I have this code for my volume slider:
var stVolume:SoundTransform=new SoundTransform();
slider.addEventListener(SliderEvent.CHANGE,volslider);
function volslider(ev:SliderEvent):void
{
stVolume.volume=(ev.value/100);
sch1.soundTransform = stVolume;
}
I have many frames with different sound channels. How can I call this function with specific sound channels in each frame like shc2, sch3 and others instead use repeatedly all of function?
Is it possible send SoundChannel name whit eventListener for example:
slider.addEventListener(SliderEvent.CHANGE,volslider(/*something i don't know*/,sch10));
An AudioSource is attached to a GameObject for playing back sounds in a 3D environment. In order to play 3D sounds you also need to have a AudioListener. The audio listener is normally attached to the camera you want to use. Whether sounds are played in 3D or 2D is determined by AudioImporter settings.

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();

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
this is a newer version to a question i have asked before but have not received an answer to.
I am developing a mobile AIR app with many animations and tests have shown that using bitmaps and GPU rendering give the best performance across all mobile models. I receive normal vector animations from the app's artists, and have built a system which loops through these animations at runtime and draws the content into bitmapdatas.
my concern is looping through the movieclip's frames. If I have these lines of code:
for (var i:uint=1; i<mc.totalFrames+1; i++) {
mc.gotoAndStop(i);
bitmapData.draw(mc);
}
I can't be sure the frame got "constructed" before being drawn, and my tests with an Android tablet prove this right - sometimes frames aren't drawn.
This mc is off the display list obviously (we dont need to render to the screen). So is there a way to make sure the frame has been built before drawing it to a bitmapdata? (and waiting for FRAME_CONSTRUCTED, EXIT_FRAME, etc.. is obviously slow and unneeded)
any ideas?
thanx

