When accumulating objects on the stage, they start to disappear
I have three windows containing a total of 33 panes. The
panes each have a different graphic in them. I start with blank
panes and fill one pane at a time until all the panes appear.
Each pane is on a transparent gif with the same dimensions as
all the other gifs. I put the panes on the stage one at a time, in
separate layers and leave them there until the end of the show.
When I get part way through, it gets sluggish and objects
start disappearing. It works fine in the fla file but not the swf.
A rough working-version of the swf file is
here. This one
only works because I inserted intermediate "screen shots" to make
it work.
I am sorry that I cannot upload the source files at this time
(restriced access from office server) but can provide them later
today, if necessary.
Could it be that I have too many items that collect on the
stage?
Any guidance would be appreciated. Thanks in advance!
You can find the source code and SWF file
here.

Adding objects to the stage & acceessing stage properties - I'm a bit confused..
Hi,
I'm a little confused on two fronts regarding display
programming:
A. What the best way to add objects to the stage?
B. How to access stage properties.
I can do both of these when the project is an 'Action Script
Project', but I'm having trouble when it is a 'Flex Project' (e.g.
an MXML file). See the two attached files with questions included
in the comment to see exactly what I mean.
A. What the best way to add objects to the stage?
=====================================
In an action script project that extends Sprite I can just
call addChild()
In an MXML project I can add objects to the stage by first
adding them to a UIComponent, then adding that to the stage.
1. Is that the best way to do it?
In this doc:
http://livedocs.adobe.com/flex/3/html/help.html?content=05_Display_Programming_02.html
it says that
quote:
Each SWF file has an associated ActionScript class, known as
the main class of the SWF file. When Flash Player opens a SWF file
in an HTML page, Flash Player calls the constructor function for
that class and the instance that is created (which is always a type
of display object) is added as a child of the Stage object. The
main class of a SWF file always extends the Sprite class
2. why cant I just add a sprite object direct to the stage
without the UIComponent?
3. What is the 'main class', and how can i get access to it?
B. How to access stage properties.
=========================
In an action script project that extends Sprite I can just
call trace(stage.framerate)
But in an MXML file I cannot figure out how to access the
stage properties.
See the attached code for the things that I tried, but which
didnt work.
In the page:
http://www.actionscript.org/forums/showthread.php3?t=140655
It says
quote:
For stage access you have a couple of rules:
* natively, only display objects have inherent access to
stage
* display objects only have a valid reference to stage if
they're within the stage's display list (on the screen, after added
to it with addChild)
* The only display objects which immediately have access to
the stage before the use of addChild (in their constructor) are the
document/application class instance (root) and any instance from
the library placed on the timeline (not created with AS).
* Non-display object classes have to be passed or assigned a
reference to the stage from another object which already has access
to it - they cannot access it otherwise.
4. How do I access the stage properties in the MXML project?
5. I suspect this is related to the "main class", which I
dont yet understand - is it?
Sorry for the long post.
cheers

