ActionScript 2.0 :: Generating Random Numbers From Normal Distribution
Jul 30, 2004
We are in the process of builing a statistics simulation for a client. One of the requirements of the simulation is to first generate a set of 1000 random numbers from a Normal (or Guassian) distribution.Does ActionScript have the builty in functionality to generate random numbers from anything other than a Uniform distribution?If this functionality is not built in, does anyone know of a component or pre-built script that can provide this functionality?How hard would it be, if either of the two options above are not possible, to generate random numbers from a Normal(Guassian) distribuion using ActionScript?

i'm attempting to populate an array with random numbers, but the random numbers must be a certain, minimum distance apart from each other.i've populated an array with 5 random numbers between 0 - 100:[code]after populating and sorting let's assume that myArray now contains these values:26, 27, 42, 92, 97 now i would like some ore all of the array values to be reset, if they need to be, so that they are at least a certain percentage (let's say 10%) of the maximum value (100) apart from each other.the first 2 values (26 and 27) are not at least 10% apart and neither are the last 2 values (92 and 97). however, if i simply moved the value 27 10% away from 26, so that 27 changes to 37, 37 now conflicts with the next value of 42.what is the best approach for populating an array of random numbers who's values will be at least a certain percentage apart from one another but still random.it may go without saying, but i'm looking for a solution that is portable, where maximum values and minimum distribution percentages can be anything, not just for my example above.

I am generating random numbers between two numbers by the code bellow:
ActionScript Code:
public function randomRange(max:Number, min:Number = 0):Number
{
return Math.round(Math.random() * (1+max - min) + min);
}
trace(randomRange(3,-31));
But I need a code which will return some times '3' and some times '-31'. Not the number between them.

hi, i'm generating two random numbers, between 1 and 4, which must be different to each other each the two numbers are picked. i've tried the following:
var firstRandom = Math.random()*3+1;
var secondRandom = Math.random()*3+1;
var boxA = "box"+(Math.round(firstRandom));
[code]....
and i still get two numbers the same occasionally. why isn't it comparing the numbers?

generating random numbers between 50 and 200 but the number that has been generated once should not be displayed again. I am using this code
var num:Number;
on(release){
num = Math.round (Math.random ()*200);
trace(num+50); // +50 because random numbers between 50 and 200 are required
}
Its working fine but sometimes repeat the number that has already been displayed.

I'd like to create a very simple random addition equation.I have: 3 dynamic text boxes (r1_txt, r2_txt, a1_txt)I want the first two to be random numbers and "a1_txt" to display the sum of the first two random numbers.Everything's perfect up to the point of adding the two numbers together and dropping the answer into a1_text. What do I need to do to my last line of code?
//random numbers//1.function randomNumbers(min:Number,max:Number) { var Results:Number=Math.floor(Math.random()*max)+min; return Results;}
//2.new_mc.addEventListener(MouseEvent.CLICK, showRandomnumber);
//3.function showRandomnumber(event:MouseEvent):void{ r1_txt.text = randomNumbers(1,100) r2_txt.text = randomNumbers(1,100) a1_txt.text = Number(r1_txt.text) + Number(r2_txt.text);}

So basically I am making a round robin function, for someone, basically a round robin, matches every player with every player, im having alot of trouble with this, its quite difficult heres an example of the site i've been copying off (his matches are preset though)
[URL]
My current code generates about 10 "undefineds" each launch I do My code gets the input entered (which is the amount of players) It generates how many players based on that input my graph I have is 10 columns long, and 19 rows down I need to match player
1, vs 2 - 20,
2 vs 3 - 20,
3 vs 4 - 20,
4 vs 5 - 20

I need to generate 238 numbers, with a range of 1-4, but I want to weight them, so there's say 35% chance of getting 3, 28% chance of getting 2, 18% chance of getting 4m, and 19% chance of getting 1.

I am trying to use Jim Bumgardner's Clumping example ([URL]) to create an interface. Part of it is that I am creating clusters of bubbles (one parent bubble with n child bubbles). The child bubbles all follow the parent, so far so good. Next step is to create a random distribution of these clusters. So the clusters all need to be n pixels away from each other. My idea was to build this into the clumping algorithm. I.e. if one parent is too close to another parent, their x and y will increase/decrease with a value. Also I am trying to let the clusters stay in the boundary of the stage. Simply by adding to the algorithm the bubbles should move n pixels to the left when they are too close to the left border of the stage (same principle for the other 3 sides).
Problem is that it kind of not works what I am trying. I extended the algorithm so far that it became a mess difficult to see what's going wrong (see attachment). Can somebody help me with describing how I can improve the Clumping algorithm so that it meets my requirements (1. Clusters distributed randomly, 2. Stage boundary collision)? Pseudo-code is also okay

