Global and Local variable... why it doesn't work?

I'm confused.  .__.

haha

in any case, I wrote a class for my AS3 flash game.  It's that everything works well until what I called a method and got an error message.  After a bit of debugging, I was able to determine that my problem is when I try to assign a global variable (and the class property) to a local value, within the service itself, where the local variable.

Here is part of my class:

Sheet/public class extends Sprite {}

private var number: int;

private var sourceBitmap:Bitmap;

private var sourceBitmapData:BitmapData;

private var tileWidth:int;

private var tileHeight:int;

public void {sheet (number: int, tileWidth:int, tileHeight:int)}

This.Number = number;

this.tileWidth = tileWidth;

this.tileHeight = tileWidth;

displayImage();

init();

}

public void displayImage() {}

var imgLoader:Loader = new Loader();

imgLoader.contentLoaderInfo.addEventListener (Event.COMPLETE, done);

If (number > = 100) {}

imgLoader.load (new URLRequest("CharSprites/Female/"+number+".png"));

}

else {}

imgLoader.load (new URLRequest("CharSprites/Male/"+number+".png"));

}

function done(evt:Event):void {}

var myBit:Bitmap = Bitmap (imgLoader.content);

addChild (myBit);

this.sourceBitmapData = myBit.bitmapData;

trace (this.sourceBitmapData);                                              ... sourceBitmapData are here

}

}

private void init() {}

trace (sourceBitmapData);                                                       sourceBitmapData is null here

}

}

}

I thought that I was able to assign the value of hard bitmapData to a property class (global variable) inside a function and have it exists outside.  I was wrong?

How do I get around that?

I know that I can write a function to return the Bitmap image, but as the function is called after the EventListener and depends on my charger, I don't know how to get around this problem.

Thank you very much!

Ya. My recommendation is to delay your init() function call until your image will load. So just move the call to init() in your service done or what needs the bitmapData to your function made move.

  • Movement of mask and the track Matte Question - why it doesn't work?

    Hi first gurus...

    I am able to use the first titration module - to create a mask - then the Luma put on the effect of TrackMatte to isloate a region of the video (I duplicated the original) which I am interested.

    -By of many tutorials/videos online, I've found.

    Question: Why - can I not use the mask / "exit" from the ThreeWayColorCorrector to do the same thing?

    Image - duplicate the clip - drop the ThreeWayColorCorrector - using "High color" mode - to isolate people form (from an extract of the interview);  the background is black... the contour hair root and the body of the interviewee is white.

    I get white/black - because I passed the exit of the ThreeWayColorCorrector to 'mask '...

    Now - when I drop this clip on my video editing - that I use for the TrackMatte effect - it does not work as I had expected, it could - at all...

    Very disappointing - it would have been a very powerful way - to create a mobile cache to work with the TrackMatte effect...

    If someone has done something like this before? Y at - it an easy solution - or a setting that I missed...

    This should work really - not?

    Some information:

    I work with a GreenScreen shot - with lighting poor to separate the hairline of the screen.

    Work with green screen - subject to blonde hair.

    I thought that the retro-lighting/hairlight was not necessary - I was wrong.

    Now with the green screen hidden using this ultra key - get jagged effect around the airline and what looks like the snow and noise around the fringe.

    I thought en - 1) video duplication and combining with effect 2) TrackMatte - use a mobile mask that matched just the root of the hair/plan - I might be able to blurr the edge enough to get rid of the unpleasant effect I see...

    As BIG as the UltraKeyer is - different parameters of transparency/spill/Starter/soften seem not to be able to remove the ugly/noticeable hairline artifacts that I see...

    New - look like jagged effect / snow...

    Any thoughts?


    Thank you

    In my opinion, the track-bearing on Pr capabilities fall away from the brand.  The fact fcp7 as it is very useful.  The limitation of the matte in public relations is that the mast is adjusted on the layer is hidden.  You can animate and change the scale and position of the track matte layer, but if you want it to run in smooth synchronization with the matted layer, you're in for a bit of work.  Ideally, you should be able to pan and adjust the layer being hidden inside a motionless mask.  Can-do that elegantly in PR.  This is a faulty design of the Pr, IMO.

