i'd like to convert this actionscript 2 instruction:
button_btn.onRelease = function():Void
{
getURL('javascript:shrinkSkinOverlayDiv()');
}
to an actionscript 3 one.At the moment i'm using adobe flash-cc which doesn't support actionscript 2 actions anymore. Since i'm really noob with flash, i need some help (accepted a work from my boss which i can't even accomplish :P).
For your button, use addEventListener() to listen for MouseEvent.CLICK events.
To call a JavaScript function, use ExternalInterface.call().
import flash.events.MouseEvent;
import flash.events.Event;
import flash.external.ExternalInterface;
button_btn.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(event:Event):void {
ExternalInterface.call("shrinkSkinOverlayDiv");
}

Just looking for some advice and hoping someone can point me in the right direction.
I'm trying to create a Flash MP3 player that can play music stored on DropBox. Never used ActionScript before so kind of learning as I go...
From what I've read so far, I need to use URLRequest to get the link to the mp3 file, then use the Sound object to load the file and play it. However, when I test my SWF file I don't get audio. I've also been reading about URLSream and NETstream, but not sure how to use that with the Sound object. I'm not 100% sure if I'm using Sound correctly, and given that this is pretty old technology now, I'm struggling to find decent tutorials.
Here's the code I've been trying:
package {
//Dependencies
import flash.display.MovieClip;
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.net.URLRequest;
import flash.net.URLStream;
import flash.display.*;
import flash.events.*;
import flash.net.*;
import flash.media.*;
//Class code
public class soundObject extends MovieClip {
//Variables
var mySong:Sound = new Sound();
//Init Code here
public function soundObject() {
var myRequest:URLRequest = new URLRequest("https://www.dropbox.com/s/[dropboxurl]/T-U-R-T-L-E%20POWER.mp3?dl=0")
mySong.load(myRequest);
mySong.addEventListener(Event.COMPLETE, onSoundLoad);
}
private function onSoundLoad(e:Event): void
{
mySong.play();
}
}
}
So I figured it out guys... and surprise, surprise, it was something rather simple.
In publish settings, I had it set to 'local only'. When I changed this 'network only' the link started to magically work.
Thanks for the help. Got there in the end :D
EDIT: And just in case, I did also have change ?dl=0 to ?dl=1
Alright, I'm a total noob in flash as3 so this must be very easy to solve I guess. I'm making a soundboard with recorded voices in flash cs6, very simple: 1 frame, ten buttons, each button makes a different sound. The problem is the overlapping of these sounds, so what I need is that when I press one button the other sounds stop playing. anyone please?
See the play() method documentation in the Sound class, it returns a SoundChannel object, which has a stop() method.
So you could do it like that (schematically) :
var currentChannel:SoundChannel;
button1.addEventListener(MouseEvent.CLICK, onButtonClick);
button2.addEventListener(MouseEvent.CLICK, onButtonClick);
button3.addEventListener(MouseEvent.CLICK, onButtonClick);
function onButtonClick(event:MouseEvent):void
{
/* provided you have implemented selectSoundByButton func somewhere */
const sound:Sound = selectSoundByButton(event.currentTarget);
if (currentChannel) {
currentChannel.stop();
}
currentChannel = sound.play();
}
More detailed description:
Let's say you want to create yet another fart button application in flash. That's what you have to do:
Create a button symbol, add it to stage and give it an instance name in properties tab. Let's call it myButton
Add the sound to library with file->import
Export this sound to actionscript. Right click on a sound in library, check "Export for actionscript", "export in frame 1" on "actionscript tab". Fill "Class" input with a desired class name for a sound (e.g. MySound)
Then you have to trigger the sound playback on your button click. So you should put the following code to the first frame of your flash clip:
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.events.MouseEvent;
var currentChannel:SoundChannel;
const mySound:Sound = new MySound();
function onClick(e:MouseEvent):void {
if (currentChannel) {
currentChannel.stop();
}
currentChannel = mySound.play();
}
myButton.addEventListener(MouseEvent.CLICK, onClick);
Add this to your code on each button before playing a sound:
SoundMixer.stopAll();
If you're adding actions directly from the timeline in Adobe Flash, there's no need to import the class. If you're working from an IDE like FlashDevelop or FlashBuilder, add this code to the beginning (after Package {):
import flash.media.SoundMixer;
Happy coding!
