No exit on the left and right (x) borders

programming flash
1

Hi!

I am using this script to make something else than snow to go upwards instead of down.
However. I would like to have the “snow” not to exit on the right and left side of the borders of my flash file. Because there is a “blink” effect when there is a exit on the sides. This means that I want the “snow” to exit only on the upper border of the flash movie. My movie is 790 x 145 px.

Please help me out on how to modify this script for this. I have attached a zip file of my FLA.

Best regards
Joakim


init = function () {
    width = 790;
    // pixels 
    height = 145;
    // pixels 
    max_snowsize = 20;
    // pixels 
    snowflakes = 8;
    // quantity 
    for (i=0; i<snowflakes; i++) {
        t = attachMovie("snow", "snow"+i, i);
        t._alpha = 100+Math.random()*20;
        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 = +125;
    }
    if (this._x>width+25) {
        this._x = -(width/2)+Math.random()*(1.5*width);
        this._y = +125;
    } else if (this._x<+5) {
        this._x = -(width/2)+Math.random()*(1.5*width);
        this._y = +125;
    }
}
init();
