Question

Does ActionScript 3.0 offer any means to accept an arbitrary number of parameters? I usually use .NET, but I’m being forced to use AS3 for a project and something along the lines of function blah(params double[] x) would be awesome for a helper library.

Thanks;

Check out the rest parameter: http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/statements.html#…_(rest)_parameter

package {   import flash.display.MovieClip;    public class RestParamExample extends MovieClip {     public function RestParamExample() {         traceParams(100, 130, 'two'); // 100,130,two         trace(average(4, 7, 13));     // 8     }   } }   function traceParams(... rest) {  trace(rest); }  function average(... args) : Number{   var sum:Number = 0;   for (var i:uint = 0; i < args.length; i++) {     sum += args[i];   }   return (sum / args.length); }
