Help with smooth scrolling (masked movie clip)

Ok, I really need help here, and I'll be very grateful for
help before Monday.
Someone has made a movie with a different set of text on each
frame, the text goes out of the viewable area.
I have been asked to make these frames appear in a pop-up on
another flash and be scrollable.
i thought this would be easy...just cut and paste them into a
movie clip, then using a mask to hide the rest of the text.
However, it is going painstakingly slow.
Seems to be a performance issue, but it might be my code.
Any help with the code, or optimisation elsewhere would be
helpfully.
Heres a simplified version of the flash;
www.darkflame.co.uk/flashwork/Flash_popuptest.fla
Code for the scrolling;
_global.MoveUp = function(text) {
_root.ITproduct.IT_productlist._y =
_root.ITproduct.IT_productlist._y+6;
updateAfterEvent();
//trace('press');
Called and stopped by;
on (press){
//this._parent.IT_productlist._y =
this._parent.IT_productlist._y +10;
//_global.scrollon = "yes";
clearInterval(IntervalID);
IntervalID = setInterval(MoveUp,100);
updateAfterEvent()
//updateAfterEvent();
//MoveUp();
//scroll on
on (release) {
//this._parent.IT_productlist._y =
this._parent.IT_productlist._y +10;
clearInterval(IntervalID);
updateAfterEvent();
//scroll off
which is linked to a button.
I dont know if this is a actionscript problem, or the way the
page is made, or both.
Any help would be appreciated.
Thanks in advance,
Thomas Wrobel

you have extraneous graphics on-stage that are slowing the
scrolling (and even causing problems in the authoring environment).
here's your file with those graphics removed:

Need help with smooth scrolling of a sprite

Hi All,
Something that i have had many problems over the years with
is creating the same nice smooth scrolling effect that i see on
many sites (my scrolling always appears jerky in AS2 even when done
on a movieClip with a high framerate - with onEnterFrame updates).
At the moment i am building my first AS3 site, and want to
use it as an opportunity to "do things right".
So far i have a very simple setup that is scrolling a sprite
that contains a series of loaded images based on the position of a
scrollbar. As one would expect from something this simple - it is
rather jerky.
I tried a number of variations of using a Tween to do the
scroll, and kill/update that tween when the mouse moves again.
However in all cases the results were not good (multiple tweens
seemed to still be active - so killing the tween wasn't working).
So clearly i am doing something wrong.
I have searched extensively, but have not come across any
examples that seem appropriate (some predefined components - but
that does not help me understand the fundamentals) . I have seen
some examples that register a timer, and manually calculate the
offset for each frame, is this the correct approach?
Below is my existing simple (jerky) implementation.
All help to understand how to make this scrolling smooth
would be hugely appreciated.
One more thing to add incase it is relevant, is that the
contents of the Sprite are a series of jpg images loaded with the
Loader class (although i plan on switching to using the BulkLoader
class created by a developer in the AS3 community).

nope. the approach for the smoothest tween would be to:
1. initialize your parameters
2. create your timer.
3. add your timer's listener method when needed (when your
slider is clicked).
4. in your timer's listener function repeatedly poll the
slider's position and update your sprite using the parameters
determined in 1.
5. remove your listener when the slider is released.

Deadline: 22 May 08H00 Help ME Please Scrolling a movie clip from the Centre

Hi
It has been a while since I have been here I am in need for
some serious help, I am so frustrated.
What I want to do is pretty simple, I am building a DJ
website and the navigation is a pitch controller, similar to what
they have on a mixing board anyway, when you drag the pitch
controller I need the movie clip symbol to scroll either up and
down, so technically the pitch controller will have to start from
the center, but I have no idea what I am doing.
I have been going through tutorials for 15 hours but all they
show you is how to create a normal scroller that starts at the top
and srolls down. I am in desprite need as I have a deadline to meet
for tomorrow morning. HELP

ok this is the code I got from a tutorial that i was woking
from, but I dont really understand it in detail what I do know is I
dont need the arror buttons in this code becuase all I need is a
the scroller.
scrolling = function () {
var scrollHeight:Number = scrollTrack._height;

