【原】很有效的　FLASH 声音程序

import flash.events.Event;

import flash.media.Sound;

import flash.media.SoundChannel;

import flash.display.Sprite;

import flash.net.URLLoader;

import flash.display.Loader;

var po:int=0;

var str:String="p.mp3";

var str1:URLRequest= new URLRequest(str);

var str2:Sound= new Sound();

var str3:SoundChannel;

var str4:Boolean= true

str3= new SoundChannel()

str2.load(str1);

a_btn.addEventListener(MouseEvent.MOUSE_DOWN,p1);//播放

b_btn.addEventListener(MouseEvent.MOUSE_DOWN,p2);//暂停

c_btn.addEventListener(MouseEvent.MOUSE_DOWN,p3);//停止

d_btn.addEventListener(MouseEvent.MOUSE_DOWN,p4);

function p1(evt:MouseEvent):void {

 if(str4){

 str3=str2.play(po);

 str4=false

 }

}

function p2(evt:MouseEvent):void {

 str4=true

 

 po=str3.position;

 str3.stop()

}

function p3(evt:MouseEvent):void {

 str4=true

 str3.stop();

 po=0

 

}

function p4(evt:MouseEvent):void {

/*str3.close()*/

}

 随便点键不会产生重复播放的声音
