  • Particle Effect Completion

    - by Siddharth
    In my game I use particle effect for various purposes. In that I detect the completion of the particle effect. Basically I want to do something after completion of the particle effect. But the problem is that I didn't able to find the particle effect completion. So any community member please help me. EDIT : I was creating particle effect using following code pointParticleEmtitter = new PointParticleEmitter(pX, pY); particleSystem = new ParticleSystem(pointParticleEmtitter, maxRate, minRate, maxParticles, mParticleTextureRegion.deepCopy()); particleSystem.setBlendFunction(GL10.GL_SRC_ALPHA, GL10.GL_ONE); particleSystem.addParticleInitializer(new ColorInitializer(0f, 0f, 1f)); particleSystem.addParticleModifier(new AlphaModifier(1, 0, 0, 0.5f)); particleSystem.addParticleModifier(new ExpireModifier(0.5f)); gameObject.getScene().attachChild(particleSystem); Using above code the particle effect was started but when finished that I want to detect. After finishing effect I want to remove the object from the scene.

  • Is it possible to get dragging working on a Macbook multi-touch touch pad?

    - by lhahne
    I have a Macbook 5,1. That is to say that it is the only 13 inch aluminium Macbook as the later revisions were renamed Macbook Pro. Two-finger scrolling seems to work fine but dragging doesn't work. In OsX this works so that you point an object, click and keep your finger pressed on the touch pad while slide another finger to move the cursor. This causes weird and undefined behavior in Ubuntu as it seems the driver doesn't recognize this as dragging. Any ideas?

  • How should UI layer pass user input to BL layer?

    - by BornToCode
    I'm building an n-tier application, I have UI, BL, DAL & Entities (built from POCO) projects. (All projects have a reference to the Entities). My question is - how should I pass user input from the UI to the BL, as a bunch of strings passed to the BL method and the BL will build the object from the parameters, or should I build the objects inside the UI submit_function and send objects as parameters? EDIT: I wrote n-tier application, but what I actually meant was just layers.

  • World to Pixel Transformation

    - by D00d
    My objects have a location in world coordinates (basically 1.0f is a meter). If I simply draw my objects using their world coordinates, each meter will correspond to a pixel. Obviously that's not what I want. Now, I don't want to have to apply a transformation to each and every object's position when I draw them. As I happen to be using XNA, and spritebatch allows a Matrix to be passed in as an argument in it's begin method, I was wondering if there is a way to pass the World to Pixel transformation in there. Any suggestions? So far Matrix.CreateScale(new Vector3(zoom, zoom, 1)) puts the objects in their proper spot, but it also scales up the sprites. Is there a way to transform the position without enlarging the sprite? Thanks

  • What is the most appropriate testing method in this scenario?

    - by Daniel Bruce
    I'm writing some Objective-C apps (for OS X/iOS) and I'm currently implementing a service to be shared across them. The service is intended to be fairly self-contained. For the current functionality I'm envisioning there will be only one method that clients will call to do a fairly complicated series of steps both using private methods on the class, and passing data through a bunch of "data mangling classes" to arrive at an end result. The gist of the code is to fetch a log of changes, stored in a service-internal data store, that has occurred since a particular time, simplify the log to only include the last applicable change for each object, attach the serialized values for the affected objects and return this all to the client. My question then is, how do I unit-test this entry point method? Obviously, each class would have thorough unit tests to ensure that their functionality works as expected, but the entry point seems harder to "disconnect" from the rest of the world. I would rather not send in each of these internal classes IoC-style, because they're small and are only made classes to satisfy the single-responsibility principle. I see a couple possibilities: Create a "private" interface header for the tests with methods that call the internal classes and test each of these methods separately. Then, to test the entry point, make a partial mock of the service class with these private methods mocked out and just test that the methods are called with the right arguments. Write a series of fatter tests for the entry point without mocking out anything, testing the entire functionality in one go. This looks, to me, more like "integration testing" and seems brittle, but it does satisfy the "only test via the public interface" principle. Write a factory that returns these internal services and take that in the initializer, then write a factory that returns mocked versions of them to use in tests. This has the downside of making the construction of the service annoying, and leaks internal details to the client. Write a "private" initializer that take these services as extra parameters, use that to provide mocked services, and have the public initializer back-end to this one. This would ensure that the client code still sees the easy/pretty initializer and no internals are leaked. I'm sure there's more ways to solve this problem that I haven't thought of yet, but my question is: what's the most appropriate approach according to unit testing best practices? Especially considering I would prefer to write this test-first, meaning I should preferably only create these services as the code indicates a need for them.

