AS3 Motion Code

I am using the AS3 Copy Code as Motion. All works good but I need to listen when the motion is Ended or Complete. I looked through the help docs under AnimatorFactory and MotionBase but unable to find any Events on these two. What I want to do is listen for the Notion to be completed then do something. Any ideas?
Thanks

the animatorbase class has a motionend event.

Dynamically creating a AS3.0 code based on animations made at runtime

Hello everyone,
I am new to AS3.0 and always getting tasks that is very very challenging. Here is the challenge.
Need to create a flash application where the user can create animations using images(upload) and text dynamically and export to a swf file. This was my previous post and the answers from the forum members was "impossible - 95%" and "Possible - 5%" (my average calcu).
http://forums.adobe.com/thread/678202?tstart=0
Now i got an idea from the "Possible - 5%". That is
as per the discussion in the above link there are compliers that can create swf files from the command prompt using haxe, swfmill, neko etc etc. these requires a AS3.0 class file to get the output.
now my question is can we generate the AS3.0 code from the swf file where the animations using images, text are done on the runtime stage. after the user is done with his animations he can click publish btn were we need to create the AS3.0 code and send to the command promt for getting the swf file as output.
i think this task is quite hard. but any help regarding this will let me in a right direction.
thanks in adv for any helps

Assuming that WYSIWYG concept is valid, you are better off with Flex. Flex offers xml structure that you can use as template and just write values. Then this XML can be used by compiler as it is used in Flex.
In any case, this is a very tedious and advanced task you are embarking on. If you are talking about couple of objects and simple animations - it is not that bad. But if there is more - it is difficult mainly because of the multitude of use cases and exponential growth in objects relationships from both display list and user interaction standpoint.
I was a part of such project about 2 years ago and I see that one has to be an excellent UX engineer, very good architect and an advanced AS developer in order to make this kind of application worth pursuing.

Global vars in as3 and code run order

two questions:
1)how can i declare a global variable in as3, like in as2 i
could write for example :
_global.variableName = "variableValue"
and then access the var from anywhere.
2)how can i tell a part of the code from the root to run only
after the code ran in all the other movieclips when the swf loads?
thx

As far as the first irem goes... AS3 does not support the
_global reference. Just Google "AS3 _global" and you can probably
find a few options. Here's one result:

AS3 preoloader - code overload

Is there an easier way to create a custom preloader animation
in AS3? The
only information I can find on the web tends to have about
two pages of code
with stuff like "packages" and "public/private functions"
which I've never
used and unfortunately do not understand. The idea seems
simple to me [(var
ratio = (bytesLoaded/bytesTotal)*100) then have a movie clip
(load_mc) one
hundred frames long displaying 00-99 respectively for each
frame. Then find
some way to call a function that says
[load_mc.gotoAndStop(ratio);]. I've
seen AS2 tutorials on this subject and they all kinda follow
this general
idea. Why then in AS3 do you need two pages of code for an
action that
required 5 or 6 lines of code in a previous version of
ActionScript (AS2)?
No..no...sorry that's not my question. **sighs** I just need
to know if
there is an easier-to-understand method to creating
prealoaders in AS3? I'm
making an intro movie for a new website and the final swiff
will probably be
close to 1 MB so I want to display a simple loading animation
instead of a
blank screen. Any help is greatly appreciated.

I saw this first over in the AS1-2 forum. You'll find my
answer there.

Yes, AS3 can look very complex, and many times it is. You
don't need to create packages to use AS3. You can, but you don't
have to. Writing classes in packages allow you to create libraries
of reusable code. You can just write code that will work for you in
a frame script space in a layer of your movie. In many cases, and
for simple movies, this works just fine.
To create a preloader animation, you can use the UILoader and
ProgressBar classes. You can also use the Loader class. Here's an
example that uses the Loader class:

Need help with as3 for popup window

I am nearing the end of the semester in my Flash Animation class. I have learned very simple AS3 things, code snippets etc. I am trying to find the actionscript for coding a very simple popup window, but have not found a clue.
Here's what I want to do...I have a white box with some type on the stage. When a person clicks on the white box, I want a popup to open that is larger, that will contain the same type but larger. That box will have an x so it can be dismissed. I don't want to do this in html, only in Flash CS5. I don't want a browser window, I just want a bigger version of the smaller box. I know how to build both boxes, just don't know how to write the code. I know there will be an on-click mouse event listener, and then I am lost.
Can anyone help with the code I might use? It would be most appreciated.

