actionscript 3 - How do I control a movieclip using a button? -

actionscript newbie. actionscript 3.0 started following tutorial @ http://republicofcode.com/tutorials/flash/basicwebsite/ works fine long code remains in flash file. when move external file have issue.

i have following code on action layer keyframe:

    stop();  function gohome (e:mouseevent):void{ gotoandstop("home"); } home_btn.addeventlistener(mouseevent.click, gohome);  function goabout (e:mouseevent):void{ gotoandstop("about"); } about_btn.addeventlistener(mouseevent.click, goabout);  function golinks (e:mouseevent):void{ gotoandstop("links"); } links_btn.addeventlistener(mouseevent.click, golinks);  function gocontact (e:mouseevent):void{ gotoandstop("contact"); } contact_btn.addeventlistener(mouseevent.click, gocontact); 

everything works fine want move code external as3 file , running issues.

i have added document class "site1" , name of external file. removed code flash file keyframe , moved external file.

here code appears in site1.as

    package { import flash.display.movieclip; import flash.events.mouseevent; import flash.text.textfield;  public class button extends movieclip{      public function button() {         function gohome (e:mouseevent):void{ gotoandstop("home"); } home_btn.addeventlistener(mouseevent.click, gohome);  function goabout (e:mouseevent):void{ gotoandstop("about"); } about_btn.addeventlistener(mouseevent.click, goabout);  function golinks (e:mouseevent):void{ gotoandstop("links"); } links_btn.addeventlistener(mouseevent.click, golinks);  function gocontact (e:mouseevent):void{ gotoandstop("contact"); } contact_btn.addeventlistener(mouseevent.click, gocontact);     } } } 

the problem when publish flash file keeps looping , not pausing button click.

any @ appreciated.

name class , file same name. suggest following code.

package {     import flash.display.movieclip;     import flash.events.mouseevent;     import flash.text.textfield;      public class yourclassname extends movieclip     {         public function yourclassname() {             home_btn.addeventlistener(mouseevent.click, gohome);             about_btn.addeventlistener(mouseevent.click, goabout);             links_btn.addeventlistener(mouseevent.click, golinks);             contact_btn.addeventlistener(mouseevent.click, gocontact);                   }          private function gohome(e:mouseevent):void {             gotoandstop("home");         }                 private function goabout(e:mouseevent):void {             gotoandstop("about");         }          private function golinks(e:mouseevent):void {             gotoandstop("links");         }          private function gocontact(e:mouseevent):void {             gotoandstop("contact");         }      } } 

as3 more explicit as2. suggest use private / public accessors.

edit.

'button' not class name, work.

1) name file, class , constructor : 'button' :

public class button extends movieclip  public function button() 

2) sure linkage good! meaning : if want control whole movie class, change document "class" name button , if want control movieclip library, drag on stage, check "export action script", , change "class" value button.

think method, don't need instance name. class linkage enough in case.
