• How to authenticate multiple entry points in a facebook app?

  - by Simon_Weaver

  I am using an IFrame application with XFBML and the new Javascript API. I'd like to have a facebook application with multiple entry points. These will most likely represent different links coming from a fan page tab. I can do this quite easily if the pages don't require authentication - for instance I can create several pages under the app and if a new user comes I can send them to any page: http://apps.facebook.com/myapp/offers http://apps.facebook.com/myapp/game http://apps.facebook.com/myapp/products The problem is that if I need to have authentication then once the user is authenticated they get redirected to my default post-authorization url. Is there a way for a user that comes to /game to stay on /game after they are authenticated without redirecting. I thought I could do it with the AJAX login form - but I cannot find out how to do that in a Facebook IFrame application. I think the example using requirelogin only works for FBML. <a href="http://apps.facebook.com/mysmiley" requirelogin=1> Welcome to my app</a>. Is there a way to accomplish this with Facebook APIs - or will I have to do some kind of clever cookie handling?

• Problem of Sprites and labels are displayed by white boxes.

  - by srikanth rongali

  I am writing a game in cocos2d. I am using a function restartDirector in AppDelegate class. -(void)restartDirector{ [[CCDirector sharedDirector] end]; [[CCDirector sharedDirector] release]; if( ! [CCDirector setDirectorType:CCDirectorTypeDisplayLink] ) [CCDirector setDirectorType:CCDirectorTypeDefault]; [[CCDirector sharedDirector] setPixelFormat:kPixelFormatRGBA8888]; [CCTexture2D setDefaultAlphaPixelFormat:kTexture2DPixelFormat_RGBA8888]; [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] setDisplayFPS:YES]; [[CCDirector sharedDirector] setDeviceOrientation:CCDeviceOrientationLandscapeLeft]; [[CCDirector sharedDirector] attachInView:window]; } This function I called in one of the game Scene . -(void)PracticeMethod:(id)sender { [MY_DELEGATE restartDirector]; CCScene *endPageScene = [CCScene node]; CCLayer *endPageLayer = [DummyScene node]; [endPageScene addChild:endPageLayer]; [[CCDirector sharedDirector] runWithScene:endPageScene]; // [[CCDirector sharedDirector] replaceScene:endPageScene]; } When used the replaceScene, there is no problem in game but the memory of abject allocation is high(I checked in leaks tool). So I used runWithScene. But , while using these when the scene DummyScene is loaded the sprites, labels in it are displayed by white boxes. I cannot see the sprites and labels. If I am using replaceScene everything thing is working fine but the memory allocation is high. this is my problem. Thank you.

• How can I handle unread push notifications in iOS?

  - by Bartserk

  I have a iOS 5.1 application that registers to the APNS service to receive notifications. The register is successful and I receive the notifications correctly. The problem comes when I try to handle the notifications. Once the application is running, the method didReceiveRemoteNotification in the AppDelegate is called correctly and so the notification is handled as intended. This, however, only happens when the application is running on the foreground. However, when the application is running on the background or is simply stopped, that method is not called. I've read that you should add some lines to the method didFinishLaunchingWithOptions method to obtain the notification from the userInfo dictionary, and handle it. This works just fine, but ONLY when the application is opened by clicking on the notification at the Notification Center. This means that if you open the application by clicking on its badge, or simply by changing context if you were running it on the background, the app never realises that a notification came in. Additionally, if more than one notification was received, we can only handle one of them at once by clicking on the Notification Center, which is a pain :-) Is there any way to read the pending notifications in the Notification Center? I know there is a way to flush them using the method cancelAllLocalNotifications but I haven't found a way to just read them. And I really need to handle all of them. I thought of implementing a communication protocol with the third-party notification server to retrieve the information again when the application comes to the foreground, but since the information is already in the operating system I would find it strange if it's impossible to access it somehow. So, does anybody know a way to do it? Thanks in advance.