It would be something along the lines of... (using instance names relative to your description)...
popup.visible = false;
whiteBox.addEventListener(MouseEvent.CLICK, showPopup);
function showPopup(evt:MouseEvent):void {
popup.visible = true;
popup.popupX.addEventListener(MouseEvent.CLICK, hidePopup);
function hidePopup(evt:MouseEvent):void {
popup.visible = false;

AS3.0 Need to Store Radio Button Value as SharedObject

I am under a tight deadline. Friday Aug.22!!! I am trying to
store the value of a radio button (in a group for yes/no) when a
'Next" button is pressed. I have a nextBtn.addEventListener(...) to
contain a function which holds code to store the value of each
radio button on the page into its own SharedObject. As such:
_so.data.DrugName1 = DrugName1.selected;
I do not know the AS3.0 code to get the value of the selected
radio button in a grouping and then to use that value and store it
into the SharedObject _so.data I have been banging my head for
days. I fear I keep trying to use AS2 code for an AS3 project.
AAAAAhhhhhhhh!
Can someone please help me determine the value or data of a
radio button or radio button group. Is it "selected" or
"selectedData" or "getValue()" or "value" or "data" or what ??????
I don't know where else to turn. :(

Please email direct if you can help. I'll be sure to re-post
a solution once I get it.
Thank you in advance.

FlashTastic, thanks for the reply. I entered the code but I
cannot get the values to repopulate in the page when I return. I
try to put the SharedObject data of the radio button back into the
button on the page but it will not take. Here is my code:
//*************code in page to load SharedObject value back
into radio button when the page loads if a value
exists*****************
if((HumiraY_Row1.selected == false) &&
(_so.data.HumiraY_Row1 != null)){HumiraY_Row1.selected = true;}
if((HumiraN_Row1.selected == false) &&
(_so.data.HumiraN_Row1 != null)){HumiraN_Row1.selected = true;}
//******** Here is when the Next button is pushed to save the
data***
nextBtn2.addEventListener(MouseEvent.CLICK,
mouseDownHandler2);
function mouseDownHandler2(event:MouseEvent):void {
if(HumiraY_Row1.selected == true){_so.data["HumiraY_Row1"] =
HumiraY_Row1.selected;}
if(HumiraN_Row1.selected == true){_so.data["HumiraN_Row1"] =
HumiraN_Row1.selected;}
Still stuck. Look forward to another post. :)

Compiling an existing as3 packag with flex sdk (for a flash/flex/as beginner)

Hi
I am new to flash, flex, mxml, and actionscript (with a strong background in c, python, and scheme and some background in Java, VBA, and Javascript). I have a website for which I would like to develop some simple swf content. Basically, I would like to load esri shp files at runtime (and display a series of them as an animation) using these APIs.
I have read through some flex getting started material, but I have found that there is no better way to learn a framework/language than to look at and modify existing code. Happily, I've found a sample that is both salient to my project and about the right level of complexity.
I have the Flex SDK 3 and have created some simple movies. However, I haven't managed to compile the example as3 source code to a successful swf movie. I'd like to write mxml for layout/structure and as3 for functionality, and compile with mxmlc, period. Most examples I've found use of Flex Builder, Adobe Air plugins, other IDEs, etc and so they aren't very helpful.
Here is a link to the content I'm interested in, and more importantly the as3 source packages (zip or browesable) that I'd like to compile. There are two: ManualCartogramTest.as and USStatesCartogramExample. I can use mxmlc to compile either one sucessfully, but the resulting swf file displays nothing. It seems that I should use the ManualCartogramTest class to create an instance of it, but none of my efforts have worked.
Can anyone help out? How should I generate the swf movie given one of these packages? What key piece am I missing?
Jeff
For completeness, here is another example using the shp/dbf packages (from the creator) that I just can't figure out what to do with.

1. Perhaps this wasn't the right forum.
2. I had to use set -use-network=false to enter "local-with-filesystem" mode. Unfortunately, it took a while before I finally used a flash player that told me the problem instead of silently failing. The linux standalone or linux debugger from adobe was key! Gnash, swfdec, and my firefox plugin hid the problem.

Change HTML background color with AS3

Hi all,
I'm looking or a way to change my HTML background color trough Flash.
The problem is it's not working any ideas? here is the code i'm using
HTML HEAD
<script language="JavaScript">
function changeBgColor(newBgColor)
if (window.document && window.document.bgColor)
        document.bgColor = newBgColor;
</script>
Flash document
import flash.external.*;
var jsCall:String;
this.addEventListener(Event.ENTER_FRAME, bgChange)
function bgChange(e:Event):void{
    jsCall = String(ExternalInterface.call("changeBgColor", "#FF0000"));
best regards!!!

Change your AS3 function code to be more like...
function bgChange(e:Event):void{
    var result:Object = ExternalInterface.call("changeBgColor", "#FF0000");
and I suggest you do not use...
this.addEventListener(Event.ENTER_FRAME, bgChange)
as that will continuously trigger the function call at the frame rate of the Flash file. If the intention is to only trigger it once, then just use...
bgChange();

Run AS3 script via html codetag?

