LSound(LWebAudio) Class
This class creates a LSound object.
When the browser does support Web Audio Api and set LGlobal.webAudio = true(default is true), LSound will automatically inherit LWebAudio object.
When LSound inherited LWebAudio, the audio files can be loaded without the click event, but playing audio must in clicke event.
When LSound inherited LWebAudio, allow multiple audio files to play at a time.
Constructor
LSound(LWebAudio)
()
public
Example:
var backLayer;
var sound;
function main () {
backLayer = new LSprite();
addChild(backLayer);
sound = new LSound();
......
var url = "./sample.";
sound.load(url+"mp3,"+url+"ogg,"+url+"wav");
sound.addEventListener(LEvent.COMPLETE,loadOver);
}
function onup (e) {
......
sound.play();
}
function loadOver (e) {
backLayer.addEventListener(LMouseEvent.MOUSE_UP,onup);

Methods
addEventListener
-
type -
listener
Registers an event listener object with an LEventDispatcher object so that the listener receives notification of an event. You can register event listeners on all nodes in the display list for a specific type of event, phase, and priority.
After you successfully register an event listener, you cannot change its priority through additional calls to addEventListener(). To change a listener's priority, you must first call removeListener(). Then you can register the listener again with the new priority level.
If you no longer need an event listener, remove it by calling removeEventListener(), or memory problems could result.
Parameters:
-
typeStringThe type of event.
-
listenerFunctionThe listener function that processes the event.
callParent
-
functionName -
arguments
call the method of parent。
Parameters:
-
functionNameStringfunction's name
-
argumentsArrayFixed value : arguments
Example:
function funA(){
LExtends(this,LObject,[]);
}
funA.prototype.myName = function(){
return "AAA";
}
function funB(){
LExtends(this,funA,[]);
}
funB.prototype.myName = function(){
return "BBB";
}
function funC(){
LExtends(this,funA,[]);
}
funC.prototype.myName = function(){
return this.callParent("myName",arguments);
}
LInit(1000/50,"legend",800,150,main);
function main(){
LGlobal.setDebug(true);
var objB = new funB();
trace(objB.myName());//BBB
var objC = new funC();
trace(objC.myName());//AAA
}close
()
public
Close the currently playing audio.
dispatchEvent
-
event
Dispatches an event into the event flow. The event target is the LEventDispatcher object upon which the dispatchEvent() method is called.
Parameters:
-
eventLEvent | StringThe Event object that is dispatched into the event flow. If the event is being redispatched, a clone of the event is created automatically. After an event is dispatched, its target property cannot be changed, so you must create a new copy of the event for redispatching to work.
Returns:
A value of true if the event was successfully dispatched. function MyEventObject(){ var self = this; LExtends(self,LSprite,[]); self.graphics.drawRect(1,"#000000",[0,0,100,100],true,"#000000"); self.graphics.drawRect(1,"#FF0000",[100,0,100,100],true,"#FF0000"); self.addEventListener(LMouseEvent.MOUSE_UP,self.onclick); self.addEventListener(MyEventObject.CLICK_LEFT,function(event){ trace("dispatchEvent"); }); self.addEventListener(MyEventObject.CLICK_RIGHT,function(event){ trace("dispatchEvent event.name = " + event.name); }); } MyEventObject.CLICK_LEFT = "click_left"; MyEventObject.CLICK_RIGHT = "click_right"; MyEventObject.prototype.onclick = function(event){ var self = event.clickTarget; if(event.selfX < 100){ self.dispatchEvent(MyEventObject.CLICK_LEFT); }else{ var event = new LEvent(MyEventObject.CLICK_RIGHT); event.name = "LEvent Test"; self.dispatchEvent(event); } }
getCurrentTime
()
Int
public
Get the time of reproducing.
Returns:
the time of reproducing.
getVolume
()
Float
public
Get the volume of media.
Returns:
the volume.
hasEventListener
-
type
Checks whether the LEventDispatcher object has any listeners registered for a specific type of event. This allows you to determine where an LEventDispatcher object has altered handling of an event type in the event flow hierarchy.
Parameters:
-
typeStringThe type of event.
Returns:
A value of true if a listener of the specified type is registered; false otherwise.
load
-
url
Initiates loading of an external sound file from the specified URL.
To support different browsers, you can look like this
medio.load("medias/a.mp3,medias/a.wav,medias/a.ogg");
Parameters:
-
urlStringA URL that points to an external sound file.(Can also use a ArrayBuffer or AudioBuffer)
play
-
startTime -
loops
play the audio file.
Parameters:
-
startTimeFloatThe initial position in milliseconds at which playback should start.
-
loopsIntDefines the number of times a sound loops back to the startTime value before the sound channel stops playback.
playSegment
-
startTime -
segment -
loops
play segment of audio.
Parameters:
-
startTimeFloatThe initial position in milliseconds at which playback should start.
-
segmentFloatlength。
-
loopsIntDefines the number of times a sound loops back to the startTime value before the sound channel stops playback.
playTo
-
startTime -
endTime -
loops
play segment of audio.
Parameters:
-
startTimeFloatstart time.
-
endTimeFloatend time.
-
loopsIntDefines the number of times a sound loops back to the startTime value before the sound channel stops playback.
removeAllEventListener
()
public
Removes all the listeners from the LEventDispatcher object.
removeEventListener
-
type -
listener
Removes a listener from the LEventDispatcher object. If there is no matching listener registered with the LEventDispatcher object, a call to this method has no effect.
Parameters:
-
typeStringThe type of event.
-
listenerFunctionThe listener object to remove.
setVolume
-
value
Set the volume of media.
Parameters:
-
valueFloatthe volume。