• Accurately and securely measure the time spent viewing a web page

  - by balpha

  Suppose the following: You have a web page that presents a simple game to a user (e.g. a quiz, a puzzle, etc). The user solves the puzzle, submits the result, and you want to measure as precisely as possible how long they took to solve it. Assume it's quite simple, so we're talking seconds, not hours. Also assume JavaScript is required anyway, so there's no need to think of JS-disabled browsers. Finally, assume we don't want to use anything like Flash, Silverlight, or the like. I can think of several techniques: Simply take the time between the points when the data was sent from the server and when the submission arrives. Since this is exclusively server-side, there's no chance for cheating. However, issues like network latency and page rendering time might make this unfair for users with slow computers / browsers / internet connections. On the first request, just send the page without the actual game data. When everything is loaded so far, retrieve the game data through an AJAX call and populate it into the page. This is similar to 1., but reduces some of the caveats introduced through time spent on overhead. Have the time measured on the client side using JavaScript and submitted alongside with the solution. This would theoretically be the most accurate, but it introduces the possibility of cheating, because you're relying on client data. Use the request time headers of a "ready to play" AJAX call and the result submission request. Same caveat as 3., as it is still client data. A combination of server side and client side measuring with some kind of plausibility analysis. I can't think of a good way, but maybe you can. Thoughts? Other ideas?

• Licensing for the undecided

  - by Jasper

  I am creating a game in C++. Now I am not sure on how I will distribute it yet - though I am pretty sure that I won't be asking money for it. And I am looking into a licensing and I wondered if there is a license that is suited for the undecided like me. My current releases (which are really really early versions of the game, with far from full functionality) are executable only. However, I am actually thinking that I might release the source on an open source license. For now, I am the only contributor, so that would be no problem as I only need my own permission to move to a less restrictive license. However, when I allow other people to contribute, I would need all their permissions to do so (right?). So I was wondering if there is a license that let's me distribute the game executable only for now, but will let me switch to a less restrictive license if I want. Basically I need a license in which contributors give permission to switch to a less restrictive license up front. Does anybody know of license (or other construction) that would allow me to do so?

• Want to develop for Android. Have a few basic, non-FAQ questions

  - by Troy M

  Hi everyone, Recently myself and a small group of friends became interested in developing a game for a mobile platform. Originally we considered the iPhone but none of us use macs, so we decided Android would be a more realistic platform to use. Before we get started, I was hoping that I might find some answers to a couple questions so we don't waste our time if this project isn't feasible. Any help is appreciated! I can't seem to find out how many programming languages Android supports. Java is obvious, but what about C+? It seems that Android supports C and C++ through Eclipse, but is that it? (I'm not the programmer for the project which is why I'm asking this. He's comfortable in C+). Our game involves the use of two digital analog sticks (it's not a twin-stick shooter but it's a similar concept). It would seem that most Droid devices unfortunately don't use multi-touch though... Are there many devices out there right now which support this functionality and I'm just not seeing them, or should we possibly consider the development of a different game that would only use a single input? Assuming there's no snags following those first two questions, what would you consider the best screen resolution to develop in? It seems like there are a variety of resolutions out there right now and we can't decide which is the best to use. Again, any answers are appreciated!

• How do I switch out Views in a Cocoa application?

  - by David Garcia

  So I'm beginning to learn how to use Cocoa. I think I've pretty much got it but I'm hung up on creating and switching views. I'm rewriting a game I made a little bit ago for practice. All I want is one window (preferably not resizable) and I want to be able to switch out views for different screens in the game. First, I have the main menu (Start Game, High Scores, Exit). Then I need a window for each screen (Gameplay screen, Highscore screen). What I'm getting confused with is how to design this. I looked up NSViewController thinking it manages views but it doesn't. It only manages one view by loading it really. I don't understand why I'd need to use NSViewController then. Couldn't I just have a window class that contains multiple subclasses of NSView and load them like that? I'm not sure I understand the purpose of the ViewController. Does my Window Class really need to subclass NSWindowController? I was trying to follow the example of Apple's ViewController example and it has a window controller class that's a subclass of NSWindowController. I don't see what the purpose was of subclassing that. All NSWindowController seems to add is - initWithPath:(NSString *)newPath but I fail to see the use in that either when I can just edit the plist file to open the window on start up. Apple's example also has an NSView variable and an NSViewController variable. Don't you only need one variable to store the current view? Thanks in advance guys, I'm really confused as to how this works.

