How can I execute certain code once the button on stake is hit at runtime? (in Flash CS4(AS3))

Hi
I am trying to figure out how to execute code once a button_btn is hit on stage at runtime.
Thank you for help and tips!

You can also try to create an event listener for the button itself.  (In as2.0 it was onClick or onPress or something to that effect, now I'm not sure what they are syntaxed as but there are event listeners for buttons which "listen" to see if the button has been pressed.  Mouse Events are good because it makes sure that the mouse is actually performing the action.  Don't know about accessibility with Mouse Events though since you can use a Tab key to direct input of buttons so try the Button event listeners.

  • How can I do certain things once per second?

    I need to perform things that would take more than 1 second.
    And they need to be repeated each second.
    How can I make them happen in a precise time schedule?

    A timed loop is one option, but on Windows not the best. Well, to be precise: Windows itself is no good choice if you require determinism.
    I would rather go for a normal while loop with a "Wait Until Next Multiple (ms)" wait function configured for 1000 ms. Depending on the code in the loop, you would probable "miss" iterations though....(which is also true for timed loops)

  • How can you execute a function while the mouse is over a button.

    I've got a movieclip I want to move across the screen on the x axis to the left or right depending on which button the user hovers their mouse over.
    I thought I could do this with the following:
    right_btn.addEventListener(MouseEvent.MOUSE_OVER, moveRight);
    left_btn.addEventListener(MouseEvent.MOUSE_OVER, moveLeft);
    function moveRight(e.MouseEvent):void
         sampleMovieclip_mc.x += 1;
    function moveLeft(e.MouseEvent):void
         sampleMovieclip_mc.x -= 1;
    But I find that it only moves it 1 pixel when the mouse first goes over the button and not continiously as it stays over it.  I tried using Event.ENTER_FRAME to call the moveRight and moveLeft functions, but it just keeps going and I'm not sure how to kill the function once they move the mouse off of the button.
    Any help would be greatly appreciated.
    Thanks.

    use removeEventListener() method. Here is one of the ways to deal with it:
    // move direction
    var xd:int = 1;
    // speed along x
    var xs:Number = 1;
    right_btn.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
    right_btn.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
    left_btn.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
    left_btn.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
    function onMouseOver(e:MouseEvent):void {
         xd = e.curretnTarget == right_btn ? 1 : -1;
         addEventListener(Event.ENTER_FRAME, onEnterFrame);
    function onMouseOut(e:MouseEvent):void {
         removeEventListener(Event.ENTER_FRAME, onEnterFrame);
    function onEnterFrame(e:Event):void
         sampleMovieclip_mc.x += xd * xs;

  • How can I play video by touching the button on the video thumbnail ?

    I have a table view in which if each cell is touched a video plays.
    Each cell have image of the video cell.imageView.image. And on the image I have a button (UIButton) with play symbol.
    If I touch the play button the corresponding video should be played same like the when cell is touched.
    I have a selector for the play button. But how can I know that particular row is selected by touching the play button. How can I play the video when I touched the button ?
    Thank You

    Check the hardware acceleration mode you have set. Try to use "direct" acceleration as this will choose between GPU and CPU to render and is most compatible. The setting is in the XML file generated for the app:
    <!-- The render mode for the app (either auto, cpu, gpu, or direct). Optional. Default auto -->
    <renderMode>direct</renderMode>
    And no the device is absolutely not guaranteed to record compatible video at all. Browsers go by browser standards and video recording goes via manufacturer hardware and software limits, features and compatibility. It entirely depends on what you're doing with the video and the mode it is recorded in. If the user checks off the record CIF MMS compatible video and records in that it will not be visible to many browsers. Audio is almost always recorded in ultra-light mp3 or aac so that's why you hear it.
    Android allows you to install many different browsers. Did you install any or set any other browser as the alternate default browser? When you run the video from a file manager you may be running an alternate, capable browser for the codec. AIR may use the native built-in browser. Also it may not load the video into a browser for playback at all as I would suspect a video would be mapped to the devices default media player and not a browser at all. Unless you're able to select the video and explicitly tell it to open in a browser I feel you're actually looking at the video in the "Video" app of your device, which will be compatible with the codec.
    A simple way to check browser compatibility is to copy the video to your computer, upload it to a web server and see how it plays on various desktop browsers. If any of them have black video and only play sound, you know it's a codec issue.

