View 2 RepliesLately 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.
View 2 RepliesI 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.
View 12 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?

What I need is to make them run in a sequence, someone have a clue?
When I test the site with the preloader.swf file I made for it, it loads, but then some of my button functions do not work in the site. When I test the site fla file everything works fine. I have been trying things out with the preloader code, but not sure what would cause this.
This is my preloader code:
var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent .PROGRESS, loop);
l.contentLoaderInfo.addEventListener(Event.COMPLET E, done);
l.load(new URLRequest("sample.swf"));
prog_mc.stop();
function loop(eventrogressEvent):void {

How would I go about making my own functions for objects and movie clips?
Like:
Code:
onClipEvent(enterFrame){
this.setpos(10, 20);
}

View 3 RepliesI have a .3ds file for the model and a .dds file for the texture. I am able to load .3ds model by using the code:
Code:
var model:Max3DS = new Max3DS("model");
model.load("assets/model.3ds");
How should I load the texture from .dds file and apply it to .3ds model?
I must say I'm a little puzzled by the mipmap functionality in the newer flash players.URL...Tinic describes the way that mipmaps work in flash player if the images are specific sizes (e.g. powers of 2 like 256x256 etc). The demo here URL... shows this working quite clearly and I have myself demonstrated that when using a simple bitmap object with smoothing set to true then scaling has a much better result when the images are the correct dimensions for mipmap capabilities.However I have not seen mipmaps work in 3D when using bitmapFill and drawTriangles. The bitmap quality seems to look crappy regardless of the bitmap size. Do mipmaps ever work in 3D with bitmap fill etc? This topic direct from Adobe seems to imply that it does URL...with the comment "Use bitmap sizes that are divisible by 4 or 8 for two-dimensional images (such as 640 x 128, which can be reduced as follows: 320 x 64 > 160 x 32 > 80 x 16 > 40 x 8 > 20 x 4 > 10 x 2 > 5 x 1) and 2^n for three-dimensional textures".However a few other sources such as this one implies that it doesnthttp:URL...with the comment "Mipmapping was introduced in Flash Player 9 but it doesn't work with 3D drawing and requires textures to be even in resolution. That is why we developed our own method of filtering."
View 1 RepliesI am using Papervision3D Flash 3D engine to render a model. Also I am noob in 3D =D Model is simple, it's a parallelepiped with different textures on its sides. All works just fine except one thing: whenever I change my visual angle to a model from 90° textures on the sides are distorted. I notices that it is common effect in 3D graphics, I saw that effect in games and other 3D renderers (i.e. away3D, three.js) even wth different 3D models. Distorted texture on object (different view angle): Normal texture on object (same object and texture) (view angle == 90°): What is the reason of this effect?
View 1 Repliesis anybody here who have and would be willing to send me png2atf tool for compressing textures? It was part of the prerelease of Adobe about a year ago.
View 0 RepliesI'm trying to create multiple objects in Papervision using Flash Builder, each one with it's own texture that I'm getting from an imported SWC.My code works perfectly if I apply one texture to all shapes, but when I try to put it into a loop I can't seem to get it to work. I think this is more of a syntax problem, I'm just not sure how to tell Flex what I want.Here's a chunk of the code that works fine, applying an "img1" texture to everything: [code]Does that make sense? I want each iteration of the loop to add a number to the end of "img" and apply that to the shape.
View 8 RepliesSo basically I want to make a quiz where the user identifies textures in images. The first image is of a shell. So I want the user to be able to type in their answer into a input text field, then press a "check answer" button. Then if they typed in shell "Correct" will appear in a dynamic text field or "incorrect" if they had typed in any other answer.
with the action script required for this button, I am using action script 2 in flash cs4.
I found this code on the internet but it didn't work.
on (release) {
if (input_instance_name=="correct answer"){
display_instance_name.text="Correct!";
}

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.
my 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
