Flash :: Math: Significant Digits

Significant Performance Gain Through Optimisation
Hi all, I've been creating a flash presentation over the last couple of days which basically shows 200+ slides as mini thumbnails which all move, resize etc.

Unsurprisingly this was a little laggy, but was improved with some cacheAsBitmap, less alphaing and less drop shadow & bluring.

However, the thing that has saved the project from slow, impending doom, was to never set any property of a MovieClip unless it had to change.

For instance:

ActionScript Code:
thumb.onEnterFrame = function(){
//The following causes unnecessary idle cpu load
this._x = 100;
//This removes (most of) this unnecessary idle cpu load
if( this._x != 100 ) this._x = 100;
}

I've ended up replacing every single property assignment in the project with a function that takes the a MovieClip, a property and a new value and only changes it if necessary. This has radically improved performance!

For example:

ActionScript Code:
//No more:
thumb._x = 100;

//Instead i have:
pSet(thumb,'_x',100);
}

This is something that I will end up implementing on all my future flash projects, but it's not exactly graceful... I could prototype a function to do this on the MovieClip object, but really I want to overload the setter function for all _ properties in the MovieClip class. Sadly I don't believe this is possible.

Has anyone else been down this road before and found any elegant solutions?

Cheers, James

Progressbar Does Not Work In Significant Long For Loop
I have a long for loop which takes significant amout to load everything in my flash application. the for loop takes around 5 seconds...

I want to show a progress bar during that time. I used onEnterFrame... but it wont update the progress bar MC during that for loop execution... It starts after for loop finishes.. . . Also I tried to put updation of progress bar in for loop along with updateAfterEvent ... but nothing work....

Two Digits
This gives the remaining time in a song. I want the seconds to display as two digits 09 for example instead of 9 what is the easiest way to do that.

thanks alot

nbstot = (_level1._totalframes)/12;
nbseco = (_level1._currentframe)/12;
nbsleft = nbstot-nbseco;
time_left = int(nbsleft/60)+":"+int(nbsleft-(int(nbsleft/60))*60);

First Two Digits...
Hi there!

I manage a directory of former students of my school.
Users who want to register must indicate in the form the year they entered the school.
Alas, some of them enter bad years, like "0972" instead of "1972" or "0674" instead of "1974" !!!

Inside a general Validation function, I already have an Array using different validating functions (one for each Field) into which I use "push" to enumerate different mistakes and prevent them with warnings and disabling of the Register Button. Like this one:

validatePromo = function () {
if (_root.promoField.length<1) {
errors.push("- You MUST indicate the year you entered the school.");
}
if (_root. promoField.length<4) {
errors.push("- Year must be four digits long.");
}
if (promotion<1925) {
errors.push("- Enter 1925 as promotion year.");
}
}

What I don't know is how to write the if statement to force user to begin the year string with 19 or 20.
Could you please tell me ?

Many thanks in advance,
Regards

Last Two Digits Of A Variable
Hey!

I have a question, let's say I have a Variable, Variable A. Variable A is probably over 100. I want to take the last 2 digits of it (so it if was 117 it would be 17, 3415315 = 15 etc.) and make those last 2 digits into a new variable, variable B.

Is there a way to do this?

so for example, if a number is 14.5:
ones = 4
tens = 1
tenth = 5

Animating Digits
Hi All,

how is everyone doing? Fantastic over here. AND even better if one of you could help me with the following. When looking at the attached, what I`m``trying to do is, animate some digits, which are randomly entering the screen from the left (maybe I can define an are with a mask), then in step two form a large digit (square quadrat) and after some time leave the srceen randomly again to the right. But when I mean randomly, it mustn`t necessarilly be random, important is that the digits come in consequently.
thanks for any advice in advance.

Best,

Three Digits For Text Preloader...
Hi, I have a small question. In my preloader, I would like to have three digits (eg. 001, 002,...035,036,...099,100). How would I go about doing this? Right now my script contains:

code: bytes_loaded = Math.round(this.getBytesLoaded());
bytes_total = Math.round(this.getBytesTotal());
Percent_Loaded = bytes_loaded/bytes_total;
this.load_text = Math.round(Percent_Loaded*100);
if (Percent_Loaded >= 1) {
gotoAndPlay(37);

Extract Date With 2 Digits:
I've used a time stamp to get my date and then extracted it with the following:

var timeStamp = new Date().toString();
var today = new Date();

this works but it gives me one digit results for the month and day such as:

My customer needs 02/02/2006.

