Re: [Flashcoders] Letting go of AS2 for AS3
Hi
I didn't try yet to code in AS3 with Flash9. I choose to develop with Flex2.
I don't know now all about AS3 but:
With Flex, I build a kind of main class, like all other classes, but without
constructor. My app in MXML (only 4 lines of code) just define what is the
main class and whitch method of this class it does to call first. After
that, all is in AS3. My classes and also my main class are coded in *.as
files.
I've seen in Flash9 that with FilePublish settingsFlashActionsScript
version: ActionScript3.0Settings, you can define a single document class.
It seem's to be the main class whitch start playing the swf.
I tryed quickly to build an app with it, but it didn't start... sorry to
can't help you more...
I hope I bring a few light in your mind...

Subject: [Flashcoders] Letting go of AS2 for AS3
Okay im in the middle of reading AS3 Cookbook, and Essential AS3. And i'm
having some trouble grasping the concept of the main class file {as in the
root package for the program you are constructing}, both books talk about
this. But are they talking about constructing applications using MTASC/mxmlc
compilers or is there a way using the Flash 9 IDE to create a main class
file that the IDE needs to look for. I know u can write code on the
timeline, of course, but just wondering if there some other way which they
are elluding to, and me being slow am just not gettin'...
Thanks!

[Flashcoders] Mouse and ActionScript3
Hi list... Sorry for this so simple question... but I didn't find an easy way to replace onReleaseOutside event in ActionScript3. The MOUSE_UP event doesn't fire if the mouse is outside the displayObject... So I test the MOUSE_UP event of the root display object, and transfer the value to my object... but it's not a nice solution...

Re: [Flashcoders] efficient line segment intersection algorithm?
Hi I test myself with only lines in the two movieClips, hitTest works fine without fills... David Buff - Original Message - From: Millie Niss [EMAIL PROTECTED] To: Flashcoders mailing list flashcoders@chattyfig.figleaf.com Sent: Thursday, November 09, 2006 4:01 AM Subject: [Flashcoders] efficient line segment intersection algorithm? As part of an app I'm writing, I need users to be able to manipulate a drawing of a graph: Specifically, I have a bunch of circles (nodes) connected to each other by line segments (edges). Users can drag the nodes around within a fixed area (this part works), but I need to stop them from making the edges intersect each other (except where they meet at the nodes). I tried to do this using MovieClip.hitTest (each edge is its own MovieClip, and I know the coordinates of all the nodes) but it didn't work. I am sure there is a bug in my code, which I need to find. Even if I fix it, however, the stupid algorithm that goes through every node and checks if it hits any edge in the obvious (2 nested for loops) way is horribly inefficient -- I probably need to do the math myself rather than relying on hitTest. The number of nodes is user-configurable so even if I get the stupid algorithm to work on my baby test case, I am worried that it won't scale. It occurred to me that possibly hitTest doesn't work to check whether a point intersects with a clip that has strokes but no fills (ie my edges)... Does hitTest use the pixels of strokes or does it only use the insides of fills as the area it checks the test point against?

Re: [Flashcoders] Q:Playing with BitmapData
Hi
I didn't find a better solution than two x and y loops... (other loop
solutions I tested are not faster)
Just note than copyChannel is a method 3x slower than copyPixels
If you need to loop on your BitmapData, may be doing a setPixel inside the
loop to build your channel Bitmap is more faster than doing your loop and
then 3 copyChannel...
The better method I found (the fastest) to get or set r,v,b components when
you extract a color with getPixel is:
to get color:
arvb =
{alpha:color24,red:(color16)%256,green:(color8)%256,blue:color%256};
to set color:
color = (alpha8)+red)8)+green)8)+blue;
good luck

Subject: [Flashcoders] Q:Playing with BitmapData
Hi
There are two things I am trying to do with bitmap data.
The first is to analyze every pixel in an image using getpixel and then
store this info as xml data for later manipulation.
Can anyone offer suggestions to speed up this process?
The second techinique is to simulate splitting up an image into its
corresponding red, green and blue channels, showing how a 'true color'
image is achieved when these three channels perfectly overlap one another.
Do I simply need to use the Copychannel method of the BitmapData object
for this?
Thanks in advance!

Subject: Re: [Flashcoders] find same label
Hi
I'll do something like this.
First create a empty array. Then loop into your ComboBox like I show you
before. Each step of the loop, test if the value is allready in the array.
There is no method of array class to do that, but you can cast the array
as string and use the method indexOf of the string class, something like
this:
if (myArray.toString().indexOf(myValue)==-1) { ...
-1 means that the value is not in the string, then it's the first
occurence of this value. So push the value into the array for futur test
and push also this value into your second ComboBox.
If the value appears again, indexOf will return a positiv or 0 number,
then it's not pushed into your second ComboBox.