• How much is too much memory allocation in NDK?

  - by Maximus

  The NDK download page notes that, "Typical good candidates for the NDK are self-contained, CPU-intensive operations that don't allocate much memory, such as signal processing, physics simulation, and so on." I came from a C background and was excited to try to use the NDK to operate most of my OpenGL ES functions and any native functions related to physics, animation of vertices, etc... I'm finding that I'm relying quite a bit on Native code and wondering if I may be making some mistakes. I've had no trouble with testing at this point, but I'm curious if I may run into problems in the future. For example, I have game struct defined (somewhat like is seen in the San-Angeles example). I'm loading vertex information for objects dynamically (just what is needed for an active game area) so there's quite a bit of memory allocation happening for vertices, normals, texture coordinates, indices and texture graphic data... just to name the essentials. I'm quite careful about freeing what is allocated between game areas. Would I be safer setting some caps on array sizes or should I charge bravely forward as I'm going now?

• JPA - Real primary key generated ID for references

  - by Val

  I have ~10 classes, each of them, have composite key, consist of 2-4 values. 1 of the classes is a main one (let's call it "Center") and related to other as one-to-one or one-to-many. Thinking about correct way of describing this in JPA I think I need to describe all the primary keys using @Embedded / @PrimaryKey annotations. Question #1: My concern is - does it mean that on the database level I will have # of additional columns in each table referring to the "Center" equal to number of column in "Center" PK? If yes, is it possible to avoid it by using some artificial unique key for references? Could you please give an idea how real PK and the artificial one needs to be described in this case? Note: The reason why I would like to keep the real PK and not just use the unique id as PK is - my application have some data loading functionality from external data sources and sometimes they may return records which I already have in local database. If unique ID will be used as PK - for new records I won't be able to do data update, since the unique ID will not be available for just downloaded ones. At the same time it is normal case scenario for application and it just need to update of insert new records depends on if the real composite primary key matches. Question #2: All of the 10 classes have common field "date" which I described in an abstract class which each of them extends. The "date" itself is never a key, but it always a part of composite key for each class. Composite key is different for each class. To be able to use this field as a part of PK should I describe it in each class or is there any way to use it as is? I experimented with @Embedded and @PrimaryKey annotations and always got an error that eclipselink can't find field described in an abstract class. Thank you in advance! PS. I'm using latest version of eclipselink & H2 database.

• Geohashing - recursively find neighbors of neighbors

  - by itsme

  I am now looking for an elegant algorithm to recursively find neighbors of neighbors with the geohashing algorithm (http://www.geohash.org). Basically take a central geohash, and then get the first 'ring' of same-size hashes around it (8 elements), then, in the next step, get the next ring around the first etc. etc. Have you heard of an elegant way to do so? Brute force could be to take each neighbor and get their neighbors simply ignoring the massive overlap. Neighbors around one central geohash has been solved many times (here e.g. in Ruby: http://github.com/masuidrive/pr_geohash/blob/master/lib/pr_geohash.rb) Edit for clarification: Current solution, with passing in a center key and a direction, like this (with corresponding lookup-tables): def adjacent(geohash, dir) base, lastChr = geohash[0..-2], geohash[-1,1] type = (geohash.length % 2)==1 ? :odd : :even if BORDERS[dir][type].include?(lastChr) base = adjacent(base, dir) end base + BASE32[NEIGHBORS[dir][type].index(lastChr),1] end (extract from Yuichiro MASUI's lib) I say this approach will get ugly soon, because directions gets ugly once we are in ring two or three. The algorithm would ideally simply take two parameters, the center area and the distance from 0 being the center geohash only (["u0m"] and 1 being the first ring made of 8 geohashes of the same size around it (= [["u0t", "u0w"], ["u0q", "u0n"], ["u0j", "u0h"], ["u0k", "u0s"]]). two being the second ring with 16 areas around the first ring etc. Do you see any way to deduce the 'rings' from the bits in an elegant way?

