogic are both very large users of reflection code. They reflectively use many code paths in their operation, generating lots of DelegatingClassLoaders in normal operation. The IBM JVM slowdown and subsequent OutOfMemoryError are as a direct result of the Java memory consumed by the DelegatingClassLoader instances generated by SOA Suite and WebLogic. Java garbage collection runs more frequently to try and keep memory available, until it can no longer do so and throws OutOfMemoryError. The setting sun.reflect.inflationThreshold=0 disables this optimization entirely, never allowing the JVM to generate the optimized reflection code. IBM JVMs are susceptible to this issue primarily because all Java ClassLoaders have this native memory allocation, which is shared with the regular Java heap. Oracle JVMs don't automatically give all ClassLoaders a native memory area, and my understanding is that jar files are never mapped completely from shared memory in the same way as IBM does it. This results in different behaviour characteristics on IBM vs Oracle JVMs.

  • Migrating Core Data to new UIManagedDocument in iOS 5

    - by samerpaul
    I have an app that has been on the store since iOS 3.1, so there is a large install base out there that still uses Core Data loaded up in my AppDelegate. In the most recent set of updates, I raised the minimum version to 4.3 but still kept the same way of loading the data. Recently, I decided it's time to make the minimum version 5.1 (especially with 6 around the corner), so I wanted to start using the new fancy UIManagedDocument way of using Core Data. The issue with this though is that the old database file is still sitting in the iOS app, so there is no migrating to the new document. You have to basically subclass UIManagedDocument with a new model class, and override a couple of methods to do it for you. Here's a tutorial on what I did for my app TimeTag.  Step One: Add a new class file in Xcode and subclass "UIManagedDocument" Go ahead and also add a method to get the managedObjectModel out of this class. It should look like:   @interface TimeTagModel : UIManagedDocument   - (NSManagedObjectModel *)managedObjectModel;   @end   Step two: Writing the methods in the implementation file (.m) I first added a shortcut method for the applicationsDocumentDirectory, which returns the URL of the app directory.  - (NSURL *)applicationDocumentsDirectory {     return [[[NSFileManagerdefaultManager] URLsForDirectory:NSDocumentDirectoryinDomains:NSUserDomainMask] lastObject]; }   The next step was to pull the managedObjectModel file itself (.momd file). In my project, it's called "minimalTime". - (NSManagedObjectModel *)managedObjectModel {     NSString *path = [[NSBundlemainBundle] pathForResource:@"minimalTime"ofType:@"momd"];     NSURL *momURL = [NSURL fileURLWithPath:path];     NSManagedObjectModel *managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:momURL];          return managedObjectModel; }   After that, I need to check for a legacy installation and migrate it to the new UIManagedDocument file instead. This is the overridden method: - (BOOL)configurePersistentStoreCoordinatorForURL:(NSURL *)storeURL ofType:(NSString *)fileType modelConfiguration:(NSString *)configuration storeOptions:(NSDictionary *)storeOptions error:(NSError **)error {     // If legacy store exists, copy it to the new location     NSURL *legacyPersistentStoreURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"minimalTime.sqlite"];          NSFileManager* fileManager = [NSFileManagerdefaultManager];     if ([fileManager fileExistsAtPath:legacyPersistentStoreURL.path])     {         NSLog(@"Old db exists");         NSError* thisError = nil;         [fileManager replaceItemAtURL:storeURL withItemAtURL:legacyPersistentStoreURL backupItemName:niloptions:NSFileManagerItemReplacementUsingNewMetadataOnlyresultingItemURL:nilerror:&thisError];     }          return [superconfigurePersistentStoreCoordinatorForURL:storeURL ofType:fileType modelConfiguration:configuration storeOptions:storeOptions error:error]; }   Basically what's happening above is that it checks for the minimalTime.sqlite file inside the app's bundle on the iOS device.  If the file exists, it tells you inside the console, and then tells the fileManager to replace the storeURL (inside the method parameter) with the legacy URL. This basically gives your app access to all the existing data the user has generated (otherwise they would load into a blank app, which would be disastrous). It returns a YES if successful (by calling it's [super] method). Final step: Actually load this database Due to how my app works, I actually have to load the database at launch (instead of shortly after, which would be ideal). I call a method called loadDatabase, which looks like this: -(void)loadDatabase {     static dispatch_once_t onceToken;          // Only do this once!     dispatch_once(&onceToken, ^{         // Get the URL         // The minimalTimeDB name is just something I call it         NSURL *url = [[selfapplicationDocumentsDirectory] URLByAppendingPathComponent:@"minimalTimeDB"];         // Init the TimeTagModel (our custom class we wrote above) with the URL         self.timeTagDB = [[TimeTagModel alloc] initWithFileURL:url];           // Setup the undo manager if it's nil         if (self.timeTagDB.undoManager == nil){             NSUndoManager *undoManager = [[NSUndoManager  alloc] init];             [self.timeTagDB setUndoManager:undoManager];         }                  // You have to actually check to see if it exists already (for some reason you can't just call "open it, and if it's not there, create it")         if ([[NSFileManagerdefaultManager] fileExistsAtPath:[url path]]) {             // If it does exist, try to open it, and if it doesn't open, let the user (or at least you) know!             [self.timeTagDB openWithCompletionHandler:^(BOOL success){                 if (!success) {                     // Handle the error.                     NSLog(@"Error opening up the database");                 }                 else{                     NSLog(@"Opened the file--it already existed");                     [self refreshData];                 }             }];         }         else {             // If it doesn't exist, you need to attempt to create it             [self.timeTagDBsaveToURL:url forSaveOperation:UIDocumentSaveForCreatingcompletionHandler:^(BOOL success){                 if (!success) {                     // Handle the error.                     NSLog(@"Error opening up the database");                 }                 else{                     NSLog(@"Created the file--it did not exist");                     [self refreshData];                 }             }];         }     }); }   If you're curious what refreshData looks like, it sends out a NSNotification that the database has been loaded: -(void)refreshData {     NSNotification* refreshNotification = [NSNotificationnotificationWithName:kNotificationCenterRefreshAllDatabaseData object:self.timeTagDB.managedObjectContext  userInfo:nil];     [[NSNotificationCenter defaultCenter] postNotification:refreshNotification];     }   The kNotificationCenterRefreshAllDatabaseData is just a constant I have defined elsewhere that keeps track of all the NSNotification names I use. I pass the managedObjectContext of the newly created file so that my view controllers can have access to it, and start passing it around to one another. The reason we do this as a Notification is because this is being run in the background, so we can't know exactly when it finishes. Make sure you design your app for this! Have some kind of loading indicator, or make sure your user can't attempt to create a record before the database actually exists, because it will crash the app.

