Disabling Audio Flash - actionscript-3

When creating an AS3 project and adding audio what I usually do is drag the audio I want to use (for a game menu for example) and when I want to stop the audio I enter
SoundMixer.stopAll();
I do this because if I say go to the about game frame in this menu then I will have the audio, but if I come back to the main frame where I originally had the music it sorta doubles in and the two different timings of the music are playing at the same time.How do I stop this without having to disable the audio when I change frame?

In these cases, it is easier to start and stop the sound directly via code. First, right click the sound clip in your Library panel, and select Properties. In the ActionScript tab, check "Export for ActionScript", and give it a class name of, say, Music. Then, to play and stop this clip, you can use this code:
import flash.media.Sound;
// create the music Sound object so that we can start playing
var music : Sound = new Music();
var musicChannel : SoundChannel;
// play the music
// the play() method returns a SoundChannel,
// which you can later use to stop the music
// notice that we first check to make sure musicChannel is null
// if it isn't null, music is already playing, so don't play it twice
if(musicChannel != null) musicChannel = music.play();
// when you switch screens, stop the music
// clear out the channel, so that we know that it is safe to start the music again
musicChannel.stop();
musicChannel = null;
Alternatively, if you play music and sounds by placing them on the timeline, you can stop it by using the Sync setting of the frame. On the timeline, create a keyframe where you switch screens and want the music to stop playing. Select that frame, and drag the sound clip you want to stop onto that frame. In the Properties panel, change the Sync option to Stop. This will cause only the selected sound to stop playing.
Yet another method is to create an empty MovieClip with the sound placed inside of it. Change the Sync setting to Stream, and pad the clip out with empty frames so that it will play the entire clip. Then, if you place this clip on your main menu screen, then it will only play during the main menu. Stream sounds only play the sound for as long as the MovieClip exists and is playing. Compare this to normal Event sounds, which will play the entire sound regardless.
The latter methods are more old-school and movie-centric. If you are programming a game, it would be more appropriate to use the former method to give you more control of the audio in code.

Flash AS3 | Looping sound for each animation set

with University done I've finally had time to go back to practicing my Flash work, and I need some help with getting sound to loop and change depending on what part of the animation is playing.
This is also partly a follow up question to an older one I asked, so look here to get more detail as to where I'm coming from if you don't understand! (I've solved that issue, the current one relates to following up on it!)
Flash AS3 | Finishing current animation set before code is executed
The situation is basic: I have two different scenes, one of a man walking and one of a man running. It loops seamlessly of the man walking until you hit a button, where it finishes the animation then starts looping the run animation. Likewise, hitting the button again, finishes the loop before going back to the looping walk animation. The code for the button is below.
import flash.events.MouseEvent;
Next2.addEventListener(MouseEvent.CLICK, Change_2);
function Change_2(event: MouseEvent): void
{
addEventListener(Event.ENTER_FRAME, enterFrame);
function enterFrame(e:Event):void {
if (currentFrame == 30) {
gotoAndPlay(31);
removeEventListener(Event.ENTER_FRAME, enterFrame);
}
}
}
My issue is trying to get a footstep sound to match up with these animations. So while the man is walking, the 'walking footsteps' sound clip will play and loop alongside the animation, and when the button is pushed and the animation moves into the running animation, the 'running footsteps'' sound will play.
Any help on this would be much appreciated. I'm terrible when it comes to anything audio/code based.
Well u can check about soundChannel. soundChannel can stop() and play() ur audio.
So import ur external sound or use internal one. ur code probably seems like this.
var mySound:Sound = new Sound(new URLRequest("YourSoundPath"));
var sc:SoundChannel = new SoundChannel();
//when u wanna play
sc = mySound.play();
//when u wanna stop
sc = mySound.stop();
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/media/SoundChannel.html
also look this link for more info
If you want to really MATCH the footsteps to the animation (for example, the step sound should play when the player have put his feet down) the only sure way to do that is to place the sound on a different layer where your animation is and set the sound to play as "stream" (if i remember correctly).
Otherwise the animation might be out of sync because of different computer capabilities, current computer or graphics card load etc.
When the sound is set to play as "stream" the flash player is orienting on the sound and drop frames if the graphics are slow to keep the sound and animation in sync

AS3/Flash CS6 - Stop music after Scene?