Edit: More info on the SoundMixer class
I am at the moment trying to create an interactive movie, structured so that each keyframe in the timeline contains a movieclip navigated to using buttons inside the movieclips, with the appropriate code inside the main timeline.
The problem right now is that when you access the movieclip inside frame 3, the sound from frame 2 also plays simultaneously. After doing some research i found that this appears to be a bug with flash itself, and most of the time is dealt with using SoundMixer.stopAll();. Sadly, i have no idea how to use it to kill the sound from frame 2 when only frame 3 is accessed.
I know that when accessing frame 2 instead, only frame 2 is played, which should mean that flash basically goes through all frames on the way to the frame you are supposed to go to.
This is the limited code i am using at the moment:
Frame 1:
import flash.events.MouseEvent;
import flash.display.SimpleButton;
import flash.media.SoundMixer;
stop();
var soundVar:int = 0;
var Choice1F:SimpleButton;
var Choice1R:SimpleButton;
this.Val1.Choice1F.addEventListener(MouseEvent.CLICK, function(me:MouseEvent):void{buttonHandler(me, 2)});
this.Val1.Choice1R.addEventListener(MouseEvent.CLICK, function(me:MouseEvent):void{buttonHandler(me, 3)});
function buttonHandler(e:MouseEvent, Value:int): void{
SoundMixer.stopAll();
soundVar = Value;
this.gotoAndPlay(Value);
}
Frame 2:
import flash.media.SoundMixer;
stop();
if(soundVar == 3){
SoundMixer.stopAll();
}
Frame 3 simply contains a stop(); statement. The code in frame 2 was a futile attempt from me to make it kill the sound on its way to frame 3. Hopefully, you guys can think of a better solution, if one even exists.
The correct structure of the project assumes that you control the playback of music and sounds with a special instance of custom class. And timeline you use only gave him command when and what to do.
One SoundChannel and couple of Sound's will do the trick.
You could use this one
package src.utils{
import flash.media.Sound;
import flash.media.SoundChannel;
import flash.net.URLRequest;
public dynamic class BackgroundMusicPlayer extends Object{
public var playlist;
public var sndChannel;
private var ID;
public function BackgroundMusicPlayer(srcList:Array){
playlist=[];
for(var i=0;i<srcList.length;i++){
var src= new URLRequest(srcList[i]);
var newSound = new Sound(src);
playlist.push(newSound);
}
}
public function playMusic(id){
if (sndChannel!=undefined) {
sndChannel.stop();
}
sndChannel = playlist[id].play();
ID=id;
sndChannel.addEventListener("soundComplete",replayListener);
}
public function replayListener(e){
sndChannel = playlist[ID].play();
}
}
}
import class to you timeline, create instance passing him files list
var musicPlayer = new BackgroundMusicPlayer("music1.mp3","music2.mp3");
And then you want start some sound, call
musicPlayer.playMusic(0);
If you want use imported to project sounds, just share them to actionscript, give them class names and slightly modify given class constructor
public function BackgroundMusicPlayer(srcList:Array){
playlist=[];
for(var i=0;i<srcList.length;i++){
playlist.push(srcList[i]);
}
}
So your instance creation now should be
var musicPlayer = new BackgroundMusicPlayer(new MySound1(),new MySound2());
I have a game that I've made that runs in two files, one the preloader and one the swf. When I use these two files together they work fine, however some flash portals require only one SWF, so I'm trying to find the shortest-path way to convert it to use only one.
The game swf uses a Document Class that includes the package, class constructor, and tons of functions, and runs fine. I have lots of movieclips on the stage that I refer to in my code. The code is something like this (abridged):
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
...
public class Game extends MovieClip {
var EnemyArray:Array;
var HeroArray:Array;
...
public function Game() { // class constructor
EnemyArray = new Array();
addEventListener(Event.ENTER_FRAME,onEnterFrame);
mainRestartButton.addEventListener(MouseEvent.CLICK, RestartLevel);
...
