Although there are many countdown examples available on the web, I couldn’t find a decent count up timer for my game Aidan Junior. So I decided to create one myself and post it for you to view and download.
So, lets get started:
var timerCount:int = 0;
Firstly, we create a simple timer with a tick delay of 100 milliseconds.
We add an event listener to it and declare a variable that we’ll use later to store the elapsed time.
timerCount += 100;
This handler increments the timerCount with the elapsed 100 milliseconds and calls the toTimeCode function.
Almost there, now let’s take a look at the last step.
//creating a date object using the elapsed milliseconds
var time:Date = new Date(milliseconds);
var minutes:String = String(time.minutes);
var seconds:String = String(time.seconds);
var miliseconds:String = String(Math.round(time.milliseconds)/100);
//add zero if neccecary, for example: 2:3.5 becomes 02:03.5
minutes = (minutes.length != 2) ? '0'+minutes : minutes;
seconds = (seconds.length != 2) ? '0'+seconds : seconds;
//display elapsed time on in a textfield on stage
timer_txt.text = minutes + ":" + seconds+"." + miliseconds;
And that’s it! I simply converted the elapsed time into minutes, seconds and milliseconds and displayed in on stage.
Feel feel to download and use the .fla file.