    As a general rule, you must go to EI for the good contols, where you have all the power of masking you need, with the exception of the variable feathering, and who is rumored to be included in AeCS6.  Also it would be nice to be able to follow the points of mask, which is not currently in Ae either.  But that's another debate.

    That said, I am able to use the mask to a secondary use as a Luma matte.  Not sure why it does not work for you.  Have you played with the secondary commands sweetness?  I couldn't even be after what is your problem.

    However, here is a tip that I use with Ae that might work for your problem of inlay.  Use two instances of the Keyer.  Use all first to create a "garbage" key, where you will have the most greenery, leaving only a border around your subject.  Then, you can use the second instance of the Keyer to hone in on the edges.  Give it a shot.  Might work for you.  This method gives you an option to avoid the harsh cleanup settings of Matte with eradicating all the Greens in a framework.

  • Global and local index with respect to table partitioned

    Hello
    I am very confused about local and global index in a partitioned table.
    In addition, local index can be partitioned and unpartitioned.
    In addition, what is the difference between global partitioned and unpartitioned
    the index?

    As far as I know,
    If there is local index then there will be as many partitions as the partition table
    and local parition will index contains the index of only the lines of their corresponding scores.
    In addition, the local index maintananence is easier because drop us or create a partition, only index corresponding partition is affected then that in the case of the overall index,
    If we create a new partition of the table, to rebuild the global index.
    Am I wrong?

    Concerning

    Hello

    This means that when you add/drop/split/merge table any partition (maintaiance) lying below, its corresponding partition in index is automatically added/deleted/split/merged. Oracle takes care of it internally without user intervention.

  • global or local variables for speed?

    Hi, someone at - it an idea?

    is it faster to the use of global variables or properties (sprite) or the properties of the object?
    In other words is it smart to use as less globals possible or not (in terms of speed)? Or is not a difference.

    Thank you!

    www.SeriousGames.startpagina.nl

    In general, use the globals less possible, for various reasons (lighter &)
    more secure code, ability to reuse the names etc.).
    In terms of speed, local variables are faster in most of the languages
    (definition hierarchy, local verified first + entered less to research)
    (for). In Director however, no difference will be hardly noticeable, since
    the charge of executing line jargon leaves no room for sub or nearby to
    considerations of optimization nanoseconds.

  • Why transfer doesn't work?

    Hey, guys! Hoping someone here can help me. I am the proud owner of a Macbook (early 2015) of the retina, and I love it. I want to say that it was no problem, but I Can not - transfer does not work!

    I logged in iCloud by using the same Apple ID on my iPhone (iPhone 6 s, iOS 9.3.3) and when I log in Messages on my Mac, I keep seeing in the left panel under 'Preferences' that my account is inactive. Whenever I try to send a message to someone, the name comes in red and I'm invited to sign it - except when I hit the sign in button, I'm actually still signed in and the account is activated! I take a glance settings iMessage on my iPhone and noticed that there is no option for transmission of Message text, so it was not possible to activate this feature.

    I called Apple Support and they also found it strange that he did not work, they find more strange was that "I had all the ingredients, but it does not work" - which means, I am connected with the same ID, my number appears in the preferences of Message on my Mac, I signed with my identifier Apple to use iMessage on my iPhone... it's weird. The next day, I noticed that some aspects of the transfer procedure worked.

    Every time I open Safari on my iPhone, it appears in the Dock on my Mac and vice versa. It goes the same for mail. I also noticed under "phone settings" on my iPhone, I had the opportunity to receive calls on my devices to iCloud, which listed my Macbook. I thought: 'very well! an improvement! "Later, I invited to enter a PIN code of my Mac on my iPhone and voila! Transfer text messages was there, I entered the code and then prayed. Back to the start box, Messages on my Mac refused to work. I kept getting the same problem as above. I must point out that Safari, Mail and phone were still working through transfer.

