I want to check in my function if a passed argument of type object is empty or not. Sometimes it is empty but still not null thus I can not rely on null condition. Is there some property like 'length'/'size' for flex objects which I can use here.

With brush_mc you can brush over a mask, wich turns the pixels to transparent in brush strokes.So visually it erases the mask and the masked movieclip appears. I want to trace, if the mask is completely turned transparent. Is it possible to check if the mask is turned completely transparant without bitmapdata?
// this creates a mask that hides the movieclip on top
var mask_mc:MovieClip = new MovieClip();
addChild(mask_mc)

I´m loading some MP3 from an external URL. I need to wait to completely load the mp3 and then start to play it. Do you know how can I check when mp3 loads completely? This is my code:
var s:Sound = new Sound(new URLRequest("url.com/file.mp3"));
var channel:SoundChannel = new SoundChannel();
channel = s.play();
Is there a static property in Action similar to that in the String object in .net to check if a string is empty, that is String.Empty.
View 2 RepliesI 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]...

How to check if a string is empty?

View 1 Replieschecking 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 installed said program but whenever I add users, it says they were added successfully and exist in CMD.However when I check the users.dat file it is empty. When I try Live Encoder it says the user does not exist.

View 12 RepliesI 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]
View 14 RepliesI 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 want to know how to access a variable that was declared in a completely different frame. How do i make it global or whatever in as3?
View 9 RepliesAll of the bullets are of the "Bullet" class and are stored in an array called "bullets" in the main class. When bullets exit the screen, removeBullet(bulletID) in the main class is called.
private function removeBullet(id:int)
{
removeChild(bullets[id]);
bullets.splice(id);
}
In my Bullet class I have an enterFrame listener that traces "stillHere". So as soon as a bullet is added to the main stage using addChild, "stillHere" starts popping up in my output panel.
My problem is that even after I call the removeBullet, "stillHere" keeps popping up in the output panel, which tells me that the object which I tried to delete is still sticking around somewhere in the memory.
I'm having some trouble with fully deleting object references. My object (a displayObject) has an ENTER_FRAME eventListener with weakReference set to true. It simply traces "hello" every frame. Then in my document class I try to delete it as follows:
Code:
delete(removeChild(obj));
. Despite this, the eventListener keeps on printing "hello". And I don't believe I have any other references to the object lying around. But in case that is true, is it possible to print the number of references of the Object?
To remove a dynamic displayObject completely you need removeChild or removeChildAt(index) remove all the refrences to the displayObject nulling the displayObject
But this is my case
PHP Code:
//here recto is a MovieClip on stage//i creat a dynamic display Object named newMcvar newMc:MovieClip =new MovieClip();newMc.graphics.beginFill(0x000000,1);newMc.graphics.drawRect(0,0,10,10);newMc.graphics.endFill();recto.addChildAt(newMc,1);//i refrence the newMc using
[Code].....
I believe that it is refrencing newMc but I am not sure why nulling refrenceMc has effect on newMc

i have a swf file of width 1000 and height 700. i want to show the swf file in full screen of the browser it self (not like videos plying full screen). i tried like the following
1) get user screen width and height using java script using the functions available (screen.availHeight and screen.availWidth) the screen size is available by using the functions but not applying to the flash object
2) tried giving 100% for both height and width in object code that also not working
In document class action script file I add a movie clip to stage using
Code:
public var square:Square
square = new Square
addChild(square)
So it adds square to stage.Then after sometime I want it to be removed. I call a function "removeSquare" also located in document class. It executes the following code. And it removes the square from stage visualy.
Code:
trace("proff that it's executed")
removeChild(square)
square = null
Then of course I want to add a square to stage again, using code I written at top of the post. And remove it again, and so on..But game is lagging more and more and more. So I guess that the square is not properly removed. If you need more details about my code feel free to say, I just written that since I really doesn't know what else should be important.
I'm creating a small drag & drop activity, and I want to be able to check and see if the dragged movie clip is completely within the bounds of another movie clip (or at least in the bounds of a certain x/y zone on the main stage. I can't use dropTest because it returns true if any tiny bit of the movie clip overlaps with the dropTest movie clip.
I also thought of something that just checks the x/y coordinates of the dragged movie clip, but I'd need this to reflect a range of values rather than one coordinate. For instance, I'd want to return true if the movie clip's x is between 50-60 AND the y is between 50-60. I'm attaching a small graphic to illustrate in case my explanation isn't clear enough [URL]

View 11 RepliesI'm having difficulty accessing a variable value within nested MCs.
On Scene 1 in the addFullPanel function, the variable panelNames exists.
However, I'd like to use this variable value within the MC FullProjectPanel in the switch function in order to load a corresponding xml file.
As it stands the variable is empty within the FullProjectPanel function.
