Hi,

I am trying to convert an as2 script to as3. Having never dabbled in as2 i am having trouble with the attachMovie and how to convert this to as3. I know it should be addChild but it is the extra parameters that are confusing me.

Can anyone help? The as2 code is below.

Thanks
for (i=0; i<snowflakes; i++) {
		
t = attachMovie("snow", "snow"+i, i);
 
}

If the name of the movieclip is "snow" then:

for (i=0; i<snowflakes; i++)
{
 
this.addChild(new snow())              
 
}

The extra parameters in AS2 are indicating that the name of the movieclip is "snow" (1st arg), the instance name should be "snow0", "snow1", etc. (2nd arg), and the level should be one higher than the last one (3rd arg).

In AS3 you don't have to worry about levels anymore.  As far as using instance names goes for this type of operation, I've often found it easier to put "snow" into an array, and then just manipulate the index of the array if need be, not worrying about assigning a unique instance name to each new movieclip instance e.g.:
var snowArray:Array = new Array();
 
for (i=0; i<snowflakes; i++) 
{
   snowArray.push( new snow() );
   this.addChild( snowArray[i] );            
 
}

this is the original script, it is the looping and adding of movieclips that I cannot get.


Thanks,

H
init = function () {
	width = 300;
	// pixels 
	height = 200;
	// pixels 
	max_snowsize = 10;
	// pixels 
	snowflakes = 50;
	// quantity 
	for (i=0; i<snowflakes; i++) {
		t = attachMovie("snow", "snow"+i, i);
		t._alpha = 20+Math.random()*60;
		t._x = -(width/2)+Math.random()*(1.5*width);
		t._y = -(height/2)+Math.random()*(1.5*height);
		t._xscale = t._yscale=50+Math.random()*(max_snowsize*10);
		t.k = 1+Math.random()*2;
		t.wind = -1.5+Math.random()*(1.4*3);
		t.onEnterFrame = mover;
	}
};
mover = function() {
	this._y += this.k;
	this._x += this.wind;
	if (this._y>height+10) {
		this._y = -20;
	}
	if (this._x>width+20) {
		this._x = -(width/2)+Math.random()*(1.5*width);
		this._y = -20;
	} else if (this._x<-20) {
		this._x = -(width/2)+Math.random()*(1.5*width);
		this._y = -20;
	}
}
init();

It's something like this:



for (i=0; i<snowflakes; i++) 
{
   snowArray.push( new snow() );
   this.addChild( snowArray[i] );   
   snowArray[i].alpha = 20+Math.random()*60;
   ...
   snowArray[i].addEventListener(Event.ENTER_FRAME, mover);
 
}
 
private function mover (event:Event):void
{
    this.y += this.k;
   ...
}

The ENTER_FRAME event may not work right in this case though.  I can't remember the different scopes of 'this' in AS2.
