Question

Basically I need the “image” of fast changing numbers. I am planning on having a series of these in a line, sort of like the matrix (how the numbers change repeatedly). I want them to basically generate the numbers 0-9 over and over pretty fast (sort of like milliseconds on a stopwatch), until I have them fade out.

I am fairly new to flash, so if you guys could help me out with a code I would greatly appreciate it!

Answer 1

As stated to get a random number between 0 and 9, Math.random is the way to go:

var n:int = Math.floor(Math.Random()*10);

But to address your second question, of how to get it so it does this every millisecond

import flash.utils.setInterval;
import flash.utils.clearInterval;

//variable for the intervalID, 
//and the variable that will be assigned the random number
var rnGenIID:uint, rn:int;

//function to update the rn variable 
//to the newly generated random number
function updateRN():void{
    rn = random0to9();
    //as suggested, you could just use:
    //rn = int(Math.random()*10);
    //but I figured you might find having it as a function kind of useful, 
    //...
    //the trace is here to show you the newly updated variable
    trace(rn);
}
function random0to9 ():int{
    //in AS3, when you type a function as an int or a uint,
    //so instead of using:
    //return Math.floor(Math.random()*10);
    //or
    //return int(Math.random()*10);
    //we use:
    return Math.random()*10;
}

//doing this assigns rnGenIID a number representing the interval's ID#
//and it set it up so that the function updateRN will be called every 1 ms
rnGenIID = setInterval(updateRN,1);

//to clear the interval
//clearInterval(rnGenIID);