    Today, I noticed nothing work - no mail, no phone and no Safari by transfer. The option to respond to calls on other iCloud devices have also disappeared.

    When I contacted Apple, I was put with a counselor... but I have not heard yet return. He was also puzzled over there (but very useful). The impression I get from Apple, this is a problem at the level of the device. I'm not so convinced, I'm thinking it was to do with my account on the end of Apple (perhaps the Server/service level?). To my knowledge, Apple Support and specialist have not looked into this.

    Here is what I tried:

    1. Turning iMessage/Facetime on my iPhone on and outside.
    2. Signature on my Apple ID for iMessage and Facetime and then signing back in.
    3. Disconnection and signature in Messages and Facetime on my mac.
    4. Signing in and out of the iCloud on my iPhone and Mac.
    5. Restart both devices when they are disconnected from the internet.
    6. Tried the signature using the App password. (did not work)
    7. Off the two-step verification. (that is, one more time)
    8. Signature on all of my Apple ID account by using only my email domain iCloud.
    9. IPhone restored like new.
    10. Recovery of the Internet on Macbook.
    11. Checked my iPhone automatically sets the time zone.
    12. To ensure that the region iMessage/Facetime and iPhone/Mac were the same (United States)
      1. I must emphasize that the region of my ID Apple is set to Barbados (where I'm from) so that I can use my local iTunes/App Store purchases credit card but I don't see how or even why it would affect the transfer procedure
    13. At the request of the Senior Adviser, I called my provider wireless (flow Barbados) to understand if they support the text Message Forwarding (they didn't know what I was talking about, first, that they said no encryption, it wasn't like call forwarding, and then when I explained to them, they said they were not sure and contact Apple even once).
    14. I don't know if this has nothing to do with it, but I find my iPhone refuses to connect to my MacBook via bluetooth after mating, my MacBook would say connected and my iPhone say not connected, and finally he would be dismissed. But sometimes it does not work when I use the Handoff... weird apps. Also, I can't seem to get AirDrop works, does not detect my devices between them. Just said that I would mention this in case it helps.

    Honestly, this has me has raged for a few days now and I'm really at a loss as to what I should do.

    Any ideas or suggestions? Whatever that either would be appreciated.

    UPDATE: transfer of telephone, Mail and Safari doesn't work again... still no luck with Messages.

    I have a few updates with screenshots, hope they help.

    So, I get this message when I connect using the same Apple ID on iMessage on my iPhone and iCloud/Messages on my Mac.

    When I signed, what happened. I was able to sign properly.

    As you can see here, my ID Apple is connected and my number is recognized. Note, it continues to tell me that iMessage inactive (red underlined).

    When I try to send a message to myself (even with other known users iMessage), this is what is happening.

    For some reason, the recipient turns into this red box, where is my Apple ID is the box and I am being asked to activate my account of iMessage. When I click the activate option, I see that I am connected and the ID is activated.

    This continues to baffle me.

  • variable cluster shared doesn't work not as expected

    Hi all

    I use shared variables for communication between a computer host and target time real crio.  This works well as simple variables.  I configured a set of shared variables in an attempt to clean up the code a bit.

    I have some problems.  If I write to a single element, for help, the other elements of the cluster that I don't want to not write to are replaced with unknown default values.   Second, when the host program is stopped, the cluster on the host computer RT wrote what appears to be default values for all variables of the cluster on the RT.  The idea is to keep the RTW program running in its current state until the host computer retrieves.  Of course, this is impossible, if it resets all default data.

    It seems that I can only write to a cluster on one side and read on the other side.  I can't read/write in the same cluster at different points on the host machine and target.  With a shared variable, I can read/write to my hearts content on any process.  I could not find a way to solve this problem.

    I'll post the code, but you will need a cRIO to run it.  If someone uses the cluster shared variables, I'd be curious to see how you do.

