Using the Sine Wave formula from the previous post, I created this random fizz.

import flash.filters.BlurFilter;
 
// init vars
var SW = Stage.width;
var SH = Stage.height;
var clips = 35;
var minScale = 10;
var maxScale = 100;
 
/* ------------------------------------------------------------------------
INIT ANIMATION
---------------------------------------------------------------------- */
 
initAnim = function() {
 
// Move Clip
this.bubble._x = this.centerX + Math.sin(this.angle) * this.range;
this.angle += this.vx; this._y -= this.vy;
// Reset Position
if (this._y < 0) {
this._y = SH+this._height;
this._x = Math.floor(Math.random() * SW);
}
}
 
/* ------------------------------------------------------------------------
INIT STAGE
---------------------------------------------------------------------- */
 
initStage = function () {
 
for (i = 0; i <= clips; ++i) {
// Create Clips
var clip = this.createEmptyMovieClip("clip", i);
var bubble = clip.attachMovie("bubble", 'bubble', i);
// Set init size and position
clip._xscale = clip._yscale = minScale + Math.floor(Math.random() * maxScale);
clip._x = Math.floor(Math.random() * SW);
clip._y = SH + 100;
clip.bubble._x = -(clip.bubble._width/2);
// set movement vars
clip.angle = 0;
clip.range = 15 + Math.floor(Math.random() * 35);
clip.vx = .05 + Math.random() * .25;
clip.vy = 5 + Math.random() * 15;
clip.centerX = clip.bubble._x;
// Create Variable to determine depth for blur/Alpha amount
z = 10 + Math.random() * 50;
// Add Blur
var blur = new BlurFilter();
clip.tempFilter = clip.filters;
clip.tempFilter.push(blur);
// blur (max quality is 15)
clip.tempFilter[0].quality = z * .02;
clip.filters = clip.tempFilter;
// render movement
clip.onEnterFrame = initAnim;
}
}
 
initStage();
 
stop();
