SWF It Good

I miss writing classes w/ 50 or so lines of code and here is one. This is a take off of Lee Brimelow’s Example of Dynamic Sound Generation. I’m using the BitmapData to create a tone.

[as]

package
{
import flash.display.*;
import flash.events.*;
import flash.media.*;
import flash.net.URLRequest;
import flash.system.Capabilities;
import flash.text.TextField;

public class DynamicSound extends Sprite
{
private var sound:Sound;
private var noise:Number = 0;
private var _loader:Loader;
private var _bm:Bitmap;
private var _verText:TextField;
public function DynamicSound():void
{
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
_verText = new TextField();
_verText.text = Capabilities.playerType + ” (” + Capabilities.version + “)”;
_loader = new Loader();
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete, false, 0, true);
_loader.load(new URLRequest(“http://www.scarlet.nl/~ivo/photo_ASTRO3.JPEG”));

}

private function onComplete(evt:Event):void
{
_bm = Bitmap(_loader.content);
addChild(_bm);
addChild(_verText);
sound = new Sound();
sound.addEventListener(Event.SAMPLES_CALLBACK, onCallback);
sound.play();
}
private function onCallback(e:SamplesCallbackEvent):void
{
for(var i:uint=0; i<512; i++)
{
noise += _bm.bitmapData.getPixel(mouseX, mouseY)/ 44100;
var sample:Number = noise * Math.PI * 2;
sound.samplesCallbackData.writeFloat(Math.sin(sample));

sound.samplesCallbackData.writeFloat(Math.sin(sample));
}
}
}
}

Quick and Dirty!

Alright, this example is very similar to the other examples I have done. But with this one I am scaling all pixels at the same rate. Just click on it the image in the example Read more »

Alright, in this example, I am cutting each pixel in an image and piecing it back together again. Only this time I animating the pixel to a new location, piecing back the image at 200%. I think this can open a lot doors in what you can do with a bitmap. Read more »

So the last couple of weeks I have been jacking around w/ Bitmaps and BitmapData. I’ve always wanted to try it but never had the courage. Now that I have, I wish I’d have done it sooner.

In this first example I’m just copying each pixel throwing it to the wind and using Tweener to animate it to a spot. I don’t think Tweener is the best option course as you can see it runs slow. I’m also using Grant Skinner’s Memory Gauge to illustrate how slow it is. This is just a proof of concept anyway.