Dragging masked movie clips

Can anyone point me in the right direction?
I've been playing around with making a draggable movie clip.
This movie clip appears within a container, holder_mc, which is
masked by a mask layer to control what is seen. I can drag
holder_mc around the screen, but the mask does not move with it.
When I hit the movie_btn, I cannot see my VideoPlayer.swf file. If
I do not drag holder_mc anywhere, and just press my movie_btn, I
cannot drag my swf file. Is there an easy way to have the mask and
holder_mc drag together, and have drag functionality even after my
swf is playing?
Here is what I'm using:
movie_btn.onRelease = function (){
holder_mc.loadMovie ("VideoPlayer.swf");
holder_mc.onPress = function(){
this.startDrag(false);
holder_mc.onRelease = function(){
stopDrag();
Thanks for any help.

Couple of ways... simple enter_frame, or enter_frame TweenLite
addEventListener(Event.ENTER_FRAME, updateReflection, false, 0, true);
function updateReflection(e:Event):void
     refClip.x = mouseX;
     refClip.y = mouseY;
or using TweenLite to give it a little softer motion:
function updateReflection(e:Event):void
    TweenLite.to(refClip, .5, {x:mouseX, y:mouseY});

How do you horizontal scroll a movie clip?

Can anyone suggest any resources for horizontal (left to right) scrolling a movieClip? I want to be able to scroll through a movie clip that has pictures in it. I can't find any good ones that explain the code. FYI, I do not want the user to use a scroll bar to scroll through. They should be able to touch the screen (on the movieClip) and scroll left or right. I looked at the ThrowPops plugin example on Greensock's website but the code is not explained very well. So I need a basic description of how to scroll a movie clip.

Question about scrolling and Movie Clips Loaded from the Library

I hope I am posting this in the right forum.
Ok, I'm using actionscript 2.0, and I am trying to make a scrolling image gallery. I have a movie clip with three layers. the first contains a movie clip used as a scroll bar. The second is a mask used to hide the overflow content, and the third contains movie clip thumbnails. when I click one of the thumbnails, it loads a symbol containing a larger version of the picture over top of the thumbnails on the same layer. My problem is, the large image is added at the very top of the movie clip, even when it is scrolled out of sight. I want it to appear in sight, so the user doesn't have to scroll all the way back up to the top to see it. This is annoying and confusing. Is there a way to do this?
Here is the code I used to create the scroll effect (there is actually a whole lot more to the code but it is very long, so I am not adding it now. I will if it is needed though)
(Oh, and there is no text involved in this. I just got this code off a tutorial and I haven't changed the variable names yet)
    var scrollUpper:Number = 58;
    var scrollLower:Number = 309;
    var textLower:Number = 60;
    var textUpper:Number = -179;
    var scrollRange:Number = scrollLower - scrollUpper;
    var textRange:Number = textLower - textUpper;
    var startY:Number = imagesHolder_mc.thumbs_mc._y;
    function scroll(){
       var moved:Number = imagesHolder_mc.scroller_mc._y - scrollUpper;
       var pctMoved:Number = moved/scrollRange;
       var textMove:Number = pctMoved*textRange;
       imagesHolder_mc.thumbs_mc._y = textLower - textMove;
    imagesHolder_mc.scroller_mc.onPress = function(){
       this.startDrag(false,this._x,scrollUpper,this._x,scrollLower);
       this.onMouseMove = scroll;
    imagesHolder_mc.scroller_mc.onRelease = scroller_mc.onReleaseOutside = function(){
       this.stopDrag();
       this.onMouseMove = null}

