Falling Snow

1

Hi!!! I need create bubbles in flash, I used the fallinng snow script but I need that the particles go to the sky and not go to the floor :’( please heeeeelp. This is the code…

onClipEvent (load) {
//specifies the size of the movie stage
movieWidth = 78;
movieHeight = 516;

    //variables that will modify the falling snow
i = 1+Math.random()*1;
k = -Math.PI+Math.random()*Math.PI;

//giving each snowflake unique characteristics
this._xscale = this._yscale=30+Math.random()*60;
this._alpha = 50+Math.random()*100;
this._x = 10+Math.random()*movieWidth;
this._y = 10+Math.random()*movieHeight;

}
onClipEvent (enterFrame) {
//putting it all together
rad += (k/180)*Math.PI;
this._x -= Math.cos(rad);
this._y += i;
if (this._y>=movieHeight) {
this._y = 5;
}
if ((this._x>=movieWidth) || (this._x<=0)) {
this._x = 20+Math.random()*movieWidth;
this._y = 5;
}
}

Thnks !!! :snug:
