In ActionScript 1 and 2, if you compare undefined, null or NaN with an arbitrary number using >= or <= operator, the result is always true. Test code:
var x, n, range = 1000;
for (var i = 0; i < 3; ++i) {
switch (i) {
case 0:
x = undefined;
[Code] .....
Furthermore, isNaN(null) return true. These are contrary to JavaScript and may not conform with ECMA standard.
I'm trying to figure out how to tile a rectangle (the stage) with an arbitrary number of rectangles. Simple tiling where all the tiles are the same size and simply stacked in a grid.I'm doing this with a resizable layout and a number of tiles that is arbitrary and will change over time.
Given a more or less 4:3 or 16:9 monitor I would like a solution that tends toward minimizing the perimeter of the tile and being similar in aspect ratio to the screen. I realize that if I have a prime number of tiles that I won't be able to make a nice grid, but other than that it seems there should be some way to do this.Lets say I have 231 tiles I need to arrange. The factors are 1, 3, 7, 11, 21, 33, 77 and 231.If the screen is really, really wide 1 x 231. Wide but not not as crazy wide as before 3 x 77. And most likely 11 x 21 is what I would need.So is there an easy way to do this on the fly? Is there a pre-calculated way to make it easy?
I want to seed a number generator using a string input. What function would be best for simply turning the string into a number to do this?
View 2 RepliesI'm wondering if its possible to resize flash with javascript. I can't change any code in the flash object alone all I have is html, javascript and php to work with. Heres what I've found so far:
[Code]....
Content Embed is the embed tag and content object is the object tag in the flash. This works in chrome (and probably firefox) but not ie. In internet explorer I get the error: Unable to set value of the property 'height': object is null or undefined Here is the example page I have been using:[URL]
I've got a function wich can accept a varible number of parameter with a rest operator. I want create an object passing the argument collected with the rest operator directly to a constructor without create an object and call an initializing function and without passing the entire array but the parameters ah I do with apply() function.

Is there any way to execute arbitrary code in Flash, like javascript's eval()? I'd like to take some code as a string and execute it, if possible
View 2 RepliesI have an arbitrary number of files that I need to load in an AIR app.I want to iterate through an array of File object and create and launch Loaders for each one's File.url.When they are done (event COMPLETED or IOErrorEvent.IO_ERROR), I want to stuff their data somewhere. If they fail, I want to make an exception report. I cannot find any way to reference the File object from the event listener (certainly not the IO_ERROR)The best way would be to create individual event handlers for each Launcher that had the File information "hard-coded" into it. At the very least, I could use the function itself as an index to a Dictionary:
foo(fileToLoad : File) : void
{
var theCompletedHandler : Function =
{
[code]....
Can I use event.currentTaget and use the Loader instance as an index? Will that have any weird dependencies ?
Is it bad to compare a unit or int to a number? Should they always be kept apart?
PHP Code:
var i:int=10;var n:Number=20;if(n>i){}
I have a 2 different date formats. 1) dd/mm/yyyy 2) dd-mm-yyyy
I want to compare these 2 date formats in Javascript or Actionscript.
the script i wrote is working fine. but the script attached to the flash player which i have no control over is throwing a script error (im using IE8).how can i fix this? if i run it locally there is no error.
'null' is null or not an object
try { document.getElementById("").SetReturnValue(__flash__toXML(function() { return document.location.hostname; }()) ); } catch (e) { document.getElementById("").SetReturnValue("<undefined/>"); }
but this is from flash script and i dont have control over it. it just say JScript - script block.
I created the following AS for a particular frame
Code:
cnx.addEventListener(CNXConnection.DIGITAL, onDigital_10);
function onDigital_10(e:DigitalEvent)
{
[code]....
While debugging everything works properly if I'm testing that frame.But, pushing a button in another frame, I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference at "frame number:raw number"
I'm quite sure that the problem is that the variable e.Join changes its corresponding e.Value pushing a particular button in another frame (as must be). Any ideas how to link that information to the frame that create the error?
I need to know if Null is the same as Undefined and then, is it the same in AS2 as it is in AS3?According to the help files in CS3:
Null: A special value that can be assigned to variables or returned by a function if no data was provided
Undefined: A special value, usually used to indicate that a variable has not yet been assigned a value.
If I parse an XML element with a null or undefined result, is it possible to display a blank text field rather than "null" or "undefined" in the field? It seems really basic but I'm drawing a huge blank.XML

