Re: [Flashcoders] Getting at SampleDataEvent bytes before full Chunk is reported.
No replies? Okay then. As the player doesn't seem to send the data unless it has a full 2^n chunk within a given timeframe, and also considering that as there doesn't seem to just grab the currently buffered bytes, then I guess it just isn't possible in this version of the player. This is really sad; for, imho, the developer should be able to at least state the minimum sample size he wants reported per sample data event, and not just the rate per second. In combination with mic.rate = 44, being able to set something the minimum buffer amount to be reported, and to set no delays would be perfect e.g. mic.sampleBufferMin = 9; // 2^8 = 256 , must be value between 8 and etc... mic.reportImmediately = true; //to avoid having to wait until the next frame is collected if it couldn't collect enough to report in time or even being able to access the bytes already in the buffer without having to wait until SampleDataEvent is allowed to fire e.g. myByteArray = mic.pollBuffer(); Up until now, I really didn't care about things like latency, as I was merely attempting to learn algorithms for post processing related tasks; yet, now that I have become interested in realtime tasks, it's becoming an issue.

Re: [Flashcoders] is there a dsp lib with analysis using zero crossing in as3
Oh, I also wanted to mention that over the weekend(thanks to wikipedia) I tried a simple AMDF style approach; it seems it would be great for very basic live tuning apps, but it does appear Gerry is correct that it may lead to issues if used for anything else. I also know, from what I have read, that autoCorrelation is used for things like keeping a vocalist in tune, or producing Cher/Akon style effects via the auto-tune vst plugin, so I am wondering if it can be computed quite quickly? or if it is better for non-time-sensitive analysis of pre-recorded data?

Re: [Flashcoders] What is up with adobes documentation?
Personally I find searching google almost always gives me what I want as long as I use quotation marks around a key phrase, and I must agree that Google's results are not Adobe's fault. To talk about the state of Adobe documentation, I must say that I do find it lacking substance in many key areas; however, it is far better than what I have seen from many other companies. If I had to gripe, I would gripe about the stupid community help interface that, more often than not, gives double scroll bar screw-ups, and even though you select local only, searches the web, unless you go into the settings. Buggy to say the least, and it is quite the memory hog too.

Re: [Flashcoders] RegExp Help
Hi Karim and Ktu, Below is an explanation of what appears to be going on in the given pattern: (?:\s*) is a greedy non-capturing group of whitespace (?=[-|/]) is looking behind the next section of the expression, (?name\w*), for, what is in this case, a character set; as well, it does so without including it in the result. In this case the character set could also be written without the |, resulting in [-/] (?name\w*) is looking for name\w*, before the next expression [:|=] you may have wanted (?Pname\w*) [:|=] is a character set : or =, but again does not need the |, and could be [:=] or something like (?::|=) (((?value.*?)(?!\\))|(?value[\w]*)) is what I think you may have wanted to be an alternation, and in another language it would have worked; however, not in AS3. Apparently in AS3 in order to distinguish the syntax from a lookbehind ? you need to use the syntax ?PdesiredGroupName when defining a named group; as well, it is due to the fact that, as far as I know, in AS3 you cannot use names of the same group even a logical OR alternation.

Sorry, for not getting back to you sooner Thank you Gerry, what you said made perfect sense, and you were 100% right; for, the xlr input was in fact on the right channel. However, although you were right, to me this was strange since, because at the flick of a switch, the Tascam US-144 is supposed to, and with every other audio app does, take the stereo input and convert it to mono channel audio without restricting which inputs must be used.

Re: [Flashcoders] Re: Help with Image Slideshow - displaying random image (Anthony Pace)
OOPS...thank goodness I re-read my last post... realized I screwed up,
because the first version I made should actually modify your original
xml. Wow, sometimes I wish this was like a web Forum and you could
just click edit.
I had used XMLList, when it should have been new XML, and you should be
sending in the imgList.IMAGE section. As well, in addition the quick
fix, I updated the code to show the different method that makes a
randomized Typed Array (otherwise known as a vector) that points to the
index locations in the original xml. Don't hesitate to tell me if I
screwed up again.