• facebook Hacker cup: studious Student problem.

  - by smartmuki

  During the qualification round, the following question was asked: You've been given a list of words to study and memorize. Being a diligent student of language and the arts, you've decided to not study them at all and instead make up pointless games based on them. One game you've come up with is to see how you can concatenate the words to generate the lexicographically lowest possible string. Input As input for playing this game you will receive a text file containing an integer N, the number of word sets you need to play your game against. This will be followed by N word sets, each starting with an integer M, the number of words in the set, followed by M words. All tokens in the input will be separated by some whitespace and, aside from N and M, will consist entirely of lowercase letters. Output Your submission should contain the lexicographically shortest strings for each corresponding word set, one per line and in order. Constraints 1 <= N <= 100 1 <= M <= 9 1 <= all word lengths <= 10 Example input 5 6 facebook hacker cup for studious students 5 k duz q rc lvraw 5 mybea zdr yubx xe dyroiy 5 jibw ji jp bw jibw 5 uiuy hopji li j dcyi Example output cupfacebookforhackerstudentsstudious duzklvrawqrc dyroiymybeaxeyubxzdr bwjibwjibwjijp dcyihopjijliuiuy The program I wrote goes as: chomp($numberElements=<STDIN>); for(my $i=0; $i < $numberElements; $i++) { my $string; chomp ($string = <STDIN>); my @array=split(/\s+/,$string); my $number=shift @array; @sorted=sort @array; $sortedStr=join("",@sorted); push(@data,$sortedStr); } foreach (@data) { print "$_\n"; } The program gives the correct output for the given test cases but still facebook shows it to be incorrect.

• Need help extrapolating Java code

  - by Berlioz

  If anyone familiar with Rebecca Wirfs-Brock, she has a piece of Java code found in her book titled, Object Design: Roles, Responsibilities, and Collaborations. Here is the quote Applying Double Dispatch to a Specific Problem To implement the game Rock, Paper, Scissors we need to write code that determines whether one object “beats” another. The game has nine possible outcomes based on the three kinds of objects. The number of interactions is the cross product of the kinds of objects. Case or switch statements are often governed by the type of data that is being operated on. The object-oriented language equivalent is to base its actions on the class of some other object. In Java, it looks like this Here is the piece of Java code on page 16 ' import java.util.*; import java.lang.*; public class Rock { public static void main(String args[]) { } public static boolean beats(GameObject object) { if (object.getClass.getName().equals("Rock")) { result = false; } else if (object.getClass.getName().equals("Paper")) { result = false; } else if(object.getClass.getName().equals("Scissors")) { result = true; } return result; } }' ===This is not a very good solution. First, the receiver needs to know too much about the argument. Second, there is one of these nested conditional statements in each of the three classes. If new kinds of objects could be added to the game, each of the three classes would have to be modified. Can anyone share with me how to get this "less than optimal" piece of code to work in order to see it 'working'. She proceeds to demonstrate a better way, but I will spare you. Thanks

• Cocoa button won't display image

  - by A Mann

  Just started exploring Cocoa so pretty much a total noob. I've written a very simple game. Set it up in Interface Builder and got it working fine. It contains a number of buttons and I'm now trying to get the buttons to display images. To start with I'm trying to get an image displayed on just one of the buttons which is called tile0 . The image file (it's nothing but a green square at the moment, but I'm just trying to get that working before I attempt anything more exotic) is sitting in the same directory as the class file which controls the game. I have the following code sitting in my wakeFromNib method: NSString *myImageFileName = [[NSString alloc] init]; myImageFileName = @"greenImage.jpg"; NSImage *myImage = [[NSImage alloc] initByReferencingFile:myImageFileName]; [tile0 setImage: myImage]; Trouble is, the game runs fine, but the image isn't appearing on my button. Is there someone who could kindly tell me if I'm doing something obviously wrong? Many Thanks.

• How to set default view in OpenLayers, WITHOUT restricting bounds?

