Flash As3 Mute Button problems

Question

Hey guys,

I am trying to create a UI movie clip that can be used across different scenes. It uses variables from the root scope to determine states.

When i press the mute button is works fine, however when i try to un-mute things go weird. Sometimes it takes 2 clicks to unmute, sometimes more. It seems random. Muting however seems to work first time..

Any ideas?

Main Timeline:

var mute:Boolean = false; var playerName = "Fred";

function setMute(vol) { var sTransform:SoundTransform = new SoundTransform(1,0); sTransform.volume = vol; SoundMixer.soundTransform = sTransform; }

function toggleMuteBtn(event:Event) { if (mute) { // Sound On, Mute Off mute = false; setMute(1); ui_mc.muteCross_mc.visible = false; } else { // Sound Off, Mute On mute = true; setMute(0); ui_mc.muteCross_mc.visible = true; } }

ui_mc Action Script:

if (MovieClip(parent).mute == false) { muteCross_mc.visible = false; }

mute_btn.addEventListener(MouseEvent.CLICK, MovieClip(parent).toggleMuteBtn);

I'm assuming that your code is on the first frame of your timeline.

I won't go into depth with the issues regarding that practice in as3, but you might be better off using a document class. That way the code is initialized only once. I'm guessing when you're switching between the scenes, you keep re-initializing, so you end up resetting mute to false.

To check if this is happening, just add a trace("init") to that script, and see how often you call that., you can also add a trace to your toggleMuteBtn function to see what the mute variable is before you change it.

on a side note, I'm curious why you're typecasting the parentMovieClip(parent) though it won't cause any problems, there is no need for it as you could just use parent