DropTarget check against all objects on the stage
Hey all,
Not sure the best way to do this. I have a class we will call DropActivity, here is the code
package com.activitycontrol
import com.activitycontrol.DropCheck;
public class DropActivity
// Constants:
// Public Properties:
// Private Properties:
private var _selectedClip:Object;
// Initialization:
public function DropActivity(/*selectedClip:Object*/)
// Public Methods:
public function set selectedClip(selectedClip:Object):void
_selectedClip = selectedClip;
public function stopDraggingMe():void
var dropCheck:DropCheck = new DropCheck();
//dropCheck.checkAgainst = dropTarget.name; ///***********
if (dropCheck.canBeDropped == true)
_selectedClip.stopDrag();
// Protected Methods:
when the stopDraggingMe() method is called from another object (code shown below) I need to see all the objects on the stage to see what objects on the stage my currently selected movie clip is over and assign it to the dropCheck.checkAgainst method (that will be checked against an array to see if it can in fact be dropped, if so set the canBeDropped value to true and therefor run the .stopDrag() ). I have read using root is not a good coding practice in AS 3.
call to the stopDraggingme() mehod.
private function setDown(event:MouseEvent):void
var droppedItem:DropActivity = new DropActivity();
droppedItem.selectedClip = this;
droppedItem.stopDraggingMe();No, I think I can use drop target, I just need to use it from the DropActivity class and not a document class. I just don't know how to use it from a non-document class.
"and you need to loop through all displayobjects to see which have a positive hitTest with your dropped object, correct?"
I am trying to say..... ok, what movie clip is currently under the one I have selected, the drop activity class knows what object I have selcted as it is in the selectedClip variable. so I need to find out what clip is under it ......... the light just came on!
answer duh......dropCheck.checkAgainst = _selectedClip.dropTarget.parent.name;
thanks a bunch kglad you have helped me out once again, you are the man. I might just have to buy you a beer one of these days. -
Positioning and temporarily hiding objects on the stage
(Flash newbie here - bear with me...)
I have two graphic objects on the stage overlapping each
other. The first I was able to position to the document boundaries
just fine. When adding the second object, however, the first object
covers the boundaries so I cannot see them to align the second
object.
The question: Is it possible to temporarily hide an object on
the stage so I can see the stage boundaries to position another? I
don't see any options that will allow me to do this.
Thx!there is a little colored square on each layer, to the right
of the layer name, click that square on the layer that the first
object resides, it will then just show an outline. click it again
to bring it back. You can also click the first 'dot' next to the
layer name, it will completely hide the contents of that
layer. -
Can't edit objects on the stage
Hi,
I'm stumped helping my colleague on the issue below so I'm logging this question.
Issue: My colleague is trying to edit a slide but can't edit any of the objects on the stage. However, it works fine when I open the same project on my machine. Is there a setting on her machine that's causing the issue?
In the screenshot below, check out Slide 2 (selected) notice how:
in the thumbnail there are multiple objects (white image on the left, blue text caption in the center) on the slide.
in the timeline multiple objects are available and selectable. All are set to be visible (the little "eye" isn't switched to off).
when you look at the stage, the only things that we see are the background and a single button.
The objects also appear fine in Preview.
On the stage, can "phatomly" select objects, but she can't change the characteristics of them (e.g., change text in a text caption, resize object, move object).
Screenshot:
OS: Windows 7
Captivate: v5.5 (running as Administrator)
Background info:
This project was initially created in an older Captivate version (4.0 or 5.0) and is now being edited/updated.
Last week, my colleague was trying to edit the same project (using v5.0). When she clicked play on the timeline, her audio wouldn't play. When she watched the Preview or tried to edit the audio, the audio would play just fine. Also, on my machine (running v5.5) it worked fine. This prompted me to suggest that she update to v5.5. Alas, it seems this fixed the audio issue, only to create this video issue.
Thanks,
- DinoHere's a bigger/better quality image. I hope it helps.
Notice how the Text Caption is selected in the timeline and it's properties are visible on the right. Yet the item itself is nowhere to be seen on the stage. Also, now it seems to have disappeared from the thumbnail. -
Hide objects outside the stage
Hi there!
I have recently downloaded a sample FLA file and I see the stage is FIXED on top-left side of the flash screen and objects outside the stage does not appear on screen (Like a mask, but there is no mask layer).
And when I create a new file the stage appears in middle of the screen and objects outside the stage are not masked.
Would you please help me what should I do in this case?
(I always use a very big White layer in top of all other layers, to cover out of stage, OR use a mask layer)
Regards,
AliHi!
Sorry if my question was not clear. here is the link (adobe TV):
http://downloads.tv.adobe.com/2012-00-24/WebChallenge_FL_3.zip
I have uploaded that single FLA file to the address below :
http://www.howallah.com/Mobile.fla
To simplify my question, each flash scene is indeed divided into 3 sections based on colors (white, light grey, dark grey) as marked below :
(the Zoom is 20% to cover them all).
Section 1. is called Stage (I know)
Section 2. it expands automatically as you move an object outside the stage (image, movieclip etc.) and it works like a mask (I dont know the name of this section)
Section 3. is something like "out of Scene" (I don't know the name of this section as well)
What I want to do is sort of FITTING Section 1 (Stage) to Section 2.
Exactly like the FLA sample file above.
What is that good for?? to help me only see the stuff INSIDE the stage, without any need to make a mask layer or a LARGE white layer above all layers etc.!
Anybody knows what I am talking about and having a clue please?
Regards,
Ali -