From what I know, it is possible to add <a href="....">
or <a href="mailto:..."> in order to set dynamically a
specific substring of a text to do either navigation to other page,
or open to e-mail client. But is it possible to do much more
important things, by just calling an AS3-function?... I am talking
about a hyperlink to AS3 script code, instead to email client /
browser.
I.e. I want to download dynamic text with the names of
Authors of papers from a database, and parse them serial i.e.:
Authors:
Author1Name,
Author2Name, ...,
AuthorKName".
When the user press on a name, to open a vector flash pop-up
(MovieClip) as a data-card of the specific Author. This could be
done if there was an Flash-HTML tag like <a
fref="loadModule(1)">
Author1Name</a>, which would run the
loadModule(1) function of the parent MovieClip that contains
the dynamic text.
I know something like this doesn't exist (
add it to wishlist for future versions! :) ), but is there
any other way to do it, except from creating one Object per author
with MouseEvent listeners and place them dynamically to correct x,y
positions?...

It's as you describe it, with one problem: the "button"
position and size is dynamically text-depending and not known
before the data parsed to screen.
Example:
Create a textField and add inside it a dynamic text like:
"Bill Gates created Microsoft". If this text was static I could add
2 transparency buttons (listening to: MouseEvent.CLICK), one over
"Bill Gates" and one over "Microsoft", where the first would make
visible a movieclip talking about Bill Gates, and the second would
make visible one movieclip talking about Microsoft.
But the text can come as: "Microsoft was created by Bill
Gates", or "There is a company named Microsoft, which was created
by Bill Gates", or "Windows is a software created by Microsoft.
Bill Gates was the one that created Microsoft". Thus you can't have
apriori knowledge on where to put the buttons. In more advanced
examples, I might not know how many buttons I should place also
(i.e. of authors - i don't know apriori how many authors a paper
has).
This is same as in case of hyperlink: We don't know where a
hyperlink can be, thus we place a tag for every hyperlink into the
text that defines that hyperlink position and action.
The only way to overcome this problem (just though of it) is
to create my own tag, and before parse the text to check for that
tag. For every tag to find the starting coordinates of it's inside
text on the parent movieclip (x,y) and the ending coordinates - and
providing that they have the same y-coordinate (no line change), to
create a transparent button at the specific area over the text.
If this is the only way to do it (thus making my own
pseudo-html tag inside flash),
I must know if it is possible to take (x,y) coordinates (in
pixels) of a letter (upperleft corner) in a dynamic textbox.
kglad, do you know if this is possible and how to do it?... (It may
need to open new thread for this)...

Motion with windows xp embedded

I am trying to get some motion code to run under the Windows XP embedded Op system.
Has anyone any new knowledge from that existing in the forum?
If so can anyone possibly give me a blow by blow account of how to get some sample CVi motion code running on an embedded system?
Also how do I configure Write Filter to allow the minimal system to run from Flash or Solid State Disk?
Many Thanks
All comments and experiences from my development will be shared back to the forum.
Mike..

Mike,
I understand your concern and I'm passing this request to R&D to evaluate their future development.
LabVIEW RT now supports also Motion and Vision, this have been added in the near past to the RT product line.
Since you are mandated to use LabWindows/CVI, my suggestion will be to either have a PC, but running onboard programs in the motion controller, in this way you are running your program on an RT-OS, and as long as your computer is turned on it will be working.
The other suggestion is to have a firewire controller, the FW-7344, together with the onboard program feature, with LW/CVI you can program your application, download it to the controller, and just disconnect it from your computer, you can leave the "box" working as a stand-al
one instrument.
I hope this helps, if not hopefully you will find an answer from someone else here on the forum. Good luck!

HELP! Continuous Object Motion When Mouse Moves Over - ActionScript 3.

Hello! I'm working on a school project. Below is an image of what I am working on.
My cursor in this movie is the heart. When I move my mouse over Hello Kitty she jumps -- but only once. How can I get her to keep jumping when my mouse is over her, and make her stop jumping when I pull away? Here is the code below. If you can help that would be great!!!
Also, because I am new to ActionScript I might have messed up with the motion of the animation. Hello Kitty used to jump continuously without me doing anything. Then I copied the motion code into my ACTIONS layer and put stop(); in the Hello Kitty object code. So, she doesn't jump all the time anymore, just when my mouse moves over her... but she only jumps once and that is the problem. I want her to keep jumping as long as my mouse is over her. Please HELP! THANKS!!!!

