I have this tutorial code from AS3 Cookbook, fog like effect on Bitmap data
Code:
import flash.display.Sprite;
import flash.display.Bitmap;

how to get the Perlin Flag Wave shown at
Senocular[dot]com/flash/source/?entry=761
to go from right to left?
Reversing the gradient of the displacement does not work. It simply reverses the amount of the effect on the left side so the waves are bigger on the left end, but the waves still move from left to right.
how can i create the 3D perlin noise effect in flash?
View 1 RepliesI have been trying to create a visual noise pattern using bitmapData.noise, and with help from Rothrock and Kglad have created a working version.I checked with a colleague who is expert on the use of these visual patterns, and he suggested that the change speed is too fast: that the dots (pixels) need to change at just under 400 dots per second for an 800 x 600 stage.With beginner skills in AS3, I am unsure if there is any way to change the script to slow the rate of dot change in the bitmapData.noise function?

View 7 RepliesI'm trying to figure out the best way to compare a single bitmap against perhaps an array of saved bitmaps to see how close of a match it may be to any one of the bitmaps stored in the array. Right now I'm running a for loop that uses the bitmapData.compare() method to try to compare to see how much of a variance there is but... to be honest I'm at a loss as to how to use the resulting data to do so. Does anyone know of any good method to accomplish what I am trying to do? Forget looking at my code it's a waste of time because simply, it's not working.

View 1 RepliesI have been searching for a few days now, I keep seeing the question, but no answer. I created a text effect using a mask. It works great when I move through the timeline.However, when I test the movie or publish it as swf or htmp, the mask doesn't work. As I was searching for an answer, I noticed several references to making sure the font is embedded, so I made sure I did, but it's still not workingI am using:Flash Professional CS5Windows 7Flash Player 10ActionScript 3.0

View 3 RepliesWhat is an alpha threshold?
View 11 RepliesI'm building a flash app that pulls images from flickr and removes the white background. I'm doing this using threshold and I get a really ragged outcome. Is there any way to get a better and smoother color key?
photoNumber = Math.floor(Math.random() * (photos.length));
loader.load(new URLRequest(photos[photoNumber].path));
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,draw);
trace ( "trying to load photo " + photoNumber );

View 0 Repliesis there a type of variable that understands that 360 is less than 0
[Code]...
this works as long as i dont cross the 360/0 threshold (it may be -180/180 since i removed the +180)
I am stuck with a requirement to display a horizontal line on a ColumnChart to indicate a threshold level. I have the data to the Chart as an ArrayCollection.
Is it possible to get the location of a value that is shown on the y axis? I think I will be able to place a line or 1px high canvas on top of the Chart to achieve this. Or better, is there any built in functionality that i may have overlooked or is there some open library that can achieve something like this?

I have not had much luck so far, I've only managed to generate a black and white image, or nothing at all.

In the below code sometimes when microphone is not connected some noise is generated and the system just keeps on buzzing the same sound.Whats wrong with the code below and how to reduce the unwanted noise. Should i set myMic.setLoopBack(false) in the below code

Lately I have been trying to animate the water surface giving it more natural look by use of Perlin noise. But it seems it is very CPU intensive operation. And if I use it along with other animations on the stage which involve lot of movements then it become really difficult for the machine to render the entire scene.

I am wondering if there is any way to set the pixel colors exclusively to black and white (instead of gray) in a bitmapData.noise animation. The previous related thread is: [URL]..For the function:
function makeNoise():void { _bitmapData.noise(getTimer(), 100, 255, 7, true);
Is there any way to set the noise color pattern to black and white? In the scripting reference, it seems the choices are R||G||B||Alpha channels, so I am not sure if there is any way to combine these to get black and white only.

View 2 Repliesmy issue is with flash FLVplakback control with a seekBar attached to it. example can be found here. for some unknown reason when i try to rewind using the seekbar, it produces a loud noise at the start. whereas if i let it play out the entire movie (mp4) and then play again using the play button it does not produce such noise. in case i rewind using the seebBar after playback has completed even then it does not produce the noise.
View 1 RepliesI'm trying to implement the face recognition api from [URL] Everything is working fine other than the fact that the x y position of the face returns a lot of noise, meaning that when I'm sitting still instead of the x y to be constant it jumps up and down. Is there a way to apply a filter to the returned x y values to prevent this from happening?
View 4 RepliesWhat is the easiest way to add a chime noise on the hour or every 15 minutes to my AS3 clock? I have the code all written for my date/time calendar and I thought it would be neat to add a sound. This is my AS3 code:
import flash.events.Event;
import fl.events.ColorPickerEvent;
import flash.geom.ColorTransform;
theTime.addEventListener(Event.ENTER_FRAME,showTime);
seconds.addEventListener (Event.ENTER_FRAME,showSeconds);

im having a bit of trouble with something,if you look at the attached file, there are 2 circles(movie clips), they have an AS code on them :
onClipEvent (enterFrame) {
if (this.hitTest(_root._xmouse,_root._ymouse,true)) {
this._x = int(Math.random()*550);
this._y = int(Math.random()*400);
}
}
Now, i wanted to put a sound on the rollover, so when it ran away, it would make a noise, so i put an invisible button on the top in each movie-clip.and put a sound on the over state, but, this makes the MC's not run away!So i thought that i could add a on (rollOver), but i dont know the code to load a sound from the library.
I am trying to get a loop repeating as background noise I have implemented this within an MC on maintime line.
Code:
myLoop = new Sound;
myLoop.setVolume(80);
myLoop.attachSound("final");
myLoop.start(0 ,99);
var pos:Number;/////user interface below
By me starting loop at 0, playing back 99 shouldnt that loop it endlessly? However it stops after first play.
Is there a way to pre-render a BitmapData.perlinNoise moving animation into a seamless loop of 10-12 frames from which copypixels could be used on the resultant sprite strip to produce fast resuilts?
