• In Flash Actionscript 3.0 how do I create smooth keyboard controls for player movement?

  - by Reid

  I am a beginner in Flash Actionscript 3.0 programming. I am trying to create smooth keyboard controls for player movement in a game. I'm currently using addEventListener(KeyboardEvent.KEY_DOWN) listening for a keyboard key press and then within the handler function moving a graphic by adding a number to its .x or .y property. This creates a slow, sluggish jerk at the beginning. I know there's a smoother, more responsive way to do this but have no idea where to begin. Any help would be appreciated!

• How can I efficiently retrieve a large number of database settings as PHP variables?

  - by Steven

  Currently all of my script's settings are located in a PHP file which I 'include'. I'm in the process of moving these settings (about 100) to a database table called 'settings'. However I'm struggling to find an efficient way of retrieving all of them into the file. The settings table has 3 columns: ID (autoincrements) name value Two example rows might be: 1 admin_user john 2 admin_email_address [email protected] The only way I can think of retrieving each setting is like this: $result = mysql_query("SELECT value FROM settings WHERE name = 'admin_user'"); $row = mysql_fetch_array($result); $admin_user = $row['value']; $result = mysql_query("SELECT value FROM settings WHERE name = 'admin_email_address'"); $row = mysql_fetch_array($result); $admin_email_address = $row['value']; etc etc Doing it this way will take up a lot of code and will likely be slow. Is there a better way? Thanks.

• OpenGL gluLookAt issues

  - by Chris D

  I am trying to switch my space invaders game to a first person view, i.e. a view of the world from the ship. I am getting a bit confused about what point I should be looking at. I am currently using these parameters in gluLookAt: GL11.glMatrixMode(GL11.GL_MODELVIEW); GL11.glLoadIdentity(); GLU.gluLookAt(ship3dPos.x, ship3dPos.y, ship3dPos.z,400.0f, 600.0f,-50.0f, 0.0f, 1.0f,-0.0f); Where ship3dPos is a Vector3f. I'm not sure what I'm supposed to set parameters 4,5 and 6 to, to get a view of the whole world(window is 800/600). I want to have a view of say 100.0 wide from the ships perspective, with this view moving along the x-axis as the player moves the ship. Thanks

• Delete/move a UITableView row that's attached to a web service.

  - by Kevin L.

  Deleting or moving rows for a UITableView that is backed with local data (e.g., NSArray) is easy and instantaneous: Remove the value from the array. Call deleteRowsAtIndexPaths:withRowAnimation:. Profit! But my table view communicates with a web service, which means once the "Delete" button on that row gets tapped, I have to forward a request on to the server (via ASIHTTPRequest, of course), get the response, and then tell the table view to run its little delete-row animation, all with a few seconds of latency in between. From a high-level, what's the best way to do that? Throw some callback selector into ASIHTTPRequest's userInfo dictionary? KVO? Bonus points for some nice UI touch, like some kind of spinner on the soon-to-be-deleted cell.

• mootools: $ not defined

  - by eaigner

  I've strange error i don't understand. I'm just moving my code from jQuery over to Mootools because it's much cleaner than the jQuery mess. Now when i use the $$('div.canvas') in mootools i get the correct element. When i try $(document).getElement('div.canvas') it tells me that $ is not defined. How can $$ and all helper functions like $lambda etc. be defined but not $? Has something changed there from 1.1 to 1.2 and the docs are not updated yet?

• Design best practice - best way to handle user selection

  - by user1457227

  I'm an experienced developer (WPF) moving over to Android development. My question: an app I am developing allows the user to browse their local storage (such as SDCARD) and select a file. Now, should I simply create a new Activity (after the user has made a selection) to handle what I want to have the app do with that chosen file, -or- is the better approach to pass the path/name of the selected file back to the main Activity and let IT launch the next Activity? In other words, is the better practice to have the main Activity launch other (support) activities, or is it perfectly ok and normal to have one activity chain to another and on and on? Thanks!

• Maven + Tomcat acceleration

  - by Bar

  I am writing a web application with Maven in the Eclipse IDE, and use Tomcat servlet container. So, I run Maven like this: mvn clean compile. It is reasonable that after this oepration I must re-run Tomcat so it can reinitialize the context (Sysdeo Tomcat launcher helps a lot). The problem is Maven execution and subsequebt Tomcat re-running takes noticable amount of time (like 10+ seconds for Maven and 20+ sec. for Tomcat, because of logging, Hibernate mappings, etc.) every time I do it. Is there any automated and more faster solution for these two operatioins? As I see it, a way better solution can be moving re-compiled classes only to the target dir.

• How to inplement a nightly process in .NET?