[Flashcoders] core Math functions in flash vs the browser
Why are the implementations of Sin and Cos s slow? Even a very basic MacLauren series can trump the Flash's current Math.cos or Math.sin, and that is when they wrapped in function calls. Although the rendering performance is poor in the browser, if you try comparing the ff3.5 or chrome's ability to process the the Math.sin and Math.cos calls, you will see vast differences. What gives with the dudes at Adobe? Why was this problem not a concern, nor improved upon years ago? I hear things will be different in 10.2; however, I haven't played with it yet, and I would not be able to comment. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Problems when converting to Number
Oh well, after reading a couple of articles, I think I have confirmed my
suspicion; for, as I thought, it just comes down to there being too many
digits, and the floating point implementation doing some hidden
weirdness. It really sucks that you can really only expect about 15
digits of true accuracy from the Number Data type.
If I am wrong let me know.

Re: [Flashcoders] Problems when converting to Number
Thanks for the response. Right as you were posting, I was posting my
own message of how I read up on the spec, and saw the same thing.
From what I have read, as you can't actually have the int portion be 9
999 999 999 999 999, because its limit is 9,007,199,254,740,992 , you
can really only trust the use of Number up to 15 digits of accuracy.
Let me know if I am wrong.

You're getting to the limits of the precision of a Number.
In ActionScript 3, the Number type is stored in binary, in 64-bit
double-precision IEEE floating point format:
http://en.wikipedia.org/wiki/Binary64
It uses 52 bits for the mantissa (fractional part) which gives it an effective
precision of 53 bits, equal to about 16 decimal digits of precision. The error
you're getting is in the 17th digit - no surprise at all.

1/32, and so on. You can create numbers that aren't multiples of two by
adding multiple digits. For example, 1/4 + 1/8 = 3/8, or .375.
This works pretty well, until you get numbers with a lot of decimal places.
At some point, you will find a decimal that is impossible to make using
powers of 2.

Can anyone tell me why I get this weird result in output window?
As people have said, it's a problem with decimals. It's not a problem
with
Flash--it's a problem with binary numbers.
Integers are accurate because all integers are a multiple of 1, and
binary
does just fine with combining 0's and 1's, the only possibile values
of a
digit in the binary system.
If you think of decimals as fractions, maybe it will help you
understand the
issue. In binary, a digit can only be a multiple of 2: 1/2, 1/4, 1/8/
1/16,
1/32, and so on. You can create numbers that aren't multiples of two by
adding multiple digits. For example, 1/4 + 1/8 = 3/8, or .375.
This works pretty well, until you get numbers with a lot of decimal
places.
At some point, you will find a decimal that is impossible to make using
powers of 2.
Cordially,
Kerry Thompson

Re: [Flashcoders] How to detect for modifier (alt/ctrl) keys
Just thinking out loud, but I took a look at the code and I am wondering
if this would this not be better implemented as a singleton?

Simplified test code:

When I test the code (tested on 2 PC's with Flash 10 or 10.1 Debug
player in
Flash pro CS5 or via same version debug players in MSIE/FF browsers) and
press only the right alt key or a key combi e.g. right-alt-5 the traces
report always true for the ctrlKey, so even when it isn't pressed!?
I checked the Adobe bug base, tried Google, but didn't find anything
related
so far.
What am I missing?

