I was wondering if anyone out there can point me to a forumla for generating random numbers that are weighted within a specific range.I need to generate random numbers between 1 and 100. However, I'd like the most of them to cluster between 1 and 30, with proportionaly less chance of them occuring above 30.
View 5 RepliesI'm trying to devise a (good) way to choose a random number from a range of possible numbers where each number in the range is given a weight. To put it simply: given the range of numbers (0,1,2) choose a number where 0 has an 80% probability of being selected, 1 has a 10% chance and 2 has a 10% chance.
It's been about 8 years since my college stats class, so you can imagine the proper formula for this escapes me at the moment.
Here's the 'cheap and dirty' method that I came up with. This solution uses ColdFusion. Yours may use whatever language you'd like. I'm a programmer, I think I can handle porting it. Ultimately my solution needs to be in Groovy - I wrote this one in ColdFusion because it's easy to quickly write/test in CF.
public function weightedRandom( Struct options ) {
var tempArr = [];
for( var o in arguments.options )

how to do this and not found much, so here goes:

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.

ActionScript Code:

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?

Basically what I need to do is I'm populating a library with a for loop with specific clips that need to be in a random order but never duplicates.So basically, it get selects a random number between 1-6 and if that number hasn't been selected yet, it will run it will use it as my integer in my for loop then continue running the loop until numbers 1-6 have all been used, but never used twice.

I have a custom slideshow that I've made that has a set of four images changing every 5 seconds. The images are randomly selected by a random number between 0 and the length of my XML.
how can I get four unique random numbers - i.e., getting 1, 4, 6, and 8 rather than 1, 4, 6, and 6?
So once a random number is selected, it can't be selected again.
I need some actionscript that will give me a random number between -50 and 50. Been looking at it for a while now.
The main thing is, I need to create a random value which could be a neg or a positive number, on every frame. So far I can create a random value, but can't get it to be neg one frame and positive the next.

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:

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.
how would i get a random number between 1-5 but excluding one of those numbers?
like i want to generate

or
