Visual Countdown Timer

I'm working on my first J2ME project, and I'm trying to figure out how best to create a visual countdown timer. In this application, the user is given a little 'mission' that must be solved. Some missions are timed, and the device must be able to display how much time is left in the mission.
I need the timer to stay on the screen (preferrably the top) even though the user may be scrolling through text to be read, or even making selections (List, Choice, or Textfields). Basically, think of the Ticker (from the bundled Stocks demo), but instead of scrolling static text continuously, I want it to display a timer, countling down from some time (e.g. 10 minutes) and updating (9:59, 9:58, ..., 0:03, 0:02, 0:01) fairly frequently (if not every second).
Is the source to the Ticker 'widget' available someplace?
Also, does anyone have any suggestions how to best do this keeping resource usage as low as possible???
Thanks in advance,
Christian ([email protected])

hmm, always visible...
you could try removing/adding a Command once a second, with its label as the time ;]
pretty ugly way of doing it, but the only way if your dealing with Form's.

Best way to implement a countdown timer for a turn based LCCS game

Hello,
I am trying to build a turn based game and sketching out the high level map, so I can focus my efforts towards the direction I should be digging.
One thing I have not seen much in the sample apps is how a turn based game is best handled.
For example, a countdown timer. Should it be a shared property? Or a Baton which is supposed to manage workflows and has a timeout property?
Or, should I forget those two, and time this on the server, although if it would become popular keeping track of all the times in the rooms would cost an arm and leg. Would love to hear some best practices on this.

good idea.
Which one or all of them?

How can I make a countdown timer using After Effects

I'd like to make a video that has a timer that counts down one second at a time. I need one starting at 5:00 (five minutes). Is there a way to easily do this in After Effects without having to manually change the text every second?
Thanks.

I'm glad that you found a solution, but I thought that you might appreciate a suggestion of another approach.
Colin Braley provides a tutorial and example project on
his website that show how to use an expression on the Source Text property to animate text to overcome some of the limitations of the Numbers effect.
There's a similar example in the
"Example: Animate text as a timecode display" section of After Effects Help.
Here are some Community Help searches that can lead you to some ideas, too:

Countdown Timer Error Msg: "Warning: 1090: Migration issue"

Hey folks,
New to Flash here (using CS3), trying to create a countdown
timer.
Following is the error message I receive when trying to test
the
movie:
"Warning: 1090: Migration issue: The onEnterFrame is not
triggered
automatically by Flash Player at run time in ActionScript
3.0. You
must first register this handler for the event using
addEventListener
( 'enterFrame', callback_handler).
Does anyone know what this means? And please "dumb it down"
for this newbie. :)
Following is the actionscript I'm using:
this.onEnterFrame = function() {
var today:Date = new Date();
var currentYear = today.getFullYear();
var currentTime = today.getTime();
var targetDate:Date = new Date(2007,5,10);
var targetTime = targetDate.getTime();
var timeLeft = targetTime - currentTime;
var sec = Math.floor(timeLeft/1000);
var min = Math.floor(sec/60);
var hrs = Math.floor(min/60);
var days = Math.floor(hrs/24);
sec = String(sec % 60);
if (sec.length < 2) {
sec = "0" + sec;
min = String(min % 60);
if (min.length < 2) {
min = "0" + min;
hrs = String(hrs % 24);
if (hrs.length < 2) {
hrs = "0" + hrs;
days = String(days);
var counter:String = days + ":" + hrs + ":" + min + ":" +
sec;
time_txt.text = counter;
Thanks in advance!!!

It just means that you can't do things the "old" way. You
have to use the
AS3 event model, like so:
this.addEventListener("enterFrame", enterFrameHandler);
function enterFrameHandler(evt:Event) {
var today:Date = new Date();
var currentYear = today.getFullYear();
var currentTime = today.getTime();
var targetDate:Date = new Date(2007,5,10);
var targetTime = targetDate.getTime();
var timeLeft = targetTime - currentTime;
var sec = Math.floor(timeLeft/1000);
var min = Math.floor(sec/60);
var hrs = Math.floor(min/60);
var days = Math.floor(hrs/24);
sec = String(sec % 60);
if (sec.length < 2) {
sec = "0" + sec;
min = String(min % 60);
if (min.length < 2) {
min = "0" + min;
hrs = String(hrs % 24);
if (hrs.length < 2) {
hrs = "0" + hrs;
days = String(days);
var counter:String = days + ":" + hrs + ":" + min + ":" +
sec;
time_txt.text = counter;

Javascript countdown timer not working in Safari

Years ago I copied a Javascript for a countdown timer and it has been working on my website ever since in both Safari and Firefox. I have been working on updating my site and suddenly it stopped working in Safari, but still works in Firefox. Obviously, I'd like it to work in everyone's browser if possible. I've created a page which only has the countdown timer on it. Can anyone tell me what I need to do to get it to work in Safari?
The test page where you can see this is: http://hyperflite.com/countdowntest.html
TIA

Hi,
Is there any reason for the numerous body tags in there?
<pre><body onload="doCountdown();">
<body>
<body ... >
</pre>
I don't have Safari here to test with, but I wouldn't have thought they were helping matters

5 minute countdown timer with 3d extrusion for AE CC 5:00

dear AE Family,
Total Newbie here looking to make a 3d countdown timer in after effects CC. I know how to use the effect to make the standard timer. But I want to make the
3d extrusion 5:00 which looks much better. My CC came with cinema 4d lite but cant seem to put them together.
PS I really need it to look like 5:00 4:59, to 0:00 . 3d extrusion.
Thanks in advance, much appreciated.

