View 3 RepliesI'm looking for a way to smoothly cycle through the color spectrum in an infinite loop, but I can't find any topics on the subject and don't really know where to start. I'd also like to be able to control how fast it cycles. I'm guessing I'd probably want to look into Tweener?

View 2 Repliesi've come across this ActionScript sample, which demonstrates drawing of the color spectrum, one line at a time via a loop, using waveforms.however, the waveform location of each RGB channel create a color spectrum that is missing colors (pure yellow, cyan and magenta) and therefore the spectrum is incomplete.how can i remedy this problem so that the drawn color spectrum will exhibit all colors?
// Loop through all of the pixels from '0' to the specified width.
for(var i:int = 0; i < nWidth; i++)

Trying to draw a triangle and then fill the color inside using the paint tool. I am not able to fill any color inside. Made sure the lines are overlapping, tried using the fill large gaps, made sure alpha is set to 100%.

I'm doing some line charts in my Flex application, and I need to draw segments of those line chart in different color. Does anyone have an idea how this could be achieved? For instance, if I have a code like this (actually, I have given this trivial example for simplicity (the problem is the same)):

I got some problems for drawing animation. Suppose I have a dot object. I want to have an animation which moves the dot to a position, and I want to do this for 100 times.

The running result is also wrong. how should I make this animation in the loop?
I have been pulling my hair out on this one for too long. I have a web banner that uses Erik Hallander's Pixelator Class. Everything works fine when the timeline plays just once, but as soon as it loops I get error:
ArgumentError: Error #2015: Invalid BitmapData.
I have tried removeChild, removeEventListener, nulling the variables involved, disposing of the BitmapData. I also tried some conditional statements depending on the loop but no success. The actual class code is beyond my experience.
We are creating an ecommerce site for my business and am trying to create a flash file that will allow the end user to select a color from a palette of 64 different swatches that they would like their item to be so it processed it into the order. I only need to create the flash file so they can select the color.

I am looking for RGB, for example, 0.5 0.5 0.5, for a gray color.Is there a chance the RGB parameters are hidden somewhere or is there a conversion function at least?
I'm trying to create a for loop to set the color objects outlineColor1...100 to the value defined in variable _root.outlineCol. Everything works fine when I set the color to these objects via 100 lines of code but I'd like to replace them with a for loop of course. I suspect the syntax in the first part of the second line is incorrect but I'm not sure.
for (var i:Number = 1; i <= 100; i++) {
outlineColor[i].setRGB(_root.outlineCol);
trace(i);
}
Having a for loop say like [code] need to generate color value for each i. need to set the color value for drawing rectangle dynamically
View 2 RepliesI have a movieClip over which I want to apply color effects such as making it flash white or in any other color.I can actually do this by duplicating that movieclip and use that duplicate as a mask...But, considering that movieClip is animated through code and is kinda complex, it somehow doesn't feel very optimized.I was wondering if there was a way to tell actionscript to "draw the color only over the pixels that constitute the rendered shape", rather than creating a complete duplicate.
View 3 RepliesI'm trying to figure out the AS3 equivalent of this AS2 code. In this example there would be 10 movie clips on the stage with instances of "mp0", "mp1" etc... The actual project has hundreds of movie clips.
PHP Code:
for (i=0;i<10;i++){
var sectorColor:Color = new Color(_root["mp"+i]);
[code]....
I have this code to change the colors of some movie clips[code]...
Since I have lots of buttons, I wanted to consolidate this code into a For loop.
I`m working on a app that you can draw lines.....like circles, rectangles... my problem is when a user draw a circle for example....i wanna be able to paint (change color) inside of this circle. I`ve tried working on Shapes with cacheAsBitmap = true and Bitmaps with BitmapData but it doesn`t seens to work.
View 4 Replieswhat's the best route to putting together a spectrum slider? Component? (for purchase even, must be re-skinable) Tutorial FLA? Tween Extension Mod? I'm wondering what the best process of approach is. Algorithmic or sampling.
View 2 Replieswhen it comes with actionscript. So far, I dragged a MoveClip which i called "ledLight" to the stage multiple of times which resemble (you guessed it) an LED light displaying the words "EMOTION". in giving a Movie Clip that displays a slow flow of spectrum colors. The problem I have is I have no clue how to do that!

I'm using the F8 bitmap object and this image for a color preferences panel, and would like to use the same image for a fall-back to F7.
For F8, I'm using getPixel(), for F7 I'll need to determine the color (or as close an approximation as possible) using the math used to create this type spectrum.
Came across this great code for a simple mp3 player with audio spectrum on another site.Works and looks great.Thing is, I have multiple players .swf on a single .html page. When one mp3 is playing all the other player's audio spectrums are triggered as well. Having a hard time figuring out how to trigger only the spectrum for the mp3 being played.

I am trying to make a sound spectrum that uses a circle.I have finished the easy part and am trying to add a blur filter to it.I followed a tutorial, except only the bottom right quarter of the circle will blur.I've tried messing with it but I've gotten no luck.Here's the code.
Code:

I can't figure out why I am not able to make this work here is an example of what I am doing.I am importing an AS file that plays a spectrum and the song I have. Here is the code.

I have made a MP3 Player in which spectrum bars acts on Sound.. I used computeSpectrum function from SoundMixer Class. Everything is going well.... But when I run my player and open any other player (from You tube for example) in the same window then Spectrum bars stops responding. I want my players Spectrum bars should not be interrupted even if other player is opened in same browser window,.... is it possible ??
View 3 RepliesI know the SoundMixer.computeSpectrum and Sound.extract() methods , but those methods deal with the total sound output. Instead, is there a way to deal with every single SoundChannel, so as to provide a graphical visualization of each of them?
View 1 Replieshow to make an spectrum analyzer in flash and explain it piece to piece cause i found an explanation but it was kind of super hard to understand, so please help.
View 1 RepliesJust wanted to ask, is it at all possible to create sound spectrum from the data that RTMP server streamed? I read this computeSpectrum and it says
"In addition, this method cannot be used to extract data from RTMP streams, even when it is called by content that reside in the same domain as the RTMP server."
I will not be using FMS so it stays inpossible. Are there any available hacks with php and the server or whatever?
I am action script developer in a company. I want to render my freequency spectrum while loading sound.I tried it different way.please suggest any way to do it
View 0 RepliesI am trying to create a sound spectrum analyiser, or as I call it, audio visualization. I have seen many examples, including the competition held on this site. However, I have yet to find anything on real time audio, whereby the spectrum reacts to sounds it hears rather than pre compiled songs. provide me with links to some tutorials on real time sound spectrums