Re: [Flashcoders] Bitmap filters
To invert your image, just create a MovieClip in your library, then put your
picture inside, and link this MovieClip with the id: picture_id.
the code is:
import flash.filters.ColorMatrixFilter;
var matrix:Array = new Array();
matrix = matrix.concat([-1, 0, 0, 0, 256]); // red
matrix = matrix.concat([0, -1, 0, 0, 256]); // green
matrix = matrix.concat([0, 0, -1, 0, 256]); // blue
matrix = matrix.concat([0, 0, 0, 1, 0]); // alpha
var filter:ColorMatrixFilter = new ColorMatrixFilter(matrix);
_root.attachMovie(picture_id,pictureMc,1,{x:10,y:10});
pictureMc.filters = new Array(filter);
To understand:
I you take the exemple of a 100% red picture, you've red=256, green=0,
blue=0. The invert of the red is cyan: red=0, green=256, blue=256
Then reed the oline help of colorMatrixFilter, you can see that:
redResult = a[0] * srcR + a[1] * srcG + a[2] * srcB + a[3] * srcA + a[4]
so the first line of your matrix is -1,0,0,0,256 so redResult = -1*srcR + 0
+ 0 + 0 + 256 -- srcR = 256 and -256 + 256 = 0 the result is 0
so the second line of your matrix is 0,-1,0,0,256 so redResult = 0 + -1*srcG
+ 0 + 0 + 256 -- srcG = 0 and 0 + 256 = 0 the result is 256
same for blue.
Your global result is red=0,green=256,blue=256 it's a invert image.

Re: [Flashcoders] attachbitmap and copy pixels.
Just explain a little more...
subPicture.copyPixels(picture,new
Rectangle(xPos,yPos,subPicture.width-borderSize*2,subPicture.height-borderSize*2),new
Point(borderSize,borderSize));
It's mean:
-subPicture is the BitmapData where you want to copy the pixels
-copyPixels is a method of BitmapData object
-picture is the BitmapData witch is the source of pixels
-new Rectangle is a flash.geom.Rectangle object, witch define the top left
point of the part of the source picture (inside the BitmapData here called
picture) you want to copy, and the width and the height of this rectangle
-new Point is a flash.geom.Point object witch define the top left point
inside the destination BitmapData where you want to copy your pixels
(usually (0,0) but you can choose something else)

FlashCoders,
Selection.getFocus() gives back a String. Is there a way to get the

Re: [Flashcoders] doLater not working
I think... You have to be attentive about the fact that flash execute the code from the upper layer to the lower layer. So if your _root.panelBG.sp.doLater(_root, displayCorrectFrame); is written on a layer witch is upper layer of the one where is created your scrollPlane, this last one doesn't exist when the function is called... Try to write tour _root.panelBG.sp.doLater(_root, displayCorrectFrame); on the frame 2, if it works, it's because you don't do the things in wright order...

Re: [Flashcoders] Weird image download problems in IE
One way could be to draw a part of your image into a small BitmapData then
do a getPixel, if the value is not 0, your image is loaded. I've a problem
with IE and the flash loader too. But it's with request on cfm pages. After
200 requests, the connection come back with success, but the values are
undefined... I work on this since a week without finding a good solution...
This problem appear only with IE7. It seem's that there is actually a
problem with IE and Flash. Have you also this problem only with IE7 or with
all IE releases ??