Re: [Flashcoders] Inheritance and abstract classes
Well, although it is good to know the accepted lingo, and although I
must say Juan's post was an enjoyable read, I do have to say that it
supports my point, and Jason's post illustrated exactly what I was saying.
(...continuing my IMove example, which was most definitely not as clear,
but is what you were describing with your collision detection example)
I believe an interfaces only real usefulness is in the ability to make
sure it conforms without having to a bunch of checks. Because you could
have thousands of different animals, like cat, dog, human, etc., but
unless using * as the type
e.g.
makeItJump (obj:*){/*code to test if it can jump goes here, and then
code to make it jump*/}
makeItRun(obj:*){/*code to test if it can run goes here, and then code
to make it run*/}
and then checking that the object was in a list of objects allowed to
use makeItJump, or testing if the passed object had the required
methods, it can only type check against one type at a time; yet, an
interface can allow all animals that have the IMoveable interface cat,
dog, human, rodent, etc.. without having all that code
e.g.
makeItJump(obj:IMove){/*code to make it jump goes here*/}
makeItRun(obj:IMove){/*code to make it run goes here*/}
which, is obviously better; yet, by just looking at it, it seems that it
should be has-a, because you are testing if it has the capability to do
something, or has-a given interface. Therefore, considering you are
essentially asking if it's capable, I think the logic for the accepted
lingo is screwy.
Unless you are just trying to get across that it is-an object that is
movable, I still think that the usage of is-a has-a as descriptions is
non-sense.
I-am Anthony
Anthony is-a Human
Anthony has-a voice because he implements the voicebox interface
But Anthony just has to be difficult and different, so please excuse him.

Re: [Flashcoders] pdf encoders
Hi Guys, Thanks for the suggestions. Right now as I have a limited time, I am authenticating the users, grabbing the data from mysql, outputting it as SVG and HTML, and then converting it to pdf, I have decided to continue using TCPDF. After a few revisions most of the bugs I have complained about were fixed, and I have created custom (hackish) workarounds for those that would just take too long to wait for. In addition to the bug fixes, after a few server reconfigurations, including increasing available memory and allotted processing power, everything is working quite well. It's only a few thousand PDFs in total per run, plus what the Reps and clients will be having generated on demand, so a few server instances running simultaneously can take care of that in very little time. OT: As the client uses illustrator (I told them they should look into inkscape), I also found a bug with Illustrator's SVG import/export features too and reported it to Adobe; yet, even though this is a simple bug to fix, I am not holding my breath to hear back from their devs. It is funny that one guy can fix tons of bugs; yet, a team at Adobe won't fix it, even if it's a security issue, for months. Open source rocks. I am going to donate a little to the TCPDF project cause the guy has been so amazing.

[Flashcoders] pdf encoders
I am sending this here just cause I think it's likely some developers here have had to work with PDF output. I know about alivePDF, which is great; yet, from what I have it's just not ideal for generating hundreds of PDF files in a row right now. For several PDFs here or there, alivePDF would be okay; however, I need at least dozens per minute, plus some security to limit users, so something on the server side would be best. Does it even have user security features? (e.g. encryption, or no printing at a dpi higher than specified) I know they can be bypassed, but I am not trying to make it impossible; just not practical. I know I already mentioned TCPDF (offshoot of fpdf); however, I need something really stable and really fast, which tcpdf, although feature rich, just isn't. I do have to say, that when I submit a bug report to Nicola Asuni, the guy that does most of the development, it gets fixed in a couple days; yet, there are just too many at this point, and the speed is so slow, that it just won't work for my needs. Any suggestions? Oh yes, I need it to be opensource, and the client is not interested in paying a license; therefore, PDFlib is out of the question. Maybe, something in Perl if it's really easy to use? But, I would prefer PHP; cause it would integrate better with everything else I have done.

