  • In what kind of variable type is the player position stored on a MMORPG such as WoW?

    - by jokoon
    I even heard J. Carmack quickly talk about it... How a software can track a player's position so accurately, being on a such huge world, without loading between zones, and on a multiplayer scale ? How is the data formatted when it passes through the netcode ? I can understand how vertices are stored into the graphic card's memory, but when it comes to synchronize the multiplayer, I can't imagine what is best.

  • which is better performance, using a disposable local variable or reusing a global one?

    - by petervaz
    This is for an android game. Suppose I have a function that is called several times for second and do some calculations involving an arraylist (or any other complex objects for what matter). Which approach would be preffered? local: private void doStuff(){ ArrayList<Type> XList = new ArrayList<Type>(); // do stuff with list } global: private ArrayList<Type> XList = new ArrayList<Type>(); private void doStuff(){ XList.clear(); // do stuff with list }

  • Removing/Adding a specific variable from an object inside javascript array? [migrated]

    - by hustlerinc
    I have a map array with objects stuffed with variables looking like this: var map = [ [{ground:0, object:1}, {ground:0, item:2}, {ground:0, object:1, item:2}], [{ground:0, object:1}, {ground:0, item:2}, {ground:0, object:1, item:2}] ]; Now I would like to be able to delete and add one of the variables like item:2. 1) What would I use to delete specific variables? 2) What would I use to add specific variables? I just need 2 short lines of code, the rest like detecting if and where to execute I've figured out. I've tried delete map[i][j].item; with no results. Help appreciated.

  • What's the point of initializing a variable with the same value twice?

    - by JoeM05
    I was reading Ben Cherry's "JavaScript Module Pattern: In-Depth", and he had some example code that I didn't quite understand. Under the Cross-File Private State heading, there is some example code that has the following: var _private = my._private = my._private || {} This doesn't seem to be different from writing something like this: var _private = my._private || {} What's happening here and how are these two declarations different?

  • Store product data in session variable or access db every time?

    - by JakeTheSnake
    I have my database storing lots of information about products (year, name, release_date, volume, etc. etc.). I currently load all of the products once and store them in a session variable - right now there's only 8 products but the list will grow as time progresses. The reason why I did this was to (perhaps foolishly) save HDD reads every time the products page was accessed. Am I shooting myself in the foot by storing this information in the session?

  • Is it justified to use project-wide unique function and variable names to help future refactoring?

    - by kahoon
    Refactoring tools (like ReSharper) often can't be sure whether to rename a given identifier when, for example refactoring a JavaScript function. I guess this is a consequence of JavaScript's dynamic nature. ReSharper solves this problem by offering to rename reasonable lexical matches too. The developer can opt out of renaming certain functions, if he finds that the lexical match is purely accidental. This means that the developer has to approve every instance that will be affected by the renaming. For example let's consider we have two Backbone classes which are used completely independently from each other in our application: var Header = Backbone.View.extend({ close: function() {...} }) var Dialog = Backbone.View.extend({ close: function() {...} }) If you try to rename Dialog's close method to for example closeAndNotify, then ReSharper will offer to rename all occurences of Header's close method just because they are the same lexically prior to the renaming. To avoid this problem, please consider this: var Header = Backbone.View.extend({ closeHeader: function() {...} }) var Dialog = Backbone.View.extend({ closeDialog: function() {...} }) Now you can rename closeDialog unambiguously - given that you have no other classes having a method with the same name. Is it worth it to name my functions this way to help future refactoring?

  • Decrementing/Incrementing loop variable inside for loop. Is this code smell?

    - by FairDune
    I have to read lines from a text file in sequential order. The file is a custom text format that contains sections. If some sections are out of order, I would like to look for the starting of the next valid section and continue processing. Currently, I have some code that looks like this: for (int currentLineIndex=0; currentLineIndex < lines.Count; currentLineIndex++ ) { //Process section here if( out_of_order_condition ) { currentLineIndex--;//Stay on the same line in the next iteration because this line may be the start of a valid section. continue; } } Is this code smell?

