MP3 Player in AS3

This the code which you may use it to create a MP3 player using AS3. Copy these scripts in a class called Mp3Player and use this class in your flash cs3 as follows.

var player:Mp3Player = new Mp3Player();
player.play('blah.mp3');
or
var player:Mp3Player = new Mp3Player();
player.playlist = ['item1.mp3','item2.mp3'];
player.next();

Current System Time using Timer()

This is about basically how to get your current system time using Timer() function using AS3.

 

For this you need to create four dynamic text boxes and name those as txtHrs, txtMins, txtSecs, and txtDate.

 

Put the following actions in your movie frame and create a class and use these.

 

var time:Timer = new Timer(10);

tm.addEventListener(TimerEvent.TIMER, update);

function update(tevt:TimerEvent):void {

                         var now:Date = new Date();

                         var hr:Number = now.hours;

                         var min:Number = now.minutes;

                         var sec:Number = now.seconds;

                         if (hr > 12) {

                                                  hr -= 12;

                         }

                         txtHrs.text = String(hr);

                         if (min < 10) {

                                                  txtMins.text = “0″;

                         }

                         else {

                                                  txtMins.text = “”;

                         }

                         txtMins.appendText(String(min));

                         if (sec < 10) {

                                                  txtSecs.text = “0″;

                         }

                         else {

                                                  txtSecs.text = “”;

                         }

                         txtSecs.appendText(String(sec));

                         txtDate.text = now.toDateString();

}

time.start();

 

Now test your movie and you can see your system time on your movie display.

Try this!.