there is a bug in the loader component, which might be whats bothering you

Subject: [Flashcoders] Weird image download problems in IE
We're running into a really strange problem with image downloads in
Flash when running in IE and was wondering if anyone else has seen
something like this or has any ideas on what I could do to fix it.
We need to have the Flash movie be able to download arbitrary images
from the web and display them. I also need to be able to tell whether
the download worked or not, so I can display an error if it failed or
manipulate the image if it loaded.
The problem we're running into is that in IE the loader class will
tell us the image failed to load even though it worked fine. Here's
some test code we used to test:
---
import mx.controls.Alert
this.createClassObject(mx.controls.Loader, my_ldr, 10);
var poLoaderListener = new Object();
poLoaderListener.oScope = this;
poLoaderListener.complete = function(oEvent)
{mx.controls.Alert.show(oEvent.total); };
poLoaderListener.progress = function() {};
my_ldr.addEventListener('complete', poLoaderListener);
my_ldr.addEventListener('progress', poLoaderListener);
my_ldr.load(IMAGE_URL);
---
When running this in Firefox it works fine, and the alert box gives us
the right value. However, in IE when trying this the alert box pops
up with a -1, telling us the download failed. However, the image still
shows up.
The only thing I've been able to figure out is that the speed of the
download has something to do with it. In the actual product we're
downloading the images through a server that acts as a sort of proxy
which caches the images. The first time we hit it the proxy has to
download the source image before returning it to the client. This is
when we see the problem. Later attempts seem to work fine as the
download happens faster (the server cached the image so it doesn't have
to
redownload it).
To simplify the test I took the proxy out of the loop and threw a
bandwidth limiter on the server that had the image I was testing.
When throttling it back to act like a 56k modem I could reproduce the
error in IE. It still worked fine (just really slow) in Firefox.
Has anyone seen this before? It's causing serious problems, as we
need to be able to tell if the image downloaded successfully or not.
Any ideas of ways to get around this or fix it? Note that we have to
support Flash 7+.
Thanks!

[Flashcoders] Problem with response of cfm pages especially with IE 7.0
Hi FlashCoders !
Sorry again for my bad english...
We've a big and curious problem with cfm pages, since one week, without finding
a real solution.
It seem's there is a problem beetween flash player and navigator especialy IE
7.0
We build online games, and this games make request to the server using cfm
pages (ColdFusion 5.0 and Flash 8 pro).
For exemple, the Flash ask to the map description off a game, like:
http://www.domaine.com/game/general.cfm?action=ask_map
and the cfm page return:
id_map=152map_description=5,6,9,1,2,3,8,4,5,6,1,5,3 etc...
With IE 7, after 200 or 220 requests to the cfm page, the connection return
with success but the params are undefined. We need to clear the cache of IE
to be abble again to get params from the cfm page, and this only for 200
requests again.
We've verifyed with the plugin HttpWatch that the connection was success, and
that the params was correctly returned by the cfm page. So the navigator get
the params, but did'nt pass theym to the flash player.
We've try to add a timer (date+time, it's a unique number, better than a random
number) to the URL like:
http://www.domaine.com/game/general.cfm?timer=121546546685211action=ask_map
... doesn't change anything
We've try to add the timer befor the ? of the URL with a \ (not /) we
send something like:
http://www.domaine.com/game/general.cfm\timer=121546546685211?action=ask_map
(The navigator automaticaly correct \ in /, I don't know if this is important
to explain)
With this solution, we did'nt have any problem with IE 7, but it start to be
worst with FireFox especially release 1.5.0.7
I test today with a cookie on one game, around 1500 gamers (about 100 requests
by gamer), there was 4% of theym who has a connection witch comes back with no
success and 1.3% witch comes back with success but where the params are
undefined. When connection work wrong, the game test automaticaly again the
connection a second time. Only 0.4% of the gamers ware not abble to get a good
connection again. But it seem's hudred by day...
Does anybody have a similar problem? any solution?
The flash code is something like this:
var varLoader:LoadVars = new LoadVars();
function askMap() {
varLoader.onLoad = _root.askMap_callBack;
varLoader.sendAndLoad(http://www.domaine.com/game/general.cfm?action=ask_map,varLoader,GET;);
}
function askMap_callBack(success) {
if (success != true){
trace(no success);
// do something in the game
}else{
trace(success);
for (var i_o in varLoader) {
trace(param:+i_o+ -- +varLoader[i_o]);
}
// do something in the game
}
}
it returns (trace):
success
param:id_map -- 152
param:map_description -- 5,6,9,1,2,3,8,4,5,6,1,5,3 etc...

Re: [Flashcoders] CacheAsBitmap advice
With BitmapData, you can build a BitmapData of your picture, for exemple 1000x600 witch will stay in memory, and will not be displayed. After that, you create another BitmapData witch is only 500x300 for exemple, the size you need for display. Then you draw the first BitmapData in the second with the draw() method, according to a geom.matrix witch describe the translation you need for scroll, and also the zoom. Doing this, your scroll and zoom will be faster. Remember that the cacheAsBitmap property is true by default. May be there isn't difference in you're test because you didn't try to define cacheAsBitmap as false (and only compare default and true, witch is the same thing). I went to your site. It seem's that when we zoom in a picture, this picture is first reduced like 20% and when you zoom, you increase to 100% with a mask. Am'I wrong? In this case, and also for the scroll, you will not realy increase the speed with cacheAsBitmap. But I think you can do much better using BitmapData, scroll(), draw() and flash.geom.matrix in the draw() method. always sorry for my english David Buff - Original Message - From: Jason Ross [EMAIL PROTECTED] To: Flashcoders mailing list flashcoders@chattyfig.figleaf.com Sent: Wednesday, October 11, 2006 1:36 PM Subject: RE: [Flashcoders] CacheAsBitmap advice Hi - thank you to both Ian and Ramon.

