Re: [Flashcoders] Who wants MIDI in the Flash Player?
being able to read the data is cool, but just to say it one more time, being able to create audio data would be great. I do have one idea which i'll attempt if it doesnt look like we will get sound buffer access when the next player is released. As i mentioned earlier there is a Loader.loadBytes function which im hoping allows you to create and load swf's entirely in the player. So with a bit of trickery it might be possible to synthesize audio into a buffer, write it into a swf and then use the Loader.loadBytes to play it, all done in the player. I think one of the biggest challenges for this idea would be encoding the sound into the created swf, im not really up for writing an mp3 encoder in actionscript. But if there is a more simple encoding scheme that can be used then it would be one route to synthesizing and processing audio entirely in the client. Of course, it may even be possible to do something like create the audio in the swf as a streaming sound and just keep pumping bytes into the loader, but im getting way ahead of myself with that :) martin.

Re: [Flashcoders] Who wants MIDI in the Flash Player?
On another note I also think, particularly with the speed of 8.5, that it would be great to give us direct access to the sound buffer. I am not sure how fast 8.5 math will be but if you can do a good FFT we could be making actual synthesizers and audio processors in flash. To me that would be cool. absolutely, the 8.5 player already has an FFT (aka sound spectrum) function built in, but i think its buggy (this is what i have read, ive not tried it yet) Now, if they would add an inverse FFT as well then it would be fantastic. It would definitely take a load off the actionscript processing required if they were implemented natively. but at the very least access to the sound buffer would open up a whole new world. :) martin ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Who wants MIDI in the Flash Player?
Interesting question, although ive made use of midi everyday for, well, too long now :), im really not sure if making it part of the player as a single functional unit would be the best move. Personally i would rather see a more open, low level approach to sound in the player upon which MIDI and other implementations could be developed. Now that the player (8.5 and onwards) will have much better binary data handling, theres nothing to stop me or you from creating a MIDI file parser. Thats one side of the equation, obviously the more intricate side is audio playback. I've been moaning about the audio capabilities of the flash player for longer than i can remember, and would dearly love for it to become much more capable. The options i can think of so far are (and they arent exclusive) 1. An api for accessing midi devices on the user system, much like accessing a webcam, where you can query for which devices are present, then get a handle to a device and start manipulating it, something like: var midiDevice:MidiDevice = Audio.getMidiDevice(1); var instrument:Instrument = midiDevice.createInstrument(); instrument.setChannel(1); instrument.setProgramNumber(34); instrument.setController(23,44); instrument.noteOn(velocity); etc... 2. ACCESS TO THE SOUND BUFFER. Please. :) This would open up a lot more possibilities for audio generation, manipulation etc.. The 8.5 player already has a Loader.loadBytes feature where you can send binary data locally, i.e. you can create a jpg in the player and then load it into a movieclip without sending it to a server. This is great, but I think a similar scheme for audio would be fantastic. With a simple sound.setBuffer(binaryData) you could do a huge amount of interesting things. Sound synthesis, generation. From musical applications, to game sound effects, or just sound notifications within applications. All of this could be done with a minimal impact on filesize. No need for .wav's , mp3's etc.. Sound capture You could capture audio from mic and allow the user to edit it and process it. You could build annotation tools, voice messaging, musical applications etc.. Also if you can get a handle on the audio stream before it hits the audio device you could have live control over streamed audio, tone controls, reverb, delays, echo cancellation, noise reduction. etc.. So, personally I would rather see the components available to us as developers, upon which we can build a variety of applications. MIDI playback being just one particular application of the feature set. Also other similar systems like OSC could be used. anyway, im glad you are asking and i'll happily contribute anything to a document you will put forward requesting audio related capabilities. thanks, Martin Tyler Wright wrote: The Flash Player has evolved through the ages to provide the most needed functionality.

The difficult part of the question is that the circle is really a 3D object ie it can be rotate about the x or y axis. Ie imagine a plain circle drawn on the screen, now imagine your could "push" the top of it down till its was edge on, then the max radius would be half the width of the box. If pushed in on the left till it was edge on it woulde be half the height of the box. But how about all the other angles in between.

you dont 'delay' the return function, just consider that each invocation

the idea is something like this (its not tested code, but hopefully will

also, it assumes that each node has only one child, otherwise you would
need to find multiple paths
function findTransitionPath(node:XMLNode, attributeName:String):Array
{
if(node.childNodes.length == 1)
{
// check children for transition attributes in nodes
var path:Array = findTransitionPath(node.childNodes[0],
attributeName);
}
else
{
// no children, so sub path is empty
path = [];
}
// check this node
if(node.attributes.transition != null)
{
// make this node the start of the array
return [node.attributes.transition].concat(path);
}
else
{
// just return the array from our children
return path;
}
}
there may be better ways to do this... :)

a member variable and work with that instead of subclassing movieclip.