I use this pattern to test for undefined and null values in ActionScript/Flex :
if(obj) {
execute()
}
Unfortunately, a ReferenceError is always thrown when I use the pattern to test for child objects :
if(obj.child) {
execute()
}
ReferenceError: Error #1069: Property child not found on obj and there is no default value.Why does testing for child objects with if statements throw a ReferenceError?
there is a problem with IE browser it does not recognize object HTMLEmbedElement and not proceed for further execution . i have no choice because there is nothing to be updated in programming code
View 2 RepliesI'm attaching as many instances of a MC as my xml child nodes length.So basically never know how many of them would be on the stage.Each MC receive actions to perform, nothing fancy and it basically works.But what I want to do is to know when the user has clicked once on any mc so this latter gets 'not enabled' until another MC instance gets clicked. (so my previous MC instance gets enabled, it acts like radio buttons )The point is I know how to do it when the total of instances is defined.I also know the basics of a loop , but I cannot figure how to set up a "toggle" to gets this 'radio button group behaviour
View 2 RepliesI am trying to use javascript to run AS3 functions. When I attempt to compile I'm getting an "Access of undefined property" error message. I've read a few things online about this but I'm still not understanding it. I want to have the flash file always listening for javascript.

I have this code in my application...
Code:
var returned:Number = ExternalInterface.call("returnEntryCount");

Code:Type mismatch in assignment statement: found Object where Number is required.
Flex complains if I want to create an object from a library symbol with linkage: 1180: Call to a possibly undefined method [linkage name]. So to avoid this, I create a class for that symbol, in this case extending BitmapData using Flex's new ActionScript Class feature. Flex create that class for me and the constructor looks like this: public function CustomBitmapData(width:int, height:int, transparent:Boolean=true, fillColor:uint=null)

is possible to draw a border around an arbitrary Shape (or Sprite) dynamically with ActionScript? From the IDE is really easy, just select the line color and click the Shape with the paint tool (S).How can we the same with Actionscript?
View 0 RepliesI have colour values from a Flash application that are ARGB format(A being the alpha/transparency value). I have to convert that long decimal number to a RGB/Hexadecimal number in Javascript. Do you know how I can extract the individual R, G, B & A values from a long(8 digit) number? Here's my function which converts a number to hexadecimal BUT its not good enough because it needs to convert the values individually(R,G,B,A):

View 1 RepliesSay I've got a utility class in which I would like to access the stage (in order to get the frameRate).
I don't particularly want to force the user to pass in the stage to each method or set a static property on my class before using it.
Is there any way to get ahold of the stage without it being passed in? All I need is the frameRate!
Below is code that populates a menu. Everything seems to work great, with no errors thrown, except for one crucial part. My megaPages array has the values ["HOME","BABIES","BRIDALS","MISC","WEDDINGS","ABOUT"], but the actual text that displays on screen (which is produced by megaPages) is like this:
As you can see, some of the text is arbitrarily being truncated. I've traced the text strings as they get passed through the various functions at various stages of the menu-build, and they are always right, but somehow when each DisplayObject make it on screen, letters get ommitted (notice though that 'HOME' abd 'ABOUT' are fine). I don't even know where to start with this problem.

I have a floor plan of a building in PDF that I want to visualize as a map, using tools like MapBox, FusionMaps, or AmMap. I am willing to redraw the floor plan if needed. What format should the map data be in? What kind of tool can I use to create that data?
View 3 RepliesI have several custom functions that I import as .as files, but I frequently have to modify them to suit projects, which makes standardization and version tracking harder.Is there a way to pass arbitrary expressions to a function when it's called? For example, if I write the function,
Code:
function foo(){
for(i=1; i<=1; i++){
trace(i);
}
}
would there be some way to attach an additional expression after the trace function during the function call? As in,
Code:
foo(do_stuff_here);
where the function would act as if it had said,
Code:
function foo(){
for(i=1; i<=1; i++){
trace(i);
[code]....
but without modifying the original function?I realize I could add an expression to the original function within a conditional, and toggle it via an argument within the call, but since I don't know what I'll add next, or whether I'll need it next time, this would become impractical quickly.
