How can I alter Kirupa’s snow effect ( [http://www.kirupa.com/developer/mx/snow.htm](http://www.kirupa.com/developer/mx/snow.htm) ) so that it begins on a slow start? Just have little snow start it off and then gradually reach the original effect.

</div>

instead of this code:

```auto
for (k=0; k<50; k++) {
	duplicateMovieClip(_root.snow, "snow"+k, k);
}

```

use this one:

```auto
var index, maxSnow = 50;
this.onEnterFrame = function() {
	if (++index<=maxSnow) snow.duplicateMovieClip("snow"+index, index);
	else delete this.onEnterFrame;
};

```

like that? 🙂

1. How do I get it to come in even more gradually? Ideally, I want to start out with 1 snowflake.
2. How do I make the snow fall only in one specific area of my movie? IE X=300, Y=200, Height=100, Width=400.

1. the code i posted duplicates de snow at the fps of your movie, if you want it slower/faster you could set up a function to duplicate the snow and an interval to call the function.

```auto
var index, maxSnow = 50;
duplicateSnow = function() {
if (++index<=maxSnow) snow.duplicateMovieClip("snow"+index, index);
else clearInterval(snowInterval);
};
var snowInterval = setInterval(duplicateSnow, 1000/4);

```

that way it would be duplicated 4 times per second.

1. i already answered that question. i couldn’t find the stupid thread so here it is again. 😛

```auto
onClipEvent (load) {
	var xmin = 40, xmax = 140, ymin = 40, ymax = 240;
	i = 1+Math.random()*2;
	k = -Math.PI+Math.random()*Math.PI;
	this._xscale = this._yscale=50+Math.random()*100;
	this._alpha = 75+Math.random()*100;
	this._x = xmin+Math.random()*(xmax-xmin);
	this._y = ymin;
}
onClipEvent (enterFrame) {
	rad += (k/180)*Math.PI;
	this._x -= Math.cos(rad);
	this._y += i;
	if (this._y>=ymax || this._x<=xmin || this._x>=xmax) {
		this._x = xmin+Math.random()*(xmax-xmin);
		this._y = ymin;
	}
}

```

change the xmin, xmax, ymin and ymax values to whatever you need. 😉

All your code worked. Thanks.

How do you get the snow to appear on the actual layer that I put it on? It appears as the top layer and blocks a bunch of stuff on my site.