  • How to check if a variable is an integer? [closed]

    - by FyrePlanet
    I'm going through my C++ book and have currently made a working Guess The Number game. The game generates a random number based on current time, has the user input their guess, and then tells them whether it was too high, too low, or the correct number. The game functions fine if you enter a number, but returns 'Too High' if you enter something that is not a number (such as a letter or punctuation). Not only does it return 'too high', but it also continually returns it. I was wondering what I could do to check if the guess, as input by the user, is an integer and if it is not, to return 'Not a number. Guess again.' Here is the code. #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main() { srand(time(0)); // seed the random number generator int theNumber = rand() % 100 + 1; // random number between 1 and 100 int tries = 0, guess; cout << "\tWelcome to Guess My Number!\n\n"; do { cout << "Enter a guess: "; cin >> guess; ++tries; if (guess > theNumber) cout << "Too high!\n\n"; if (guess < theNumber) cout << "Too low!\n\n"; } while (guess != theNumber); cout << "\nThat's it! You got it in " << tries << " guesses!\n"; cout << "\nPress Enter to exit.\n"; cin.ignore(cin.rdbuf()->in_avail() + 1); return 0; }

  • WPF binding to ComboBox SelectedItem when reference not in ItemsSource.

    - by juharr
    I'm binding the PageMediaSize collection of a PrintQueue to the ItemSource of a ComboBox (This works fine). Then I'm binding the SelectedItem of the ComboBox to the DefaultPrintTicket.PageMediaSize of the PrintQueue. While this will set the selected value to the DefaultPrintTicket.PageMediaSize just fine it does not set the initially selected value of the ComboBox to the initial value of DefaultPrintTicket.PageMediaSize This is because the DefaultPrintTicket.PageMediaSize reference does not match any of the references in the collection. However I don't want it to compare the objects by reference, but instead by value, but PageMediaSize does not override Equals (and I have no control over it). What I'd really like to do is setup a IComparable for the ComboBox to use, but I don't see any way to do that. I've tried to use a Converter, but I would need more than the value and I couldn't figured out how to pass the collection to the ConverterProperty. Any ideas on how to handle this problem. Here's my xaml <ComboBox x:Name="PaperSizeComboBox" ItemsSource="{Binding ElementName=PrintersComboBox, Path=SelectedItem, Converter={StaticResource printQueueToPageSizesConverter}}" SelectedItem="{Binding ElementName=PrintersComboBox, Path=SelectedItem.DefaultPrintTicket.PageMediaSize}" DisplayMemberPath="PageMediaSizeName" Height="22" Margin="120,76,15,0" VerticalAlignment="Top"/> And the code for the converter that gets the PageMediaSize collection public class PrintQueueToPageSizesConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return value == null ? null : ((PrintQueue)value).GetPrintCapabilities().PageMediaSizeCapability; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } }

  • Using Directives, Namespace and Assembly Reference - all jumbled up with StyleCop!

    - by Jack
    I like to adhere to StyleCop's formatting rules to make code nice and clear, but I've recently had a problem with one of its warnings: All using directives must be placed inside of the namespace. My problem is that I have using directives, an assembly reference (for mocking file deletion), and a namespace to juggle in one of my test classes: using System; using System.IO; using Microsoft.Moles.Framework; using Microsoft.VisualStudio.TestTools.UnitTesting; [assembly: MoledType(typeof(System.IO.File))] namespace MyNamespace { //Some Code } The above allows tests to be run fine - but StyleCop complains about the using directives not being inside the namespace. Putting the usings inside the namespace gives the error that "MoledType" is not recognised. Putting both the usings and the assembly reference inside the namespace gives the error 'assembly' is not a valid attribute location for this declaration. Valid attribute locations for this declaration are 'type'. All attributes in this block will be ignored. It seems I've tried every layout I can but to no avail - either the solution won't build, the mocking won't work or StyleCop complains! Does anyone know a way to set these out so that everything's happy? Or am I going to have to ignore the StyleCop warning in this case?

  • How do I reference an unsigned assembly from a VSTO Word Doc project?

    - by Gishu
    I created a new project in VS2008. Project type Visual C# > Office > 2007 > Word 2007 Document Added some code.. got Word to do a few jumps through some custom hoops.. all fine. Now I need to reference another assembly (CopyLocal as false) which is not signed. So I add the project reference. Now the project will not build complaining error MSB3188: Assembly 'X.dll' must be strong signed in order to be marked as a prerequisite. The error code page is concise (now accustomed to this) Been googling and reading posts ever since.. No Luck. How do I get around this ? Or is the hidden commandment that all references (for VSTO?) must be strong named / signed. I cannot sign 'X.dll' and be done with it because it is a binary that I don't control also it depends on another bunch of unsigned dlls.. can't set off a chain sign reaction. Update: Solved the build issue by turning CopyLocal=True. But this meant dumping the referenced X.DLL and all its dependencies into the bin\debug folder... Ughh! Tried creating a subfolder called bin\debug\refExecs and referencing X.dll CopyLocal=false from there. The error message was back.