  - by Abe Miessler

  I have a set of tasks that I would like to execute every night. These tasks include querying a database, moving and renaming some images and lastly updating a database table. My first thought had been to create a SQL Server job and use xp_cmdshell to move the files but after a bit of research i decided against it. My question now is what is the best way to implement this as a .NET application? Should I create a Windows service? A console application that is scheduled to run once per night? Some other cool way that I don't even know about?

• Sequencing ajax requests

  - by Scott Evernden

  I find I sometimes need to iterate some collection and make an ajax call for each element. I want each call to return before moving to the next element so that I don't blast the server with requests - which often leads to other issues. And I don't want to set async to false and freeze the browser. Usually this involves setting up some kind of iterator context that i step thru upon each success callback. I think there must be a cleaner simpler way? Does anyone have a clever design pattern for how to neatly work thru a collection making ajax calls for each item?

• Controlling new features in Spring/Apache tomcat

  - by HeretoLearn

  Is there a good way to manage roll out of new software in Spring/Tomcat configuration. The problem I am trying to address is being able to rollback newly deployed software provided there are no hard dependencies on other moving pieces. For example changed the guts of an algorithm and now want to deploy the new software with the new change off by default and then turning it on on one of the web servers. An obvious way is to build a session object which has a map of key-value pairs(property,bool) which is populated from a db on a session startup and then the value is persisted for that session. This is so that if the value is reverted back existing sessions which started with the original value retain the original value and giving application consistency. Is there a more obvious inbuilt mechanism to do this?

• iPhone Accelerometer Values

  - by Mike

  My question is about the iPhone accelerometer. Does the accelerometer measure acceleration or movement of the iPhone? What I mean is if I hold the iPhone and go from 0mph to 60mph, I would expect the measure of acceleration to increase in value from 0 to 60, but once I reach 60, I expect the value to return to 0 since I am "no longer accelerating" but am moving at a constant speed. Now if the accelerometer measure motion, I would expect it to register 0 to 60 and continue to provide a change in value as I move forward at 60mph. Sorry, I looked at a few books, programmed some code (values seemed to small to give a recognizable result over short distances or speeds), and a lot of web searches, and I am trying to get an answer to this question. Thanx!

• Use C function in C++ program; "multiply-defined" error

  - by eom

  I am trying to use this code for the Porter stemming algorithm in a C++ program I've already written. I followed the instructions near the end of the file for using the code as a separate module. I created a file, stem.c, that ends after the definition and has extern int stem(char * p, int i, int j) ... It worked fine in Xcode but it does not work for me on Unix with gcc 4.1.1--strange because usually I have no problem moving between the two. I get the error ld: fatal: symbol `stem(char*, int, int)' is multiply-defined: (file /var/tmp//ccrWWlnb.o type=FUNC; file /var/tmp//cc6rUXka.o type=FUNC); ld: fatal: File processing errors. No output written to cluster I've looked online and it seems like there are many things I could have wrong, but I'm not sure what combination of a header file, extern "C", etc. would work.

• R.java doesn't exist...but it does! Problem started after installing ADT 10.0.0

  - by TenFour04

  I get this error when I try to clean a project: ERROR: Unable to open class file ....R.java: No such file or directory So I can't build my projects any more. But R.java is there in the gen folder and looks fine when I open it. This happens to every one of my projects. I tried completely deleting the Eclipse folder and reinstalling it (Helios on Windows) and Android ADT. No luck. I have also tried moving my workspace to a different drive. No luck. I made sure all folders in my workspace are not read only. This worked the first time, but immediately the error came back when I cleaned my project. This all started right after installing ADT 10.0. I am wondering if it somehow is building R.java as a read-only file. EDIT: Is deleting the eclipse directory sufficient to reset all of its configuration?

• Inserting a number into a sorted array!

  - by Jay

  I would like to write a piece of code for inserting a number into a sorted array at the appropriate position (i.e. the array should still remain sorted after insertion) My data structure doesn't allow duplicates. I am planning to do something like this: 1. Find the right index where I should be putting this element using binary search 2. Create space for this element, by moving all the elements from that index down. 3. Put this element there. Is there any other better way?

• Bundling images with Blackberry

  - by Casebash

  How do I get bundled images with the BlackBerry Eclipse Plugin 1.1 Beta? I copied an image into "res/background.jpg" and tried to load it using Bitmap.getBitmapResource on background.jpg. Unfortunately, the image wasn't found (Illegal argument exception). I tried moving my image file into the src folder as per the advice here, but that didn't work either. I have opened up the .jar file and the background image is present at the root of the .jar file. The option to convert image files to .png isn't selected either. Links Could not find sample Library Reference

• Multiple System.Web.Extensions assembly in same project?

