Please help turn AS2 Smoke into AS3 smoke??

hi,

I found a great smoke tutorial here: www.pixelhivedesign.com

I have been trying to turn this actionscript 2 into actionscript 3... is that possible?

// ------------------------------------------------
// Realistic Smoke Effect - www.pixelhivedesign.com
// ------------------------------------------------
fadeSpeed = 1; // Smoke fade speed.
floatUpSpeed = 2; // Smoke float up speed.
// Every frame attach a puff of smoke.
this.onEnterFrame = function(){
// Get next available depth.
d = this.getNextHighestDepth();
// Attach a puff of smoke.
aPuff = attachMovie('aPuff','aPuff'+d,d);
// Set initial scale to 10%.
aPuff._xscale = aPuff._yscale = 10;
// Put puff where the mouse is. (add small random)
aPuff._x = Math.random() * 5;
// Randomizes the starting animation for realism.
aPuff.gotoAndPlay(Math.round(Math.random()*20));
// Smoke will animate each frame.
aPuff.onEnterFrame = function(){
// Scale smoke up.
this._xscale = this._yscale += fadeSpeed;
// Fade smoke.
this._alpha -= fadeSpeed;
// Smoke floating up.
this._y -= floatUpSpeed;
// When smoke is 100% scale, remove it.
if(this._xscale >= 100){
this.removeMovieClip();
}
}
}

Can anybody help me? at the moment im getting lots of access of undefined movie problems and it also doesnt like Attachmovie...

Any help would be brilliant, Thanks very much!

As a start:

1. You need to eliminate all the underscores from _y etc.
2. for attachMovie you need to create a new object.
3. onEnterFrame function should be replaced by a listener.

PHP Code:

---

const fadeSpeed:int = 1; // Smoke fade speed.
const floatUpSpeed:int = 2; // Smoke float up speed.

//  every time the stage ticks a new frame, run this:
addEventListener(Event.ENTER_FRAME, function(e:Event):void{
    
    //  create a new aPuff object from the library
    var puff:aPuff = new aPuff();

    //  set it up
    puff.scaleX = puff.scaleY = .1;
    puff.x = Math.random() * 5;
    puff.gotoAndPlay(int(Math.random() * 20) + 1);

    //  hook puff up to enterFrame function: puffFrame
    puff.addEventListener(Event.ENTER_FRAME, puffFrame);
});


//  this is run every frame for every puff
function puffFrame(e:Event):void{
    e.target.scaleX = e.target.scaleY += fadeSpeed;
    e.target.alpha -= fadeSpeed;
    e.target.y -= floatUpSpeed;

    //  check for 100% scale
    if(e.target.scaleX >= 1){
        //  remove from stage
        removeChild(e.target);

        //  stop updating and allow puff to be garbage collected
        e.target.removeEventListener(e.type, arguments.callee);
    }
}

Anyone get this to work?

:)

p.s.: first piece of code goes into a class file. second piece in main timeline. third piece if yu want to randomly change the smoke's color. worked for me...
