digital countdown

[n-10]

Hello,
I haved searched the forums for hours now trying to find a conclusive answer to this prob, as I am very short of time to get this sussed, but to no avail!
I am trying to create a digital style clock that counts from 7.00 minutes down to zero, showing minutes, seconds and (possibly) milliseconds. Can anyone help me with this as time is running out!! (excuse the pun!!)

Thanx in advance! :O)

You searched the forums for hours? Hmmm...

Anyway, this will get you on your way:

code:

---

this.createTextField ("timer", 0, 100, 100, 250, 20);

timer.text = "7 : 00";

minutes = 7;

seconds = 0;

function countdown () {

        seconds--;

        if (seconds == -1) {

                minutes--;

                seconds = 59;

        }

        if (seconds < 10) {

                seconds = "0" + seconds;

        }

        if (minutes == 0 && seconds == 0) {

                clearInterval (timerInt);

                trace ("time up!");

                //do something

        }

        timer.text = minutes + " : " + seconds;

}

timerInt = setInterval (countdown, 1000);

Cheers for yr reply, but where would I put this code? inside an empty movieClip or just on the main timeline, or do I need to create a dynamic txt box? Sorry to be a pain :O)

[mngn9drb]

Well the code I gave you creates its own textfield just for the purpose of demonstration, but you can create your own dynamic textfield, but make sure you give it an INSTANCE name of 'timer'. The code can go anywhere you want it too, and as long as the textfield's referenced properly it'll work. Try pasting it 'as-is' into the root of a blank movie and you'll pick up how it works.

Have fun!

OK, i've got it to display the txt box, but how do i get it to actually start counting?!! sorry to bug you, but I really haven't got the time to try and figure it out, otherwise I would!!!

Thanx for your time and help :O)

[mngn9drb]

It should work straight away from the code above. The line:

code:

---

timerInt = setInterval (countdown, 1000);

---

Is the one that starts the counting - make sure you copied it with the rest of the code!

This code is for MX by the way, it won't work with 5...

[n-10]

I have copied the code exactly as you posted it, including the "timerInt", but the countdown does not start. is there a way of triggering it with a button? perhaps this is easier for me to get my head around!!!
Once again, thanx for yr time, and sorry for being a pain!

[n-10]

by the way, I am using MX as well :O)

AHA!!! finally sussed it! for some reason, when you copy & paste code from here into Flash it adds in spaces where they aren't needed so after a bit of fiddling (and some fine delaying tactics!) it all works fine!! Thanx for yr help! :O)

[mngn9drb]

Glad you got it working

[n-10]

Just a quick question for mngn9drb, if yr still around! now I have my countdown working, how would I go about putting a stop and a reset button on it?
Thanx :O)

[mngn9drb]

Just pick this apart - I'm not sure of how you've set up the buttons, but this code contains all the eventualities you may come across. If you're applying code directly to the buttons, just cut and paste the parts between the function declaration.

code:

---

stopped = false;

//code on the stop button

stopButton.onRelease = function () {

	//stop interval we use to countdown

	clearInterval (timerInt);

	stopped = true;

};

//reset button

resetButton.onRelease = function () {

	//reset back to defaults

	timer.text = "7 : 00";

	minutes = 7;

	seconds = 0;

};

//and some code to restart the timer again, if you want to!

startButton.onRelease = function () {

	//make sure timer has actually stopped

	if (!stopped) {

		//it hasn't? let's not go any further

		break;

	} else {

		//otherwise, lets restart the timer

		timerInt = setInterval (countdown, 1000);

		//set flag to flase for further presses

		stopped = false;

	}

};

Check the comments to see what stuff does.

Wow! cheers for yr speedy reply! I'll check it out now! :O)

[n-10]

works a treat! Cheers for all yr help!

[mngn9drb]

No worries. Glad to be of service!

[n-10]

Hey there mngn9drb! Its me again! Got another quick question for ya! Is there any way that during the countdown at 6 minutes I can tell a movie clip to play (one that sez 1 minute to go)? I really appreciate all the help yr giving me, thanx a lot!! :O)

[mngn9drb]

You just need to replicate some of the code to add an if statement in there to see if minutes == 1 and seconds == 0, play the countdown. Pretty simple. It's already checking the time anyway, so see what you can come up with!

[n-10]

Yep, sussed it after a bit of playin about. Just wanted to say cheers for all yr help again! much appreciated.
:O)

Hi ya all!

I'm creating a clock that I can set to start at what time I choose but when seconds go to 60, it starts to add zeros into the minutes.

Could someone point out whats wrong with my code.

this.createTextField ("timer", 0, 100, 100, 250, 20);
timer.text = "14 : 59 : 50";
hours = 14;
minutes = 59;
seconds = 50;
function countdown () {
        seconds++;
        if (seconds == 60) {
                minutes++;
                seconds = 00;
        }
	if (minutes == 60) {
		hours++;
		minutes = 00;
	}
        if (seconds < 10) {
                seconds = "0" + seconds;
		}
	if (minutes < 10) {
		minutes = "0" + minutes;
	}
        timer.text = hours + " : " + minutes + " : " + seconds;
}
timerInt = setInterval (countdown, 1000);

Nevermind, found it myself.
