  • Performance issues in android game

    - by user1446632
    I am making an android game, but however, the game is functioning like it should, but i am experiencing some performance issues. I think it has something to do with the sound. Cause each time i touch the screen, it makes a sound. I am using the standard MediaPlayer. The method is onTouchEvent() and onPlaySound1(). Could you please help me with an alternate solution for playing the sound? Thank you so much in advance! It would be nice if you also came up with some suggestions on how i can improve my code. Take a look at my code here: package com.mycompany.mygame; import java.util.ArrayList; import android.content.Context; import android.content.Intent; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.media.MediaPlayer; import android.os.Handler; import android.os.Message; import android.util.Log; import android.view.Menu; import android.view.MenuInflater; import android.view.MenuItem; import android.view.MotionEvent; import android.view.SurfaceHolder; import android.view.SurfaceView; import android.view.View; import android.webkit.WebView; import android.widget.TextView; import android.widget.Toast; public class ExampleView extends SurfaceView implements SurfaceHolder.Callback { class ExampleThread extends Thread { private ArrayList<Parachuter> parachuters; private Bitmap parachuter; private Bitmap background; private Paint black; private boolean running; private SurfaceHolder mSurfaceHolder; private Context mContext; private Context mContext1; private Handler mHandler; private Handler mHandler1; private GameScreenActivity mActivity; private long frameRate; private boolean loading; public float x; public float y; public float x1; public float y1; public MediaPlayer mp1; public MediaPlayer mp2; public int parachuterIndexToResetAndDelete; public int canvasGetWidth; public int canvasGetWidth1; public int canvasGetHeight; public int livesLeftValue; public int levelValue = 1; public int levelValue1; public int parachutersDown; public int difficultySet; public boolean isSpecialAttackAvailible; public ExampleThread(SurfaceHolder sHolder, Context context, Handler handler) { mSurfaceHolder = sHolder; mHandler = handler; mHandler1 = handler; mContext = context; mActivity = (GameScreenActivity) context; parachuters = new ArrayList<Parachuter>(); parachuter = BitmapFactory.decodeResource(getResources(), R.drawable.parachuteman); black = new Paint(); black.setStyle(Paint.Style.FILL); black.setColor(Color.GRAY); background = BitmapFactory.decodeResource(getResources(), R.drawable.gamescreenbackground); running = true; // This equates to 26 frames per second. frameRate = (long) (1000 / 26); loading = true; mp1 = MediaPlayer.create(getContext(), R.raw.bombsound); } @Override public void run() { while (running) { Canvas c = null; try { c = mSurfaceHolder.lockCanvas(); synchronized (mSurfaceHolder) { long start = System.currentTimeMillis(); doDraw(c); long diff = System.currentTimeMillis() - start; if (diff < frameRate) Thread.sleep(frameRate - diff); } } catch (InterruptedException e) { } finally { if (c != null) { mSurfaceHolder.unlockCanvasAndPost(c); } } } } protected void doDraw(Canvas canvas) { canvas.drawRect(0, 0, canvas.getWidth(), canvas.getHeight(), black); //Draw for (int i = 0; i < parachuters.size(); i++) { canvas.drawBitmap(parachuter, parachuters.get(i).getX(), parachuters.get(i).getY(), null); parachuters.get(i).tick(); } //Remove for (int i = 0; i < parachuters.size(); i++) { if (parachuters.get(i).getY() > canvas.getHeight()) { parachuters.remove(i); onPlaySound(); checkLivesLeftValue(); checkAmountOfParachuters(); } else if(parachuters.get(i).isTouched()) { parachuters.remove(i); } else{ //Do nothing } } } public void loadBackground(Canvas canvas) { //Load background canvas.drawBitmap(background, 0, 0, black); } public void checkAmountOfParachuters() { mHandler.post(new Runnable() { @Override public void run() { if(parachuters.isEmpty()) { levelValue = levelValue + 1; Toast.makeText(getContext(), "New level!

  • What are some Servlet Container pros and cons for a Solr installation?

    - by danieltalsky
    The SolrInstall wiki page lists seven different server / Servlet Containers compatible with Solr: Tomcat Jetty Resin JBoss WebSphere Weblogic Glassfish I'm sure that "best" is subjective, so I'll just say my criteria are: easiest to set up, best for search performance with a smallish, infrequently-updated dataset, and with the fewest number of gotchas. Jetty and Tomcat both have apt-get solr packages, so they're clearly the frontrunners for some. Jetty is used in the demo install, but there's some notes that Jetty has some difficulties handling Unicode in some cases. Tomcat is a common choice but my understanding is that it's not as lightweight and has a lot of features not needed by Solr. Is it worth considering any of the others? Are there some important pro's and cons I should be aware of?

