Does anyone know the math to create this type of spectrum?
I'm using the F8 bitmap object and this image for a color preferences panel, and would like to use the same image for a fall-back to F7.
For F8, I'm using getPixel(), for F7 I'll need to determine the color (or as close an approximation as possible) using the math used to create this type spectrum.
Code: Select allimport caurina.transitions.*;
addEventListener(Event.ENTER_FRAME , kop)
function kop(e:Event):void {
dot.x = mouseX ;
dot.y = mouseY ;
[Code]...
What i done there i draw a box and made it to movieclip and instance named it hook and created a invisible dot and called it dot. Then I calculated distance from box to the mouse then i took that number and put it in Math.cos command. And finally i made tweener to change box scale depending what my mouse distance from it.So if my mouse is close the box is big , if far - box is small. Ok, I want to know is there another way to do this ? Cuz , i cant think of other way to change arithmetic positive progression(like 3,6,9,12) to negative progression(like 12,9,6,3) than Math.cos command.
been a fan of this great site for ages. [URL] One thing i really like about the site is that when you get into a section, you will see at the bottom of the section the numbers 01 , 02 , 03...ect.. progressively load into the movie, which when they are loaded in are active and can be selected whilst the rest stilll are preloading.
View 10 Repliesi am trying to get my text progression to flow right to left but flip it so that instead of tiliting your head to the right to read it you would tilt your head to the left...i had orignally transformed and flipped the text box which worked for english text. but there is an option to change the language to chinese and when you do, the chinese character display upsidedown..
View 2 RepliesI have XML data that looks like this: 197,168,198,168,204,168,206,168,207,169,208,etc This stuff is XY coordinate pairs, X1, Y1, X2, Y2, X3, Y3, etc. and are used by a drawing function to trace out a particular freeform shape. This array of data is usually 200-400 items long.Here is the AS code that is handling the reading of the XML and the drawing of the shape. This all works wonderfully:
[code]...
I am looking at the array and grabbing some points out, namely the first and last XY pairs, which I need for something else. That's the origXexp, origYexp stuff.The real problem is that I need to run a mathematical calculation on the data in this array. While this is a little hard to explain, I need to create a variable, let's call it expert_area, and then sequentially rip through that long string of numbers and do the following math (I'll use the simple X1 Y1 example): expert_area=0 expert_area = expert_area+((X1*Y2 - X2*Y1)/2)
where we move through the long string a pair at a time. So the first calculation would be (X1*Y2 - X2*Y1), the next would be (X2*Y3 - X3*Y2), (X3*Y4 - X4*Y3), etc. I've tried building loops to get the length of the expertArray[i] and then using that as the basis to proceed through the data. But everything I try either produces no results, or gets Flash stuck in an infinite loop. I'm unsure of where to put this, and how to construct it.
Does anyone know of a parser for math functions?
Basically, I want to be able ot take a string such as:
(x + (x - 3)/2 * 4)^2
and compute the answer. Before I make the parser on my own, I thought I'd check to see if anyone has something similar already made.
Is there anyway I can display exponents or fractions properly in a textfield.
I'm creating educational software and want to see actual symbols as opposed to: 3/4 or x^2
I admit it. I'm a mathematical imbecile. should I be attempting this at home? Probably not without serious injury. Anyway. Anyone that has a bit of experience in games and physics who can review this code and provide insight into why there is a built in "loss" in velocity in prototype would be hugely admired.
the concept: the actor falls from the sky, at some point intersects a boundary (trampoline.y) after which gravity (in this example a value of 1.6) stops operating and a restitution factor (in this case a value of -6) takes over.
right now I'm trying to create a zero-sum situation where you have the same velocity coming out of the trampoline "bounce" (hero.y >= trampoline.y) as you did going in. That's just not the case as the traces reveal.
[Code]...
For now I'm hoping to have a solution where the velocity on the tic after the character leaves contact with the trampoline is the same (but negative) of the velocity just prior to going in. Heck I've even tried storing and retrieving the entry position and velocity, but that just looks like a hiccup.
I'm trying to create a balance beam for an education video game and am having trouble making the balance look just right.When the student slides the weight on a triple beam balance, the beam rotates from its pivot to show how far off the weight is. The student then continues adjusting it until the weight matches. My problem occurs because the length of the weight arm means the rotation values are very small, range -4 to 4 degrees, and when the student gets within a few grams it appears level.
My question is how to create a mathematical curve. Like 100 = 20, 50 = 15, 20 = 10, 1 = 4, .2 = 2, etc, so that I can have large movements towards the more accurate side and less when the weight is far off.
I've gotten stuck on some issue using AS3 and RegEx. I'm trying to use a RegEx var to match out the ends of a mathematical expressions out of a string. But for some reason, the RegEx only matches the first expression and ignores the one after the conditional.
[Code]....
I'm completely useless at maths due to paying no attention whatsoever to it in school when I was a kid so forgive my lack of knowledge of basic terminology.I need a mathematical function that will return a number based on a graph that starts at 0, curves to (eg.) 100 and then curves back down to 0. I have a feeling it has something to do with Math.sin or somesuch wizardry but am not sure.Basically, I want to feed it a number between (eg.) 0 - 60 and for it to return a number on aforementioned curve. The purpose of this is to be applied as a lateral force on some basic ball physics. The idea of the 'curve' is that (depending on timing of the shot) there will be a 'sweetspot' in the timing.
View 5 RepliesI'm developing a project with Flex, Spring, Hibernate, MySQL, Tomcat, but one of the functionality is: " i have to store a mathematical rule like for example " a+b " into database, then in my human machine interface, i have two fields when user write the variables "a" and "b", then a button with the label calculate which if it's clicked, it'll show bellow the result of applying the rule " a+b " to the variables "a" and "b" which the user previously." Now, i'm searching for an Java or Flex API or any other way that will give me the ability to apply a mathematical rule stored in database as string, to variables i got from human machine interface"

I have made a MP3 Player in which spectrum bars acts on Sound.. I used computeSpectrum function from SoundMixer Class. Everything is going well.... But when I run my player and open any other player (from You tube for example) in the same window then Spectrum bars stops responding. I want my players Spectrum bars should not be interrupted even if other player is opened in same browser window,.... is it possible ??
View 3 RepliesHow we can draw a color spectrum in AS3 using for loop?
View 3 Repliesi've come across this ActionScript sample, which demonstrates drawing of the color spectrum, one line at a time via a loop, using waveforms.however, the waveform location of each RGB channel create a color spectrum that is missing colors (pure yellow, cyan and magenta) and therefore the spectrum is incomplete.how can i remedy this problem so that the drawn color spectrum will exhibit all colors?
// Loop through all of the pixels from '0' to the specified width.

I looking into become a sound programmer. As I could find some sound analyzer would display a nice spectrum of color on bitmap. Which API do I draw a dot shape? Is it circle or line? Is it possible to resize the bitmap width and height after adding all the dots?
View 1 RepliesI know the SoundMixer.computeSpectrum and Sound.extract() methods , but those methods deal with the total sound output. Instead, is there a way to deal with every single SoundChannel, so as to provide a graphical visualization of each of them?

View 1 RepliesJust wanted to ask, is it at all possible to create sound spectrum from the data that RTMP server streamed? I read this computeSpectrum and it says
"In addition, this method cannot be used to extract data from RTMP streams, even when it is called by content that reside in the same domain as the RTMP server."
I will not be using FMS so it stays inpossible. Are there any available hacks with php and the server or whatever?
