Snow 3.0 tutorial tweak help

Hello

I’m trying to tweak the snow 3.0 tutorial so that the flakes don’t all appear at once. I searched around couldn’t find the answer for flash8.

Here’s the code

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();

What I want to do is have the flakes come in one at a time, like one every couple milliseconds. Right now they all appear at the same time and fall, I want it staggered.

Anyone know what the best way to do that would be?

Thanks in advance