}
public function KeyPressed(event:KeyboardEvent):void
{
if (event.keyCode == Keyboard.SPACE)
{
attack();
...
}
} // End of class
} // End of package
I also have another swf, my preloader, which has the following code in frame 1:
import flash.display.Loader;
import flash.net.URLRequest;
import flash.events.ProgressEvent;
import flash.events.Event;
var myLoader:Loader = new Loader();
myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onLoading);
var myURL:URLRequest = new URLRequest("Game.swf");
myLoader.load(myURL);
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onLoading(event:ProgressEvent):void {
var loaded:Number = event.bytesLoaded / event.bytesTotal;
percent_txt.text = "Loading: " + (loaded*100).toFixed(0) + "%";
}
function onComplete(event:Event):void {
myLoader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, onLoading);
myLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, onComplete);
this.addChild(myLoader);
}
I've been through the gamut of solutions online and none of them seem to work with the way that my code is set up, such as: How to create Preloader in AS3
I tried his option 1 by taking all the code in my Document Class other than the package and constructor and pasted it into frame 2. However it returns "Error #1009: Cannot access a property or method of a null object reference." for any references to items on the stage, such as:
mainRestartButton.addEventListener(MouseEvent.CLICK, RestartLevel);
As he mentions, "This works well if you organized your project in a way that the most of the assets (images, etc) are in the Flash IDE Library and are not loaded on the first frame (you can check that in each library item's properties)." My project is NOT organized in such a way.
What is the easiest way for me to reorganize my FLA/code so they can have a preloader in a single swf?
Thanks so much for your time and help!
I use FlashDevelop (no FLAs) so I'm not sure if it'll work for you but I use the solution described here.
i have tried to use a timer in the as3 console from FlashFirebug addon but it doesn't work (have tried several combinations). The timer code was this:
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.display.Sprite;
var myTimer = new Timer(1000, 2);
myTimer.addEventListener(TIMER, timerHandler);
myTimer.start();
function timerHandler(event:TimerEvent){trace("timerHandler: ");}
//but it gives this error:
Error #1034: Type Coercion failed: cannot convert r1.deval.rt::FunctionDef#50ef781 to Function.
//also have tried with setInterval with this code:
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.display.Sprite;
import flash.utils.setInterval;
function d(){trace("cc");}
setInterval(d, 2000);
//but console error says:
Error: Call to a possibly undefined method.
//probably need to import something. tried tho import "import flash.utils.setInterval;" but gives this error:"Error: You must import the class before being able to instantiate it. Ex. import flash.display.MovieClip;"
Can you help me on This? timer or setInterval functions?
Thanks,
John
I'm not sure about the error message you're getting, but you do have an error in your code at the point at which you assign the event listener for your timer. You need to access the event name constant from the TimerEvent class like so:
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.display.Sprite;
var myTimer = new Timer(1000, 2);
myTimer.addEventListener(TimerEvent.TIMER, timerHandler);
myTimer.start();
function timerHandler(event:TimerEvent){trace("timerHandler: ");}
There's a decent explanation here on the advantages of using the ActionScript 3.0 Timer class over setInterval.
Well, looks like there is no way to achieve this. FlashFirebug uses D.eval library and I can't find that it supports timers or intervals right now.
I'm not sure you've sorted it yet but it looks like:
var num:int = setInterval(d, 2000);
and if you import import flash.utils.clearInterval; you can stop it like:
clearInterval(num)
The problem is on this line:
myTimer.addEventListener(TIMER, timerHandler);
It should be:
myTimer.addEventListener(TimerEvent.TIMER, timerHandler);
// add this ^^^^^^^^^^^
This is quite old. But answering it to help anyone in the future.
FlashFirebug 4.8.0 which is still on the approval queue (at the time of answer) should enable you to inject an SWF file inside the running SWF.
That would allow you to use full AS3 capabilities when you hit limitations with the console.
