I have problem about math. I want write function of laplace transform in flash.
X(s)=kd*s^2 +kp*s+Ki;
F(s)=s^3 +(10+kd)*s^2 +(20+Kp)*s+Ki;
Gc(s)=X(s)=/F(s);
How I write code(actionscript) in flash, when Kp Ki Pd is value of user input. And S is Laplace transform.
How can I make Flash calculate the value of the function y= (1 - x^2)^3 where x is the user input value?
View 3 RepliesI am new to Flash and Action Scripts. I am trying to put together some Mortgage Calculators for a client and am having issues getting the syntax for the formula correct. Below is my code could someone look it over and give some pointers on how to structure the formula. It is a standard mortgage payment calculator. num1 is Loan Amount num2 is interest rate and num3 is loan term they are the instance names of the unput text boxes.
equels_btn.addEventListener(MouseEvent.CLICK,equel sClick);
num1.border = true;
num2.border = true;[code]........
I get the folowing error when I click the equels_btn
TypeError: Error #1006: value is not a function. at LoanPayment_fla::MainTimeline/equelsClick()
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'm having trouble with loading in an external image that I can transform with the Senocular Transform Tool class. I have managed to load in the picture but the transform class doesn't seem want to grab it. Eventually I want to us the FileRef to upload the image but I just need to figure out how it works first. Here my code to load in the external image
[Code]...
The transform class can grab the other movieclips but it doesn't want to grab the new image loaded in from the code above.
I have the following code in actionscript 3:
var async:AsyncToken;
async = bridge.retornamenu();
The bridge is a remote object, instantiated. The retornamenu() is the function that I want the remote object open in amfphp.
However the retornamenu() is a dynamic function, which turns another function, but I can not run it at runtime,
example
var stringfunction:String = "retornamenu()" // this name is dynamic.
var async:AsyncToken;
async = bridge.stringfunction;
But this way does not work, not perform the function retornamenu();

I wonder how to make a Math.random() function, or something similar where it chooses a number from 0-9. But as the program progresses, another random variable will appear. That random value is what I want removed from the 0-9 scale. (The other random variable is also from 0-9)

View 2 RepliesI am generating random numbers between 1 and 90 how do I do it so I don't get any repeats. Here is the code I am using.
ActionScript Code:
var num:Number = Math.ceil(Math.random()*90);
I cant get this to work. I think its pretty self explanatory what I want to do, set _x to a random position (b1 - b6)
Code:
onClipEvent (load) {
stop();
b1 = 462;
b2 = -462;
b3 = -1388;
b4 = -2314;
b5 = -3240;
b6 = -4166;
} onClipEvent (load) {
RanNum = Math.ceil(Math.random() * 6);
_x = ["b" + RanNum];
}

View 3 RepliesI'm new to Actionscript programming. I'm trying to figure out what is the best way to return multiple variables, each having a different data type, from a function. For example, if a function needs to return variable aa ( a string) and variable bb (a number).
The function I'm using just crunches a lot of math, and doesn't relate to an object in a GUI. One method I got from a Google search used an Object, but as (I think) this requires me to create a class, I wondered if there was a simpler way. Since an array can hold elements of different data types, perhaps this is a simpler approach (?). [code]...

View 2 Repliesi have a web application that runs inside a iframe. The iframe is scaled with -webkit-transform:scale(0.8), thats works pretty good but my flash audio recorder inside that iframe doesn´t work when the iframe gots scaled. The flash selfs got loaded and works but the SecurityPanel on which the user has to allow the access to the microphone, is not clickable.
Maybee someone has the same problem or any idea what i can do to fix that?
So here is a piece of code that I have seen used a lot but don't really quite understand:
myVar = Math.min(Math.max(myVar, this.min), this.max);
or some variation thereof. I understand that the function first finds the maximum value of two values then turns around and uses that to find the minimum between two values.why this is done? And how do you know when to use it?

View 1 RepliesI'm trying to get familiar with design patterns, modularity, unit testing and etc... (with ActionScript). I'm developing a simple "Free transform tool" right now, just as a exercise, but I don't like the solutions that I come up with so far, so I'll try to walk you trough my line of thoughts. When I come up with the idea I was thinking "What to write so I can test this great Unit testing framework FlexUnit", the first thing that I saw was guess what.. a free transform tool. :) When I was thinking about the architecture of the tool I run every scenario trough "How can I write unit tests for that thing?", so I come up with some kind of twisted MVC meta pattern:
A view that's holding all components (rotation area, drag area, resize buttons)A model (or something like that) that holds the necessary logic (setSize, setPositiom, rotateAroundCenter, etc..).And a controller that add listeners to the view components, update the mouse cursor when its over a component, get the mouse coordinates when is interacted with a component, do the calculations and call methods from the model that will update the view and the object that is benign transformed.
I was thinking: "Ok its flexible, i can switch M, V or C at any time, I achieved my main goal, because I can make lots of unit test for the model, where the important calculations are, so its great..".I just have started implementing it, but I think most of those thoughts are wrong. Yes I can change the view and add new skin but it's not flexible at all, if I want to add "skew" (or any other) functionality I should rewrite (or If I'm lucky just extend) M, V and C.Yes I can make bunch unit test for the model but controller's calculations will be hard to test.
So now I'm thinking for something like the Decorator pattern that will allow me to create whatever combination of controls i want to use and keep their logic separated, but I want to have the option to re-skin the controls themselves and to keep the logic separated so I can do the tests.I realize I want to create some kind of "ultimate transform tool", but I'm really trying to push my limits and learn something.
I've noticed there is something in AS3 that allows "shearing or skewing" of an object, but I was wondering if it's possible to do the equivalent of what Photoshop refers to as "transform>>perspective"
View 3 RepliesI'm making a matrix effect thing using AS3. Everything is going good except for color transitions.
Basically i have two bitmap images, one is where the leading white letters are falling, another is where the letters are printed on to, and i use a color matrix filter to slowly fade the letters away and tint its color.
And this tinting of color is what im having problems with right now. My method works for colors like 0x00FF00, 0xFF0000, or any colors with only 0s and Fs. Other colors with hex values between F and 0 will inevitably turn into a color of 0s and Fs or jus turn black, due to ...

my idea right now is to scan through each pixel and add its RGB component individually checking if it has reached the designated value or not, but ive no idea how to go about doing this and i think it might cause lagg.

View 2 RepliesI'm working on a project wherein a user can take a snapshot of themselves using their webcam and then edit this image by transforming scale and rotation and save the result.
I've got most of it working, the user can take a snapshot of themselves, transform the object using Senocular's Transform Tool and i'm using .draw() to then save this transformed object. The problem is .draw() is only grabbing data from the top left corner of the stage. It is drawing the transformed object but only from the top left corner.
Why does it only draw from the top left corner and how can i get set the coordinates to only draw from the area where the captured image is set?