Thanks for your reply. I'll try to explain it better. I have a long, vertically scrolling movie clip. This movie clip contains lots of thumbnails. When I click a thumbnail, the full sized image is loaded from the library and displayed within the same movie clip. when I click the full size movie clip, it disappears again, and I can click another thumbnail to display another full size image. So I'm not just adding more and more stuff to the gallery if that's what you were thinking. I'm just clicking thumbnails to display the full size image so I can look at it, closing it, and moving on.
But the full sized image is fixed at the very top of the scrolling movie clip, so if I click a thumbnail at the very bottom, I have to scroll all the way back up to the top to see the full size image. I just want the full size image to appear on screen no matter how far down I have scrolled to click a thumbnail.
I made my basic gallery useing this tutorial:
http://flashexplained.com/actionscript/making-the-ultimate-dynamic-image-gallery-in-flash- 8/
if you want to take a look at that, to get an idea of what I'm talking about.
Now I'm just trying to add some scrolling functionality, which wasn't included, but I don't really understand actionscript well enough to do this easily on my own.
Sorry for the long reply. I hope this is clearer.

Please help! first website! movie clip placed on main timeline wont play!

Hi! if any one could please help me it would be greatly
appreciated!
So im trying to make my first website in flash and ive ran
into a problem. I have the main movie, my main time line. I have a
few animations going on in this that were all created in that main
time line. those work fine. however, i created two new movie clips
(still inside the same .fla file) and animated them with thier own
time line. I then thought you could just drag and drop these movie
clips onto your main time line and they would play inside the
movie. but when i press ctrl + enter, the dont play!
here are some points of intrest.
my main movie (the main time line) is 130 frames.
the movie clips i made inside the same .fla file are between
400 and 600 frames.
i placed both new movie clips on the 130th frame in the time
line with their own layers.
also there is a layer for actions on the 130th that has
stop();
i thought that maybe the time line had to be as long as those
movie clips i created and so i extended it but they still didnt
play.
im thinking action script is involved? please help me im
getting pretty frustrated and im sure there is something simple to
achieve this.
here is a link where you can download the source files im
using. if you open the file the two movie clips i created are
called front two and front one and are layers with the same name.
this board wont let me fully post my link cause the last word
in it is s*h*i*t* so youll have to type it in your browser. its
http://public.me.com/matts*h*i*t*
(just remove the asterisks)
also i noticed that my file is huge. i used photoshop to
create everything and them imported it into flash. is there a way i
can reduce this size?
thank you sooo much! please help!
-Matt

Hey Matt,
I'll take a look at your file, but as a general rule, a
movieclip's timeline plays automatically when it is first
instantiated. Instatiated means its first frame where "it exists"
on the timeline that contains it. So the layer that holds your
movieclip animation, needs to extend the length of the timeline you
want that movieclip to "exist". Other than that rule, the frames
don't NEED to match the frames inside said movieclip.
So, if movieclips play automatically, and yours isn't, there
must be something either stopping the movieclips timeline, or your
movieclip isn't existing on the timeline because the layer that
holds it, doesn't have keyframes the length you need it to.
Yeah optimizing your sprites (2d graphical elements), and
using vector when you need to (if you don't know the difference
between raster and vector, google it) will significantly lower your
outputted .swf file size.
Edit: After looking at your file, your movieclips are not
playing (well, they're technically playing, just not showing up)
because your masker layer has multiple objects on it. A masker
layer (not to be confused with the maskee layer, the layer being
masked) needs to have only one object on it, or else you break the
mask. The grey border of your mask movieclip needs to be deleted
before your animation will play.

Need help with video-scroll

Hello,
I need some help with a project. What I eventually want is that a webcam controls the mouse position and the mouse position
controls a video. But first I would like the part where the mouse position controls the video.
So if the mouse is on the left on your screen the video will be at the first frame and when you move you're mouse to
the right the video will play accordingly to the movement. and stop when the mouse is all the way to the right.
Effectivly the mouse scrolles through the video. It only needs to be on the x-axis.
I'm not that formilliar with flash so any help would be great
Thx!

