Hello guys, i am trying to make a so called pixel effect in witch I want to make a shape only from pixels that are positioned in some random place on the stage. And all these pixels move to a certain point and create that shape.

I now this is a long shot for a newbe like me but i’m willing to learn.

So could somebody give me some clue on how to begin this. I’ve been looking into BitmapData Class but i don’t now if that is the best way to do it.

:ear:

There is more than one way to do this of course. Here’s one way. It’s inspired by (although not identical to) Hack #2 in Sham Bhangal’s _Flash Hacks_, which you might want to check out if you can get a hold of it.

[AS]function move() {  
this.\_x += (-this.\_x+this.x)/this.speed;  
this.\_y += (-this.\_y+this.y)/this.speed;  
if (Math.abs(this.\_x - this.x)\<.5 && Math.abs(this.\_y - this.y)\<.5) {  
delete (this.onEnterFrame);  
}  
}  
pixelnum=0;  
for (i=shape.\_x; i\<shape.\_x+shape.\_width; i++) {  
for (j=shape.\_y; j\<shape.\_y+shape.\_height; j++) {  
if (shape.hitTest(i, j, true)) {  
clip = \_root.attachMovie(“pixel”, “pixel”+pixelnum, pixelnum);  
clip.x = i;  
clip.y = j;  
clip.speed = (Math.random()\*2)+2;  
clip.\_x = Math.random()\*Stage.width;  
clip.\_y = Math.random()\*Stage.height;  
pixelnum++  
}  
}  
}  
launcher = 0;  
queue = setInterval(launch, 5);  
function launch(){  
\_root[“pixel”+launcher].onEnterFrame = move;  
launcher++;  
if (launcher == pixelnum){  
clearInterval(queue);  
}  
}[/AS]
