• How to play a set of jpeg files as a movie?

  - by RJ

  I have a set of jpeg images where eacg image has an associated description. e.g. im1.jpg - suspect enters bank im7.jpg - suspect hands teller a note imj41.jpg - teller gives suspect a bag ... ... It's trivial to view these images individually and see the description but how do I play this as a movie? I need to play the images and when I encounter one with a description, display the description in a status pane. Do I need to convert the images into a movie, if so how? How do I get the player to notify me when the description frame is encountered? I'm using Windows. language doesn't matter, I just need the concept right now.

• How can you prevent a window being captured by Print-Screen?

  - by John

  I noticed a few times than when I print-screen while Media Player is running, the content is replaced with a grey rectangle. I've no idea if it's deliberate due to DRM, or some technical issue, but it struck me that being able to deliberately block screen-capture might be a useful feature in some scenarios. Is there some specific message each HWND gets for print-screen - does Windows do a special repaint or simply dump buffers to the clipboard? I guess I'd prefer to focus this on Win32 specifically, but as long as it's Windows-related then fine.

• MonoTouch- 'curated' bindings?

  - by Glinkot

  I'm just converting a video player sample to MT and came to this part: self.view.layer.sublayerTransform = CATransform3DMakePerspective(1000); In Monotouch, I've started with: this.View.Layer.SublayerTransform(CATransform3D.... But no perspective option is available. There is a 'scale' and 'rotate' one - does this mean this functionality is unavailable in MT? Or that I need to start creating my own bindings even though this one has been processed by the binding creation tool Xamarin uses? If anyone could advise how I would apply that transform I'd appreciate it. Cheers

• Distributing players to tables

  - by IVlad

  Consider N = 4k players, k tables and a number of clans such that each member can belong to one clan. A clan can contain at most k players. We want to organize 3 rounds of a game such that, for each table that seats exactly 4 players, no 2 players sitting there are part of the same clan, and, for the later rounds, no 2 players sitting there have sat at the same table before. All players play all rounds. How can we do this efficiently if N can be about ~80 large? I thought of this: for each table T: repeat until 4 players have been seated at T: pick a random player X that is not currently seated anywhere if X has not sat at the same table as anyone currently at T AND X is not from the same clan as anyone currently at T seat X at T break I am not sure if this will always finish or if it can get stuck even if there is a valid assignment. Even if this works, is there a better way to do it?

• Game Objects Talking To Each Other

  - by PhilCK

  What is a good way of dealing with objects and having them talk to each other? Up until now all my games hobby/student have been small so this problem was generally solved in a rather ugly way, which lead to tight integration and circular dependencies. Which was fine for the size of projects I was doing. However my projects have been getting bigger in size and complexity and now I want to start re-using code, and making my head a simpler place. The main problem I have is generally along the lines of Player needs to know about the Map and so does the Enemy, this has usually descended into setting lots of pointers and having lots of dependencies, and this becomes a mess quickly. I have thought along the lines of a message style system. but I cant really see how this reduces the dependencies, as I would still be sending the pointers everywhere. Thanks. PS: I guess this has been discussed before, but I don't know what its called just the need I have.

• Writing an AI for a turn-based board game

  - by Cyril

  Hi, i'm currently programming a board game (8x8) in which I need to develop an AI. I have read a lot of articles about AI in board games, minmax with or without alphabeta pruning, but I don't really know how to implements this, I don't know where to start... About my game, this is a turn-based game, each player has pieces on the board, they have to pick one and choose in moving this piece (1 or 2 cells max) or clone the piece (1 cell max). At the moment, I have a really stupid AI which choose a random piece then choose a random move to play... Could you please give me some clues, on how to implement this functionality ? Best regards

• Keeping some files private

  - by user490895

  Hi, I was trying to create a directory of private files that could only be accessed when a user logs in. To do this, I used a folder outside the web directory, and then php to access it, if allowed. Here's an example: function display_movie($file){ printf("<video id='movie' width='960' height='416' controls='controls' onerror='fix()'> <source src='movie.php?file=%s' type='video/ogg; codecs=\"theora, vorbis\"'> </video>", rawurlencode($file)); } This works great for images, but breaks the media player. Also, I've only tested this locally on a Linux machine. Any ideas? Thanks.

• HTML5 Local Storage of audio element source - is it possible?

  - by andrewdotcom

  Hi stackoverflow experts I've been experimenting with the audio and local storage features of html5 of late and have run into something that has me stumped. I'd like to be able to cache or store the source of the audio element locally to enable speedier and offline playback. The problem is I can't see how this is possible with the current implementation. I have tried the following using webkit: Creating a manifest file to set up local caching but the audio file appears not to be a cacheable item maybe due to the way it is stream or something I have also attempted to use javascript to put an audio object into local storage but the size of the mp3 makes this impossible due to memory issues (i think). I have tried to use the data uri and base64 to use the html as a audio transport that can be cached but again the filesize makes this prohibitive. Also the audio element does not seem to like this in webkit (works fine in mozilla) I have tried several methods of putting the data into the local database store. Again suffering the same issues as the other cases. I'd love to hear any other ideas anyone may have as to how I could achieve my goal of offline playback using caching/local storage in webkit.