Re: [Flashcoders] Baby Step #2
I was looking through a specific response to a question I'd asked in the past, when I saw that I hadn't noticed your statements. Although it may appear stupid to reply now, considering that I have just read the message, I will still try. Most of the grant money for University level RD, comes from the people, through tax dollars, donations, and student tuition; therefore, I ask you, why should the people pay a second time, and possibly be forced into the poorhouse, in order to have the privilege of being educated? Why should education not be free or, at the very least, affordable? Your stance seems to suggest that charging for access to information on a sliding scale based on quality, as a means of stimulating the economy, is not only a positive notion, but the only notion that could possibly work; yet, I suggest that their are tax dollars which could be better put to use funding NFP publishing companies that can disseminate information freely or cheaply. In a properly run NFP publishing house, that has a decent amount of funding, the designers, copy editors, and authors that you mentioned can all be compensated. (before you suggest that funding would be impossible, think about various web models first) As well, in addition to most of the important people you mentioned still being employed and in the loop under an NFP umbrella, providing free access to information can actually help stimulate the economy, and allow for a more even distribution of wealth; for, it provides those, that would not normally be able to afford access to information, an avenue of possibility for competing effectively with the rich. Okay, so you may never agree with my viewpoints about free access to information and education, 'cause you may very well have money; however, I am sure that most of the 77.72 % of High-school graduates, eligible to attend college but unable to progress due to financial reasons, would tend to have opinions in line with my own. With regard to the profit from and satisfaction + delivery to the market... You say there isn't a market; therefore, I suggest, considering you claims that the costs of production and printing are so high, that different avenues of distribution be found, and that the companies that publish start to make efforts to actually develop a market for their materials. I must also put toward you the question, if there is so little profit to be made, then why do they continue? from my perspective, considering my Aunt owns a publishing house in Scotland, it is due to the fact that although the Author may not see a ton of the profit, those in distribution do. A great many books that provide small profits, end up equalling to a gigantic profit overall; therefore, a cost reduction to enhance sales over the long term is possible, but is absolutely undesirable in the short term. I am not saying that the costs should be reduced to unlivable standards, and not to the point where competition drives the delivery of a poor product; yet, I am suggesting that the costs for the consumer can, and should, be reduced to affordable levels while keeping quality high. Large publishing houses, could use some of that stored capital toward publishing a more vast amount of materials at the same time, because although the profits will not be as large, the costs as long as quality is kept high, will be offset by the fact, again, that a large amount of small profits put together equal a large profit overall. I must also state that, from experience, the better the quality and lower the cost of the product you provide, the less support calls you need to take, and the less money required to be put toward customer support. Right now I manage a small business that is competing quite effectively in a highly saturated market, specifically because we chose to reduce the costs for the consumer while at the same time increasing the quality of service; therefore, I know what I suggest is possible, especially since the concepts are not new, extremely basic, and very easy to implement. Now, before I am done my rant, I must again state I have not stolen a book, because I am a great fan of going to libraries, in person or online, and of purchasing materials that I need to use consistently (goes for software too, because the coders I know work bloody hard); yet, I can most definitely turn a blind eye to others doing it when I feel the company is gouging the consumer. Anthony P.S. 30hrs max allowed at most chains in Canada as a means to avoiding additional health insurance costs to the company, multiplied by $10.25 our new minimum wage in Ontario, is equal to $13,543.53 after tax... in other words your flipping burgers statement is BS, and I would love it if people with money would stop spouting this nonsense.

Re: [Flashcoders] If a URL starts with “http: //” will clip always be loaded into REM OTE sandbox?
Oops... Geeze...sorry... realized you were talking about swf files and not images...posted this after working for 43 hours straight. For images it is just using javascript and canvas to grab Pixel info from your image, and then send it to flash using ExternalInterface. In your case, with an swf, you could just download the file to a webserver with a crossdomain policy file allowing you access, and then serve it up once it is completely downloaded.

Re: [Flashcoders] External Interface with looped parameters
What you are suggesting, is almost the same as I suggested, except that
you are avoiding the xml object and instead using a string; however,
because of how a string is converted when passing the data, I wouldn't
recommend it for anything too complex.

