[Flashcoders] Random numbers list
Hi all!
What I am trying to figure out is this:
How to generate a sequence of random numbers where the newest is always
different from all the previous?
I need to continuosly rewrite an array of 10 random numbers in such a way
that at any given time they are all different.
Let's say that my range is 0 to 100
it starts with random numbers, all different:
{3, 34, 12, 69, 6, 44, 31, 90, 88, 23}
at a set interval some values are replaced by new ones so there are never
two equal numbers, so, after 2 seconds it may look like this:
{3, 66, 12, 79, 6, 44, 10, 81, 88, 23}
Any ideas?
Thanks :)
Eduardo

Re: [Flashcoders] Random numbers list
Hi Matt,
Yes numbers can and should repeat through time. They just cant be repeated
within the sequence at a given discreet time. Makes sense? :)

Can numbers repeat? Is this a constant loop where, for instance, the
number 12 could show up two times in twenty seconds? Or would you want
12 to show up once and then go out of circulation permanently?

Re: [Flashcoders] Random numbers list
Hi Laurent,
Your first suggestion is a very simple and clever trick i'll definetely keep
in mind for future situations.
However for this second variation you mean that I:
1) pick the numbers out of array 1 and splice it
2) move those numbers into array 2
3) when the length of array 1 would be 10 i would start picking the numbers
out of array 2 and do the inverse.
Is this what you mean?

still it can be done like that you always keep the number of numbers
between two arrays...
and swap numbers from one to another, that your sure to neve have twice the
same one
yeah...! :]

Re: [Flashcoders] Random numbers list
Hi Steve,
That was actually my first thought. I had a while loop and inside a for ...
in loop to iterate through the array to check if the number was already
there. But then for some reason the script made flash unresponsive.
However I just came up with this which seems to be working, but i'm still
very curious to learn of better ways of achieving this:
function pickUniqueNumber():Number {
var randomNum:Number;
var loop:Boolean = true;
var numberList:String = |+currentNumbers.join(|)+|;
while (loop) {
randomNum = random(wallpaperList.length);
var numberString:String = |+randomNum+|;
if (numberList.indexOf(numberString) == -1) {
currentNumbers.push(randomNum);
loop = false;
}
}
return randomNum;
}

Every time you generate a new random number go through the array and see if
any match the new number if so generate a new one and check again, if not
add it to the array.
With only 10 numbers in the array it would check very fast so you wouldn't
be taking a performance hit.

Re: [Flashcoders] How do you delete child movieclips?
Hi Alexander, What I usually do is, at the same time that the child MCs are created, write them one after the other in an empty array that then you'll later call, run through it and delete all its contents. Makes sense? Let me know if you want me to copy paste some code I've written for your reference. Cheers!

[Flashcoders] bitmap import and loading efficiency
Hi list! (made a quick search in the archive as i guess this must be a recurrent/basic question but found nothing. hope one of you won't mind quickly helping me) About loading external bitmaps: If I want to compose a lettering in flash where each letter is a bitmap what would be more efficient strategy since there are repeating letters: a) load the same bitmap everytime? b) load only unique bitmaps and then duplicate them using duplicateMovieClip? c) something it hasn't occurred to me? Thank you for your time! P.S. any more detailed info on how flash manages the memory on this case will be very welcome.

Re: Re[2]: [Flashcoders] if logical operator
thanks you all so much! am amazed with the stormy brilliance of your replies! i was trying out something with arrays myself but definitely I have my problem solved now and learned a good bit more of actionscripting with you. Hope i'll be soon able to make some valuable contributions here too thanks again!

[Flashcoders] if logical operator
Hi all,
given a list of numbers such as: (12, 34, 21, 46, 52 ... )
what would be the best way to achieve this:
a++;
if ( a != 12 a != 34 a != 21 a != 46 a != 52 ... ) {
// do something
}
Am doing my research and trying out some solutions but i thought that in the
meantime someone may have a quick ready answer for this or some good hints.
thanks a lot!
Eduardo

Re: [Flashcoders] JERKY Animations
If the object you are trying to animate is a bitmap does it work if you uncheck allow smoothing in the bitmap properties? edo On 12/1/05, flo_web [EMAIL PROTECTED] wrote: Hi, we're trying to make smooth and slow animations on aircarft movment. But the result is JERKY and we couldn't reach a good result with smooth movment. All the tests was made in local so there is no bandwith and loading considerations. We tried lot of technics : - high frame rate (25-30) - guide - even an flv of the animation (aftereffect animation encoded in avi then in flv) is JERKY - translations in actionscript so PLEAAASE is there a good solution for that or can't we make a beautiful smooth slow animation !