  • I want to retrieve some information based on Caller ID

    - by Hassan Al-Jeshi
    Hello, my friend has a Real Estate company that receives a lot of phone calls everyday. He wants to have a solution such that when somebody call to his company, the operator sees all the information about the person who is calling based on the database he have right now and the caller ID. Is there a ready made software or solution that can do the job?? Since I'm a software engineer myself, I would never mind developing something from scratch or built on a ready made system (with a team of course), but I need some direction on how to start?? Notes: 1- cost is not an issue 2- the customers database is there but we never mind replacing it in a format to suit the new solution Best Regards,

  • How to find where program crashed

    - by Mick
    I have a program that crashes (attempting to read a bad memory address) while running the "release" version but does not report any problems while running the "debug" version in the visual studio debugger. When the program crashes the OS asks if I'd like to open up the debugger, and if I say yes then I see an arrow pointing to where I am in a listing of some assembler which I am not skilled enough to read properly (I learned 6502 assembler 30 years ago). Is there any way for my to determine where in my sourcecode the offending memory read was located?

  • Parallel Dev: Should developers work within the same branch?

    - by Zombies
    Should multiple developers work within the same branch, and update - modify - commit ? Or should each developer have his/her own each branch exclusively? And how would sharing branches impact an environment where you are doing routine maintenance as opposed to unmaintained code streams? Also, how would this work if you deploy each developers work as soon as it is done and passes testing (rapidly, as opposed to putting all of their work into a single release).

  • Assign weight to a integer column for Sphinx search

    - by Daniel
    Hello: I have a note table with columns: title :string content :text rating :integer and a thinking_sphinx configuration: define_index do indexes :title, :sortable => true indexes :content end Then I can search the notes and assign weights to title and content to define the order or the result: Note.search "abc", :match_mode => :extended, :field_weights => { :title => 10, :content => 3 } Now I want to assign a weight to the rating column The type of the rating column is integer. The range of the rating is [1, 2, 3, 4, 5]. Can I just add weight at the :field_weights :field_weights => { :title => 10, :content => 3, :rating => 5 } or I need to do something else to make the note which has higer rating display first?

I have found some MVC frameworks, and some of them support only PHP 5: PHP Frameworks PHP MVC Frameworks Model–view–controller on Wikipedia but can anyone recommend one of those MVC frameworks that plans to actively use PHP 5.3 features, not just being compatible with PHP 5.3?

  • How can I persist a large Perl object for re-use between runs?

    - by Alnitak
    I've got a large XML file, which takes over 40 seconds to parse with XML::Simple. I'd like to be able to cache the resulting parsed object so that on the next run I can just retrieve the parsed object and not reparse the whole file. I've looked at using Data::Dumper but the documentation is a bit lacking on how to store and retrieve its output from disk files. Other classes I've looked at (e.g. Cache::Cache appear designed for storage of many small objects, not a single large one. Can anyone recommend a module designed for this? EDIT. The XML file is ftp://ftp.rfc-editor.org/in-notes/rfc-index.xml On my Mac Pro benchmark figures for reading the entire file with XML::Simple vs Storable are: s/iter test1 test2 test1 47.8 -- -100% test2 0.148 32185% --

    I am getting the message: * _NSAutoreleaseNoPool(): Object 0x3f43660 of class UICFFont autoreleased with no pool in place - just leaking I have placed a break point using the symbol _NSAutoreleaseNoPool and the program does break, however, the stack trace does not show me any of my code only some UIView and Core Animation layer code. Is there a better way to get to the bottom of the issue? There is apparently a thread that does not have an auto release pool, but I can't figure out where. Thanks.

  • How to represent a Many-To-Many relationship in XML or other simple file format?

    - by CSharperWithJava
    I have a list management appliaction that stores its data in a many-to-many relationship database. I.E. A note can be in any number of lists, and a list can have any number of notes. I also can export this data to and XML file and import it in another instance of my app for sharing lists between users. However, this is based on a legacy system where the list to note relationship was one-to-many (ideal for XML). Now a note that is in multiple lists is esentially split into two identical rows in the DB and all relation between them is lost. Question: How can I represent this many-to-many relationship in a simple, standard file format? (Preferably XML to maintain backwards compatibility)

  • Accessing properties through Generic type parameter

    - by Veer
    I'm trying to create a generic repository for my models. Currently i've 3 different models which have no relationship between them. (Contacts, Notes, Reminders). class Repository<T> where T:class { public IQueryable<T> SearchExact(string keyword) { //Is there a way i can make the below line generic //return db.ContactModels.Where(i => i.Name == keyword) //I also tried db.GetTable<T>().Where(i => i.Name == keyword) //But the variable i doesn't have the Name property since it would know it only in the runtime //db also has a method ITable GetTable(Type modelType) but don't think if that would help me } } In MainViewModel, I call the Search method like this: Repository<ContactModel> _contactRepository = new Repository<ContactModel>(); public void Search(string keyword) { var filteredList = _contactRepository.SearchExact(keyword).ToList(); } I use Linq-To-Sql.

