Date Calculation
Hello,
I searched through the forums and couldn't find exactly what im looking for. Basically i have a Trivia flash movie that changes the trivia each day. I have 365 trivia questions set up and need to be able to calculate what number day it is of the year. Using typical date functions only gives me the day of the month and i need it on a 365 day basis.....so i can change the trivia for a year without it repeating.
Thanks in advance,
Chris

Date Calculation
Hello,
I need some help!
I need to subtract two dates from each other and come up with a numeric value that will be used in another calculation.
For example:
070107 - 06/28/07 = 4 days
I've looked for conversion to julian date and actionscript and have not had any luck.
Thank you for any help you can provide.

Date Calculation
Hello,
I have a basic question regarding calculating the difference between two days.
The user will enter two dates in input text fields and I need to calculate the number of days difference between them.
For example a user may enter 092307 as the from date and 092607 as the to date. I need to have the number display as the number of days between them.
Thank you for any assistance you can provide.

Date How Can I Calculation Two Different Dates Using DateField Component ?
Hi,
I have 2 dateFields and I want to be able to select dates from them and get an answer, of how many days difference there are ?
I can do this without using the dateField.
The code I have for first dateField is :
var dcListener:Object = new Object();
dcListener.change = function(evt_obj:Object) {
var SelectDateate = evt_obj.target.selectedDate;
//BELOW Selects date from DateField Component
var date_str = (SelectDate.getDate()+(SelectDate.getMonth()+1)+Se lectDate.getFullYear());
var minutes = 1000 * 60;
var hours = minutes * 60;
var days = hours * 24;
var today_dateate = new Date();
//Calculate today_date into No. of days
var dnewer = (today_date/days);
//Calculate selected DateField into No. of days
var datefield = date_str/days;
//Calculate difference in days
var caldatefield = (dnewer-datefield);
//Place selected Date, from Datefield into Text box SelectDF_txt
SelectDF_txt.htmlText = true;
SelectDF_txt.htmlText = date_str ;
//Place Calculated Date, into Text box DiffDatefield_txt
DiffDatefield_txt.htmlText = true;
DiffDatefield_txt.htmlText = caldatefield ;
}
dateBoxH_ca.addEventListener("change", dcListener);
The second dateField is similar to above.
Thanks,
Paul

Convert RSS2 Date Format To Flash Date() Object
How can I take an RFC 822 (RSS 2) formatted string, and read it into a Flash MX Date() object. Flash does'nt like the format.
I have a function that will break the string apart the long way but is there an easier way to accomplish this - I can't believe flash would'nt have it built in like .NET or ColdFusion.
Thanks!

Bad Data From Date.getDay() And Date.getMonth()
I am trying to utilize the Date class to retrieve the current date, and populate fields for each date part. However, the day and month returned from either the day/month properties or the getDay()/getMonth() methods are incorrect: today is 4/11/2008, yet I get back a month of 3 and a day of 5!
Here is the relevant code:
var curDate:Date=new Date();
NewProjectStartMonthField.text=String(curDate.getMonth());
NewProjectStartDayField.text=String(curDate.getDay());
NewProjectStartYearField.text=String(curDate.fullYear);

Comparing Current Date With Date String
Im loading in a date from a database and storing it in a string called dateToCheck. The dates I am loading in from my datebase could be anything so I want to check if its past, present or future but as its a string and not a date when I compare to the current date it doesn't seem to work.
Im storing the current date in actions script like this
var today_dateate = new Date();
var date_str:String = (today_date.getDate()+"/"+(today_date.getMonth()+1)+"/"+today_date.getFullYear());
Do I need to convert the value date value Im loading from my database into a proper date before I can check it agains the current date? If so is there any easy way of doing it.

Date Generation Without Using Date Function

departure date. The script works in some cases but not
others. You can view this work in progress at:

Countdown To Date, Loading Date From Txt
Hey everyone,
I'm working on a Flash movie to countdown to a certain date, and I am wanting to assign that date in a .txt file so it is easy to change the date without modifying the FLA.
Here's the ActionScript I have for finding the date it's counting down to from the .txt file:
loadText = new loadVars();
loadText.load("date.txt");
loadText.onLoad = function() {
eventDate = new Date(this.year, this.month, this.day);
};
And the date.txt file has this in it:
year=2003&month=12&day=25
It doesn't seem to be working :- .
Any help would be awesome .

3d Calculation
http://www.nlc.net.au/~oceana/3d/3d.htm
On the webpage are 2 graphics which explain my question (I'm not so sure about figure 2). I need two equations;
-----------------------------------------------------------
Figure 1. I want to derive (x3,y3 - the point at which the line intersects with the plane) from the other co-ordinates (x1,y1,z1),(x2,y2,z2),(x4,y4,z4),(x5,y5,z5),(x6,y6 ,z6),(x7,y7,z7)
-----------------------------------------------------------
Figure 2. Rotating a point: I want to derive (x2,y2,z2) from (x1,y1,z1), a1, a2
-----------------------------------------------------------
First and formost, i'm stupid.
I've looked at the 3d tutorials and movies and again...i'm stupid.
-----------------------------------------------------------
If anyone could give me these 2 equations, USING THE VARIABLES THAT I HAVE GIVEN, you would be single handedly responsible for unleashing the worlds stupidest flash coder into the world of 3d.
Finally, i'm stupid... should have paid more attention in school.
Any help is greatly appreciated, thanks!

Hi everyone.
I know what I am asking is a very simple thing.Its simple calculation.
But I am just not able to figure it out. Please help.
What i want to do is make a simple calculation on some question like
How old are you
i.under 15 we will award him 4 points

iii.30 to 50 we will award him 2 points
iv.50 plus we will award him 1 point
How much do you weigh

Ideal body weight in kilos is your height in centimeters minus 100. So if you are 175 centimeters tall, you can be up to 75 kilos. Your ideal weight range would be between 72.5 – 77.5 Kilos.
Users within the weight range get 5 points
Users 1 – 5 kilos above or below rangeget 4 points
Users 6 – 10 kilos above or below range get 3 points
Users 11 – 15 kilos above or below range get 0 points
Users 16+ kilos above or below range get -10 points
The maximum score that a user can get is 9. That is for users who are under 15, within their weight range.
I want to know how would I calculate the weightage and the different varitions in weight ranges.
I am also attaching the FLA.

Pause In Calculation?
Hello,
I've made a flash to calculate some numbers.
There are lots of calculations to be done in the press of one button but for some reason the correct end result is not reached unless i press the calculate button twice.
Here is my code...
function onCalculate() {
one = Number(Head);
two = Number(Forequarter);
three = Number (Hindquarter);
four = Number (Gait);
five = Number (ntb);
six = Number (coat);
seven = Number (size);
eight = Number (temperament);
nine = Number (showshine);
ten = Number (feet);
eleven = Number (headsop);
twelve = Number (forequartersop);
thirteen = Number (hindquartersop);
fourteen = Number (gaitsop);
fifteen = Number (ntbsop);
sixteen = Number (coatsop);
seventeen = Number (sizesop);
eighteen = Number (tempermentsop);
nineteen = Number (generalsop);
twenty = Number (feetsop);
twentyone = Number (headsoptotal);
twentytwo = Number (forequartersoptotal);
twentythree = Number (hindquartersoptotal);
twentyfour = Number (gaitsoptotal);
twentyfive = Number (ntbsoptotal);
twentysix = Number (coatsoptotal);
twentyseven = Number (sizesoptotal);
twentyeight = Number (temperamentsoptotal);
twentynine = Number (generalsoptotal);
thirty = Number (feetsoptotal);
headsoptotal = one*headsop;
forequartersoptotal = two*forequartersop;
hindquartersoptotal = three*hindquartersop;
gaitsoptotal = four*gaitsop;
ntbsoptotal = five*ntbsop;
coatsoptotal = six*coatsop;
sizesoptotal = seven*sizesop;
tempsstotal = generalsoptotal*temperamentsop;
generalsoptotal = (eight+(nine/2))/2;
feetsoptotal = ten*feetsop;
sum = headsoptotal + forequartersoptotal + hindquartersoptotal + gaitsoptotal + ntbsoptotal + coatsoptotal + sizesoptotal + tempsstotal + feetsoptotal;
total = sum*10;
}
I think it has something to do with the caculations in the bold line,
tempsstotal = generalsoptotal*temperamentsop;
I just want to be able to press a 'calculate' button once and for the program to work it all out in one go any idea's anyone?
Thanks in advance

I have price * amount = total
amount is an input box
so the user can input any amount they require
press a button and it will work out the total
CalculatePrice = function (answer) {
P = Price;
A = Amount;
the_total = P*A;
return the_total;
};
submit.onRelease = function() {

The above works
got that work working but i need lots of these, now am a bit stuck here is the code that does not work:
CalculatePrice = function (answer) {
P = Price;
A = Amount;
P1 = Price1;
A1 = Amount1;
the_total = P*A;
the_total1 = P1*A1;
return the_total , the_total1;

