I have a flash video that is short, has sound, and I've got Play Pause and Stop buttons.
Without sound, it works perfectly. It autoplays, you can hit pause and it pauses, and play resumes where it leaves off. Hitting stop goes to an empty frame if someone wants to turn it off.
I have audio inside my library, and would like connect the audio with the same elements. I've been researching for awhile now, and I've not come up with a solution yet, and having a hard time.
Here is my ActionScript code for my currently working buttons:
StopBtn.addEventListener(MouseEvent.CLICK, stopplaying);
function stopplaying(Event:MouseEvent):void {
stop()
}
PlayBtn.addEventListener(MouseEvent.CLICK, startplaying);
function startplaying(Event:MouseEvent):void {
play()
}
CloseBtn.addEventListener(MouseEvent.CLICK, close);
function close(Event:MouseEvent):void {
gotoAndStop(240)
}
You should use Sound and SoundChannel to do this. And for pause you'll have to save the current play position so that you can continue from there:
var audio:Sound = new audioFromLibrary(); //linkage name
var soundChannel:SoundChannel = new SoundChannel();
var audioPosition:Number = 0;
//PLAY:
soundChannel = audio.play(audioPosition);
//PAUSE:
audioPosition = soundChannel.position;
soundChannel.stop();
//STOP:
soundChannel.stop();
I'm making a game with AS3. I would like to put a different music in each background.
So far, I've succeed to start the music when the player enters in a scene. But if he goes out, the music is still playing...(I want the music to stop when the players leave a scene).
I don't understand why the music is still playing.. Here's my code :
public function newBackground(thisBack:String):void{
var room = back.currentBack;
switch (thisBack){
case "maisonExt":
var mySound:Sound = new exterieur ();
mySound.play ();
My mp3 file is named "exterieur.mp3".
If you can think of anything it would be a great help.
Thanks !
You need to stop the music again. If you don't stop it, it will keep on playing :)
When you call .play it will return a SoundChannel which lets you control the playback -- changing position, stopping the playback, and accessing the SoundTransform which lets you control the volume. Here is some example code for you:
public var currentSoundChannel:SoundChannel;
public function newBackground(thisBack:String):void
{
var room = back.currentBack;
if (currentSoundChannel != null)
{
currentSoundChannel.stop()
}
var nextSong:Sound;
switch (thisBack){
case "maisonExt":
nextSong = new exterieur ();
break;
}
currentSoundChannel = nextSong.play();
}
If you want to learn more about sound, I would recommend this tutorial http://gamedev.michaeljameswilliams.com/2009/03/03/avoider-game-tutorial-9/. It's part of a larger tutorial which teaches you many aspects of game making, taking you from novice to capable of creating a game. You should really check that out.
What AS3 code is used to loop a sound using AS3?
This won't give you perfect, gapless playback but it will cause the sound to loop.
var sound:Sound = new Sound();
var soundChannel:SoundChannel;
sound.addEventListener(Event.COMPLETE, onSoundLoadComplete);
sound.load("yourmp3.mp3");
// we wait until the sound finishes loading and then play it, storing the
// soundchannel so that we can hear when it "completes".
function onSoundLoadComplete(e:Event):void{
sound.removeEventListener(Event.COMPLETE, onSoundLoadComplete);
soundChannel = sound.play();
soundChannel.addEventListener(Event.SOUND_COMPLETE, onSoundChannelSoundComplete);
}
// this is called when the sound channel completes.
function onSoundChannelSoundComplete(e:Event):void{
e.currentTarget.removeEventListener(Event.SOUND_COMPLETE, onSoundChannelSoundComplete);
soundChannel = sound.play();
}
If you want the sound to loop many times with a flawless, gapless playback, you can call
sound.play(0, 9999); // 9999 means to loop 9999 times
But you still would need to set up a soundcomplete listener if you want infinite playback after the 9999th play. The problem with this way of doing things is if you have to pause/restart the sound. This will create a soundChannel whose duration is 9999 times longer than the actual sound file's duration, and calling play(duration) when duration is longer than the sound's length causes a horrible crash.
var sound:Sound = whateverSoundYouNeedToPlay;
function playSound():void
{
var channel:SoundChannel = sound.play();
channel.addEventListener(Event.SOUND_COMPLETE, onComplete);
}
function onComplete(event:Event):void
{
SoundChannel(event.target).removeEventListener(event.type, onComplete);
playSound();
}
import flash.media.Sound;
import flash.media.SoundChannel;
var mySound:Sound = new Bgm(); //Bgm() is the class of the internal sound which can be done in the library panel.
playSound();
function playSound():void
{
var channel:SoundChannel = mySound.play();
channel.addEventListener(Event.SOUND_COMPLETE, onComplete);
}
function onComplete(event:Event):void
{
SoundChannel(event.target).removeEventListener(event.type, onComplete);
playSound();
}
This works perfectly.
To expand on #scriptocalypse's gapless playback a bit:
The problem of not having proper gapless playback comes from mp3 including information about the file in either the head or the tail of the file (id3 tags etc), hence the small pause when you try to loop it. There are a few things you can do depending on your situation.
Ignore it, just play as normal, with a small pause at the end of every file. You can also try and mask it with another sound (a beat drop yo), or fade out and fade in.