more info to clarify:
this is a children's book. each page has animations in it. all these animations are vector animations in timelines in FLAs I receive from the devloping artists (not the users).
Every page has an FLA which i publish to a swf.
what i actually do is replace vector animations in loaded SWFs with bitmap version of them.
At app runtime, upon each new page, i load the swf, go though all the animations in it (looping through the content's children) and each movieclip i rasterize into array of bitmapdatas.
My custom "Bitmap Movieclip" places on the displaylist a replcaement bitmap for each movieclip, and on ENTER_FRAME i switch the bitmaps' bitmapdatas from the array.
this gives very hight performance
I'd suggest use a splash screen, and place your MC to be converted to the bitmap to the stage first, then draw to your bitmapData. Several issues had me force to put a DisplayObject being drawn to the stage before actual drawing once already, so this might be a quick fix for you too.
var splashBD:BitmapData=new BitmapData(stage.stageWidth,stage.stageHeight,false,0xffffff);
var splashBM:Bitmap=new Bitmap(splashBD); // draw a thing as needed here
addChild(splashBM);
addChildAt(MC_to_convert,getChildIndex(splashBM));
// then advance it by frames and draw.
sorry MY BAD
waiting for FRAME_CONSTRUCTED is the answer
I've had a problem for a while trying to reset an audio loop to the beginning when loaded into Actionscript with this code i got from the official help forum
var alreadyExecuted:Boolean;
if(!alreadyExecuted){
alreadyExecuted=true;
var s:Sound=new SkaianSpirit();
var sc:SoundChannel=s.play(0,1);
}
What i want it to do, is loop indefinitely while the animation is playing regardless of positioning and whether or not frames have been skipped with buttons etc, but when the end of the animation comes, the track needs to end. At which point, if a button is clicked to send it back to the beginning of the animation, i want it to start the same loop as before.
Currently, it will do the first part, but will not replay.
A couple caveats:
I am not loading it through a url.
I am not using buttons to control audio volume etc. It is to play automatically when the animation starts.
I am a complete and utter novice with Actionscript. I will not know what you're talking about if you lambast me with jargon i won't understand.
I'd highly appreciate the help!
I'm always use addFrameScript function for synchronizing external sounds with animations:
UPD: mc is the name of your animation. Place this code in the place (the first frame of the parent Sprite that holds the animation for instance) where your animation is created.
var s:Sound=new SkaianSpirit();
var sc:SoundChannel;
mc.addFrameScript(1, startSound);
mc.addFrameScript(mc.totalFrames - 1, stopSound);
function startSound():void
{
sc = s.play();
}
function stopSound():void
{
sc.stop();
}
I've created a few buttons in Flash. I'm trying to make it so that if you click one button, the audio starts playing for that button. If you click another button, the active audio stops and the new audio of the button you clicked last start playing.
Any help please?
What you're describing is actually quite easy to do.
First things first, I recommend importing the audio into your Flash project. Alternatively, there is a way to play it directly from an external file. This is beyond the scope of my answer, so if you need help on that, you should post a question specifically covering it.
Assuming you have imported the audio file into your Flash project's library, make an as3 instance of it. (Right click the file in the library, click Properties --> ActionScript [tab] --> [Check] Export for ActionScript & [Enter name in] Class)
Now, create a definition of the sound in your code. (Assuming your two sounds were named "mySound1" and "mySound2" in the Class field of the previous step.)
var mySound1:Sound = new mySound1();
var mySound2:Sound = new mySound2();
Now, define your sound channel.
var mySoundChannel:SoundChannel = new SoundChannel();
There are two alternate ways of stopping one sound and playing another. The first is to create one function that does both every time. The second method is to create two formulas, one for "play" and one for "stop". You will need to decide which method works best for you. I'll use the two-function method below:
function stopSound():void
{
//This stops all sound in the sound channel.
//If there is nothing playing, nothing happens.
mySoundChannel.stop();
}
//In this function, we create an argument that allows us to tell the function
//what sound to we want it to play.
function playSound(soundname:String):void
{
mySoundChannel = this[soundname].play(0, 0);
}
[Note, you can tweak the play() properties to meet your needs, doing things like starting in the middle of the song, or looping it forever. 0,0 starts at the beginning, and doesn't loop. See the documentation for this.]
Now you hook up the event listeners for the buttons. (If you need help with event listeners, read the documentation.)
myButton1.addEventListener(Mouse.CLICK, btn1Click);
myButton2.addEventListener(Mouse.CLICK, btn2Click);
function btn1Click(evt:Event):void
{
stopSound();
playSound(mySound1);
}
function btn2Click(evt:Event):void
{
stopSound();
playSound(mySound2);
}
This should be enough information to get you started. In my game core, I actually have a custom class for dealing with sound playback that gives me the ability to repeat sounds, change volume, and keep sounds from conflicting with each other. I say that to emphasize that you can do quite a bit with the sound class. Do some digging in that documentation for ideas and help.
You may also consider putting a try-catch statement in the playSound function, since it will throw an reference error if you pass a name for a sound that doesn't exist.
I have this custom video player I'm making. I need some way to react when the externally played flv file reaches a certain point in the movie without embedding some extra data on the flv file. I am looking for this because I want to react at the 90%-99% point of the movie because I didn't like the behavior I'm getting when I react when the stream completes playing (I want a bit earlier). How do I achieve this?
I'm surprised Adobe didn't document what is the object structure passed on things like onMetaData and onCuePoint...
You can achieve this with a little math. Position of play head divided by duration multiply by 100.
If value is greater than 90 fire your event.
((p / d) * 100)
You can do this by programmatically setting a cue point based on the length the movie clip, then creating an event listener for it.
var endpoint:Number = flvPlayer.metadata.duration*.95; //95% of the video length
flvPlayer.addASCuePoint(endpoint, "endpoint");
flvPlayer.addEventListener(MetadataEvent.CUE_POINT, registerCuePoints);
function registerCuePoints(myEvent:MetadataEvent) {
if(myEvent.info.name == "endpoint") {
// you've reached your cue point, not something embedded in the video.
}
}