Help with a scrolling flash panel

Hello, Ive used the excellent tutorial to create a scrolling thumb panel (http://library.creativecow.net/articles/brimelow_lee/scrolling_thumbnail_panel/video-tutor ial.php)
It works brilliantly and I have movie thumbs linking to a flash player. It all works fine, what Im needing help with is to change the scrolling.
At current it scrolls up and down according to where I have set the 'line', I would like it to scroll up and down near the top and the bottom, rather than all the time (effectively creating a dead zone in the middle). I cant figure out how to change the code to get this to behave as required.
Please Help!
Below is the code used:
panel.onRollOver = panelOver;
function panelOver() {
this.onEnterFrame = scrollPanel;
delete this.onRollOver;
var b = stroke.getBounds(_root);
function scrollPanel() {
if(_ymouseb.yMax || _xmouseb.xMax) {
this.onRollOver = panelOver;
delete this.onEnterFrame;
if(panel._y >= 278) {   //FIRST BUTTON 'Y' POSITION
panel._y = 278;
if(panel._y <= -177) { //CHANGE '229' TO THE 'Y' POSITION OF THE LAST BUTTON IN THE 'PANEL' MOVIE, POSITIONED VISIBLE WITHIN THE BOARDERS.
panel._y = -177;
var ydist = _ymouse - 251; //POSITION ON STAGE OF UP/DOWN SCROLLING 'LINE'
panel._y += -ydist / 150;   //SPEED OF SCROLLING (LOWER = HIGHER)

use:
panel.onRollOver = panelOver;
function panelOver() {
this.onEnterFrame = scrollPanel;
delete this.onRollOver;
var b = stroke.getBounds(_root);
function scrollPanel() {
if(_ymouseb.yMax || _xmouseb.xMax) {
this.onRollOver = panelOver;
delete this.onEnterFrame;
if(panel._y >= 278) {   //FIRST BUTTON 'Y' POSITION
panel._y = 278;
if(panel._y <= -177) { //CHANGE '229' TO THE 'Y' POSITION OF THE LAST BUTTON IN THE 'PANEL' MOVIE, POSITIONED VISIBLE WITHIN THE BOARDERS.
panel._y = -177;
var ydist = _ymouse - 251; //POSITION ON STAGE OF UP/DOWN SCROLLING 'LINE'
if(_ymouse>lowerY || _ymouse<upperY){
if((_ymouse>lowerY){
ydist=_ymouse-lowerY; // define lowerY
} else {
ydist=_ymouse-upperY; // define upperY
} else {
ydist=0;
panel._y += -ydist / 150;   //SPEED OF SCROLLING (LOWER = HIGHER)

Hi, i am a bit of a newbie at AS & need some help applying it to a movie clip button

I have created a movie clip button but am stuck with the actionscript. I have created the rollover and rollout for this movie clip button but i want it to do 2 things after this i want it to go and stop on the first frame of a movieclip which has my content on it called portfoliogallery_mc (which is also the same instance name for it) when you then click the button i want it to go and play frame 11 of that movie clip portfolio gallery_mc.
Here is my current actionscript i HAVE Flash 8 on my comp that i am currently using.
Please note my actions are on a layer called actions and not on the movieclip button itself.
nxtimagetwo_mc (is the movie clip button/instance of mc)
THE CODE I HAVE USED
this.nxtimagetwo_mc.onRollOver = function() {
nxtimagetwo_mc.gotoAndPlay("_over");
this.nxtimagetwo_mc.onRollOut = function() {
nxtimagetwo_mc.gotoAndPlay("_out");
portfoliogallery_mc.gotoAndStop(1);
portfoliogallery_mc.gotoAndPlay(11);
currently it is playing to frame 11 not stopping at frame 1 and stops on frame 20 where i have a stop action. I also have a stop action on frame 1 of that movie clip.
What I want it to do is first stop at frame 1 of that movie clip and when the button is clicked again to go and play frame 11 of that same movie clip.
Basically what i want the mc button to do is 2 things automatically stop the mc for the first content and when button is clicked let the content fad out and play to where the next stop action is set to in the Movie Clip.
Nothing to with the above www.rsquareme.co.uk is my current portfolio website if you would like to check it out it is not fully complete yet.

it doens't make sense to execute:
portfoliogallery_mc.gotoAndStop(1);
portfoliogallery_mc.gotoAndPlay(11);
only the 2nd line of code will be effected.
i know you want to control 2 movieclips. what are the instance names of the two movieclips and what do you want to occur in each of those movieclips.
or, do you want to control 1 movieclip and have it play a certain sequence of frames followed by another sequence of frames?

