ActionScript 2.0 :: [FMX] Array Math, Graphing Functions
Dec 2, 2003
I want to make a graph. Specifically, a graph of a normal population distribution.I think (please correct me if I'm wrong) that the best way for me to do this is to use two arrays for coordinates and use the lineTo function to connect the dots:
- An Index array up to about 300 as the "x-axis"
- A Second array to represent the "y-axis" created using the formula for normal population applied to each entry of the index array
So I need to create these two arrays in FMX. the first array i think should be created with a For loop: for(i=0;i<a.length;i++){} The second array somehow applying my formula to each entry in array 1.I believe my methods are correct, but I am having a great deal of trouble getting the AS down properly and I can't find many good sources on it.

often seen in simple flash games. So you can look at an example. http:[url]....Green object shots a bullet and what i want to acheive is to run bullet toward black bar even if bullet is shot to the left side of the screen. Bullet should make a circle, slow down and change direction to the bar and finally proceed faster and faster to the bar. Simply it should behave like remote control rocket chasing enemy. Right now i am with this: Code: Select all
function movingBull(e:Event):void [code].........
//of course i dont know what should be inside if statement
//to make the code work.

I am learning AS3 and I try to remake an SimDate game. I have studies the functions and the Steps of the game and now I try to make the Functions myself.
I have 5 Attributes:
Strength
Knowledge
Charm
Health
Dollars
For each of them I have defined a variable. Now I need to make an math function. If I want to raise str:
statusstrenght = statusstrenght + addstr
This code is not the original. My other code is down below. I only wanted to show the process.
addstr == Math.random() *5
I wanted that the variable statusstrenght starts with 10. If I press the train Strenghtbutton the action addstr will be started and updates the statusstr with the new value. That's what I had in mind but I cant define the new value off statusstrenght + addstr. Do I have to add a new variable with newstatusstrenght or can I just overwrite the value of statusstrenght if I press the train strength button ?
Here is the code. The math functions aren't working. It is AS3.
import flash.events.*;
var statusstrenght:Number = 10;
var statusknowledge:Number = 10;
var statuscharme:Number = 10;
var statushealth:uint = 100;
var statusdollar:uint = 100;

So, right now when I want to find the distance between two points, I go: dist = Math.sqrt((this_x-that_x)*(this_x-that_x)+(this_y-that_y)*(this_y-that_y)) BLECH! I don't want to do that every time. So I want to make a nice little function that I can apply to an object. Problem is, I don't know how to do this. Is it possible to end up with something as easy as: Math.dist(thisclipname, thatclipname)? How do you guys set up functions that do bulky math and return nice clean numbers?

ActionScript3 states the following:
Note: The Math functions acos, asin, atan, atan2, cos, exp, log, pow, sin, and sqrt may result in slightly different values depending on the algorithms used by the CPU or operating system. Flash runtimes call on the CPU (or operating system if the CPU doesn't support floating point calculations) when performing the calculations for the listed functions, and results have shown slight variations depending upon the CPU or operating system in use.
My web application works with very large and small numbers that I suspect may see a difference depending on which machine is running it (especially with mobile devices whose processors aren't as powerful as desktop machines'). My question is, is this behavior a function of the language?
That is, I assume some languages implement their own algorithms for the above functions, and so may be more consistent (except for differences in round-off errors introduced by the choice of processor/CPU that would exist for all languages).
Anyone know if Javascript has it's own algorithms, or does it outsource them to the CPU/processor like ActionScript?

We have the WebApplication portal. We are generating the stats survey, which needs to displayed on graph. We have started using HighCharts. As a requirement analysis, I would like to know, what are the other alternative for Charting and Graphing. Can you advise/discuss, which is more efficient,effective way of charting? What are the pros and cons for each platform? Any more other alternatives ?

Is there a flash widget that can read, say JSON/XML data, and create an interactive network graph that which users can drag nodes around? I'm not looking for software that creates static images... but something more dynamic, like "heavier" the node, the bigger it looks. That kind of Flash widget.

Here is the problem:
var p:int = 0;
var n:Number = 0;
n = 32.999999999999999;
p = Math.floor(n);
trace(p); // returns 33
n = 32.11111111111111;
p = Math.floor(n);
trace(p); // returns 32
I would expect both of these to return 32. I have searched, and it seems this is an unreported bug in AS3. Or ... am I doing something wrong?

I have a code in which I have to use Math.round if a certain value is for example 3.67 (67 is higher than 50) and Math.ceil if a value is for example 3.23 (23 is lower than 50). What can I do to make flash calculate if what after the dot �.� in 3.23 (for example) is higher than 50?

Suppose you have a round based RPG type game. The player issues directives to his units, your enemy AI issues directives to its units. The problem is that the functions for those directives then have to be executed in a specific order with no relation to the order they were input in and all at the same time with the push of one button.
I just need a little direction here, I just spent the last fifteen minutes searching "AS3 Array of Functions" before figuring out that maybe that's not the way you do it in AS3.
Essentially, I'm looking for the way to store functions, put them in a list to be sorted in a specific order and then execute them in said order.

is it possible to sort array elements using more than one sorting function? My problem is this: I want to sort an array firstly for one property of the objects inside, then with the help of a function and again with the help of another function...
I've tried doing this:
ActionScript Code:
tempHand.sortOn("pubNum", Array.NUMERIC);
tempHand.sort(Suit.sortSuits);
tempHand.sort(Deck.sortDecks);
becase everytime I use the sort function the previouse sorting is confused =

Is there a way to store functions in an array so that I can then call the _array[num] to call the function? The _array will be sorted that is why I am wanting to call the functions through the array.I am using the Tween class's onMotionFinished to create a series of events like pan, zoom, fade, etc.Because the order of the sequence of events will likely change based on user interaction I am not able to hard-code the onMotionFinshed to perform a specific function. So I figure I would store the functions in a function_array and use a counter var to store the current location in the sequence of events. Or maybe a "pause" & "resume" command inside of a for loop?

I have an array that I have set up that would go with a series of movie clips, and I am trying to combine them with functions that upload xml pictures--firstImage(), secondImage(), and so forth.
Here is the array that I have:
Code:
var currentButtonId:Number = 0;
var buttons:Array = [btn1, btn2, btn3, btn4, btn5, btn6];
function buttonRelease() {
[Code]....
It enables and disables the movieclips depending on which one is clicked. But I want to make the xml functions (firstImage(), secondImage()...) go with the buttons in sequence. So once btn1 gets pressed the firstImage() xml function gets called.

This is where I'm at now with the code. It works to an extent, but doesn't lock out the other bArrays when the first one is clicked. I would like the code to stop bArray2 & bArray3 from functioning when a button in bArray1 is clicked. Is this at all possible?[code]...

I want to do something where I collect functions to be invoked later when a certain condition is met. E.g.
function doSomething(someArg:Object):void {
if (conditionIsFalse){
operationsToDoWhenConditionIsTrue.push(function(){
doSomething(someArg);
[Code]...
Basically if doSomething is called twice, I only want operationsToDoWhenConditionIsTrue to hold the most recent invocation. Obviously since the invocations are wrapped in function(){} all the functions are the same. Is there any way I can accomplish what I want?

How would I go about evaluating an array of strings as function calls?Something like this:
ActionScript Code:

var myArray:Array = new Array("function1()", "function2()", "function3()");[code]....
I get an error "Instantiation attempted on a non-constructor".In this case, I'm trying to dynamically add linked movie symbols from the library. Perhaps I'm going about this the wrong way... ?