I Have started to learn AS3 from scratch and have decided to create a simple maths game for small children. The game consists of multiplication and division. I have everything working accept for this one last thing that I'm just not sure how to tell Flash what to do. Basically there are 2 text boxes that randomly generate a number between 0 and 12. The 3 box is where the user enters their answer. They press check and the code checks to see if box 1 divided by box 2 equals box 3.
However what I want to do is ensure that only whole numbers are used and that the number can actually be divided. I told I need to use this method but I don't know how to implement this in Flash AS3. "For division, the trick is to generate the question, but make sure that the product of the two random numbers is actually displayed in the first box (product / rand1 = rand2) otherwise you get difficult sums..."
Here is my current code:
function divSetup(){
displayRandomDivNumber();
}divSetup();
var divQuest1:String;
var divQuest2:String;

I m doing a project and had an idea of doing a math game thing where numbers are randomly generated in two slots. For example one is between 1 and 100 and the other the same, and then adding them together. The player would have to add them together then type them into the the answer box and it would tell if it was correct or not. I need help with the coding as I am new to CS5.I have worked with an older, outdated version of flash a little over a year ago. So I somewhat know general things and some of the things that need to be done. Actionscript though is pretty new and I was trying to use math.Random because thats what it seems like everyone is using in their tutorials. Yet, I couldn't get it to work when playing around with it.

how to do this and not found much, so here goes:
I want to generate a variable number of random numbers less than 16 with no duplicate numbers
Ive posted the fla, and what i'm doing is generating a random number and putting it into an array then using a for loop to cycle through the array for each new random number to check if its already there. if it is, then i want to regenerate that number.
if you test the fla you'll see that all i get in my array is some lovely zero's and i sort of know why this is, but don't know how to stop it.

Making a random number between lets say 0 and 99 is relatively straight forward using the Math.random class What is the best way to create 100 unique random numbers from between 0 and 99 where no random number is repeated?Would I make a random number, chuck it into an array then the next random number created is checked against the array, and if the number has been created before try for another number?

What I'm looking for is to have a button on the screen. When clicked it will generate a random fact. I'd like to have around 25 facts, although the number doesnt matter at this stage.
I'm only learnigng flash and actionscript at the moment so my thoughts are a bit confused. Would I store all the facts in an array and use the math function to generate a random number that will access the fact stored in the array? not sure how the code would look like.

I have an engine for platformer game and I need to generate random blocks while moving and of course delete old ones, when the hero leave pervious position.Here is the code for generating random platforms when the game starts (costructor):
ActionScript Code:
public function TheGame()
{
bla-bla...
[code]....
As you can see, I create a loop which creates 10 platforms in different positions.My goal is to create a function which will delete blocks from the array which are not in the stage anymore and create new blocks when screen is moving up.

I am making a game where random letters and words are generated into movieclips, thats the background. I built it using arial as my font, however I then decided to go with a fixed width font to make sizing the movieclips to the words much more straightforward. Yesterday this worked fine, the font i am using (Liberation Mono) is installed on my computer, all the textboxes which use this font have the character embedding on them, and I have not changed any of the movieclips, only non-relevant code. So I run it up again today and none of the words appear. Thinking it might be some code changes I made I go thourhg tracing out everything, only to find the wrds are being generated, and written to the textbox absolutely fine. I switch back to Arial just as a check and bang it works again.

I heard of some Math.random() but I'm not sure about using it correctly. Number must be whole, so I suppose I'll need some rounding function.

I'm assigned to do the portfolio section for my company's website and my supervisor has specifically told me what he wanted in terms of navigation and layout. Basically, he wants each portfolio piece to be square and in the form of 7 x 7 square grids. Each square's dimension is 100x100 px. He wants each portfolio piece to load randomly every time the page loads, so that it makes a shape of jigsaw puzzle-like if the piece is less than 49. Each image needs to be imported externally so that when we have more portfolio, we can simply added it to the array. Each portfolio piece should behave like a button that links to a bigger image.I was able to get it to the point where the squares are generated dynamically on 7x7 square grids ( I used script from "Flash Hacks" book by Sham Bingal) Now I'm trying to develop the script to get it to work like my supervisor wanted.

I'm trying to write code for webcam tracking + drawing generative lines. Main idea is that person passes the camera and it creates random size and colours lines. After lines fill screen up to 35%, screen become blank (as in the begining). So my questions are: 1. how to create random size and colours lines that appears by person tracked movement? (example could be that person is creating generative art by lines) 2. what functions should I use to count percents of filled screen? (I want that after 35% screen become blank as in the beginning. After that it just continue process from the beginning)

I looked everywhere on the internet and couldnt find how to generate a random number that had one decimal place.I am trying to generate numbers between 12.0 and 13.0 randomly.Below is my code... I know its wrong because of Math.round and Math.random, but i cant seem to find anything that deals with a decimal place.
addEventListener(Event.ENTER_FRAME, fl_EnterFrameHandler_1);
function fl_EnterFrameHandler_1(event:Event):void{volt.text = Math.round(Math.random()*(1)+12).toString();}