    Hello, I get this exception on my Windows 7 64bit in application running in VS 2008 express. I am using Connector/Net 6.2.2.0: Message: Object reference not set to an instance of an object. Source: MySql.Data in MySql.Data.MySqlClient.NativeDriver.GetResult(Int32& affectedRow, Int32& insertedId) Stack trace: in MySql.Data.MySqlClient.Driver.GetResult(Int32 statementId, Int32& affectedRows, Int32& insertedId) in MySql.Data.MySqlClient.Driver.NextResult(Int32 statementId) in MySql.Data.MySqlClient.MySqlDataReader.NextResult() in MySql.Data.MySqlClient.MySqlDataReader.Close() in MySql.Data.MySqlClient.MySqlConnection.Close() in MySql.Data.MySqlClient.MySqlConnection.Dispose(Boolean disposing) in System.ComponentModel.Component.Finalize() No inner exception. This exception is unhalted and the debugger dont point on any code line. It just say "Object reference not set to an instance of an object. MySql.Data" This error is really hard to repeat. On my Windows XP 32bit is all ok. Could it be error in 64bit Windows 7? Thank you very much for your answers. Regards, simon

  • Function parameters evaluation order: is undefined behaviour if we pass reference?

    - by bolov
    This is undefined behaviour: void feedMeValue(int x, int a) { cout << x << " " << a << endl; } int main() { int a = 2; int &ra = a; feedMeValue(ra = 3, a); return 0; } because depending on what parameter gets evaluated first we could call (3, 2) or (3, 3). However this: void feedMeReference(int x, int const &ref) { cout << x << " " << ref << endl; } int main() { int a = 2; int &ra = a; feedMeReference(ra = 3, a); return 0; } will always output 3 3 since the second parameter is a reference and all parameters have been evaluated before the function call, so even if the second parameter is evaluated before of after ra = 3, the function received a reference to a wich will have a value of 2 or 3 at the time of the evaluation, but will always have the value 3 at the time of the function call. Is the second example UB? It is important to know because the compiler is free to do anything if he detects undefined behaviour, even if I know it would always yield the same results. *Note: I think that feedMeReference(a = 3, a) is the exact same situation as feedMeReference(ra = 3, a). However it seems not everybody agrees, in the addition to having 2 completely different answers.

  • Is there a way to increase the efficiency of shared_ptr by storing the reference count inside the co

    - by BillyONeal
    Hello everyone :) This is becoming a common pattern in my code, for when I need to manage an object that needs to be noncopyable because either A. it is "heavy" or B. it is an operating system resource, such as a critical section: class Resource; class Implementation : public boost::noncopyable { friend class Resource; HANDLE someData; Implementation(HANDLE input) : someData(input) {}; void SomeMethodThatActsOnHandle() { //Do stuff }; public: ~Implementation() { FreeHandle(someData) }; }; class Resource { boost::shared_ptr<Implementation> impl; public: Resource(int argA) explicit { HANDLE handle = SomeLegacyCApiThatMakesSomething(argA); if (handle == INVALID_HANDLE_VALUE) throw SomeTypeOfException(); impl.reset(new Implementation(handle)); }; void SomeMethodThatActsOnTheResource() { impl->SomeMethodThatActsOnTheHandle(); }; }; This way, shared_ptr takes care of the reference counting headaches, allowing Resource to be copyable, even though the underlying handle should only be closed once all references to it are destroyed. However, it seems like we could save the overhead of allocating shared_ptr's reference counts and such separately if we could move that data inside Implementation somehow, like boost's intrusive containers do. If this is making the premature optimization hackles nag some people, I actually agree that I don't need this for my current project. But I'm curious if it is possible.

  • Drupal 6: getting particular fields from Node Reference types...

    - by artmania
    Hi friends, I'm a drupal newbie... <?php print $node->field_date[0]['view']; ?> I can get the custom created CCK fields' value and display in tpl.php files as above... that's fine. my question is how can I get the Node reference fields' in-fields? for example, I have an event content type, and I have defined Node Reference for Location (title, address, img, etc.). When I write the code below, it displays all location content; <?php print $node->field_location[0]['view']; ?> but I need to get only address field from this location content type. sth like below would be great :D but not working; <?php print $node->field_location[0]['field_address']['view']; ?> so how can get that? appreciate helps so much! thanks a lot!

  • Strict pointer aliasing: is access through a 'volatile' pointer/reference a solution?