Flash Calculation
I have 4 digital display components with instance names mat, oat, rat and %oa
I’m trying to write a flash calculation that computes mat and displays the result
My formula is mat = (oat-rat)(%oa) + rat
The operator would input the outside temperature (example 85)
Then they would input the return air temperature (example 72)
Then they would input the percent outside air (example 10% or .1)
Then the operator would press a button and the values would be plugged into the equation and computed and the answer displayed on the mat display
Mat=(85-72)(.1)+ 72
Mat = 73.3
Variables are:
Mat is mixed air temperature
Oat is outside air temperature
rat is return air temperature
%oa is percent outside air
curTemp1 = mat.val; this reads the value of the display
curTemp2 = oat.val; this reads the value of the display
curTemp3 = rat.val; this reads the value of the display
curTemp4 = %oa.val; this reads the value of the display
how would I write the code for this

Calculation Help Needed
Hi There,
I'm a bit new to actionscripting. I'm creating a calculator in flash, basicly recreating something that was created in excel. My questions is, is there any tutorials or any sample code that someone could point me to where I can learn from. I'm basicly looking to have a user enter data into about 12 text input information and then after that execute calculations based on the inputed information.
Thanks in advance for any help.

Reverse Calculation
Okay, I'm going to ask someone a huge favour..
I have been working with this all day but cant seem to figure it out..
Math problem again
anyway, I have a function that calculates y based on a property called Y, and some other variables as well, like z, in order to get the perspective-view I want for my game.
and in my editor i've made, I have what you could call a reversed version of that function. it calculates the Y based on y, so I could click the mouse somewhere and it would place it at the right Y in gamespace.
At first this was easy to do, when the calculation looked something like this.
ActionScript Code:
y= horizon+Y*z+z/10;
then the reversed function would look like this.
ActionScript Code:
Y= (y-horizon-z/10)/z;
that's pretty simple, altough I admit that does confuse me a bit.
and now when I have added more compexity to the function for more depth I just cant manage to reverse it. this is what it looks like...
ActionScript Code:
y=int(horizon+z/ground*(600-horizon)+(Y+(0-(Y*Y)/(((600-horizon)/18.5)*(600-horizon))))*(z/100));
yep, that's a big bad one. I started out with cutting out almost all of the function, then adding bit by bit while updating the reversed function.
I only got as far as this..
ActionScript Code:
y= (Y+(0-(Y*Y)));
reversed version:
ActionScript Code:
Y=y-(y-(Math.sqrt(0-y)));
and now it gets confusing, I cant even think straight, all I do is moving around the divisions and stuff and hope it will give the correct result.. but im not getting anywhere =
I really hope someone would help me with this, even if just pointing me in the right direction.
Any comment would be welcome.
Thank you =)

