Action Script 3. Timer MM:SS doesn't work

Question

I'm creating app and I need to show game time MM:SS format. But I don't know why timer doesn't wrok It shows 0:00.359 (359 of miliseconds) and not change. Where is the problem? I can't find It. Thank you.

    var timer:Timer; //import flash.utils.Timer;
    var txtTime:TextField;
    var tmpTime:Number;  //this will store the time when the game is started    

//your constructor:
public function MemoryGame()
{
    timer = new Timer(1000); //create a new timer that ticks every second.
    timer.addEventListener(TimerEvent.TIMER, tick, false, 0, true); //listen for the timer tick

    txtTime = new TextField();
    addChild(txtTime);

    tmpTime = flash.utils.getTimer();
    timer.start(); //start the timer
    //....the rest of your code
}

private function tick(e:Event):void {
    txtTime.text = showTimePassed(flash.utils.getTimer() - tmpTime);
}

//this function will format your time like a stopwatch
function showTimePassed(startTime:int):String {
  var leadingZeroMS:String = ""; //how many leading 0's to put in front of the miliseconds
  var leadingZeroS:String = ""; //how many leading 0's to put in front of the seconds

  var time = getTimer() - startTime; //this gets the amount of miliseconds elapsed
  var miliseconds = (time % 1000); // modulus (%) gives you the remainder after dividing, 


  if (miliseconds < 10) { //if less than two digits, add a leading 0
    leadingZeroMS = "0";
  }

  var seconds = Math.floor((time / 1000) % 60); //this gets the amount of seconds

  if (seconds < 10) { //if seconds are less than two digits, add the leading zero
    leadingZeroS = "0";
  }

  var minutes = Math.floor( (time / (60 * 1000) ) ); //60 seconds times 1000 miliseocnds gets the minutes
  return minutes + ":" + leadingZeroS + seconds + "." + leadingZeroMS + miliseconds;
}


//in your you-win block of code:
var score = flash.utils.getTimer() - tmpTime; //this store how many milliseconds it took them to complete the game.

Answer 1

You need not do this.

var time = getTimer() - startTime;

In your code, startTime is already time elapsed due to

showTimePassed(flash.utils.getTimer() - tmpTime);

OR you can call

showTimePassed();

and change time calculation as

var time = getTimer() - tmpTime;

Answer 2

Try

 timer.currentCount

instead of

 flash.utils.getTimer()

It will return the number of times the timer has fired the TIMER-Event.