    - by doublep
    On the heels of a specific problem, a self-answer and comments to it, I'd like to understand if it is a proper solution, workaround/hack or just plain wrong. Specifically, I rewrote code: T x = ...; if (*reinterpret_cast <int*> (&x) == 0) ... As: T x = ...; if (*reinterpret_cast <volatile int*> (&x) == 0) ... with a volatile qualifier to the pointer. Let's just assume that treating T as int in my situation makes sense. Does this accessing through a volatile reference solve pointer aliasing problem? For a reference, from specification: [ Note: volatile is a hint to the implementation to avoid aggressive optimization involving the object because the value of the object might be changed by means undetectable by an implementation. See 1.9 for detailed semantics. In general, the semantics of volatile are intended to be the same in C++ as they are in C. — end note ] EDIT: The above code did solve my problem at least on GCC 4.5.

  • Is this reference or code in mistake or bug?

    - by mikezang
    I copied some text from NSDate Reference as below, please check Return Value, it is said the format will be in YYYY-MM-DD HH:MM:SS ±HHMM, but I got as below in my app, so the reference is mistake? or code in mistake? Saturday, January 1, 2011 12:00:00 AM Japan Standard Time or 2011?1?1????0?00?00? ????? descriptionWithLocale: Returns a string representation of the receiver using the given locale. - (NSString *)descriptionWithLocale:(id)locale Parameters locale An NSLocale object. If you pass nil, NSDate formats the date in the same way as the description method. On Mac OS X v10.4 and earlier, this parameter was an NSDictionary object. If you pass in an NSDictionary object on Mac OS X v10.5, NSDate uses the default user locale—the same as if you passed in [NSLocale currentLocale]. Return Value A string representation of the receiver, using the given locale, or if the locale argument is nil, in the international format YYYY-MM-DD HH:MM:SS ±HHMM, where ±HHMM represents the time zone offset in hours and minutes from GMT (for example, “2001-03-24 10:45:32 +0600”)

  • Is it possible, in ASP.net, to reference private assembly in a non-virtual subdirectory?

    - by Bago
    Is it possible to reference a private assembly in asp .net from a sub-folder that is not setup as a virtual directory? In other words, my page is setup in ~/subdir, I don't have access to ~/, and I am not an IIS admin. Can I reference a private assembly? How would I do this? I've tried <%@ Assembly Src="/subdir/bin/Assembly.dll % and <%@ Assembly Src="/subdir/bin/Assembly.dll % , but I get the messages "There is no build provider to match the extension .dll" or "Failed to map to path" respectively. Here is my folder structure: / | -subdir | | - Bin | | | *Assembly.dll | | *Default.aspx I've heard that in web.config might do the trick, but when I've tried it, it doesn't seem to work. Furthermore, I've read that only works in the application .config file. (i.e., the one in ~/). Anyhow, I already tried adding the following to web.config: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="/subdir/bin" /> <dependentAssembly> <codeBase href="/subdir/bin/Assembly.dll"/> </dependentAssembly> </assemblyBinding> For more background on my problem, I am simply using a shared host, all I have is access to is that subdirectory, and I am trying to use fckeditor.

  • Are vector assignments copied by value or by reference in Google's Go language?

    - by Brian T Hannan
    In the following code, I create one peg puzzle then do a move on it which adds a move to its movesAlreadyDone vector. Then I create another peg puzzle then do a move on it which adds a move to its movesAlreadyDone vector. When I print out the values in that vector for the second one, it has the move in it from the first one along with the move from the second one. Can anyone tell me why it seems to be assigning by reference and not value? Are vector assignments copied by value or by reference in Google's Go language? package main import "fmt" import "container/vector" type Move struct { x0, y0, x1, y1 int } type PegPuzzle struct { movesAlreadyDone * vector.Vector; } func (p *PegPuzzle) InitPegPuzzle(){ p.movesAlreadyDone = vector.New(0); } func NewChildPegPuzzle(parent *PegPuzzle) *PegPuzzle{ retVal := new(PegPuzzle); retVal.movesAlreadyDone = parent.movesAlreadyDone; return retVal } func (p *PegPuzzle) doMove(move Move){ p.movesAlreadyDone.Push(move); } func (p *PegPuzzle) printPuzzleInfo(){ fmt.Printf("-----------START----------------------\n"); fmt.Printf("moves already done: %v\n", p.movesAlreadyDone); fmt.Printf("------------END-----------------------\n"); } func main() { p := new(PegPuzzle); cp1 := new(PegPuzzle); cp2 := new(PegPuzzle); p.InitPegPuzzle(); cp1 = NewChildPegPuzzle(p); cp1.doMove(Move{1,1,2,3}); cp1.printPuzzleInfo(); cp2 = NewChildPegPuzzle(p); cp2.doMove(Move{3,2,5,1}); cp2.printPuzzleInfo(); } Any help will be greatly appreciated.