  - by Jenny

  Based on samples, I can see that you can set a default view in OpenLayers by saying something along the lines of: var bounds = new OpenLayers.Bounds(-125, 25, -65, 50); var map = new OpenLayers.Map('map', {restrictedExtent: bounds }); However, this also (as the name implies), restricts me to be able to ONLY navigate within these bounds. I can zoom out and see things outside of these bounds, but I can't then zoom back onto them, or scroll to them. I've tried not having any restrictedExtent (or making it the entire map), but then I can't get it to focus on the area I want. I tried using: map.setCenter(new OpenLayers.LonLat(0,0), 3); console.log(map.getCenter()); To set the zoom and the center...but it doesn't seem to do ANYTHING, other than set the variable "center" which I can then read from map.getCenter() (if I don't set it, it's null, if I do set it, I can see it...but the map itself stays fully extended and it's center doesn't seem to change at all...) The Map layer I am using is: OpenLayers.Layer.OSM.Mapnik with displayOutsideMaxExtent set to true... I'm really at a loss here. My goal is to have a default region of the world zoomed in to and in view (such as the United States), with the option of viewers being able to go outside the default to view things.

The code are as follows The protocol part is @protocol Protocol @required -(void) transition1:(id) sender; @end The function which is to be invoked in the game code is (void) transition1:(id) sender { [[Director sharedDirector] replaceScene: [ [Scene node] addChild: [Layer4 node] z:0] ]; } The code in the overlay view in MovieOverlayViewController.h import "Protocol.h" @interface MovieOverlayViewController : UIViewController { UIImageView *overlay; NSObject <Protocol> *transfer; } @end The code in the overlay view in MovieOverlayViewController.m @implementation MovieOverlayViewController (id)init { if ((self = [super init])) self.view = [[[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease]; return self; } -(void) viewWillAppear:(BOOL)animated { overlay = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"overlay.png"]] autorelease]; [self.view addSubview:overlay]; } (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint point = [touch locationInView:self.view]; NSLog(@"pointx: %f pointy:%f", point.x, point.y); if (CGRectContainsPoint(CGRectMake(1, 440, 106, 40), point)) { // the function is called here [transfer transition1: nil]; } else if (CGRectContainsPoint(CGRectMake(107, 440, 106, 40), point)) NSLog(@"tab 2 touched"); } (void)dealloc { [overlay release]; [super dealloc]; } @end

• How to get unique value in jquery?

  - by jquerier

  I am learning jquery. I have following chunk of code in a html file: <table width="100%"> <tr> <td align='center'> <div> <a id='get_this' href='#'> <input type='hidden' id='id' value='1'><img src='images/1.gif'></a> </div> </td> <td align='center'> <div> <a id='get_this' href='#'> <input type='hidden' id='id' value='2'><img src='images/2.gif'></a> </div> </td> <td align='center'> <div> <a id='get_this' href='#'> <input type='hidden' id='id' value='3'><img src='images/3.gif'></a> </div> </td> </tr> What I want to do is, when I click any of the image, I can get the value, so that I can display the information. For example, I click the id=1, then I will display information on id1 in somewhere else. I tried this: $("a#get_this").click(function(){ var id = $('input[type=hidden]#id').val(); window.alert("You have chosen the id: " + id); }); It always return id: 1 to me.

• Recover lost code from compiled apk

  - by AlexRamallo

  I have an issue here..and its making me really nervous. I was working on this game, and it was going great, so I took a copy of it on my laptop to work do some work while away from my computer. long story short, hard-drive failure + poor back ups led to me losing a very important class. Is there a way to decompile the apk to retrieve the bit of code that was lost? It isn't overly complicated or sophisticated, its just that its impossible to re-write it without reading every. single. line. of. code. in the entire application since it initializes a LOT of classes and loads a bunch of stuff in a specific way. With a quick google search I was able to find apktool, which decompiles it into a bunch of .smali files, which I don't think were designed for human reading. All I need to recover is one very big method in the class. I found the smali file that contains it and I think I found the line where it starts. something like .method public declared-synchronized load(Lcom/X/X/game/X;)I Anyone help would be appreciated since I would have to scrap the entire game without this method.