I have:

number of parameters I receive from the XML.
I want to pass it to javascript like this:
ExternalInterface.call('jsFunc', objs[0], objs[1], objs[2], …);
so that the JS can use whatever params are provided.
I realise now however, that passing an Array (or name-value pairs) is
a far more stream-lined method of achieving this, but I'm still
curious if I could in fact build a function in a loop and then call it
after. Interpretive languages could possibly handle this real easily,
but is there an interesting workaround?
Maybe something like:
var st:String = function() { jsFunc(;
for each(var i:String in objs)
{
st += i+, ;
}
st+=);;
ExternalInterface.call(st);
It's reaching for stupidity because I lose the beautiful automatic
Array conversion that AS3 does, but curiosity has the better of me at
the moment.

Re: [Flashcoders] Blocking multiple logins on one computer
You can prevent more that one login at the same time for the same account; yet, you always have to consider an MITM attack being possible unless you have a known pre-shared key system. In your DB, all you need to do is keep track of how many users on a given network are connected, or attempting to connect on that login. There is no way to prevent multiple logins from users that have different accounts, 100% of the time; for, IP addresses get shared, NAT is imperfect, MACs + IPs can be spoofed, and even if your ISP adds identifying elements to your packets, a proxy-per-browser can fool you almost every time. On some types of servers, you may want to leverage statistics about user interactions with other users and the system, to see if identifying patterns emerge; yet, this would all depend on the stats you track and your ability to develop learning and pattern recognition systems. This method is great for monitoring systems for gaming, management, communications, and financial institutions, and can be extended to many other areas; however, you really do need to know what data to track, and how to use it, and even if you do, I could easily just modify behaviour slightly enough to outsmart the patterns it can recognize. There is also the method of having someone sit and moderate user interaction, to see if someone is using multiple accounts or trying to screw with the system, and then enter in variables that made the moderator flag the interaction as being unsafe so the server can use it to eventually do it automatically; yet, you would need to know how to implement a system that can modify the patterns it looks for, if it notices it has become too strict. Sorry about the rant, but I just want to get across that no matter how technical you get, there is no perfect method, and you can't do much about it, unless you really filter out who can have an account, and what information that account is associated with. E.G. banks force users to provide id, and there is no way, unless they specifically allow it, or fraud was used to gain an additional account, that a person could have two accounts and be logged into them at the same time.

Re: [Flashcoders] Strange RegExp behaviour
Johnathan:
if there are 6 items on the stage, numChildren = 6 but to access the
6th item you need to be at position [5] of the array, so for ease of
implementation he used:
this.numChildren-1
My test showed that it if he has some screwed up object that does not
match his regex, it will not show, so that is why it shaved one off when
tracing. It still went through the entire array, it just chose not to
output what it didn't like.
I would also like to point out that I changed the loop conditional
expression to see if the counter childnum!=-1 , meaning that if there
were 6 items on the stage, that position 5, 4, 3, 2, 1, and 0 would be
checked, but it would not go further.
So again, the code I tested does work fine, and if you want to be sure,
you can even trace out the childnum value before or after the if
statement in the loop, to see how far it goes.

Re: [Flashcoders] Recursive:Part II
Jason beat me to the punch on this one, but, I was going to say too, in
all seriousness that this doesn't work if each child has two parents; as
well, having step parents is another ball game too.
Take for example if a person has 6 kids with another person, than in
your model, each person, would have to have 6 kids underneath them, and
that would duplicate a ton of data, which with regard to bandwidth
concerns can be a problem when you are breaking down a family tree.
Just imagine a scenario where my six kids, each have six kids, that have
six kids, but now you have to duplicate that under the second parents,
and you will see what I mean.
The best way to do this for two parents, is to have each person be an
individual, and give them a motherId and fatherID.
If there are no IDs it's an orphan, and the start of a new tree.

