Play/Pause Toggle for MP3 Player

programming flash
1

Hello,

If anyone has any suggestions on creating a play/pause effect from the actionscript that I am currently using, it would be greatly appreciated! I already have a play/stop toggle button, but would like to turn it into a play/pause button. (You will probably recognize this from the HOT Flash Prof. 8 book, Beyond The Basics.)

:look: Even though the code for next/previous buttons is listed below, I really only need play/pause toggle functionality…and am at a total loss at how to do this.

The actionscript for each instance of the buttons are as follows:

PLAY:
on (rollOver) {
_root.helpBubble.text = “play music”;
}

on (rollOut) {
_root.helpBubble.text = “”;
}

on (release) {
_root.playMusak();
nextFrame();
}

STOP:
on (rollOver) {
_root.helpBubble.text = “stop music”;
}

on (rollOut) {
_root.helpBubble.text = “”;
}

on (release) {
_root.stopMusak();
prevFrame();
}

The actionscript that I am using for the overall flash project is as follows:

//----------------<sound initialization>-------------------\
var curTrackNum:Number = 0;
var bgMusak:Sound;

// autosize some text fields
this.helpBubble.autoSize = “center”;
this.trackInfo.autoSize = “left”;

// load the track info vars
var myMusicLv:LoadVars = new LoadVars();
myMusicLv.load(“vars/track_info.txt”);

//----------------<sound setup>----------------\

function stopMusak() {
delete bgMusak;
}

function playMusak() {
bgMusak = new Sound();
bgMusak.onSoundComplete = function() {
if (curTrackNum == (myMusicLv.totalTracks - 1)) {
curTrackNum = 0;
} else {
curTrackNum ++;
}
stopMusak(); /* change to playMusak(); if want to loop song */
}
bgMusak.onID3 = function() {
trackInfo.text = "artist : " + bgMusak.id3.TCOM + " | track : " + bgMusak.id3.TIT2;
}
bgMusak.onLoad = function(success) {
if (!success) {
trackInfo.text = “Failed to load track.”;
}
}

bgMusak.loadSound("mp3s/mp3-" + curTrackNum + ".mp3", true);

musakProgBar.onEnterFrame = function() {
    bgMusak.setVolume(musakVolume);
    musakVolume = -musakVolumeMC.musakVolumeSliderMC._y * 2;
    // add and modify percentage text
    musakVolumeMC.volumeTxt.text = musakVolume + "%";
    musakVolumeMC.volumeTxt._y = (-musakVolume/2) - 3;
    musakVolumeMC.volumeTxt._alpha = musakVolume;
    var trackD1Prog:Number = _root.bgMusak.getBytesLoaded() / 1000;
    var trackD1Total:Number = _root.bgMusak.getBytesTotal() / 1000;
    var trackD1Percent:Number = Math.round((trackD1Prog/trackD1Total) * 249);
    var trackD1Duration:Number = Math.round((bgMusak.duration/trackD1Percent) * 249);
    musakProgBar.progMaskContainer.progMask._width = trackD1Percent + 9;
    musakProgBar.musakProg._x = Math.round(_root.bgMusak.position/trackD1Duration * 249);
}

}
//----------------</sound setup>----------------\

this.nextTrackBtn.onRelease = function() {

} else {

}
}