  • What do I do when my offer letter is revoked? [closed]

    - by user-1134
    I was recently contacted for an interview by, I'd say, a top 20 tech company. I aced the technical interview and was offered an internship for the summer. I was very excited about this prospect and was very prompt in submitting required documents and forms. This was not my only offer for the summer, so I let them know I needed some time to consider. I asked if I could have two weeks and they said that was fine. Meanwhile I evaluated my 3 options. I asked the respective parties about the projects I'd be working on, work life, how hours and pay worked, housing, etc. I asked about salary and the relocation stipend. Of the three offers, this offer paid the lowest, but not poorly by any means. I inquired about the wage, challanging with a higher wage request. They declined, so, I inquired about the relocation stipend, reminding them I was coming from over seas. The recruiter said he had to check and see if they could adjust the stipend since it was originally calculated from my home address. When he got back to me, he made up some story about how after "countering their offer several times", they were implying that I was declining their offer and my the offer letter was now voided! This [more than] shocked me. I've never run into this situation before. Further, they had already presented me with a signed offer letter which stated the details of the offer, including that it was valid until date X (in the future). I immediately explained I was not countering their offer, but simply trying to evaluate all my options for the summer. I asked kindly for them to allow me the original two weeks we had agreed upon. As expected, they rejected and declined to speak with me regarding the.. misunderstanding. Is this legal? Has anyone encountered this before? Did I do something wrong? What can I do to avoid this in the future?

  • Checking timeouts made more readable

    - by Markus
    I have several situations where I need to control timeouts in a technical application. Either in a loop or as a simple check. Of course – handling this is really easy, but none of these is looking cute. To clarify, here is some C# (Pseudo) code: private DateTime girlWentIntoBathroom; girlWentIntoBathroom = DateTime.Now; do { // do something } while (girlWentIntoBathroom.AddSeconds(10) > DateTime.Now); or if (girlWentIntoBathroom.AddSeconds(10) > DateTime.Now) MessageBox.Show("Wait a little longer"); else MessageBox.Show("Knock louder"); Now I was inspired by something a saw in Ruby on StackOverflow: Now I’m wondering if this construct can be made more readable using extension methods. My goal is something that can be read like “If girlWentIntoBathroom is more than 10 seconds ago” 1st attempt if (girlWentIntoBathroom > (10).Seconds().Ago()) MessageBox.Show("Wait a little longer"); else MessageBox.Show("Knock louder"); So I wrote an extension for integer that converts the integer into a TimeSpan public static TimeSpan Seconds(this int amount) { return new TimeSpan(0, 0, amount); } After that, I wrote an extension for TimeSpan like this: public static DateTime Ago(this TimeSpan diff) { return DateTime.Now.Add(-diff); } This works fine so far, but has a great disadvantage. The logic is inverted! Since girlWentIntoBathroom is a timestamp in the past, the right side of the equation needs to count backwards: impossible. Just inverting the equation is no solution, because it will invert the read sentence as well. 2nd attempt So I tried something new: if (girlWentIntoBathroom.IsMoreThan(10).SecondsAgo()) MessageBox.Show("Knock louder"); else MessageBox.Show("Wait a little longer"); IsMoreThan() needs to transport the past timestamp as well as the span for the extension SecondsAgo(). It could be: public static DateWithIntegerSpan IsMoreThan(this DateTime baseTime, int span) { return new DateWithIntegerSpan() { Date = baseTime, Span = span }; } Where DateWithIntegerSpan is simply: public class DateWithIntegerSpan { public DateTime Date {get; set;} public int Span { get; set; } } And SecondsAgo() is public static bool SecondsAgo(this DateWithIntegerSpan dateAndSpan) { return dateAndSpan.Date.Add(new TimeSpan(0, 0, dateAndSpan.Span)) < DateTime.Now; } Using this approach, the English sentence matches the expected behavior. But the disadvantage is, that I need a helping class (DateWithIntegerSpan). Has anyone an idea to make checking timeouts look more cute and closer to a readable sentence? Am I a little too insane thinking about something minor like this?