    Thank you
    John

    That makes sense, I can think about is that you write on the same cluster in two different places. Each location will update the two values so if the host writes B1 = False and B2 = True then the Rio writes B1 = False and B2 = False, then the variable will be set to the most recent of the two being false. It's a loop condition.

    Even if you only set a value in the bundle name the another value from the cluster to a package of entry by name.

    To manage this, you'll need to remove the cluster to enter the bundle name and replace it with the shared variable read. This is where you need a time to make sure that the variable has the most recent value updated.

    Also, you still have the stress points. For the shared variable try linking to the custom control instead of an indefinite cluster (choice according to below in the setup of the SV)

  • Why youtube doesn't work anymore without setting 'security.ssl3.rsa_rc4_128_sha' in real life?

    After that it turns rc4 is safer, I changed all the security.ssl3 - variable containing the substring from rc4 to false. Still, everything worked well, including youtube.
    But 2-3 weeks, youtube has begun to make problems: about 70% of the time, the first video is clicked on, gave an error. I had to delete the cookie (although I don't know if this was really necessary) and reload the page. After a few tries, it would eventually work and no so all video-subsequent requests, until I closed firefox (and therefore remove the cookie) or remove the youtube cookie. It was kind of annoying, but videos always occurred after a few tries.
    Since the middle of this week, the described method no longer works. I understand, now I have to allow rc4 again, by changing "security.ssl3.rsa_rc4_128_sha" to true. I don't know if the error is due to firefox or google/youtube. I meen why google would downgrade to only allow a non secure encryption method? On the other hand: there are updates in firefox affecting the rc4?

    So my questions are: which side is the bug? And is there no workaround safe solution to ban rc4 once again, while using youtube?

    It is a problem with the server that hosts the video files and Google has chosen to only support what a costume (speed issues?) figure even if the server supports TLS 1.2 according to the test report, but I don't know if that makes a difference instead of using SSL3.

  • Trackpad acting odd.  Insensitive to touch and top with 1/3 doesn't work.

    HI, my Macbook Air is just by its care of apple for 3 years and the trackpad has starting acting weird.

    It is very sensitive to the touch and the top of page 1/3 in particular is almost dead, unless you rub hard.  He gets very nervous to use, and it has now got to the point, it is unusable.

    Another side effect, it seems that the keyboard is blocked sort of as if SHIFT CAPS LOCK is activated when the trackpad is odd.

    If I connect a magical mouse and disable the trackpad, and then it works fine and no problems with the keyboard.

    So my thought was the trackpad is defective.  I bought a new replacement apple trackpad and replaced it thinking that would solve the problem, but it's exactly the same way - so it doesn't seem like the trackpad and would point to something between the trackpad signal and I think that... the card mother maybe?

    Any ideas?

    Thank you

    Hi carpediembill,

    I understand that your MacBook Air trackpad behaves erratically. Fortunately, we have an article (link below) which details what to do in such a situation.

    It has been determined that the computer is properly set up and should work with Movie Maker 2.6, but it does not work.  (It uninstalled and reinstalled through microsoft download this morning.)  I have never been able to run Movie Maker and don't know why.

    I checked the hdmi cables with other devices and work on the two TV - using the shortest cable to test the laptop.
    honestly, I thought that it was a software problem because it can real detects the TV but no picture or sound work, which indicated the hdmi cables, but they work with my ps3.

    any help much appreciated sincerely.

    Hello

    If all goes well he material s no problem, but I m afraid it could be
    I think it might be a hardware problem, because you said that you have already configured the laptop back to factory settings and this has not solved the problem.

    I understand this correctly? You used the recovery disc or HARD drive recovery?
    Is this good?

    What you could do is to check if your BIOS is up to date.
    On the European driver Toshiba page, you will find the latest version of the BIOS.
    Check if you can update the BIOS.
    In addition, I recommend setting the BIOS to default and settings to save the changes.

    At least a graphics card driver might be updated also. Its worth a check however, I m really not sure if this might help you