I won't be around much longer today, so on just a hunch I'd say if you comment out all of what you showed in your first posting, use what's below, and get rid of anything that might be stopping the kitty from jumping, it might work... though it might not...
HKITTY_mc.gotoAndStop(1);
HKITTY_mc.addEventListener(MouseEvent.ROLL_OVER, kittyJump);
function kittyJump(event:MouseEvent):void {

AS3 URL Request file not found

Hi
I just learned last night from Ned Murphy how to code a btn in AS3.
Trouble is, when testing the Dreamweaver frameset website, site name: URLRequest on the C drive with my default browser F12, I get a problem loading the page / file not found.
Here is the btn AS3 code.
btn1.addEventListener(MouseEvent.CLICK, btn1Click);
function btn1Click(evt:MouseEvent):void {
   var url:String = "C:\WebSites\FrameSets\URLRequest\mainFrame1.html";
   var req:URLRequest = new URLRequest(url);
   navigateToURL(req);
Just for comparison here is the AS3 btn code Ned copy pasted to my Thread last night.
btn1.addEventListener(MouseEvent.CLICK, btn1Click);
function btn1Click(evt:MouseEvent):void {
   var url:String = "http://www.awebsite.com/awebpage.html";
   var req:URLRequest = new URLRequest(url);
   navigateToURL(req);
What is it that is stopping my browser from directing to "C:\WebSites\FrameSets\URLRequest\mainFrame1.html";
Is it the var url:String?
Thanks for reading
Sabby76

Re Kglad Thank you
I copy pasted the URL into a browser and it junked to: file:///C:/WebSites/FrameSets/URLRequest,mainFrame1.html I don't know what is the correct name for file:/// probably just the O.S directories proxy? Using the file:/// in the btns function out-works perfectly. Now the rest of the websites frame set extensions directories will not pull up after the index for example: file:///C:/WebSites/FrameSets/URLRequest/index.html/mainFrame2.html I think a re-thread in the DW forum will be the next step, any clues?

Need help with LabVIEW code for motor control.

Hi,
My name is Sasi. I am a BME grad student working on my thesis topic of evaluating spine implants for low back pain. For this I am building a test machine that would apply pure moments to a spine specimen. I am using LabVIEW 8.5 to implement control of a brushless AC servo motor. My requirement is,
Step 1: Initialize the motor.
Step 2: Start moving it at a uniform RPM to the right (This RPM value too user can enter).
Step
3: While doin Step 2; simultaneously read torque cell data (Using DAQ
asst.). DAQ o/p is from 0 V to 10 V; 0 V being -10 Nm n
10 V being +10 Nm
Step 4: When Torque value reaches +10 Nm, i.e 10 V, the motor stops.
Step
5: From the position where motor stopped (i.e no need to reset to
initial position) Start moving in the opposite direction at the same
uniform RPM as in Step 2 while reading torque cell data.
Step 6: Once again when torque reaches -10 Nm, i.e. 0 V, the motor should stop.
Step 7: Repeat 'Step 2' to 'Step 6' 3 times.
Step 8: Reset motor postion.
Till now I have managed to get the motor to move forward n backward @ a desired vel, accl, n deceleration for 3 cycles. I am attaching my code. I am having problem inserting the code for reading DAQmx amidst all this. Can anyone help me out.
Thnks,
Sasi.

Hi Sasidhar,
I took a look at your problem and I think I have a workable solution for you. I definitely agree with Lynn's suggestion of using parallel loops. This will allow the DAQmx portion to run uninhibited by the motion portion, and vice versa. Plus, you only need to iterate the motion loop whenever the voltage level crosses a threshold. So, by iterating on the motion code in the same loop that you are iterating on DAQmx code, you are essentially wasting processor.
I created a VI that should do what you are wanting. I tested it out myself and it works great. You might have a tweak a few things to apply to your system (like motion board ID and DAQmx physical channel, etc.). I used two parallel loops and event-based programming. Basically the motion loop starts the motor spinning at the specified velocity. Once the motor is spinning, it waits for the DAQmx loop to tell it that the voltage value has crossed the threshold. When the voltage value exceeds the maximum threshold (which I set to a value slightly less than 10 to allow for jitter and saturation), the DAQmx loop signals the motion loop that it can finish its iteration. The motion loop stops the motion, reverses the direction, and starts the motion again. Once motion has started, it again waits for the DAQmx loop to tell it that a threshold has occurred, but this time, it is looking for a minimum threshold. I used "Occurrences" to implement the event-based programming in LabVIEW.
I have commented the code rather thouroughly, so hopefully the comments will answer any remaining questions. The benefit of using event-based programming for this is that you save processor time, and your motion is more closely synchonized with the DAQmx. Instead of iterating the motion loop as fast as you can, checking for updates each time, you just pause it, and wait for the other loop to tell you when to start up again. In the mean time, the processor doesn't have to worry about iterating that loop over and over again. Also, when the occurrence does occur, you catch it immediately, instead of having to wait until the next iteration. Thus, you are more closely synchronized with the DAQmx portion of the code.
I hope this will help you. Please post back if you have any questions about the code or its implementation. Good Luck!
