linking .swf or .fla to flash?

to make make all class instances play when the stage is clicked you would use:

package {     import flash.display.MovieClip;     import flash.events.MouseEvent;     public class Viz extends MovieClip     {         public function Viz()         {             stage.addEventListener(MouseEvent.CLICK, onClick); // if you want this object to play when it is clicked, use this instead of stage.         }         function onClick(event:MouseEvent):void         {             this.play();         }     } }           //////////////////////////////////// if you wanted all Viz instances to be invisible until the stage is clicked and then you wanted them to become visible and play, you could use:

package {     import flash.display.MovieClip;     import flash.events.MouseEvent;     public class Viz extends MovieClip     {         public function Viz()         {             this.visible=false;             stage.addEventListener(MouseEvent.CLICK, onClick);         }         function onClick(event:MouseEvent):void         {             this.visible=true; this.play();         }     } }