  • Assets.getBytes returns null in test environment

    - by ashes999
    I'm using the latest Haxe (2.10), NME (3.4.3), and MUnit. I've written some unit tests that need to fetch bitmap data from SWF symbols. The first step is to actually load the SWF data. To do this, I use NME's getByteArray along with the swf library, like so: var blah:SWF = new SWF(Assets.getBytes("assets/swf/test.swf")); The call to Assets.getBytes returns null when I'm running this under MUnit. When running my actual game code, I'm able to get the byte array (and consequentially, instantiate the SWF class). Am I doing something wrong? What am I missing? Edit: My directory structure is: . (root .\assets .\assets\*.png (other images) .\assets\swf\*.swf (SWFs) .\Source\*.hx (source code) .\Test\*.hx (tests)

  • Is it ok to initialize an RB_ConstraintActor in PostBeginPlay?

    I have a KActorSpawnable subclass that acts weird. In PostBeginPlay, I initialize an RB_ConstraintActor; the default is not to allow rotation. If I create one in the editor, it's fine, and won't rotate. If I spawn one, it rotates. Here's the class: class QuadForceKActor extends KActorSpawnable placeable; var(Behavior) bool bConstrainRotation; var(Behavior) bool bConstrainX; var(Behavior) bool bConstrainY; var(Behavior) bool bConstrainZ; var RB_ConstraintActor PhysicsConstraintActor; simulated event PostBeginPlay() { Super.PostBeginPlay(); PhysicsConstraintActor = Spawn(class'RB_ConstraintActorSpawnable', self, '', Location, rot(0, 0, 0)); if(bConstrainRotation) { PhysicsConstraintActor.ConstraintSetup.bSwingLimited = true; PhysicsConstraintActor.ConstraintSetup.bTwistLimited = true; } SetLinearConstraints(bConstrainX, bConstrainY, bConstrainZ); PhysicsConstraintActor.InitConstraint(self, None); } function SetLinearConstraints(bool InConstrainX, bool InConstrainY, bool InConstrainZ) { if(InConstrainX) { PhysicsConstraintActor.ConstraintSetup.LinearXSetup.bLimited = 1; } else { PhysicsConstraintActor.ConstraintSetup.LinearXSetup.bLimited = 0; } if(InConstrainY) { PhysicsConstraintActor.ConstraintSetup.LinearYSetup.bLimited = 1; } else { PhysicsConstraintActor.ConstraintSetup.LinearYSetup.bLimited = 0; } if(InConstrainZ) { PhysicsConstraintActor.ConstraintSetup.LinearZSetup.bLimited = 1; } else { PhysicsConstraintActor.ConstraintSetup.LinearZSetup.bLimited = 0; } } DefaultProperties { bConstrainRotation=true bConstrainX=false bConstrainY=false bConstrainZ=false bSafeBaseIfAsleep=false bNoEncroachCheck=false } Here's the code I use to spawn one. It's a subclass of the one above, but it doesn't reference the constraint at all. local QuadForceKCreateBlock BlockActor; BlockActor = spawn(class'QuadForceKCreateBlock', none, 'PowerCreate_Block', BlockLocation(), m_PreparedRotation, , false); BlockActor.SetDuration(m_BlockDuration); BlockActor.StaticMeshComponent.SetNotifyRigidBodyCollision(true); BlockActor.StaticMeshComponent.ScriptRigidBodyCollisionThreshold = 0.001; BlockActor.StaticMeshComponent.SetStaticMesh(m_ValidCreationBlock.StaticMesh); BlockActor.StaticMeshComponent.AddImpulse(m_InitialVelocity); I used to initialize an RB_ConstraintActor where I spawned it from the outside. This worked, which is why I'm pretty sure it has nothing to do with the other code in QuadForceKCreateBlock. I then added the internal constraint in QuadForceKActor for other purposes. When I realized I had two constraints on the CreateBlock doing the same thing, I removed the constraint code from the place where I spawn it. Then it started rotating. Is there a reason I should not be initializing an RB_ConstraintActor in PostBeginPlay? I feel like there's some basic thing about how the engine works that I'm missing.