  • How can I make my code in the extractor just run 1x instead of on each pack

    I would like to know if there is a setting or some sort of code I can use to make sure my start routine executes after all data packages arrive.    We think it is missing data or reading it correctly because it is in different packages.

    Hi,
    If you are using function module generic extraction and using PACKAGE SIZE S_S_IF-MAXSIZE, then comment it or remove it wherever necessary. Then it should bring it in one single datapack from the source itself.
    Hope that helps. Thanks!!

  • How can i search certain music in the library of my device instead of the whole itunes library

    i want to search albums that are on my phone but when i type the name of it in the searchbar in the new itunes and the album shows up it gives me the album for the whole itunes library and not my phone im sorry if this is confusing but this is the est way i can explain

    Kirby has already summed it up nicely. If you really want to ensure, that the recipient will see the the image as an attachment and not as an embedded image, compress the file before you send it. Export the image version in the right size to your Desktop, then right-click (or ctrl-click) and use "fCompress ...." from the contextual menu. Drag the compressed file to the Mail icon in the Dock.
    Just in case, you are sending your images to Windows users and have not come across this setting, you may want to check the Mail option in the "Edit" menu: "Always send Windows-friendly attachments".

  • How can I add advertisement code into flash game?

    hi mates,
    just want to ask about loading advertisement code!
    How do you add the advertisement code (adsense) into flash games??
    my site Funny Games have over 5k games but they are getting from others sites thus I have no original files. How can I add more code into the current files?

    Unless the games were pre-made to allow you to specify some variables in the page code or some external file, you won't be having any luck... you cannot add code to the games unless you have the source files, which you apparently don't have.

  • How can I resolve error code -54 in iTunes? I am using the latest iTunes. No new updates are available.

    How can I resolve error code -54 in iTunes? I am using the latest iTunes. No new updates are available. I'm using iTunes 11.3 on a MacBook Pro, OS X 10.6.8. I can't save my library in iTunes, the message just keeps popping up.

    From an OS9 reference, error -54 is a software lock on a file or a permissions error. (Although there is no formal list of OSX error code some of the old codes still apply to OSX .)
    First, try simply restarting your computer.
    Try quitting iTunes, then deleting the .xml (not .itl !) version of the library file in the iTunes folder (iTunes will generate a new one).

  • How can I get refund codes back after deleting the e-mail?

    A mistake by iTunes had me purchase Taylor Swift's Red album for full price even though I had previously purchased a few singles. iTunes sent me an e-mail with some refund codes, but I can no longer locate the e-mail. I looked on my account under "Gifts" but they are not there. How can I retrieve these codes?
    Thank you!!

    You'll have to contact the iTunes Store again and ask if they can resend.

  • How can i stop user to get the same screen while entering same T code

    hi experts,
    how can i stop user to get the same screen while entering same T code (_Means i want user enter same t code but got different different screen how it is possible.)_
    i want to know how can we set a authorization is such a manner ...
    Through different different login id user got different different screen while entering same T-code.
    for example if there is two functional login id mum & noida...
    then user login through that and
    enter any same functional tcode (for getting purchase order)
    but get different different window...so how come it is possible.....
    plz explain in brief
    thanks in advance...plz do reply as soon as possible

    For a custom transaction this is easy, you need to ask your developers to be able to direct users to different screens based on the results of an authorisation check.  You could have an auth field e.g. ZSCREEN which is checked in the program & decides what screen the user has access to.
    For standard transactions, unless already coded, I would forget it & do what is recommended by Subramaniam and create transaction variants as required.  Assign each variant to a custom t-code and users access it that way.
    What I am interested is is why do you want to do this?