String Calculation In AS3
I have made this StringCalc class in AS3, which parses a string into objects and then calculates it. Before I made it, I googled around to check if there existed anything like it, but i could only find unanswered questions asking for the very same thing, or unfinished attempts.
Now I am throwing this out here, both to share it and hopefully to get some suggestions on how to make this class more efficient. It also proably contains bugs, and should do more errorhandling. All comments are appreciated. I have coded it in Rambo style, it does the job, but looks rather messy. I would think there are better practises, but im not very experienced in this kind of coding.
It currently support addition, subtraction, division, multiplication and ordered operations (parantheses)
Usage:
trace( StringCalc.calculate("4*(2+10)") );
Test with this example here
PHP Code:
package no.muldal.math {
public class StringCalc {
public static function calculate(value:String):Number {
var s:String = value;
// Convert nonenglish comma desimal delimiters to
// english dot
while (s.search(",") != -1) {
s = s.replace(",", ".");
}
// These two loops beneath appends the proper
// multiply sign when a formula is written
// like 2(2+2), and converts it to 2*(2+2)
for (var g:int = 0; g < s.length; g++) {
if (s.charAt(g) == "(" &&
s.charAt(g-1) != "(" &&
s.charAt(g-1) != "+" && // if operator is already assigned, skip
s.charAt(g-1) != "-" &&
s.charAt(g-1) != "*" &&
s.charAt(g-1) != "/" &&
g != 0 // if it is not the first char
) {
s = s.substring(0, g)+"*"+s.substring(g, s.length);
}
}
for (var h:int = 0; h < s.length; h++) {
if (s.charAt(h) == ")" &&
s.charAt(h+1) != ")" &&
s.charAt(h+1) != "+" && // if operator is already assigned, skip
s.charAt(h+1) != "-" &&
s.charAt(h+1) != "*" &&
s.charAt(h+1) != "/" &&
h != s.length-1 // if it is the last char, dont append
) {
s = s.substring(0, h+1)+"*"+s.substring(h+1, s.length);
}
}
// Code beneath sorts out the ordered operations
// into a xml structure. I used XML cause it was
// easy to debug and navigate in.
var equation:XML = <equation/>;
var currentOrder:XML = equation;
var startIndex:int = 0;
for (var i:int = 0; i < s.length; i++) {
var o:XML;
var e:String;
if (s.charAt(i) == "(") {
e = s.substring(startIndex, i);
if (e != "") {
currentOrder.appendChild(e);
}
startIndex = i+1;
o = <order/>;
currentOrder.appendChild(o);
currentOrder = o;
}
if (s.charAt(i) == ")") {
e = s.substring(startIndex, i);
if (e != "") {
currentOrder.appendChild(e);
}
startIndex = i+1;
currentOrder = currentOrder.parent();
}
if (i == s.length-1) {
e = s.substring(startIndex, i+1)
if (e != "") {
currentOrder.appendChild(e);
}
}
}
// This traverses the operations in the correct
// order and calculuates them accordingly
var t:Function = function(order:XMLList):* {
var eq:String = "";
for (var j:int = 0; j < order.length(); j++) {
if (order[j].nodeKind() == "text") {
eq += order[j];
} else if (order[j].localName() == "order") {
eq += arguments.callee(order[j].children());
}
}
return calc(eq);
}
t(equation.children());
return t(equation.children());
}
// The calculating function. Splits the operation
// by operators into objects in an array, which
// makes it easy to calculate the actual equation
private static function calc(eq:String):* {
var startIndex:int = 0;
var a:Array = new Array();
for (var i:int = 0; i < eq.length; i++) {
var o:Object;
if (eq.charAt(i) == "+") {
o = new Object();
o.operation = "add";
o.value = eq.substring(startIndex, i);
a.push(o);
startIndex = i+1;
} else if (eq.charAt(i) == "-") {
o = new Object();
o.operation = "subtract";
o.value = eq.substring(startIndex, i);
a.push(o);
startIndex = i+1;
} else if (eq.charAt(i) == "*") {
o = new Object();
o.operation = "multiply";
o.value = eq.substring(startIndex, i);
a.push(o);
startIndex = i+1;
} else if (eq.charAt(i) == "/") {
o = new Object();
o.operation = "divide";
o.value = eq.substring(startIndex, i);
a.push(o);
startIndex = i+1;
}
if (i == eq.length-1) {
o = new Object();
o.operation = "none";
o.value = eq.substring(startIndex, i+1);
a.push(o);
}
}
var result:Number;
// If there is no value, insert zero.
// I.e. if a user has written -2+2, this equals to
// the equation 0-2+2 etc.
if (a[0].value == "") {
result = 0;
} else {
result = parseFloat(a[0].value);
}
for (var j:int = 0; j < a.length; j++) {
// If there is no value, insert zero. Prevents
// script from breaking, when users insert stuff
// like 2+++2, which translates here to 2+0+0+2
// Probably should return error instead?
if (j != a.length-1) {
if (a[j+1].value == "") {
a[j+1].value = "0";
}
}
if (a[j].operation == "add") {
result += parseFloat(a[j+1].value);
} else if (a[j].operation == "subtract") {
result -= parseFloat(a[j+1].value);
} else if (a[j].operation == "multiply") {
result *= parseFloat(a[j+1].value);
} else if (a[j].operation == "divide") {
result /= parseFloat(a[j+1].value);
}
}
return result;
}
}
}
My usecase is a project I am working on that has a WebService that returns formulas in a string. Later I will add support for translating predefined variables which exist in the same WebService. Then it will be able to calculate i.e. (Tp*Sp) where Tp is bound to a slidebar etc.

Strange Calculation
Hello Friends,
I'm doing a simple calculation here like :
Gamma = _root.Punit;
Neutron = stepperMain.value;
Sigma = Gamma + Neutron;
trace(Gamma);
trace(Neutron);
trace(Sigma);
totalPrice.text = Sigma;
------------------
And if Gamma is equal to 13,90
and if Neutron is equal to 2
the result is 13.92 !!!! super !! Grrrrrrrrrrr!
if you can help !
thanks

Problem With A Calculation
Hi there!
i have a little problem with a calculation i do not know how o solve
here's some actionscript (this happens in a enterFrame function):
PHP Code:
diff = _root.s_line._y - this._y;
pos_y = _root.s_line._y - (diff * 0.75);
pos_x = 506 / 100 * prozent_ablauf;
draw_point(pos_x, pos_y);
diff is the distance from a line to a specific point, for example 50pixels. this scripts calculates steps from these 50pixels down to 0, whereas the steps always get a little smaller.
is there a way to do the opposit, so that the steps in the beginning are smaller and then always get a little bigger until they reach 0?
thanks for any help :-)
manuel