I'm a beginner in AS3 and Flash CS6.
I tried to search for a solution, but couldn't find anything that would've worked for me.
I have a small game where you must avoid particles coming at you, and as usual, when you hit one, you goto The End scene.
The problem is that when you replay the game from The End screen, the music won't stop, but start again on top of the other one.
I've included my sound from Library -> mysound.mp3 -> Properties -> ActionScript3 -> Export for ActionScript & Export in Frame 1.
Is there a way I could stop the sound from ActionScript?
Is there a way I could stop the sound from ActionScript?
Don't place Sound object on the timeline, control it yourself, It's pretty easy and straightforward.
//Start background music somewhere
var soundFromLibrary: SomeSound = new SomeSound();
var myBackgroundMusic: SoundChannel = soundFromLibrary.play(0, int.MAX_VALUE);
//Now you have reference on background music, stop it
myBackgroundMusic.stop();
If you have the music set on a specific keyframe, then in the properties panel, set it to
Sync: Start
Repeat: 1
And on the frame where you want to stop the music:
Sync: Stop
Repeat: 1

How to put music in individual scenes and have it change when i select a new scene

Alright I've managed to make an almost web page style thing in flash. I have all the coding to navigate the pages finished, but now I'm having the issue of when I change pages my main page music continues while the other pages music begins. I.,m unsure of how to code this. can anyone help? also I already have click sound effects going for my buttons and they seem to be working fine. Don't know if that helps at all. I'm also using flash cs6 and don't want to go to cc, because the removal of the bone tool.
To stop a sound, you will need to use a SoundChannel object when you tell the sound to play. Then, with the reference to the SoundChannel, you can stop the sound before you exit the section.
// save this reference for later so you can stop the sound when you want..
var mySoundChannel:SoundChannel = mySound.play(); // Get a sound channel.
// Call this later
mySoundChannel.stop();
Without a SoundChannel to control it, the sound object will do its default behavior, which is to play to completion.

Flash CS6 AS3 play sound on one frame only, stop when left frame

I have a scene which has a frame for each screen that I want to display to the user. Each frame has a movieclip which contains all the elements for that screen. The first frame's movieclip has frame1 set up with a sound layer. Problem is, when I navigate to a different screen, the music continues to play.
How can I get it to only play whilst the movieclip is visible on the screen? I tried to have an "ENTER_FRAME" listener of the other screens and used SoundMixer.stopAll(); which stopped the music. The only problem is, when I reentered the frame with music, it wouldn't start.
I am using the Sync Setting: Stream.
Flash IDE has a number of different kinds of sounds, the most important being Stream and Event.
It sounds like you're using an Event type sound because the sound continues to play even when you are off the frame. There is no way to stop an Event sound except with SoundMixer.stopAll().
You need to set the sound type to Stream in Flash IDE. Then, place it in a MovieClip and make sure that there enough frames in the clip to last the whole duration of the sound. Then, place that MovieClip in your main scene and it should now stop when you move to a different frame.

How to ENTIRELY remove an flvplayback from stage when going to another flvplayback on another frame?