Need help with AS3 to play movies

Here is my what I'm working with: Flash CS3, AS3. I have 4
buttons and 4 movies (each button will be asigned to play one of
the 4 movies).
Not sure if this is the best layout but here is what's
included in my file. I have an Actions layer, 4 buttons (on 4
different layers), 4 embedded movies (on 4 different layers...all
about 5-8 seconds long). I'm sure this is simple but figuring out
the code for AS3 is like learning Chinese....I need major help with
this.
Lets say that my buttons have instance names like button1,
button2, button3, button4, and my movies have instance names like
movie1, movie2, movie3 and movie4. Here's the catch. I don't want
the movies viewable (or seen) until the user selects one of the
buttons. So if the user selects button1 the movie will appear (next
to the button without any contols...just a movie with a border) and
play. If the user hovers off or moves the mouse off the button, I'd
like for the movie to disappear.
Can someone please give me the the code needed so that when I
select button1 that it will play movie1, button2 w/ movie2....and
so on.
Thanks for your help!

Here is the link to the fla file.
http://joshhicks.com/flash/flashfile.html
I updated the link to the latest swf
http://joshhicks.com/flash/del2.html
I added stop(); to the 1st frame of each moive and this fixed
the movies from playing in the background unseen. If you can help
me with one last question...then the file will be complete. As of
now when you select one of the movies, it plays once thru and
starts back at frame one (loops) which is the way I want it to
play. But if you hover off one of the buttons while the movie plays
(lets say when the movie is showing the number 2) when you go back
to view the same movie, it will start where you left off (it will
start on the fram showing 2 and not 1). How can this be set up to
play from the beginning of each movie everytime you happen to go
back and click on the button? Thanks

Problems with button inside draggable movie clip

I am building a click through presentation that has some small text in it. To maintain the design and allow for readability, I have added a zoom feature.
Here is the structure of the movie,
Stage - contains pages movie clip and forward/reverse click buttons for changing pages
pages_mc - contains 24 frames, one page per frame and buttons
There is a button at the _root level that uses a tweener to scale the pages_mc up to 170%. When this is clicked, it allows the pages to be dragged around the screen so you can look at different sections. When you click the button again, it returns the pages back to their original size stops drag.
My problem is, on the pages, there are buttons with links to external sites. Once startDrag has been invoked, I cannot touch the buttons inside the movie clip. Is there a way to make these buttons work?
I need the finished quickly so any assistance is welcome.
Code below
magUp_btn.onRelease = function() {
this._visible = false;
TweenLite.to(pages_mc, .25, {_x:-250, _y:-193, _xscale:170, _yscale:170});
TweenLite.to(magUp_mc, .75, {_alpha:0});
TweenLite.to(magDown_mc, .75, {_alpha:25});
magDown_btn._visible = true;
pages_mc.onPress = function(){
this.startDrag();
pages_mc.onRelease = function(){
this.stopDrag();
pages_mc.onReleaseOutside = function(){
this.stopDrag();
pages_mc.useHandCursor = false;
TweenLite.to(instr_mc, 1, {_alpha:100});
magDown_btn.onRelease = function() {
TweenLite.to(pages_mc, .25, {_x:0, _y:0, _xscale:100, _yscale:100});
TweenLite.to(magUp_mc, .75, {_alpha:25});
TweenLite.to(magDown_mc, .75, {_alpha:0});
this._visible = false;
magUp_btn._visible = true;
pages_mc.onPress = function(){
this.stopDrag();
TweenLite.to(instr_mc, 1, {_alpha:0});
I don't know how to turn drag off when I zoom out without using the onPress command, but I know that this is probably what is getting in the way of the button working?
Thanks!