.etc.
Also, recursive functions call themselves - and then break when some
value or condition is reached for yours, add to your object, and
then check to see if there are child nodes in the xml below it, if so,
call the function again to add more, if not, break out of the function.
However, this will only get you through the top level nodes and one of
the top level nodes's sub nodes - not the others - I actually can't
think of how to get into the OTHER sub-nodes - though I know there are
people on this list who do. I know what some people do is make the first
pass on the first level, then the second pass on the second, and so on,
adding to the object as they go. Don't ask me to send you an example
though.
Recursive functions are also quite hard to wrap your head around. :)

first names. I am trying:
createPeople(peopleXML)
function createPeople (_xml:*):void
{
var xmlList:XMLList-_xml.children();
for each (var fn_xml in xmlList) {
createChart(fn_xml);
trace(item_xml);
}
}
I am wondering - am I on the right track? Does the xml look well-formed
for doing what I am trying to do?
Thanks!

Re: [Flashcoders] Bezier curve arrows
Hi Pual, I just noticed that I had already written something, but it didn't get sent to the list before the question got answered. Oh well...anyways: To find the angle, you have to find the slope of the tangent at that point of the curve; however, this is really easy because with bezier curves you already know the tangents for the end points. the control points for the cage of a bezier are: A(the beginning point that you will be curving from) B(the middle) C(the end point you curved to) the slope of the line AtoB is the slope of the tangent for point A the slope of the line BtoC is the slope of the tangent for point C remember that the slope, m = deltaY/DeltaX, rise over run, (y1-y0)/(x1-x0) Now that you have the slope for each line segment, and since m = tan (theta), then arc tan (m) = theta; therefore, pop in the slope, using Math.atan(m) to get the radian, or Math.atan(m) * 180 /Math.PI to get the degree. You could also use atan2 reducing points by offset, but either way you need to use the ctrl points. Now that you have the degree, if your arrow head are dynamically generated you know how what to translate the points by; however, if they are shapes than with the registration point located at the arrow head tip, then rotating should be a piece of cake from that point.

[Flashcoders] faster work flows?
I currently use a few methods based on who I am working with or if I am on my own 0.pure timeline based animation with some simple scripting 1.Positioning by code of imported assets, after taking all x,y data from illustrator or flash (one frame or no frames because I am using flashdevelop or the flex IDE) (I wanted to work with catalyst, but it is proving not to be all that useful right now; thus, I am toying with the idea of making my own basic tool to do something similar for simple code gen purposes. I have heard a lot of hardcore pros talk about how they did this, so I am hoping it will work out for me.) 2.frames on the timeline using the flash IDE to position assets; yet, this makes doing transitions between frames more difficult. Is there a faster way? Right now everything seems so tedious. Time I should be coding is being spent working with the design to figure out x,y, so everything is pixel perfect.

Re: [Flashcoders] Fwd: Dynamically superimposing image onto video
If you don't mind your stream being downloaded without the required branding or possible news event embedded into the video, plus the added bandwidth overhead is not a concern, than an overlay is perfect. If there are branding concerns, or you work for a site that would like to reduce bandwidth and send news events cnn style, then you will have to know how to modify the stream before you send it to the client. If new events aren't required, but the branding is, then you really only need to do a separate encoding that includes the content.

Re: [Flashcoders] Fwd: Dynamically superimposing image onto video
For the first sentence I meant to say that applying an overlay at the client is fine, if you are not concerned with your stream being ripped without branding, possible cnn style news events, or captions being included. If things need to be live and targeted you will want to do things at the server; otherwise, if server load is a concern, and you do not need to be changing graphics live, then doing it during encoding and prior to uploading the content to the server might be the way to go.

which child object the mouse is hovering over/clicking etc...
What is the fastest way to do this?