  - by CL4NCY

  Hi, I'm having trouble moving a website from one server to another. It seems to be a problem loading multiple versions of System.Web.Extensions. The code uses version 3.5 in most places but a third party control appears to be needing version 1.0.6. I didn't think this was possible but it appears to be working in it's current situation. Is there a way I can use the GAC version of System.Web.Extensions for the site but import a dll of version 1.0.6 just for these controls?

• Correct folder structure for sites

  - by Francesca

  I've just started tidying up the server for a particular site and am running into some trouble when moving files. I originally had style.css in my main folder, and another folder called images, so paths in the .css went images/myimage.png Now I have moved style.css into another folder called css. So the image links in the CSS no longer work, as it's looking for the folder images from it's own CSS folder. I changed the file path to /images/myimage.png as I thought this would make it climb up a level and then look for the images folder, but this doesn't seem to work. I'm interested to see what solutions people have and also any suggestions on how people organise their folders for a particular site. Thanks!

• What would be my best MySQL Synchronization method?

  - by Kerry

  We're moving a social media service to be on separate data centers with global load balancing, as our other hosting provider's entire data center went down. Twice. This means that both websites need to be synchronized in some sense -- I'm less worried about the code of the pages, that's easy enough to sync, but they need to have the same database data. From my research on SO, it seems MySQL Replication is a good option, but the MySQL manual, for scaling out, says that its best when there are far more reads then there are writes/updates: http://dev.mysql.com/doc/refman/5.0/en/replication-solutions-scaleout.html In our case, it's about equal. We're getting around 200-300 thousand requests a day right now, and we can grow rapidly. Every request is both a read and write request. What would be the best method or tool to handle this?

• ActionScript Local X And Y Coordinates Of Display Object?

  - by TheDarkIn1978

  i'm trying to trace the x and y coordinates from within a sprite. i've added a rectangle to the stage: var rect:Rectangle = new Rectangle(10, 10, 200, 200); addChild(rect); adding a Mouse_Move event to the rect, i can trace mouseX and mouseY to receive the coordinates of the stage while moving over the rect, but how do i get the local x and y coordinates? so if i mouse over the very top left of the rect sprite, the mouseX and mouseY return 10 as the global coordinates, but how do i make it return 0 and the local coordinates of the sprite? i assumed localX and localY was what i was looking for, but this doesn't work: function mouseOverTraceCoords(evt:MouseEvent):void { trace(mouseX, mouseY, evt.localX, evt.localY); }

• Show a Copying-files dialog/form while manually copying files in C#?

  - by Dinoo

  I am manually copying some folders and files through C#, and I want to show the user that something is actually going on. Currently, the program looks as if its frozen, but it is actually copying files. I would think there is already a built-in dialog or form that shows the process, similar to copying/moving files in windows explorer. Is there anything like that available, or will I have to create everything from scratch? Also, would this be the best method to show the user that something is actively going on? Thanks for the help!

• We failed trying database per custom installation. Plan to recover?

  - by Fedyashev Nikita

  There is a web application which is in production mode for 3 years or so by now. Historically, because of different reasons there was made a decision to use database-per customer installation. Now we came across the fact that now deployments are very slow. Should we ever consider moving all the databases back to single one to reduce environment complexity? Or is it too risky idea? The problem I see now is that it's very hard to merge these databases with saving referential integrity(primary keys of different database' tables can not be obviously differentiated). Databases are not that much big, so we don't have much benefits of reduced load by having multiple databases.

• 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

• Build multiple sources into multiple targets in a directory

  - by Taschetto

  folks. I'm learning about GNU-Make and I have the following project structure: ~/projects /sysCalls ex1.c ex2.c ex3.c ex4.c ex5.c ex6.c ex7.c Each .c source is very simple, has its own main function and must be built into a corresponding binary (preferably named after its source). But I want to build into a bin directory (added to my .gitignore file). My current Makefile is: CC := gcc CFLAGS := -Wall -g SRC := $(wildcard *.c) TARGET := $(SRC:.c=) all: bin $(TARGET) mv $(TARGET) bin/ bin: mkdir bin clean: rm -fr bin/ It works as expected, but always builds every source. And I don't like moving everything to bin "manually". Any tips or ideas on how this Makefile could be improved?

• Best way to use Cradle with Express.js (CouchDB, Node.js)

  - by Costa

  I'm building my website ( http://tedxgramercy.jit.su ) with express.js and so far I've been using the http.request method in node to access couch, and that's been cool. I've learned lots about how http, couch, and node work, which is awesome. Anyways, I'm thinking of moving over to cradle now (Let me know if you have a strong opinion about this) and I'd like to know the "right" way to set this up. Should I... require() cradle and make a new connection to my db in each separate route? create my database connection once, and then just pass that connection by require()ing the connection in each route? (if so, how do I do that?) Thanks!!!