  • How many BasicEffects do you have in a Game? What is the best way to render multiple objects/shapes at once?

    - by Deukalion
    I'm trying to understand 3D rendering and it seems that everytime you render a new object (A 3D Cube or something) you need to have a new BasicEffect for each Box you render unless you want the exact same texture? ...so if I have over a hundred boxes with each different textures, I need at least as many BasicEffects? Will that not be "too much" for the CPU/GPU in the end or result in lagging? Is there any good way to render multiple objects (cubes or other shapes) at the same time? I've tried changing the BasicEffect.Texture with each cube drawn, but it resulting in changing the first Cube's texture too. Any suggestions would be really appreciated, I'm really new to 3D in XNA so I'm trying to wrap my head around the best methods for example render a Map with objects (of shapes).

  • Will my game engine be compatible with physics engines?

    - by Bane
    My engine supports Scene handling, Cameras, and has a Renderer. Also, it has a class called Drawable, which has the position, the shape and the picture of an object. The picture property has width, height, rotation and a draw method. All game objects are supposed to inherit from this Drawable class, and are added to the Scene, along with a Map (collection of Tiles, that also inherit from Drawable), lights, and so on and so forth. The shape property of a Drawable is a Polygon, a collection of user defined vertices around the position of a Drawable (this is a relative coordinate system, so [0, 0] is the position of the Drawable. With this setup, will the users of my engine (probably only me) still be able to intergrate physics engines such as Box2DJS into their games?

  • Should I continue to pursue programming based on my experience?

    - by El Be
    The reason I ask this question is because I am not sure my troubles come from a lack of confidence, or something much deeper like lack of passion. I'm hoping experienced programmers and developers can help identify the cause of my troubles. To be brief my undergraduate major was in Computer Science, but in a small school and I had the highest gpa in my year in computer science. The first time I ever programmed was once in the 5th grade (using logo) and when I was a freshman in college. I enjoyed programming when I was in school. Then I did an internships where I was expected to produce image processing software and program microchips. I was unsuccessful and produced little results and I hated the job, because I had to figure out everything for myself, did not have any help, and there was a lot of pressure to produce results. Although I tried I could not figure out what to do and was stuck all the time and made me dislike the job. When the internship ended I went to a PhD program for computer science at a prestigious computer science school. I had a very hard time with the course, met people who have been programming since they were 6 and made plenty of applications in their spare time (which I never did, although I tried). I even met many sophomores who understood more than I did. The combination of this and other things have made me feel that programming is not for me, but sometimes I consider a career in programming. I still consider programming as a career because of the career potential (not only just because of money). Based on my experience do you believe my confidence has just been shaken and I should continue to prepare for a programming career, or do you see a lack of passion and it would make it tough to continue programming. thank you for reading and for your advice Thank you for everyone's advice so far! Also: I dropped out of the ph.D program for computer science and switched to a master's in computer graphics. Its more applied, but I still find it hard to be motivated (due to either lack of confidence or passion), but since programming is such a big field I am looking for that niche area that I feel good programming in.