Re: [Flashcoders] Little direction please
No lists I know of; yet, I haven't done any searching. I taught myself the advanced aspects of JS in about a week or so of trying things out, so I am sure that anyone with even a little ActionScript 1/2/3, experience can pick it up really really fast. I was going to write a hundred helpful tips (tag renewal issues, dynamic objects as complete containers, arrays as objects as arrays, custom event handling, cross browser issues, Function scope, Prototype programming, optimization, etc...); yet, I realized you may just want to check out the Douglas Crockford vids, read his book, and check out his site. The play-list has the videos I am referring to and a lot more; yet, they are not in order, so I suggest watching, from beginning to end: 1: the javascript programming language 4 parts 2: advanced javascript 3 parts 3: theory of the DOM 3 parts 4: what ever else is available on the topic http://video.yahoo.com/playlist/100205936 If you can find a different source for the videos, I would, because you may want to go back and forth, and sometimes the streaming stalls, forcing you have to reload starting from the beginning again arrrgh. the books he recommends: http://www.amazon.ca/gp/search?index=bookslinkCode=qskeywords=0596101996 http://www.amazon.com/exec/obidos/ASIN/0596517742/wrrrldwideweb his site: http://www.crockford.com/javascript/ On 2/27/2010 12:48 AM, Karl DeSaulniers wrote: Hello, I am not sure if this is a cross post, if it is, I do apologize.

Re: [Flashcoders] MultiLevel ContextMenu
Javascript to as3 combo, as suggested below, would work; yet, not in Opera (anyone care?) , and not very successfully, at least during my experimentation, in browsers running in on top of *nix OS (I kind of care about this one). You can also check out the link below, as it is now integrated into Adobe Captivate; however, last time I looked at it in 2007, it was a bit limited and you may want to roll your own. http://uza.lt/rightclick/ http://code.google.com/p/custom-context-menu/ I eventually used something very similar with my own event handling code that is a little more to my tastes + more customizable; yet, at the very least it is a great place to start from. On 2/19/2010 6:33 AM, Benny wrote: Flash doesn't support that or actually even prevents us to come up with a custom context menu.. In the past some flashers worked around that limitation by capturing the right click mouse event in javascript and then communicate the event via a local connection to the flash movie which than could built a custom context menu. This worked not in all browsers though as far as I can remember.

Re: [Flashcoders] and now..CLIENT now hates Flash
I think it has very little, if at all, to do with Apple wanting Adobe to produce a better product, and more to do with licensing fees, and revenue from app store purchases. There would be a lot of lost revenue from the app store if you could just put flash on your device and play a game downloaded off the web for free from a plug-in that passed along the capacitance and accelerometer data to the swf. On 2/4/2010 10:47 AM, Gregory Boudreaux wrote: Also Flash is playing a bigger role in corporate eLearning, especially after Adobe ended support for Authorware... and all the third party development tools that publish .swfs. In addition to Adobe Connect with its presentations and virtual classroom features. My personal opinion is that Jobs is trying to push Adobe to fix whatever problems he feels the Flash Player has on the Mac and get it to a state where he feels they can do business. He is playing this out in the public arena so that he can build up some support and maybe make Adobe speed things up a bit. With the emergence of Google in the mobile device market, Apple will need to step it up to stay on top the mountain... and I think one of those things will be to have the Flash Player on Apple mobile devices. It will be this big announcement and everyone will think it is the greatest thing since the iPhone. gregb ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] WIRED hates Flash
Angela: That is a great suggestion. Normally a client will ask for detection, but some will opt to allow the user to choose which version as browsers false report and failing gracefully doesn't always work. eg. Which version (plain html with javascript employing hacks to make it work with each browser, or fun and flashy)? So in this case, why not state something similar to what Angela suggested? if they choose flash, give a link to Apples complaint e-mail and government consumer affair websites where users can publicly register complaints.

Re: [Flashcoders] Still Infinitely Looping
In addition to my last post, I would like to state that you shouldn't
timeline; it has its place. The flash IDE is great for making things
pretty, and doing really quick experiments; as well, it forces you to
work off of memory for some things that would normally just be presented
to you in other IDEs. No doubt about it, flashdevelop is my favorite
ide, and it is free too; yet, Flash is indispensable if you want to make
great looking websites, like you have stated, on any kind of decent
timeline.
A couple of other things to note about your code...
Where is you mcHand class coming from? Why haven't you imported it?
even if it is in the same folder ait's kind of lazy and hard to
understand when you exclude it from the import statements; however,
since it is done automatically, than it is a style thing I guess.
You have already imported com.greensock.* which imports everything, so
unless there is something weird going on, you can take out the other
greensock import statements.
(OT why oh why they put the com in front is beyond me, as no matter
what you will still have the same amount of folders if you do it the
other way? and I especially think it is stupid, because a lot of
communications classes are called com and not just net. )
Take care,