  • why no implicit conversion from pointer to reference to const pointer.

    - by user316606
    I'll illustrate my question with code: #include <iostream> void PrintInt(const unsigned char*& ptr) { int data = 0; ::memcpy(&data, ptr, sizeof(data)); // advance the pointer reference. ptr += sizeof(data); std::cout << std::hex << data << " " << std::endl; } int main(int, char**) { unsigned char buffer[] = { 0x11, 0x11, 0x11, 0x11, 0x22, 0x22, 0x22, 0x22, }; /* const */ unsigned char* ptr = buffer; PrintInt(ptr); // error C2664: ... PrintInt(ptr); // error C2664: ... return 0; } When I run this code (in VS2008) I get this: error C2664: 'PrintInt' : cannot convert parameter 1 from 'unsigned char *' to 'const unsigned char *&'. If I uncomment the "const" comment it works fine. However shouldn't pointer implicitly convert into const pointer and then reference be taken? Am I wrong in expecting this to work? Thanks!

  • How do I get a reference to a rootViewController to a sub-view?

    - by Andy
    An answer posted for one of my previous questions brings up another question; I am calling a new view controller, "RuleBuilder," from my rootViewController. The rootViewController holds a reference to a contacts array. How do I get a reference to that array into the RuleBuilder? I tried adding UITableViewController *rootViewController; ... @property (nonatomic, retain) UITableViewController *rootViewController; to RuleBuilder.h, and then @synthesize rootViewController; in RuleBuilder.m. When I instantiate and push the RuleBuilder from within rootViewController, I do this: ruleBuilder.rootViewController = self; But when I try this [rootViewController.contacts addObject:newContact]; from within RuleBuilder, I get a compiler error to the effect of "request for 'contacts' in something not a struct" (or very similar; I haven't implemented this exact snippet of code, but I tried an identical approach not an hour ago for a couple of different references that I never was able to get working). Thanks, again, for your help.

  • Improving the performance of XSL

    - by Rachel
    In the below XSL for the variable "insert-data", I have an input param with the structure, <insert-data> <data compareIndex="4" nodeName="d1e1"> <a/> </data> <data compareIndex="5" nodeName="d1e1"> <b/> </data> <data compareIndex="7" nodeName="d1e2"> <a/> </data> <data compareIndex="9" nodeName="d1e2"> <b/> </data> </insert-data> where "nodeName" is the id of a node and "compareIndex" is the position of the text content relative to the node having id "$nodeName". I am using the below XSL to select all the text nodes(generate-id) that satisfy the above condition and construct a data xml. The below implementation works perfectly but the time taken for the execution is in min. Is there a better way of implementing or is there any in-efficient operation being used. From my observation the code where the preceding text length is calculated consumes the major time. Please share your thoughts to improve the performance of the XSL. I am using Java SAXON XSL transformer. <xsl:variable name="insert-data" as="element()*"> <xsl:for-each select="$insert-file/insert-data/data"> <xsl:sort select="xsd:integer(@index)"/> <xsl:variable name="compareIndex" select="xsd:integer(@compareIndex)" /> <xsl:variable name="nodeName" select="@nodeName" /> <xsl:variable name="nodeContent" as="node()"> <xsl:copy-of select="node()"/> </xsl:variable> <xsl:for-each select="$main-root/*//text()[ancestor::*[@id = $nodeName]]"> <xsl:variable name="preTextLength" as="xsd:integer" select="sum((preceding::text())[. ancestor::*[@id = $nodeName]]/string-length(.))" /> <xsl:variable name="currentTextLength" as="xsd:integer" select="string-length(.)" /> <xsl:variable name="sum" select="$preTextLength + $currentTextLength" as="xsd:integer"></xsl:variable> <xsl:variable name="split-index" select="$compareIndex - $preTextLength" as="xsd:integer"></xsl:variable> <xsl:if test="($sum ge $compareIndex) and ($compareIndex gt $preTextLength)"> <data split-index="{$split-index}" text-id="{generate-id(.)}"> <xsl:copy-of select="$nodeContent"/> </data> </xsl:if> </xsl:for-each> </xsl:for-each> </xsl:variable>
