ActionScript 3.0 :: Flash Check Container And AddChild If Empty
Apr 7, 2011
I have a button on stage which has a child menu movieclip and that movieclip has three submenu button children.On each of these 3rd level buttons an event listener draws a new container on the stage and adds a new movieClip holding various info.This all works nicely, but I cannot work out a way to get an eventListener on the menu buttons to check if the container already exists so I can then stop the button repeating the add container function. So, at the moment you can repeatedly hit any of these menu buttons and they will just continue to add info movieClip children.I've tried some nice Boolean commands that should work, but I think it's the nesting of the children/relationships that are not allowing me to get this to work.So, basically for arguments sake, let's say I only have one of each item... here's the nesting of children:[code]

I have a code to erase a masked movieclip. I would like to know how I can check if the whole movieclip is been erased. So I thought I had to check if the BitmapData is empty. How can I check if every pixel of the movieclip has been erased?
if (erasableBitmapData = empty){
trace("empty")
} var lineSize:Number=40;
var doDraw:Boolean=false;
var resumeDrawing:Boolean=false;

checking an XML file for a specific node.
Example:
<vid
flv="videoName"
thumb="thumbnail.jpg"
title="Video Title"
[code]....
The first vid node contains a path to a logo graphic, I then need to check in my ActionScript if there is a logo there or not, and to do something if there is(display the logo) I can trace out the logo path so I thought I could run a simple if/else to check if there is anything in that node and if so to do something:
private function thumbOver(e:MouseEvent = null):void
{
trace("
");
[code]....
Now I've tried everything, but it will always trace out "Does have a logo" no matter what I do. I tried:
if (tabData[tabID].video[e.target.id].@logo == "")
if (tabData[tabID].video[e.target.id].@logo == null)
However I get the same results?

I'm coding this minigame implementation where a sprite traverses tiles on a screen, and when he's done traversing a tile, the tile "disappears" (its alpha decreases and it becomes a "wall" the player can not move onto). Now, simple enough. Make use of a traversing and traversed boolean arrays to store if a tile is currently being traversed, or if it isn't, but it has been traversed. So, if traversing == 0 and traversed == 1, make the tile "disappear". However, and here's the weird part, if I just set the alpha to, say, 0.5 in this if statement, it sets the alpha on just the tile I traversed, whereas if I try to make it part of the wall as well (in the same if), every tile except the one I've traversed to becomes a wall.
Here's part of the code (it happens in the enterFrame game loop):
Code:
const NUM_TILES = 15;
//Add MC for all the tiles
var tiles = new MovieClip();
addChildAt(tiles,5);

I'm working with a window scroller component, where the dynamically loaded scrolling content has buttons that load attach mc's to a clip holder in front of the window scroller. To do this I use this bit of code, which works fine:
Code:
calendarPagesBtn_mc.onRelease = function(){
_level0.slideHolder_mc.attachMovie("calendarPages", "calendarPages", _level0.slideHolder_mc.getNextHighestDepth());
this.enabled = false;
};
The "this.enabled=false" is to deactivate the button in the scroll content, otherwise it will still be active in the background. So far so good.
What I need to do, once the "close" button on the attached mc is clicked, is re-enable the button. I'm thinking the way is to check if the attached mc has been unloaded, which I'm trying to do with this:
Code:
if (!_level0.slideHolder_mc.content)
this.calendarPagesBtn_mc.enabled = true;

I'm trying to make my site Fluid but the problem is my menu is created with a for loop and addChild. These childs are pushed inside an array and this array is within an empty movieClip. But when I try to place this menu at the center [ ((stage.stagewidth / 2) - (menuGroup.width / 2)) for X, you know the drill for Y] it won't get centered because with a few traces I figured out the holder movieClip has no width and height. Is this normal? I thought the movieClip is supposed to automaticly have a width and height assigned to it according to its content?

I'm trying to somehow target a MC being loaded into an empty container MC. I've tried everything I could think of.
Basically, I'm making a movie editor. Right now clips are added to the stage on initial load, then when they are clicked on they are added to the "reel" and they can be previewed in the order that they are added. Now, I'm trying to get it so that when they are on the "reel" they can be click and dragged and rearranged.
Here's how the clips are added to the stage in a function called loadClips():
ActionScript Code:
addChild(clip1);
clip1.name = "1";
Here's how they are being added to the "reel" in addClips():
ActionScript Code:
if (currentTarget.name == "1")
{
clipCopy = new Clip1();
[Code]....
Now, I just want the clips that are on the reel to be click and drag-able (along the X axis but I'll worry about that later). I realize now they're all being added as clipCopy. That's going to be an issue huh? Is there a way that I can target the container and make that mobile?