[CS3] Round Numbers To 2 Digits
hi there... i have a dynamic textbox that is populated by the user selecting an item from a combobox... everything works fine except i would like my numbers to have 2 decimal places (like: 4.00, instead of just 4)

i see there's lots of stuff online concerning this and Actionscript 3, but i've coded the entire work in Actionscript 2 and can't change it...

the closest thing i have now that makes any sense to me (even though it doesn't work) is something like this:

Code:
_root.MC1.DynamicField = 9;
var num = _root.MC1.DynamicField;
var str = num.toFixed(2);

any thoughts?

Limit The Digits. 1.392846 To 1.392
I want to limit a numbers length without rounding cieling or flooring it. I want to cut off the last digits.

For example:
1.83251931

I want as:
1.83251

It's for a simple math game. The user must input an answer, and I will frustrate them if is I round the solution.

Math.round(number*1000)/1000;
is the closest I have to limiting the values, but round is bad.

Displaying Value Of Variable As 7 Digits
I have made a simple counter in flash that updates live via a php-file that writes to a txt-file. The variable "count" is used to import the number from the txt-file into a dynamic textfield in flash with:

this.loadVariables("count.txt?num="+random(999));

The counter works fine but I want the counter to always display 7 digits, for example 0000025 instead of just 25. This should be fairly simple but I don't know how or if it should be done in flash or php as I am fairly new to both. I am working in flash 8 btw.

Can anyone lend a hand?

Seperating Digits Using Flash Substrings
Hello All.

I am trying to retrieve data from a server and display it in a font that does not space dynamically the way that my boss, the art director wants it to look. The server will send me 2 and three digit numbers thaty need to be displayed, but because of graphical issues, each digit (first, second, or third) needs to be placed in different dynamic text boxes. I asked the programmer to break up the number in asp and send it as three different variables for me to rearrange in flash but this is a no go. SO i need someone to show me how to "seperate the digits using substings" any takers?

any help would be appreciated.

thanks.

MP3 Player, Trouble Displaying 2 Digits
Hi,
I'm new here so please go easy on me

I looked you up for a question regarding a Mp3 jukebox type thingie. It's going quite well (I'm redesigning it for educational purposes). But.. I'm having difficulties displaying two digits. You know, when Flash goes below 9 it's not 09 anymore..

I've tried other scripts and tutorials out there to fix it, but without luck. Any help would be appreciated.

The time related coding appears in three places:

ActionScript Code:
nbstot = (_level1._totalframes)/12;
nbseco = (_level1._currentframe)/12;
nbsleft = nbstot-nbseco;
time_left = int(nbsleft/60)+" : "+int(nbsleft-(int(nbsleft/60))*60)+" ";

ActionScript Code:
if (nbsleft == none) {
} else {
nbstot = (_level1._totalframes)/12;
nbseco = (_level1._currentframe)/12;
nbsleft = nbstot-nbseco;
time_left = int(nbsleft/60)+" : "+int(nbsleft-(int(nbsleft/60))*60)+" ";
}

ActionScript Code:
nbstot = (_level1._totalframes)/12;
nbseco = (_level1._currentframe)/12;
nbsleft = nbstot-nbseco;
time_left = int(nbsleft/60)+" : "+int(nbsleft-(int(nbsleft/60))*60)+" ";
if (cge == 1) {
if (loop == 0) {
unloadMovieNum(1);
loadMovieNum("./movie" + i +".swf", 1);
titre_chanson = eval ("titre" + i);
}
if (loop < 3) {
loop = loop + 1;
gotoAndPlay(21);
} else {
cge = 0;
loop = 0;
gotoAndPlay(20);
}
} else {
gotoAndPlay(20);
}

Best regards,
Marius.

Checking User Input To Limit To Certain Digits
I'm doing a simple binary converter where I want only the digits 1 and 0 input into a box.

Everything works great except I need to check the string (from the input text box) to make sure it's only 1's and 0's. The check is performed when they click on the convert button.

I can do this in other languages using regular expressions, which ActionScript doesn't seem to have, so what's the best way to check user input to limit it to specific characters?

Keep in mind the string can be up to 40 characters long, so manually checking each digit would probably be inefficient.

Do I need to use substring for this?

Thanks.

Controlling The Odds Of Math.floor(Math.random()
Hey,
Is there a way to set a random number in a array to showup maybe once a day. Or every 5000 views or loops, or something like that. I would love to be able to control the odds of a array. Cheers!

ActionScript Code:

pic_array[0] = "images/1";
pic_array[1] = "images/2";
pic_array[2] = "images/3";
pic_array[3] = "images/4";
pic_array[4] = "images/5";
pic_array[5] = "images/6";
pic_array[6] = "images/7";
pic_array[7] = "images/8";
pic_array[8] = "images/9";
pic_array[9] = "images/10";
pic_array[10] = "images/11";
pic_array[11] = "images/12";
pic_array[12] = "images/13";
pic_array[13] = "images/14";

ranNum = Math.floor(Math.random()*pic_array.length);

Setting Dynamic Number To 3 Digits? Hard To Explain...
Howdy howdy!