• Possibility of initiating playback of flash video on headless server through the terminal

  - by brendan morrison

  Hey so I have a website which has video's gathered from places around the web, primarily youtube but a few other's as well. Now I am wondering if there is some way to check link's to make sure they are still available through a unix shell. (My idea is to run a cron to check videos are still available and if not delete them.) I am aware i could use user to do this but it always bothered me and was wondering if there is somehow to check the playback of a flash video though the terminal . Any insight into this would be awesome as I haven't found much on the web. Also note ideally the tech. will work on all video type's including html5. update So it's occured to me that through the you tube api, I could check the status of the video's coming from youtube (which is a start). But I would love to know if there's something else that is not player specific but rather just calls the video to play similar to how a user would.

• How to do something when AVQueuePlayer finishes the last playeritem

  - by user1634529

  I've got an AVQueuePlayer which I'm creating from an array of 4 AVPlayerItems, and it all plays fine. I want to do something when the last item in the queue finishes playing, I've looked a load of answers on here and this is the one that looks most promising for what I want: The best way to execute code AFTER a sound has finished playing In my button handler i have this code: static const NSString *ItemStatusContext; [thePlayerItemA addObserver:self forKeyPath:@"status" options:0 context:&ItemStatusContext]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerItemDidReachEnd) name:AVPlayerItemDidPlayToEndTimeNotification object:thePlayerItemA]; theQueuePlayer = [AVQueuePlayer playerWithPlayerItem:thePlayerItemA]; [theQueuePlayer play]; and then I have a function to handle playerItemDidReachEnd: - (void)playerItemDidReachEnd:(NSNotification *)notification { // Do stuff here NSLog(@"IT REACHED THE END"); } But when I run this I get an Internal Inconsistency Exception: An -observeValueForKeyPath:ofObject:change:context: message was received but not handled. Key path: status Observed object: <AVPlayerItem: 0x735a130, asset = <AVURLAsset: 0x73559c0, URL = file://localhost/Users/mike/Library/Application%20Support/iPhone%20Simulator/5.0/Applications/A0DBEC13-2DA6-4887-B29D-B43A78E173B8/Phonics%2001.app/yes.mp3>> Change: { kind = 1; } What am I doing wrong?

• C# - opening process and changing window position

  - by bartq

  I want to open from c# an application (standalone flashplayer) and set it position to (0,0) on the screen. How can I do this? So far I've managed to open flashplayer: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; namespace swflauncher { class Program { static void Main(string[] args) { Process flash = new Process(); flash.StartInfo.WindowStyle = ProcessWindowStyle.Normal; flash.StartInfo.FileName = "D:\\development\\flex4\\runtimes\\player\\10\\win\\FlashPlayer.exe"; flash.Start(); } } }

• Drawing problem does ShowWindow(hWnd, SW_HIDE) automatically invalidate rectangles?

  - by wk1989

  Hello, I'm running into a problem where, I have a Window that contains a child window. The child window contains another child window where a video is playing using Windows Media Player. Whenever I do call ShowWindow (hWnd, SW_HIDE) on the parent Window and paint over the entire surface, the region occupied by the grand-child window (where the video was playing) is not overridden. I used spy++ and found that that region which was not overridden was set to hidden BEFORE the repaint occurs. I monitored the hwnd of the grand-child window and it did not seem to receive any WM_EraseBKGND or WM_NCPAINT messages. Does this mean the area it occupied had not been invalidated and therefore could not be drawn over? I'm new to winforms. Thanks!

• Loading multiple embedded flash apps onto an HTML page- problem with ordering

  - by shudson250

  We need to load an embedded version of a site written in Flash, and not originally designed to load multiple instances of itself, on a HTML page. The specific issue is how to get them to load in order when embedded, given that they are all being opened by the same instance of the flash player. It's a complicated mapping application, and at the moment, the maps and data get intermixed as the session variables are overwritten by another instance starting to load before the previous one has finished. We need a way to have them load sequentially, one finishing before another starts to load. The most we can specify in the URL is an &order=1 or similar. We have PHP and SQL on the backend. Edit: The embedded versions are being loaded in an iFrame of a parent site. One php file loads one swf, as many times as the parent site desires.

• JButtons don't imediatly change on mouse event

  - by out_sider

  I'm using the java swing library to develop a board game called DAO. The problem is that after the human player makes its move, by clicking on the JButton with the piece image that he wants to play, I call the computer AI routine but inside the mouse event function. By doing this only when the function returns, the computer ends its turn, do the JButtons refresh their Images (setIcon comes in). I'd like to know how can I force the JButtons to change their image at the moment they are clicked and not only when the mouse event function ends (as I need to handle data inside it). I've tried all of this myButtons[i][j].setIcon(xIcon); myButtons[i][j].revalidate(); myButtons[i][j].repaint(); myButtons[i][j].validate(); None worked. Thx in advance

• How online-game clients are able to exchange data through internet so fast?