I'm trying to create an EXE projector using flash 5.5 AS3 where I have a few videos (FLVs) to show (their location is right next to the exe file in the same directory) - each load in a different frame, and all of those videos should also have a full screen option to them. Those are original videos that people WILL want to watch in full screen. It's essential for the experience...
The problem(s) I currently have (after fixing the sound that didn't stop after going to a different video) are hard to describe, but I'll try really hard.
Ok, so when I click the full screen button on a video and watch it in full screen, I will eventually want to exit the full screen, so I click on the same icon at the bottom to exit full screen (or ESC button, it's the same) and then click the navigation button to go to the SECOND FLV's frame to watch the other video. After watching the second video in full screen and then exiting full screen, flash takes me to the FIRST video's frame and that is a big problem. Also, now the button that takes me BACK to the second video's frame won't work. It's like flash is stuck.
I use the Components --> FLVPlayback 2.5 from the componant menu (I don't really know AS3 programming) and I fix its properties in the component parameters.
Also, I don't think that any of the followings are the reason for the bug, but I use these 3 scripts to stop all sound when navigating away from one frame (with an FLVplayback) to
another frame with another FLVplayback:
MyFLV.stop();
SoundMixer.stopAll();
MyFLV.addEventListener(Event.REMOVED_FROM_STAGE,xyz);
function xyz(e:Event):void{
MyFLV.stop();
}
I've found these online where people asked help for the sound bug I described.
The third script was suppose to remove the FLVplayback from the stage before going to another frame, but it works only when NOT GETTING INTO FULL SCREEN. I need something that will COMPLETELY remove the previous video from the stage so after exiting the SECOND viewed video, flash won't take me to a video that from some reason is still in its memory. I have something like 30 videos in my project and I need to remove each and every one of them off of the stage before navigating to the next frame to open a new FLVPlayback.
I tried to add a link to a demo I made with the problem so you can look at it, but it triggered a "oops, something went wrong" error, probably anti spam mechanism...
I would recommend using only one frame and only one flvplayback instance. Otherwise you have to deal with weird bugs like the one you are getting (usually caused by misplaced or forgotten code). Of course, using only one frame requires using more code, but with the number of hard-fixes it looks like you were making for the bugs, you may end up with less code.
Don't worry, I'll walk you through everything!
Reasons to use code (as opposed to multiple frames):
Easier to keep track of:
Know where all your code is so you can easily find and fix any problems.
Make changes more easily
You want to switch an existing video? edit a file reference and you are done.
Want to add a video? no more dragging a new flvplayback instance onto a new frame just add some very simple code and a button and you're done.
More customization
Reasons to use multiple frames (and multiple flvplayback instances):
easier to place visually
Some people find it easier when they have an actual movieclip that they can visually place on the stage
Less code
Here we go:
//import flv library
import fl.video.*;
This allows you to use ActionScript to manipulate the flv player
//video playback code-----------------------//
var myVideo:FLVPlayback = new FLVPlayback();
this creates an instance of FLVPlayback called myVideo (referenced from now on in the code as myVideo)
this next chunk shows many of the customizable features of the flv player. It is not necessary to include them.
//places the video player on stage at x,y
myVideo.x = 115;
myVideo.y = -10;
//uses SkinOverPlayFullscreen.swf for controls
myVideo.skin = "SkinOverPlayFullscreen.swf";
//color of controls
myVideo.skinBackgroundColor = 0x333333;
//hide controls and time it takes controls to fade and reappear (milliseconds)
myVideo.skinAutoHide=true;
myVideo.skinFadeTime=300;
//add the player to the stage
addChild(myVideo);
And now comes the important part. I have made buttons and added them to the stage. I gave each of the buttons a different instance name (box1_btn, box2_btn, and box3_btn). When someone clicks on a button, an "event" will occur.
//button listener code-------------------------//
//when button 1 is clicked throw button 1 event
box1_btn.addEventListener(MouseEvent.CLICK, clicked1);
//when button 2 is clicked throw button 2 event
box2_btn.addEventListener(MouseEvent.CLICK, clicked2);
//when button 3 is clicked throw button 3 event
box3_btn.addEventListener(MouseEvent.CLICK, clicked3);
//play different videos for different buttons---------//
//when button 1 event is thrown
function clicked1($e:MouseEvent):void
{
//play video 1.flv
myVideo.source = "1.flv";
}
//when button 2 event is thrown
function clicked2($e:MouseEvent):void
{
//play video 2.flv
myVideo.source = "2.flv";
}
//when button 3 event is thrown
function clicked3($e:MouseEvent):void
{
//play video 3.flv
myVideo.source = "3.flv";
}
This code will not have any sounds that keep playing because two videos cannot play at the same time in one instance of the player. Nor will it have any mess-ups when you come out of fullscreen because there is only one frame for the video to go back to.
Some possible problems you may run into:
It doesn't work at all:
Make sure you have added an instance of FLVPlayback to the library by adding an instance to the stage from the components menu (window>>components or ctrl+F7) and then deleting it from the stage (it should still appear in the library).
The playback buttons I want aren't showing up:
There is a great explanation of how to use As3 to manipulate FLVPlayback here:
http://www.republicofcode.com/tutorials/flash/as3flvplayback/
find the section about "Applying a Skin to the FLVPlayback Component" and follow it to use an adobe playback skin. If you want to make your own unique skin I would recommend opening and editing one of the pre-made skins. I found mine in
C:\Program Files (x86)\Adobe\Adobe Flash CS6\Common\Configuration\FLVPlayback Skins\FLA\ActionScript 3.0
I hope this helps!
Below would be simplest way to unload the FLVPlayback
removeChild(MyFLV);
it works fine for me
flvPlayBack.stop();
removeChild(flvPlayBack);
stops the sound and removes the playback.
