I 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?

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?

View 1 RepliesMoved from Newbie section I have beginner skills using AS3 and have been trying to improve a basic movie that generates a visual noise pattern. I need it for an eLearning lesson. A while back, I got some help pulling this script together. It uses bitmapData.noise to generate a visual noise pattern. It can be viewed here: [URL]
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. I tried changing the "seed" parameter, but while this slowed down the pixel-dot change, it did not run smoothly. I'm not sure what else can be scripted to accomplish slowing down the change rate

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.
affect the position of a sprite using perlin noise? Looking at this flag example:
[URL]
If you imagined a sprite with say just a circle drawn in it positioned on the top right corner of the flag, is there a way to calculate the change in position to keep it in-sync with the flag corner as that animates? What I'm after is the fluid motion but not the distortion.
I want that my spaceship gets louder when my mouse moves away from it (and vice versa). Problem is that my function produces an annoying crackling sound I can't get rid of when I move my mouse away from it (and vice versa). The sound file is ok so far.
Code:
shipSpeed = (abs(player.x - playerPrevPt.x) + abs(player.y - playerPrevPt.y)) / 2;//the ship's speed gets calculated
//this is used to determine whether the ship's volume of its sound shall be increased or decreased

I have a strange issue with the FLV files i imported to my site.These FLVs were imported with Alpha channels.In my site there is a button, that when its pressed for each FLV it starts playing.The Problem is after its been playing for awhile there is a strange Noise at the background that starts appearing slowly. (Please see attached file)The only code i have on each FLV is for transparety and a Loop (Plaese see below):
onClipEvent (load) {
this._alpha = 0;
this.dir = -1;

I'm running CS5.5 on an intel Mac 10.6.5, and I have been having problems encoding to flv. All my videos are edited the same way, and using the same formats etc., yet recently I have found that when converting to .flv, some will work fine, and others will have the audio replaced by white noise.
Checking through the video specs, it appears that the one difference is that the ones which worked fine are all Apple ProRes 422 HQ files, and the ones which failed are Apple 10bit Uncompressed. The strange thing is the audio is the same for both. Yet when the encode problem happens, the video for both is fine, its just the audio where the problem appears.
I am using these settings for media server but there's too much noise when a mic is attached to stream. Code is as following, can you suggest changes to remove the noise for more crystal clear voice?

I was thinking the other week - wouldn't it be great to have a flash clock that not only tells a classy analogue time but also, like a church clock, gives out bell noises when the hour is reached, an also chimes the number of hours the time corresponds too. So at 1pm/am it will chime once, and at midnight you get 12 chimes and so on, I'm sure you get my meaning. I'm not great when it comes to working with sound, infact I've never added much more than a custom click noise on a button. How to go about this? I've attached a nice church bell noise for y'all just incase.