I have an interface called "IMapHolder", and two implementing AS2.0 classes
called "SWFMapHolder" and "ImageMapHolder". Because I'm not sure what type
it will be, I'd like to associate the MC and the class dynamically.
Something like Object.registerClass() would be perfect, but I imagine that
doesn't support AS2.0.
Do I need to create two separate MCs, each with its own linked AS2.0 class?
Or is it possible to dynamically register an MC with AS2.0? Thanks all.

Re: [Flashcoders] Circle, rotation to ?
actually the solution was simpler than i first thought, if you take
advantage of the fact that _rotation can go above 360 and below 0 then
all you need to do is this :
import mx.transitions.Tween;
import mx.transitions.easing.*;
function rotation(dx:Number, dy:Number):Number
{
return Math.atan2(dy, dx) * 180/Math.PI;
}
circle.onRelease = function()
{
var newAngle:Number = rotation(_xmouse - this._x, _ymouse-this._y);
var dist:Number = Math.abs(newAngle - this._rotation);
this._rotation %= 360;
if(dist > 180)
{
if(newAngle > this._rotation)
{
newAngle -= 360;
}
else
{
newAngle += 360;
}
}
new Tween(this, "_rotation", Strong.easeOut, this._rotation,
newAngle, 1, true);
};
//
just mind the formatting.

Hmm yes. Looks like the regular Tween stuff won't work.
Looks like a rotation easing class might be in order. And it decides
whether or not to rotate + or - to get to the destination. Its a bit of
work to do, but it would really be worth it. The Tween class seems to
only want to += until it gets to the desired rotation - which is
understandable. But sometimes we need tighter control ;)

well, what you need to do is work out the shortest route to the angle
you want.
i think it would go something like this
first compute the difference in angles :
angleDiff = abs(destAngle - sourceAngle)
if its greater than 180 degrees, you want to go the other way.
to find that, check which angle is bigger.
goClockwise = sourceAngle > destAngle
So, if you are at 5 degrees and you click at 355 you get :
angleDiff = 355 - 5
= 350
goClockwise = false
and if you are at 355 and want to go to 5
angleDiff = 5 - 355
= 350
goClockwise = true
then find out how far to go :
howFar = 360 - angleDiff
and if you want to go anticlockwise, make it negative
THEN, keep the original angle stored, run the tween from 0 -> howFar
and add it to the original angle at each step.
i think this means you wont be able to get the tween to change
_rotation directly, but rather you'll have to get a callback or
something similar to grab the current tween position. (or you could
do something nifty with nested movieclips and rotate the parent
without tweening first, so you can just modify the rotation of the
child from the tween, but that may be more trouble than its worth..)
anyway, i think that should work, im just working it out as i go
along so it could fail for some cases...this may be where i was
thinking about the quadrant checks, but im not sure.
i'll give it a try in a while, ive got non-computer things to do now. :)

Re: [Flashcoders] Circle, rotation to ?
ok, i was wrong, looks like you dont even need the quadrant

i made a little movie with a circular movie clip, the reg point was in
the middle, and another movieclip called pointer, which is just a line
going up from the reg point, then this code did the trick
circle.onRelease = function()
{
x = this._xmouse;
y = this._ymouse;
angle = Math.atan2(y,x) * (180 / Math.PI);
_root.pointer._rotation = angle + 90;
}
thanks,
i havent written code like that in a long time, its quite fun being old

the quadrant check itself is easy, just check if x is left or right of

click on the circle, now with easing (even just linear), rotate to

Re: [Flashcoders] Debugging wih FAMES?
very true, it also brings up the point that the development of open source tools can (to some extent) now be unified where the eclipse platform is concerned. If a developer creates a nice plugin for flash development on eclipse, a developer who is using either FB2 or a collection of open source alternatives can benefit. I agree, i think its a very good move. martin With Flex Builder 2 being built on the Eclipse platform, there is enormous scope for open source developers to contribute very low level functionality to extend and enhance the product. You really do get the best of both worlds and I, for one, applaud Macromedia for choosing it.