Rather than typing out each child to add to a container mc, I wish to use a for loop to do so. However, in AS2, when adding an instance of an object, I could specify a unique name based on the current number of the loop. In AS3, I dont know how to even give the same object a unique name if multiple versions a re being pulled from the library to the Stage!
See this step of basic code:: and perhaps someone may have an obvious point to make about the differences of standard procedures, moving from AS2 to AS3::�
Code:
var container:MovieClip = new MovieClip();
var wing:MovieClip = new MovieClip();
addChild(container);

Is there a simple way to completely empty a display object container regardless of what it contains, including if it's already empty? In other words, without determining its children and using removeChild on each?

I have a main SWF with an empty MC holder and all of the main navigation button on actions. When the buttons are clicked it then loads an external SWF into the empty MC. I am having trouble telling the button to load the movie once and then stop loading if someone clicks on the link again. I want to prevent someone from double clicking to cause the animation to blink. *rapidly click on "home" to see what I mean.
[URL]
All of my button actions look like:
home_btn.onRelease = function(){
loadMovie("images/6661_home.swf", _root.dropzone);
}
I have read numerous threads but for some reason can't find a fix for this.

I am creating a container. When I press a button outside the container it adds a movieclip. The movieclip is the width of the container but only a fraction of the height.
I need to know how to get it so every time I press the button it adds the movieclip after the last one, almost like appending a list. Does anyone know how I would do this?Do I use an array or does flash have some sort of table feature?

I have a multiple choice quiz designed for a client. I have an array that works thruout the questions, that if the user answers incorrectly, it stores the question number in the array. When the user reaches the end of the quiz, I dont want this array to always display at the end, since the user could have all the asnwers correct (which means the array should be empty). I am trying to make an if else statement that will display a different message if the array is empty.[code]...

Is there a simple way to check if an associative array has anything in it whatsoever? Not looking for a specific key/value, but rather if there's *anything* in it, similar to checking if a normal array is empty by checking it's 'length'.

I have 3 input texts on the stage.
money_input
percent_input
years_input
what I want after pressing the button (calculate_btn)is to get thees values entered from these input texts into 3 vaiables.
var $money
var $percent
var $years
and check if the inputs are numbers only not string not empty. I tried to convert the inputs to numbers to insure that they are numbers without making a function to check the inputs but always I get NaN when I entr value like 444bb;
ActionScript Code:
error_txt.text = "Enter some values to calculate your loan";
//--------Make the button listener----------//[code].........

I want to check if an input text field is empty. I only managed to do it this way;
mytext = textfield.text;
if(mytext != "") .....
The problem with this approach is that I also want to exclude variables with whitespaces.
I tried; if(!isEmpty(mytext) )..... but that didnt work.

I need a fairly foolproof way to check from a child swf whether it is loaded into a container swf through a loader object or if it is just loaded through html. I would like to do this without requiring a flashvar or any kind of function call from the parent swf that may be there. Any quick and simple solutions? I looked for something with loaderinfo but came up empty.

How can I check how many movieClips exist in a container and how much space are they taken?
In other words, how can I make this calculation if I have a rectangular movieClip (containerMc) that is 5x1px and five square movieClips (sq1Mc,sq2Mc, sq3Mc, sq4Mc and sq5Mc) that are 1x1px and which can dynamically be placed inside containerMc and I want to know how many and which of these five movieClips already exist in containerMc so I can determine where the next square movieClip needs to be placed?
Can someone be so kind and show me how to do this or direct me where I can find the answer?

I have a problem with buttons and transitions and it is similar to a problem I had a couple of days ago that I posted and that was sorted out. I have two buttons onstage (they're inside a movie clip) inside the movie, on the button one I have the following
[Code]....
I have similar code on button two and this does indeed make the buttons move into place as required. My problem is this, I need to load in external swf files into an empty movie clip on the main stage called container. These External SWF files have transitions and this is where my problem is. If I place a normal button on the stage it works but not if the button is inside a movie clip and has actions applied as above. The code next is what I have believe should also be placed on the button to make swf transition one load in.

I am creating a site where there is a portfolio section with icons for each piece of artwork.Regardless of which icon 1-10 is clicked, for the first time ONLY, I want to load a swf which "draws in" a portfolio "background", and another swf on a higher level which corresponds to the icon clicked (lets say a sample artwork).
However, if the user has previously clicked another portfolio icon and is currently viewing one of the portfolio pages, there is no need to load the "background" swf again (it would be tedious watching the drawing in animation over again).
I've designated a target container movieclip for each.The icons swf file with the buttons is another swf on the timeline.Is there some code which can check to see if the background swf is already loaded into its container? And in which swf would I attach the code?