Re: [Flashcoders] Playing video backwards kills my CPU
sorry for my bad english... There is two kinds of movie codec for the compression, first using spacial compression only (like mjpeg...), and second using spatial compression in association with key frame (like mpeg, sorenson...). The key frame describe the entire picture only once each 15 frames or 8 frames for exemple. The other frames describe only what has changed in the picture, with a threshold. It describe for exemple only the arm of a people who's moving, but not the background witch do not move. So when you want to read a movie forward, the codec read the key frame witch is the reference to fill the holes not described in the other frames. Each 15 frames, a new key frame describe the entire picture (so also the background) and define a new reference for the next frames. The problem is that when you want to play backward, like frame-1, the CPU need to go 15 frames before to find the previous key frame, load the entire description of the picture, and build frame by frame, fill the different holes of each frames, to be able to display the frame you want. If you are lucky, your index (frame-1) is the index of a key frame. Then the CPU work quickly. But if you are not lucky, your index is (key frame - 14), then the CPU need to rebuild 14 frames to be able to display the one you want. There is no solution to your problem, because Flash don't offer the possibility to use a only spatial codec compression. And this kind of compression take a lot of Mo because all frames are described. I thaught to an alternative but never tried it, you can try to draw each frame of your movie in so many BitmapData you need. It will take a lot of memory space, and a preload time, but after that, you index the BitmapData you need, and it will work faster. I don't know if it is possible to draw a .mov frame in a BitmapData. If it's possible, tell us.

The key frame describe the entire picture only once each 15 frames or 8 frames for exemple. The other frames describe only what has changed in the picture, with a threshold. It describe for exemple only the arm of a people who's moving, but not the background witch do not move. So when you want to read a movie forward, the codec read the key frame witch is the reference to fill the holes not described in the other frames. Each 15 frames, a new key frame describe the entire picture (so also the background) and define a new reference for the next frames. The problem is that when you want to play backward, like frame-1, the CPU need to go 15 frames before to find the previous key frame, load the entire description of the picture, and build frame by frame, fill the different holes of each frames, to be able to display the frame you want. If you are lucky, your index (frame-1) is the index of a key frame. Then the CPU work quickly. But if you are not lucky, your index is (key frame - 14), then the CPU need to rebuild 14 frames to be able to display the one you want. There is no solution to your problem, because Flash don't offer the possibility to use a only spatial codec compression. And this kind of compression take a lot of Mo because all frames are described. I thaught to an alternative but never tried it, you can try to draw each frame of your movie in so many BitmapData you need. It will take a lot of memory space, and a preload time, but after that, you index the BitmapData you need, and it will work faster. I don't know if it is possible to draw a .mov frame in a BitmapData. If it's possible, tell us.

Re: Re: [Flashcoders] Playing video backwards kills my CPU
Yes, i'm not sure to understand this post, but the way is to build 2 movies, one running in the original direction, and another running back. So when you want to read forward, you index the frame of the first movie, when you want to read backward, you swap your movie, and index the frame of the second movie (witch is running back).

This solution is feasible if your .mov displays a 3D model and you want to reverse an animation maybe... You need to look at your brief, asses why you are trying to rewind the video, and then look for the best technology to do this. Telling flash to go through your compressed movie backwards frame by frame is lunacy (as you are finding out the hard way). Sort it out, or your clients expectations (or even your own!).

It's probably neither one of those alternatives - it's more like a fact of life. The way temporal compression works for video is by having one keyframe (the entire image) followed by several frames (chunks of image that only specify changes to the image data). When doing forward this is fine, but when seeking to a different frame, the render has to actually go to an specific keyframe, then render forward to the specified frame. Because of this, going backwards really *is* much more difficult to any player or codec (unless you have one keyframe every frame, which defeats the purpose of temporal compression). If you're having that problem, try lowering the steps between keyframes on your video (say, one keyframe every 15 frames instead of one every 30 frames). It should make things better, but at a cost - your video file will be bigger.