  - by Kirzilla

  Hello, Let's imagine really simple game... We have a labirinth and two players trying to find out exit in real time through internet. On every move game client should send player's coordinates to server and accept current coordinates of another client. How is it possible to make this exchange so fast (as all modern games do). Ok, we can use memcache or similar technology to reduce data mining operations on server side. We can also use fastest webserver etc., but we still will have problems with timings. So, the questions are... What protocol game clients are usually using for exchanging information with server? What server technologies are coming to solve this problem? What algorithms are applied for fighting with delays during game etc. PS: Sorry for my English and I hope that my question is clear. Thank you.

• How to check for a file's authenticity ?

  - by Ale_x

  Let's say I write a game application. I want the level of the player to be stored in an external file. How can I prevent a hacker from writing and modifying the file to put another level ? I want the file to be modified by my application only. I can sign the file's content with a key, but then this key will be stored in the application, therefore it would be possible for a hacker to decompile the binary and find the key. Is there any way to do this ?

• ActionScript arrays being automatically set to other values

  - by nababa

  I am making a flash game, in each round, the player will chose either True or False. The decision of each round will be stored in an array. That is, it looks like {true, false, true, false}.. When the user clicks the "Debrief“ button, the eventlistener will be called and the game will go to the debriefing part. It will read the array mentioned before. However, the array values are all "false". I am very sure that the array has not being touched in between. So, any ideas about why the array is set to false mysteriously?

• How to have a run in an Service?

  - by user1497664

  I have implemented an service that runs in a seperate process. This service contains a separate thread where i have a socket connection. This thread has a run() where it is continuously sending data to the port. My problem is after triggering the run() in the thread i don't get any contact with it anymore, i can see in the program that have open the socket that it consciously sends the data but the idea was that i while it is running i could change data that it sends for an example time. here is my run in the external thread: public void run() { if(run) { // Team and player names message is sent when entering in a game setBaseMessage(); SendMessageToCOMPort(base_message + CalculateCRC(base_message)); sleep(); // waits for 100 ms } } Anyone have any idea what might be wrong ?

• Embedded YouTube video slows down page load

  - by Tom S

  Hi, total newbie here - trying to figure out how to make a page load faster with 1 embedded YouTube video on it - a very modest page takes an extra 5 seconds to completely load with the YouTube player showing up. I'd either like the page to load first or to only load the video when user clicks on it - don't know how to do that.. Here is the YouTube video embed code: <object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/kfZIIKVfJ1w&hl=en_US&fs=1&rel=0&hd=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/kfZIIKVfJ1w&hl=en_US&fs=1&rel=0&hd=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object> Thanks for your help!

• Way of knowing who called a singleton - objective C

  Hello, I am designing a game with several levels. I have a CCLayer defined as a singleton (called MasterScene) where I handle the pause page, transition page, player's score banner,... all the things common to all levels. So in each level, when the user pushes the pause button, a call is made to the singleton to display the CClayer corresponding to the pause page. My problem is that I want to know who called the singleton (which level) t. Is there a way of doing that ? Thanks

• port an iOS (iPhone) app to mac?

  - by William Jockusch

  Is there a preferred way to go about this? The app in question is not too large . . . single-player game that I wrote over the course of a couple of months. EDIT: I should add that I have no experience with mac development . . . outside of what comes naturally with being an iOS developer. EDIT: Classes heavily used in the game: subclasses of NSObject, UIView, and UIViewController. I don't know much about NSView, but I'm pretty sure all the UIView stuff will work in that class. Also some use of UITableViewController. I do also have Game Center, but I can leave that part out for now. There is no multi-touch.

• Dealing with large directories in a checkout

  - by Eric

  I am trying to come up with a version control process for a web app that I work on. Currently, my major stumbling blocks are two directories that are huge (both over 4GB). Only a few people need to work on things within the huge directories; most people don't even need to see what's in them. Our directory structure looks something like: / --file.aspx --anotherFile.aspx --/coolThings ----coolThing.aspx --/bigFolder ----someHugeMovie.mov ----someHugeSound.mp3 --/anotherBigFolder ----... I'm sure you get the picture. It's hard to justify a checkout that has to pull down 8GB of data that's likely useless to a developer. I know, it's only once, but even once could be really frustrating for someone (and will make it harder for me to convince everyone to use source control). (Plus, clean checkouts will be painfully slow.) These folders do have to be available in the web application. What can I do? I've thought about separate repositories for the big folders. That way, you only download if you need it; but then how do I manage checking these out onto our development server? I've also thought about not trying to version control those folders: just update them directly on the web server... but I am not enamored of this idea. Is there some magic way to simply exclude directories from a checkout that I haven't found? (Pretty sure there is not.) Of course, there's always the option to just give up, bite the bullet, and accept downloading 8 useless GB. What say you? Have you encountered this problem before? How did you solve it?