One option is to make the background of the pages be the draggable parts rather than the movieclips that contain the pages and buttons. That way, the buttons could be atop the background and not have their access blocked.
Instead of coding the pages_mc, you would essentially have the background coded for the drag...
pages_mc.bkgnd.onPress = function(){
startDrag(this._parent);

Problem with accessing dynamically created movie clips, returns null...

Hopefully this is a stupid question with an easy answer, if my code is straight forward enough.
I am using this snippet of code to create menu items, and then use the jCount variable below to give the clips an index number, like so (which seems to be working just fine):
for(var j:Number=0;j<xmlSubMenuLength;j++){
    var mcSubMenuItem:mcSubMenu=new mcSubMenu();
    addChild(mcSubMenuItem);
    jCount++;
    mcSubMenuItem.name = "mcSubMenuItem" + jCount;
    //traces out names correctly
    trace ("---------------------------------jCount NAME = "+ mcSubMenuItem.name);
    mcSubMenuItem.x=mcMenuHolder.x+20;
    mcSubMenuItem.y =mcMenuHolder.y;
    mcSubMenuItem.y+= nextBtnY;
    nextBtnY+=subtopicSpace;
    global_subi.text = String(jCount); //i see the proper count of 10 in the text field
However, when I try to access the clips using this snippet:
for(var j:Number=0;j<Number(global_subi.text);j++)//
trace("GLOBAL SUBI = "+ String(global_subi.text)); //traces out 10, which it should
var scSubMenuItem:String = "mcSubMenuItem" + j;
var scSubContent:Object = this.getChildByName(scSubMenuItem);
trace(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>scSubContent:Object = "+ scSubContent); //returns null!
My last trace statement returns null. Can anyone see my error, or explain why I can't access my clips after they have been created?
Thank you muchly,