Re: [Flashcoders] Debugging wih FAMES?
i'll combine my answer to jesse with a response to this as well, because they cover some of the same ground..hope you dont mind. why choose open source vs flexbuilder 2 ? because A: its open source, if it doesnt do what i want, there is always the possibility to change that B: it would most likely be free. Now, im not averse to paying for tools which i use and would consider buying FlexBuilder2 if my work required it, but its not just about me. of course, its too early to say if MM will make the command line version of the compiler available for free. If they do, then thats great, that alleviates some of the need for an open source / free version, and it would allow me to concentrate more on working with the ASDT team to make a better development environment. If their compiler is not free, then we'll see what direction the osflash community moves, if its towards an ocaml based compiler, then i'll learn ocaml, if its towards an antlr / flex / bison based approach then i'll help with that (and there has already been work on an as3 antlr grammar, so the pieces are starting to take shape) whatever happens im determined that a free compiler should be available, because it would keep the momentum around osflash going. If the only option is to buy FlexBuilder2 then I think the (OS) flash community would start to lose out on potential development talent that would be attracted. In my opinion the scope and quantity of tools that will be created to support flash development would be severely hindered by the lack of a decent free compiler. just to be clear, its not about one versus the other, its about the whole flash development ecosystem. Having commercial tools with commercial support is very important within certain sectors of industry, and similarly having free versions is important to other sectors of industry. with both we have choice, with just one, we dont. i like choice. thanks, Martin.

What I'm wondering is the doing something timeconsuming part - I need a
simple operation that will be reasonably consistent across player types - is
there any operation that *hasn't* been improved or that has always been
fast? The target player is FP6 (pre 6.65), so I need an operation that will
be consistently slow or fast on every player since then
Has anyone done this much?

[Flashcoders] Scope Issues was :Newbie AS3 question
In my opinion this problem comes up so often because of bad design in the libraries. If the libraries were written to support the observer pattern rather than all this anonymous function / function binding the world would be a better place, ok, the technique itself is useful and slightly more compact than observer, but its very confusing at first. I guess it was an inevitable side effect of the transition from AS1 to AS2 without any change in the underlying model. anyway, lets not get too excited, if someone knows of a good article that explains this clearly with good examples, please post the link and i'll make a reference to it from the flashcoders faq section on the osflash wiki. http://osflash.org/flashcoders/as2 thanks, Martin ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] Re: Newbie AS3 question
ryanm wrote: The idea is to use it (this) when you have two variables with the same name, usually to distinguish between the class member and a locally declared variable. You must know that :) The compiler won't know to use "this" or not in those cases, so it is important to use it in those contexts. Actually, the compiler *does* know, it always adds "this." to references without explicitly stated scope. Which brings us full circle, all the way back to maintainability. Now, if you have a class, and all of the member functions and variables are referenceless (using "assumed" scope without the this reference), and all of a sudden, in the middle of a method, you have a this reference because of a potential scope conflict, what does a developer looking at your code 2 years after you've left the job think about it? Does he remove the single this reference, to make it more readable and consistent, thus breaking the method and blowing up the whole project, all without knowing how or why? Martin piped up with "I would refactor the method to make it more readable..." immediately, which, in this case, would've broken the method (if he removed the reference) and possibly the whole class, which is exactly how these sort of expensive, time consuming, and difficult to troubleshoot problems come up. On the other hand, if the original developer used the this reference every time, it would already be consistent, readable, and explicit about scope. The other question is, would Martin (not to pick on Martin, but he was vocal about it, so I use him as an example) take a class that stated scope explicitly and remove all the this references, possibly breaking the class in the process? It sounds like it, from his post. The question is, is that a good practice or a bad practice, and does that make him a "good" developer, or a "bad" one, given the potential for expensive and time consuming breakage caused solely by his dislike for the keyword this? Its ok, you can pick on me, i dont mind ;) I'll take each piece seperately. 1. Removing the single 'this' reference. well no, i wouldnt remove it because i know why its there. If the method was long and could / should be refactored, then that is what i would do. Of course there exists edge cases where that isnt feasible, but most programs dont implement DES algorithms (to relate this to an earlier post) and a lot of legacy code i have worked with has benefitted from being re-factored. If i see one 'this' reference among a series of unspecified local references then I would look at it carefully and think that the programmer had good cause to specify the scope in that case. One 'this' reference doesnt have much of an impact on readability but using it everywhere does, as Jesse highlighted. I would rarely advocate becoming dogmatic about any technique, *always* do this or *always* do that, because its not often an all or nothing decision. Of course, in some far off dreamland this code would also have unit tests so that if i did refactor it or unthinkingly removed the one reference to 'this' then a nice little red bar would tell me id done something bad, but again, im realistic, most code doesnt have unit tests. :) 2. Removing all references to 'this' in supplied code. It really depends on the level of maintenance im expected to undertake with the legacy code. If it was just a minor bugfix or two, or some tweak then i would be inclined to save myself the effort and just do what is required (i.e. leave the extraneous references to 'this' intact). If the code required some major work then I would remove the references to this, except where necessary. Like i stated in my first post about this subject, sometimes its necessary and i know when that is. Most of the time it isnt and personally i feel that it clutters the code. One more thing worth mentioning, and I don't say this to be rude or as a slight to anyone on this list, but the opinion that the this reference is bad and should be avoided seems to be unilaterally coming from people who learned programming in Flash, while the opinion that scope should be stated explicitly seems to be coming from people with more formal training in software development and experience in (non-Flash) real world development. Personally, I have to give more weight to the opinions of people with more formal training and more varied real-world experience, because there are some things you just can't learn in a year or two of using Flash for web development. Unless you are a mind reader or have access to information about each poster that is in this discussion then i would say that its a dangerous and false generalization. I initially learnt my programming way back in the mists of time, before flash was but a glint in some guys eye, and have had my fair share of formal training and developed in non-flash 'real world situations', but in my opinion that isnt really relev