Have you gone though Getting Started with After Effects?
Have you seen the Basic Workflow series?
Be aware that if you want extruded text with Ray-traced rendering you are going to be in for long render times even with a compatible Cuda card installed and extremely long render times without one.
The easiest way to make a countdown timer that will work with extruded text is to Google Countdown Timer After Effects and then look for expressions. You will find this popular universal timer expression from Dan Ebberts: Dan Ebberts's Expressioneering Design Guide
Get that far and get back to us with your problems.
BTW, there are other ways to mimic 3D extrusions and simple layer effects like Bevel and Emboss or the effect Bevel Alpha that may meet your design idea.

How can I create an animated countdown timer?

Is there a way to create an animated countdown timer in Adobe Fireworks (animated gif)?
Thank you

In the Edit workspace, place the images you want to appear in each frame of the animation on separate layers of the Layers panel. For example, to create an animation of an eye blinking, you would place an image of the open eye on one layer, and an image of the closed eye on another layer.
Choose File > Save for Web.Note: If your image has multiple layers, you can also open the Save For Web dialog box from the Save As dialog box by choosing CompuServe GIF Format and selecting Layers As Frames.
Optimize the image in GIF format.
Select Animate.
Set additional options in the Animation section of the dialog box:
Loop Continuously repeats the animation in a web browser.
Frame Delay Specifies the number of seconds that each frame is displayed in a web browser. Use a decimal value to specify fractions of a second. For example, use .5 to specify half a second.

How do i add a countdown timer in as3 that starts when the program begins?

I also want it to remove everything that is on the stage when it reaches 0 and produce a Game Over screen.

import flash.events.TimerEvent;
import flash.utils.Timer;
var countdown:Timer = new Timer (1000,TARGET_TIME);
//after 60 Seconds every DisplayObject will be removed from stage
const TARGET_TIME:int = 60;
countdown.addEventListener(TimerEvent.TIMER, tick);
countdown.addEventListener(TimerEvent.TIMER_COMPLETE, gameOver);
function tick(e:TimerEvent):void {
    //this will count upwards 1.2.3.4....
    trace(e.currentTarget.currentCount);
function gameOver(e:TimerEvent):void {
    // this function will remove all DisplayObjects from your Stage
    // starting from the top
    //It will not remove shapes or anything the user might have drawn on the stage
    //just things that are accessible to ActionScript (Sprites, MovieClips)
    for (var i:int = this.numChildren-1 ; i >= 0; i--) {
        removeChildAt(i);
//countdown will start only if you call it explicitly
countdown.start();

How to create countdown timer with sound

Any ideas on how to create a minute and seconds countdown timer that would play a sound and then redirect you to another page?

Hi,
There is no out of the box solution to do so in Muse at the moment. If you can get your own code, you can add it to your site using "Insert HTML" feature.

Countdown Timer

Can anyone gve me any advice on how to make a countdown timer
in actionscript 3?
I have tried several ways and have so far been
unsucessful.

Here's something simple:
var endDate:Date = new Date(2012, 11, 21);
var t:Timer = new Timer(500);
t.addEventListener(TimerEvent.TIMER, msLeft);
t.start();
function msLeft(e:TimerEvent){
var now:Date = new Date();
var ms = endDate.valueOf() - now.valueOf();
var secs = Math.floor((ms / 1000) % 60);
var mins = Math.floor((ms / 1000 / 60) % 60);
var hours = Math.floor((ms / 1000 / 60 / 60) % 24);
var days = Math.floor((ms / 1000 / 60 / 60 / 24) % 365);
var years = Math.floor(ms / 1000 / 60 / 60 / 24 / 365);
trace(years, "years", days, "days", hours, "hours", mins,
"minutes", secs,
"seconds");

Countdown timer to NEXT WHOLE HOUR..?

Hello.
I need to create a countdown timer function.
Normally that would not be a problem for me, but this timer needs to countdown to the next whole hour. As an example, if the time is 23:42 the countdown would say 17:35 (17 minutes, 35 seconds).
When the timer hits zero, it will start from 59:59 and so on.. Always counting to the next whole hour.
Im kind of in a jam and need this done ASAP, any help would be greatly apreciated!
/ Rasmus

Im sorry if i implied that im a great actionscripter, im not
What i would normally do is just grab a counter script from a google search and modify it to countdown to the correct time, but i havent been able to find a counter that counts down to the next whole hour.
It should just be plain and simple and display the time in minutes and seconds like this: 25:14
I found this one on google, counting down for christmas. If that could be modded into showing only minutes and seconds and of course counting down to the next whole hour, that would be awsome!

Insert a countdown timer in Keynote?

Hello all,
I'm sure this is an included feature that I just can't find somehow. I would like to insert a countdown timer into a slide. This seems pretty common; I've seen it done a lot. But I just can't find the Insert>timer link, or anything like it. And the iWork help file is forever searching and never going anywhere (second, embedded problem), so I can't search there.
I tried the iPresentee thing, but it didn't download properly. Plus, it seems like a basic feature available for a presenter, especially since there's a timer included in the Presenter view.
Any help would be appreciated. Thanks.

d moon,
Keynote does not provide any countdown timer features. You need to seek third parties for them.
The iPresentee timers are a good start - their website provides a free "goodie" of timers in the form of a Keynote File where many choices of timers are available. Try downloading the file again or contact iPresentee for assistance.
Each Timer is actually a Quicktime video clip. You select the one with the closest time range to your needs, copy it to your presentation and adjust the start point.
