[Flashcoders] Searching all ActionScript in an FLA
I have FLA files from a client with numerous MovieClips and buttons containing ActionScript all over the place. I am not used to this, I only started using Flash with AS3 and have always used a Document Class and placed my ActionScript in external .as files. I am trying to search through the ActionScript to find some text. Is their any way (tool etc.) to search through all ActionScript in a FLA? Why doesn't Adobe put in such a search function, it sounds so basic to me. Or am I not understanding something about Flash usage? Thanks. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] MouseEvents on overlapping siblings in AS3
Here's a very good article about how mouse events propagate. http://www.adobe.com/devnet/actionscript/articles/event_handling_as3.html You should be able to have more than one MC capture a single event, although I haven't tried it.

Re: [Flashcoders] pythagoras question
I think this is what you need. --- angle = Math.atan2( endY - startY, endX - startX ); trainX = vectorLength * Math.cos( angle ); trainY = vectorLength * Math.sin( angle ); --- Notes: 1. I'm using atan2(), not atan(). 2. The function atan2() takes (endY - startY) as its first parameter, and (endX - startX) as its second. It's easy to make the mistake of assigning them the other way round. Hope this helps.

Re: [Flashcoders] Function = String
I'm pretty sure there is no reflection-type functionality in AS3 to return a method name. Maybe you can define a bunch of string constants (perhaps even as static members in a class you create for this purpose, to hold them in one place) and use them as parms to addCallback(). Then you would still have to make sure there are no typos in the function names you use to initialize them, but the compiler will inform you whenever you are spelling them incorrectly when sending them as parameters to addCallback(). (I hope I am understanding your question).

It's not a huge problem but (as with everything in the ExternalInterface) it seems like the implementation wasn't thought out, and doesn't jive with the rest of the language.

Re: [Flashcoders] pythagoras question
Let's call the position of the mouse click on the stage (clickedX, clickedY) The starting coordinates are (startX, startY) The ending coordinates are (endX , endY) The general equation of your line, for any variables X and Y, is: Y == (X - startX) * (endY - startY) / (endX - startX) So when the user clicks on the stage, the values of clickedX and clickedY would need to satisfy the following equation: clickedY == (clickedX - startX) * (endY - startY) / (endX - startX) If this is true for clickedX and clickedY then that means the click fell on the line. Of course you would probably have to provide a bit of an error margin because you can't accurately evaluate the equality (==) of real numbers.