The fundamental concept that you seem to miss is that "addChild"

the context is the current class. Occasionally 'this' is useful if

in my opinion putting 'this' in everywhere to me just makes things

ryanm wrote: What I don't get is why it needs "this.addChild" instead of just addChild. I've been sick of the keyword "this" for a long time and have since avoided it in AS2. Any reason that it needs to be back in for AS3? Maybe because it's one of the most useful scope references ever invented? The fundamental concept that you seem to miss is that "addChild" is meaningless by itself, it is a method of an object (in proper OOP development), and if you just say "addChild", who is adding the child? the context is the current class. Occasionally 'this' is useful if you happen to name a method parameter or local variable the same as a member variable and need to distinguish the two. But, I dont agree that its bad form to leave it out, nor is it any more difficult to maintain. in my opinion putting 'this' in everywhere to me just makes things harder to read. thanks, Martin ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Re: [Flashcoders] Flash vs Flex
well, if you want to have a stab at it, it would make a great addition to the current set of open source tools used for developing flash content. head over to osflash.org and get involved :) im sure theres others around who would be interested in helping develop something like this...i know i would take a keen interest.

Re: [Flashcoders] Macromedia unveiling Flex 2andFlash9 :communication or cacophony ?
(except for the fact that they seem to be trying to kill open source remoting... damn cant they just compete on features!) Hank, i really dont think this is true. if you check the new docs you'll see that AMF is still in the new player, BUT there is a new version of AMF (AMF3) which contains improvements to the protocol. and like the old and new VM, the two AMF protocols can exist happily side by side in the the new player. thats how it seems to me anyway. thanks, martin ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] > Normalizing point
you can also combine that with some curve smoothing Once you have 3 points you can calculate the angle between the first and the third and use a tolerance (some call it the 'breaking angle') to determine if the middle point can be removed from the data set. so one idea could be to use 1 distance threshold and 1 angle threshold 0 -> DT : very small distance, just remove the intermediate points. > DT : check the change in angles of line sections and remove those that are under AT (the breaking angle). This would get rid of straight and nearly straight lines with multiple points. of course you could expand on this and make AT inversely proportionate to the distance between points, so that as the distance between points increases you break at a smaller angle. this could be done either as you store them or as a post processing step. hope that gives you some ideas. martin. Hans Wichman wrote: Hi, how about doing this while storing them? You know the last point stored, every time u get a mouse event and are ready to store the next point, u calculate the distance from the last point first, and only store the new point if the distance is bigger than a certain value. greetz Hans ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Referencing MovieClip
if the methods are in the same class, then that should work, assuming
that the reference to timeline is still valid, try trace(timeline) to
make sure.
alternatively, you could store the movieclip references in an array and
then access that later rather than getting them from their parent movieclip.

Probably a bit of newbie question but here goes:
In a class method I'm creating a movieclip (this is simplified)
Public function whatever(timeline) {
Var mc:MovieClip;
For (var j = 0; j < someVariable; j++) {
Mc = timeline.createEmptyMovieClip("face" + j,
j);
}
}
then later, in another method I'm getting hold of that movieclip again
and doing something with it:
public function whatever_again() {
var mc:MovieClip;
for (var j = 0; j < someVariable; j++) {
mc = timeline["face" + j];
}
}
but the trace gives the value of mc in the second method as 'undefined'
- I can't seem to grab hold of those movieclips created in the first
method.