  • proper fill an image larger than screen

    - by madcat
    what I wanted to achieve here is simply fit the image width to the screen on both orientations and use UIScrollView to just allow scroll vertically to see the whole image. both viewController and view are created pragmatically. the image loaded is larger than screen on both width and height. here is the related code in my viewController: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } - (void)loadView { UIScreen *screen = [UIScreen mainScreen]; CGRect rect = [screen applicationFrame]; self.view = [[UIView alloc] initWithFrame:rect]; self.view.contentMode = UIViewContentModeScaleAspectFill; self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; UIImage *img=[[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"image" ofType:@"png"]]; UIImageView *imgView =[[UIImageView alloc] initWithImage:img]; [img release]; imgView.contentMode = UIViewContentModeScaleAspectFill; imgView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [self.view addSubview:imgView]; [imgView release]; } tried all combinations for both contentMode above, did not give me correct result. the most close I am getting now: I manually resize imgView in loadView, portrait mode would display correctly since app always starts with portrait mode, but in landscape mode, the width fits correctly, but image is centered vertically rather than top aligned. if I add the imgView to a scrollView, in landscape mode it looks like contentSize is not set to full image size. but when I scroll bounce I can see the image is there in full size. question: why I need to resize it manually? in landscape mode how and where I can 'move' the imgView, so imgView.frame.origin is (0,0) and works correctly with a scroll view? Thanks! UPDATE: I added: imgView.clipsToBounds = YES; and find out in landscape mode the image bounds is smaller than screen in height. so the question becomes how to have the image view keeps original ratio (thus shows the full image always) when rotated to landscape? do I need to manually resize it after rotation again?

    I have just learned how to use the SQLite database for local storage in a Webkit web browser (e.g. Google Chrome or Apple Safari) using the Javascript API. For example the "Sticky Notes" application. However, I know that SQLite has a function called sqlite_create_function() that lets you add custom functions to your instance of SQLite on the fly which can then be used inside SQL queries. This function is described at sqlite.org. I also know that you can call an equivalent of this API in Ruby as described here. QUESTION: Can anybody show me how to do this in Javascript - i.e. write a custom function in Javascript that can be bound into the SQLite database at run time to be called by the SQLite engine, and all inside a Webkit browser?

  • Is there a way to localize input type="date" in HTML5

    - by lambacck
    I know that at the time of this writing only Opera supports a browser UI for <input type="date" name="mydate"> and maybe my attempts to localize this field have been met with frustration because niceties like localization have not yet been included in their implementation, but I don't even see mention of it in the HTML5 spec. Is there a way that localization should be specified? Should I do lang="fr" on a parent element? Some notes on the implementation of the site in question: Localization (language) is explicitly picked by the user because they are managing data in multiple languages and it is not reasonable to expect that the user's browser chrome is in the language being viewed or that the browser is providing desired language request headers. I want to be sure that if the page is rendered in French that the date picker provided by browser chrome shows options that make sense for French language. The plan is to fall back to jQueryUI for browsers that do not support type="date", I will use the detection mechanism provided in Dive into HTML 5

  • SQL to return the rownum of a specific row? (using Oracle db)

    - by jedierikb
    In Oracle 10g, I have this SQL: select dog.id as dogId from CANINES dog order by dog.codename asc which returns: id -- 204 203 206 923 I want to extend this query to determine the oracle rownum of a dog.id in this resultset. I have tried select rownum from (select dog.id as dogId from CANINES dog order by dog.codename asc) where dog.id=206 But this does not work out very well (it returns 1 no matter which dog.id I match on). I was expecting to get back 3. Thanks for your help! Notes http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html I am pretty sure I do not need to use rowid

  • echo "-e" doesn't print anything

    - by wheleph
    I'm using GNU bash, version 3.00.15(1)-release (x86_64-redhat-linux-gnu). And this command: echo "-e" doesn't print anything. I guess this is because "-e" is one of a valid options of echo command because echo "-n" and echo "-E" (the other two options) also produce empty strings. The question is how to escape the sequence "-e" for echo to get the natural output ("-e").