I just bought a new laptop and my ipod nano will not stay connected to my computer. When I first connect the ipod it starts to sync on my ipod but not on itunes. The ipod is initially connected to my computer, I can see it when I look on devices in my computer. However, when it finishes syncing it is no longer detected to my computer. I cannot transfer any of my songs to my new laptop because of this. I have tried to reinstall itunes, reset my ipod and use a different port. None of these things worked. Any ideas?

Lately I've been importing photos from my iPhone to iPhoto and when I attempt to edit them they seem to disappear. Some reappper as a photo stream pic (some as the edited version and some not). But they no longer appear as a recent import. Lots more happens and I'm wondering if it's because I have a 5-year old Mac book or iPhoto is having issues. I'm not happy with disappearing photos especially after I've deleted them from my iphone after importing them to my macbook.
Has anyone experienced similar difficulties and what can I do?Remember: we cannot see your machine. There are 9 different versions of iPhoto and they run on 8 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS. So to get help you need to give as much information as you can. Basic things like :
- What version of iPhoto.
- What version of the Operating System.
- Details. As full a description of the problem as you can. For instance: 'iPhoto won't export' is best explained by describing how you are trying to export, and so on.
- History: Is this going on long? Has anything been installed or deleted?
- Are there error messages?
- What steps have you tried already to solve the issue.
- Anything unusual about your set up? Or how you use iPhoto?
Anything else you can think of that might help someone understand the problem you have. -

Deleting objects from the stage
Hi all,
I've got some items on my stage that I'm removing with
RemoveChild(). The items no longer show, however, as stated in
LiveDocs, the item is not actually destroyed. This means any
bindings/listeners created by that object are still in existence
and are creating errors (Specifically, I'm getting "The supplied
DisplayObject must be a child of the
caller").
LiveDocs mentions that if I want to actually delete an object
from the stage entirely, I should use the "delete operator", but
for the life of me, I can not find any documentation on the
existence of such an operator. Any advice would be much
appreciated.
-HobIt IS ridiculously hard to find. Searcing Live Docs for
delete oprator will turn up a slew of hits, but which is the right
one?
This is from old docs, but it is still valid:

Duplicating the motion of an object across the stage
Suppose I have a single moving object on the stage is it possible to replicate the object at regular intervals across the stage WITH the motion?
Is this motion achieved through actionscript or is it a tween on the stage? If this is a tween on the main timeline on the stage, then you could make that animation a movieClip and play the movieClip at an interval, maybe using a timer. If the animation is achieved using actionscript then write the animation as a function and call the function at an interval, again, possibly using a timer.

Problem removing Objects from the stage in Flash CS4 (AS3.0)
I have a problem with this code:
this.addEventListener(Event.ENTER_FRAME, vanish);
function vanish(event:Event):void{
if(character_mc.hitTestObject(vanish_mc)){
vanish_mc.parent.removeChild(vanish_mc);
There are two overlapping objects on my stage: character_mc and vanish_mc.
As soon as i start the scene[Ctrl+Enter] vanish_mc is VISUALLY removed. But the code still sees a collision somehow. How can i Entirely remove the object vanish_mc?
Thank you for help and advice.Ah I think the problem is what my problem not which I proposed, my bad I was trying to keep it simple.
the remove code in my problem actually looks like this:
if(character_mc.hitTestObject(this["dollar_mc_"+String(i)])){
removeChild(this["dollar_mc_"+String(i)]);
I wanted it to be that way so I could add infinite "dollar_mc_" ' s without writing myself to death with code and or getting confused.
Imagine it like a game where a character it picking up dollars, which would disappear once they intersect.
And that exactly is what gives me that argument.
Do you know a way i could write this code, or do you suggest to leave it that way...because it does run and work im just getting this argument while debugging.
Thank you for all the help~
