actionscript - loop through instances of movieclips flash -

i have bunch of movie clips on layer named s1, s2, s3, .. s16.

i need add them array can select random number play.

something like:

var sparkle:array   =   new array(); var i:int = new int; for(i=0;i=16;i++) {     sparkle[i] = 's'+i; } 

if know total number of movieclips, don't need store them in array.

get random number first

var random:int = math.round( math.random() * totalnumber ); 

then can use function return mc want

private function getmovieclip(value:int ):movieclip {     var mc:movieclip;      for( var i:int ; < totalnumber ; ++i )     {          if( this.getchildat(i).name == "s"+ random.tostring() )          {              mc = this.getchildat( ) movieclip;              break;          }     }      return mc; }