[Flashcoders] Fading previously-drawn lines
Hello, I am a Flash newbie, but an experienced programmer (C/C++). My requirement is to have an arrowhead traveling along a specific path on the stage, leaving a trail behind. As the arrowhead moves along, the trail left behind needs to progressively fade. The oldest part starts fading first, so it is always the most faded. By the time the arrowhead reaches its destination the oldest part of the trail, furthest from the arrowhead, should be quite transparent, maybe an alpha value of 10% or so, and the newest part of the trail, adjacent to the arrowhead, should be a solid 100%. The motion of the arrowhead was made by an animator. I need to work with that. I am currently doing this as follows: 1. I start out by initializing a Shape, with a thick solid (red) line style. 2. I set the drawing pen position at the initial position of the arrowhead using moveTo() 3. One each ENTER_FRAME event, I use lineTo() to draw a line to the current position of the arrowhead. And so on. So what I would like to do is in each frame, after several frames have elapsed, is to start fading the oldest line segment, then a couple of frames later start fading the second-oldest, while continuing to further fade the oldest, etc. Is it possible to access the older lines? I know how to fade the entire Shape (trapezoid?) but not specific segments. I tried the method of creating a new Shape every frame, just a line segment, that I accumulate in an array. That way I can fade them all separately according to how old they are. However the problem I had with this was that the lines end up overlapping at a point, because I was doing the following. Frame n: create new segment moveTo( 100, 100 ) // the previous position of the arrowhead lineTo( 104, 104 ) // the current position of the arrowhead Frame n + 1: create new segment moveTo( 104, 104 ) // the previous position of the arrowhead lineTo( 100, 108 ) // the current position of the arrowhead So both of the lines share a point at (104, 104). As I fade out the lines by decreasing their alpha values, it seems at this shared spot the alpha values have an additive effect, and the spot is more opaque. So the end result is that while the path is incrementally faded as I want it to be, it is punctuated with these thick spots. I don't want those, I just want a smooth continuous incremental fading. Is there a way to access the pixels of that spot, where the two lines intersect, and fade them to some transparency level? The lines are a few pixels thick (maybe 2 or 3 or more, depending on what the client likes) so that interecting point is not just a single pixel. I also tried staggering the starting point of each new segment, based on the direction of the line, so that it doesn't overlap with the previous line. But this was really ugly and jagged looking. There may be an intelligent algorithm or heuristic for this but I don't have the time or budget to make a big deal of this. Here is a link to help clarify things. It doesn't satisfy the requirement, since there is no incremental fading, it is all equally faded except for the line attached to the arrowhead. It also doesn't exactly employ the methods I describe above, it is just one of my many trials incorporating a few technquies. I am just linking it to help this discussion. If, on the other hand, it is confusing please ignore it. http://arka.sunnyday.jp/script/escort/hokkaido_01.html Thanks, Arka Roy ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Nested SWFs
I don't think this is possible, unless you actually load that asset library
from within the page1.swf's document class.
Here is how I instantiate assets from an asset library.
--
private function loadAssets():void
{
var req:URLRequest = new URLRequest( myPath/myFile );
var ctx:LoaderContext = new LoaderContext( false,
ApplicationDomain.currentDomain );
var ldr:Loader = new Loader();
ldr.contentLoaderInfo.addEventListener( Event.INIT, loadAssetsDone );
ldr.load( req, ctx );
}
private function loadAssetsDone( e:Event ):void
{
var assetClass:Class;
assetClass = getDefinitionByName( myAssetClass ) as Class;
// mAssetObj needs to be declared somewhere
mAssetObj = new assetClass();
}
--
I wonder if instead of the way I'm doing it, you were to hold onto assetClass
as a member variable of the index.swf document class, for example mAssetClass.
One thing to try would be to pass this as a parameter to your loaded
page1.swf's document class and then trying to do a new assetClass(); on it. I
have no idea if this will work, maybe you can report back.
Sorry for only being able to offer a shot in the dark. I've had a tremendous
amount of grief myself with loading swfs within swfs, and also with asset
libraries. Flash behaves in all manner of unpredictable and unintuitive ways.
One basic problem is that I don't deeply understand the concept of a
LoaderContext or the ApplicationDomain, and have not had the time to look into
it.

Subject: [Flashcoders] Nested SWFs
Hello all,
I'm new to AS3 and using multiple SWFs in an application. I'm used
to AS2 and 1 or 2 SWFs at max.
I'm using the GAIA framework (not sure if you're all familiar) which
seems to rock so far!, but I'm confused on a couple issues:
I have a few SWFs that load into one another (i.e., main/index/nav/
page1).
I would like to load a remote asset library into the index.swf (since
this page never unloads) and access the contents of the library from
page1.swf (and page2, page3, etc.).
I can get everything to load fine and all my movieclip classes are
accessible from the SWF that I load the remote library into.
I just can't figure out how to target them to create new instances
through the page1.swf?
Does that even make sense???
Any help would be greatly appreciated.
Thanks in advance,
_mike g.

[Flashcoders] Getting dimensions of visible area
Hi, My first post. I'm a newbie at Flash but was a game programmer (C/C++) for a long time. I'm finding Flash to be highly quirky and very interesting. I have a question about images imported from Illustrator CS3 with masks. These images have artifacts outside of their visible area. For example, it can have a picture of a dog's face, but one of the long ears is off to the side, outside the visible region of the piece. We cannot crop the piece for our own reasons, but the mask makes it such that the ear sticking out is invisible in Flash, when we turn it into a movie clip. Also, the Info panel in the Flash IDE correctly shows the width and height of the visible area ONLY. However, in ActionScript when I try to get the width and height using the DisplayObject width and height properties it returns the dimensions of the entire image including the hidden portions. You can see them here: Visible area only http://arkaroy.e3b.org/scraps/piece.jpg Entire image with visible area masked in red http://arkaroy.e3b.org/scraps/mask.jpg I want to be able to get the width and height of the visible area in ActionScript. Is this possible? The fact that the Player knows there is a mask and correctly hides the outer parts indicates that it should have that information somewhere. By the way, all mention of dimensions I've made here pertains to bounding boxes.