If your sounds are embedded, and not streaming, then create a fla file, drag your mp3 in there, and set them to export (the same way you'd add a linkage name for a MovieClip etc). It seems that when you export sounds like this, Flash takes the delay into account, or strips it out when it creates the Sound object. Either way, you can just do a simple play() passing the loops that you want for a gapless playback (I've found using a loops parameter is better than waiting on the SOUND_COMPLETE event and playing it again).
You can try some of the ogg libraries to use .ogg files instead of .mp3. A simple google search for "as3 ogg lib" will turn up what you need. Personally, I found them a bit awkward to use, and I couldn't afford the overhead added (as opposed to mp3 decoding, which is done in the player).
If your mp3 files are streaming, then the only way to get gapless playback is to layer them. Determine the gap (depending on what you used to encode them, it'll be different - my files has a gap of about 330ms), and when you reach it, start playing the overlay. It's a proper pain if you're doing fading, but when it works, it works quite nicely. Worst case scenario, you end up with situation (1)
I guess this what you looking for in case the voice/music file is in the library:
var mysound:my_sound = new my_sound();
mysound.play(0,2); // this will repeat the sound 2 times.
This appears to have worked for me:
var nowTime:Number = (new Date()).time;
var timeElapsed:Number = nowTime - _lastTime;
_lastTime = nowTime;
_musicTimeElapsed+=timeElapsed;
if(_musicTimeElapsed >= _musicA.length - GAP_LENGTH)
{
_musicTimeElapsed = 0;
_musicA.play(0);
}
The other answers are great, however if you do not want to use code (for whatever reason), you can put the sound in a movieclip, set the sound property to "Stream", and then add as many frames as you like to the movie clip to ensure it plays fully.
This, of course, is a less preferred way, but for animators I'm sure it may be preferable in some situations (for example when synced with mouth animations that the animator wants looped).
this work for me :
import flash.media.Sound;
import flash.media.SoundChannel;
var soundUrl:String ="music.mp3";
var soundChannel:SoundChannel = new SoundChannel();
var sound:Sound = new Sound();
sound.load(new URLRequest(soundUrl));
soundChannel = sound.play();
soundChannel.addEventListener(Event.SOUND_COMPLETE,onComplete);
function onComplete(e:Event):void{
sound = new Sound();
sound.load(new URLRequest(soundUrl));
soundChannel = sound.play();
soundChannel.addEventListener(Event.SOUND_COMPLETE,onComplete);
}
I have a website in ActionScript 3 that has lots of FLV animations that happen when you press buttons. Right now this is how I have it set up.
in AS3,
im loading FLv's (which are animations I exported in FLV form from After Effects)
with net stream. I have a timer set up for the same amount of length of time that the animations (FLV's) play and when the timer stops it calls a function that closes the stream, opens a new one and plays another video. The only problem I noticed using timers is that if the connection is slow and (animation)stops for a second, the timer keeps going, and calls the next flv too early.
Does anyone know a way to load a flv, or swf for that matter, at the end of play of the flv? so that the next FLV will always play at the end of the run time of the previous FLV, rather than using timers?
im thinking onComplete but I don't know how to implement that!?
Sequential playing is pretty easy to achieve with the OSMF framework, you should check it out. Google "osmf tutorials" and you should find a few tutorials online.
The framework is fairly recent, but it looks like it may become the de facto solution for media delivery in Flash as it's not limited to video but also audio & images.
As a developer you won't have to bother with the NetStream & NetConnection classes. Developing video solutions , as well as audio & images solutions should be streamlined and easier to handle. Only limitation is that it requires Flash 10
Here's some code for checking when a FLV ends with NetStream. I just provide snippets as I assume you got the FLV up and running already.
//create a netstream and pass in your connection
var netStream:NetStream = new NetStream(conn);
//add callback function for PlayStatus -event
var client : Object = {};
client.onPlayStatus = onPlayStatus;
netStream.client = client;
//attach your NetStream to the connection as usual
//---
//function that gets called onPlayStatus
function onPlayStatus(info : Object) : void {
trace("onPlayStatus:" +info.code + " " + info.duration);
if (info.code == "NetStream.Play.Complete") {
//play the next FLV and so on
}
}
EDIT: With your example code it will look something like this.
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
var listener:Object = new Object();
listener.onMetaData = function(md:Object):void{};
listener.onPlayStatus = function(info : Object) : void {
trace("onPlayStatus:" +info.code + " " + info.duration);
if (info.code == "NetStream.Play.Complete") {
//play the next FLV and so on
}
};
ns.client = listener;
vid1.attachNetStream(ns);
const moviename1:String = "moviename2.flv";
const moviename1:String = "moviename3.flv";
var movietoplay:String = "moviename.flv";
ns.play(movietoplay);
I have the following piece of code:
var song:Sound;
var sndChannel:SoundChannel;
var context:SoundLoaderContext = new SoundLoaderContext(2000);
function songLoad():void {
song.load(new URLRequest(songs[selected]),context);
sndChannel = song.play();
}
Now I want to be able to check if the song is buffering or not. Is there a way to do this? Or should I approach it differently?
Seems like you could use the isBuffering property of the Sound object.
Maybe you could check it periodically with a Timer or an Event.EnterFrame listener, as long as the sound has not been completely downloaded (i.e. until Event.COMPLETE fires). After that point, it makes no sense to check isBuffering, for obvious reasons, so you could remove the Timer or EnterFrame.