  • What ever happened to the Google AJAX Search API

    - by John
    I am looking to query the main Google search however all references including stackoveflow point to the Google AJAX Search API. The odd thing is that it does not seem to exist any more not even a note to say it is depreciated? The old links point to main Google code site. If I look at the list of API's on that site the API it replaced is there Web Search API (Deprecated) which links back to same page but not the Google AJAX Search API. Further Google searching is not being helpful either, many blog posts pointing to the same Google site (http://code.google.com/apis/ajaxsearch/) that has no content and redirects to the same place? Just to prove it did exist I have found it on the way back machine however the last snapshot did not show any special unusual message.

  • have a missing file, and cant run ubuntu upon start up, and hasnt the flash drive i used didnt work either, any help?

    - by trent
    when I first downloaded Ubuntu to install it, it downloaded quick and caused no problems to my laptop. but then when it came time to install it as one of my operating systems, it wouldn't run because it said a file was missing or damaged. so then I uninstalled it and re-installed it but I still had that same problem. so I tried a flash-drive version but that didn't work either because it wouldn't boot from that, nor would it detect my flash drive, (in this case, an old 4 GB mp3 player). any help or tips and ideas would be great, I just need a decent operating system because windows is getting to be terrible at the moment, just note I wanna run Ubuntu along side windows 8.1

  • Is there a real name policy in the Ubuntu community?

    - by martin001
    I'm not ashamed to be a part of Ubuntu, but I'm trying to keep the number of web search hits for my real name low, which is kinda impossible if you use a Launchpad account. So, I'm wondering if there is a real name policy in the Ubuntu community, or if it's okay to use a pseudonym/nick name/fake name? While it might be okay to use nick names on IRC and in forums, how about these topics: Adding an OpenPGP key to Launchpad. Signing the Ubuntu Code of Conduct. Becoming an Ubuntu member. Code contributions (e.g., signing the Canonical CLA). Thanks in advance for your answers!

    Hi, i'm trying to set up fstab to automatically connect to my office shared server. I'm undoubtedly doing something silly here as the username and password and server name work fine in the first code snippet below, just not the second - any help would be appreciated! The following command works as expected... tom@tom-desktop: sudo /usr/bin/smbclient -L Server.local -Uguest Enter guest's password: Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.10] Sharename Type Comment --------- ---- ------- Lacie Disk Disk macosx Server Disk macosx IPC$ IPC IPC Service (Server) ADMIN$ IPC IPC Service (Server) Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.10] Server Comment --------- ------- ACER-9D60040D10 SERVER Server Workgroup Master --------- ------- WORKGROUP ACER-9D60040D10 But when i add the following line to /etc/fstab, i get this error: cifs_mount failed w/return code = -22 //Server.local/Server /media/maguires cifs username=guest,password=password 0 0

  • 80% off for SQL Azure!

    - by Hugo Kornelis
    I have spent the last three days at SQLBits X in London – a truly great experience! There were lots of quality sessions, but I also enjoyed meeting new people and catching up with old friends. One of these friends (and I hope he’s still a friend after I post this) is Buck Woody . Not only a great and humorous speaker, but also a very nice fellow – for those who don’t mind being teased every now and then. When we were chatting, he told me that he was planning to announce a special access code to allow...(read more)