Quick and hopefully simple question. I've got a dynamic text box named "course" and this box is set at a certain number at the start of my movie. As the user hits buttons, this number increases or decreases.

I have on my buttons that if course > 359, it goes back to 0. (Can't have more than 360 degrees right?) This works fine.

Anyway, just found out this number can't go back to 0, it has to go to 000, and count up 001, 002, 003,... etc.

Is there a simple way to do this? I can't figure it out. I can't get it to display the three 0's at all.
Thanks so much in advance. Hope someone can help!

Index Xml Target.name.length And Double-digits Issue
I have an issue, I have about 25 mc's that are named carBtn1 through carBtn25 - the problem is when I index my array - its only taking the first number from the end of the carBtn, so carBtn1 is seen as the same as carBtn10. I tried taking the last 2 digits off which works for 2 digit numbers - but everything below 10 isnt working anymore. Im not sure what to do to get it working....

Here is my code:

Code:
// variables
var popInfo:popMc;

// load xml
var xml:XML = new XML();
var loader:URLLoader = new URLLoader();
loader.load(new URLRequest("data/cities.xml"));
loader.addEventListener(Event.COMPLETE,
function(evt:Event):void {
xml = XML(evt.target.data);
//trace(xml.city[0].@weburl.toString());
var url:URLRequest = new URLRequest(xml.city[0].@weburl.toString());

}
);

// event listeners
stage.addEventListener(MouseEvent.CLICK, onClickStageRemove);

for (var j:int = 0; j < 11; j++)
{
getChildByName("carBtn" + j).addEventListener(MouseEvent.CLICK, onClickLoadData);
getChildByName("carBtn" + j).addEventListener(MouseEvent.MOUSE_OVER, onCarHover);
getChildByName("carBtn" + j).addEventListener(MouseEvent.MOUSE_OUT, onCarOut);
}

// button mode
buttonMode = true;

// functions
function onCarHover(event:MouseEvent):void
{
event.target.gotoAndPlay(11);

}

function onCarOut(event:MouseEvent):void
{
event.target.gotoAndPlay(10);
}

function onClickLoadData(event:MouseEvent):void
{
popInfo = new popMc();
popInfo.x = 100;
popInfo.y = 50;
addChild(popInfo);
popInfo.closeBtn.addEventListener(MouseEvent.CLICK , onClickRemove);
popInfo.nyopBtn.addEventListener(MouseEvent.CLICK, onClickNYOP);
//better approach would be add separate classFile to haldle some popInfo's events
//such removing on stageClick in that file u could add those functions:
var index:Number=event.target.name.slice(event.target.name.length-1);
popInfo.carsizeText.text = xml.city[index].bidlist.carsize.descendants().toXMLString();
popInfo.priceText.text = xml.city[index].bidlist.price.descendants().toXMLString();
popInfo.savingsText.text = xml.city[index].bidlist.savings.descendants().toXMLString();
popInfo.stateText.text = xml.city[index].@name.toString();
addChild(popInfo);
}

function onClickRemove(event:MouseEvent):void
{
popInfo.closeBtn.removeEventListener(MouseEvent.CLICK, onClickRemove);
popInfo.nyopBtn.removeEventListener(MouseEvent.CLICK, onClickNYOP);
removeChild(popInfo);
}

function onClickStageRemove(event:MouseEvent):void

Adding 3 Months To The Date Object (and GetFullYear Displaying Last Two Digits)
I'm currently working on a simple project displaying a date and I've got this so far:

myDate = new Date();
dd = myDate.getDate();
mm = myDate.getMonth() + 1;
yyyy = myDate.getFullYear();
textdate = (mm+"/"+dd+"/"+yyyy);

Works great. Displays proper date like 6/20/2006.

However, here's where things get interesting. Clients wants date to display 3 months into the future. Now sure, I could just use myDate.getMonth() + 4 and it'll work. Sort of. Of course, what if it's 3/31 and since there's no 6/31, that'll look kind of stupid. So what's the workaround for this? Got to be something.

Also, any idea how I can just make the year display as '06' instead of '2006'?

MATH: General Math Ratio Formula?
So I have these sets of values that correspond with other values. But the manufacturer only gave me sets by 5. I need to break it out for every integer. Here's what I got ...

25=54
30=78
35=106
40=138
45=175
50=216
55=261
60=310
My question is how do I develop a formula in Flash that can give me values for numbers not divisible by 5? Accuracy to the nth power, figuratively speaking, isn't crucial.

Big thanks,
