Examples Flash Animation using swishmax 1 Bulles (script duplicateSprite)

Bubbles (duplicateSprite)

The purpose is to show bubbles rising up randomly.
It's only ActionScript. You couldn't test in SwishMax only in dans FlashPlayer and in a browser ( Export / SWF+HTML )
I suppose you know well how to create objects, thus I wont insist on.

Download background image.

Creating Objects

1 - Set up movie size 640x433 and background color #000072.
Frame Rate 50 fps or whatever.

2 - Insert image..

3 - Insert an empty sprite. Name it bulle0.(important) Target toggled

Scripts

In Outline, select scene, get in Expert Mode. Enter the following script :

onLoad () 
{ 
  whitesmoke= 0xF5F5F5;
  darkcyan= 0x008B8B;
  navy = 0x000080;
  cadetblue = 0x6F9EA0;
      // center  bulle0     
     xc = 320;    yc = 400;         R = 7.5;
    
     colors = [whitesmoke, cadetblue , navy, darkcyan ];
     alphas = [75, 75, 75, 75];
     ratios = [0, 150, 200, 50];
     matrix = {matrixType:"box", x:xc-2.2*R, y:yc-2.2*R, w:3.7*R, h:3.7*R, r:0  };
     bulle0.beginGradientFill("radial", colors, alphas, ratios, matrix);
      
     bulle0.lineStyle(1, cadetblue , 20 );
     bulle0.moveTo( xc+R, yc );
     drawCircle( xc , yc );
     bulle0.endFill();
    
     nbulles = 50;
        
}
// drawing bulle0
function drawCircle( x_c , y_c )
{
     n = 100;
     increment = 2*Math.PI / n;
    
     for ( j=1; j < n+1; j++)
     {    
       x = x_c + R * Math.cos( increment * j);
       y = y_c + R * Math.sin( increment * j);  
       bulle0.lineTo( x , y );
     }         
}
onFrame(1)
{     //  49 clones
   for ( i=1; i < nbulles; i++)
        duplicateSprite(_root.bulle0, "bulle"+i, i);  	       
}

In Outline, select sprite bulle0. Enter the following script :

onLoad()
{
     a0 = Math.randomrange(20, 100); // amplitude en x
     sc =  Math.randomrange(1, 8);   // scale variation
     T = 100;         // semi period
     h = -400;        // vertical amplitude
     this._X = 0;     // startup position 
     this._Y = randomrange( h, 0);
     this._xscale =  this._yscale = Math.randomrange( 10, 100);   // startup scale

}
onEnterFrame(includingFirstFrame)
{    // if limit in range
    if ( (this._alpha <= 10)  ||   (this._Y <= h ) )
      {
        a0 = Math.randomrange(20, 100);  
        
        this._Y = randomrange( h, 0);
        this._X = 0;
        this._alpha =  100;
        this._xscale =  this._yscale = Math.randomrange( 10, 100);
      }
    else 
      {       
        this._vY = -Math.randomrange(10,80);
        this._Y -= 2;
        this._X = a0*Math.sin( Math.PI * this._Y / T );
                // invert speed 1 out of 2
        this._vX = math.random(2);
        if ( Math.chance(50) )   this._vX = -this._vX;
               // decrease  alpha
        aa = Math.randomrange(0.1, 0.25);
        this._alpha -= aa;
               // decrease scale
        this._scaleX -= sc;
        this._scaleY -= sc;
      }  
}

Voilà, it's over.
Test and modify parameters carefully.

Note : Don't put any preloader 'cause behaviour 'll change.
