Question

Ugh, so frustrated...

Hi, any help would be appreciated.  I'm trying to define a class that will make some textfields appear as if they're a blinking neonsign with a sound clip playing in tandem.  I got the code from a tutorial and it doesn't spit out any errors, but it doesn't do anything either. Please help, I'm desperate.

package ActionScript

{

import flash.net.URLRequest

import flash.display.*;

import flash.utils.*;

import flash.events.*;

import flash.filters.*;

import flash.media.*;

public class Flicker extends MovieClip

{

  private var timerOne:Timer;

  private var timerTwo:Timer;

  private var maxFlicker:Number = .85;

  private var neonClip:Sound = new Sound();

  private var soundControl:SoundChannel = new SoundChannel();

  private var NeonOff:MovieClip = new Title_Off();

  private var NeonOn:MovieClip = new Title_On();

  private var glow:GlowFilter = new GlowFilter(0xFF00FF, 1, 20, 20, 2, 3, false, false);

  private var blur:BlurFilter = new BlurFilter(5, 5, 2);

  private function timerInit():void

  {

   NeonOn.alpha = 0;

   timerOne = new Timer(2000,0);

   timerOne.addEventListener(TimerEvent.TIMER, timerOn);

   timerOne.start();

  }

 

  private function timerOn(e:TimerEvent):void

  {

   neonClip.load(new URLRequest("\Audio\neonClip.mp3"));

   neonClip.play();

   timerOne.stop()

   timerOne.removeEventListener(TimerEvent.TIMER, timerOn);

   addEventListener(Event.ENTER_FRAME, flickerOn);

  }

 

  private function flickerOn(e:Event):void

  {

   var ultraAlpha:Number = Math.random() * .9;

   NeonOn.alpha = ultraAlpha;

   if(ultraAlpha>maxFlicker)

   {

    NeonOn.alpha = 1;

    soundControl.stop();

    removeEventListener(Event.ENTER_FRAME, flickerOn);

    addEventListener(Event.ENTER_FRAME, allFlickerOn);

    addtimerTwo();

   }

  }

 

  private function addtimerTwo():void

  {

   timerTwo = new Timer(4000, 0);

   timerTwo.addEventListener(TimerEvent.TIMER, timerTwoEnd);

   timerTwo.start();

  }

 

  private function allFlickerOn(e:Event):void

  {

   var allAlpha:Number = .6 +(Math.random() * .4);

   NeonOn.alpha = allAlpha;

  }

 

  private function timerTwoEnd(e:TimerEvent):void

  {

   timerTwo.stop();

   removeEventListener(Event.ENTER_FRAME, allFlickerOn);

   timerTwo.removeEventListener(TimerEvent.TIMER, timerTwoEnd);

   timerInit();

  }

}

}

Was reading this thread and wondering how to implement the classin a way that the text would blink only passing the mouse over.......

kglad, remember how I thought you called me stupid? It was warranted; I never downloaded the sample files - now I understand how the original class works.  But thank's for your help and patience.

you're welcome.

and, i've done more stupid things while programming than possibly anyone on earth.  doing stupid things and being stupid aren't nearly the same and i wasn't even implying that you were doing something stupid. 

i couldn't see how that class was supposed to be used until i looked at the tutorial.  (and then it was pretty disappointing.)

p.s.  if this thread is closed, mark it as answered.  if you have questions, let me know.

Now I tried to move the class to the top level and I don't any error, but I don't get an effect either

before you ask, all my linkage is correct (don't mind "package ActionScript")

use the trace() function to debug.  start by adding a constructor to verify you're instantiating your class.

K, tried your advice, on the timeline actions I put the following code and now I'm getting a Error #2136, any ideas what I'm doing wrong?

import ActionScript.Flicker;

var TitleOn:MovieClip = new Flicker();
var TitleOff:MovieClip = new Flicker();

TitleOn.timerInit();