  • Code testing practice

    - by Robin Castlin
    So now I have come to the conclusion like many others that having some way of constantly testing your code is good practice since it enables fewer people to be involved (colleges and customers alike) by simply knowing what's wrong before someone else finds out the hard way. I've heard and read some about Unit Testing and understand what it's supposed to do and all. The there are so many different types of bugs. It can be everything from web browser not being able not being able to send correct values, javascript failing, a global function messing up a piece of code somewhere to a change that looked good when testing it out but fails in some special case which was hard to anticipate. My simply finding these errors I learn to rarely repeat them again, but there seems to always be new bugs to be found and learnt from. I would guess maybe the best practice would be to run every page and it's functions a couple of times, witness the result and repeat this in Firefox, Chrome and Internet Explorer (and all smartphones apparently) to make sure it works as intended. However this would take quite some time to do consider I don't work with patches/versions and do little fixes here and there a couple of times per week. What I prefer would be some kind of page I can just load that tests as much things as possible to make sure the site works as intended. Basicly just run a lot of cURL's with POST-values and see if I get expected result. But how would I preferably not increase the IDs of every mysql rows if I delete these testing rows? It feels silly to be on ID 1000 with maybe 50 rows in total. If I could build a new project from scratch I would probably implement some kind of smooth way to return a "TRUE" on testing instead of the actual page. But this solution would for the moment being have to be passed on existing projects. My question What would you recommend to be the best way to test my site to make sure that existing functions does their job upon editing the code? Should I consider to implement a lot of edits first, then test manually the entire code to make sure it still works? Is there any nice way of testing codes without "hurting" the ID columns? Extra thoughs Would it be a good idea to associate all of my files to the different parts of my site which they affect? For instance if I edit home.php I will through documentation test if my homepage's start works as intended since it's the only part of my site it should affect.

  • Creating a new variable versus assigning an existing one

    - by rwallace
    Which is more common, creating a new variable versus assigning an existing variable (field, array element etc - anything that syntactically uses the assignment operator)? The reason I ask is that I'm designing a new language, and wondering which of these two operations should get the shorter syntax. It's not intended to be a pure functional language, or the question wouldn't arise, so I'd ideally like to count usage across large existing code bases in procedural and object-oriented languages like C, C++ and Java, though as far as I can see there isn't an easy way to do this automatically, and going by memory and eyeball, neither is obviously more common than the other.

  • Highlighting new rows in ADF Table

    - by Sireesha Pinninti
    About This article explains how to hightlight newly inserted rows in an ADF Table without writing any extra java/javascript code.IntroductionSometimes we may wish to give more clarification to the end user by differentiating between newly inserted rows and the existing rows(i.e the rows from DB) in a table by highlighting new rows in different color as in the figure shown below. SolutionWe can achieve the same by giving following EL to inlineStyle property of every column inside af:table: #{row.row.entities[0].entityState == 0?'background-color:#307D7E;':''}ExplanationHere is the explanation for row.row.entities[0].entityState given inside EL which returns the state of the row(i.e, New, Modified, Unmodified, Initialized etc.)row - Refers to a tree node binding(instance of FacesCtrlHierNodeBinding) at runtimerow.row - Refers to an instance of row that the tree node is based onrow.row.entities[0] - Gets the Entity row at zeroth index. In most of the cases, the table will be based on single entity. If your table is based on multiple entities then the index needs to be given accordingly.row.row.entities[0].entityState - Gets Entity Object's current Entity-state in the transaction.(0 - New, Modified - 2, Unmodified - 1, Initialized - -1,  etc.,)

  • Detecting right-click on XAML GridView control item

    - by mbrit
    Leaving aside why you would ever want to do this in a touch-centric world, here's how you tell if the right-mouse button has been clicked on a GridView in XAML/WinRT/Metro-style. You have to retrieve a point relative to the UI element you're in, and then query its properties. void itemGridView_PointerPressed(object sender, PointerRoutedEventArgs e) { if (e.GetCurrentPoint(this).Properties.IsRightButtonPressed) { this.BottomAppBar.IsOpen = true; } } (The reason why you might want to do this can be explained by looking at any of the built-in Win8 apps. You can right-click any of the items on any list to bring up a context-sensitive AppBar.)

  • Deploying, but without those pesky test files!

