ActionScript 2.0 :: Breaking News: "undefined" Is Greater Than Zero?
Nov 19, 2004
Don't know why this matters all that much, but if ANYONE can shed ANY light on "why" for the following behavior, that'd be great!I ran across this when I tested my program and I expected errors because of a couple undefined's but they went right through my if!
So I decided to check it out. I started with a couple tests and got the expected answers:

I'm prepared to find out that I'm the only one who cares, but if anyone else is interested, please post your thoughts!

Making an XML news reader based off of senocular Squirrel XML news.
I'm using Fuse and wanted to target the dynamic text and or background portions of the headline section.
However, this movie clip is attached to the menu_mc so I'm stumped as to what I should exactly target for the fuse sequence (or any mx.transition/zigo engine based code-tweening process for that matter).
I've attached the files in a .zip for people to look at (and possibly conquer my problem!

I wanted to add a second news box under the first one and have it pull the first two news items in the xml file and have it displayed on the movie. Currently it is putting the first news item in both news boxes.ction script so that the second box is actually the second "<news> tag". From the tutorial I removed the <info> <author> and <comment> tags.

Why would
if(vol > 0){
trace("worked");
}
NOT work if the value is a decimal value between 0 and 1?The trace only works sometimes. I didn't note though at what value it worked..STUPID ME...forgot and plus, it was 2AM.I am reading in an array ..byteArray, and then passing readFloat to vol.

I have just found out that flash wont let me create a movie with width or height greater than 2880. The thing is I have an image of the stage which has a height of 3568px so some clipping has occured and I cannot see the rest of the image when I publish the movie. Is there a way to somehow adjust my movie to this height so that I can see the rest of the image? I have assigned a little AS2 to resize the stage:
Code:
Stage.height = 3568;
However this doesnt work!

I am trying to loop through a bitmap and determine if each pixel is lighter or darker than gray using getPixel(). Problem is, I am not sure how to tell whether the value returned by getPixel() is darker or lighter than gray.
Neutral gray is about 0x808080 or R:127, G:127, B:127. How would I need to modify the code below to accurately determine this?

I have a scrolling flash gallery. On mouse hover over a thumbnail, a popup with more description is shown. The problem is that my stage height is 200px but the popup requires additional about 200px to show properly. When I embed this in an HTML page with the object tag height set to 200px, i see the scroller completely but the popup get cut from the top. If i change the object height to 400px, it show me the popup fine, but this inserts extra blank space in the html page.

i am using is flash cs3. the as2 swf contains a tween code using mx transitions.when i remove this tween code and hard code it on the enterframe there seems to be no problem.afaik avm2 should fully supports the as2 and as1 code. so i am unable to understand why this disparity when coding a simple tween in as2 swf.i had made a post in the actionscript forums hoping to gain some light on the issue.URL...[code]

what its meant to do: A casestudy, has a section for each client, showing a selection of work for each one. It starts at a random client/section each time it is loaded, and there is also a menu that allows you to go to a specific client/section if you want.
So what i've done is made a randomly generated var at frame 1, and then told it to gotoAndPlay different sections of my timeline
Code:
var myVar = Math.floor(Math.random() * 6) + 1;
if (myVar == 1) {
gotoAndPlay(5);
[Code]....
This is working fine, as is the menu. However, as soon as I add a new layer with 2 or more images, in any of the sections it stops working.
Stranger still, it seems to be if i use more than one of the same image type it wont work ie, 1 jpg, 1 gif, 1 png it still works, but if i have 2 jpgs or 2 gifs it will break.
I also tried making a movie clip to hold my images, but the same thing happens

I am working on a project where I need to show a wooden board and have the user pick a place on the board and somewhat realistically (at least believable) simulate the board breaking and shattering at that point. The final product will need to run on a mobile platform so performance is an issue.I have already experimented a bit and have a movie clip board which is composed of predetermined pieces and I used a tween to move the pieces apart. The main problem is that the way the board breaks and where it breaks are predetermined

If I want to break out of a function rather than a loop, it's suggested that I use the return; statement. But that doesn't work in the following code, I just want the trace statement to run once...
Code:
stage.addEventListener(Event.ENTER_FRAME, EnterFrameHandler);
function EnterFrameHandler(event:Event):void {
trace("It worked, obviously.");
return;
}
So, this will trace the phrase over and over with no stopping point. Why doesn't return have an effect? Doesn't the first line only happen once... ?

I have a datagrid that displays the contents of the array gotoArray[i], my only problem is that whenever an item gets added to the array the labels all go onto the same row instead of into sperate ones.
So it looks like this all on one row: Frame1, Frame2.....
Code:
_global.gotoArray = new Array(_global.BM_array);
function dataGridFunction() {
myDataGrid.setSize(260,115);
[Code]....
ALSO on an array note: How can I remove a value from an array according to it's index number - do I use the slice tool?

[URL]Is it literally breaking the video into frames or is it instancing the video a certain number of times and offsetting the next/previous frame?if it's the latter ... what's the most efficient way to handle that number of duplicates? I figure doing it that way would be too processor intensive ...

I'm currently working on combining a bunch of movieclips with variating color schemes that I'd like to condense into a unified pallete. Breaking apart a movieclip reverts the graphics to the original colors but it would be super-helpful if flash repasted the current color settings onto the graphics once its broken apart. Maybe implementing a few of illustrators color palette tools would be great too. If this isn't the proper place, then I apologize but I wanted to pass the info along as an artist who is currently using flash as his primary art development tool right now.

I'm using a game physics library (Box2D) which only supports convex polygon shapes. However, I'd like the level builder to be able to just specify concave polygons without having to worry about that. So, how can I automatically break apart a concave polygon into convex ones (or even all triangles). Speed would be cool, but ease of implementation is more important. The breaking apart will only be done on game initialization.

I'm having a really weird problem with the MOUSE_OVER event. I'm building dynamic tabs representing mp3 songs containing textfields with info and a dynamic image for the cover art. I am trying to get a simple MOUSE_OVER working over the whole tab, such that you can select the next song to play.
I am using a Sprite with alpha 0 that overlays my whole tab (incl. the textFields) as a Listener for MOUSE_OVER and _OUT... I've checked by setting the alpha to something visible and it indeed covers my tab and follows it around as I move it (just making sure I'm not moving the tab without moving the hotspot). Also, I only create it once my cover art is loaded, ensuring that it will cover that too.
Now, when the tab is in the top position, everything is dandy. As soon as I move the tab to make space for the next tab, the textFields break my roll behaviour... just like that noob mistake of overlaying a sprite over the one that you're listening for MouseEvents on. But... the roll area is still on top of the field, I've set selectable and mouseEnabled to false on the textFields... nothing.