Hi kglad,
Thanks for the response.
"it's not clear from the shown code that jCount is initialized." - I've posted the relevant code below, which shows that I'm initializing jCount.
"and it's not clear why you don't use j instead of jCount in that for-loop" - j is used as loop for creating the subtopic movie clips within the i for-loop. So, for each topic in i for-loop, create a group of suptopics using the j for-loop. The j for-loop re-initiates j every time the length of the subtopics is reached(if that makes any sense) - i.e. topic1>subtopic 1,2,3,4 : topic2>subtopic>1,2 : topic3>subtopic1,2,3,4
jCount is used to keep a running count of the total number of subtopcs created - i.e. per the example above, jCount will display 10.
var topicSpace:uint=button_mc.height;
var subtopicSpace:uint = button_mc.height;
var nextBtnY:uint = 0;//whatever;
var jCount:Number = 0;
function createXMLMenu(menuLength:Number,itemName:XMLList):void{
     var navItemText:XMLList = itemName;
      for(var i:Number=0;i<menuLength;i++)
           var mcMenuItem:mcMenu=new mcMenu();
           addChild(mcMenuItem);
           mcMenuItem.btnTxt.htmlText = i+1 +". " +navItemText[i];
           mcMenuItem.ivar = i;
           mcMenuItem.name = "mcMenuItem" + i;
           mcMenuItem.x=mcMenuHolder.x;
           mcMenuItem.y =mcMenuHolder.y;
          //kglad's addition
           mcMenuItem.y+= nextBtnY;
           nextBtnY+=topicSpace;
           var subVar:Number = i;//mcMenuItem.ivar
           //Submenu content
           var xmlSubMenuLength:Number = xml.sim.bodyText.page[i].subpage.length()
           var menuItemAttachment:MovieClip = MovieClip(mcMenuItem);
           for(var j:Number=0;j<xmlSubMenuLength;j++)
                 var xmlSubPageNumber:XMLList = xml.sim.bodyText.page[subVar].subpage;
                 var subNavLinkNumber:Number = xmlSubPageNumber[j];
                 var subTitleText:String = xml.sim.bodyText.page[subVar].subpage.subNavItem[j];
                 var mcSubMenuItem:mcSubMenu=new mcSubMenu();
                 trace("mcSubMenuItem.ivar = "+ j+1);
                 var mc2Attach2:MovieClip = MovieClip(menuItemAttachment);
                 mcSubMenuItem.btnTxt.htmlText = j+1 +". " +subTitleText;
                 mcSubMenuItem.ivar = Number(subVar);
                 mcSubMenuItem.jvar = Number(j);
                 addChild(mcSubMenuItem);
                 jCount++;
                 mcSubMenuItem.name = "mcSubMenuItem" + jCount;
                 trace ("---------------------------------jCount NAME = "+ mcSubMenuItem.name);
                 mcSubMenuItem.x=mcMenuHolder.x+20;
                 mcSubMenuItem.y =mcMenuHolder.y;
                 //kglad's addition
                 mcSubMenuItem.y+= nextBtnY;
                 nextBtnY+=subtopicSpace;
                 global_subi.text = String(jCount);
            mcSubMenuItem.lExtend.visible = false;
global_i.text = String(i);
Then I try to access the clips like so:
-The first for-loop access the topic movie clips, no problem, and traces out scContent correctly.
-The second for-loop traces out null everytime, when I would expect it to be tracing out the names of the subtopic movie clips.
function accessClips(){
     //This will access the topic movie clips
     for(var i:Number=0;i<Number(global_i.text);i++)
           var scMenuItem:String = "mcMenuItem" + i;
           var scContent:Object = this.getChildByName(scMenuItem);
           trace(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>scContent:Object = "+ scContent);
     //This is supposed to access the subtopic movie clips
     for(var j:Number=0;j<Number(global_subi.text);j++)//
           var scSubMenuItem:String = "mcSubMenuItem" + j;
           var scSubContent:Object = this.getChildByName(scSubMenuItem);
           trace(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>scSubContent:Object = "+ scSubContent);
Hope this makes sense, Chipleh confused. If the code is not clear enough, let me know and I'll try to further clarify.
Thanks again,

Mask - movie clip loaded from .swf

Hi!
I have made an application where a movie clip (map_mc) is
masked by another movie_clip (map_window_mc:
map_mc.setMask("map_window_mc");
This works fine until I try to load an "external" .swf into
map_mc:
map_mc.loadMovie("Testmap.swf");
Then the mask does not work anymore......
Any suggestions?
(The testmap.swf is also displaced from map_mc.........)
I use Flash 2004 MX pro

terjem,

Depending on the approach you're using, there may not even
be an event
handler when the external SWF loads. If you're using the
MovieClipLoader
class, there will be. If you're using a
MovieClip.onEnterFrame loop, there
won't be.

Okay.

Okay. So far, so good. When bytes loaded is greater than
zero and
greater than or equal to bytes total, you'll know the
external SWF has fully
loaded. You'll know, because the "Loading complete!" trace
will be visible
in your Output panel. Well, that means the place in this
script that
represents "where to put additional code" is right were your
trace()
functions are. Not in the "else" clause, but the first one
this.onEnterFrame = function() {
if (
map_mc.getBytesLoaded() > 0 &&
map_mc.getBytesLoaded() >= map_mc.getBytesTotal()
trace("Loading complete!");
trace("File width: " + map_mc._width);
[delete these trace() functions, if you like]
[add your masking code here]
delete this.onEnterFrame;
// etc.
> The code below does not work (the positioning of the

Your problem may be right here ...
> map_mc.setMask("map_window_mc");
... because "map_window_mc" is in quotes. Yes, the
ActionScript Language
Reference says the parameter of setMask() may be a string,
but leave the
quotes out and see what happens. In any case,

Hi and Welcome to the Community!
Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
Best!