    - by Chris Skardon
    Silverlight testing is great, we all know that (don’t we??), we’re expected to do it as part of the development process, but once we’ve got an awesome application written and we come to deploy it, we don’t want the test files going out with it… You might be like me, have the files in a Web project – let’s face it, that’s how we’re pushed into doing it… So let’s stick with it! Now. I’m deploying via the wonders of the Web Deployment shizzle, but this also applies to the classic ‘installer’ project as well.. Baaaasically, we’re going to use the ‘Debug’ / ‘Release’ configurations to include given files. ?? OK, you know in the top of your visual studio editor, you (usually) have a drop down which predominantly reads ‘Debug’? Those are ‘configurations’. Mostly we don’t bother changing it, primarily due to laziness, but also the fact that we generally don’t see ‘Release’ as actually doing anything other than making it harder to find problems :) Well today my friends we’re going to change that bad boy… The next few steps are just helping you set up a new ‘Debug’ configuration, but you can just switch to the ‘Release’ configuration and skip to the end… First let’s go to the Configuration Manager. There are multiple ways, through the ‘Build’ menu (at the bottom), or via the drop down which currently has ‘Debug’ in it :) Got it? Select ‘New’ from the ‘Active solution configuration’ drop down: Create a new configuration, kind of like the picture below shows (or for those graphically challenged – Name: DebugWithNoTests, and Copy settings from: ‘Debug’, ensuring the ‘Create new project configurations’ checkbox is checked). Press OK. VS will do some shizzle, and in the Configuration manager, you will see pretty much exactly what you did before, only with ‘Debug’ replaced with ‘DebugWithNoTests’. Turn off the build options for the test projects. We won’t need them.. IF you skipped down from the top, this is where you’ll be wanting to stop!!! Close and now we’re one notepad step away from achieving our goals. Yes, I said notepad. You can’t do what we’re going to do in VS. (Pity). Go to the folder where your web project is, and right click on the ‘.csproj’ file. Now open it with notepad. Head on down to the ‘<Content Include’ bits, they’ll look like this: <ItemGroup> <Content Include="ClientBin\Tests.xap" /> ... </ItemGroup> Take this and modify each of the files you don’t want deployed and change to: <Content Include="ClientBin\Tests.xap" Condition="'$(Configuration)' == 'Debug'" /> Once you’ve got that sorted publish your project, once with the Debug configuration selected, and another with any other configuration (‘Release’, ‘DebugWithNoTests’ etc).. No files! Huzzah!

  • What is a good design pattern and terminology for decoupling output?

    - by User
    I have a program where I want to save some data record. And I want the output type to be flexible such that I could save the data record to a text file, xml file, database, push to a webservice. My take on it would be to create an interface such as DataStore with a Save() method, and the concrete subclasses such as TextFileDataStore, DatabaseDataStore, etc. What is the proper name/terminology for this type of pattern (I'm using the term "DataStore", log4net names things "appenders", .net they talk about "providers" and "persistence")? I want to come up with good class names (and method names) that fit with a convention if there is one. can you point me to a decent example, preferably in C#, C++, or java? Update Managed to find this stack overflow question, Object persistence terminology: 'repository' vs. 'store' vs. 'context' vs. 'retriever' vs. (…), which captures the terminology part of my question pretty well although there's not a decent answer yet.

  • Why is ComboBoxText giving me a "no attribute" error?

    - by boywithaxe
    I'm trying to add a text Combo Box into my app. I've created in and populated the list but when I I try to print out the active text I get an error.

  • Jumping over non-stationary objects without problems ... 2-D platformer ... how could this be solved? [on hold]

    - by help bonafide pigeons
    You know this problem ... take Super Mario Bros. for example. When Mario/Luigi/etc. comes in proximity with a nearing pipe image an invisible boundary setter must prevent him from continuing forward movement. However, when you jump and move both x and y you are coordinately moving in two dimensions at an exact time. When nearing the pipe in mid-air as you are falling, i.e. implementation of gravity in the computer program "pulling" the image back down, and you do not want them to get "stuck" in both falling and moving. That problem is solved, but how about this one: The player controlling the ball object is attempting to jump and move rightwards over the non-stationary block that moves up and down. How could we measure its top and lower x+y components to determine the safest way for the ball to accurately either fall back down, or catch the ledge, or get pushed down under it, etc.?

  • Another Update to SQL Server Configuration Scripting Utility

    - by Bill Graziano
    I’ve been gradually adding features to my utility that scripts the configuration of a SQL Server.  Since my last post I’ve added the following features: Skip any encrypted object in a database Script alerts, alert notifications and operators Script audits Always script model, master and msdb to capture any user-defined objects in those databases Logins are now scripted so that everything for a login is grouped together. There’s a second section in the logins that handles default databases.  In many cases a login’s default database is a mirror target and can’t be set.  This is now handled gracefully.  It also includes a separate section for all default databases so those can be quickly set in the event of a disaster. Script credentials Script proxy accounts Script database mail My goal is still to get everything outside a database scripted.  This release is enough that I can keep my mirror target servers in sync with their principals.