Re: [Flashcoders] Baby Step #2
If you want them really cheap, get a library card. I have one through university, but a library card through the Toronto public library, and most public libraries, give the general public access to a wide array of material, and to a safari books online login, for free. With safari books online and my library cards in hand, I haven't had to pay for a programming/math book in ages; however, you could argue that since I pay taxes, it is not absolutely free. e.g. Every Keith Peters or Colin Mook book is available through safari, videos like the entire lost actionscript 3 weekend video set(a bit basic but none the less nifty to watch), tons of the friends of ed, sam, idiots guide, head first books and more. The only book I have not been able to find is a good book on math with regard to music/colour theory, so I am contemplating shelling out. I could probably download a pirated copy of every book I read; yet, for now, I am satisfied with the access my library cards give me, and happy to shell out a little money for a great book that I want in a tangible format on my desk. The only books I don't feel guilty about people ripping, are the ones that I have seen cost $180 - $390 or more per book. (e.g. advanced computer engineering, physics topics, biomed, journals, or graduate level anything). beno - wrote: On Fri, Nov 20, 2009 at 2:48 PM, jared stanley jared.stan...@gmail.comwrote: FYI i've had luck getting most of the latest flash books on amazon used for $5-20 each.

Re: [Flashcoders] Placing sprites on the circumference of a circle
it depends on your registration point for each clip. If it is at the bottom centre, than just set the x and y have it be rotated by degree - 90 W.R. de Boer wrote: Hello, I am currently working on a little flash project where I would like to place the sprites or elements on the line or circumference of a circle. Now I know how I can get x,y-position of each sprite using the cosinus and sinus functions together with the radius and angle. Only the problem I am currently experiencing is the putting the sprites nicely on the line of the circle. It's some rotation related thing but I don't get it. The basic idea is to have an earth and then all kind of items such as buildings to be positioned on the line/circumference of the circle and then follow the form of the circle. I only don't get it. I know I can get the x,y position for these (building) sprites the following way: var radius: Number = 50; var angle: Number = 60; var x: Number = Math.sin(Math.PI/180 * angle) * radius; var y: Number = Math.cos(Math.PI/180 * angle) * radius; Now I only have the problem to nicely rotate the sprite in such manner is basically following the form of the circle. I have made a drawing of how the sprites and/or buildings (every rectangle is a sprite) should be placed on the circle [1] but I don't know how i get that nice rotation calculated. Anyone having any idea how to do this? Too bad, they didn't discuss this during math class :( [1] http://i35.tinypic.com/2a7daop.jpg Weyert ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] visually similar spectrum
After doing a little reading, I think, but I don't know for sure, that what I am referring to is called HVS(human visual system) compression. Any books, detailed articles, formulas or code? Henrik Andersson wrote: Anthony Pace wrote: I am not sure how to distinguish at what range or threshold a colour becomes too visibly similar to the eye to detect a difference, and I am really hoping there is a formula out there that I can be directed to. It depends on the context. If they are right next to each other and someone uses a magnifying glass, it is much more clear. But if they are two blobs that move and are on the opposite of a screen, it might be very hard.

[Flashcoders] visually similar spectrum
Does anyone have the math for at what range or threshold colours become too visibly similar to separate by the eye? Is there a good book or formula you know of? I am trying to implement some logic that makes it so if a colour value is repeated on the same pixel per frame, that it does not get redrawn, which is pretty simple; yet, I want to extend it to similar colours, and I am not sure how to distinguish at what range or threshold a colour becomes too visibly similar to the eye to detect a difference, and I am really hoping there is a formula out there that I can be directed to. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