  • core.* files eating up server space (~50MB)

    - by skytreader
    I'm renting server space from someone and, upon logging in my control panel after quite sometime, noticed an abnormal spike (~50MB) in the disk usage. Upon investigating, I found a lot of core.* files scattered around my public_html directory. Each one is more than 5MB in size but no more than 6MB. The * part is all numbers (in programming regex, that should be core\.\d+). I downloaded one and checked the contents. There was a lot of balderdash characters (NUL mostly, but also a scattering of ETB, ETX, STX) but there's this block of readable text which says: This text is part of the internal format of your mail folder, and is not a real message. It is created automatically by the mail system software. If deleted, important folder data will be lost, and it will be re-created with the data reset to initial values. Pretty self-explanatory. A few blocks above the text are some more readable messages that look like logs but is sandwiched in between non printable characters. I've extracted some below. Scan not valid for mh mailboxes Bogus character 0x%x in news state Can't rewrite news state %.80s Error closing backup news state %.80s No state for newsgroup %.80s found Now, a few concerns: Am I under attack? The messages seem to be about my webmail but I don't use my personal webmail that much---only for a vanity email address and an inbox for an outdated comments system. However, lately, I seem to notice a spike in the spam for my vanity mail. (Note: the comments system is covered by a captcha but every now and then some get through. My vanity email has a spam filter but it isn't as good as I'd like). Next, if this is a feature, can I turn it off? Is it advisable to? I've only 150MB so you see why I'm fretting over a 50MB spike. Some final details: my only server-side scripts are in PHP. The directory which accumulated the most number of these core files is the one containing the Wordpress-managed subdomain of my site. I manage my server through CPanel. Lastly, I decided to delete this files and after some checking nothing seems amiss in my websites nor in my mail. They are indeed the ones responsible for the ~50MB spike as my disk space usage is back to expected.

  • Accidental deletion of the Gmail (IMAP) Trash 'System Label' in Evolution

    - by user20635
    I am using 11.04 and Evolution 2.32.2 I accidentally deleted the Gmail (IMAP) Trash 'System Label' in Evolution. Because this is Gmail object and (not a label per say), it is not deletable in Gmail. Under my Gmail account settings, I have made sure that both, 'Show in Label List' and 'Show in IMAP' are checked. That being said, I cannot seem to restore this IMAP folder in Evolution. I deleted the affected mail account, re-created, restarted Evolution, and no change. Any thoughts? Thanks.

    This javascript adds a method to javascript arrays that returns a boolean indicating if the supplied object is an element of the array Array.prototype.contains = function(item) { for (var i = 0; i < this.length; i += 1) { if (this[i] === item) { return true; } } return false; }; To test alert([1,1,1,2,2,22,3,4,5,6,7,5,4].contains(2)); // true alert([1,1,1,2,2,22,3,4,5,6,7,5,4].contains(99)); // false

  • Better way for calculating project euler's 2nd problem Fibonacci sequence)

    - by firephil
    object Problem_2 extends App { def fibLoop():Long = { var x = 1L var y = 2L var sum = 0L var swap = 0L while(x < 4000000) { if(x % 2 ==0) sum +=x swap = x x = y y = swap + x } sum } def fib:Int = { lazy val fs: Stream[Int] = 0 #:: 1 #:: fs.zip(fs.tail).map(p => p._1 + p._2) fs.view.takeWhile(_ <= 4000000).filter(_ % 2 == 0).sum } val t1 = System.nanoTime() val res = fibLoop val t2 = (System.nanoTime() - t1 )/1000 println(s"The result is: $res time taken $t2 ms ") } Is there a better functional way for calculating the fibonaci sequence and taking the sum of the the even values below 4million ? (projecteuler.net - problem 2) The imperative method is 1000x faster ?
